I abhored anything to do with Facebook until this week.
I finally realized that I was loosing contact with a lot of very good friends from forums I frequent.
I succumbed and loaded FB on my cellphone.
So far, I have not been hurt by doing that except once. The day I installed it I just left everything "ON" just to see how bad FB is for trying to keep you sync'd up with all of your "best friends".
Well, in about 4 hours, it had pulled the battery down to 34%.
Okay, now it is time for me to fall back to my "Normal Mode" of using my cellphone.
Settings/apps/app mgr/download/Facebook
Turned Notifications OFF
Then I resumed my normal mode of putting my phone to sleep until the next time I want it.
I turned OFF the internet, period!!!
I have Battery Doctor installed and use their two Widgets to control the phone.
First, I close all apps.
2nd, I use BD's stop all running apps widget,
3rd, I use the Switcher Screen to turn off everything except for GPS (high accuracy mode) and rotation (for my camera pix)
The rest of it gets turned OFF each time before I click the Power Button.
I have my screen delay set to 10 minutes so that nevers shuts down during normal use. (what I call normal)
After I resumed "My Normal use" of the phone, my battery life went back to 2 days for normal use.
Or, if I turn on FB, or read CNN or BBC or leave the Google Maps on for 2 hours the battery will start draining at a moderate rate. Say down to 35% in about 10 hours?
But, I have a Qi Wireless charger installed and I just drop the phone on that charging pad when I get home from work. end of problem.
