Battery drain 100% (device doesn't sleep) - Samsung Galaxy Tab S3 Questions & Answers

Hi everyone,
Just I've purchased this device I came across with the 'battery drain' problem. I've read and done all possible suggestions, like switch of location services, sync, disable wi-fi/bluetooth, etc. But that didn't help. After that rooted the device and installed TitaniumBackup, BestBatteryStat, WakeLock Detector.
TitaniumBackup: many services like Knox were disabled (I also found list of useless services, so I disabled a lot of them).
With BBS and WLD I've been measuring that is going wrong. Did anyone have the same problems? I can't public links to images here yet. I would appreciate if anybody know what the problem might be.

battery drain Google maps

For a few days now I've noticed a massive battery drain of Google maps, up to 60 per cent of the battery use, without evening opening the app (must have been running in the background). I have temporarily disabled the app on my phone, but am I the only person with this problem?

Make sure the "Location reporting" (in Google Maps settings) is disabled if you don't want the battery drain. Moreover, Google Now activates the Location reporting so you might have to disable Google Now as well...
P.s: this post should be in Q&A section, doesn't it ?

I have google now disabled all the time, and the location reporting was unchecked too.. Besides that, even if that had been activated, it shouldn't have taken 60% of my total battery (I had about 70% of my total battery left when I noticed it today), should it?
(...and yes, this one should be in the Q&A section, hadn't thought about that when I posted it though...)
I had the same issue. I turned all location reporting off and turned off Google now, also made sure GPS was off. All that helped a fair amount but Maps still kept running in the background even though I'd never used the app. In the end I used an app called Greenify to hibernate maps and a bunch of other background apps and it made a world of difference. Use wakelock detector to see which apps are causing wakelocks and disable any you don't need running.

use an extension car battery so it can add battery life even for month, just make sure you will get the same voltage
Its coz of google location services bug that HTC phones are having after the update.
If you are interested about it: http://www.androidpolice.com/2013/0...ssues-for-htc-owners-google-working-on-a-fix/
In short:
Only location service thats working if you have this bug, is gps. Rest of locations services (wifi, mobile newtwork etc.) wont work.
Who couses it? - latest updates for google services.
How to fix it? - atm google is working on fix. There is some type of user fixes you can try. (see post).
Hope it explains your drain. I have this bu and i get this unusual drain from maps too.

[Q] Google services - high data usage = battery drain

Hi, I have a stock i9300, rooted.
About 3 days ago, I noticed that my device, which normally gets through a day comfortably, was running out of juice by early afternoon.
I've checked the data usage meter and it shows that Google Services is doing something with data constantly. It's not a lot of data (500MB over 7 days) but it's enough to keep my "H+" showing data uploading and downloading all the time, which is not normal behaviour.
As a result of this, the battery is running dry. Even when plugged in, the charging isn't keeping up and eventually the battery runs out, and I have to leave the phone off for a bit to recharge.
I have since turned off background data for Google Services, and I'm hoping this works, although I don't know what I'm going to lose in terms of functionality as a result of doing that.
But I'd like to know what the problem is and why this has suddenly happened as it's really bugging me. Hoping someone else has experienced this. I have searched for other threads on this topic, all refer to battery drain but I don't seem to have the same issue. If I look at my battery stats I'm not seeing Google Services at the top of the list like others. Mine is more to do with data.
Cheers,
Pete
I cant answer why or what it is, but one thing I did notice wasted a lot of battery for me (other than google now of course) was the google backup. You know the one you tick when you first go through the set up wizard on the phone? "Backup this device with google".

hi,
if you have various system or user apps wakelocks, first do a monitoring it with your favorite battery monitor and analysis tool to details.
gmail, google services, backup, sync contacts, other syncs google plus, etc, localization services, call direct or indirectly other apps, bringing more wakelocks (partial, kernel, network - your case I think) ... and more battery drains ... facebook is a classic example ... hungry app
Wakelocks - read it ... enlight your questions
http://forum.xda-developers.com/wiki/Wakelocks
to monitorate and analyse the battery consumption, drain, and wakes use BetterBatteryStats - bbs
[APP][2.1+][16 Apr. - V1.13.4] BetterBatteryStats - thread
http://forum.xda-developers.com/showthread.php?t=1179809
you can use traditional battery savers (i didn't recommend)
I do use greenify together with bbs (paid app - to full hibernate and extras, but very good - the "engine" is different, doesn't kill or freeze, but hibernate system (need root) or users apps. @oasisfeng created a smart and reliable engine - support him
[APP][3.1+] Greenify *ROOT* v1.85 beta 6 (Updated on Jun.6)
http://forum.xda-developers.com/showthread.php?t=2155737
increase my battery and decrease unnecessary wakelocks ... excellent results ...

[Q] Battery Drain when changing permissions with App Ops

I have recently been taking control over the permissions I allow with certain apps with the use of App Ops starter that was included with my LG G3 Android 5.0 update.
I have noticed however that since I have disabled certain permissions for certain apps the battery usage for those apps intermittently skyrocket to using 30% in under an hour at random times. This often happens while the phone is idling and with those apps not even open in my task manager.
Some examples would be disabling the location data for apps such as Facebook's "Messenger" app and also games like Wooga's "Diamond Dash". Google's default "Maps" app is also a culprit after disabling access to contacts/phone.
My guess would be that these apps are stuck in some loop constantly checking for the information they no longer have access to.
Can anyone comment as to having similar results? Can anyone make suggestions as to possible things I could do on my end?
I have tried to re-enable the permissions to verify the results however as this is not an issue that affects the battery constantly but only intermittently I'm unsure as to whether I am right in my assumptions and there was one instance where I had re-enabled all the permissions for Facebook's "Messenger" yet it still consumed significant amounts of battery while being closed and the phone in it's idle state.

You are right on why it's happening. If they can't get the info they are programmed for then they keep trying. Not a whole lot you can do really. As long as they are programmed to try and get the info then they will keep trying.

[Q] wakelocks: how to identify which app is calling a given process?

I am having lots of issues (have had to reset it 3 times over the last 10 days!) with my Sony Z3 running KitKat, but I am posting here as I see this as a generic, non-Sony specific question.
I am rooted and use BetterBatteryStats and Wakelock detector to identify partial wakelocks. I have had to reset the phone 3 times over the last 10 days because of mysterious processes locking the CPU, draining the battery, overheating the phone, and also because the play store stopped working (always stuck at 'download pending').
My question is: I can use these (and other apps) to find the services which are causing wakelocks, battery drain, etc, but is there any way to find which apps invoked the services?
If I find that app X is misbehaving, well, I will try changing the settings of that app, or consider removing it. But if I find the battery drain is caused by, say, google’s location service, that’s not particularly useful because a number of different apps may have called it. Was it a wether app? A public transport app? Was it just Android going nuts? That piece of information is basically useless because it doesn’t tell me which app is the problem.
Thoughts? Any help would be greatly appreciated!

Screen/Display drains battery horribly while being switched off!

Hi everybody,
I am using this ROM on my RM Note 2 prime ATM since I need some newer Android version than MIUI on this phone offers (5.0) especially for several apps that are necessary these days but need newer ROMs.
But for whatever reason the display battery is draining horribly during night while everything is switched off (13%/hr)! Could not identify the problem yet. Any idea about where to dig in or where to check for root causes? Already using GSAM Battery Monitor + Naptime and PIE internal aggressive battery saving settings but no success. In addition I deactivated lots of background apps and services I do not need but with no effect too.
In addition Kernel drains some battery according to GSAM but for the listed services I could not find yet anything to decide upon what to deactivate. In addition the wakelock blocker of this ROM shows me lots of entries but I also could not yet find any explanation or hints here or in the web which of those I can safely deactivate. Any idea, hint, link or tip highly appreciated.
Any help, hint, idea etc. highly appreciated!
Thanks in advance!
