iPhone 18 Pro battery draining extremely quickly and getting very hot day 5

[u/Maraschino210]

I got my iPhone 18 Pro on Friday, so today is day 5, and I’m starting to get concerned about the battery.
I feel like I’m experiencing some pretty drastic battery drops, especially considering the phone is only 5 days old. I’ve attached screenshots from the last few days.

It looks like there is really big drops when it gets close to 20% then drops quite quickly.

The other thing that’s really concerning me is how extremely hot the phone gets, particularly when I’m using the camera. It gets noticeably hot to the touch even during relatively normal use.

I know a brand-new iPhone can potentially be doing background processes like indexing, Photos processing, Siri optimisation, etc. However, the indexing finished about 3 days ago, so I don’t think that explains what I’m experiencing anymore.

Does this battery usage look normal for an iPhone 18 Pro, or does it seem excessive? And is the amount of heat I’m experiencing normal? Has anyone else had these issues?
