I perpetually keep my Hotspot on my phone on. For family members and my spare phone. It doesn't drain the battery in any noticeable way.

To me it's weird and so much friction to try figure out wifi Hotspot and password and login. Makes me feel like a homeless poor person, as if I can't pay for my own mobile data.

I didn't have internet at my house for a week and had to use my phone hotspot: the amount of heat my phone generated greatly increased while the battery life greatly decreased.

If you're not noticing a drain on your battery from keeping your hotspot on its because no one is connected to it / using it.
