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.
Is it just for me? After a full charge the screen on time is about 2 hours.. Tried cm11 and other custom roms without luck.. When i bought the phone and wasnt on KitKat the screen could pass 4hours. Huge different!
In battery info the only program that drain the battery is the system it self . any tips?
check your rom and kernel, any overclock setting is active.
check battery usage to find what drain your battery.
Mine have 4h30 - 6h screen on (just wifi, without mobile data)

No overclock set.. Just the system thats drains battery..
@colors Battery life isn't as good as I think it could have been but at completely stock and with nothing on the phone the phones battery is pretty phenomenal, an idle Z1 will stay on for over a week, infact i've seen some phones with 19 days before now quoted within stamina mode.
Just took a pic of one in my workplace and it's saying just over 19 days, that's not too bad for a phone which is always on and capable of receiving apps via wifi (see picture attached)
I know that 19 days is excessive and no one here is ever going to get anywhere near that or even a week, unless you don't use the phone, the problem most of us face is the apps that we use and their footprint on our phones, affecting battery life and performance.
Take a good look at your apps and what you use and see what you could do without or what could be affecting battery.
A clean install will usually give you great battery if theres nothing on the phone to slow it down, eliminating apps one by one might seem mundane but it's key to great battery life, after a while you'll learn whats bad and whats acceptable.
Using the likes of CM11 could cause even greater battery drain as it's all custom stuff, not to mention that some things within the system aren't working as good as they could be, there is still a lot of work before things are perfect, double tap to wake for example is a feature which could cause massive drain.
Always perform a full wipe and don't restore anything via recovery, leave it as a bare rom until you can verify the ROM you are using is without issue.
Hope this helps
ever since i have updated to lollipop firmware, i am facing strange overheat and sudden battery drain problem on my c6902. it does not happen always but sometimes and restarting fixes it. and also faux clock shows continuous use of first and last core of cpu. do you have the same? any help?

did you did a factory reset after install?
Mine is draining so fast. Even when turned off. I didn't do a factory reset after install because i dont want to lose any data. My maximum charge is 11% after 3 hours. I dont even know if i can flash anything because it's lowbat.
for me is ok. the battery life is good, and i got overheathing only when i did a first start after i installed it. try to install kernel aduitor and see if all governors are on "ondemand", and if all freqs are ok.
reinstalled and did everything as it should be but stll gets hot and quickly drains out battery sometimes not always
without using battery drains to 50% in few hours
Possible Solution to Over heating after lollipop install
I had the same issue of Xperia Z1 Compact over heating after lollipop install. I backed up all my data using Sony Companion and reset my phone to factory. After that my phone is working like a champ. No more over heating and battery life last over a day and half. Hope this help.
guys,
I had the same issue and im thinking to downgrade to kitkat for real
I have tried it.. No use. It will heat up in kitkat too. Really annoying.

How old is your device? Looks like the battery is having issues. Or maybe the motherboard is supplying over current to the processor.
Its about 2 yrs old. But the heating started just after lollipop update. Before it was ok, no problem was there.
having the same issue since update to lollipop. really annoying thing. battery drained in an half hour down to 89%. that just cant be normal.. phone is not rooted or anything.
Hi,
For those who are rooted and with a custom kernel, I have faced the same problem recently and after playing a bit with CPU configuration on "Pimp My Z1" app it seemed to work again.
First thing I did was reboot the device, that way I was sure that no app I've opened was draining my battery.
Second I opened the "Pimp My Z1" app and changed the configuration of CPU to:
Maximum: 1958MHz
Minimum: 300MHz
Governor: lionheart
Click to expand...
Click to collapse
Also set the max clock of GPU to 320MHz.
As for the power management config, I've set this way:
Multi Core Power Saving: Aggressive.
Hotplug Driver: Intelliplug
Eco Mode: On
Power Suspend: On
Click to expand...
Click to collapse
Today I'm with 82% battery but with 59 minutes of screen on time (~70% brightness) and some more of music playing. Also using Stamina Mode. Heats a bit, but doesn't show any draining symptom.
If you still face overheating problems, I suggest downloading the Greenify app and hibernating many apps. That worked for me on S4 when it was with a similar problem.
All the best,

I have the LG Leon for MPCS w/ 5.0.2 root-TWRP. I began experiencing this after flashing a sound engine mod. I also noticed my charging port pin was bent slightly. Another possibility was changing CPU gov-I/O-min. freq.
I flashed mod remove zip, then restored from Nandroid prior to, and fixed pin. Still had it.
BUT: I kept my phone on top of my AC unit vent for roughly 13 hours while it was on & plugged in, set brightness to night mode, 15 sec time out, and disabled daydream.
PROBLEM GONE.
Also set CPU back to reg. settings.
CPU has been steady 28-30 deg. C all day.

Hi guys, long time since I've been on here.
I have a S4 i9500, and I was having mega drainage issues. I installed Novalaunch, and disabled the samsung touchwiz crap - battery usage is SOO much better already. I have had lollipop for a few months now, and I did factory reset it, twice, and install all the apps manually via google play. It got so bad, that i HAD to run my phone with power save on ALL THE TIME, and even then, it would be pretty hungry. the other day, I ran it on full power(1.6ghz) and it chewed 40% in around 1 hour. All I was doing was had Pandora music on.
I have a tool called 'Cool Tools', and I monitored the IO activity bfore, and it show pretty high utilization all the time, even with the screen off. With Novalauncher, its hitting rock bottom(low), even while using it..
Its soo good now, to give you an idea - I charged my phone last night(around 9pm), and restarted it and unplugged the charger. I ran it on full power(power save OFF), over night, with data on, and it only chewed 15%. MASSIVE difference. I'm at 60% now, and I've been running Pandora for at least 3 hours now, and using some other apps as well. Its been 14 hours or so already.

Even I faced fast battery drain with Touchwiz launcher.
Now running custom ROM and seeing that CPU usage is lesser and battery stays longer.
However, nothing can beat Kitkat's battery usage. Lollipop, according to me, is a battery killer wrapped in material design for disguise.
Xperia z1 battery drain issue or problem
I FOUND THE MAIN CULPRIT FOR BATTETY DRAIN AFTER 5.1.1 LOLLIPOP UPDATE. Its the overheat control app. As you all may know that after first update from jellybean 4.2 to kitkat 4.4, the phone tends to get overheated while multitasking. Thus overheat control app eats up the battery and drain it when the phone starts getting hot.
I REQUEST ALL THE DEVELOPERS TO CHECK IT AND PROVE IF I M WRONG.
I m sure that Google will find the answer to the battery drain issue fix in overheat control app.

I'm coming from a OnePlus One. Unfortunately, I can't find reliable BLP571 replacement batteries in the U.S., so I purchased a new OP3t.
On the OPO, I have been running custom MM and N-based ROMs. When the OPO (currently running Nougat 7.1.1 on TugaPower 2.1) is sitting around doing nothing, I typically see my idle battery current drain at around 9 uA to 14 uA and Wakelocks around 10%. Of course, when I turn the screen on, these jump up.
On the OP3t, I have tried running both OOS 3.5.4 and the new TugaPower 4.0 (which is based on Nougat 7.1.1). When the OP3t is supposedly doing nothing, I saw an idle current of around 85 mA on OOS 3.5.4, and around 35 mA on TugaPower. I didn't check the Wakelocks on OOS 3.5.4, but the Wakelocks on TugaPower are around 93% awake time (!!!!).
When I wake up in the morning, the OP3t is down to around 75% battery. For reference, my OPO used to be around 98% overnight when the battery was new. Even now, my ancient OPO with a nearly useless battery is around 85% for the same overnight time period.
What can I do?
3.5.4 actually has drain issues, try 3.5.3
Even after the annoying wake-locks and the random battery drain that just happens because why not... I still manage to get 5-6 hours of SOT, I have managed to push it till around 9 hours if I keep the Bluetooth and data off; with Greenify and using the aggressive doze it has helped but I don't get any notifications until I turn my screen back on.. Which is fine with me, as I get texts and calls. It's much better than the nexus 6 and the galaxy s4 which would struggle to even get 4 hours of on screen time. There are plenty of people raising issues about battery life on the OnePlus3T even though its probably much than your last device. XDA also has plenty of threads already created talking about the same subject.
Edit - I'm on the latest nougat update 4.0.1
the 3T or OOS doesnt have any drain or bad battery issues.
the problem is user/user-app based.
sort out the app which is causing the problem.
I just made a post to a similar thread. It seems the battery issue is hit or miss. At any rate, please check my post here: https://forum.xda-developers.com/showpost.php?p=70581453&postcount=9
Let me know if this helps you out. Look forward to feedback.

You stole my thunder.
Just kidding, but you're absolutely correct. I'm waiting to get my OP3T and then I will write a tutorial for users to help them out with the battery. Those 2 apps will be in my tut along with a few others that are helpful!
Weird, usually my phone, while idle of course, drains by 1% every 2 and a half to 3 hours. During use while im not playing games or anything im using pixel filter. Most time ive gotten is 9 hours 32 mins screen time. Im on 4.0.1 not rooted. Just uninstall apps u dont really need like amazon, youtube, facebook, tumblr and so on and use Firefox web browser. Firefox has background play for YouTube or any other audio source so you can stream music on Spotify soundcloud or whatever you want. I basically rely on Firefox for all internet things as if my phone were a PC. Saves time and battery because with 6gb ram my browser never slows down or reloads. Firefox is also really nice in the background consuming only 10mah every hour when not active or streaming audio. Cutting down ur app count will allow your device to doze longer, fetch less data and it certainly drains far less. Also if you're into this sort of thing, boot times are much quicker too.
Edit: sorry for the unedited massive paragraph here.
Another Edit: Make sure in case you want to use battery saver mode while streaming music to toggle Firefox to have unrestricted data usage in the data saver menu.
Check the link in my signature. My drain wasn't quite as bad but might help you figure it out. Good luck!
Thanks, guys! Greenify + ForceDoze seems to be helping a LOT! I'll need to let it run a few days to see the the real-world numbers.
I am having a problem adding apps to the ForceDoze Whitelist, though. Is that a known issue?

I've found that the whitelist appears blank until you add or remove an app, then the whole list will appear.
For me at times something appears to kick in in the background causing the CPU to spike and the phone to heat up. I can't figure out what it is though. When this isn't happening the battery drain is virtually zero and the phone flatlines overnight ,when it kicks in,the battery loses about 10% an hour on idle. I think there might be faulty drivers or something in the ROM causing this?! It's not apps as it happens to me on a completely debloated ROM with no apps. This is on Lineage and OOS. I've never seen this before on the phones I've had.

OOS 4.01 - I am experiencing exactly what you describe at 12%/hr and I have done literally all of the suggestions here. I have greenify, force doze, turned off location, disabled swift, did a factory reset and installed only 1 or 2 apps- and still I can watch battery drain with:
4 hours off charger and down to 44% with:
Kernel (android OS) 42.5%
Android System 33.7%
Google Play services 2.4%
Blah...Blah... (much smaller %'s)
What the heck could be causing this kind of drain? It seems to flatline when not in use for a while...
thoughts? Love the phone., but it is not usable like this....
4.0.1....No battery saving apps..

Hello,
I usually use Greenify Paid Version + Amplify Paid Version but only in 6.X roms in 7.X Xposed isn´t released yet....
Do you recommend use Greenify + ForceDoze (I never heard about this app) even without Xposed?
Thanks in advance.
I am still struggling with battery performance on my new OP3t.
I am running TugaPower N10 (LineageOS 7.1.1) + Better Battery Stats + Battery Monitor Widget + ForceDoze + Greenify.
While my wakelocks seem to be pretty short now, my lowest average current drain is 35 mA. For reference, my old OnePlus One had a lowest average current drain of 7 mA, or about 5x more on the OP3t.
My battery meter reflects the higher drain.
I have the same apps installed, maybe even some less.
Looking for more assistance ...
I'm on 4.0.3 OOS and using Franco kernel, 2% drain during all night, 5 hours of screen on time and still 56% battery, check what is wrong with your apps, or move from Lineage to OOS, is simply better.
EDIT: I'm not using any app like ForceDoze or Greenify
I'm not dissapointed.
Rooted Note 8/FD 64gb with exposed installed.
Fully charged. From 100 to 90 took only 25 minutes using phone normally with wifi.
And also it charges too late. From 33 to 63 took 45 minutes.
And also scrolling chrome faces lag also playing simple games like "Dune"
Is all of this normal?
Anyone else facing this problem?
I know the warranty is void, but garanty too?
Anyone know a fix?
+ I used smart switch and sent all of my note 4 apps and data to this phone.
and let me add that I played it in game mode so its expected not to lag.
It even lags much more when I start recording...

Do you have any other idea?
I think You should flash stock firmware with Odin and leave it on Your phone for a couple of days and see if Your battery gets better.
Also, You should expect around 4 to 6:30hr SOT on Note8. That's the SOT I get and it's usually with low/medium usage.
And on my Xiaomi phone I get 10-12hr SOT with pretty high usage.
Samsung phones don't have the best battery life but I guess it's enough for most people + You can use quick charge.
So, do these things:
Flash stock firmware with Odin.
Use Your phone for like 3-4 days(OS will optimise itself to Your usage).
Take screenshots of how much SOT You get every day and see if it improves during these 3 days.
Tell us about Your results and then we will be able to tell You if Your phone is normal or needs repair .
I know that xposed v88 was bad for n8 regards battery drian.
I have installed v89 xposed.
And it looks much better than older versions.
I know it sounds stupid, but have you checked for viruses?
battery drainage and data consumption are sometimes signs that you have unwanted software or apps installed on your phone.
Do the following steps and see if it works:
1. Boot your phone into Safe Mode.
2. Search for the virus (For this, go to Settings > Application Manager and tap the Downloaded apps section. In most cases, the virus is a third-party app, so look at what you’ve downloaded over there and see if there’s anything suspicious.
