Android System Battery use!!!!

Under battery use it says 87%..is that normal??

In my experience of owning a G1 and an Evo (Both Android Devices) I have never seen the percentage be that high before. I just checked my Evo and my Android System is 27%. Im not sure if any harm in it being that high but it doesn't look normal to me.

i just checked again and it's now 91%

Do you have all of the bells and whistles running? Constant updates via Facebook/Twitter/Flickr/Weather/Gmail/etc? Something's got to be running in the background if Android system is that high up.

Also check you google syncing.
I dont ever use calendar, so disabling it from syncing was a good way to go.

i have all syncing off..i pretty much have everything off to save battery

I just looked at mine...pretty much all the syncing on and live wallpaper...Android System 10%.

Definitely sounds like there is an app keeping the phone awake. Also there is the chance an app could have a memory leak.

I don't like that HTC Function test program that's running. It's the GSD.Apk or something like that in /system/app. Back on the hero this app was a big battery burner. Gotta find a way to get rid of it.

great..i just checked and it's up too 95% now..i have no idea what to do..

Turn the phone off, and turn it back on...that will probably clear up the problem...

The moderator over at android central had this to say
" That means that 91% of the things that have used your battery are part of Android and not third party apps. Not that Android System is running 91% of the time. The higher the number for Android System, the better"
So i guess that explains it since i haven't been using third party apps yet..

How soon after unplugging your phone are you looking at this percentage? This number resets every time you unplug your phone. If you have just unplugged your phone and haven't done much with it than the android system percentage will naturally be high.

No Real Solution but helped me quite a bit
Sooo... I believe i was having the same problem. It was accompanied by an extremely high temperature (processor (140F) and chip (120F) ). ((I scaled the processor down to 600mhz and that only marginally decreased the temperature 5-10*)). I saw someone mention a memory leak... well my widget says that i still have a healthy 383MB of ram available and it seems to be stable at around that same figure. I also noticed that in the status bar the data (up) (down) arrows (underneath the H+) showed a download flash 4x then showed a constant arrow like i was downloading something (down arrow, 2 sec, down arrow, 2 sec, down arrow, 2 sec, down arrow, 2 sec, then a constant arrow down). My Network traffic widget showed that I was downloading at intervals of 1sec at a rate of 1kbs. This continued until my battery died or I turned on the wifi and connected to a network.
My solution that yielded a (checking now) 24% battery drain from Android System (from a previous 70-85%).
I deleted a great few apps (most recent first of course) but the thing that showed the most benefit was to change my gmail password on a computer and dissallow my android to log-in to gmail.
I believe it was/is a syncing error and a bug in the android system itsself.
also facebook has been blamed for increasing Android system battery usage.
I went the extra mile and deleted linked in, facebook, and twitter. as well as deleted my moto-blur accounts. As i said im only down to 24% which is still very high for this process (from my experience).
I hope my trials, findings and long-windedness helps someone and sorry this is such a long post.
I still have no real solution. I'm here looking for answers too!
thanks in advance

SRY android dev probably just fed you some BS
I'm no mod, but when the operating system uses all your resources thats NOT a good operating system.
a smooth running and new android device should use only a small percentage on Android System, like were talking 5% or less. not 90%
that "mod" told you that the operating system was doing all your phone could do without any 3rd party apps.... ERRONIOUS!
Again no disrespect if im wrong (im no DEV)
But durn that sounds fishy

Longer Battery Life!

hi everyone,
i just wanna share my experience with my Samsung Galaxy S.
i have finally managed to keep the phone running with "normal phone usage" for more than 1 day
it is true that the multimedia features usage was to the minimum but still
2 Days, 16 hours and 43 minutes is an excellent number,
and still i have 15% remaining in the battery!!!
Check the screenshots below.
All what i have done is:
1- installed Voodoo lagfix
project-voodoo.org/download
2- installed Advanced Task Manager (ATM)
getandroidstuff.com/advanced-task-manager-android-download-v50/
And make sure to enable the Auto-End Running Apps features in ATM, i have used the 30 minutes frequency.
i am still unable to believe the difference that i got from this combination.
Voodoo has really fixed the lag issue and apps are running so smooth.
and with ATM installed the battery life has reached unbelievable numbers.
the installation for Voodoo was so easy and no complications, i have just used the update.zip file and it was so fast and easy.
check this yourself and tell me what you got from it.
cheers.
EDIT:
i forgot to mention that i am using ADW.Launcher instead of TWLauncher.

That's nice.
My record with light usage was 4.5 days.
In that particular case, I still had 50% after 3 days but made a lot of calls on day 4 so the battery went down quicker.
Key setting is to switch the phone to 2g when not needing 3g and also turn off the internet connection through the mobile provider and only use WIFI where available.

Very nice usage, but do you have push email active?

Congratulations abuatwan but i still think you could get longer from your battery. You say you have Advanced Task Manager running and set to start up every 30 minutes.
That costs power to start that up (as does any app) and when its killed whichever apps/processes its deemed to, if they start back up...well that's even more power lost lol
Android has its own task scheduler/killer built in and really all you are doing is battling your own system.
This will explain in much more detail, even if you don't understand everything mentioned read on and try to take in as much as possible.
http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
I do agree though that with the galaxy, something needs to be done as it does in a way run better with a task killer (not counting the battles and power costs)
I use a free program called Auto Killer Memory Optimizer which tweaks androids built in task killer meaning you use your system as it should be
I've had mine running on 'moderate' preset setting for 2 weeks now and i wouldn't dream of installing any other task killer

The default setting for killing empty_app processes on Galaxy S is 48 MB. The moderate setting on autokiller is 40 MB, so you are actually *decreasing* the memory tolerance, making the memory management worse! I agree with you about the article, but with a strict setting you will see much better performance, try it.

My SGS keep 3 days max with normal use with disable the data connection with GSM and 3G

I do 2 days with browsing and stuff, seems my battery drains less quickly on wifi then it does with 3g or H =\ killing stuff with ATK is pretty handy as some stuff that i never use don't really mater to keep running in the background.

no, during this period i have turned it off, actually i have turned off the Auto-sync option.
i have played some games, used the browser (over Wi-fi) and used GPS but that was very minimal.

great,
if i can just change the default likker setings, i believe that will save lot's of battery
Definitely i will install "Auto Killer Memory Optimizer" and will try both profiles, the moderate and the strict.
Thank you

I do get this with my normal usage, 2 days and some hours - can't remember exactly. I have wifi on constantly, 3g when outside, autosync and push always on, autobrightness, no task managers or lag fixes.. Just stock JM2 :]

I have never managed to get more than a day's usage out of my phone. Today my display has been on for 1h37m and the phone has been off the charger for 5.5 hours, my battery is down to 66%.

good luck, in 3 weeks or so you'll need to do a factory reset because the SGS software/file system is a P.O.S

Ahh well that's new to me, Thank you Tyxerakias. I do wonder what else this app is tweaking then because using Super Manager memory widget i had noticed that i would get slight lag when swiping screens if the reported memory was showing around or below 70mb. The 70mb figure might be wrong as i use a lagfix but the point is that to me around 70mb showing = lag. After installing Auto Killer Memory Optimizer i would sometimes see as low as 50mb but still no lag. I got rid of the memory widget after that as it was just displaying useless info and taking up screen space.
I would be tempted to try the strict setting but my phone honestly flies on moderate and ive also heard if you set it too strict then it can end up killing off things like the clock which means your alarm will then fail.

why 3 weeks? are you referring to the Froyo update? and what is P.O.S?
Personally i wouldn't mind doing a factory reset if you ARE meaning for Froyo as flashing Froyo will reset it anyway...2 resets is no more loss than 1 reset if you are backed up and ready to flash

lol ahh i get it now, he means the file structure in the Galaxy. Samsung chose to use their own rather than a proper linux structure and i've seen many devs also saying how it was a very bad choice.
Well i've had mine for over 2 months now and no loss of data or anything yet so its fingers crossed here lol..........i will be backing important things up as a precaution too
Yes, that app is useful and i am confident you have noticed that

I don't use a task killer, they drain the battery.
I'm pretty sure you would get the same battery usage with screen on vs. screen on and movie playing. Playing a 2h movie drained my battery for 25%, screen on for 2h was about the same so...
I just use Juice Defender ultimate just to be able to select a few features:
- Activate Data/Wifi for 5min every 2h (would be better every 4/6hours but whatever...)
- Data / Wifi off when i sleep
- Leave data/Wifi on when the screen is on
Basically, my phone only syncs / uses data when my screen is on (or every 2h just to push emails if needed)
I noticed that this really really helped me. 3G and screen on really kill your battery

Any tips for a better battery life...?

What settings is everyone using to get the most outta there desires hd battery!?
I know it will take at least 4 cycles to get the best outta the battery, but at the moment I can literally see the battery draining, its not good! I lost 30% within an hour and half! :0(
I'm using advanced task manager, and it never seems to kill all running apps straight away when I hit end all!

1. Dont use task killers...it doesnt work with Froyo and it doesnt help...uninstall it.
2. Empty the battery to the 0% and leave it on charge when phone is off all night.
3. Turn it ON and use it untill it die again...then again turn it off and charge it for 3 hourse. Turn it on...its calibrated
4. Use 2G if you dont need 3G
5. Use max 70% of display light
6. Use only must have online update programs
Thats all...I did that on HD2 and I didnt have any problems for all day...and I used it normaly. In stand by it was 1,5% per hour... with mp3 was 10% in 1hour...etc...
Have fun!

How come task killers don't work? How do I stop apps from running in the background now then without a task killer? Won't this kill the battery more??

No it wont...its like using a notebook... if you have notepad, browser, and solitair opened...but not working with them...they will not use your processor and energy...it will only use your RAM memory... And thats the same with android..BUT after some tome (for example 6hours) if you dont use some app...the phone will automaticlly turn the app off. And in any posiblle way you would never use more than 400MB of 765MB RAM ...so memory is not a problem

My first post here on XDA so hi
Now, I'll just correct you a little. Your example was pretty much correct and a nice one, but Android OS doesn't kill tasks when amount X of time has passed. Android kills tasks when it needs more RAM (=when there are too many processes running), it kills the least used process. Android OS usually runs loads of different processes, the cool thing is that they don't consume any battery because they are not actually used. These processes are stored in the phone's RAM memory, whether there is something stored in the RAM or not, the RAM chip uses the same amount of electricty. Thus processes that exist but are not in any applications' use, don't consume battery. Therefore you don't need a task killer, in fact a task killer reduces your battery life because it kills the processes and then the phone has to restart them, and this cycle continues over and over.

So which is the best way to come out of an app? Back button or the home?

Both are as good, it makes no difference.

I have found that turning auto sync off when not essential saves my battery quite a lot. If I need to check something ill refresh that app. Once I'm near a place I could charge ill switch it back on.
Just a suggestion. Try it and see how it goes for you..

How do i turn off 3G and use 2G network? And how do i turn on 3G when i want to use it?
For some reason after a hard reset everything seems to work fine. Sms messages receiving in time (had installed task killer which i think made the problem possible) and all of a sudden 3G and HSDPA is available. So battery life all of a sudden is less to so how do i change this?

You can go to settings/wireless and network/mobile networks/network mode/gsm only
You can also install extended controls widget wich has a widget wich takes you directly to that screen. A direct switch is not available in this ROM.

Do you have a source esp. regarding this piece?: the cool thing is that they don't consume any battery because they are not actually used.

Circle battery mod
This is still kinda on topic, but I find it's much easier to get a feel for battery life, or what's using it all up, if you have something that actually gives you values all the time. I have a circle battery mod, but a percent meter or widget is just as good. It's nice to have it in your face, instead of either intuition or constantly going into your settings to look up the value.
Just my two cents!

Constant Low Memory [N][all roms]

Hey xda-ers,
I have been plagued by this issue for quite some time and wanted to see if it was just me, or if others share my pain.
Since migrating to Nougat I have found that my phone starts to slow down and freeze after some usage. Typically after leaving some apps open.
The problem immediately goes away once i hit Clear All on the recents, thus I think it is a RAM issue.
In all kernerls or Roms I have tried the problem persists, even if selecting "Aggressive mode" for low memory killer.
I always thought that leaving apps open will not impact ram, as android "understands" theses are not being used (hence why all "ram managers" are just snake oil).
So is anyone else getting this slow down after a few hours of use?
Any tips/tricks to help with this?
TL;DR: how do i fix constant low memory on Nougat roms?

It must be a particular app/set of apps that would be causing this. I see from your signature that you are on Nitrogen OS, as am I. In my particular case, I have never seen more than 1.2GB RAM of the 1.8GB used, the usual average is more in the mid to high 800 Meg range. You could check for yourself in settings, under memory, the current usage is shown. There is a further sub menu in there that shows per app memory used. Check and see if you can identify the culprit.
P.S: I do use Greenify, maybe that keeps the RAM usage low? Maybe someone else can chime in with their usage as well.

Hi, thanks for the reply.
I also use Greenify, and when checking the app usage (which i have monitored for a few months), I see that OS uses around 1.2, and chrome and other apps around 100-200mb each.
However, it seems that the moment I have less than 400mb "free" it starts to glitch.
Also, issue persists even with Tesla Rom (which is what i moved to a few months ago).
Maybe this is just the limit of the N4 with newer apps...

For me the android OS is currently around the 350MB mark. Tap on Android OS and see what is using the memory. Maybe the cache is running high for you?

Multitasking/RAM

You're busy and don't have time to wait, which is why you need to stop reading this thread and get back to organizing your Pogs. Rate this thread to express how the Xiaomi Mi A2 Lite performs when multitasking. A higher rating indicates that the Xiaomi Mi A2 Lite keeps many apps in memory so that they don't need to reload, and that when moving between apps, transitions are smooth and performance is excellent.
Then, drop a comment if you have anything to add!

I noticed recently that I have very few apps open in recents. It seems to me like the phone is killing apps prematurely. Thankfully, app launch times are not that bad, so even with reloading it is not terrible.

Hello, I'm creating an account in order to give my real-life review of this phone. The previous phones I had were HTC One M8, LG G6.
Ram management in this phone is not the best in the world. I am not the kind of guy to tap of “clear all apps” all of the time. But if you keep an app open in the background and let it sit of half a day, it will have to reload.
While I pretty much never exceeds 3.5GB of ram usage, I wish apps could be kept open without reloading.

i have 4gb of ram its very smooth phone

I changed LMK profil in Kernel Auditor to Light and turned off adaptive LMK and changed to 0mb for foreground and visible applications and I can use full ram whitout app reloading, but the phone is still smooth and fast and stable.

I have a problem with multitasking.... Processes of all apps turns off right after leaving them. Tried everything, went through all battery settings, developer's settings and such. Tried every option. Multitasking is simply impossible on Mi A2 Lite (Pie 9.0). Apps turns off instantly after I leave them. Optimization for each app is turned off, Adaptable battery turned off, Battery saver turned off, also. Nothing helps; So sad, and it seems there is no solution for this.
EDIT:
It works, phone needs restart in order for settings to be applied.

So far no problems encountered in multi-tasking, on Android 9. Not rooted.

Has anybody found any fixes for this?

It is terrible.
I use the original ram and if I copy text paste it to other app then go back to copy another when I go to paste it's already lost the first before the reload.
For example I copy a bank account number, paste it go back and copy the name and after gone. Because of reload the account number disappears.
And this is just one example how annoying it is

It is pretty bad. Although, I feel that it had been better before certain security updates, but I couldn't remember specifically which ones. Right now, at August update, I've got all optimisations turned off, battery saver turned off, adaptive battery turned off, individual app optimisations are also turned off, in developer settings I've got standard limit of background processes, killing apps is turned off.. I really don't know what else one could turn off, in order to render multitasking operable. I'm on stock with unlocked bootloader. Any help would be massively appreciated, because I am really frustrated by having two out of four gigabytes of RAM which is always free and unused, but my apps are getting killed almost instantly after I've left them.

My multitasking is better since I have disabled Adaptive Battery.

Well, it should be, because, what this option does - it basically either kills all apps (if on) or lets them all work in background literally all the time (if off). That's why it's not really a good idea to keep it off because it will absolutely destroy your battery life.
I haven't updated since the October update and am not planning to - it is the last update that actually works properly regarding multitasking. All my optimisations are turned on and I reboot my phone every time after I've charged its battery - for some odd reason the multitasking works flawlessly after this.

Yes, if I do this even in November update, my multitasking is good. When I keep the phone on for a couple of days, it deteriorates. For a 3Gb phone, it makes no sense to have bad multitasking... Poor Android development I guess.

Thats what i am talking about on my Ram Leak thread. Thank you for your comment.

Multi-tasking used to be waaaaay better in Android 8.1, but with Pie update it's worsened. I remember being amazed by how many apps could be held open in the background back then. I have the 4/64 version.

I have the 4GB version and I do not really do multitasking (multiple open windows), just share to Telegram and copy-paste between applications. It is anything but snappy; sometimes it takes looong. It does not feel like 4GB memory.
