[建議] SE W910i - battery problem

Dear all,

I bought a W910i from 3 last month  and found that charged full battery for just using 2.5 days.  I was not using it for walkman and playing game.  Only normal use, one day talked about 25min.

But manu said that the W910i can be used for 350 hours for standby and 210 mins for talking time.   Why?   


I tested it again

Performance:-
Now can use 3 days for standby (about 72 hours)
and about 120 minutes talking time only all together, did not use for listening and playing game.

All W910i user,  is it OK?
