If you do not know, iPhone has moisture indicators at the top and bottom. So, if you accidentally drop your iPhone into water, the warranty will not cover it. However, in this experiment, it shows that even if the iPhone is within the manufacturer’s specs, the moisture indicator will turn red. So, if you are in a cold country, ensure that you protect your iPhone from the harsh condition. See the (quite boring) video after the break.
Watch this video of the tests conducted and let me know if you think that they are fair judgement.
