You ever wonder what happens when you leave an app running in the background? Many apps are harmless, but some are battery life killers...
Facebook is a social media app that continues to track user information while still running in the background. Normally, this wouldn't take a very noticeable toll on your battery life, but Facebook had a glitch this month that greatly enhanced the draining power of Facebook, destroying as much as 20% of your battery even when not in use!
FIX IT, FIX IT NOW!
With twitter flooding with complaints, Facebook fixed the glitch and the bug was acknowledged by the Vice President that it was a server issue. They have asked users to reinstall the application. That said, Facebook has suffered from numerous issues like this in the past, so always stay up to date.
Moral of the story - if you haven't updated your Facebook this month, do it! DO IT NOW!
