[Q] Why Battery Draining Fast?

I have owned this phone for about 3 days, but I have some battery issues.
I attached 3 pictures, and on the first picture, you can see there appears to be no wakelocks, but on the 2nd picture, the Android OS used the vast majority of my battery life, and the 3rd picture, Android System has a lot of "Wake Up Device" (i don't know what the number means is it minutes?)..
I have uninstalled/disabled most of the apps I don't need, and have the brightness set to low, and on airplane mode with all sync off, and zenmotion turned off, and this still happens. I lost about 11% battery overnight with this problem. It seems like when I am using the device, the battery drops a percent every minute even when I am just scrolling through the Settings.
I only used about 1 hour screentime on this phone and the rest on idle.
I already installed both system updates.
Does anyone know why this happens? I know there is a memory leak problem, but I saw on another thread other people don't have that bad of a drain anymore...

For battery draining assistance see ZenUI app called ASUS Support: Apps/ASUS Support/Assistance/Battery/Battery drains fast/follow detailed troubleshooting steps. If battery still draining, recommend updating to latest firmware version and then performing a factory data reset. Please ensure to back up all important data as this will erase all data.

Mine seemed fine for a week and then I got this today. Pretty much done with it. Can't even get it to factory reset.

hello guys i am getting screen on time of mere 2 hours without any significant use on my ZF 2.... i have stock rom. no root nothing.... can anybody help me

Battery drain issue still not fixed with updates???

Disable PC Link and Party Link default apps, worked for me. They're default apps using cpu all the time like they're SO Android... Disable all default apps that you don't use too

I've got here two brand new models, which differ only for touch and battery version (Z2C3 01040005 1525 and ... 1526)
The 1526 doesn't show any drain. The 1525 does, as of its very first boot. I tried keeping same settings of course.
I'd like to point out that when connected and charging it shows big steps like going from 63 to 72% and it also reaches 100% in less than 60 mins.
When disconnected the discharge path exhibits about 1:15min of operation.
May I suspect the battery is defective?
PS: after a factory reset from recovery seems have fixed the problem for now at least...

Asus Zen phone 2 laser battery drain ?
I made an account with this website and took the time to write this, so I can let users who own this phone know one of the
biggest battery drain features I've found......DISABLE HOMESCREEN APP MOVEMENT SENSOR, in app icon settings.
When you tilt your phone app icon adjust to the tilt, yes looks cool until you realize how much battery you could save by leaving then static and not constantly running a fDucking tilt sensor.

What do you do to reduce your Tab S power drain?

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.
http://www.xda-developers.com/optimize-battery-life-with-this-useful-app/
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.
Click the link below, to see an screenshot of GSam Battery Monitor.

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 have been frustrated on how fast the battery drains when doing minimal tasks, like reading an ebook (about 1% drain a minute).

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.

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.
John.

@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.

[Q] Battery drain after Marshmallow update

So I updated to Marshmallow on my LG-H815, and now my battery drain is a lot higher than on 5.1.1. I'm checking GSAM and it seems like Android System (logd) is using up the most battery.
The phone is running quite warm as a result, before, at the end of the day, my phone would be on around 60%, now it gets to 20%.
I can't seem to find much about logd, but so far I've disabled WiFi scanning, and checked to make sure Activity Logs is disabled.
Does anyone know what could help to bring Marshmallow promised battery life improvements?
Cheers.

I had a battery drain because of Bluetooth. After disabling it it's gone. It's only temporary solution because I need BT to use my SW2 smartwach. So LG do your job.
Wysłane z mojego LG-H815 przy użyciu Tapatalka

First thing is to do a factory reset after you upgrade to MM, my battery was worse until I bit the bullet and reset it. Now I get 2 days use with 5hrs screen on time, most of that on GSM data.

my experience with MM
Mine just updated to 20c (EU - Latvia) and its flawless! Had some battery drain at the beginning, now after 3 restarts it runs a lot better and battery life lasted around 15% longer! If someone have issue with processes called dex2oat as they running and eating up the battery, you will need to reset your phone to factory settings, reinstall all of the apps you had on Lollipop and restart phone few times. Mine disappeared next morning. I guess they were apps still optimizing for battery! Hope it helps!

My experiences with MM are:
1) Bluetooth drains THE **** out of our devices. If you don´t need it, disable it. No idea why, but with BT off, I have over 1 hours of screen on time time more every day.
2) Disable auto-brightness. Do it. Helped me to get from 2,5 h SoT to over 3,5 h.
3) Greenify really works for me. I know we have Doze, but Greenify affects system apps...maybe thats why. Or maybe it´s just voodo, idk.
Still, battery life could be A LOT better.

Well I've just done a factory reset, will see how tomorrow goes.

No improvement after a factory reset, may roll back to 5.1.1

In my case I did update from LL directly, battery was a disaster, disabled location services improved a lot. Found out how to do CSE installation with LG UP, reflashed the phone and disabled location services, battery is great...I end up the day with 40% with normal usage with WIFI at work.

I updated my H815p (south africa) to Marshmallow 6.0 using the LGup utility the first time I flashed I selected update only option, and I was getting unusual drain so I retried and this time opted for refurbish option which I believe is the fresh install option, and still only get 55 min screen on time. Android OS is keeping the device awake all the time. What can I try to solve this.

Factory reset, set it charge overnight, then goes to around 30% with 1 and a half hour screen on time. That's what I was getting previously. I've reverted to Lollipop.

thank you very much sir !
great solution without root !

Since getting the update my battery performance has been terrible. Its takes hours to charge the phone and when left off charge last night i lost almost 20% with thr phone doing nothing. When i use my phone the battery can be seen draining.
I have restarted the phone a number of times. Dont really want to do a hard reset though.
I have emailed LG and shall keep you all posted.

Hi,
I joined this forum just for this issue. I was all excited about the new battery improvement with MM 6.0 although my LG G4 had excellent battery life before - thought better is always a good thing.
Until I upgraded to MM 6.0 about a week ago. I thought I was just using my phone more as it kept being at 20% by 5pm when I was never less than 75% before?
So I started doing some reading and checking the battery usage and installed Greenify.
Last night I had my phone at 100%. Unplugged for 8 hours with no usage - I was asleep...
This morning battery was at 80%???
So I checked what is using the battery. The issue is that you cannot reset these items to zero but they do seem to fluctuate so this maybe a current usage? I pulled the battery for 30 seconds and the percentages are about the same.
Google Services 15% (I suspect my location services that are enabled but they were enabled under LL 5.1 and never killed the battery).
Next is a weird one com.lge.exchange 12% (I assume the exchange server I get work email on) - have always had it before as well if that is it and have not changed the sync settings which are manual so only get mail when I call for it)
Phone idle 12% - what is phone idle taking 12% for?
Cell standby 11%.
So based on a 20% drop over eight hours with ZERO usage other than standby - my LG G4 will last about 30 hours on STANDBY. No usage - just sitting in a quiet room.
Can someone help what is now sucking my battery dry all the time?
TIA
Trevor

I have the same issue, after I did the V20D-JAN update a week ago. My SOT dropped from ~4h to less then one with "Android System" beeing on top of my battery history with 50%. I really wonder, what happened to my device.
I did a total of 5 factory resets, 2 full discharges (not hard, when your battery only lasts about 30min of continuous usage) and still, nothing changed. It even got to the point, where it discharged while on the wall adapter after a factory reset. I installed no apps, no root or nothing. Full stock after a reset and it dropped charge in no time.
Disabling location, logging, LG health and most other stock apps after a factory reset did not change a thing. "Andoid System" was at 40-50% battery usage in less then 15min after I booted the phone.
Anyone else had this, too?

Battery life after update to MM beta?

After I update my Z008 to MM beta, my phone seems to use more battery (10% in 20min with screen on and wifi). What I tried yo do:
-Delete batterystats.bin
-*few days later* Wipe data from recovery
It still consumes battery like above. So I would ask is this normal or I'm having some problems with my battery? Thanks in advance.
Edit: After a full charge, my phone says my battery can last approx. 2 hrs. I leave it over last night with wifi, 3g off consumes ~30%.
I'm using Greenify and Amplify.
Make this new thread + edit consumes 6% (90 -> 84)

Reverse

Don't use Greenify and Amplify, they are useless since now that doze in implemented, i also would check for any wakelocks.

Buddy, this situation is happen to everyone with MM beta rom... just enjoy it and wait for the next beta update.. ?, maybe the next update will be better... 'beta' have a lot of bug & deficiency

Heavy Battery drain from Android System after upgrading to OOS 4.1.0

After upgrading to OOS 4.1.0 over OTA my Android System usage started to drain the battery. So i downloaded the full zip and did a complete clean flash of OOS 4.1.0. Even after that the Android System Usage is draining the battery. I'm attaching the screenshots. Any solutions to this ?

Clear Googleplay services cache and app data, then reboot.
Haven't tried it myself, though i have read it has helped many

Settings / backup and reset ( turn off backup )
Settings / battery , click the three dots at the top and check the power hungry apps and enable aggressive doze and whilst in aggressive doze settings turn on nearly all of the optimised apps just don't optimise things like phone , messenger , WhatsApp if you use them regularly ...
Hope this helps and if it does then please hit that thumbs up button it means the world to me....

are you rooted ?

This is probably not because of Google Play Services.
Can you share screenshot of "Android OS" battery usage as well? I bet it has keep awake time over 1.5hrs.

Snap. I have the same problem here too. Only thing I haven't tried was switching backup off, but I really don't want to live without it, it's just too useful now.

My battery drains even when the phones not in use. I had great battery time at the start (6 months ago) but now it hardly lasts for 20 hours with normal use. Wonder what they did with the OS or maybe its cheap manufacturing

**** OOS... I littery Switched to VertexOS for this reason and I don't see a difference other then Vertex being way more peformant and batfery friendly.

Yeah, happens me every week after a clean install despite all the play services data delete, cache, etc. Always ends up like this. Hopes it gets fixed, Nougat hasn't been going well on our OP3

Me too, heavy draining even when I don't use my phone ?

Did someone already seen this?
