Hi, ever since my device was updated to Android 5.0 about a month ago I'm experiencing a significant decline in battery life.
Before the update, the battey usage level page under the device settings used to be quite stable and I would get up to 6 hours of screen on time a little before the battery was emptied. (With approximately 10% battery left)
Now, after the update, I get roughly about two and a half hours of screen on time and the graph on the battey usage level is falling steadily. I would note that according to observations I made with the cpu spy app the device is in deep sleep most of the time when I'm not using it. I'm running stock rom and without Root. The wifi or the data are active almost all the time (respectively), and the location setting is "battery saving". Sync with Google services partially works for services I need throughout the day.
Any help will be appreciated, thanks in advance.

Thank you very much
i'll try it as soon as I reboot my device tomorrow morning and I will report if it helps.
I have a SM-T800 on CM12.1 that averages a current drain of around 60 mA during deep sleep. I also have a OnePlus One that averages around 9 mA during deep sleep.
I'm using Battery Monitor Widget Pro with the "Android mA" setting to get my readings on the SM-T800.
Obviously, there's quite a difference there. The SM-T800 draws almost 7x as much current while it's doing nothing - no screen on time.
It makes me think that there must be something I can do to reduce the current drain, especially with a rooted device. But, I haven't been able to figure out what.
Has anyone been successful getting their battery drain lower? If "yes", what have you done?
Thanks,.

Did you forget the thread you made 2 weeks ago.

Yeah, @Tinderbox (UK), but since the title was messed up I didn't think folks were looking/responding/searching to the older thread.
I think this is still something we can all benefit from, if someone has figured out a way to get our power consumption down. And if someone does respond back to this thread, other folks will be able to find it when they search now.
I use Euphoria OS and debloat it, that gives me a few weeks of standby if it's just sitting on a shelf. Ensure you delete Trebuchet (replace with Nova/Apex/etc) as it sucks a huge amount of CPU power when idle.
If you can run without GApps you'll maximize the savings.
As i said last time my T800 only used 1-2% in 16hours what ma does that work out too, the battery is 7900mah
7900mah/100 =79/16*2=9.8mah
Every time you install an app, it can make an huge difference, if it stops your tablet from sleeping.
You need to check your wakelocks to see which apps are keeping your tablet from going into deep sleep, auto check for emails, sync, alarms will cause your tablet to come out of deep sleep.
John
Thanks, @Tinderbox (UK).
As a test, I decided to wipe out my current installation, and just load the latest Nvertigo SM-T800 ROM and the very minimal nano Open GApps. I had to load a few minor things beyond that to get functional (KeePass Droid, Opera, MyBackup Pro, Wakelock Detector). I disabled all Google account sync items.
I disabled Trebuchet wake-ups, and set autostart off (Thanks, @fraser.dk)
I'm still seeing about 1% drop every 4-5 hours.
Nothing stood out from Wakelock detector. After 24 hours of the tablet sitting idle, the wakelocks were all less than 30 each.
Are you running a specific ROM or Kernel?
I am on the Stock UK v4.4.2 kitkat rom, I have never flashed though i am rooted.
If you are rooted, try the app in the link below, it link to XDA and you can download a version of cpu spy reloaded, it works great at spotting wakelocks it`s the only wakelock detector i use now.
I am running an Sony App that is supposed to stop all wakelocks, it`s in standby mode, you can whitelist apps if you like, I am not certain if it`s doing anything at the moment, you need root and exposed installed.

A 1% drop over 5-6 hours is not bad.
John.
So i have an result on the Sony Battery App, I put my Tab S into sleep mode at approx 12:30AM it was at 69% , I woke it up at 6:50pm, it was still on 69% after 17hrs.

for me i have downgraded back to stock kitkat 4.4.2, debloated, rooted and xposed installed, and use powernap, i can use the tablet all day and still have between 45% - 60% battery left depends on if i am playing games or not... i have tried so many apps and custom roms in lolipop and none of them have good battery life....
PowerNap which is the Sony app i use, only reduce battery drain in sleep mode, by stopping all wakelocks, it does not reduce the power that games or other high drain app require, so how does you battery last longer, how much power were you loosing overnight when you tablet should have been sleeping it must have been immense.

on kitkat i had no major battery drain, i just like having powernap on my device... on LP like i say even just using the tab battery would drain like 1% every min... just doing typical web use... i have tried everything to get good battery life on LP but nothing works for me at least.. but with KK i have no issues...
A lot of people say they have had no problems with lollipop, but there is an significant number that have reported problems after upgrading, I decided to stick with kitkat and await android m.
1% a minute just browsing that`s bad.

I think I'll try going back to KitKat, and see how things go.
I have been frustrated on how fast the battery drains when doing minimal tasks, like reading an ebook (about 1% drain a minute).
Downloading KitKat from Sammobile now.

that how it was for me... 1% a minute.. i like kitkat and very happy with it does what i need and awesome battery life..
Bummer.
I installed the Canadian stock KK ROM (T800XXU1ANJ6_T800XAC1ANI1_HOME.tar.md5) onto my US SM-T800, and it's boot-looping.
I thought I should be able to load the Canadian version without any problem.
Is there a way to turn the tablet off when it is bootlooping? I don't want the battery to drain while I'm downloading another ROM.
Try this to stop boot loop.

Thanks, @Tinderbox (UK)!
Out of the bootloop now, and setting up KK.
What do you do to prevent OTA updates? I have TWRP installed via the All-in-One Auto Root.
If you are rooted you will not get ota updates, if you are not freeze the updater an tab s owner did that with an app called "package disabler" it works without root but the free version keeps being removed from google play store, the full version is £2 (£1.50) just reduce.

@Tinderbox (UK) WHAT KITKAT ROM YOU ARE USING ????
stock UK kitkat rom v4.4.2, Lollipop has been out for my T800 10.5" for an couple of months, but it is full of bugs, and quite a few people have went back to kitkat.
Kitkat has been solid for me, I ran it for 164 days continually, I never rebooted or shutdown in that whole time, no problem at all.

Hi guys i have my pixel 3xl and my battery is drain too fast when i dont use it in night fo exemple a left him 100% after 6hours i found him 70%
I chek if thers is an app in background and nothing i Factory reset it 3 times and same thing
Let it drain down to about 10%, and then check the battery stats to see what is high on the list. I get less than 1% an hour, and have for the longest time. Running Android 11 since beta 3, and now official.
Hi! I got exactly the same thing with my Pixel 3 and got the same issue, it seems like our device cannot deep sleep. Here is my battery usage and wake lock on EXKM (Running latest Kirisakura, screenshot attached)
Also mine, last night it was 100% then this morning, when i checked it, its already at 95%. Also i noticed that my 3xl now is draining too fast, any tips on regarding this to save or extend my battery? Thanks guys
First week(nearly) after factory reset or flashing img your google play services should drain too much battery which is normal as settings are calibrated, usage patterns adjusted, small updates installed etc.
Most battery issues are related to some rogue app, bad signal reception(it does not need to be full bar, even selected frequency by carrier or phone) or confused google play services. If it is google play then root needed to find root cause(pun intended )
For my case a full day with 1h+ gaming and whatsapp, phone and other stuff 4hrs sot and generally less than %20 percent battery at evening to start charging. You should be happy if you are near this values.
Hi! Thanks for the insight, I'll try to wait until a week and going to post an update here! Just curious because I can't find any information about the kernel wake lock that constantly occurring on my new phone
Edit 1:
So after a few days of searching, I found out the one who cause the deep sleep issue was my modified settings for the Entropy (I modify it via EXKM), after I set it back to default the Deep Sleep issue completely gone and I can stay 0.2 ~ 0.3%/hr when the phone is Deep Sleeping
I hope my issue can help you, and try to reflash it via fastboot with the latest (Android 10 / Android 11) pixel image just to make sure that there is no corrupted data
Hi all,
I have a couple questions.
is it normal that other apps use so much battery? in 24 hours it drains around 650 mah, and in 2 hours it drains around 60 mah or so. I attached screenshots showing this (sorry for bad quality and long screenshot)
and sometimes after charging my phone and unplugging it battery percentage doesn't go down for couple of hours. for example with 20 min of screen on time and 2 hours of idle it should go down about 5 percent or so but it doesn't even go down 1 percent.
Using miui 12.5.1
i don't think it's normal at all, I too have noticed excessive battery drain by "other apps" both with the official rom and with xiaomi.eu ROM. I really would like to know what these "other apps" are so that i can disable them because the battery drain is really high on 11 lite.
It's a pity, i like xiaomi.eu ROM but because of the battery drain I decided to change the ROM and now I'm on Xperience ROM who doesn't have this problem but some important features are missing like DT2S and fast charging.
Guys, if anyone has solution for battery drain please share it whis us .
Regarding your problem with the percentage not going down, sorry i can't help you but i never ran into this problem.

Completely agree with that. Just because of that I started to uninstall apps that I use less in order to see if "other" battery usage will decrease.
Same problem here, but I don't have any clue which app causes this behaviour. Someone still on 12.0 with the same issue or is ist 12.5?
after deleting some apps (or after a while) this problem got better. now I have 250 mah in 24 hours on other apps. But now for some reason google play services started to drain much power when not connected to the wifi (or i just realized this now). It drains 1% battery in 1-2 hours when wifi is off but its normal when connected to the wifi. This is an interesting problem as well. any of you encountered it?
