Hi, new here. I got an iPhone 4 in August and had a battery issue....After about a month my phone would just power off with 30% battery life, then 40%, then 50% and finally 60%. I would go to turn it back on and it would display a battery drain and I would plug the phone into the wall charger and it would turn back on and continue charging from where it powered off. I took it to the genius bar and they replaced it with a new one, now I am having the same problem. I did a reset by pressing the home and power button but to no avail. Has anyone else had this issue? The guy at genius bar said he hasn't heard of it before. I was planning on resetting back to factory settings when I get home from work but wanted to see if anyone has experienced this before. Thanks!
A little background:
I only have apps that I use often, about 6 or 7 apps.
Never had contact with any form of liquid
Never experienced the overheating of the phone itself while charging or others.
I close apps once I'm done using them.
I use 3g more than wifi when using the interwebz.
Haven't dropped it or crushed it, etc.
I never leave it on the charger after it reaches 100%
