hi guys,
so after much hesitation, i upgraded my phone to the latest stock at&t 4.1.2...here is what my config was prior to the upgrade:
Android Version
4.0.3
Baseband Version
I7777UCLE5
Kernel version
3.1.0-rc8-Siyah-v4.3.3-nomswap
[email protected]))
Build Number
IML74K.CLE5
I used to get decent battery life with the above setup...but after the upgrade, betterbatterystats is reporting 7%+ battery loss per hour...in order to narrow in on whats causing this massive drain, i have disabled all of the custom downloaded applications using titanium backup. Despite this, nothing has changed...
before i start to head over to the custom rom/kernel, i wanted to seek out to see if anyone else who upgraded to 4.1.2 is having same issue? and/or if there are any other suggestions on the battery drain?
Thanks for any constructive feedback...

7% per hour is excessive, even on stock kernel.
Read through this thread in the General section to get an idea how to identify and solve battery drain issues. You may need to root the phone first, if you haven't.
Also, if rooted, you can use the application Greenify to help determine and also hibernate applications that drain battery life.

yeah i also thought that 7% was very excessive....i am already rooted, and doing all that i can do identify what is draining the battery...i did see that you had mentioned Greenify in some other thread, shortly after i posted this...since then i have installed that application, and trying to figure out how to use it...
thanks again
Edit: sorry wanted to restate that i have disabled all of the custom downloaded applications...
Greenify is a great app!
If you just recently upgraded to 4.1.2 then you likely updated your Google play services. Google search it. It has been draining battery like crazy on lots of phones.
Try turning off location services or hibernating maps or Google now.

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.

Hey guys. Just saw this article stating that the G3 has less battery life with lollipop: http://www.techtimes.com/articles/3...alaxy-s5-htc-one-m8-nexus-5-lg-g3-results.htm
Are you guys running LP seeing a drop in battery like the article??
Im not on stock but I am on Lollipop and the battery life for me has been about the same. I feel like Google really dropped the ball with Lollipop as far as battery life is concerned... like they were talking up project volta and how it was supposed to make battery life 36% better on lollipop for certain devices. Yet most devices seem to be struggling to keep the battery life they had before the lollipop update. I know there is a lot of factors and development isn't necessarily going to be perfect with such a new release but still...
I get at least the same if not better battery use, for me typically 80+ hours before charging, my record, 124 hours.

One thing everyone must remember. Not all apps have been upgraded to utilize any new programming APIs, etc based on Lollipop. Lollipop under the hood is a different environment. No longer is Dalvik around. It's now ART. Some apps still do things that are only available under Dalvik, hence they do not work under LP.
Also, APIs go out of date, also known as deprecated, as OS'es mature. Apps that continue to use old, out-dated API calls, or were improperly programmed from the beginning but could get away with it in older versions of the Android OS, are now showing their issues. This can result in either the app not working at all, or the app could drain the battery.
Android apps are a different beast from your normal PC Windows application/program. They should not run in the background if minimized/when a user switches out. They usually go into a suspended mode so that they are not consuming resources. Out of the box, when an app is written, all of that handling is set up automatically. However, it can be circumvented due to someone not understanding the Android app life-cycle, or they know it and don't care, and just do poor programming. Either way can result in an app that misbehaves and drains the battery, as well as consuming resources (memory, CPU, etc). That also leads to battery drain.
So, I think part of this is Google, but I also believe that most of it is due to apps that are not optimized for Lollipop. I would like to see, or know, if these tests were run on straight stock with NO user downloaded apps. That would give us a clearer picture as to whether or not LP truly does gain better battery life for certain devices (I read that as newer devices).
No battery life difference for me.
Only difference I've noticed would be the stock LP gives better battery life than AOSP

Yeah I keep forgetting about the out of date API's but I practically use only Google Apps, I pretty much have everything I need on Google's platform. I only have a handful of apps that aren't google but I rarely use them. Still haven't noticed a change in battery. Not that the battery is bad per say my battery is actually pretty good especially compared to my S3 back in the day. Ive just been seeing other people complain in different forums. But you're right they are probably not using fully optimized apps for lollipop if they are having battery issues.

My wife and I aren't that popular, so we don't talk on the phone much. She does use hers a LOT for games. When we got our G3s, I picked up a Verizon LG G Tab 8.3 VK810.4G as well, so now I spare my phone battery a lot for music in the car, GPS, some gaming and quite a bit of TapaTalk or other web browsing. About the only time I do any of those on my phone is when I'm at work killing time sitting on the toilet, or waiting for my lunch to heat up in the microwave.
gosh one of the main reason i was going to upgrade to LP and reading this it doesn't seem worthwhile anymore. are there any reasons to upgrade to LP other than maybe material design? it seems sort to just be a ui makeover now...

ART instead of Dalvik. It's much smoother now.

Another thing to do is give it a few days after upgrading. At first, you might see poorer battery life but give it a few days and it might stabilize after that and you might see better battery life.
Also, once you've done this, start monitoring the battery section to see which apps are consuming the most battery life. This should give you an idea as to what is going on. That can help you pin point better misbehaving apps.
Also, I use the Snap Dragon Battery Guru app. That can also help pinpoint apps that might not be behaving correctly, plus it can do some managing of things to help preserve battery life. Not sure how much it helps, but it hasn't hurt, so I continue to use it.
Just some helpful hints that I've observed with this phone. I used to use Greenify, but I have found that I can get just about the same battery life without it as I did with it (at least on this phone), so I've since removed it. But, it's still an option to look at it, and it doesn't require root any more, which is nice for those that don't wish to root. And it has helped me in the past with other phones. I just haven't found that it helps that much with this phone.

Note that stock LG Lollipop builds 23A & 23B result in the SnapDragon Battery Guru app claiming it's incompatible when you go to it's Play Store page, although I haven't tried sideloading/restoring it from Titanium Backup.

Ahh. Since I haven't upgrade to LP (still on stock and happy as a clam), this is good to know.
Battery life does not change whatsoever. The display is always the culprit. Can get 5hrs of screen time sometimes 6 per stock battery.

Which is why I believe, as I stated earlier, this points to misbehaving apps that are not "tuned" correctly for LP. It's always better to just wipe clean (FDR) and then start restoring apps one by one to see what might be causing it. But also, give it a few days to settle down too.
I'm still waiting for the "official" release and then, will wait to see if either root can carry forward or else, the latest root still works on the official release.
T-Mobile users can now upgrade via the software tool on their Windows machines (not available as an OTA yet for them). Seeing how the G2 is getting it already, I have to imagine the G3 is not far behind. I'd much rather they just give us 5.1 to fix the memory leak.
I have noticed much better battery life on 23B Lollipop. I'm not rooted or anything, but for example I can listen to Audible for my daily drive into work that takes me 1.5 hours and the battery will only drop to 99%. I got 23B following another thread here, but my wife got a replacement G3 and it offered the update to 23b before the SIM card or SD card had been put in the phone. My son has a G2 that got the official Lollipop and it actually required two updates to get there. 1 just installed some system prereqs.
I'm in stock 23c and battery life is the same as it was under kk which for me is a good thing as I got excellent battery life under 12b. I'm not rooted because I want to wait and see if/when another ota comes out to fix the Wi-Fi sync issue.
I just finally updated to 23c. Seems wifi works fine for me thus far. I'll see how battery life is tomorrow after a full charge /discharge. Everything seems pretty snappy so far. I didn't even do a factory reset. Hopefully I won't have too.
Hello everyone,
My s6 Edge does not go to sleep. It drains huge amount of battery while idle.
I need urgent help. I have disabled all AT&T bloatware. But it still does not work.
I have also tried hard resetting it, it does not work. Battery continues to drain.
Thank You.
Is this something new or has it always been like this? Btw, which version of LP are you on? 5.0.2 or 5.1.1?
Its new, LP v. 5.0.2

5.0.2 seems to be notorious for battery drains...check if your device has the 5.1.1 update which seems to be better in terms of RAM management. Also, are you data or wifi...if on data, then LP is again notorious for a world famous "mobile radio active" bug...it's all over the web...So, the best solution would be to either put the phone in deep freezer until Google fixes the huge bugs in LP or sell your phone...just kidding...
After updating your device (if there's any), do a factory reset...it should solve your problems...hopefully
Does not go to sleep? Check your settings about screen timeout..The battery drain can be fixes through system update..if samsung has any update ready

I hard reseted my phone, disable all bloatwares, haven't installed any apps, haven't signed in to anything (even google, only signed into samsung account). charged to 100%. Left the phone for 4-5 hrs, battery drained to 81%.
fliptroniks said:
I was going to say just make sure you dont have too many apps running and you can also download a battery saving app on the play store for free which can help. It sounds like theres something you have running draining your battery though. Keep in mind however that the galaxy s6 edge when charged to 100 percent can hold a charge for quite awhile, but if your only charging it too around 40 or 50 percent it will die rather quickly.

What does it tell you in the battery stats? That's the first place to look. Is Screen at the top or something else like Google Services or a fitness tracking app? Send a screenshot of that as a starter for 10.

Your best bet is to install TWRP, root, and flash "No deep sleep fix", thats if you dont care about tripping knox of course.
Seems like an aggressive suggestion since we don't know the root cause yet. It might not be a wake lock issue; it could be location tracking or updates getting stuck. I'd rather see the battery stats first.
Screen is not even on the list, i haven't used my device for more than 15-20 mins (used chrome & inbox for 15-20 mins in the morning)

Google Services like I thought. There's a number of things that can cause this as it's quite a fundamental service. The most simple fixes are:
- Make sure there's no pending updates in the Play store. These can work havoc with the battery when waiting for manual approval
- If this doesn't work, remove your google account, reboot and re-add it. For some reason this can fix the sync issues that cause drain
- Still no dice? The next one is to backup, factory format then restore your backup. It's a bit extreme but sometimes when you update your software it causes a glitch that only goes away with a factory format
Each time you try a fix, let the battery fully charge then check the stats a couple of hours later.
Thanks for the suggestion, I will let u know the results soon.

Tried the third step many times before, didn't work.
So, yesterday I tried the 1st & 2nd step, worked like a charm, I was happy but today, the same results (battery was draning like i was playing games). So I completely removed my google account and left my phone for a few hours. Here is the result (see attached). As you can see no Stupid Google Play Services in the list but what is eating my battery ????

Again, LP has a world famous bug called the "Mobile Radio Active" bug. What this means that if an app uses the data services for some odd reason LP keeps the mobile radio open even if the app does not need it any more...So, for all you know ur issue is Android related and not your device specific. Oh btw, the upcoming M also has this confounded bug...so I believe we will be plagued by this bug for the foreseeable future...And I dumped my iPhone for this buggy Android...Dang!
How is your reception, If most of the time your phone struggle to get reception, it may be part of the problem, just my 2 cents, not an expert, but myself trying to get rid of the google service battery bug...
Better battery stats would give detailed information as to the cause, yet it requires root on all lollipop devices. Helped me find the exact cause of my phone never sleeping
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.

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

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.
problem persists... is there a method/app to calibrate battery that works?

Not that I know of. I`m facing the same issues like you here.
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.
