Have you tried looking into battery replacements?

If you really want to go back to android then sell ur 13 and buy an s23 or wait for the s24

No hate to Samsung but the iPhone 13 is miles better than the 21, I had the s21+ and I had barely 6 hours SOT can’t imagine that with a smaller battery

Something like routines from Samsung

Photos under good lighting have been more or less the same for 5 years on all brands, so by only looking at photos it’s not gonna be a VERY noticeable upgrade

They’re not bad, they’re different and you just don’t like it because you got used to Samsung’s processing. I use an iPhone and a Galaxy and both have basically the same video, just different processing.

It works on my Samsung Dex, perhaps this is an iOS issue
