Hi guys, the battery of samsung galaxy 3 is faulty. Generally it is made in china and has serious fault. U can use only its 30-40 % power, after that it discharges to shut down. My battery lasts hardly 10 hrs which creates frustration and bcs of my busy schedule i cant visit any service station. The only solution to this is samsung must take initiative to replace all batteries. They r aware of this problem but only ignoring the matter for the profit. But this may leads to short sales of their phones. I m really frustrated to buy this phone and always have to carry charger. I m changing to htc now. Poor samsung.
