I had the same troubles as you and switched to Folio Pro this week. It has very similar customization options as Swipe, so after some tweaking, I can barely tell them apart. It's made by the same people as Friendly, an app others recommended.
I bought it because I liked the app. But tbh I can't even remember what the difference is between free and pro. I think the pro may have more themes? It's currently on sale. https://play.google.com/store/apps/details?id=com.creativetrends.folio.app.key&hl=en
The Facebook app still sucks battery. I use Folio Pro All the features of the mobile site. Can also wrap Twitter, Google+, reddit, tumblr. Great dev.
I mentioned this before but it's generally recommended to remove the Facebook app entirely and replace it with a mobile site wrapper (which is more convenient than always having to access it in Chrome). I recommend Folio. I've been using it for maybe 7 or 8 months and since the Nougat upgrade I have not had any battery issues (I'd go as far to say my battery life has improved). However last time I brought this up a number of people said they already don't use the FB app and still have issues.
I also have the official Reddit app installed, though I probably don't use it as much as other folks here.
