Power off, charge to 100%, use to 15% battery warning. Repeat. And you're good.
NEVER kill the battery, turn it off before that happens or you could put it below the minimum threshold and with normal discharge, your phone may be permanently dead...
This battery hates heat, charge periodically throughout the day, short charges less heat. Don't step on the device, don't let the device go swimming no matter how much it asks,
Though it says its a razr, do not attempt to cut somebody with it.
Its not a hammer
Its not a tire tool....
And never toss it gently on a bed or couch, cause it will bounce off the wall, through a window, and probably injur a neighbor...:banghead:
DROID RAZR MAXXIMIZED!!!! PREPARE TO BE VANQUISHED!!!
