Hey i would like to ask, if its possible to get the Iphone after battery exchange back to IP 67 ? So it could be waterproof again ? Thanks for your help

It is possible, but you will face 2 problems. 1: actually doing it. 2: Proving that the phone had intact water resistance before the repair. Most times water resistance is already damaged on an older phone and your repair probably won’t cover the damaged areas because you didn’t know.
