Whereas some go DIY , some go those 3rd party shop replace.

My Question here is preferring doing battery replacement at Apple store even those 3rd party shop. Some claim even those replace their battery at Apple store. They mention once the iPhone been open for battery replacement and seal back. It will not say 100 percent water resistant like been seal back in Factory.
