Stupid maybe generous q but need opinions on this!

So guys I have 13 pro max, and want change my life to come back to android after 5 years :D

I just wanna use max out of my phone as I can and I came up in my head a idea with using google phone (like idk how they called but seems good to me - they have literally higher specs than my iPhone rn), I really like using gemini overall and find out it cant on my iPhone pair my google things correctly, idk why but its so irritating to me.

So I want to switch to newer hardware out there, I have 512gb rn and I filled in 5 years only like 400 with everything /never cleaned/ and I dont want to transfer my files to desktop cuz that will be hella long night with the work around it :D - there is chance of loosing files when changing battery for brand new

so I am ready for your opinions, sorry for my english if its bad / wrong spelling etc
