Hello. I've got serious problem with battery, almost can't use reader. I bought it 2 month ago, did 2-3 full charge/discharge cycles (except charging while copying books), lifetime was about 2 weeks. Two weeks ago i started to use device only for audiobooks for a week, until i've found reduction of lifetime from 3 days (using player) to 1 day, so i stopped listening and deleted all mp3's. But lifetime still was reducing quickly to a hour of reading (100 pages). Moreover, after full charge, when i disconnected USB, it showed immediately 3/4 battery, now it's only 1/4 just after disconnect. Charging (red light) still takes ~1.5h, i disconnected just after red light is over, so there was no drain by USB cable.
I formated memory, removed SD, cleared settings, reinstalled firmware, tried to charge via PSP adapter, but all of this have no effect. Now after full charge and 10-20 pageturns i get "low battery" message, and 100 extra turns before shutdown. I'm thankful for any ideas.
