Prolly an app running in the background causing it. O be safe. Kill all apps before going to bed.

No bro...i turned off all the apps b4 goin bed... my fren who used 3gs also say that once in a blue moon encounter this prob also...

so, jz wanna ask ppl here using iphone4 whtr they experience this...

Bro,what you mean by background apps?if alarm?

I always turn off and on my phone once this happens. suspect some of the apps is giving this problem.

I also encounter this recently on my iPhone4.
Fully charge at night. All background apps has been closed manually, except I had set a repeated alarm.
(had closed all 3G, EDGE, location service, notification. Usage = 9 minutes, Standby = 9 hours)
When wake up in morning, it drop until 82%.

Usually, when I fully charged, and when wake up, it will drop until 98%. Not so drastically until recently

Wondering whether can send to machine store to diagnostic the battery health

EpiCenter is authorize apple reseller .. so it could be approved by apple all product sold by epiCenter

tat phrase makes a lot of difference if the fons mobo got sot during warranty period, better get written clarification cause repairing the mobo could cost a BOMB
