It fell in the toilet. Your clumsy partner knocked a glass of water onto it. You forgot it was in your pocket when you jumped into the pool. That's just a few of the hundreds of ways your phone could come into life-threatening contact with liquid.
Fortunately, waterproofing has become mostly standard on modern phones. New iPhones, Samsung Galaxy devices, and Google’s newest Pixel phones all feature some degree of water resistance or waterproofing. How well a phone resists water is measured on an IP (or Ingress Protection) scale. If your phone is rated with a high number, like IP67 or IP68 protection, congratulations, it’s probably going to be fine! But if it’s got a lower rating, or none at all, you should prepare for the worst before you start chilling in the hot tub with your trusty Sidekick.
So when your phone decides to take a dive, as soon as you're done freaking out, you'll probably begin frantically tapping all the buttons, blowing on it, or blasting it with a hair dryer to quickly get rid of all that water. While those are all well-meaning actions, guess what? Totally the wrong approach. Here's the right way to rescue your water-damaged smartphone.
First, retrieve it as quickly as possible. If your phone is still in the bottom of the jacuzzi or the toilet, get it out ASAP. The longer it's in the liquid, the greater the likelihood of damage will be.
Once the device is no longer submerged, power it off right away. Don’t try to press any of the other buttons or load any apps, just switch it off. Remove the case if you have one. If you have a phone with a removable battery, pop the battery out. You want to cut off power in the device as quickly as possible to prevent the possibility of a short circuit. Most of today’s smartphones don’t have removable batteries, but some older models, or new models built with repairability in mind like the Nokia 1.3, let you pop the battery out.
