Whats up guys.. I have a one x and my battery just drains when i go to sleep... Around 20-23 percent.. Even with power saver on and all toggles off.. I tried many apps just to prevent this and still its the same result.. I heard about this app and i just want to share it to you.. Battery drain is down to 4-5 percent within a 10 hour period.. Thats just great!!! App is called Greenify and it hibernates your apps than drains battery.. Have a try and let me know.. Support the dev as well.. Cheerios!

Been using this for a while and it works well. Just understand what your 'greenifying' so you don't think apps are broken as a result.

Does your battery drain even with screen off at night too bro?
Thanks for sharing, this is sort of stuff I looking for
Anyway, I prefer to solve the problem without this kinda application first, I'll try it once I'm at dead end

Not hugely like yours but I use it among other things to get a good full day use out of my phone without limping towards end of the day.
I would use gsam to identify the app drain at night and greenify to help if you can't stop it with the app settings or a fresh install.

I used wake lock and saw google maps draining so much of my battery and I disabled it and so far 4 days battery is good... I mean it doesn't drain. Hope it works.
I use this Greenify with Deep Sleep battery saver at night, Wifi drains alot of unnecessary power in the night, deep sleep turns on wifi and sync every X hours. Managed to get 1 day and 11 hours with total of 3 hours screen time(i use my phone as a PDA not as a high performance device)
Hey Zenfoners
Happy with my phone but I have a problem with battery usage.
I'm using GSam Battery Monitor and Kernel (Android OS) under App Usage seems very high.
For example today the phone has used 26% in 5h 45m with 30 minutes of screen on time. Screen usage shows 18%
But App Usage is 56% and 48% of this is Kernel (Android OS). CPU usage for Kernel (Android OS) is 4h 10m. And the phone has only been on for 5h45m.
I can't check what is keeping wake lock because I don't have root.
On idle using wifi it is using 2-3% per hour when my LG G3 and Note 3 use about 1.5% per hour on idle.
Anyone else have this problem?
I'm glad I found your post. Highly frustrating with my zenfone 2. Massive battery drain with google apps and Android OS. Yesterday or it was Google Backup Transport, today it's some other google stuff. Would love to know how to properly debug this stuff. I tried disabling most of pre-loaded Asus stuff but who knows what's causing battery drain. I can lose over 1% of battery PER MINUTE.
I just did a factory reset and added these apps:
GSAM Battery
Dolphin browser
LINE Messenger
Touchpad keyboard
Google Inbox
Google Translate
Google Keep
Android OS is still being crazy. Amazing that you can buy a brand new phone and it fails almost out of the box, and it seems the OS developer is at fault. No wonder people are switching to iPhone!

So I installed a system update adorable through the menu which seems to be helping now. Android OS still seems the biggest battery drain but at least the drain isn't outrageous like it was before. There's a discussion about the fix on reddit about it:

Were you rooted before? For the 1st "Battery Used by App" screenshot?
I've not been rooted so on the latest s/w update. Haven't seen behaviour like this on any of my recent devices. Terrible battery usage when idle, and all my Google settings (location, backup, etc) are the same.
Well i almost get at 100% of battery status of battery life almost 3 days.
Firmware : 2.15.40.13 Pre-rooted system.img by Shakalaca
Xposed module for ZF2 installed + Greenify (Donate) app
Basically i geenifed all system apps {some you cant greenify) including power saver app which is build in + normall apps.
I will add SS when i will charge battery to 100%.
I cant understand why people gettin device discharging after 6 hours etc.
Follow my guide : http://forum.xda-developers.com/zenfone2/help/how-to-upgrade-cn-version-to-ww-t3101556 to update to the latest WW OTA
Xposed : Here
I'm on the latest WW firmware but I shouldn't have to root, greenify etc. Didn't do it on my Note 3/HTC One/LG G3. What's the point in having 4GB of RAM if you're flushing it every few minutes. I do have location settings and history on, as they were with previous phones, but everything else is very conservative. Zenfone 2 is the only one that shows crazy Android OS usage with same apps and same sync/backup/location etc settings. All on Android 5.0 too!

How you can compare different phones according to the battery life if they were made in different technology and they using Snapdragons not Intel components.
Thats wrong mate
If you moaning about battery life in ZF2 you should compare it with diff zenfones ( ZF5,ZF6 etc.) or other Intel based devices
Note 3 was an Exynos.
So Intel = still bad then
I haven't rooted or anything. Battery life is now acceptable but Android OS is still near the top, but nothing crazy like it was before the system update. Does your build number match mine? I have the TW phone, so I assume TW software.
Battery graph shows almost continuous usage with screen almost always on.

Same build number except for ASUS_Z00A (1.8 ghz 4gb RAM) model.
Well ROOT + XPOSED + GREENIFY = 8 Days show battery )
From 23:00 at previous day i left phone with turned on WiFi . Overnight for 9h it drained 4% of the battery so chart is correct.
I fix my battery drain in this way:
Install all OTA updates
Factory Reset.
Reinstall All.
Battery drain seems to be only if you install an OTA without Factory Reset and with all apps already installed.
It take several hours to reinstall all ... but it works !
No more battery drain here !
I done a wipe cache instead of factory reset. You reckon it's the same thing or would I get better results v so th reset? Currently getting 5-6 hours sot with 2.3ghz 4g2g ram. Thanks

I did factory reset, install OTA update, and reinstall all. Had one good day. Today, I've lost 6% in about 30 minutes. Even more amusing, the biggest consumer is Wi-Fi ... Which isn't even turned on! Crazy stuff.
I think this'll be the 4th time re-installing stuff now. Good times!

Hey there all. If you're still having high android os usage it could be due to calendar storage constantly waking up your phone, check out my post in another thread -> http://forum.xda-developers.com/showpost.php?p=62730039&postcount=21
it is still lolippop 5.0???
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,.
¿GJ?
Did you forget the thread you made 2 weeks ago.
http://forum.xda-developers.com/galaxy-tab-s/help/sm-t800-barry-drain-t3157867
John.
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 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.

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.

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 / apps / Google play services / manage data ( clear data )
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?
Huge wake-up alarm from Android with job.delay and job.deadline :s
I recently purchased a P2. Every thing's good. Battery life is also better than most of the phones. But, one thing that I noticed is that Cpu usage is high in idle state too. I did a factory reset. But, the problem persists. I usually get around 8hrs SOT. I think that's lower than most P2's.
Is there a way to solve this? My bootloader is not yet unlocked. Have to wait 12 more days.
Thanks.
Wait 12 more days, unlock the bootloader and flash the DrainFix.zip that can be found in Lineage and RR threads.

Are you still on Marshmallow ? There was a bug that caused the cpu to stay at 1689mhz on some phones .
And Drainfix wont make any difference . It changes the governor from performance to interactive , but your already on the interactive governor .

I am now on nougat. But same problem. Already performed factory reset a couple of times. Cpu doesn't stay on 1689mhz. Now it fluctuates. But, still heavy usage from CPU.
Battery drains by 7-8% overnight.
I already installed Nougat, but the phone is sleeping as dead. Charged it to 95% last night, put it on airplain mode and today in the morning after 9h to battery is still 95%.
The android battery stats show that CPU is awake all time, but BetterBatteryStats shows that everything is fine.

Here is how it was for me.
I took phone out of the box with MM preinstalled and right after i turned up the screen and connected to my wifi network it asked me to update OS to Nougat 7.0 so i did. The bug that caused CPU stays at 1.69Ghz occures for 100% on Nougat, and you say on MM too ?
Anyways, for me, hard reset solved the problem, at least this one.
But battery drain still takes place. In normal mode 3-4%, in ultra power saving - 5-6% over night (5-7h). This is pretty a lot i would say.
ps: Phone goes into deep sleep mode according to BetterBatStats.
On p2 i get average SOT of around 13hrs

Systemless root under Nougat with magisk:
1. Format data partition to ext4.
2. Type in the recovery terminal :
echo "SYSTEMLESS=true" >> /data/.supersu
3. Flash the magisk12.zip
4. Reboot
5. Install Magisk manager
If you have another su like phh, will not work, you need reinstall the original boot image.
Should be around 0.2%/hr...

The only way to know the standby drain is normal or not, try install GSam Battery Monitor app...
As shown above, native stock ROM S233 should drain around 0.2% per hour, which in turn to be 0.2% x 8 hours sleep = 1.6% or 1.6% of 5,100mAh is 81.6mAh energy consumption...
Conclusion:
P2a42 can survive in airplane mode for 20 days on a single charge.

So, i just checked my Gsam, and here is what is says:
0.7%/h drain in standby which is more or less what im losing of battery juice over night. It's stick Nougat form OTA update.
Right now im at 44% and i switched into ultra power saving mode. It says that i have left around 51h. I dont think this is normal. Isnt it really very little time ?
It's just a little over 2 full days @ 44%
Damn...
Should i return this piece to store with complain i got faulty one ?
Can you please switch to ultra power saving mode just for a second and tell me what did it calculate aproximately as time left on battery ?
