anyone know how you can build a water-resistant phone with a removable battery?
Many phones are water resistant with manufacturers guidance as to time and depth of water it can survive, eg iPhones https://support.apple.com/en-us/108039
As far as I’m aware, after you go to Apple or Samsung for a official battery replacement, there is no advisory issued to say the repair affected the previous level of water resistance
A: add a gasket.
B: glueseal everything except for the battery, connected via exposed gold pads.
The only thing that will change as far as I know is that battery won't be glued anymore. You'll still have to open the phone with screw like you did before.
If you've ever swapped a battery in a phone you would know that there are special battery adhesive foils for DIY battery swaps that have a tab that lets you pull on the adhesive foil and thereby remove the the battery much more easily.
Nothing like that will change, not with this regulation, which already exempts any waterproof device like a waterproof phone. Per the article:
> The iPhone was already exempt from the removability rule under the original regulation, thanks to its battery cycle life and water resistance rating.
The issue is people thinking they need to use maximum power to RIP it out, damaging everything in the process.
You need a constant slow pull on the adhesive, which heats it a bit, causing it to release cleanly.
