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..

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.
Hello!
Please allow me to introduce myself - I am a long-time xda forum lurker, who has not had the chance to post due to the fact that I am neither an expert, nor have had any questions that weren't covered by a simple search.
However, the day before an interesting thing happened to my P880. Without updating the software, due to the fact that my operator does not support it, battery life suddenly plunged significantly. In fact currently when charging, it discharges faster than it charges. So the only way to use it is to turn it off, charge it and then use it for a couple of hours.
As I said my software is stock and I haven't changed it for almost a year since I got the phone. It's version is "LG-P880-V10h-NOV-19-2012" with 2.6.39.4 Kernel.
That is what makes this issue even more interesting in my opinion, I cannot find a cause for it.
I note that the phone is warm to touch, so something is wake-locking it. However I am not an expert, but I will do my best to provide additional information if I can.
Thank you very much!

First of all download BBS and see what is keeping your phone awake. If you say that the phone is always warm than that wakelock seems as logical culprit. Something is keeping your phone stuck on high frequency and keeping it from deep sleep. Use BBS, you will know more after that..

The awake time is 9%, similar to what it was before, however the prone has been woken 872 times by System(radio). At the moment the phone lasts for 3 hours at most, while being charged at the same time.
Check your radio settings,maybe it is connecting to network all the time. Also you can freeze it..

I force stopped the radio from the applications, and I had tried that before as well, however there is no noticeable difference, I can still see % drop by the minute.
Maybe it is battery malfunction..

Issue is resolved by removing the external microSD card.
Now that was unexpected...
I haven't tested it with another SD card if the problem was in the card or in the phone itself.

well, there's your problem. it was the mediascannerservice on android. the thing that scans the storage for media files for your music player, video player etc. it will go insane when your memory card is corrupted or damaged, which looks like what has happened to your memory card.

Hey everybody on d XDA Forum. I recently sold my Xperia U for this S3 LTE. I receive uograde to 4.3 but after i upgrade the battery life very bad. I need a way to solve this. If not i go back to xperia u and no more samsung for cause same thing happen to me with galaxy y
I noticed too an higher battery drain since the update... I tried to freeze all samsung bloatware, to block system sync but it's nowhere near the screen time I could get under 4.1.2
See multiple posts and see 4.3 battery post above this one .
It's a problem many people are facing...
Well, this a problem apmost every smartphone user is facing nowadays.While Smartphones have gotten better and faster with the passage of time, the battery lives have gotten worse.
But male sure to turn off Wifi,Bluetooth,GPS,3G/LTE when not using them.
Using apps like Greenify and battery doctor may help improve battery life as well.
I oppened a thread about this battery issue. It seems like this drain is given to samsung blot apps, http://forum.xda-developers.com/showthread.php?t=2615463
Battery drain caused by different issues different apps installed by different users. Install greenify and wakelock checker and u will know what apps are using or running in the background. For me it was mx player once. Then i reflashed another rom it was facebook and activesync email. So trial amd error urself. Thousands are saying battery is better then 4.1.2 so cant be the rom.

Hello, I've been looking for solutions to this problem for a while now. Basically when my screen is on and system is awake the top part of my screen and backside will heat up to about 50C, it burns on the touch. Betterbatterystats gave a temperature of 52C and avg of 50. Needless to say, my battery also runs out very quickly like this, also dropping about 5% an hour when the screen is off.
Another thing I've noticed is that SDcard takes 25% of my battery usage, and when I go to storage settings, it will infinitely calculate. I mounted my storages and chkdsked them, fixed some corrupted files but the problem still persists. The only storage I haven't mounted is the internal storage, which I'm unable to do. I can't seem to connect to adb from recovery and mounting /data alone does nothing. After about 10 mins of using the phone, it becomes too hot(burns my hand) and it will shut down.
I've replaced 2 batteries so it's very unlikely that it's a battery issue. Also tried other chargers and wiping everything.
Phone OS: 4.1.2 stock LT5 before.
Did factory wipe/dalvik wipe + flash to CM11 4.4.4 and the problem is still present.
Betterbatterystats doesn't indicate a draining app, just high temperature.
Removing the external SD card and sim card had no impact.
I'm getting deep sleep when I turn off the screen, so it's not media scan being stuck. Mediascan disabled and problem still persists.
Pretty much out of ideas here, and hoping that you guys could help me out.
Any help is very much appreciated.

It's not just you. I experienced the same, as have others, for example see http://forum.xda-developers.com/galaxy-note/help/process-bug-kitkat-roms-t2834819.
If you really need Kitkat I suggest Omnirom as it didn't have the heat issues when I most recently tried it out again, about a week or two ago. The other Kitkat ROMs I tried all turned my GT-N7000 into a hand warmer/hot plate, as did some older ROMs. There are good reasons why GT-N7000 is no longer officially supported in CM - really serious bugs with very few people still willing to try to fix them. Otherwise stock Samsung + root works great with no killer bugs and huge battery life Anyone still remember when this device first appeared and it was famous for having longest battery life of any smart phone? Run stock Samsung, rooted or not, and disable all the stuff you don't use, enable the power saving mode and it still is one of the best. Not kewl tho.....:laugh:

Thanks for your response. I wasn't aware of this situation. But I was having this heating problem on Samsung stock firmware 4.1.2 too?
edit: just flashed to omnirom and it's still burning my hand.
In the team win recovery repairing internal storage gives me the error: unable to repair /emmc, so I just wiped it, problem is still there.

The heat comes when the CPU is working at max. This should be quite rare but can occasionally go on for a long time, for example if there is a lot of media content to be indexed. This would usually happen for just a few minutes after booting. Example: I use Archos video player and it indexes 1000s of movies on my home LAN via smb or upnp - this adds some overhead at startup but then settles to zero impact. It can also happen on connection changes as these are a trigger for lots of apps/services to activate/phone home/update profiles or content and so on. You could also experience heavy load on CPU if your 3G connection and/or wifi signals are poor and the device is constantly seeking better signal.
Some stuff you can do:
in stock Samsung enable power save mode - this limits the max CPU state to 1000MHz.
in a rooted custom ROM you can use any of several utilities to do the same.
This makes near enough no difference to normal use but will just throttle back the CPU when it is trying to max out.
You can disable notifications for open wifi networks.
In stock Samsung you can safely disable any of the apps that you don't use.
In rooted custom ROM you can do the same but you also have the ability to disable stuff which you need just to boot to a working environment so be careful.
Disable GPS when you don't need it. Disable bluetooth if you don't need it.
and so on....
If you use an external microSDHC card try it formatted as exfat instead of fat32/vfat. There is a horrible bug with spontaneous unmounting of the extra cards but it works better if they are formatted exfat.
On rooted stock Samsung my Note runs nice and cool and just warms up a bit if I spend hours playing games. It never gets hot like it did with custom ROMS. If I get into a mega brain dead bug eyed game session with sound high and screen on and very bright I get about 6 hours battery life. If I use it a bit more normally I get anything from 10 to 17 hours between battery changes, with screen time between 3 and 6 hours, and that includes using batteries that are a couple of years old. I never even got close to this kind of performance with custom ROMs. YMMV etc.

The heat comes when the CPU is working at max. This should be quite rare but can occasionally go on for a long time, for example if there is a lot of media content to be indexed. This would usually happen for just a few minutes after booting. Example: I use Archos video player and it indexes 1000s of movies on my home LAN via smb or upnp - this adds some overhead at startup but then settles to zero impact. It can also happen on connection changes as these are a trigger for lots of apps/services to activate/phone home/update profiles or content and so on. You could also experience heavy load on CPU if your 3G connection and/or wifi signals are poor and the device is constantly seeking better signal.
Some stuff you can do:
in stock Samsung enable power save mode - this limits the max CPU state to 1000MHz.
in a rooted custom ROM you can use any of several utilities to do the same.
This makes near enough no difference to normal use but will just throttle back the CPU when it is trying to max out.
You can disable notifications for open wifi networks.

Thanks for taking your time to write this. I've already disabled GPS/sync and turned on power saving. Clearing the storage now lets android calculate properly, and the Media/sdcard is gone from battery usage. But it's still running very hot and draining. CPUspy says 20% on 1400 and the rest on 800mhz when I'm using it. The system is freezing often and generally really slow.
EDIT: just used eMMC check and it says I'm brickbugged :'(
type VYL00M
Ran the test but it says passed.
Temperature seems to drop to a reasonable 35C when I'm in airplane mode.
With everything on and sync off it's not going above 40C even when watching videos or something, so I guess it's all good now.
So basically what I've done to fix it:
Wipe internal storage and repair all partitions
Flash to OmniROM
Turn off Sync/GPS
Problem seemed to be mainly on the internal storage corruption, maybe related to my bugged chip.

According to eMMC Brickbug Check my Note is exactly the same as yours - supposedly "Insane chip" but Memory check passed with no problems, and guess what? It works 100% perfectly running 4.1.2 rooted. I have the full capacity of storage available to me, apps do not freeze, everything works as good as new. It is absolutely stable and reliable and terribly boring (just how I like it). It never surprises me or does any weird stuff at boot or crashes or freezes. All the hardware features work, all the supported video and audio codecs and formats work, the networking is rock solid, I can rely on my VPN when away from home, GPS gets a fix in no time, battery life is excellent, video playback is great etc. etc..
I bought my 16GB GT-N7000 a few months ago, a used item on ebay. It is an unlocked retail UK item (boxed with all manuals, paperwork, accessories etc) so no network/vendor bloatware but it was supplied by the seller with Supernexus ROM installed and was obviously suffering from the usual problems often described by users of custom ROMs on exynos. After various frustrating episodes and trials of different ROMs I used ODIN 3.09 to flash an official Samsung ICS 4.04 firmware and 16GB pit file to restore the partition table and stock firmware. Then I ran Kies on Windows XP on the "virgin" restoration. It recognised the hardware and the firmware and notified me of the update to 4.1.2. I went ahead and updated over ethernet and also captured the official 4.1.2 firmware for purpose of backup.
Since then I have tried out various ROMs and have always been able to revert to stock Samsung 4.1.2 via ODIN and without going back to the scary brickbug "insane" ICS versions. As far as I can tell the brick bug is irrelevant if you aren't stuck on ICS. After trying numerous ROMs of various android versions I am in no doubt at all that if you spend half the time setting up a rooted stock Samsung firmware as most people spend setting up ROM X/Y/Z you actually get a much more reliable and useful device.
If you need a known-good pit file for a 16GB GT-N7000 you can use this: ftp://takla.linuxd.org/Q1_20110914_16GB.pit
I had a similar issue lately. Go to developer settings and activate the cpu load display. Processes and their cpu load along with a bar graph will appear on the screen. I found out that google's music app was hanging on my phone. This did not show up in BetterBatteryStats!!!
