Well, I own Xperia S from more than an year now. Earlier my phone went dead but as it was under warranty I got my "board" replaced in July, 2013. After I received the phone, I noticed it has been upgraded to Jelly Bean. From last few weeks, I am noticing highly unpredictable battery consumption pattern. It shows 100% at sometimes and within a minute charge vapours to 1%. When charging it shoots from 1% to 100% in an minute. I repaired the phone using PC Companion successfully, but of no use. As my phone is out-of-warranty now, I cannot even take it to Customer Care.
As you guys had this problem before, please help me know how you got this problem fixed. Thanks in advance.
