Hi,

I've a Onda V972 for about 1 year and after the upgrade to the Android version 4.2.2. I've several battery issues. 

After this upgrade the tablet just last 30 minutes after 100% charging - I could see the battery running down like seconds.

After this problem I've seen in the posts that many people are complaining about Onda original battery and some of them decided to switch it with the LG 12000 MVA. So I've decided to do exactly the same and changed my batteries 2 weeks ago.

So I was very satisfied with the results, once after the first charging (10 hours) the tablet was very good and had a use of it for about 8 to 9 hours without charging it.

However after the second or third time that I've charged the problems are back again. Now it doesn't charge until the 100%, just keep the 14% and it doesn't go up.

What can I do more...

I'm completely devastating with this and I said to myself that I will not spend any more $$$ to try to recover this "bad quality tablet".

Thanks in advanced,

Ricardo
