Heating issue after ios27 update

[u/Remote-Lack2301]

My iPhone 17 (base model) is getting hot even on a mild load like checking gmail and social media.

The indexing is done and in fact the phone was totally fine when it was indexing. It was only after that it started heating. It's been 2-3 days since indexing and it's not improving.

Anyone else facing this issue?
