I got this phone in September. I'm having such terrible battery life it's not even funny. On a normal day I'll charge it through the night and unplug it to take it to school at around 8 am. When I get home at 3:30 battery is at 20% from normal use. Today I've used my phone for 3 hours for texting music and purchasing one song on itunes. It's now showing 10%. Is my phone the issue. I had brightness at 50% and had wifi and location services off. I'm frustrated because it's impossible to make it throgb a day without plugging it in as soon as I get home. I'd appreciate some advice n how to go about dealing with this. Should I try to get a replacement?
