Hi, In the past week the battery % of my iPhone 5 will be anywhere from 25-50% charged, yet I'll get a random shutdown...then when I try to turn it back on, it'll show me the "plug-in-your-dead-phone-to-a-charger" screen. If I wait about 15 minutes the phone will turn back on, but the percentage will drop rapidly. Anyone have any advice for me on this? I will be away over the next few weeks without access to a GeniusBar, so I would like to get this replaced in 1 visit. The last thing I want to do is go into the store and have them tell me that I need to reinstall iOS...try troubleshooting, etc........ Anyone here experience something similar with their phone?...and how did Apple handle your service? Was it easy to get replaced? I want to get this replaced ASAP and not have any hassles with it while I am away. Advice would be great on how to handle the Genius Bar. Thanks!!
