Facebook is the Single Biggest Reason Your Battery is Dead
 

I’ve always told people that you can increase your battery life dramatically by disabling Facebook’s background refresh — but it turns out, Facebook has found some sneaky way around this, and it’s doing stuff in the background even when you have background refresh disabled.

Note that this piece is all about iOS devices since that’s what I use, but Facebook makes Android batteries die too. I’m sure you’ll find solutions in the comments section for Android devices.
