Many repair shops will put old or cheap batteries in your phone. Even if they buy an expensive one they don't necessarily know what it is.
There are a lot of waterproof connectors on the market. They pretty much all work but if a standard is chosen it will absolutely be one that works.
I've used a good few battery powered tools, even cloths. If any manufacturer made [say] a drill with a glued battery I wouldn't use it if you paid me for it. You just walk to the charger, swap the battery and get back to whatever you were doing. There is nothing special about phones that deserves special consideration.
I wonder if the battery can be smaller if you can easily bring a few extra. My cameras have very small ones 700mah-ish specially when compared to the size of the camera. It is never a real issue. Just bring more batteries. Say phones have 4-5 times the mah and last 8 to 30 hours. You could slide on a battery with a bump and get 60 hours or a slim one with only 4-15 hours. That will eventually outperform the degrading cell.
I don't know where innovation is at but I imagine we could see new batteries with much better size to power ratio. If you already have the newest phone it would be a no-brainer.
