¿Is it normal? Battery drains too fast because of "Android O.S."

dres85 — Tue, 13 Nov 2012 15:45:58 GMT

Hi,

I'm using Android ICS on my Xperia U (Official Iberia 4.0.4 -- 6.1.1.B.1.10 compilation) and I'm having trubbles with the battery behavior because the process "Android Operating Sistem" (Sistema Operativo de Android in spanish).

¿Can someone please help me?

Here is a screenshot, in 3 hours 12% battery drawn in standby mode 95% of time.

yes, there are times when android OS sucks up the battery. 60% is too high.

but in the short time, of 3 hrs nothing can be said for sure.

Use your phone normally till battery drops to around 30% and then post screenshot.

usually it will be around 10-20.

And you can also check running applications and kill everything what you don't need

That screenshot is made with the fresh installation, no other apps installed, just the default ones.

So, it is not because any application installed by me.

Damnit, I can confirm this, my phone only last for 5 hours tops. It's always Android-system which is 76% atm.

Barely any background apps.

Also, most of the time I can't take screenshots.

then you've got a serious problem. Restart your phone immediately, if you haven't done it recently. If it doesn't work, repair you phone with SUS or PCC.

Hi again,

I have a new screenshot after some hours of use, same result:

As you can see, I haven't used my phone for playing, calls or any other thing that use up the battery, 95% of time in stand by mode.

Any help would be appreciated.

Another screenshot of the detail of "Android Operating System", I'm pretty sure is not common having so much CPU time:

Thanks in advance.

I'm sure it isn't normal. My phone acted like this a week ago. Restarted it once, and now getting 2 days backup in stand by mode most of the time.

If the problem persists, do a SOFTWARE REPAIR with PCC or SUS.

I've allready tried to restart my phone, but the problem persists.

I also tried to flash it with the Sony official ROM (4.0.4 Iberia), I did it twice and still having the same battery problem.

So I'm going to repair my phone with PCC, the only thing a haven't tested yet.

Thanks, if someone has other suggestions please tell me.

Did you checked running apps as I mentioned upper? Because those processes are hidden under "Android OS"

Re: ¿Is it normal? Battery drains too fast because of "Android O.S."

dres85 — Wed, 14 Nov 2012 13:16:31 GMT

Yes, I said before:

"That screenshot is made with the fresh installation, no other apps installed, just the default ones.

So, it is not because any application installed by me."

Thanks anyway.

And that's what I say - there is running a lot of useless system/default processes. It depends on it what you are using in phone, but for example on my phone is ruunig only 4-5 processes. I killed everything else and now it looks that I made new personal record regarding battery - appr. 8-9 days (before it was 7-8 days)

No matter wich apps are running if I haven't installed anything, it has no sense if you buy a phone that drains battery so fast because of default processes pre-installed by Sony.

Anyway, I've heard a lot of times that Google doesn't recommends any task killer in Android.

I think it is obvious that the behaviour isn't normal, is it?

Thanks.

No problem.

Going back to the original post, would be nice if someone (from Sony support maybe?) could help me.

Thanks!

I have the same percentage over 50% and my battery last 1 day and a half, 2 days the most (closed during night) with WiFi on all day, bluetooth and some internet checks or calls not very heavy. Still on GB 184 fw. But I have also some apps installed. Don't know if it's normal. What is normal anyway with XU? :smileygrin: There's too much elements involved in a smartphone so I don't think you'll get any specific help other than repair or factory reset.

Do what you think But keep in mind that your ICS is completely the same as mine, and your HW is completely the same as mine So how it's possible that my battery is working 7 days? Because of that what I'm posting all the time in this thread
