No issues with iPhone 15. All of them have been fixed, I can assure you. Get that one.

I heard only good things about how strong 13 Pro/Pro Max performance and battery are. I went through a lot of videos when deciding to invest in the new iPhone 15 Pro and I was left surprised how good the 13 model performed. If these are your listed options, please go for the 13 Pro Max. You won’t regret it. In a year, you would have higher battery health than me with my 15 model. I know that for a fact :))

Bro for me magsafe takes ages, with USB-C + 20W it takes 45 minutes. Just plug that badboy in if you don’t want to complain for battery health issues anytime soon.

Not experiencing your issues. Also, if you live in a EU country, you have customer’s protection law covering you to return the product. If you live in a 3rd world country, I’m sorry for you, you should have spent your money more wisely on something else.

Also please note that the technological innovation graph pretty much flattened over the years, don’t expect any new changes even for the next 5 years too! Right now the biggest bottlenecks are batteries, but since they work via chemical reaction, material researchers need to find a new way to store power.
