On DT A-330 im getting wrong informations from Battery Utility:
1- There always info saying "charging" even when im using it on battery :]
2- Indicator informs that full charge gives 91% on percentage bar, strange.
Thanks for using my app,
It will always say "charging" even when it is not chaging.
The only time it changes its text is when the dingoo is fully charged.
In fact I did not implemented this because I got lazy to test GPIO info...
I dont have a DTA330 to test, but, probably the default battery values are different, look at the "battinfo.txt" and change the max value to 4000 and calibrate to 1, it will probably fix your problem =)
