LG 4X HD big battery problems
I have a problem on my LG 4X HD. The battery consumption is very high. I tried to charge it 100% and when I unplugged it, without doing anything, the battery drops to almost 40%. I've been watching on it for the last few days and the battery seems to dropping. I even activated the power saving mode. Though it helps a little, the battery is still having the same issue especially when it drains. What can I do? Does it needs replacement?
