Just want to throw an idea up to those with battery drain issues and the latest firmware. I have noticed a common theme with those people, they all seem to lock the Pocket Pro. I run the latest firmware and currently read mainly epubs. My current charge has just dropped to half after reading approximately 3000 page turns, but I don't lock the pocket pro at all, with a SD card in the slot constantly (though the books have been read since last charge from both internal memory and SD card).
So perhaps that could be causing an issue, the locking of the pp?? Just a thought (I have many, most are completely useless but the occasional thought is solid gold
)
