Battery drain (idle) - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

So I bought this tablet a couple of months ago and was always amazed by its battery. I could leave the tablet on for days and days that the battery would hold without any problems.
Suddenly and out of nowhere, I started to notice battery drain while the tablet is idle. I would charge it at night and next morning I would have less 30%, something that never happened before. This with Wi-Fi off and pretty much everything else. I know there's always consumption but these numbers don't make any sense.
Recently 7.0 came out, I decided to give it a shot to see if it would fix it. Did nothing, tablet is exactly the same. After installing the new OS version, wiping data and cache, disabling all the unnecessary features I could think of.
Also tried to go back to stock 6.0.1 and the problem is still here. Since nothing helped right now im back to 7.0. I have no apps other than the stock ones and I'm running out of ideas here.

Mine too, on 7.1.2 Nougat custom ROM drain like hell even if the tablet it's shutting down, charged at 100 % in the evening and in the morning after boot remaining only 75 %.
Clean install with wipe and everything !
I don't know what's causing this behaviour !

Haven't been here in a while, sorry.
I tried everything and since nothing fixed it, I contacted the store and used the warranty, they sent me a new one. Apparently it's a known problem and they were very quick stating that it couldn't be fixed.
Maybe you should try the same, if you haven't already..

I have the same issue they said battery life has improved since Lollipop yet in the 36 hours I have had it I have had nothing but extra battery drain to the point I have just reinstalled Battery Doctor to kill unwanted apps running in the background and to examine what app will consume more power then it should

I am still trying to work this one out, removing Facebook app helped a little but not enough, Battery Doctor has also helped but only around 10-20% improvement from the sudden poor battery performance.
BTW I am currently running the Baltic generic version 23.1.A.0.690 of Lollipop 5.0.2.
So apart from the last resort of doing a factory reset it is a work in progress
my university
I think I may of sorted my battery issue but will know for sure in a few days.
I reflashed back to my providers Vodafone UK stock KitKat firmware and got the Flashtool to wipe the data at the same time I had to do this because for some reason I had lost gyroscope, accelerometer and compass. The I reflashed the Baltic Generic Lollipop firmware also wiping the data and in the last 24 hours since doing it the battery performance looks to be much better and after 5 hours from last charge I still have 1 day and 6 hours remaining
UPDATE:
Looks like I may of sorted my battery drain issue.
My phone had a full charge from 3am-1pm (don't ask why 3am when I wanted to go to bed earlier then that) after 3 and a half hours I had only dropped 4% and still had 4 days left and then had about half hour of game play using bluetooth to my PS4 controller and still have just over a day's charge left although with lower usage this evening will probably improve.
When I had first installed Lollipop beforehand I couldn't get more then 12-15 hours between charges.
I thing I have forgot to mention was a bug I noticed before wiping and reflashing with Lollipop.
The night I decided to wipe and reflash I had noticed 2 things, first was that the accelerometer, gyroscope and GPS stopped working and then the 2nd thing I noticed after deciding that I could wait until the next day to investigate the first issue was that even though the screen would turn off the backlight remained on which made me decide to do the flashing that night instead of waiting.
But I have been thinking that wiping down and reflashing back to KitKat might not of been needed and could of just wiped down and reflashed Lollipop which could of saved around 20 minutes but due to the first issue I thought it best to go back to a known good firmware first
15 and a half hours so far with 16 hours remaining,
So an estimated 31 hours since reflashing I think it is looking like this battery issue can be solved by doing a CLEAN FLASH of Lollipop

Extreme battery drain

I've been having this issue for weeks now. Battery life is only 6hrs. I've tried another battery, turn off WiFi, GPS, NFC, Google now, reboot, reset, and everything online about this issue.
Attached below some images from the battery status as I hope it might help!
If it may count, I use LG Smart cover!
Can someone give an actual reason to this issue even if it have to root the device?
Thank you!!
how long u been using the phone?
Today, for about 4hrs, 1hr SOT.
Total time the phone with me is about 6 months. More or less.
What if you don't use the cover?
I've also had this issue before. It completely gone after I did hard reset but it came back now after the cover. I tried hard reset but restored data and apps using the setup wizard and for some reason, maybe the restoration, the drain didn't stop this time. But I really don't want to reset the phone ever other week!
Had this issue my self, tried EVERYTHING, nothing helped. (hard reset, rooting, various ROM's)
Sent it in to service, where they changed battery, mother board, back plates, and the lower part.
That helped, now I can almost go 48 hours on one charge, with fair usage.
So basically I get a new phone
I observed that I have this extreme battery drain too since Facebook and Messenger drained hard the battery because of a bug one or two weeks ago. And then I remembered that I installed Greenify on my Nougat ROM. I removed Greenify : no more battery drain !!!!!!!
Thanks for the reply. I don't use greenify at all. I'll try to remove Facebook and messenger maybe it will help. The thing is my mother also have the same phone but the Israeli version, not European version and none of this bullcrap is effecting her phone!

Battery Percent

I have started getting a Battery Percent that keeps defaulting back to 40% it shows 100% when charged, but then eventually reverts back to showing 40% I have tried wiping cache, but it keeps reverting back.
Might want to specify which ROM version you are running...
Mine’s still great. I charge either once every night or every other day during the night time.
(Boy that Mate 10 Pro Porsche Design looks nice!)
Oops!! Guess I should have put this under the Nougat thread. I'm running the latest lineage 14.1. The funny thing is I've been running it for a while now with no issues. I replaced my battery a few months ago, the new battery holds a good charge and haven't had any issues with it. So if I reboot my phone again it shows the correct battery percent, but after a few minutes will revert back to 40% every time.
That’s not a problem where you post, just wondering if it is a bug with the ROM/OS, or the new battery, because I have been using this phone for years while my wife and son still struggle with the puny batteries on their iPhones, which are even newer!
I still run the 5.1 from Huawei. It may have degraded but still so large in comparison I can’t feel a difference. Definitely doesn’t ever jump at all that I notice.

Im running the latest lineage-14.1-20180119, and have been since it came out. I think it might be something to do with battery, I have the same phone for my wife with the same rom and no issue on her phone.
I have the latest Lineage as well, but I do not have this problem. Does it ever get below 40%? If so, maybe try letting it run out completely and then do a full charge from there?
Yes once it gets to 40% it starts going down or if I plug it in it will show the correct percentage.

D6603 - Battery draining like crazy - nothing helps

Hi. I regret having bought this particular model. I already had a D6633 which was working perfectly. This time, the battery goes down like stupid. It can use 50% within 10 hours when NOTHING happens. While I'm using it, it goes down as fast as it charges, not to mention the phone running burning hot. I tried virtually everything - calibrating the battery, kernel tweaks, forcing deep sleep, swapping the battery, running different optimizations - nothing helps AT ALL. I assume it means the phone is about to die any moment, but is there any way to make it discharge half-decent?
Similar problem with my old Z3 now also.
I suppose the battery has just gotten old and needs to be replaced?
Post is quite old, but in case somebody searches for an answer - I dealt with that. Tried even more things than OP, but in the end I have backed up most important things with Titanium Backup, went to recovery, wiped everything, installed a fresh prerooted 5.1.1 from scratch, restored the backuped things, installed my own mods that I've used on the previous system, installed missing things from the Play store and not only the issue disappeared but also the phone became way, way more responsive.
Previously when I disconnected phone from the charger in the morning, I had to charge my phone around noon because it could die on me in the afternoon.
Yesterday I have disconnected it from the charger around 3 PM and after over 24hrs, before I started messing with xposed mods and had to constantly restart the phone I had around 60% battery left. Now, after an hour of playing with phone and quite a few reboots, it's sitting at 47%.
tl;dr - don't try to fix that, it's highly likely that it's broken at OS level and even if it's not (and I highly doubt that, app usage before/after is at the same level but battery lasts few times longer), it'll take A LOT of time, way more than setting things up from the scratch (and if you use TiBu, it's something that can be done in an hour or two).

Close to terrible battery life

Helllo guys!
So here's my story: About 6 months ago i installed this https://forum.xda-developers.com/lg-g5/development/h830-resurrection-remix-6-0-0-t3792258 Ressurrection Remix mod and I was absolutely loving it. Now I started to play Pokémon Go again with colleagues but since my device was rooted it kept crashing so many times that I decided to switch back to stock rom, also in this case I wanted to get my 60FPS video recording possibility back since RR didn't have that function. My battery life was absulutely okay when I had RR, like with normal daily usage i could hold out for 1.5 days without charging it. So basically I flashed back to a stock ROM using a zip from one of the thread around here called "LG-H85030a-Flashable.COMPLETE", though I wanted to be up to date with the ROM, also this flashable was Vodafone and I needed an original T-mobileish ROM. So I tried to update the ROM with LG Bridge which was a success. Then I knew I had to root it one more time because of batterystats. So I rooted it again. Deleted batterystats, discharge then full recharge without any intervention and of course while the phone was off. After this I kept experiencing a massive loss on battery life. Like while playing Pokémon GO the phone discharges 15-20% in 30 mins of gaming. I know that Pokémon GO eating up battery since it's release and maybe they still din't optimize it. But what it's wierd that I just charged my phone to 100% then I went to take a shower which lasted about 20 mins and when I got back I saw that the battery percentage dropped to 92%. In freakin 20 mins idle time. Is it possible that I did wrong something in the batterystat reseting? I did it many times before and I didn't have any issues after it. I also tried to calibrate the battery with the Advance Battery Calibrator app (https://play.google.com/store/apps/details?id=com.newagetools.batcalibra&hl=en_US) multiple times and I didn't have any luck. :/ Also tried to remove or freeze some applications which were running in the background and they were useless to me. Or maybe is it possible that the ROM i downloaded and installed from LG Bridge is a complete ****? Also FYI I have two batteries, one which came with the phone ofc and one which I bought a year ago within a charging kit. The phone itself is about 2 years old. Basically the original battery should be closing to it's ending but the other shouldn't, also I tried the calibration process while I was using the fresher battery. Also the current ROM version is 8.0.0 Oreo, v30c-216-30 if that helps anything. :S I also installed the MK2000 kernel because after rooting the phone the flashlight didn't work and the MK2000 fixes that. Though the battery life was bad before it too, so that can't be the problem, the fact of the root either because even the unrooted ROM had bad battery life.
Thank you for your further help guys!
