cell dies quickly

[Android Question]

Hello I have a samsung Galaxy 2 slide and i fully charged it last night and within 3 hours it has died. I have no idea why it dies so quickly now. Before it would last all day and most of the evening.

How old is the battery?

You might need to buy a new battery. Unfortunately batteries don't last forever and over time don't hold a charge as long.
