Hi all I've had a 5s since last October (ordered it on release day), things have been ok battery wise until recently. Basically I have to charge it twice a day, once overnight and once when I get in from work. I do the usual check emails (via safari), browse Facebook, send a few texts and play one game (empire Z), that's it, and these are not often - once twice an hour - tops. I have turned off background app refresh and GPS and the battery is simply rubbish. I had a live chat with a guy from Apple last week who did a diagnostic and told me my battery was fine and that I had an iOS corruption and that I needed to back up phone, reinstall iOS and then restore my phone, so I did this, and battery was still as rubbish. So I spoke to them on live chat again and she arranged a Genius Bar visit today in Milton Keynes (I am northampton so a 30 min drive up the M1). I get there, she does a diagnostic, shows me some pretty little graphs and says battery is fine, this time install iOS and don't back up to old phone. To say I am annoyed is an understatement. Waste of time, petrol and miles in my new car. Question is this, what if I reinstall (I could have lied today) and the battery is still poor? Will they swap it out? The manager in store was very rude and straight away refused to do anything apart from raise a complaint against the girl I spoke to who arranged the Genius Bar visit. Anyone got any advice of similar woe?
