Which phones? I ask as someone that's had to replace multiple phones after a trip through the washing machine.

Modern phone water resistance is incredible. I've even seen people literally swim with their phones and not even question if it was a bad idea.

Fifteen years ago, I had a Garmin GPS (admittedly not a phone, but similar form factor) that survived a week of knocking around the bottom of a raft.

The battery compartment had a rubber gasket and some very tight screws.

  • How much of the total volume of the device was the case/housing?

    I suppose the glue-everything approach is partly due to the desire of making a device very thin. There's no room for strong, load-bearing outer case, the internals are load-bearing.

    • I suspect manufacturing has something to do with gluing too. Afaik screws are expensive compared with glue, and their assembly involves slow humans or expensive robots.

    • It's been a long time, but the gasket itself was probably a millimetre or two thick, squeezed extremely tightly by the screws in the battery cover. It ran on AA or AAA batteries, and they took about about half or a third of the depth.

  • Honestly I'd expect that to be SIGNIFICANTLY easier to waterproof than a laundry machine. Partly because laundry is sometimes done warm, and warm softens materials (like gaskets), but mostly because laundry has surfactants that considerably reduce surface tension, making it far easier to slip past gaps.

    There is a good reason waterproofing claims are specific about the kind of liquid (usually just fresh or salt water, usually without significant movement (i.e. jets, like you get in a shower)).

Samsung still make the rugged Xcover range which has both replaceable batteries and waterproofing. And 3.5mm jacks too.

These devices are mostly sold in enterprise environments (eg field use, factories) and as such get a lot of wear and tear. But they hold up well. They're not ultra rugged but a good compromise. We use tons of them in our factories, we replaced DECT handheld phones with the Xcovers loaded with ms teams. Not an ideal setup (teams for mobile kinda sucks) but at least this way they can easily communicate with people in the offices.

Samsung Galaxy S5 was the last one that attempted it. IP67 with a removable back cover and swappable battery.

  • Yes, but IP67 is not nearly as water resistant as IP68, which all modern phones are for the most part.

    I'm not knowledgeable enough to know if IP68 could be achieved in a phone without glue. There's no clamping mechanism for the backs, they're just press-fit with small clips.

    • From a mechanical perspective ip68 is perfectly achievable mechanically and watches have been achieving it for a long time, however… with what sort of margins for the manufacturer and what sort of cost for the consumer ? Additionally a lot of them require pretty carefully adherence to instructions torques and tolerances to achieve the same waterproof rating. Personally I’d be very happy to have a phone that says, if you swap the battery you might lose the ip68 rating unless you follow the resealing process within tolerances.

    • My phone (A Furiphone FLX1, which is kindof a variant of a Gigaset GX6) has a removable back with a gasket and is IP68. One of their promotional videos had them change the battery on video then boot the phone and and unlock it underwater

    • Who cares though? Sealing the battery in makes the device less drop resistant. I somehow managed to avoid water damage to my phones for decades, while none of my phones managed to avoid being dropped in a way that would most likely be fatal to them if their batteries were sealed in - and yet most of them survived to this day.

      A phone needs to handle some rain droplets falling on its screen, anything more than that is a gimmick that's not worth the downsides it comes with.

    • Maybe as a society it's better for people to have replacement insurance than to have sealed batteries that make phones so disposable. I wonder if we've defined IP68 as a "must have" without considering the alternatives. I'm thinking the percentage of people who actually "use" IP68 over the course of their phone is pretty small...yet that "requirement" drives a huge design choice.

      I suspect it's a moot point. Makers have every incentive to drive replacement cycles.

  • Japan only, but KDDI/Kyocera never stopped IP rated phones with removable battery. TORQUE G07(2026) is IP65/68/69 rated with a coin key locked removable back cover.

    It also officially support submersion in seawater as well as cleaning with soapy water. Most glued phones support neither.

    • I googled it - nobody is buying that thing instead of a normal consumer smartphone. It's like a 'Panasonic Toughbook' in phone form.

  • You forget the Xcover and active lines which do IP68. They stopped making Galaxy active phones but the tabs are still there. The Xcovers too.

Back when replaceable batteries were the norm, I had two Blackberries that survived going through the washer and dryer.

> I've even seen people literally swim with their phones and not even question if it was a bad idea.

Which is funny to me, because even with an IP68 phone, I get worried if I even splash a little water on it.

I was wading through water with a 3310 in my pocket in 2006. Battery was fine and it worked after it was dried. There was a problem with the keyboard though but that was a cheap swap. And this was a phone without any water resistance.

Not really comparable perhaps - but I had a Ericsson t18s or similar that went through a full 60C cotton wash cycle (being on at the start of the wash) and was fine after drying off.

The thing is - if the battery had been destroyed, that could have been replaced...
