Neo Battery Problem after installing ICS 4.04

[#1]

Hi all,

I installed the ICS update 2 weeks ago, and since then, the battery don't last even a day! Today, I found my phone didn't chaged to full (it was %87), even it was on the charge all night, and was etremely hot. When I came to work, the charge was dropped to %15 in 45 minutes and it was a heat source like it was going to explode. I removed the battery immediately.

I guess the reason was the update, now the phone uses CPU all the time. Do you have any fixes for this bug?

As a matter of fact, I discovered Facebook in Xperia sync may cause this battery and cpu usage with the help of another thread in discussions. Facebook calendar sync used 311 mb of data since 31th of July!

On the basis that the handset never reaches the full 100% charge I would suggest performing a repair to the handsets software to help resolve any issues you have. I have supplied a link below that will allow you to download the PC Companion.
