Since upgrading to an iPhone 15, I want to use my old iPhone 13 as a travel camera. Its eSIM has been deactivated. Has enough memory. How do I maximize battery life by disabling all non essential apps and settings that drain the battery?

iPhone 13, iOS 17
You can delete all 3rd party and some built in apps→Delete built-in apps from the Home Screen on your iOS 14 or later or iPadOS device or Apple Watch - Apple Support
Also enable Airplane Mode, and in Settings/General/Background App Refresh and turn off everything except Photos (this will allow the Photos app to sort and index new content).
