i have an Ainol Hero 10 with almost same problem... i don´t know if it´s a firmware problem(1), a battery problem(2)or a physical problem (3).
summarized: the battery status display in Tablet a value between 1% and 11%, even it was connected to charger all night and day.
(1) I read a lot of forums and a lot of threads about convenience of upgrading firmware to correct problems like mine. i made 3 changes to firmware to my Tablet. it went with firmware 1226. first i downgrade to 1115v2 -i read about most stable versión- and after that i had a completely chinese Tablet.very funny to me when i originally receive a very good -international- looking Tablet. It didn´t correct the problem. then i read more and more -that guy Christian Troy is a kind of superhero!- and decide to move to 0128...and got a bizarre Tablet with problems in g-sensor... and still a error in battery status display! (not funny). At least, i´ve changed to firmware versión 20130308 and get a Tablet with some chinese apps, no g-sensor problem.. and add a wifi trouble to the bettery status problem.. Crap!!!!
(2) in other fórum i read about problems with batteries problems in connections, ensambling and mesurements. In open my Tablet -very easy, if you ask!-and take mesurements with a multimeter and batteries give about 7.3-7.8 DCV...everything look normal for me. not an answer there.
(3) also read about charger problems, ensambling problems and same in previous point, take mesurements to charger, connections inside the Tablet, and in my minimun knowledge looks normal...
at this moment i have no answer to it... so i need the experience of all of you to fix this issue, i believe that´s a very common problem, only not very informed!
