The snippet “if the batteries have a shorter lifetime than the appliance” worries me. Seems to me that modern engineers are capable of making their crap’s lifespan just barely shorter than the projected batty lifespan, and people might just be stupid enough to still buy it.

I mean, the disposable vape market is an extreme example, but somewhat relevant I think.

That being said, if the processor on the LG G5 had kept up with the market better, I don’t see how that couldn’t have been a starting point.

As for waterproofing, my GoPro stays waterproof but the side door opens to give access to the SD card, battery, etc, so it’s absolutely possible.
