I spend almost time on Facebook, Fb2Mate game, Messenger, Youtube,…
I have to charge my battery 3 times a day.
Should I replace the battery?

Facebook app causing severe problems (December 2016 app update)

Since its last update, the Facebook app causes severe problems like phone freezes, crashes, battery drain, problems with instagram etc. (see here for example) If you lately experience issues like this, just uninstall the app. Probably your problems are solved.
