Hello buddies, I have purchased the handset in the month of July. I dont know if this is a problem which I observed yesterday as I wanted to change the sim card. After I change sim card I observed that battery is around 2%. Earlier it was above 50%. Now today this problem happened again as when I removed the sim card and replace it, the battery again drains out. Otherwise battery performs normally. no sudden discharge. Guys pls tell me wat shd I do? thanks.
