Model No.: SK17i

Android Version: 4.0.4

Battery draining @ drastic rate ever since I started using the great Xperia mini pro. Hardly a backup of 13 hours.
Even tried to turn off 'accounts & sync' but no help.

Hi there. This has nothing to do with accounts sync I think. I hade the same problem. This problem occur sometimes and the fix is easy. When you notice that the battery is draining fast and Android os is the cause, just shutdown your phone and power it on again.

Problem solved. It happens sometimes but not very often. Maybe its some kind of bug in ICS, because I did not had this kind of issue in GB. In 587 build it has not happen till now.

its an easy fix, but don't know why it is happening. I think that some process hangs ....

No help for me even after updating the build to 587.

The battery is draining without even using the phone for a single call...

Quite sure that the phone will shut down due to low battery within next 90 minutes...

I also have this problem, and while the shutdown/restart process does seem to be effective, I have also found that certain apps seem to make the problem worse - and more persistent.

The app I identified as causing the problem to get worse seemed to do the damage even if it wasn't running. And I did believe at one point that even after uninstalling it the problem continued, meaning that a reinstall of the OS was needed to get back to more normal battery usage. I can't now quite believe this can be necessary, but it might be worth a try.

I suggest you consider uninstalling all the apps you have downloaded, and see if the absence of apps makes the Android OS problem improve. If it does, re-install the apps one at a time, keeping an eye on battery usage.

It has to be said that, even without Android OS eating the battery alive, battery life is rather disappointing.

This seems normal to me. When i first got the mini pro it was about 12 hours a day with full usage.

After ICS update I get about 14 hours a day usage.

I would also be happy if my phone gives this backup with "full usage" but this xperia mini pro is giving the above quoted backup "without any usage".
Accounts & sync - Turned Off
No calls entertained, sent No messages.
The phone is simply on a stanby mode.

For how long have you been running on .587?

It usually takes 5-7 days for the Android system to configure and settle the battery usage to an optimized level.

I updated my xperia on 28th Sep, but it hardly helped...

So, I finally re-installed the OS with updates from Update Service by Sony, two days back.

Now, after the fresh installation the performance has improved but will be still oberseving xperia for the next two days and post the result.

The latest update (.587) really worked well for me. Performance improved and optimized

Usage: about 15 calls answered, sent few messages, accounts sync working fine, played a game & searched for new apps at Play Store using Wifi
