Hey guys, I had a white 16gb 4s delivered on the 30th December and im not too sure about the battery.. Im wondering if I should return it for another new handset as im still in my 14 day period. I have tried all the battery saving settings, and have most things turned off. What I do have on however is gmail setup as a exchange server. I reset all settings last night and setup as a new phone Anyway, I've ran the battery dead last night until the phone shut off by itself. for the last hour of my usage I had the phone playing a video. I did notice that from the battery showing 1% it took about 30 minutes to shut off. Anyway, here's my usage. This is actually straight after the power died and was plugged in and recharging. so, after a battery calibration last night, I took my phone off charge at 6.20 am and its currently at the following. 92% battery remaining Usage 30 Minutes Standby 2 hours Wifi is on, I've briefly read a few emails and the screen is at about 30% So im wondering if I should return it to apple or not?
