No. Factory waterproofing is a nanopolymer internal coating that's applied via pressure after the phone has been assembled. When you disassemble a waterproofed phone, you break that coating and weaken the protection. You won't fully destroy the protection; you're just weakening it at the places where you've taken things (including screws) apart.

On the bright side, some stores (like mine!) have the necessary equipment to restore that nanopolymer coating after a hardware repair has been made. It's inexpensive and quick to apply, typically taking less than 10 minutes.

Do you have a recommendation for a place that offers that service in Los Angeles?


Contact the folks at and ask them if they have any installations in your area. That's the device I have.

Unfortunately no. To replace the battery you must remove the back which will break the water resistance seal. You should also be careful because those back are very fragile and prone to breaking when coming up and if they don't break the paint likes to peal.
