I did a search and read where it is recommended to charge a new extended battery to 100% with the phone OFF, then turn it on and run it down to 15%, then turn off and charge again.
Here is my question:
Won't that initial 15% reading be based on the original battery? In other words, won't there really be much more than 15% battery remaining on an extended battery when the meter tells you there is only 15%?
My new extended battery arrives tomorrow, and I want to get the most out of it.
