I have been using Sony Xperia go for more than an year. I've already updated it to Jellybean(4.1.2). My battery life was used to be a day or so on normal usage. But now its reduced to 2-3hrs max. When the battery is charged to around 80% it shows 100% and when I disconnect the phone from charging and restart the phone, it shows 80%. Battery drain is too fast.I always force stop the apps which are not required, keep Wi-Fi switched off and use 2G internet. When I check the battery usage AndroidOS and Android system are eating around 30 to 40% of the battery, sometimes more than the battery used by screen.
Similarly when the battery level is 30% or so, phone experiences a sudden death and turns off showing battery level is 0%. And when I turn on the phone,it shows correct battery level around 30%.Then battery level reduces like a countdown timer.
I tried to repair the phone using PC companion and in the end of preparing stage,I'm getting an error message showing "Cannot connect to Sony server (error 10)". I can't recognize whether its battery problem or software problem.Looking for the solution to this problem. Please help.Thank you.
