I bought an iPhone 5 when it first came out, and it worked wonderfully well until the appearance of iOS7. I downloaded it and the phone just became a buggy nightmare. My top 3 complaints: It won't sync twice with my PC (the PC/iTunes just says I should reset it to factory and cannot read the phone...then I do, then it works, then it goes back to the way it was). There is a huge battery drain despite not running things in the background, the battery goes down very quickly, I plug the phone into my reserve battery and *poof* it's back up to a normal level. The phone is saying it's low when it's not but it is indeed refusing to work when it thinks it's low. Siri...she only offers to go on the internet and look things up for me, she has been useless. I did not buy Apple Care and so I have gone to my Apple store to consult "geniuses" multiple times with no lasting effect. I have combed the internet to try just about any incantation or ritual or suggestion which might vaguely work, no dice. Nothing works and many hours have been squandered chasing my tail. Perhaps I do have a faulty app from long ago somewhere...I have so many apps it would take a lifetime to weed through them (more wasted time). So, I am hoping that the second complaint from above points to the fault is with a defective iPhone and that a new one will give me hours of iPhone bliss. What do you think? Faulty iPhone? A bad app? Something else? What? The phone has had a pretty good life, always in a case, dropped but not badly and with no/little sign of wear. No water damage. I am hoping that the iPhone 6 will solve all my problems. What bothers me is that it was working perfectly until iOS7 and then phffffft, none of the subsequent updates have done any good.. That points to an app incompatibility but I dread that answer. Any thoughts on the subject would be appreciated.
