Ever since I have bought sony experia ray i have felt the battery is pretty weak. My old phone was not a smartphone and it lasted me 1-2 weeks before having to recharge it. I realize that smartphones last like 1-2 days but my battery is just nuts. First of all, it often notifies me that battery is being drained and a red icon appears. I am now charging it and even now the red icon is there! Also when I play games, i lose 10% every half hour, is that normal? How do you get rid of the red icon? I have tried to stop most apps running that i dont need and it still happens, help please.
