Device: Samsung Galaxy S GT i9000
Symptoms:
When Charging Device is hot to the Touch in the upper half of the screen and on the rear between the camera and the heat vent.
Battery drains at around 15-25% per hour when IDLE. 15% when in deep sleep in airplane mode with ALL APPS KILLED. 25% when I leave ALL network connections open and allow sync.
Phone was new less than 2 months ago. Still under warranty and I will send it back if no ideas come from this but wanted to see if anyone had a solution as I have noticed HUNDREDS of similar posts all vaguely scattered through different threads on different sites around the web and this seems like the definitive place to come to see if anyone can put their finger on it.
When did this occur?:
A short while after (days) of flashing CM9 nightly from the beginning of June (05/06 I think but can't recall exactly).
Tests performed:
Purchased new battery and fully charged - no change.
Flashed stock GB ROMs where the issue had not occured - no change.
Cleared battery stats several times - no change.
Tried different modems/radios including Nexus S radios- no result
Current ROM: CM 7.2
Kernel: Glitch 13.1
Other ROMs/Kernels where the same results were achieved...
CM9 (latest nightlies)
Stock JVU, JVS, JW4 and JW5
Semaphore Kernel, Devils Kernel
I use Voodoo Sound/Colour kernels apart from the testing I did with stock ROMs
Will leave it on over night after clearing stats so you can see for yourselves.
Any questions ask away.
I should add:
Used OS Monitor and one of the more detailed CPU monitors to look at what was going on.
Did not appear at any time to be using what I would consider high CPU utilisation, typically trending between 0 and 30ish. No background apps running, all radios turned off.
The only anomaly that stuck out at me is that system_server was using ~105% of RAM which I would have thought was rather difficult. Made me wonder if there was something loading/unloading itself from RAM.
As I am a heavy music user I have tested the Mediaserver issue where corrupt files are continually scanned by mediaserver process. Removed all media files from both my external and internal storage then formatted both while on a stock ROM (JVU and JW4). There was no change.
EDIT: I should add - The thing that makes this so strange to me is that the battery decreases at a rapid rate when Battery stats regarding usage DO NOT CHANGE. The percentages for the apps that WERE using the battery - i.e. winamp/mediaserver/android system do not change.
The reason I have posted this is that i have seen literally HUNDREDS of people posting this very same issue but never in the same place and never getting an answer.
Also - Thankyou to the kind mod/admin who approved my account so I can edit stuff. It was getting a bit annoying for the first week there.
Re
Hi,
To be honest I never heard/read of the problem you are describing. Most users report high battery drain on a certain ROM/kernel/modem but you say you have tried quite a lot.
If the phone is new, the only thing that comes to mind is that the USB charging socket is faulty. It may not charge properly or even have some bad connectors that are damaging the battery.
In any case, Samsung support is the way to go here.
Hope this helps
OMG, im having the same exact problem... the phone is super hot on the back where the sim card is inserted. I did everything as you, still no change, my battery lasts like 7 hours on deep sleep. Guess our phone is broken. super crap.
Anyone knows how to fix this? Is there anyway that my phone has some files from previous custom roms even though used odin to flash samsung original ones?
Had the same problem when my device was only 6 months old, the battery was becoming faulty, got a new battery and problem solved.
I bought a new battery and i still have the same problem... which battery did u get?

An official samsung battery from Amazon, re flash you device with another rom and wipe battery stats.
Did all that, the problem still continues... mega battery drain and the phone is at 44C degrees... is there any tool i can use to diagnose the problem?
Hi snaleman,
You could try BetterBatteryStats, to help diagnose your issue further, there is a paid version on the market (Google Play Store). There is also a thread on this forum, from the dev....hint
I tried winamp for android, ages ago, but had similar issues. (This player might well be your issue.) So I now use "PowerAmp". Neutron MP is cool too.
Also, do you use lippol94's kernel cleaning script. I use this every kernel/ROM change.
Search here for this:
ultimate_kernel_cleaning_script
Hope this info helps your baby.
Hey
U can try to flash a stock rom from sammmobile.com..
Use it for a few days and check...may help u..
Cheers

Backup your apps with titanium backup or something else.
Make a backup from CWM recovery
Wipe data/cache/dalvik
Restore user apps and not system app
If your problem is not fixed you can restore your CWM backup
Nothing you guys posted worked... battery lasts 11 hours on sleep...
Another problem that im facing is that when im on a phone call, theres is alot of breaks in the other persons voice and sometimes the voice call goes out and i lose all my network signal.
If you are using the Voodoo sound app that may be the cause. I've noticed on my phone that deep sleep no longer works when the voodoo app is installed, most likely the app is holding a partial wake lock and not releasing it.
See if it happens with the app uninstalled or frozen.

You've just made me think of something else that it may be.
Do you have 4 or 5 bars of signal strength?
I've found when in certain areas (very close to "deadspots" in network reception), that if I use another frequency, [eg. 900 & 2100 (for my network), yours may be different] I can get a better signal, also much better battery life, as the phone is not struggling to reach the network.
If you use your dialer to enter this code
*#*#197328640#*#*
Then
[1] DEBUG SCREEN
THEN
[8] PHONE CONTROL
then
[7] NETWORK CONTROL
then
[2] BAND SELECTION
you will then have a selection of frequencies available. The asterisk * will tell you what one(s) is/are active.
"Google" your network service providers frequency bands. I found mine were on a "Wiki" page.
7 hours off fully charged battery since the upgrade completed, and down to 10%. Anyone else with battery life issues since receiving the OTA?
edit: phone temperature also runs very hot now since the update-- Gingerbread was quite a bit cooler to run.
I briefly ran the 217 OTA build before installing safestrap and rolling to a Cyanogenmod image.
I noticed that my phone was MUCH hotter than it had been while running the older GB-based rom -- however, I can't comment on the battery life itself.

I've been running .217 leak for a few weeks, and found that if you have a lot of MP3s on an SDcard, the phone will run really hot while it builds the MP3 database.

It does indeed run much hotter with the screen on. Are you experiencing heat issues with Cyanogenmod, or was it only under the 217 OTA?

Was it a one-time or some-time thing, or was the phone constantly hot? Did you remove any of the files, or was there a workaround to prevent building the database?
It's been stated that initially expect very poor battery life immediately after upgrading to ICS and I would expect heat to be another factor as the CPU is in constant use updating all the new databases, sync'ing etc...that is going on.
(stated in the Motorola soak test forums to expect this).

+1 its expected. I always try to give new roms/updates at least 3 or 4 days to smooth itself out. Especially when upgrading from cupcake to froyo to gingerbread to ics.......

Mine ran hot for a day. The next day I restarted it and haven't ran hot for a while.

Yeah it should be better after a couple of three days. I can get 14-16 hours on network and 25-30 hours when on steady wifi.

It ran quite hot in the 217 OTA itself. Once I flashed over to cyanogenmod, it got cooler and has been running at roughly the same temperature as when i ran the GB rom.
I have very few MP3's on the SD card. It's actually the card from my old D1 and mostly has nandroid and titanium backup data on it
Odd, I haven't noticed any increase in heat, battery life is still good for me.
Upgraded OTA on monday, so 2 days now. I have a 32gig sd card, and the internal sdcard and the 32gig are loaded full of mp3's, a few videos, and titanium backups.
I want to say battery life is better than normal. But I believe this is only due to fixing a few issues over the weekend with misbehaving apps.

Alright, it's been four days and battery life still sucks-- the phone is now only charging to 60% capacity, and phone spontaneously reboots, runs hot and apps still crash... and then I read that V217 OTA is halted due to "software issues"-- what recourse do I have? I don't pay "insurance" (which works out to the price of a new phone in 2 years). Will VZW address or swap the phone given that this power issue and phone instability was due to software upgrade they prompted on the phone?
Strange... Powered off the Droid 4 before bed and plugged into charger. Woke up and it was at 100%. Powered on, rebooted into safestrap/cwm and wiped cache, Dalvik, and battery stats. Rebooted and left it on charger, in case of quick drain again.
Will see if wife still experiences issues during her day. If so then this is most likely software or OS issue and after I get home from work I'll have to try backup and FXZ to see if a clean OS and gradual install of apps / restore some old data resolves the issue.
Step 1 is hunting down D4 FXZ threads on XDA and checking what's involved.

I've been finding that the battery life and heat has improved for me since installing the OTA. I came from stock, rooted, Gingerbread 219. For the past month or so, I had been noticing that my phone was getting very hot just by charging it (could be due to some app that I couldn't narrow down), but that stopped after the ICS OTA.
Additionally, after the last GB OTA, I noticed that the keyboard lighting would shut off even in complete darkness. That also seems to be fixed with the ICS OTA.

I've had a couple of interesting issues since I updated this morning. First, my media files on my microSD card "disappeared" in that My Gallery no longer displayed pix and vids on the microSD card and Winamp couldn't find any of my MP3s. A reformat of the card seems to have fixed it, for now.
The other issue is that the battery seemed to drain much more quickly than it did when I had Gingerbread. I hope what was said here about that being the case for about the first day or so is true. I would hate to think that this is the nature of ICS.
Didn't do the FXZ / destructive reinstall yet; was doing some more investigation last night-- phone was draining about battery 10% every 10 minutes. The only two things showing under Settings-->Battery were Screen at 60% and Media com.motorola.android.omadrm at 40%. Rebooted, set to charge before bed and now this morning I see other items listed under battery: Android System, Android OS, Mail. Phone is now at 80% battery running on battery for the last 30 minutes. When the screen goes off and I turn it back on, I sometimes see "Battery Extender" flash in the status bar.
Did an
Code:
adb reboot bootloader
to get to the bootloader. Then did a
Code:
fastboot devices
and saw that the phone was listed. Launched RSDLite and flashed the fxz xml.zip file and all seemed well...
phone started up, there was a little android icon with gears spinning inside of it and a progress bar crossing. phone rebooted again, "optimized" android applications, and finally came back to the same system as before-- nothing got wiped. I guess I'll have to do a Settings/Privacy/Factory Reset to get an actual wipe.
Rather than doing a wipe, debating setting up safestrap, going to the safe partition and installing an alternate ICS ROM.
Before going that route at all, there are 27GB of about 7000 mp3 files on the external SD. I'm going to pull the external SD and see how battery life is first.
No battery benefit after pulling out the external SD card; still about 10% battery drain every 10-15 mins.
Did the Settings/Privacy/Factory reset-- currently at 30% drain in 120 minutes. Seems improved, but this is also without the external SD in the device.
Saw a few different things in forums, including searching through some of the alternate ROMs for D4 and looking at some of the Razr ICS upgrade battery issue complaints:
--some said they were having battery issues until doing factory wipe and then reinstalling apps from Play Store without restoring old data
--some said there was something stuck on their external sd that required a full re-format and then restoring data back to the external sd which returned battery life to "normal"
--others said that media indexing is taking place and to give it a few days (seriously? is there no way to disable this or uninstall whichever application is doing this??? the wife said she wouldn't mind scrolling through folders rather than having fully indexed media by artist/album/genre)-- And she raises the valid point, "It used to work fine before!" What changed between Ginger Bread and Ice Cream Sandwich to require this much indexing and what's the fix for it given that people can't return back to GB? Which QA engineer at Verizon/GoogleRola thought it would be a good idea to release an update with this massive issue? Is the intent to discourage people from listening to their locally stored music and to have them rely on data plan intensive "cloud services"? Is there some application that can do the indexing on a more powerful machine like a PC and then upload the indices / export databases to the phone?
140 minutes at 60%-- still at full factory resetted stock from this morning, no external SD card in phone, no media on internal SD card.
I suppose Plan B is to call Verizon and tell them that the battery life is complete crap since their update and to request a CLN-- hoping that it's not running ICS.
to clarify: no apps have been restored / reinstalled-- what on earth could possibly be digesting battery like this?
edit: saw someone's post suggesting settings/more.../mobile networks/network mode - preferred network = LTE/CDMA instead of Global. Giving that a shot.
Not sure what did the trick, but after observing 4 hours at 60%, and Disabling a bunch of the bloatware, re-added the external memory card (with all gazillion mp3s on it) and began installing previously used software. A charge later and a few reboots after, was getting 4 more hours with battery at 90%. No idea what did the trick as I ran through too many variables and never reset them to be able to isolate one specific one.
Good luck to anybody else that may experience this issue in the future.
Thanks for the report. I too did the factory reset and reformatted my card. I think I've had a tiny bit of improvement, but still go down to about 60% capacity after two hours away from the charger with moderate use (Facebook, Twitter, Tapatalk, etc., no streaming or media play). I have my display set to auto, have changed the radio to CDMA/LTE only and have disabled as much bloatware as I can. I'm now trying the battery training FoxKat recommends to see if that will help.
I know there are countless threads/topics regarding high battery usage re p880, but I didn't want to resurrect an old thread, or hijack someone else's, so if I'm wrong in creating this thread, then I apologise.Can someone please tell me what exactly this service is/does, as it seems to be the biggest problem regarding my lousy battery life.. phone just sees it as android system (pic 3) where as BS+ sees system back up service. As i have backup disabled, this is puzzling me.
Thanks in advance,
Edit: in the time it took to write this message, ive lost 14% in battery, including the time it took to screenshot.
Edit 2: Ah, now im back on PC i can type properly.
been playing around, disabling system backup service, but a new process just gets launched in its place, from key chain, to LocMgrProvider...seems as you disable one, another replaces it, all using same battery. Must i just accept, that the android system is just going to eat my battery?..like cookie monster at the biscuit counter?
If it helps, im running stock 4.0.3, freshly flashed, with F/reset, unrooted.
Thanks in advance, and any help is very much appreciated,

that's... waaaaaay too much. why are you on ICS anyway?
my suggestion is - factory reset from stock recovery (warning: your internal sd card will be fully formatted). in case you don't care about ICS, i strongly suggest JB. if you don't care about voiding warranty, i strongly suggest unlocked bootloader + custom rom and kernel. oh and also, grab better battery stats app, it shows an easier-to-understand overview when compared to apps you used

Thanks for such a quick reply.
I'll tell you the scenario, as quick as i can make it.
had the phone 2 weeks, got it on a 24mnth contract ( i know, sigh)
anyway, updated it to JB (4.1.2?) through LG pc suite, but thought the battery life seemed to be worse, so i downgraded with LG flash tool, to ics.
after a F/reset, i rooted, then F/Reset again, but it seemed sluggish.
the long and short of it is, ive gone up to JB twice, and down to ICS twice, rooted and unrooted twice, disabled a whole HOST of stock bloatware, and am still left with similar results as posted in the pics.
ATM ive a clean ICS and im at a loss as to what to do. ive been reading all the threads about improving battery, culling the bloatware apps etc before i decided to post.
as for bootloader, i will probably do that sometime in the future, when im more knowledgeable on the subject. at present, i dont want to be left with a 2 year contract to a brick
thanks again,
ps: you say better battery stats is better than battery stats plus?...will download now, thanks

interesting situation. it's strange that sluggishness persisted between factory resets and .dz flashes back to 10x version.
first off, how does the phone behave when you're not using it? is it draining battery bad? is it going into deep sleep? what are the percentages of cpu states (you can check this in better battery stats, as battery stats plus seems to be too clunky for me to read proper info)?
if it's deep sleeping properly, then yeah, the issue is with something sucking up the juice while screen is on. next off, check cpu states - if it's locked at 1.5ghz often, when you have screen on but doing nothing, it's significant info.
what i've noticed with display, you can count up to 3:30 hours of onscreen time with stock rom (this is with very conservative use of wifi and data during this period, and no heavy gaming for example) - that's around 200 minutes of on screen time, meaning you should get around 2 minutes of screen on per 1% of reduction in battery - how far are you from this result?
i hope we manage to get to the bottom of this, but i still recommend unlocking bootloader and flashing custom kernel and/or rom. you can't really brick o4x while unlocking bootloader afaik, and you've done more complex operations when switching from 20a to 10h than bootloader unlock is.
I would go the other way to be honest. If you do a full factory reset, install no apps, no Google account or anything and still get a similar problem with the battery drain then I would take the phone back for replacement as that is abnormal.
No point running a risk with your warranty when might be a hardware fault.
It's midnight here now so can't really test it till.morning now. When phone is in standby, it seems to hold.its juice ok. I'm sat here now, with nothing switched on except WiFi, screen at 23% brightness , and am just using tapatalk and I'm getting 2-3 mins per 1% screen. Less if I play in the menus. First thing tomorrow, I'll reset the phone again, before dl'ing any apps. Then I'll only download BBS and see how I get on. I'll also.monitor battery loss over night.

left phone off charge over night, and didnt even have a 1% drop in 7 hours (wifi off,sync off, data always off(dont use it)) and phone set to 2g mode

Right,
I've performed another F/reset, and rooted. Installed TB pro, and uninstalled/frozen a skew of apps/services as listed per the thread in my sig.
Installed better battery stats, charged phone to 100% took off charge, and am just waiting to see how it goes now. Would you recommend using phone as normal while BBS collects its info, or to let the phone alone for a while?

you can leave it alnoe during night to check if it deep sleeps properly, right now you're interested in cpu states option in bbs, to see if it uses too much cpu when doing normal tasks such as surfing, reading, watching/listening media etc. your goal is to get over 2 mins per 1% drain (in the end, over 3 hours of onscreen time with no heavy gaming). with those stats, your can say that your phone is draining normally, just that lg reports stupid stuff (f.e., stock roms report screen as using 20% of the battery, while in reality screen is using waaay more, the most actually)
Thanks Flying_Bear, I'll refrain from doing any more resets etc for the rest of the day, see how the readings progress and post on that tomorrow, after overnight analysis.
This piece of one of your previous posts just stuck in my mind:

TBH, from everything I've been reading on it, it kind of scared me off the subject, but to see you say it was less complicated than what I've already done, has got me to thinking.
The biggest thing for me at the minute, before considering that, it to rule out faulty hardware. At least if thats the case, i still have warranty intact.
Is the performance increase really that noticeble after flashing custom kernels/roms?
Thanks again for your time,
Sun
no.
apart from everyone here praising custom roms and kernels, DON'T flash a custom rom, when you are concerned about battery.
the best rom out there regarding battery life is by far a stock rom, be it 4.0.3 or 4.1.2.
the worst thing about the custom roms is WiFi. with stock i was able to let WiFi run through the night with less than 1% loss per hour.
on every custom rom my battery needs at least 5% per hour for WiFi, but most of the time even more. its just not useable.
shortly followed by 3g network, which has a much bigger battery drain than stock, too.
i am on CM and different kernels for some month now and i consider going back to stock, because i want to leave WiFi on in the night, otherwise my phone eats up my 100MB free 3G traffic way too fast.
BUT...
the reason for your battery hungry phone is not the ROM, the kernel or the phone itself.
your battery drain is absolutely absurd for stock ROM and can only be caused by badly programmed apps you have running.
OR:
you have your phone relatively new and play with it EVERY FRICKIN MINUTE, which would be an explanation, too.
you said, you were able to watch a whole 2h movie with only 23% loss, that sounds like the stock ROM i know. on custom you would lose around 50% for this. but when your phone loses battery when you "play with the launcher", you maybe have installed a 3rd party launcher, that eats your power, are using facebook/skype/whatsapp/(insert any other badly coded program, that has no push mode), or have just fiddled with the developer settings a bit too much.
Because you noticed your battery drain with 4.1.2, too, then i suspect a badly coded app. these are the reason for nearly every battery drain (and the reason for wakelocks, too) apart from bad drivers in custom kernels, like the WiFi desaster all the custom rom users have here.
I think the only reason I would consider custom roms, is a performance increase.... If it wont give me one, then I see no point in going down that route.

when I took the original screenies, in OP, I didnt really have much in the way of apps on it. I'd not long before done a clean flash, then removed some of the bloatware that came with it.

yeah, it handled a movie quite well, I was quite pleased with this. When i said messing with the menu, I just meant exploring the phone; no custom/3rd party launchers, no messing with Dev stuff.
At the minute now, the only extra apps on my phone are XDA Dev app, tapatalk4, BBS, TB-pro and root uninstaller pro.
Oh, and can I ask.... aside form the ability to "pimp" your phone out, or the extra customization, is there any benefit to flashing custom roms? As it cant be for better performance....
thanks

your battery drain is absolutely absurd for stock ROM and can only be caused by badly programmed apps you have running.
OR:
you have your phone relatively new and play with it EVERY FRICKIN MINUTE, which would be an explanation, too.
you said, you were able to watch a whole 2h movie with only 23% loss, that sounds like the stock ROM i know. on custom you would lose around 50% for this. but when your phone loses battery when you "play with the launcher", you maybe have installed a 3rd party launcher, that eats your power, are using facebook/skype/whatsapp/(insert any other badly coded program, that has no push mode), or have just fiddled with the developer settings a bit too much.
Because you noticed your battery drain with 4.1.2, too, then i suspect a badly coded app. these are the reason for nearly every battery drain (and the reason for wakelocks, too) apart from bad drivers in custom kernels, like the WiFi desaster all the custom rom users have here.

yeah wifi can drain too much, but i had almost same stats on custom as on stock - 3-4% per hour if wifi is left on, with sync on and push notifications and blabla. you've got things going great if you have 1% per hour with wifi on.
lg has crammed up a whole lot of **** inside their stock rom - apart from useful stuff like proper mhl drivers, quickmemo, nice gallery & video apps, it's bloated to hell - mlt logging, ****ty launcher (imo), widgets that only work on stock launcher, "smart log service", RIDICULOUS throttling etc). you can root and uninstall most of these, but even then you might not get what you're looking for.
my best onscreen time on stock 4.1.2 20a/20b was 3 hours 3 minutes. that's with conservative use of wifi, 3g and almost no gaming. on custom rom & kernel, today i pumped out 3 hours 37 minutes, and was on 17% battery, when i plugged it in in order to recharge it. that was an obvious increase for me (keep in mind there were custom rom/kernel combinations that had me pulling barely 2 hours onscreen time).
you need unlocked bootloader for custom kernels, and say what you say but proper kernels ARE battery savers and performance enhancers. stock kernel has for some people insane issues with baseband_xmm wakelock (for me it was rediculous, 6% per hour drain when not using a phone and no deep sleep at all) and wipes didn't help with that; only custom kernel fixed it. it has RIDICULOUS (for emphasys) throttling effect, slowing your cores down to 1ghz each when battery hits 43 degrees celsius (which for me was around 20 seconds of normal usage on a hot day outside), which leaves you crippled if you're planning on doing any complex action with your phone.
alternative is - unlock bootloader, check custom roms and see if you like'em (Zaiben is f.e. debloated and improved stock, something OP might like, or he can go cm, or carbon or any other if he prefers custom features). if you don't, it's easy to flash a .kdz file back.

Hi Flying_ Bear, can you pl confirm what combo of rom and kernel is giving you 3 hr 37 min of screen on time and which ones to avoid (ones that gave you 2 hrs)?
Carbon rom 4.2.2 version with iodak v7 had the best onsceen. Id say stock was worst, 2hrs 45mins of onscreen with no gaming and low brightness, with stock kernel
Hello everyone,
I switched my 16 months old 4x to CyanogenMod 10.1 about 2 months ago, and updated to 10.1.3 about a week after the release. About a week later, I had my first problems with rapid battery draining. I have switched kernels thrice, now running the most recent optimus prime for CM, and have tried fiddling with the values TricksterMOD provides, but I haven't found a way to get any decent battery life out of the device ever since. Last night, the battery drained 50% in about 12 hours of non-use (phone was left with display off in my jacket pocket, and that's not even the worst drain I witnessed in the last two weeks.
I'm running BetterBatteryStats to get a clue about the origin of this drainage, and can see that my device seems to me awake far too long when I'm not using it. At the moment, I'm looking at 44.6% awake, 55.4% Deep Sleep after 2.5 hours of not using the phone once (I was driving home from work half of the time). In "Kernel Wakelocks", I see "wlan_rx_wake" with 21:03 minutes on top, in "Partial wakelocks", the highest value is 20 seconds for "AlarmManager".
I have the usual suspects of communication/networking apps - Facebook (set to 2hr update), Google+, K-9 Mail, WhatsApp, plus AndroidWeather (set to 30min update) - and news apps which are allowed to send push messages. I use wifi, but no bluetooth. I never watch movies, play games or listen to music with my phone.
I have attached a BetterBatteryStats log from the 50% drain in 12 idle hours I mentioned. View attachment BetterBatteryStats-2013-10-17_092335401.txt
Can anybody give me any pointers as to what I going wrong here? I really would like to use my phone without having to plug in the power supply every few hours. If you need any additional information, I'll gladly try to provide it.
Anyway, thanks in advance for any help.
Cheers, Pit.
only 3 letters. O M G ! this battery report just made me like this face here
u cant flash kernels one after another. there are bugs this way. dont all kernels use the same names for files. leftover files will cause problems. do the whole procedure. go to recovery , format data, reboot to recovery and install new rom

You mean you cant flash Android roms one after another. You can freely flash kernels one after another without wiping anything, Its completely modular.

Not sure about the battery drain, it could be caused by a kernel, but its not because hes flashed multiple kernels.
some background:
Android kernels are packaged into boot.img's (these .imgs can be placed in .zips with instructions on how the custom recovery should handle flashing it) Inside a boot.img you will find a zImage (kernel) and a initrd.img (This stands for initial ram disk, its simply a basic file system that the kernel mounts, containing mainly scripts that handle mounting all the necessary partitions etc, then handing control over to Android. )
The boot.img is stored in a emmc partition (/dev/block/mmcblk0p*). When you press the power button, the bootloader is initialized , it then powers on necessary hardware devices, the bootloader than pulls the boot.img from its partition, extracts it and boots the zImage(kernel), which will start initializing less necessary hardware, but mainly mounts the initrd.img and runs the containing instructions.
Bootloader -> Kernel --------------------->
.........................Initrd.img-> ........Android
To move back on track, the zImage and initrd.img only operate within RAM, they only lie in emmc when they are achieved as a boot.img. When you shut your device down, nothing from the kernel persists in the next boot (maybe /proc/last_kmsg ), this is why you dont need to wipe anything on your device between kernel flashes.

Thanks for clarifying that; it saves me some trouble.
Does the BatteryStats log give any indication as to why the phone is awake half of the time?
Cheers, Pit.
Dont know, but maybe O Prime is one of these kernel which hides the xmm baseband wakelock.... that would be the missing awake time in your log

Is there a different kernel you would recommend I should try out? I selected the OPrime because it claims to be focussing on stability and battery life instead of raw power.
Furthermore, what would the baseband wakelock tell us in terms of how the fast drain happens?
Cheers, Pit.
Hello all,
just to try it one more time: is there any way I can get decent battery life out of CM10.1.3 on my 4x? This is my profile from today, where I unplugged my phone from the charger around 7:30 a.m. and didn't use my phone thereafter until 5:30 p.m. where the phone was down to 38% already (stats taken around 8:30 p.m.) . The governor is set to conservative and the max frequency to 1.1 GHz, which already makes the UI a bit sluggish. The other settings are unchanged from above.
Secondly, if there really is no chance of improvement under CM10.1.3, which ROM (and kernel) would you suggest for my phone, so that I can at least get a full 24 hours of battery life when I'm not using my phone most of the time?
Thanks in advance, Pit.
Format SD card and wipe everything before flashing new ROM. When I say everything I mean : catche - dalvik - format system - format sd card (sd card is 11gb internal memory of device and external sd card is your inserted sd card). Try latest liquid rom i have good battery life with its stock kernel.

Hi everyone,
well, that was a bust. After spending the better part of a day formatting and installing over and over again, I'm now running CarbonRom [20131023] - and having the same battery problems as before.
I tried LiquidSmooth (2.23), but I never got it to work properly; after installing I always got "application someName was teriminated" every few seconds (while the Play Store app was redownloading and reinstalling my apps, but also when I tried to activate SwiftKey, which calls the settings app at one point, which abruptly quits before I can type in anything. I then tried
ParanoidAndroid (3.99, which I didn't like UI-wise)
and SlimBeam (1.9, where the Google apps I downloaded as stated would install fine, but then not appear for some reason - at that point I didn't spend much time trying to fix it, because I was already fed up with it all)
before finally installing CarbomRom, which worked fine. Thus, after downloading my apps, I tried out my battery again. I unplugged the phone, turned the display off, and went shopping for about two hours, touching the phone just once for a few seconds.
The result is again about 30% awake time during these two hours, losing 10% battery in the process (BetterBatteryStat included). That is pretty much unchanged from my experiences with CM10.1.
What am I repeatedly doing wrong that I don't get halfway decent battery runtime out of my 4x (which used to run fine battery-wise for a year when I used the original LG firmware (which had other issues, but could last 36 to 48 hours, depending on usage? As I don't see hordes of 4x owners throwing the device against the wall in frustration, I must do something other don't. But I haven't got the slightest clue what that might be.
I will try PACman (nightly 20131021) next, but if anyone has any pointers, please please help! I'm running out of ideas.
This was my procedure, by the way:
Reboot into CWM
Format system, cache, data, sd card
flashing ROM
Rebooting
after bootup reboot again into CWM
add the Google apps
reboot again
After bootup, reboot again into CWM
just to be sure, reset to factory defaults
reboot, connect with Wifi and Google and start redownloading the other apps
Frustrated greetings, Pit.
Hi again,
PACman is even worse. First off all, the UI is laggy as h*ll; sometimes, it takes more than two seconds for a button touch to be recognized.
That would be somewhat tolerable if the battery life was better. But in 2.5 hours of leaving the device lying idly on my table (display turned off), more than 50% of the time, the phone was active. BetterBatteryStats are again included as an attachment; perhaps someone can find out what the problem is with them. At least, this kernel doesn't hide the xmm_baseband wakelock, though I have no idea what that means whatsoever.
This is getting ridiculous - is there really no way to get the phone to last more than ten hours (doing nothing with it - when I use it even for occasional browsing/e-mail checks, it's way less than that) anymore? Why is no one else having problems on that scale?
Typing this post cost 3% of my battery. And I'm typing it on my computer, not on my phone.
Depressed greetings, Pit.

Thanks, for the info, I will investigate that, though I haven't found this "wifi update of demetris" on first Google try yet, just recommendations what to do with your WLAN router and PC settings.
But I my second-to-last try - where I was out shopping - the wlan_rx wakelock wasn't the problem, rather the xmm_baseband wakelock, where I still am clueless as to what that means at all. I fear that getting rid of the wlan wakelocks wouldn't help my general problems, just the problems I had at home last night in my last try.
Furthermore, if I can use the phone only by carefully switching off and on wlan manually whenever I leave the house, the phone will become pretty much useless to me. Yesterday alone, I forgot switching wifi back on twice. That way, either notifications would go through mobile data connection or not happen at all.
I will reflash my device again this morning - as the PACman UI lags are unbearable for me - and see what I can do about the wlan drain. I cannot reconfigure all the wifi networks I connect to, as some of them aren't mine to configure.

I tried that earlier today, and the LiquidSmooth 2.9 (Android 4.2.2) installed fine by your instructions. But it didn't help at all with the battery usage. Phone is running on conservative governor limite to 1 GHz, and I even tried the Broadcom Wifi Update mentioned here earlier (otherwise, I'm on the LS standard kernel).
It all doesn't help, the BetterBatteryStats are still full of wlan wakelocks (even though I switched to static IP as someone mentioned that might help). Result: 10,8% battery drop per hour of leaving the phone with display off on the table.
Before I flash another ROM for the 14th time this weekend, I will collect some results with wifi turned off. Not that that would be a feasible option for me, but I want to get to the bottom of this.
Cheers, Pit.
Hey guys
I already posted my problem in the thread related to LineageOS, but since the issue couldn't be solved I want to try it this way.
So what is my problem?
While using my phone it gets very hot. According to Powerful Monitor the CPU gets up to 65 °C and battery up to 35 °C, while under load. Besides this my battery goes down rapidly. So watching 10 minutes of YouTube sucks up 8-9 % battery. Just a plain normal video.
What is my setup?
I9295, running LineageOS 14.1-2017-06-06-UNOFFICIAL-jactivelte, OpenGApps 06-07-17 nano, only apps installed manually are GeekBench, Powerful Monitor and YouTube. Baseband is I9295XXUDOB4 (German unbranded DBT). I bought a new original Samsung battery and currently using it. So it's basically stock LineageOS.
What have I already tried?
- flashed stock firmware (all available for Germany that are unbranded). With and without erasing NAND, with different Odin versions. Last time I flashed I used Odin 3.07
- different batteries: the old ones the phone came with (bought it used), the new one I bought separately, a new one from PowerCell with higher capacity (2900 mAh)
- different phones. I have a second I9295 from a friend, that worked definitely without any issues. Same problem.
- different custom ROMs: now I'm running LineageOS, but I also tried CM13 (20161228), CM12.1, MIUI and Super WizCyan (everything from xda)
Is it possible break something ciritcal when disassembling the phone? Both phones came with broken covers for the USB port, so I opened it, but only removed the screws and the mid-frame (?) and replaced the cover. Nothing was damaged, at least I was very carefully and didn't see anything that looked suspicious.
Another very strange thing I noticed:
If I use the phone a lot (lets say 30 minutes, so almost 25 % battery!) and after that the phone is not in use for an hour or so, the battery goes up for up to 7-8 %. How it that possible?
I really have no idea what else to do.
Any help is appreciated.

Hey there. Well, there are tons of possible reasons why your phone acts like that. My modest opinion is that you have some sort of wakelock active in background. Install both Wakelock Detector and Gsam Battery Monitor, grant all the permissions and let it obtain data for some minutes. Than look at the results, and check if there's any Wakelock active. If instead Gsam shows an excessive consume by the kernel, try in terminal the following commands:
Code:
su
setenforce 1
setenforce 0
Then see if there's still the drain (you have to wait some minutes).
If it still doesn't work, I'd advice you to update to the latest stock firmware (doesn't matter which Country, just select a non-branded one), reinstall LOS again and verify if with nothing installed you still get the battery drain.
Anyway, IMHO it's not an hardware related problem, even messing up with the components this shouldn't happen. The only hardware fault could be the battery short-life, but 1st you said you just replaced it, 2nd it would not justify the thermal overload. Let us know
Thank you very much for your answer. I'm quite short on time next days but maybe I have a few minutes on sunday.
On the matter latest stock firmware: already tried that on monday, still too much battery drain, but I didn't install LOS till now. Maybe sunday.
But still thank you
Finally I found some time to try your suggestions
I skipped the part of trying it on the old setup, so I flashed everything new with latest stock(UDOB4-DBT, not the last one but still Android 5.0.1), then TWRP 3.1.0, after that LOS 14.1-20170606 and OpenGApps 7.1 nano from 17-06-06. Only apps I installed beside that are GSam Battery and Wakelock Detector. Root activated and granted where asked and needed.
Here I uploaded the pictures I took from GSam Battery.
So what seems strange to me:
- why is Phone Radio used at all? I don't have a SIM card inserted...?! It's on a very high level, even if the screen isn't on.
- The battery gets hot quite fast. If it's not in use, everything is fine. But as soon as I use the phone it gets hot.
- As you said: kernel usage seems quite high, tried to install "Terminal Emulator" and executed the commands - no difference.
According wakelock: where do I check that?

Sorry for the delay, but if you do not quote/reply me I cannot see the message cause I'm not extremely active on XDA. Anyway...
- Phone Radio is used even without SIM, at least in TouchWiz, dunno in LOS, but it looks like so. The only way to disable it is Airplane Mode.
- It gets hot due to kernel usage, what I still do not understand is why it does so.
- Those commands where the only commands I think could be useful in this case (they set SELinux Permissive/Enforcing)
But if you say you get the Drain on TouchWiz too, the problem is serious and there's a (little?) chanche it would be HW related.

No need to apologise, you're doing this in your free time...
Besides that, I wasn't at home all week, so I couldn't try anything even if you had answered.
So, how do I get the kernel to calm down and stop draining my battery? I mean, I didn't install anything besides clean LOS and GApps. So what could lead to so much kernel usage? Are there any further information that could help you?

The situation is very weird. Let's analyze.
1) TW/LOS doesn't matter. Battery drain in both
2) No apps installed which could cause wakelocks
3) Battery SHOULDN'T be the problem
4) The drain is recognised as kernel "usage", though it couldn't be real 'cause of point 1
5) Neither Permissive nor Enforcing SELinux mods helped
At this point it doesn't look so much a SW problem, but more an HW one. About:

Well, sometimes the discharge happens so fast the battery doesn't calculate the remaining capacity so well, and after some minutes the real charged cells are more than the "estimated" ones. It would explain the "goes up" of the percentage, but still not the drain.
It's very strange and very rare, but there's an infinitesimal possibility that the thermal paste went to the hell. And in this case there's not that much to do.
That's pretty pessimist though. I'd advice you to format everything, reinstall the latest stock TW and stick with it, and if it still doesn't work, try with some apps like Greenify and ForceDoze (this one works just with 6.0+) in order to at least TRY to reduce the drain.
I'm sorry I cannot help you more, if anyone has some suggestion, please let us know.

Next strange thing is, I have two S4 Active devices, both have the same problems. Am I just unlucky enough to get two broken phones?
Still, the device I got from I friend was ok the moment he gave it to me. He said battery lasted for only one day, but that would be ok. So it has to be something I did with the phone.
Youre are not alone. My Phone was/is also getting hot.
Then I did a full wipe ( format also internal memory partition!)
I'm current running cm13 (CM13 (20161228)). Batterie works now / normal ok / 1 / 2 Day s ( no great usage ). But when i telephone with someone it's getting hot in 15 min. Modem Version is I2995XXUDPB3.

Have you flashed any custom ROM? Try downloading an entire stock firmware for your country / carrier from sammobile and flash through odin 3.09 and check. The S4 active generally gets hot on usage but should not get very hot. You can also try using powersave mode that limits cpu max freq and prevents heating. Battery on normal usage shoukd last for little under a day to a day with normal usage unless you are using data (otherwise set mobile networks to GSM only which saves battery and reduces heat)

Normally i have seen issues flashing through odin 3.10 and prefer 3.07 or 3.09. If the firmware flashed correctly and you do not have any issues then it should be fine.
CPU temp of 65% without powersave mode is fine and watching youtube videos does consume battery. Try a different charger / cable combination as that too can have issues. If the battery gets charged quickly (on stock kernel under 2 - 2.5 hours from 0 to 100) then there is definitely an issue with the charger and it will drain quickly too.

I tried 3.10, 3.12 and 3.07 so far. Not successfully. Tried 3.09 now, we'll see.
I have a Sony Xperia Z1C as comparison, YouTube needs maybe 1% for 5 Minutes.
Cables/Chargers shouldn't be the problem. I have the original Samsung, also cable. Charged to 0 to 75 % in 90 Minutes. Same with cable and charger from Anker. So should be fine?
So no new ideas?

I have no idea too but i have the same Trouble with mine BUT I'm still using the original Rom and didn't flash it. So maybe it is an Hardware issue.
My Battery is getting old, yes, but it is the third one. The Phone gets hotter than in its first years.
I hope you'll find a reason!
My i9295 always has been like this: 1 minute on-screen time = 1% battery loss. So this basically is a 2 hour phone... Stock or custom rom didn't matter. A friends i9505 used a lot less power, therefore I assume that the LCD (instead of the S4's AMOLED) is the problem.

Nah, why should it? There are a lot of i9295 users that don't have any problems.
