Will charging my Iphone X i it's case hurt the battery?

So I know it's recommended to take off a case while charging your phone to reduce excessive heat. However I finally got around to buying an Otterbox for my X. Anyone who owes Otterboxes knows taking them on and off can be a pain and will sooner or later hurt the rubber outside and put strain on the plastic clips and break those eventually as well. So knowing all that, is it a big deal? Or should I try to keep the room i'm charging the phone in cool?

No it won't. Virtually nobody takes their case off to charge their phone.

Dimming the brightness may help a bit
