I took it off the charger at 5am yesterday, decided to try out how long my batter will last me. I use it for two alarm clocks on for me and one for my boyfriend, texting, the news, email, facebook twitter, sudoku, use it when i go walking or running and keep track (endomondo), camera, a flashlight, a phone.
well mine i have my wifi on and use it when im at home and i mostly use my phone for bbm messaging and sometimes facebook and stuff and calling... my phone can last me up to 10 hours or more depending on how i use my phone but i can say it last pretty long for me
