I'm a new user to Android and I'm unable to understand battery charging indications. When I plug in the charger, there appears a thunder like symbol in my battery and the battery level animates from current level to top level. After sometime, it stays at top level. At this stage, does it mean it is fully charged? But the info below the time(at center) says "Charging" and there is no "Full charge indication". Please tell how could I detect if it is fully charged. Moreover, the battery in Galaxy Mini is worse and so I've to charge twice a day( 1 hr each time). Is this the real battery performance??
