is my phone normal? i fully charge in the morning before i go out and when i come back around 5 the battery is nearly empty. i didnt go online. just few calls and sms.

3g - off
edge - off
push - off
auto brightness - off
brightness at 1/4

FYI i have some startling discoveries on my iphone 3g OS 3.0.

Battery life goes from 100% to 0 in 12 hours with no wi fi usage some calls and sms on this settings:-

Push - off
3g - off
wi fi - off
location services - off

But this is my third day with no wi fi usage and just sms and calls with this settings

push - on
3g - off
wi fi- on
location services - on

Now i really wonder why. *shrugs*

tried everything but cant get past half a day at most 1 day without calls and sms with my old settings. with new settings i can easily get 2 days minimum.

don't think it's a problem. the phone will use power str8 from the electric socket once the battery is full. there's no risk of overcharging.
