Ways to Waterproof Your Phone

One of the biggest inconveniences for smartphone users is getting your device wet. Whether it’s a spilled soda or an accidental drop into the bathtub, it leaves the user with a sense of despair while wondering whether their phone would still work. Waterproofing is even more important for people with active lifestyles who regularly travel to the beach or trek trails. If you’re thinking about getting a device which can’t easily get messed up by being submerged in water or even just getting spilled on, we’ve got you covered with this fairly simple guide.

IP67/68: What does this mean?

Most modern smartphones have IP67 or IP68 certifications attached to them. The IP in this particular case refers to the International Protection certification, which is a standard by the International Electrotechnical Commission (IEC). The first digit after the IP refers to a device’s resistance to dust or dirt. The 6 in particular means “No ingress of dust; complete protection against contact”, determined after an 8-hour test. The iPhone 7 is an example of a phone with this sort of resistance, although it is against dust.

Now, the second digit is what defines the device’s water resistance. A 7 means that “ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time”. The IEC defines an acceptably safe level of submersion as around one meter deep. This protection can’t last forever though, as the 7 rating guarantees up to 30 minutes worth of protection. As far as we could find out, the Samsung Galaxy S8 had an 8 certification, meaning it could last 30 minutes at a depth of 1.5 meters.

How to protect your phone from liquids

Before we begin, it’s important to define what you need or want for your phone. Do you need waterproof, or water resistant? Most waterproof methods are relatively more expensive than the water resistant treatments/methods. Also keep in mind that there are no foolproof ways of waterproofing your phone. If it falls deep enough into water, the technology will fail. The point is to have protection if you can’t keep your phone from getting wet.

Ziploc bad

If you’re in a hurry and need a really quick way to waterproof your phone, we suggest using a Ziploc bag. It’s the cheapest solution, and relatively hassle proof. For maximum efficiency, try using a vacuum-sealing device to vacuum seal your phone in the bag. There are Youtube tutorials on how to do this. The downside to using a Ziploc bag is that you can’t use the phone as easily as you could have by not putting it in the bag. The point of a smartphone is convenience, and the Ziploc method kind of prevents that.

Waterproof cases

If you’re looking to be able to use your phone even in high-moisture situations, you should look into waterproof cases. They come in many different designs, and make the phone relatively easier to use compared to a Ziploc bag. However, the best ones are fairly expensive, like this Ghostek Atomic 2.0 series of cases, which are sold at around 50 USD (depending on what kind of phone). There’s also the Otterbox Preserver Series Case, which is one of the more trusted names in phone protection. If this is the route you’re going, remember to test the case.


The future of water-resistant coatings is here. Nanotechnology has enabled the creation of water-resistant technologies for your phone. We’re talking no need for cases, bags, and such. They do this by coating your phone in super-hydrophobic substances, which literally mean that they make the surface coated incredibly hard to get wet. There are two categories in nano-coatings: The DIY ones, and the ones where you send your phone out to the shop to get coated professionally. The difference is the thoroughness, and the price. The latter option uses vapor to thoroughly coat your phone, and is relatively more expensive. A good example of the shop-coat is Liquipel. This is NOT guaranteed to completely protect against submersion though. If you’re looking to go swimming with your phone, check out NeverWet. You can order it on Amazon for around 20 USD and is fairly effective according to multiple reviews. However, it needs to be reapplied consistently. Some other product names with good reviews are Nanostate and Impervious

So there you have it, the possible ways of preventing a liquid disaster to your phone. Of course, there’s still the option of just taking good care of your phone and keeping it out of harm’s way. It is an investment after all.
