New iPhone 4s, 64Gb, black, unlocked but on O2 PAYG (in UK)
S/No. starts C39GK3B2, iOS5
Collected my very first iPhone last Saturday 12-Nov-2011 with iOS 5 pre-installed.
Brand-new micro-SIM from O2 shop in Meadowhall.
Initial battery drain whilst using the device horrified me. Not quite seeing the percentage drop minute by minute, but drops 4% in 15 mins or so.
After getting to under 20%, I fully charged the phone over a few hours, then turned everything off to see what standby time was. Initially very encouraging (for an iPhone). Looking like 150+ hours standby with everything turned off.
After looking on this forum, decided NOT to apply iOS update to 5.0.1.
All email/data/apps downloaded via home WiFi network.
Settings:
Bluetooth OFF
POP email OFF
iCloud OFF (not activated)
Notifications OFF
Location Services OFF
Siri ON, Siri w/lift OFF
NO Exchange email
NO apps running (that I can tell)
Brightness approx 50% - auto OFF
Auto time-zone OFF
3G Data OFF
3-4 bars 3G cell 98% of the time (no cell hunting)
2-3 bars WiFi 98% of the time (no wifi hunting)
Usage statistics are:
Usage 11h 36m (don't understand this as it hasn't had this much use??)
Standby 4days 17h
After getting to 20% I did some YouTube etc to finish off the battery and it dropped some 3-4% in 15 mins as reported above. Let the battery drain all the way down 'till phone shut off and followed this by a slow charge via USB over 3hr 25min and a reset/set-up as new phone.
Will add an update to this thread after I have seen if reset/set-up as new phone makes any difference to plummeting battery life whilst in use.
100% charge as I post this 4:10pm Saturday 19th November 2011. Let's see what happens now.
Cheers
