I have my 6S Plus since 3 years now and I will get an XS Max soon. *happy* My 6S Plus will stay alive. Are there people too who upgraded from 6S/7/8 Plus to the XS Max? If yes how would you rate the battery life? The battery of my 6S Plus has still %100 health, no long battery life like at the first days. But I’m curios bc the newer iPhones have OLED and the better processors.
