I am having similar problems with my 6S+, but I don't think Facebook is the issue because the battery drain still occurs when I totally close the Facebook app. Interestingly the battery drains abnormally quickly when the device is in use, but not when the device is sleeping.

When my new iPhone 8 arrives I am going to run the 6S dead flat, then factory reset it. If that doesn't resolve the issue then I will call Applecare as it still has three weeks of coverage remaining.

I will post here if I make any useful discoveries.

instead, use the web browser version and just make a shortcut to that on desktop

facebook was also the culprit of bad battery life a while ago because they had a bad update

Thank you for that! I was wondering why FB was suggesting all these people I had never heard of. What a stupid 'feature'.

For my case, that does make sense to me about facebook being the culprit. But I'll never know for sure.

I was amazed how quickly the battery was draining. But as I say, it wasn't for too long and the problem corrected (probably after updating facebook to a corrected version).

The only times when my battery drains are when signal is poor, or when I'm out of data (presumably the thing keeps trying to get something from the internet).

That said I keep background apps OFF.

THe other thing I can think of is GPS - something might have been allowed to use GPS "At any time, even when the app is not running"

I once used an app called "Here NOW maps". That thing never shuts down unless you shut it down, so it was navigating me all throughout the 5 hr wedding reception and luckily at the end of it I remembered the way back home at 1 am)!

I have been unable to track down the culprit. I deleted FB as suggested but no difference. The battery App is giving no real useful information. IOS 11 is due in a few days, I think I will ride it out a do a reset and clean install as such then and see what happens.

Here is a crazy notion, lets give peace a chance.
