Data causing High Android OS Usage

Hi, i am suffering from massive battery drain on my gnex, i have noticed that android os uses approx 50% of my battery, which almost making my phone unusable. I have noticed today that when i switch my data off, i dont lose any battery life compared to when i leave it on and the percentage for android os reduces significantly. i am currently using franco's kernal and before that leankernal and suffered the same issue on both, i have also tried opening the camera after reboot which someone suggested but it doesnt work for me, does anyone else have the same issue and is there a fix to the issue as i would like to have data on.
Thank you

Also check data usage and disable background data of app that continues to update. This will also extend battery life.

I have checked the data usage and Android OS is using 775KB of data, so when data is on it must be keeping it awake which uses more battery

using juicedefender may help you it has very good radio controls that will turn off or on your wifi and data connections depending if you device is on or in sleep mode.
Also for your battery is the OS just showing 50% of the battery usage in the bat stats section ? If so that is NOT 50% of your battery that it has used. that simply means that of the percentage of USED battery the OS has used 50% of that. if your battery is at 50% and your OS in bat stats says 50% it has actually used only 25% of your actual battery.
OS is normally near the top of the bat stat list alongside the screen. unless you are playing games.
its normal

Yesterday i let my gnex battery die and android os almost used 50% with 3% battery remaining, understand where you are coming from, but i have explored the issue further and battery drain is significantly higher when connected to 3g, i will upload a screen shot soon to demonstrate the issue

I faced the same problem, issue was somewhat with auto backup of data, sync of app data & people details in google account,
BUT the main culprit in my case was uTorrent application.
Even though there was no torrent added to it, i didn't even opened it,
it was using 1GB data daily on WiFi and in data usage it was coming under Android OS usage. I uninstalled it, everything went back to normal.
So try to look for such apps which eat up your data in background, it may not be an error of android OS as such.
Hope this helps, Press THANKS if it did help you
Enjoy

Cyanogenmod 10.1 terrible battery life

I have recently installed cyanogenmod 10.1 onto my galaxy s3. The battery life since then has been very poor. If I leave my phone on without even using it, it drains about 1% every couple of minutes. When I look at the battery it says that the process of "phone" is taking up a huge amount of battery. Can anyone tell me why this is or how I can fix it?

Generally these issues are user related and not ROM related.
I was so frustrated with some of the ROMs when I first started out but then realized I was doing a few things wrong (mainly because these ROMs, including CM10 have very decent battery life).
First, I would recommend a clean reflash:
factory wipe / reset
wipe cache (some say twice)
wipe dalvik cache
install ROM
after rom loads, wait 5 minutes (don't touch at all) then reboot
now you must wait.. sometimes it takes 24 hrs or so for a ROM to correctly load.
Not sure how true it is, but some say to now drain battery down, then fully charge.
At any rate, I follow these steps all the time and works great!
Also, keep in mind that most of battery issues are user related.. so think about what settings, apps and kernels are being used on your end before question a ROM. This is why waiting 24 hours or so before installing all of our "crap" will give give the ROM more time to settle.
Hope this help!!!! Happy Flashing

Thanks for the reply. However, I have looked at what apps and processes are draining my battery. And it appears it is the "phone" process that is doing this.

Just to piggyback on spenny88's reply, exactly what did you come from (stock?) and how did you wipe and flash?
This is all key as to how well your device will perform.

I have noticed something similar. I am coming from stock. I am going to guess my battery life is in the neighborhood of 10% less. I wiped everything before I installed CM. That said, this feels so much faster than stock.

Having the same issue with my Samsung Galaxy Tab P1000 (p1 in Cyanogenmod). "Cell Standby" is taking as much juice as "Screen", and I am using Wifi only. I don't even have a sim card in the device. Wish there was a way to disable Mobile Networks without disabling Wifi via Airplane Mode.
I installed through Rom Manager as upgrade from CyanogenMod 9.1 with wipe. I will try the recommendations above and report back.

Try the latest nightly (or RC4) of CM10.1. The battery life has definitely improved a bit.

Samsung Galaxy s3 intl battery drain cm10.1
I recently installed cm10.1 nightly on my international S3, it has cut the battery life down drastically and seems to drain over 10% an hour, even when not being used.
I've tried everything that i've came across by searching and still haven't had any real gain on battery life. Doing a full wipe and reinstalling doesn't help, and i've given it time for battery to calibrate; no difference. Even with wi-fi and location services off i'm getting a big drain. I've even tried switching to Slim Bean, if anything the battery was worse still.
Firstly i'm getting that Android OS is eating up a large chunk (usually above 60%) and using BetteryBatteryStats i don't see anything out of the ordinary in terms of partial and/or kernel wakelocks. I really don't wanna have to put the stock Touchwiz rom back on but that seems like the ways it's going. Any help would be greatly appreciated. Is there anything else i can try?

i find i get terrrible battery life on AOSP when i restore google through the setup. i skip thru the installation and open the play store to enter my gmail. then, before restoring my apps, i let it charge to 100%. honestly AOSP still doesnt have decent battery life, but it does improve if you play with it and try different things

I would respectfully disagree with you. I have run a number of ASOP based ROMs and find them better than stock in terms of battery life. Certainly better in terms of not making my eye bleed (as I hate touchwiz, but that is a personal preference). I find that SlimBean gets me the best battery life of the CM based ROMs.
To clarify, I get just over 1%/hour battery drain, when idle (as measured by BBS) with GPS and google sync enabled, mostly on LTE. My phone happily spends almost all the time I am not actively using it in deep sleep.
The recipe to achieve this is to disable google location reporting and history, avoid tons of widgets that constantly update themselves, disable samsung services that you do not use, and monitor battery usage to look out for rogue apps that do stupid thengs, like hold wakelocks when they should be idle. Dropping the minimum frequency to 192 MHz, and going to ASSWAX (CPU scheduler) and ROW (I/O scheduler) also helps.
To get decent performance you do need to install things properly. Which means ensuring that you don't have conflicting settings or random leftovers. I tend to dirty flash updates but you reallly do get better and more consistent performance going through the pain of a complete clean install (format system, clear cache, reload apps from the store) when you are switching ROMs. Only use TiBu to restore app data. Once you do this, in my experience rogue wakelocks are the biggest cause of lousy bettery perfromance, and you can track down and eliminate these. I have around 150 apps loaded and do not run any task manager/autokiller. My phone typically runs without any reboots or power cycles between ROM updates which equates to rebooting every couple of weeks to a month. I have seen over 2 months of uptime.
Certainly should be able to go 16-20 hours between charges which I would consider real world all day functionality. I guess my point is that rock solid stability and all day battery life is possible if you are systematic about how you do things.

Kernel (Android OS) battery usage very high

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.

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.

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.

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 / 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 ?

Question High battery consumption on idle

My phone is usually on idle and not used due to my job. But Im noticing extreme battery consumption even when Im not using it. Never had this issue with other phones. Last night I checked the batter before sleep and it was at 67% at 1 AM, today its 62% at 7 AM so there must be an issue because it should only drain 1 or 2 percents during idle.
In battery settings the top app using the battery is phone idle.
Im on xiaomi.eu 12.5.6 rom but I had the same issue with stop 12.5.3 so I dont think it's because of rom.
I had great battery life with my last phone which was poco x3 nfc with the same settings and apps so it's not because of any third party apps either.
Anyone else experiencing the same problem?

With AOSP ROMs, I even had worst experience when I installed one of the custom kernels because they somehow didn't put the phone into deep doze correctly. But yeah, the idle consumption is quite high - even on stock Kernel.
Currently I use HavocOS and its stock Kernel - and SuperFreeze (from F-Droid store) to freeze most apps right after screen lock. Idle consumption has dropped to 0.1-0.2%/h as a result. I made a thread some days ago regarding this topic... see here.

Thanks. Im gonna try your guide but it's not the most noob friendly guide I've seen
Just Kidding, thanks for your time.

Oh, my thread wasn't meant to be a guide... I did put it in "Question" like you did, but a mod seems to have moved the thread to "General"
My "solution" is only temporary - at least I hope there are still developers out there who value a low idle drain more than fast charging and benchmark numbers...

Sorry for the OT, could it be that the app. is called SuperFreezZ?
Have you noticed any good battery life gains with this app.?

Yeah, sorry, SuperFreezZ: https://f-droid.org/en/packages/superfreeze.tool.android/
For several months I had the problem that from a certain moment, the consumption at idle suddenly increased enormously (from 0.1-0.2 % to 2-3% per hour). Even if I manually forced all apps to stop, In Android's battery info "Android OS" and "Android System" showed up with double-digit percentages. I could only get the phone back to its previous behavior with a restart.
To date, however, it is not clear to me what triggered this. I suspected GCam for a while, then Osmand+, but I couldn't ever confirm that because the problem didn't start whenever I used those programs, just sometimes.
I never found a real solution for this, but SuperFreezZ did.

The best thing I've used for years now is Greenify, its hasn't received an update in more than a year but still works perfectly

Do we need root to use these apps? I remember using greenify before onmy older devices with root but havent used it for a while. Gonna see how much it drops tonight and then try to tweek some things and recheck it tomorrow night.
Weird thing is, I was getting an awesome battery life out of poco x3 nfc, could it be because of the cpu idle? Because that's the only thing that seems different between the 2 devices. (X3 even had an lcd which is supposedly less battery friendly)

Unfortunately, hardly anyone notices this because most users do exactly what the F3 was designed for: Playing games.
I came from a 2.5 years old F1 and it lasts easily longer than the F3 although it has a smaller battery and a LCD screen... The F3 behaves anything but fully developed. These latest high-end SOCs (870, 888) are really powerful, but unfortunately not equally power-efficient. That's the reason why I throttled the CPU and undervolted the GPU. This dropped the active drain from ~8 %/h to <5 %/h on my device and my usecases.

Yeah. I used to underclock the cpu on my old phones but I dont know about undervolting. wouldnt it cause issues? I just used 3c toolbox app to set a lower max clock and a lower min clock for cpu cores.

Konabess doesn't need root, afaik. Extract the boot.img of your ROM and copy it into a folder of your device. Then use Konabess to modify the settings and repack it into a modified boot.img. This file you can flash with TWRP. No guarantee that it works for xiaomi.eu, but it works for AOSP (at least it worked for me).

I'm ont he same rom as you and let me explain my experience.
My battery has been insanely good. Even with heavy usage over a period of 4 hours, which included 1.5hrs of SoT and pandora playing though bluetooth all 4 of those hours with dolby and viper enabled. Was at 100 and dropped down to 94%. So It may be an app or setting that you have installed causing problems and draining battery. The only battery saver addition I have installed is Universal GMS doze. Idle time for me It takes me about 5 hours to drop down 1%.

Well if there is an app that is causing this, it should be shown in the battery settings. But the only thing that is eating up my battery is phone idle. So it might be a service or something. Im out of options right now unless I find a way to root this rom without facing new problems.... Worst thing with miui is that you cant do things like rooting as easy as other roms.
Btw, would you please tell me the settings and xiaomi.eu version you are on? Im on 12.5.6 stable and using 120hz + vivid color scheme and most of my apps are on blcok background activity except my messaging app. And Im losing battery on phone idle not the screen on time!
Ss below.(dropped from 92 to 82 woh only 30mins screen on time doing nothing but checking xda!) And 7hrs of those 9hrs I was asleep and the phone was on airplane mode + gps off!

You could try BBS or similar apps. Maybe it's an app which prevents the phone to go to deep doze (wakelocks).
BTW: MIUI sucks

I switch my screen refresh rate down to 60hz but since your phone is idle it really shouldn't come into play unless you have always on display or turn screen on for notifications.
Rooting this phone is amazingly easy. Takes like 5mins if that. My Mi 9 lite took longer to root then this phone.
As far as an app draining battery, It more then likely not it since you saying phone idle, which in the past people have said if you phone has problems with signal this can drain a battery. For me this has been a major issue. With AT&T service I would loose double the amount of battery over night (I play pandora through out the night when sleeping). Also if you have apps that are heavy internet usage (unsure where you at but things like facebook and messenger drain tons and yet don't register battery drain on most analytics. And since you using a xiaomi.eu rom I know alot of those bg services are disabled or removed.

Yeah thanks for the info. I used to root my devices easily by flashing magisk but it seems they have changed the method, though I found the method on a post on xiaomi.eu website and rooted my device.
Tried to lower cpu frequencies a little and use superfreez app. It seems better now but not as good as what you say...
Gonna play with settings a little bit more and wait for another xiaomi.eu stable update to see if it's a bug on this version.

Someone made a auto script for it, but you will have to reflash rom and factory reset data. You really shouldn't have to change cpu feqs. Also uploading a screenshot of my last 2 hours. I know its only 21min of SoT but also 2 hours off charger but playing pandora as well as some other app usage but still at 100%

As long you don't push too hard with undervolting, it works quite well. See attached image (it's not mine, but I have oriented to it).
I've never heard of it... This seems to be a powerful tool! Nice!
Konabess doesn't need root, afaik. Extract the boot.img of your ROM and copy it into a folder of your device. Then use Konabess to modify the settings and repack it into a modified boot.img. This file you can flash with TWRP. No guarantee that it works for xiaomi.eu, but it works for AOSP (at least it worked for me).

Konabess without root won't start, any idea?
thanks

Ah, ok... I thought you could load a separate boot.img - my fault, sorry!
Then you've to have root for Konabess...

Just to show what's possible with HavocOS 4.9 and 12.5.6 EEA firmware, see atached screenshot... It's with the stock kernel of HavocOS, but with the modifications I did mention here.
Running for almost 2 days
~8 hrs SOT (2 hrs of which with 120 Hz and 2 hrs of which with 100 % brightness, otherwise 60 Hz and brightness between 25 and 50 %) and still 50 % battery left.
