Hola,
Sorry I learnt spanish 25 years ago. I prefer speaking english (or french)
I've got a gift for you. I noticed that the discharge limit of the tablet is too high (3.7v) other tablets with lipo battery go under 3.5v . Modifying the limits will lead to 40 % bonus in lasting
So I decided to tweak the kernel with hex editor ( I don't have the kernel sources). Here it is my mod. The file must be unzipped and put a Cyanogenmod ROM.
After flashing your modified ROM file , the tablet will last longer and the charge time will be increased too.
Use at you own Risk !
The battery can explode etc ...
Cheers
Occip
