Gaxaxy Tab 2 7.0 battery insanity

I have a new Samsung Gaxaly Tab 2 7.0. After a few days of use the charge characteristics of the device have become bizarre.

While the tablet is NOT plugged in, the battery indicator slowly INCREASES until it hits 100%. Then it drops to 1% and warns me that the battery is critically low. If I ignore this, the charge indicator again slowly creeps UP (remember, it's still not plugged in).

Here is a screenshot of the Battery History since yesterday:

Notice how I only plugged it in briefly the first time this cycle happened.

The battery indicator is basically completely worthless. I have no idea what the actual battery strength left is. And I don't trust that it charges correctly.

Has anyone seen this? Any idea what is going on? Any idea how to fix it?

Thanks.
 
hi MudCamper,
Did you every get this problem fixed? i have the same issue with my tab 2 7.0 as you have described. :-\
if i plug it in in the night, the tab works the whole day, but the indicator one time shows 'recharge' low battery, next minute it is at 65%. its totally unreliable. very fustrating, i am learning to ignore the battery indicator/alerts. But would be good to solve this issue.

Thanks

Check your charger. Might need a new one.

Clearing system cache in recovery may help too.
