I've just bought my Razr, but I am very disappointed with the duration of the battery. Today, for example, I charged it until 100% in the morning and went to work at 8am. I didnt turn on bluetooth, 3G or wireless, but at 6pm the battery was low. Can this be possible? Is it a defect of my cellphone? Cause I really cant think it is normal, I almost didnt use it but the battery didnt last 12 hours. There is anything I could do? I am really disaponted.
