What do we mean by Waterproofing?
Mobile phones and other devices designed to be waterproof, as well as dustproof, receive a rating from a group known as the International Electrotechnical Commission (IEC). The rating comes in the form of the two letters “IP” which stands for Ingress Protection followed by a two-digit number. The first number defines the level of protection against dust, dirt and sand. The second number refers to the level of protection against water.
The most commonly found rating is IP 67, the first number, 6 means these phones are impervious to dust and 7 is able to withstand immersion in water up to 1 meter, for up to 30 minutes.
There is no such thing as waterproof. There are multiple entry points for water to enter your phone in any given situation – speaker grill, buttons, ports etc. That’s why companies are so insistent on the phrase “water-resistant” instead of “waterproof.” And you should probably be warned that none of these manufacturers would honour their warranty if water-resistance fails.
The important thing to note, however, is that the IP rating of the device does not make it resistant to all and any kind of liquid. Pressurized water can easily breach the water resistance seal of the handset and seep in thereby damaging the internals. Similarly, salt/sea water is a strict no-no. There have been cases when people have reported rust developing after they took a swim near the beach.
1. Apple iPhone 7 / 7 Plus / 8 / 8 Plus and X:
Apple introduced water resistance in its lineup last year with the iPhone 7 and has continued the trend this year as well. The iPhone 7 and 7 Plus has an IP67 rating, which means the phone can be submerged in up to 1 meter of water for a maximum of 30 minutes, but anything over that may cause permanent damage to the phone. In fact, Apple removed the physical home button and replaced it with a haptic engine enabled scanner that imitates a click.
The overall design of the iPhone 8 looks the same as its predecessors, but the new Apple smartphones are built with a stronger glass shell on the front and back that is held in place with an aerospace-grade 7000 Series aluminium frame. The iPhone X too has the same rating. Keep in mind, Apple says these devices are splash/water resistant and not meant to be submerged underwater. The lower speaker grill is made to withstand minor splashes and cannot prevent a strong current from entering the speakers and causing permanent damage.
2. Samsung Galaxy Note 8:
Samsung designed the Galaxy Note 8 with durable aluminium and a solid glass back panel. The Note 8 has a 6.3-inch OLED screen with a 2960 x 1440 resolution. And Samsung ensured that the Galaxy Note 8 devices are resistant to water and dust (IP68 Rating). This is the highest level of IP certification available for consumer devices. An IP 68 rating means that the device is water resistant 1.5 meters for 30 minutes. In fact, there are many videos showing that the S Pen also works underwater along with wireless charging. The display becomes unresponsive underwater like every other phone out there so you’ll have to rely on physical buttons for clicking.
Other specifications include 64GB/128GB/256GB internal storage options, dual 12-megapixel cameras (one 12MP wide-angle Dual Pixel f/1.7 and OIS and one 12MP telephoto f/2.4 OIS). Overall, this is one of the best Android smartphones available in the market right now and absolutely worth spending on.
3. Google Pixel 2 / 2 XL:
Both phones have a Snapdragon 835 processors, 4GB of RAM, and an option for 64GB or 128GB of storage. They each have front-facing stereo speakers and OLED displays, the smaller Pixel has a 1080p resolution (441 PPI) and the larger version has a 2880 x 1440 resolution (538 PPI). They have a 12.2-megapixel rear camera with a f/1.8 aperture and optical image stabilization — an improvement over last year’s f/2.0 lens and electronic image stabilization.
Just like the iPhone’s, Pixel 2 and Pixel 2 XL come with water- and dust-resistance ratings of IP67. The Google Pixel 2 and Pixel 2 XL do not feature a 3.5 mm headphone jack, which means you’ll need to rely on your USB Type-C port for wired headphones.
4. Samsung Galaxy S8 / S8+:
The Galaxy S8 and S8+ feature IP68-rated water and dust resistance. The IP68 rating indicates that the Galaxy S8 and S8+ is water resistant up to 1.5 meters (4.92 feet) for 30 minutes.
The devices are powered by Samsung’s own 3.0 GHz Exynos 8895 processor alongside 4GB of RAM and 64GB of internal storage expandable via a microSD card (up to 256GB). Both models come with a 12-megapixel rear camera with OIS and an 8-megapixel snapper on the front. The Galaxy S8 sports a 3,000 mAh battery and weighs 155 grams, while the Galaxy S8+ comes with a 3,500 mAh battery and weighs 173 grams. Lastly, both smartphones come with facial recognition support, an Iris scanner, Samsung Knox, Samsung Pay and earphones tuned by AKG.
5. LG G6:
Just like the S8 and Note8, LG G6 is IP68 Rated, meaning it is water resistant up to 1.5 meters (4.92 feet) for 30 minutes.
