Problem on battery life

[Menandro]

Hi,

I read in one article that one of the cons of updating xperia minipro from GB to ICS is that the unit will consume more battery power.

I opened a pdf file and kept it opened for a minute or two, my battery went down from approximate 70% to 40%.

I was surprised when I saw this huge drop on battery life for just a couple of minutes.  Is there any help to improve the battery performance?

Thanks in advance

You can also remove the battery and put it back again.
