Android system always seems to be the top user of battery on my phone, even above screen! The days I have the screen off and the phone just idling I'll use up 20% just from android system and kernel. Any ideas why?

i am using my mobile for 2 months but there was no problem in past but now its making battery problem
Android Os Usage is 25 % and Android System is also 25%
So times Android OS usage will 8-10 percent otherwise 25% all the time
i have tried:
Changing Os Version
Factory Reset ETC ETC
BetterBatteryStats
Install BetterBatteryStats and find out what processes are draining your battery.
Better Battery Stats is the app to use.
For me, it turned out that turning of keyboard sounds etc made a big difference.
was facing the same issues.. for me it turned out to be Google latitude, signed out of it and now its back to normal
Hello All,
I have just noticed a strange phenomenon on my Lumia 920.
If I check the battery level, and then restart the phone, the battery level can change DRAMTICALLY.
An example... earlier the battery was on 52%. I shut the phone down, and restarted it, an suddenly the battery was down to 30%.
I know that the battery can drain fast, but not that fast
Has anyone else noticed this, or is it something on my phone?
Just for information, I am running 8.0.10211.204
The difference may just be lag time between battery status updates.
Atually, reboot the phone does use tremendous amount of battery. It happens to all phones. During boot up, the battery gets a heavy work out and hence the reporting after that tends to be on the low side.
Hello,
I have a problem with battery on my Samsung Galaxy S3. Let me tell You my story.
After buying my brand-new phone the battery life was quite ok, I could be using (games, music, internet) my phone for almost all day and I was charging it every night. After two years of using, I rooted my phone and installed CyanogenMod 11. Then the problem appeared - after some time the screen was flickering and device was turning off. I was really confused, so I changed my rom to another, then another, another etc. Then I saw my battery is swollen. I bought brand new, original battery and used CM12 for maybe one month. I changed cause of battery, about 3-4 hours. Now I'm using Android Revolution ROM which is modified stock ROM, but has improved RAM use etc. Now my battery life is much better, but it can not afford more than few hours without battery saving mode on, or 8-10 hours with battery saving on. Here You can see a screenshot from my phone (I would post this but spam setting don't allow me)...
Is it normal? I thought battery life on my phone was better. I haven't made any battery calibration. Should I try this out (cleaning battery stats)?
Thanks for Your answers.
There is no normal for battery life, a rough guide is 5hrs screen on time from one battery is good. Unless you run battery stats you won't know what the problem is.
It all depends on how you use your phone, I use mine completely differently.
When S3 was my primary phone and I used him extremely hard than battery needed to be charged every day. Now, when I'm using him occasionally battery remains operational even a 5 days.
It is not normal in daily use to charge every couple of hours especially if battery is brand new. Of course there can be power leak on IC chip due to overheating in past but usually apps and wakeloks respond for quicker than normal discharge.
Maybe there is an app in your play store shelf which drains battery juice. Try to flash any firmware you like but do not restore your apps. Try using your phone per one day and check how it goes.
Meanwhile you can install cpu spy to check deep sleep state. Also an app for wakeloks diagnostic, ie gsam or better battery stats.

Okay, I downloaded Wakelock Detector & CPU Spy and going to take a look how my battery is being drained.
I have always had a really poor SOT on this model.
Only once it did 4h, but normally it's about 2h or less.
I don't have many apps and I don't use stuff like facebook or other hungry social apps.
Since some days I started trying to boot into recovery after the battery reaches 0% and the device shuts down.
Well, yesterday it remained turned on into TWRP for 1h43m with screen brightness set at 50%.
I can understand that TWRP doesn't drain battery as a full running MIUI with apps and antennas, but it should be at 0% or anyway almost at a level that could not handle a rom running.
Does anyone have an idea of what could be the problem and how to fix it?
it's about your rom, try another rom and u'll have better SOT
TWRP doens't have many services as google services so it drains less battery
but your problem is the display of your battery, try some apps that calibrate battery
if all can't help, sorry to tell you that you should replace your battery
From the past few days the screen on time that I get has drastically reduced, I easily used to get 8 hours + but now nothing more than 5-6 hours.
The biggest concern is Android system which is draining the battery.
My phone is rooted and runs on radon kernel
