So after my sis bought Desire 516, she discarded her Canvas 2 Plus which I get to keep. But the battery is dead. On a full charge it works for 5-6 hours. So I need to battery for it. A good one. The batteries from MMX have real bad reviews, so a battery from other companies are appreciated. Also the battery needs to atleast be 3000mAh. Greater mAh would be appreciated.
