Can not charge battery when I connected with cradle

[thinboon]

I brought and used the 2nd hands XDA II. I'm not sure our XDA II is mulfuntion or it's normal case. When i connected with cradle the status of XDA II show "Charging" but when i see the battery status in percentage. It's counting down. Example 30% and count down to 29%.......10%(I'm not sure).The XDA II show the message "To prevent the data......bla bla bla". That's means it deos not charge my XDA II.

Is it same as your XDA II?

I'm waiting for your answer.

Cheer!
