I don't know about battery issues but one thing i am sure is about the screen..it's really very awful!And Please don't speak anything against D10e,or you may get screwed up from Tenida..thank god..i somehow managed to protect myself from him.Well D10e has poor battery and a little bit dull screen, apart from that every thig else is par with all other Allwiner A10 based tabs, even xtab and funbook is also same A10 based tabs
