Getting annoyed with this, Battery life was rubbish on iOS 5.0.1 so I set up as new phone, no difference, turned of iCloud, no difference, and today I went to the hassle of installing a brand new battery thinking it was a battery problem but again no difference, Took the phone of the charger 30 mins ago, checked twitter and emails and the phone is already down 10% from 2 mins of use and just sitting idle. Any ideas?
