Since you powered it off and started the charging again at 20%, you never actually set the low battery flag (which is set at 15%). This time, let him use it until it reaches 15%, or if he gives it back to you before it gets to 15%, continue using it yourself. It is important that the cycle goes:
- Charge to 100% with power off,
- Drain to 15% (not lower) through normal use,
- Charge to 100% with power off,
Just in that order. The first charge to 100% sets the Full battery flag, the discharge to 15% sets the Low battery flag (hence the "Low battery" warning that pops up on the display), and the second charge to 100% confirms the range of charge from 15% to 100% to calibrate the meter properly. If you leave out any one of the three steps, you defeat the entire purpose for doing this calibration exercise as it will only add more confusing information to the meter and could result in further erroneous readings.
So, I got my new Maxx two days ago (w00t!) and never followed this procedure - never knew about it until I came back to the boards and started catching up on RAZR/Maxx threads. Is this solely for meter calibration, or is there something about the battery itself that requires the procedure for improved battery life/performance? And if it's just an internal app calibration (I also use Battery Left for that sort of info, btw), how can I "reset" the internal app and recalibrate?
