I was looking in the FAQ and didn't see what I was looking for. I wanted to test how long I can get out of a full charged battery, but I've kind of read a little bit about the "deep discharge" where it hurts the battery. I was wondering if it's ok to leave the phone on Android all day, until it dies. Because I'll boot into android and then my battery will die quickly, but once I reboot, it shows that I still have about 50% battery left. So would it be bad to leave my device running Android till it dies? Will I have any trouble getting it to turn back on once it dies? Thanks to anyone who can help!
