Serious battery drain with minimum usage

Hi all,
The battery life of my 4month old SGS is becoming shorter every week! I can 'almost' last a work day (8 hours) with a fully charged battery and minimal use.
I had this problem also on the stock firmware, Darky's rom 8.x was a slight improvement (much faster tho!), Light-ning rom and Darky's rom 9.x.
Everyday I charge my battery untill it is full, when my alarm goes off it's already at 98% (it's still hooked up). When I'm in the train to school, my battery already dropped around 86% (being idle). I check some mobile websites, my e-mail and read some twitter messages.
Because I know services as Twitter (I'm using Tweetdeck) uses alot of resources and battery, so when I'm done looking I always shut down those programs. And I often do an 'end all' task in the 'System' app which I purchased from the market lately to monitor my battery.
During the day the only thing I do is check my mail and some websites, but not for long, mostly it would be around 5minutes or so. So WiFi is turned OFF, GPS is turned OFF, and only GMail synchronizes with default settings. So what's the deal? Is my battery slowly dieing because of oldness, or is there another problem?
Thanks in advance for helping me! You're doing a great job!
Sincerely yours,
S1GNZ

after flashing your custom roms of choice... did you ever do a battery calibration?
like let your phone drain till it dies on its own... turn it on againa nd let it die again to completely drain it to the point where u cant even turn it on.
Then plug your phone in to charge and let it charge to 100%. Keeping the phone plugged in turn on your phone into recovery. Then clear battery status.
Then reboot your phone into normal mode and let it continue charging till it says 100%. WHen you unplug your phone it SHOULD say 100% still.
This normally fix the problem but if you notice that your phone is dying quickly still then PM me.

One small advice,try logging out google talk,of-course if you are not on it much,it will give you at least 2-3 hrs more.
Also,there is already a thread active on this forum 'dont kill your phone
,give it a life' give that a read.
Mainly this battery drains are there because of apps doing sync. or polling.identify them and adjust settings.

I've been browsing these forums lately, and I've also come across a thread which advice is just the opposite and that you should NOT do this, any advice if that's true? And is it also true that deleting the batterystats helps?

Am I auto-logged in on Google talk? If so, how do I log myself out :$? So Google sync might drain it? (Mail, Agenda, Contacts?)
Thanks for the quick replies! I really appreciate it!
Sincerely yours,

I am not 100% sure if you auto logged or not.I believe not but if not so , then open app,press menu/setting button on phone,select logout.also if you not intending to use data network,press power key till you see a menu turn off,data network,turn it on when you need it.These small things saves some power.
If you dont want to mess around with this little twiks then 'juice plotter' is the app for you.it will manage lots of things and defi. saves battery.
BTW based on your usage desc., I think I use it in similar way ...almost and yet phone makes ~2 days.

You of course wouldn't be doing this alot nor should you NEED to do this often. It's only something you do when you're experiencing what you currently are.
Personally I have no idea why anyone say u "Should NOT" do this.. it's not like you're altering anything hardware wise. It's mainly software and power usage aspects.
Like I said to each their own. Some people say custom roms are a "No-No" cuz it messes with the phone in more bads than good and some says stock roms are for noobs. You dont HAVE to try what I said, it's merely a suggestion of fix or methods that seems to solve the problems others have encountered.
Clearing the battery status pretty much resets it's counter to 100% and from there it will "calculate" the life of the battery from full to empty. It's a calibration thing.
Now on regards to usage, keep your data plan off and auto-sync off when you're not using it. Leave your wifi off and gps off as well.. pretty much keep anything you dont need off until you need it. Some samsung apps does a background run thing where it'll auto turn on and auto run in the background which drains ur battery quite badly. If you don't use goggle talk or samsung chat apps, there are many ways to remove them completely so it won't mess with your battery life

Simple you installed a rom with multiple posts on battery drain problem .
A rom that also tells you about battery drain problems /fix on its front page .

Okay! And you're right, it logs me on when I start the app. But I logged me out, just to be sure. I know about turning of the mobile data traffic, I'll see how much it saves. I think I came across juice plotter, but I'll look into it. Thanks!

Don't be offended by what I said! . I only wanted to make sure I'm doing the right thing, I appreciate your criticism though. I did what you said and fully drained my battery yesterday, kept it charging overnight, cleared the batterystats through recovery mode and at the moment it's charging till 100%. I will see if it helps!
And according to my usage, I have Wifi and GPS turned of as default. And because I reinstalled a new ROM inclusive data wipe I don't have much chat apps installed, maybe there are some default apps that don't show up in the 'System panel' app though?

Care to explain a bit further?
FYI, I installed these ROMS:
past: Stock firmware 2.2.1
past: Darky's ROM v8.0 Gingerbread edition
past: Light-ning ROM 2.2 (if I'm correct, it's probably the latest)
current: Darky's ROM v9.2 Extreme edition (9.2 should've fixed the battery drain, am I right?)
Can't thank you enough for the replies!
Sincerely yours,
S1GNZ

im having similar problems too. calibrating doesnt really make a difference.
i installed an app called task identifier which is brilliant it tell me whats happening when the phone is asleep. the only trouble is i dont understand what these processes are so i cant disable them.... is there any sort of app out there that completely logs / signs you out of every app ??
i have 108 apps (not including system apps) and its hard trying to eliminate the battery drainers

Care to explain a bit further?
As it says post lots of with battery problems big big percentage running Darky rom .
current: Darky's ROM v9.2 Extreme edition (9.2 should've fixed the battery drain, am I right?) You would have to ask on dARKY Post .
Look at Battery drain thread LAST POST OR SO MAY BE OF INTEREST .
I am of the opinion that if a rom breaks something then installing more roms will often not fix the problem . I prefer a blank completely wiped phone in such cases with no trace of any rom left on it .
jje

@azzledazzle 108 apps? really ????
I don't have that much on my PC!
I think we should start narrowing down which apps drain most juice. I've been using Advanced Task Killer just to narrow down a couple.
example:
Sound Hound - starts on its own
Facebook had an issue with notifications push, when disabled, it still sent notifications to my phone. But I think they fixed it in the latest version.
We could start adding versions to know which app is a 'juice drainer'

[Q] Battery Drain issues , need help !!!

location service off for google apps, gps off (only wifi network location enabled), 3g data most of the time . and why such wakelocks ?

If you can't find the source of the drain try a factory reset.

We went through so many threads like that, my man.
Do a search.
For the headup, assuming that you have already turned off Android location access, turned off Google location access, turned off auto-sync (I know you said you needed it but just for now, off it), turned off gps/mobile networks, do the following
a. disable Knock On/Off feature
b. disable CIQ (if you don't have CIQ, then ignore this step)
Note: do one by one and make an observation how the battery life behaves after each change.
Oh, btw, reboot the phone, say, right after unplugging the charge.

yup done all of that ! still same result ! even turned off fast dormancy as my network provider doesnt support it ! im not a noob to simply open up a thread in the q and a section. i might be new to this phone, im not new to android. anyways is your android OS staying awake ?

In term of battery life, I was considering myself as one of the unlucky one but after done all those, I got pretty good result. Normally last about 3 days with 6 hrs screen-on time and 4 hrs talk time. No wakelocks

you should know better than to give stats.... standby hours and battery life is varied alot by user, ambient temperature and etc.
OP if you feel thats not right, flash another rom see if it help, I'm using energy rom, its good for me so far.

Try remove some bloat and apk with titanium... A regular user can often remove 100 apk from these roms! And use bootmanager and greenify! Greenify is must have!

Don't hope, fix now.
If I was you, I would backup all my important personal info on the phone and factory reset it.
I would do those tricks one by one w/o installing any app yet and see how the battery fares after each charge.
General speaking, we need to understand the root cause and find the solution from there, if it needs to be rooted to fix the problem then you root it otherwise, blindly rooting and assuming everything else will fix isn't the right way to debug.

[Guide] Battery & Performance Tips

Just thought I’d put a short guide together on what I think are some things to do to get the most out of your spanking new Samsung S6 when you get it or you already have it. Most of you guys might already know most of this or might not. Just thought it might help some people. This ain’t rocket science but every little bit helps!
Battery:
This is the hardest thing to do because like a fingerprint everyone has a different set up with apps and how they use their phone (wifi vs 3g vs 4g etc) that screen on time will always vary. Also you don’t want to turn everything off and cripple your brand new smartphone just for your battery. There’s a balance.
However here are some general things to do that do help:
1. Install Greenify from the Playstore. I have found this is the number one way to stop drainage. This app will hibernate apps when not in use. It doesn’t stop their functionality at all but hibernates them.
2. Don’t use Google Now. I think it’s a gimmick and does bugger all for me however if you use it it will drain your battery big time. Of course if you love it then use it!
3. Don’t use location services. Another big drainer. Just use it when you need it. However if you have apps that need it then of course leave it on!
4. Use ‘auto’ on screen brightness.
4. Don't use the Facebook app. It's a massive drain of battery. And Facebook is awful.
5. If you continue to get big drainage then download Gsam battery from the Playstore and look at the ‘wakelocks’ – this way you will be able to see what’s draining your battery. As a general rule your phone should go into deep sleep for at least 80% of the time.
This way you should get 5+ plus hours of Screen on Time.
Performance:
Here are a few things only that really do help with speed and performance - even though this phone really doesn't need it it still helps!:
1. Go to Dev Options and change the transition animation scale, the animator duration scale and the window animation scale to 0.5. This little thing speeds up your phone like nothing else.
2. Root* your phone with Cf auto root. And then start debloating. Get rid of whatever you want by downloading Titanium Backup and going into each app and freezing whatever you want. Freezing is safer than uninstalling but does the same thing. Debloating is a must!
*And yes I know the Knox arguments for not rooting but I've rooted every Samsung phone I've ever owned and sold every Samsung phone I've ever owned.
*And yes I know that you won't be able to use Samsung Pay but it ain't coming out for months and there's too much freedom you get from rooting to not do it because of this.

Just an FYI... Google Now does not drain your battery!!

do you have any battery life screenshots of your s6 with these steps done?

This is not untrue advice but it is also not new to this device at all. This is the same advice on android years ago and it's basically saying turn off everything that drains the battery then you get 5 hours of screen on time. Well most people want to use google now, facebook, and location services so that defeats the purpose of the phone. Really there needs to be some serious improvements in battery tech but so far we as consumers are allowing companies to get away with putting sub par battery performance in their flagship phones and we keep buying them anyway. I am guilty of it too but it does not give companies any real incentive to focus on battery life.

Of course if you turn location off but that's the point - it's made to be used with location on which will drain battery.

Parking reminders?? I don't need that as I live in upstate NY (Dutchess County)... pretty hard to forget where you park your car lol.

@poczynek
I have a GS4, and I'm looking to get a GS6 soon.
I have read your post and I am not sure if what you claim will bring any evident increase in battery life at all.
1. Greenify - What does it do? Why should I greenify an app? What apps/services did you greenify to give you an increase in battery life?
I can't say for sure but if I ran my GS4 without disabling apps vs disabled apps I bet the battery life/screen on time would be similar.
However I did disable a whole bunch of Samsung and other bloatware apps that came on my phone because I don't want their bugs or services to be running unnecessarily.
I have a looked at Greenify to some detail and thought to myself why bother? All of the services and apps that are running are fine...why would I need another app "Greenify" to manage something that is native in Android which is to simply disable bloatware apps.
Please provide a real example of what you would Greenify, as opposed to simply disable and what/how it benefits you?
I think I have over 70 apps disabled on my GS4 because they are things that I don't use.
2. Google Now - well this depends on if you use Google Now Everywhere, with it's ability to talk to the phone by saying "OK Google". In addition, Google Now has that card system which will send you news and other related cards based on what "you" the user configures. I'm not sure if you do setup all of these cards results in a great amount of battery drain either. I personally don't use Google Now voice activation or the cards, but I have not disabled the app.
I can agree with you that Google Now's voice system will drain the battery, but that's expected because it is always listening (if you enable that).
3. Location Services - by this you mean the GPS/Cell/WiFi location capabilities? I can tell you that I leave my GPS on GPS Only mode. I don't want my phone to use cell towers or WiFi to help improve upon the location of me. I have had no issues with doing this. I do believe if I use cell towers and WiFi to improve my location then the battery drain will be higher, but wouldn't that be dependent on if an app uses the location in the first place?
I mean, if I have my location set to highest accuracy and I leave my phone on over night, there should be no apps that would utilize the location services. Unless an app, for example Google Now decided to check where I am, I don't see the problem of leaving your location services set to high accuracy.
I personally use GPS only and I can confirm that no app triggers the location services during the day or night unless I open an app that requires it, for example Google Maps or a Weather app that I may be using the GPS to gather my location information. PS: I use AccuWeather and I have disabled use GPS for location and rather it uses my actual location based on my city and state.
4. Auto Brightness - although Samsung has one of the best auto brightness sensors for Android, there is much controversy (google it) that Android drains a lot of battery when using Auto brightness because it has to constantly use the light sensor to determine your screen's brightness.
When I got my GS4 I immediately disabled auto brightness and I manually control it, simply have 3 settings. I have 10% brightness for day time use, 100% for outdoor/car use, and 10% with screen filter set to 20% for bed use (late night and early morning). I will be doing the same with the GS6.
I can't speak entirely for auto brightness and whether it saves or consumes battery life, but from my research, people should just manually control it as opposed to using auto brightness, the exceptions are iPhones and Samsung phones.
Furthermore, during my testing, I ran a Geekbench 3 battery life test on my phone with the following conditions.
WiFi, GPS = On
Screen Brightness 10%
Bluetooth, Mobile Data, NFC = Off
Result = 2 hours and 55 minutes (screen on time)
Same test with screen brightness 100%, result = 2 hours and 45 minutes (screen on time).
This shows that in continuous use the real world difference in battery life between 10% and 100% brightness is only 10 minutes. Remember this is for the GS4. I am not sure how the GS6 will handle both extremes in terms of battery life for the screen brightness. My guess is that there will be little difference between using 10% and 100% in real world numbers like shown above.
5. Facebook and FB Messenger - you state don't use it but don't pose an alternative, let's be realistic a ton of people use it, by simply stating don't use it and not providing an alternative is somewhat pointless. My GS4 is rooted and I have been using BetterBatteryStats (BBS) for 2 years now and I can say for certain that FB does not drain the battery. However I can see that FB and Messenger do create a lot of Alarms, about 10 - 30 per hour. But when I look for Kernal or Partial wakelocks I see no correlation to battery drain.
I have even removed both apps from my phone and used my phone during a regular work week and I have found no real world difference in battery life.
However it is possible that FB and Messenger could have had a bug that caused battery drain, I have physically seen this issue with Viber and cross checked with BBS to confirm. But that was an old version of Viber, and since then Viber has been working fine.
I personally helped Jango Radio fix their battery drain issues. For example you open the app press the home key, then you will see that your phone will be awake for as long as the app is sitting in the background. I told the dev team to fix it and they did. I used BBS and watch the Partial wakelocks to confirm the issue.
Your final statement of using Gsam is fine, I've used it too, no battery life monitor is perfect, but at least they can help determine if there is a rogue app.
In terms of performance, I agree with doing 0.5x for all transitions, it does make a big difference. Less waiting for apps to close/minimize or open.
In terms of rooting and debloating with Titanium backup, that is something that rooted users can do.
I agree uninstalling system apps/pre-loaded apps will give you some space back.
Freezing an app versus disabling an app...well disabling should be good enough for people especially since you don't need root.
If you freeze/greenify apps versus simply disabling apps you don't need/use I'm sure the performance improvements would be identical, however I don't think there is much of an improvement regarding either methods.
A simple way to test this is to take a stock S6, run a benchmark, like Geekbench, and then root the S6 and freeze everything that is not needed and run Geekbench again. If there is no real numerical change in the benchmark, then I really doubt you will feel a real world difference in performance.
Let me know what you think.

5. Facebook and FB Messenger - you state don't use it but don't pose an alternative, let's be realistic a ton of people use it, by simply stating don't use it and not providing an alternative is somewhat pointless. My GS4 is rooted and I have been using BetterBatteryStats (BBS) for 2 years now and I can say for certain that FB does not drain the battery. However I can see that FB and Messenger do create a lot of Alarms, about 10 - 30 per hour. But when I look for Kernal or Partial wakelocks I see no correlation to battery drain.

Browse to Facebook on your phone using Chrome then go to chrome settings and press "add to home screen". Problem solved [emoji6]
I do this and get much better standby battery life. I can't part with messenger though, but you can access your messages from the mobile site too if you don't care about getting notifications.

Let's use the most powerful Android smartphone currently on the market as a dumb phone is basically the gist of the advice given!

Thanks for your tips. Useful for me

Just scored 29hours runtime i thought impossible in first few days. With just lux app and tasker auto sync only. No root.
Edit: with greenify too but i find it useless without root

Jesus, you've basically disabled your phone, why not just return it and go with a pre-paid flip phone? Listen I understand there's definitely a battery issue with the S6 but come on guys, just have a charger with you until this is addressed via an OTA update or something.

Using GSAM, how do I see Wakelocks and how do I see Deep Sleep?

I am optimistic about the development department of Zenfone, atleast they are working deep enough about their flagship. The battery drainage is an issue for almost every Android L(5.0) user. I hope this issue will be fixed after we get update for 5.1.1 .
Asus is also expending their QA inspection team this will help for the end user to have stable releases afterwards.
Thumbs up Asus for the efforts.

I just received my phone this morning. it's a CN model. I charged it to 100%. Played a bit with it at work when I had the chance. I've spent the rest of the evening setting it up. The latest update is sitting waiting for download but I won't take it until tomorrow. I want to see how it goes overnight.
Even given the short time I've had it I'm pretty sure the battery stats are simply misreported and the poor battery life that some people are experiencing are down to individual setups or faulty devices. I've done nothing yet to conserve battery other than turning off the stupid ASUS battery saver, deleting some Chinese bloat and setting Wi-Fi to switch off when screen is off. From what I can see battery is comparable to my G2 which I was very happy with. As you can see from the screen shots it's pretty good.

so does this mean your device is running on CN firmware? so maybe the biggest culprit for battery drain in WW is google playstore and other gapps, because CN firmware didnt preinstalled with gapps..

Trust me. The battery life is aweful and is not just down to user error. I've used many, many android devices set up using similar parameters. Wether android 5.0 is to blame or something else, it is not my user error causing my excessive battery drain.

Um, even with Android OS battery usage at 21% and screen at 12%, according to batt stats screen, I still managed around 5.25hrs SoT.... With 32% battery left.
Granted this is just from last night to this morning and is mainly just Web browsing and playing some music (was up late couldn't sleep!). WiFi/Bluetooth/GPS/autosync on.I've frozen/disabled most pre-installed apps and services.

Glad to see updates with Google Voice, I've had some issues with outgoing calls not using voice.

I am not jumping to conclusions... Merely stating the obvious statement made by Asus... Secondly.. I believe in Asus and their commitment to this device .. But building up another wakelock is not the way to go IMO..

Yes, that's why I'm running with CN for a while. I don't have to have google apps as system apps. Once I have a setup I'm happy with I'll back up and test it for a while with them moved to system to see if there is any difference. I'll then switch to WW and compare that. (I'll also pick up my google drive offer at that stage.)
It has lost about 3% overnight so it's heading for about 6 - 7 hours SOT. I'm guessing that that will drop to about 5 hours in normal use given other people's reports.
I've already ruled out the android OS in battery stats as causing any real drain. I've encountered this before with a previous device. All the manufacturer did was adjust the way battery stats was reported. There was no underlying bug to fix.
I'm taking things slowly and methodically with setup so if I do run into any real battery issues I should be able to easily identify the culprit(s).
I'll take the OTA some time in the next day or so and see how it compares. I'll feed back in this thread but I guess the WW update will be out by then.

Sultan CM13 : How to optimize SoT and battery life

Hi,
I'm reading a lot of thread in this forum and I tried a lot of advice but my problem is still here.
I have my opo since ~20 months and I have some troubles with my battery life. I use Greenify with package donation and Amplify. This helps me to keep some percentage of battery but I'm not satisfied of my SoT (I know SoT is not a good mesure). I can only reach 4h hours MAX on screen and an average of 3h30. Battery is discharge after ~9h30..
I'm playing Clash Royale and Clash of Clans for 1 hours, Google Chrome for 45min, Youtube 30 min, Textra 15 min and rest of time WunderList, myMail, Snapchat and PowerAmp for music. Swiper is draining app but this problem was here before I use this app.
I never use location, 5 min of bluetooth and on LTE all the time or sometimes WiFi. I try to be in Battery Saving Mode when I reach 50 %.
I use Better Battery Stats (but i don't know how to use it) and GsSam Battery Monitor (for more statistics)
Screenshots
I tried to change to Darkobas rom but camera was totally bugged and i dislike non cyanogenmod rom ..
I try to change change the kernel and finally this bricked my phone (lightning kernel). After a backup, I search an other kernel but I doesn't found an other kernel who could be compatible with Sultan CM13.
I'm really nervous with my battery and if anyone help me to reach 6 hours SOT, I can donate 5 euros with Paypal or more if it's worth..
Thanks for your help !
Edit : I flashed private kernel r15 on my device and use Kernel Adiutor to apply some change :
CPU max : 1190MHz
CPU Governor : smartmax
GPU max : 200MHz
And I was able to get 5 hours of SoT and 13 hours battery !
Thanks for help ! (especially for fafa77140 and Renosh)

Would you like to post a list of your installed apps? The causes of most battery drain are mainly due to apps, signal strength and screen brightness.
If you want to reach 6 hours SOT, playing games won't help . Also, the more you stick to WiFi instead of LTE, the better your battery life. Use GSAM to check which apps are causing the highest battery drains and post your screen shot here?

I don't know if it can be checked with some software. The only thing I can tell you if you want to check if the battery is fauly is to buy another one and replace it.

Use greenify without Xposed. I got 6-7 hours of SOT with no problems. Running latest Sultan CM13. Even with no cpu underclock.

Probably lots of Wakelocks caused by other applications all well, which is causing drain during screen off. I suggest you uninstall apps you don't need that have push notifications. Or you can turn off push notifications for apps that don't need them

The biggest reason is mobile radio active (MRA) bug in all lollipop and marshmallow ROMs and I don't know why people are rushing behind **** LP and MM ROMs. MRA can only be resolved by Google, but it seems that it is not hampering the Google revenue, so Google have kept it as a low priority till now... very sad and shame too.

Try using PowerNap, I've had very good results using it

Try in KA --> CPU --> max 1497 ; min 300 ; gouv smartmax-eps ; sync 300 ; enter boost 1497
I/O --> row 1024kb
And if your kernel in your rom don't have it install Lightning kernel caf without coloros blobs and it should be right

Playing games for 1 hr or more a day will kill SOT. Try rooting with SuperSU and under clock GPU to 200 MHz using kernel auditor. It will help to increase battery life as GPU is very battery intensive, it won't affect COC or CR. If you want kernels you can try Private Kernel but its not necessary. Using mobile data also uses more battery than if you used Wi-Fi.

The ROM with most SOT for me was Marsh CM13: https://forums.oneplus.net/threads/marsh-cm13.405700/
I was getting average 5 hours of SOT (other ROMs was about 3.5 - 4), on the stable 1.9.7 release: https://mega.nz/#!5xNhXQJB!4HwnbLANCmgno9DJJpxIbiBkL_tg19JSLtvNQrpeVjs
After 1.9.7, you need to flash Pico package of Open Google Apps, I've haven't used it since so I can't recommend.
Oh and if you run into troubles flashing the build, try Unofficial TWRP 2.8.6.0.6 by kumajaya: https://www.androidfilehost.com/?fid=23991606952609056
