I have deleted the facebook applications in my phone for 2 days. Just the app not stopped to use it I still connect to my friend with web browser like a Google chrome. I have followed that thing with some blogger who tried to measure how many baterry that Facebook app has used also the performance of phone with use the other app in his phone. He found something that importantly. He got the lifetime of battery a day back more than he expected and also got faster in the other app in his phone. That is why I have tried to do something like that. I think I got the same result like he got.
So, Let’s delete Facebook app in your phone.
