i've had a quick search but can't seem to find anything about this problem so i apologise if i'm creating a duplicate thread..... i went to bed last night with the battery showing 40%, i woke up this morning and it was at 14%. i looked at the usage and the standby times and they were both exactly the same (16 hours 31 minutes or something like that). basically my phone was being 'used' while i was asleep which has never happened before (unless it was a ghost that was desperate to play with the 3g s). i had a few pages open within safari but nothing that auto-refreshes and i closed all of them and turned the phone off and on and now the usage time is staying still while the standby time is climbing (which is what i would expect). i guess it could have been the pages within safari but can anyone confirm or deny this? it's not a huge problem as the restart solved it but if anybody knows what might have caused it can they please let me know so i can avoid it happening again. thank you.
