Okay, I know I posted something like this before, but I can't seem to find it! Anyhow, for some reason my iPad-2 battery appears to lose "optimization" ie. battery life periodically, maybe every three months. When it is optimized my iPad runs for days on one charge, right now it is lucky if it can hold a charge for more than 4-hours. And I am not doing anything really different. I have let the battery completely drain, I have restored things through iTunes. I am at a loss. Any ideas? Thanks!
