Had a fully charged battery by the time I went to bad last night. I know this because I was constantly checking the baseball scores through the MLB app. Then I went to bed, and next thing I knew I was already an hour late for work. My alarm didn't go off. Just to carlify, I haven't used a traditional alarm clock in about 5-6 years. Just always used the alarm on my phone because I know if the power goes out my phone still has a battery that can last through the night. Now after this epic failure, I want a different phone. I know it's sad to say that I want a new one after a little mishap..but now the phone seems unreliable to me. Going to look into getting the Incredible.
