Plus, the bulging rear door that would be required is a turnoff.
May need it in emergencies where you aren't able to charge it. If you live in SoCal or anyplace where has possible earthquake dangers, or any type of natural disaster in general you may need one. Towers may be knocked down and your phone would need to use more juice to get to other towers. Talking about worse case scenarios here, you could never have too much battery life... as for me, I sometimes forget to charge my phone at night when I go to bed, it's be nice to wake up and see a bunch of juice left in your device to last your that whole day.
