I actually thought of trying this out after reading the post on yomiprof and it worked well far beyond my expectation. The total power Facebook app comsumes is nothing good to talk about. Deleteing the Facebook app will increase your battery life by 20% and possibly deleting the Facebook messenger will also go a long way increasing your battery life.
Tech World Zone recently tested the Facebook app on a Nexus 6P using Metal. The results of the test showed that for an entire week, removing the Facebook app left the phone with 20% more battery life each day.
So after deleting your facebook, that does not bring an end to your Facebook account as you can always use Facebook lite or use normal browser to access your Facebook account.
