I have a problem with my Samsung Galaxy 3. Battery drops to 10% directly from 50%, with just one phone call (not more than 1 min). And gets charged to 50% directly from 10% when i put it to charge. I keep all data networks off. Have got the software reset from a Samsung Service center. Didnt work. So next time they replaced the battery. Didnt work. Next Time they replaced the mother board itself. Still the same issue. Now they say wait a month for Froyo. Anyone else having similar issues???
