I bring my phone into the bathroom on occasion when taking a shower so I can queue up music on the bluetooth speaker in there. I leave it on the sink and sometimes just throw a hand towel on it to keep the steam off it. Or I just reach over with wet hands and change tracks if I want. It’s IP68 rated (which means 1 meter of full immersion) and it’s never been an issue at all.

I also accidentally walked into a swimming pool a few years ago with an iPhone 13 Mini in my pocket. I was afraid I’d destroyed it but all it did was complain about the lightning port until I left it to dry overnight. ¯\_(ツ)_/¯

Ehh, while you’re correct in a strictly technical sense, what most people refer to as “steam” (that is, the visible cloudiness swirling around a hot shower or rising from a pot of boiling water) is mostly liquid water that has already condensed in cooler air.

By the time you’re seeing steam, there is already an excess of water vapor. In a bathroom, this vapor has likely thoroughly infiltrated the phone.
 
I have taken my caseless phone to steam room for past 5 years. Never had any problem with my 13 PM. Stop worrying and use the phone. They are waterproof unless you are blasting steam directly in to your phone port.

after taking a shower, I noticed when I type, it stopped making the typing clicking sound whenever I type. What should I do? I checked the settings and it was enabled. I think this happened from the steamy shower room.
Water that gets into the speaker mutes it way down, especially the lower frequencies. It gets back to normal once it has dried.

I heard it may damage, would waterproof pouch protect from steams entering into the iPhone?

Why can't you just read the spec page!? It's waterproof.

I rinse my iPhone almost daily because of sweat / ocean water (I don't use any kind of case), 0 problem.

If your concern regarding “water vapor” was correctly placed, we would routinely see devices failing from prolonged exposure to typical indoor humidity, since all air has water vapor that can theoretically get inside the device and condense. Obviously, we don’t.

It’s rare for water vapor to condense inside devices, and certainly near critical components, both due to limited ingress points and the fact that most devices are a good bit warmer internally than the surrounding air (yes, even in a bathroom with a hot shower running).

If you see steam, condensation is occurring on its own outside the device. Again, liquid water intrusion is by far the primary concern in this case, but steam generally isn’t going to damage devices rated IP67 or IP68, as most iPhones these days are.

The steam you see in the bathroom, that’s condensed water vapor.
…also better known as liquid water.

No. Because there's a third factor called dew point.

When running a shower with 99% humidity, the dew point spread is something like 5°C. The iPhone has to be within a few degrees of the ambient temp or else condensation will form. The iPhone internally is not 45°C but maybe 30°C. Condensation will form.

As a glasses wearer (your profile pic), you probably know and experience condensation and dew points.

The dew point spread in a normal room is like 15°C.

This is basic science not even up for debate. Apple literally says avoid:
  • Using iPhone in a sauna or steam room
  • Operating iPhone outside the suggested temperature ranges or in extremely humid conditions

Fun fact, it’s not my day job but I’m a degreed meteorologist, and I definitely do not need water vapor and dewpoints explained to me. But thanks, I guess!

Condensation still requires the device to be colder than the dewpoint of the surrounding air, which an iPhone in a bathroom (again, even with a hot shower running) is generally not going to be, because the RH drops off faster than you seem to think it does as you move away from the water.

Even in a poorly ventilated bathroom, the RH in the room at large should be high for indoor environments but not near 100%… probably 75–90% or so. Air is constantly moving and mixing, and unless the room is small and well-sealed during a long, scalding hot shower, the only spot in the room where RH exceeds 95% is probably within half a meter or so (at most) of the shower water, much like the entire room’s air temperature doesn’t skyrocket to the water temperature of ~100°F.

I think you overestimate the device temperature and ventilation of a bathroom.

Most people won't be sitting on the throne playing Genshin Impact for 30 minutes before taking a shower. The iPhone temp will be close to indoor ambient temp, or around 22°C.

If the bathroom temp is 35°C during a hot shower, the dew point will just be a couple degrees lower, guaranteeing some condensation.

Many people shut the bathroom door and leave the exhaust fan off because they're lazy and don't want to feel cold after stepping out.

The exterior of the iPhone should be near room temperature (likely slightly warmer) unless the device is under heavy load. Even then, the interior should be at least several degrees Celsius warmer, maybe even more while the device is being used.

To put some hard numbers on this, per coconutBattery, the current battery temperature of my fancy ✨vapor-cooled✨ iPhone 17 Pro Max (while not doing much) is 28.7°C while the ambient temperature is about 21°C. That’s the only way I know of offhand to get to the internal temperatures of an iPhone, but it provides a pretty good glimpse at what I mean. Even the lowest-power, coolest-running devices we have still run a good bit warmer than room temperature. They have to. And if they’re streaming music or scrolling TikTok in the shower, that temperature difference will be even greater. Also don’t forget that the device will warm somewhat (both exterior and interior) as the ambient air warms. This shouldn’t have a huge impact on the temperature difference, but the difference might grow a bit due to heat stress on the battery.

So, to get condensation to occur inside the device, you need dewpoints well north of 80°F / 27°C through the entire room. Have you experienced dewpoints that high? Having lived my entire life in the southern U.S., I have. If you haven’t, trust me when I say you don’t want to. That’s air that’s so humid you start to feel woozy just standing there because you can’t cool off; sweating becomes futile as evaporative cooling slows to a near-halt.

Most people don’t willingly subject themselves to this when showering. Why? Because bathrooms don’t get quite that hot and humid while showering.

Your temp data comes some of the hottest parts of the iPhone - the battery which is next to the SoC.

Where's the speaker? It's furthest away from the SoC, likely close to room ambient temp 21°C.

What you've described in the U.S. is nothing. Live in Southeast Asia during monsoon season. Those periods are known to kill electronics if not significantly reduce reliability.

Ignore the science. What do you think happened to OP's iPhone 15 Pro Max after showering for two years? A ghost changed his audio settings?

The OP said that their phone is working perfectly - including all other sounds - apart from the keyboard clicky sound.

Sounds (hah) like a s/w problem not a h/w one.

I've not done any research on this, but I would guess most software errors are caused by bugs rather than ghosts, although I'm not so sure about iOS 26.

Edit: Could be an iOS 26 issue.

Op are you sure it’s humidity problem not something else. If iPhones had issue with being in bathroom, it would be a wide spread problem. I have had no problem taking them to steam rooms 5 days a week for past 4.5 years.

Iphones are not and never have been sold as waterproof. Quoting the IP68 spec appears to be a feature, bit its a guide.
They are sold as water resistant, and not permanently and not warranted. Read the small print in apple.com. That means 999/1000 will get away with getting it wet, but if it does leak, that's tough on the owner. You pay for a new phone, I won't take the risk.
And Watch? Apple says do not use in the shower!

Do not take a shower with iPhone on you. It’s not uncommon for people to put the iPhone in the bathroom.

Don’t take it into the shower room and the shower room won’t cause it any damage.

i agree, however "rinsing" a phone is very risky, and if the OP's phone is already affected in keyboard sound then it is already compromised with a shortened life. If a rice bag is indicated, a new phone is not far away.

He did?

In general, when there's moisture in the speaker, the higher Hz sounds will be affected more. The low frequency bassy sounds push the diaphragm harder and are less noticeable.

Prevent humidity by using a ventilation fan, window, or keep the bathroom door open. Not only is this more healthy but it eliminates your issue. Nonetheless, consumer electronics are safe to use in humid environments (within limits). Apple publishes this information on its website. Furthermore, iPhone and Apple Watch have a water resistance rating.

I also play music from my iPhone in during showers. No problems have arisen and when I traded in my previous model, Apple didn't reduce the value. I think this is enough evidence that the humidity isn't going to cause damage. If my memory is correct, Apple trade in involves an internal inspection for water damage.
