Samsung Galaxy S2, battery drains too quickly now?

[Beth-Anna]

I've had this phone since November. I dropped it in December, the screen smashed. It worked fine until a few days ago. I would charge it to 100% (leaving it overnight) then within half an hour it'd be at 50%? I only use Twitter, and Facebook Messenger. My battery used to last all day. Now it wont even last through 6 hours of school. Is it because I use a kindle charger? I only use it because it fits my phone.
Is the battery broke? How can I fix it?

Thanks x
It's also constantly on energy saving mode, and my brightness is all the way down 24/7.

Same thing with me. Although mine is in fine condition the battery drains quick. Put energy saving mode on and decrease the screen brightness.

You do not have to fix it as it is not broken or any stuff. Just stop using using so much fb and other messengers. Because they make your cell-phone run many scripts and also many so they need a lot of energy for that. The charger is absolutely okay to use. Just use these social stuff less.
