The battery life of my Book is complete rubbish.
Without using the wifi or wacom options I get about 600 page turns maximum whether I turn it off or onto standby between reading sessions, so 2 to 3 days between charging. I does in fact lose all power after about 4 days even if it is fully charged at the start and left turned off.
I tried a test for the last few days, I left it connected to a power source and in standby. It displayed one of the pointless pictures, ( I have no idea why they are called screensavers,) two or three times a day I have noticed the picture has changed or it is displaying the last page read. This implies to me that it is turning itself on and back to standby several times a day which may be accounting for the short battery life.
The fact that it can lose charge even when turned off may also be due to it turning itself on and off even when supposedly totally off. It has behaved this way with several firmwares.
It would be interesting if anyone else's Boox displays the same defect.
