Switch from iphone 15 to s24 ultra

Hi, I’ve been an iPhone user since 10-12 years now. (Not really part of the ecosystem). Currently Ive an iPhone 15 since about a year and the battery is killing me, also not a big fan of 60hz display. I did consider 16 pro/pro max but didnt find any major changes to spend big. So now I’m considering s24 ultra as I believe its worth the value.. I’m a heavy user 6-8 hrs a day, i dont play games but mostly scroll reddit/twitter, social media etc. my main questions are: how is the battery life and camera? Also, i believe iphone has a better resale value, but how is it for samsung flagship phones? Any input would be valuable :)

Edit- Also forgot to mention, I’ve never used a phone with more than 6’1 screensize. Thanks

Update- bought the s24 ultra right now! Time to explore and hopefully get used to android:) Thanks everyone for their inputs, much appreciated
