Need a quick check. I have got my galaxy tab for more than a month and my battery can only last me 4 hours continuous gaming. Is this normal or something wrong with my device ? Battery log shows majority or almost 70% coming from the display but my display was set at 10% only. I hav e even install juicedefender but I don't think that it last longer.

Any advice ?

Other than this, I am happy owner of Galaxy Tab
