Huge crowds lined up for Samsung Galaxy S7 (Price Check) and Galaxy S7 edge (Price Check) smartphones because it is literally the best smartphone they ever made. Not only do they look amazing, Samsung brought back the microSD card slot. But arguably the most impressive feature about these two smartphones are their IP68 dust- and water-resistance rating.
Today, we are going to take a close look at the engineering behind the Samsung Galaxy S7 & S7 edge smartphones’ IP68 rating. We will also clarify its limitations, so you can enjoy your Galaxy S7 and S7 edge smartphones for many years to come!
Samsung Galaxy S7 IP68 Engineering
The challenge with making the Samsung Galaxy S7 (Price Check) and Galaxy S7 edge (Price Check) smartphones water-resistant isn’t just ensuring that water won’t get inside. Quite a number of devices already do that, like Samsung’s own Galaxy S6 Active smartphone or the Kenxinda Flattop ruggerdised smartphones (Price Check).
What’s really amazing about the Galaxy S7 IP68 rating is how Samsung managed to achieve that in such a slim design. Best of all, you don’t even have to prepare it in any way before you dunk it into water. There is no need to cap the earphone and USB ports. It is dust- and water-resistant 24/7.
- An unspecified “new type of water resistance technology” was used to seal the unit internally against the ingress of water,
- An “exclusive type of water protective tape” was added to the back of the front and rear glass, as well as other internal parts,
- Rubber linings were used on parts like the USB port, the earphone port, and the SIM card tray to prevent the ingress of water
- Anti-corrosive materials like nickel and platinum and corrosive-resistant coating were used for all external metal parts and connectors like the earphone and USB ports,
- The USB port has a short circuit sensor to cut-off power when it detects a short circuit due to water contact
- Portable electronic vents were used to ensure a good flow of air and outflow of water and humidity
As you can see, a lot of engineering went into ensuring that the Samsung Galaxy S7 (Price Check) and Galaxy S7 edge (Price Check) smartphones are dust- and water-resistant, while remaining ultra-slim.
IP68 Rating Clarification
Officially, the Samsung Galaxy S7 (Price Check) and Galaxy S7 edge (Price Check) smartphones can withstand complete immersion in water up to 1.5 m in depth, for up to 30 minutes. That means you can take them for jogs in the rain, reading in the shower or soaking in bath. Heck, you can even take them for a swim!
There are some caveats though. The IP68 rating applies to a specific set of test conditions : 15-35 °C, 86-106 kPa, 1.5 metre, 30 minutes. If you exceed those conditions, Samsung’s IP68 measures may not prevent the ingress of water.
Water can also enter and damage the Samsung Galaxy S7 (Price Check) and Galaxy S7 edge (Price Check) smartphones if they are exposed to “water moving with force“. This means you should not place them under running water from a tap or a waterfall. Even ocean waves may exert enough force to drive water into their chassis.
In short, these are not waterproof phones like the Samsung Galaxy S6 Active, or the Kenxinda ruggerdised smartphones (Price Check). They are water-resistant, not waterproof, so be gentle while using them underwater.
