PLEASE HELP ... I am getting angrier by the day, and my blood pressure is going through the roof !
Since installing iOS 6.1.2 on my iphone 4 like many others who have contributed to this thread my battery life has fallen off the cliff...... I tried restoring the phone.. No difference....
In desperation I called the apple help desk who said it was probably that it needed a new battery which i thought was a bit strange that the problem showed up immediately after downloading the update, but if I went to an apple store they would run a diagnostic test on my phone, which would confirm wether it was a dodgy battery or the software. However They failed to tell me that before anyone will talk to you in an apple store you must make an appointment .
So today (tuesday) i drove 40 miles to the apple store in Lakeside especially to get the problem sorted only to be told when I arrived that they couldn't help me as I don't have an appointment , and the first appointment would be Saturday late afternoon . Needless to say I have steam coming out of my ears........
I have read the various fixes on this thread but unfortunately they are all a bit too clever for me to attempt and just want someone to fix my *€^%<~~*y phone !
