Help Weird battery drain randomly on and off

[Kelgorus]

So both of these were with the same usage, I have tried factory reset, wifi/GPS/Sync/LTE is off with both of these ...

I have had to stay on HSPA+ the entire time I do not realize what to do any more!

This is it on a pretty good day:

This is it on other days:
I even had to switch off data around 30% because I was still out!

Do I give in and buy a larger battery for it even though it will make the phone so much heavier or is something really weird happening?

I can see the Facebook app is there. Have you by any chance logged into the chat section with the facebook app and not logged out? I did that once and my battery drained in just a couple of hours. Thought my phone had gone crazy.
Do you have Auto brightness? Might save on battery

Yes I have auto-brightness on.

I do not know why Facebook would be draining it that much more, I have background data disabled for it

I did check it a bit more than usual today but I was also on the internet less so I feel like it should be the same amount of use haha. x_X
