I read just recently the same thing to condition the battery, I always thought lith ion batteries didnt have a memory. But I want the most battery from the maxx so I am doing what they said.
1st charge battery fully, then use phone till battery is allmost dead, fully charge again and use to allmost dead, then one more full charge and then till allmost dead.
dont know if it work or make a differnece, but im on my second full charge, I fully charged it before activation and then I tried to kill it. charged it full by 1:00pm on friday afternoon. loaded everything on it I had on my DX2, played with it all friday night (the phone) lol then used it most of saturday listening to xm radio doing chores. surfed the net, txt, email through out. on sunday morn at 6:30 it was at 5 percent. its charging now, we'll see.
would love to hear from anyone in the know.
