iPhone battery dying after few hours from 100% charge
Since I upgraded to the iOS 5.1 my battery life on the iPhone 4S has been ridiculous.
For example, I left my house at 740am with my phone on 100%, I have browsed a little (safari and facebook) for no more than 20-30 mins in total. No apps are not running in the background as I ensure to close apps once i have finished with them. And now at 1400 I am left with 28% battery. i am not due to be at home until 1900.
Have I been unlucky with getting a dodgy iPhone from Orange?? the model is MD242B if that helps.
Also, notifications and banners are all turned off except for phone, messages, whatsapp, remainders, calendar.
I am careful not to over charge my phone, I do use an app called BatteryDoc to monitor my charging.
I always let my battery go flat before charging to 100% (with no trickle change), i believe this is a normal charge and what BatteryDoc advises i perform a full charge..
I am slowly regretting this phone after 6 months now.......
any input is welcome.
