All smartphones, including iPhones, must have replaceable batteries by 2027 in the EU::undefined

There are a few phones that have removable batteries with good water resistance. No phone is completely waterproof, so I don’t really care whether It can withstand 1 meter of water for 5 minutes verse 10 meters of water for an hour. It’s not like I am taking my phone snorkeling.
The Samsung S5 had an IP rating of 67, which can withstand temporary submersion and had removable batteries. I frigging loved that phone.
