I have a 7+. In the last several weeks my battery has started draining super fast. I've uninstalled And re-installed Facebook a couple of times since I've heard sometimes that's the culprit. I don't plug my phone into a computer to sync with iTunes anymore and haven't for a really long time....everything on the cloud.

What can I try to fix this??

It's really hard to tell without knowing your app usage.

To start with, have you checked on the battery page which apps are using the most power?

Also, what permissions are given to the apps that drain the most? Background app refresh? Location?

Without knowing anything about your app usage, that is all I can really say.

In addition to the advice you already received - if you can't determine which apps are using the most battery you can always reset your iPhone 7+ from iTunes. Just make sure you have a good backup before you resort to doing that. That's what Apple advised me to do when I had the same problem with my 7+. The reset worked.
