4) and it's very very annoying... so much so that I sometimes (multiple times in a day, actually) wish to get back to Android 2.3.3, which I had before updating to Samsung's (India) version of Android 4.1.2 for my GS2.
What could be the problem? I rarely ever connect to WiFi (am always connected to GPRS/EDGE, but that has never been a problem in the last 2 years... the phone still used to get nearly a day of battery life) and the brightness is almost always at the lowest. I rarely use Bluetooth, GPS, etc. I don't even use Facebook and WhatsApp anymore, so the screen isn't used to the max. I've turned off all the Location Sharing settings for Google Maps and/or other apps (I use very few apps anyway, but have a bunch of them installed on the phone... none that execute in the background though | also not more than a couple new apps after my OS upgrade).
It's been nearly a week since upgrading the OS on my phone. Last night when I hit the bed at 1.15AM my time, the battery was at 100% (after charging). With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.
Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!
I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?
Or should I be doing something else?
Any help would be greatly appreciated.
P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this

Hi OP,
I haven't been on the i9100 for that long, but have also been annoyed with short battery life. As have many others from what I read. A 12% drop over about 8 hours of sleep, I'm sorry to say, doesn't seem that bad actually for an SGS2 with stock jb 4.1.2 and stock battery.
Personally, I tried different lightweight ROMs that are known to spare your battery. The advice to turn off 3g and other core functions never made sense to me, as I want an operable phone, not some sort of deflated piece of junk.
After reading on xda I went through Slimbean , Liquidsmooth, and other ROMs to see if they would increase battery life.
My current ROM is NeatROM 4.8, which actually seemed to give better results. Please note that this is purely subjective, though, I have no fancy battery analyses to back up my statement.
What REALLY helped was getting a replacement battery.
I tried Qcell 1950 mAh batteries. Stay away from those. They are clearly not 1950 mAh. Now running with a genuine Samsung 2000 mAh which is worth every dime.
Now I imagine you would be frustrated having to buy a new battery just because you updated your firmware and I do understand. I never owned the SGS2 before jb, so my choice was simple I guess. That having been said, though, the 2000 mAh battery really turned the phone into a whole new sort of usable. It easily lasts through the day even with regular use.
Just my 2 cents.

yea.. u said it...even i have tried several custom roms ( NeatRom, WanamLite,RR etc) all give 15-19 Hrs max.. and this also by tweaking all the settings..
S2 is a undoubted beast, but the cost in terms of battery is very hight..my previous Android Motorola Defy was a Mammoth in itself..huge custom fanbase and loads of ROMS + Awsome battery.
Any ways i got no regretts for having a S2..but battery s a lil concern..
Currently am on Asnet MIUI V5 and its going good..fast, responsive, smooth and decent battery of 18 hours avg..
@jsiv - i wanted to ask u a question.. which country u hail from ?? because the stock 2000 mah battery is not available in India, my region.

What exactly is battery calibration here? Please pardon my ignorance. I did a full charge when my phone hit got switched off the day after upgrading the OS. Is there something else I must be doing here?
I've had this problem right after the upgrade. So, I don't think it's an issue with my battery per se. It could just be JB.
How good is the Cynaogen Mod ROM in terms of battery life?
Or would it be wiser to switch to Android 4.0/ ICS?
I live in Denmark. I ordered it off Ebay, but I see now that the UK shop I got it from doesn't ship to India.
You searched Ebay for "Samsung genuine 2000 mAh battery" or similar?

This has to be done every time you do a ROM upgrade or change ROMs.
CM has excellent battery life when compared to other ROMs.
If you are switching over to ICS stay away from version 4.0.4 as it has EMMC brick bug.Any other version would be fine.

As reported before, it seems that many official JB ROMS are not as optimized as other national versions and are battery hungry. It was suggested to upgrade to the French release (XEF).

I did this... and unfortunately, it did nothing in my case.
I went to the CM site, but I didn't find any stable build for SGS2. Is there a thread on this site I can refer to for the same?
Also, what's the best way to go about installing a different ROM? I have so many apps, sms messages, pics, mp3 files, 3gp files, etc. Sure I can take a back-up onto my SD card. But won't I lose all the apps once I flash the current Android installation and install a new ROM? Any article or video on YouTube that addresses these points? Please point me in the right direction. I practically don't use my phone even half as much as before and I'm having to charge it twice a day, as against once a day earlier.
Also, the rapid battery loss seems to be causing the phone to heat up a lot if I'm on a call longer than 15 minutes or having the screen on for 2-3 minutes straight.

There is no stable version of CM 10 on I9100 because of the some issues. You can flash one of the nightly builds.They might not be necessarily unstable.
No you wont be losing everything when you install a new ROM.You lose once you do a data wipe.It is suggested you wipe everything before you install a new ROM.
With a data wipe you'll lose the following - SMS,contacts,call logs,apps installed and respective data.
What you wont lose - Anything stored in the sdcard partition - Pictures, Videos, Music, Apk files and Anything stored on the Ext SD card.(unless you format them specifically)
Best solution is to use titanium backup app(You need root). This way you can backup your apps and resp. data,wipe data-install ROM,and restore the previous backup on the new ROM.

Hi XDA
I literally don't know what to do with my Samsung Galaxy SIII for a bout half a year ago i updated my phone to Android 4.3 and things went a bit weird. First thing I noticed was that the phone was really slow to wake up from standby, sometimes I had to take out the battery because nothing happen. The second thing is that it sometimes get really hot even on standby. I can't make it though half a day without charging my phone! Today it got mad at my phone again and was searching around the web for a solution, I came by lot of forums with people who was dealing with the same problem, but no fix able. I found a guy who had a an app which could register the battery usage in a graph. After running the app i noticed the same as the guy from the video - my phone is pretty normal on use, but then I turn the phone on standby it goes insane (look at the picture linked below)..
I don't know how to deal with the problem. I have gone though the applist to see any remarkable apps, but nothing has cough my attention.
I hope you guy are willing to help me - Save my phone!

Wrong phone forum!!!
Here is your phone forum http://forum.xda-developers.com/galaxy-s3
Hi, did you solved your problem?
If not, i'd recommend System Panel app. Download it, install, launch. Then go to Menu->Settings, check Enable monitoring option. Then let your phone to be in idle mode several hours - maybe before going to bed. After it - go to SP->Menu->Monitoring->History (in bottom right corner)->Press chart in top left corner->Top apps. Then you'll see top applications that worked in idle mode.
For more information go to 4pda russian forum and search "Советы по улучшению энергосбережения устройств на Android OS" thread - google translate will helps

I think some app is malfunctioning , i would suggest using Greenify if u r rooted ,
And if u r on Stock ROM then i would suggest u to delete or disable the BLOATWARE.
It helped me hope this was helpful
4.3 on the S3 is extremely buggy especially without Samsung's patch ( which didn't do much ). There isn't much that you can do on stock Touchwiz, except maybe flash a custom kernel. I would suggest flashing a custom rom, but that is up to you. There are many choices for custom roms here including Touchwiz, if you like it.
I've been experiencing disappointing battery life since the android 4.3 update last month on my non-LTE t-mo galaxy s3. I know there's been a lot of discussion and advice by t-mo reps on various forums, but it simply isn't accurate. The party line is "something you installed on your phone is causing increased battery drain after the 4.3 update." However, my partner and I have two identical T-mo galaxy S3's. We have entirely different sets of apps installed on our phones. As soon as we installed the 4.3 update, both of our phones started to drain rapidly faster than before the update. On 4.2 our phones would last to 50% by the end of the day (~8pm) with light to moderate use. Now they're at ~20% by the end of the day, and I can see my battery levels drop faster just while using the phone. This is totally unacceptable. I've downloaded battery monitoring apps, and no apps I've installed are draining the battery, it's the system and kernel that take up most of the cpu. People are saying it's the touchwiz additions that are causing the system to use up more cpu cycles. I refuse to do a factory reset because there's so many reports of this not doing anything. There's clearly a bug in the 4.3 update for the SG3, unless it's touchwiz as everyone seems to indicate. How can I check to see if something is causing too many wakes?
4.3 works prefect here. same battery life as with 4.0 or 4.1.
it's not the fault of 4.3.

Hello everybody,
about two months ago, I had an issue with my installed ROM on my Redmi Note 2 Prime (I think it was this one: http://forum.xda-developers.com/redmi-note-2/orig-development/rom-cyanogenmod-12-1-t3288916 ). I decided to try out another ROM so I installled Bule's Mokee ROM ( http://forum.xda-developers.com/red...nt/rom-cm-12-1-mokee-bule-mokee-blue-t3328382 ). After a few days with this ROM I recognized a big battery drain while screen off so I installed BetterBatteryStats to get some more informations. It told me that about 50-75% of the time my CPU was running at 800mhz instead of deepsleep (at a normal day with about 1-2h of Screen-On-Time). It didn't look to me like something is creating a wakelock though (but maybe I am just unable to see this). I tried the next ROM: Daniel Pinto's CM12.1 (http://forum.xda-developers.com/redmi-note-2/development/rom-unofficial-t3310551) and again the same issue! I tried a full wipe of my internal storage, did not install xposed and did not install any titanium backup. The battery drain didn't go away. So i flashed another ROM: SlimMIUI V7.1.3.0 ( http://forum.xda-developers.com/redmi-note-2/development/rom-slimmiui-dev-stable-t3296594 ) and suddenly there was no more screen off battery drain! This went well for about three weeks and now I am facing the old problem again! Please tell me what I am doing wrong since I don't believe it's a ROM-related issue.
I installed these apps (according to MIUI):
9gag
AdAway
Android System WebView
Antutu 3DBench
Antutu Benchmark
AquaMail
BetterBatteryStats
BikeComputer
Burning Series
Chrome
DB Navigator
Dropbox
ES Datei Explorer
Google Play Store
Google Play-Dienste
Google-Tastatur
Greenify (wasn't installed before SlimMIUI)
GuitarTuna
Hacker's Keyboard
Hearthstone
irplus
Maps
Messenger
MX Player
mydealz
No-Frills CPU Control
Nova Launcher
Open Camera
PaderSprinter
QuickPic
scondoo
SleepTimer
Spotify
SuperSU
Telegram
TeslaUnread
Titanium Backup
Twitch
Unified Remote Control
Wakelock Detector Free
WhatsApp
Youtube
What I have tried so far:
- changing ROM (clean flash)
- not installing xposed
- not using old backups
- changing the battery
- using airplane mode
Also, I wonder why there are these gaps in the battery history since I didn't reboot yesterday...but these gaps don't appear every day.
Please help me to fix this really annoying problem and make my RN2 great again!
Thanks,
Kooneybert
The biggest drain comes from all the Xiaomi bloat. Read this thread for details on how to reduce the bloat. In my experience, the second main culprit is WhatsApp. I've had to stop it from giving sound notifications (or even vibrating) when messages come in. Now, I have between 90%-95% deep sleep on idle. Basically, anything that turns on audio could be a problem, because sometimes audio doesn't go off afterwards.
You might want to try GSAM Battery Monitor for more information about what is eating up your battery.

Thx for your reply! The problem is not MIUI-exclusive. CM 12.1 from Daniel Pinto is pretty slim but gave the same result (from the first day on).
Whatsapp can't be the only problem since all my friends use it and nobody have this problem (some of them also even have a RN2). Also, my phone is in silent mode almost all the time so no app is allowed to make noise or vibrate.
I just installed GSAM Battery Monitor but I don't know how to use the app/read the provided data. I could use some help there, too.

You can only be sure if you have a really skinny ROM whereby all the unnecessary Xiaomi stuff has been removed. There are all sorts of things going on in the background - including things embedded in the boot image.
There are also possibly optimisation issues with the kernel. All the ROMs seem to depend on the same binary kernels, since there is no GPL release of the kernel source code. You might want to try one of the skinny boot images by @jajk
As for GSAM, the best to learn is by trial and error (tip: tap on everything visible to see where it leads to, and what information it gives you).

...on all three ROMs? Only for me? With this effect? On some days, it reduces my battery by 50-80%! Hard to believe it is not a bug. Also, SlimMIUI has reduced Xiaomi-Stuff, Daniel Pinto's CM 12.1 looked even more clean to me.

Aren't there different kernels out there for the RN2? Bule's Mokee-ROM uses a modified kernel e.g. Does every ROM come with a certain kernel or may it be applied from the ROM before? So maybe I am still using the kernel from Bule's Rom with my MIUI?

This will help me to read the information but it won't help to understand them, too. What do you think about this:
Kernels: You can't compile a custom kernel without the Xiaomi kernel source code. All you are left with is tinkering with ramdisk in the boot image

...is this normal? The Kernel is the biggest battery sucker on my tablet aswell (which still has great battery). What do you think about the 8,5h of wakelock time produced by the kernel? If this is the problem, what can I do to solve it?

A "screen awake" of approximately 50% seems to me to be highly excessive (at least, if the phone was mostly idle). In nearly 12 hours, I have a screen awake of 55 minutes - so 8 hours in 15 hours seems strange. How exactly were you using your phone during this 15 hour period?
Perhaps the custom boot images by @jajk might help (see the first link in http://forum.xda-developers.com/redmi-note-2/general/roll-skinny-miui-t3309873). I am currently on v714-15 of the custom boot image.
Sounds like you may be having issues similar to what I was dealing with not too long ago, but my 'solution' was to install Bule's Mokee (still don't know why this ROM worked where so many others failed). Daniel's CM 12.1 and Xiaomi.eu were both giving me significant drain with and without the screen on to the point where I was sometimes finishing the day with an hour and a half of screen on time and ~20% battery. Now I'm getting up to double that.
One thing I can recommend is using MiFlash/Fastboot to do a total reset from scratch. Didn't really work for me, but you may be different.
Other than that, although it's tedious, you may have to install 1-3 apps per day after a fresh install to see if your battery holds at first and then dies sometime after installing certain culprits. It takes forever, but at least this helped me when I moved to Mokee to make sure that it wasn't any of my 'vital' apps that were causing me issues.
Best of luck!
Funny thing that the Mokee-Rom did SOLVE your problem. In my eyes this Rom was the beginning of my problems.

What is the difference to using TWRP?
I will try the Mokee-Rom tomorrow. Since I never used MiFlash/Fastboot before I won't use it until you tell me that there is a difference compared to doing a full wipe with TWRP.
I tried flashing the Mokee-Rom again but the problems go on. I installed very few apps and the battery is still very bad. Today I had 18 minutes of SOT and though I lost 14% in a few hours. This time it was caused by Whatsapp:
It always seems that some apps just don't like to stop doing something but it's random which app is the problem.
I am totally running out of ideas so please help me guys!
I'm on Mokee and satisfied with battery, this rom have less problems than other (for me). First of all i have installed MobileRadioActiveFix with xposed, then SmartNetwork to turn off wifi while my screen is off. I've got few other things but right now i've got over 4h SOT so it is not bad score.
i have the same problem! it happens with flashing severals ROMs (mokee by bule?) and starts battery drain with all ROM, it never goes... is not the battery, the cable or the rom..... i dont know im disperate... the sot changed from 4-4.5 h to 2-2.5 h... with all ROM, please help us and sorry for my bad english
Well i had situation that my SOT suddenly got down but i was still on march rom. After update to latest version without wipe it is ok right now.
Have you tried with wiping all with internal memory? Maybe something is there still and that is making a problem.
Another thing that came to my mind: have you changed build.prop and have copy of it? If so, delete it. I had some problems becuase of that.

every rom i have flashed was a clean install (full wipe of internal) after latest miui update, when the phone shut down at 0%, i put off the battery for 10 min, after i put back and the phone was at 19%!! now is on charge... maybe the problem is solved.. i will post if it is solved (sorry for my bad english)
I had that problem with earlier phone and it drived me crazy. I was not able to find what was the cause unfortunatelly. Phone was given to service point to install branded rom (it was not available for public). Right now i do not have problems like that, if i have some i'm able to find solution somehow. Although what i wrote helped me when i saw SOT problem.

You can try:
-discharging until the phone shuts off
-charge it in OFF mode until its full
-disconnect charger, put battery out and in again
-connect charger, charge it to 100% again...
repeat until it shows 100% when connecting the charger.
For some ppl this seems to work.
Please let me know if you find out something!
There are lots of ppl out there with exact the same issue!

EDIT: Installed PSYROM V3 for testing purpose right now. Lets see how it does with skynet and a freshly calibrated Battery with the internal calibration tool of the rom. I`ll give feedback on monday.
Update to my issue:
-I did a full wipe (including internal memory)
-Installed PSY ROM V3.0 and Skynet
-Wiped cache/dalvic
-Startet the phone, installed my apps etc
-Charged it to 100%, waited 20 more minutes
-Did the Battery calibration with the internal calibration tool (everything is described in psy mans thread)
-Did a reboot
So far there is no Battery Drain, after the (long) reboot, wich took around 5-10min because miui is optimizing apps etc the phone came up with 97% and stayed there for almost an hour now.
I´ll give you guys feedback next week. Hopefully we get this sorted out.
You can try Angels & demons ROM v8.0 it is providing me with great battery life, so much better than stock or stable version of MIUI. I use Gsam battery monitor, and I have not faced that issue so far.
I'm getting very poor battery life with my Note 4, which seems to be much worse since a recent update. When I first got the phone a few months ago the battery life was fantastic but now it's almost as bad as my old Moto G2!
I get up in the morning and over a couple of hours spend a bit of time (not constantly for 2 hours) on WiFi checking e-mail, social media, etc. and my battery goes from 100% to 70%. Then I don't use the phone, go out for about an hour listening to Spotify music (offline) using my BT earbuds and when I get home it's down to 40%.
As you can see from the screenshots, it doesn't seem to be the apps I'm using that are draining the battery as "Android system" is responsible for 74% of the battery use. This has maybe 50 packages listed under it, so I think it will be rather hard to identify which one is responsible.
Any ideas what I can do to fix this?
Are you using MTK or SD?

Dont use MIUI, that's a good start. (hopefully you have Snapdragon variant otherwise you're screwed)

I can't remember how to check but I'm 99% sure it's SD. It's mido if that proves anything.
I installed Greenify and hibernated a few things and that's helped a bit, although it's still not brilliant. I also installed Amplify but the results don't mean anything to me, so I've attached some screenshots in case anything stands out (more in next post due to max.4)
Remaining screenshots.

Yeah I've been thinking of changing ROM tbh. Something that annoys me about MIUI is it only allows you to enter a numeric decryption code on boot. I know how to set it to something different than the unlock code and normally use an alpha-numeric code but that's not an option with MIUI as I wouldn't be able to enter it!
I have App Quarantine installed so I was thinking I could try freezing certain system/MIUI apps but if I'm going to change ROM I guess it's not really worth it. The problem I have is choosing a ROM, as there's so many and battery life, whilst important, isn't the only thing that matters to me. The decryption code thing is important, as is full dual-SIM functionality. OTA upgrades is one thing that MIUI has in it's favour and I guess that's not an option with third-party ROMS but upgrades being made available in a way that they can be installed without wiping the phone would be nice, if possible. Dual apps, Second space and Call/SMS blocklist are all quite handy features in MIUI too.

MiracleDROID, give it a go, it's one of the better ROM's i have used on Mido very underrated.
Or OmniROM if you want weekly OTA (Delta updates) just like in MIUI.
And dont expect miracles right after flashing it, give it atleast 1 charging cycle to settle.
Same problem with me .. Battery temperature goes to 41 degree ++ and after night I have to see my low battery
Hi there,
I purcharsed a Pocophone F1 two months ago and, after unlocking bootloader, I ran into serious battery issues with the phone only not lasting a day when in the same usage it used to last about three days before. So I came back to the shop and they exchanged me with another one after two months (because they first attempted to understand the issue but finally lost the phone).
So, when I got this new phone, like for the previous one, I found the battery life amazing. Then I unlocked the bootloader and flashed Magisk, and it suddenly dropped : I was losing about 1% of battery every 2 minutes.
So I re-flashed the stock ROM, without Magisk or anything, but the problem didn't disappear. I finally wiped everything, flashed the stock ROM, relocked bootloader (which wiped a second time the data), but the problem was still here.
Currently, I'm running the Havoc 2 ROM (Android Pie) flashed with Open Gapps and Magisk, usingSphinx Kernel. It worked great at the beginning of the day, but for no apparent reason my problem appeared again a few hours ago. I attached a few screenshots to illustrate it :
The first one is when going into a terminal and typing `su` then `top` while I was listening to music on Google Play Music (there was no other application opened, no WiFi, no Bluetooth, no GPS, brightness at, let's say, 50%). As you can see I was even in power save mode. I also tried to use other CPU governors like `blu_schedutil`or `powersave` but that didn't change anything (the default and current one is `schedutil` for both big and LITTLE cores).
NOTE: Don't mind about the usage percent and time, I used the "reset" button to check what was going on.
The second one is the result of Kernel Adiutor in the same context, and the last screenshot is when I have only this application opened (no terminal, no Google Play Music). Because of this, the Pocophone heats up, of course.
Also note this problem can happen randomly ; for instance I just re-launched Google Play Music and played some tracks, the big cores remained at near to zero usage percent (while the 8th core was still as its maximum).
To sum up what I tried:
* Changing ROM doesn't help ;
* Using a custom kernel doesn't help ;
* Re-locking the bootloader doesn't help ;
* Wiping everything in TWRP (internal storage, vendor, data, etc.) doesn't help ;
* Going in power save mode doesn't help ;
* Setting the CPU governor on "powersave" or other doesn't help ;
* Closing all other apps doesn't help
Does anyone have an idea of what's going on? The same problem happened with two different phones, which is very strange ; I don't have any background application running (I manually stopped them all, and the problem was here even after flashing the stock ROM alone, with no non-stock application installed).
Thanks in advance for your help
Try going back to full stock stable with stock recovery via fastboot method. Drain battery to 0 and full charge.
Are you having good cell reception all the time?
I already tried this and this changed nothing. And yes, I had good cell reception all the time.
Because of some posts I finally found when looking for my apps, I found Google Play Music was eating battery on some random devices (sometimes it can drain battery at an amazing rate on several different devices, but no one knows why). The battery life seems better know. Still, this doesn't explain why I was experiencing the same problem with the stock ROM with stock recovery, without this application or any other.
The phone is brand new? If not, have you checked the health status of the battery?
I got mine second hand from aguy at work and it seemed OK on stock MIUI, but I noticed much faster drain on Lineage OS although everybody saying is one of the best for battery life, finally has seemed to get better.
I am using Havoc with pico GApps, D8G kernel (no oc) and FDE.AI(paid). My idle times are much better, and overall use too, the performance in games is much better too, but I've opted for some over clocking to boost gaming so the drain on heavier loads is greater as expected.
