Okay so here's my story: Got my iphone 5 about 2 weeks ago. Perfect condition out of the box, and looked like I had no problems at all. On my first charge to 100%, I got about 8-9 hours of usage (was almost straight usage, cuz first day). The next day I charged it to 100% again and that day, 3-4 hours of usage later and I was out of battery. I thought it was because I spent a while playing games so I did nothing. The day after that, again 100% gone within 3-4 hours of usage. Now is when I thought something was wrong, so I booked a genius appointment. He told me to restore it and it should fix the problem. Restored it that night, and the next day 100% gone in 3-4 hours. Another genius appointment and this time, a replacement. My replacement had somewhat of an improvement, 4-6 hours of usage. But still this was being on wifi for 60% of my browsing so I knew something was still wrong. Tried it out for a week to see if anything would improve, but nothing. Went back to geniuses, and he said he was going to try a DFU restore and that it fixes the problem 19/20 times (9/10 wasn't enough). After the DFU, while setting it up I noticed the screen was flickering. The kind gentleman had glasses on and sad his sight wasnt the best, so he took it to another genius for confirmation. That genius said that the screen was definitely flickering, and bam, replacement. Now this 3rd one is still getting the same terrible 5-6 hours of usage, even being on wifi most of the day. I don't really know what to do, should I bother making another genius appointment? Not because they're not helpful, all geniuses I've talked to were very nice and did what I thought was their best to try to help me. But can they do anything at this point? Should I just deal with the battery life and bring a charger with me, and if in a month I have the same problems, go talk to geniuses and hope the replacements have been fixed? Opinions appreciated.
