If you didn't know, the iPhone (like all existing smartphones on the market) has several humidity sensors hidden in the headphone jack/port for the USB cable and around the motherboard, their role is to detect possible contacts of the phone with the water. The problem with these sensors is that they are triggered if you use the phone in an area where the humidity is higher than 95%, that is in Hong Kong for example. The residents there have very large problems with the acceptance of iPhone terminals under warranty due to the fact that the area in which it is located has a humidity of over 95% and the sensors in the iPhone are triggered even during normal use of the phone. Between June 1 and mid-August in Hong Kong, the humidity rises above the critical point of 95%, and the sensors are triggered, practically for them this period can be compared to keeping an iPhone in a sauna for 2 and a half months.
I've never used it in the bath, gone swimming or anything like that," Hayward said. "Let's do it; many people do break the rules. But a significant number of people are making these kinds of reports. If the limitation is over 95 percent humidity, they ought not to be selling the product here. I find it quite unbelievable – a real piece of corporate greed or a great oversight.
The problem is not only found in Hong Kong, but also in many other Asian countries, and even in California, USA, where a woman sued Apple for refusing her phone under warranty due to a triggered humidity sensor, the woman claiming that the phone did not had contact with water. The security mechanism is good in theory, but in practice the situation is not so good because there are many cases in which those sensors are triggered by themselves, without human intervention.
4 iPhone models left the gates of Apple's factories with the same type of sensors, and if Apple hasn't changed them so far, I don't see why they would do it soon.
What happens if those sensors are triggered?
It changes its color to red and refuses your warranty.
And how do I find out if they have been triggered?
You look with a flashlight or something with a smaller bulb in the port for the headphones and the one for the USB cable. You should see the sensor, it's white. Search for a video on YouTube and you will see what you need to watch.
Only the USB one is red, probably from when I spilled coffee on it.
Then goodbye warranty.
