This morning I left for school with a battery of about 80%. I didn't use it heavily throughout the day (with the somewhat frequent texts, one phone call and listening to music for a total of 2 hours throughout the day) and now that I come home 6 hours later, the battery is 13%. Yesterday I left home with about a 50% battery and came home with about 5%. When I'm at home I turn off my cellular and turn on my WiFi and when I go out, I turn off my WiFi and turn on my cellular. The battery doesn't die nearly as fast on WiFi as it does on cellular. Is this normal? I got the phone 5 days ago brand new when I renewed my contract. My old LG Xenon never died as quickly but that's probably because I kept it off most of the time.
