The Samsung Galaxy S7 edge Smartphone Review

Page 3 : Water Resistance, Liquid Cooling, Bigger Battery, Faster Charging

Water Resistance

The Samsung Galaxy S7 edge (Amazon) is IP68-rated for dust- and water-resistance. Best of all, you don’t even have to prepare it in any way before you dunk it into water! For more information how how Samsung achieved this feat, take a look at our Samsung Galaxy S7 IP68 Engineering Explained.

Officially, the Galaxy S7 edge can withstand complete immersion in water up to 1.5 m in depth, for up to 30 minutes. That means you can take it for jogs in the rain, reading in the shower or soaking in bath. Heck, you can even take it 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. Even so, water may enter and damage the Galaxy S7 edge if it is exposed to “water moving with force“, like running water from a tap or waterfall, or ocean waves.

In other words, this is not a waterproof phone like the Kenxinda ruggerdised smartphones. It is IP68 water-resistant, so you need to be gentle with it. You can read more about this in our article – Samsung Galaxy S7 IP68 Engineering Explained.

 

Liquid Cooling

One of the biggest complaints about the Samsung Galaxy S6 edge (Amazon) was how hot it gets during heavy use. This is particularly pronounced when it is used to record videos.

Samsung mitigates this issue in the Samsung Galaxy S7 edge (Amazon) using a “liquid cooling system” to keep its internal components cool. Samsung was not forthcoming with the details, but ifixit tore it down to reveal the liquid cooling system as a small, thin copper heat pipe.

A heat pipe is used to very efficiently remove heat from a hot surface on one end, and conduct it to a colder surface on the other end. It does this using a working fluid (like water) that turns into vapour on the hot end, and condenses at the cold end.

The Galaxy S7 edge’s heat pipe can be seen to run across the 4 GB Hynix LPDDR4 (which lays over the Snapdragon 820 / Exynos 8890 processor), and 32 GB Samsung MLC flash chip, as well as several other chips before terminating on the back cover.

Bigger Battery, Faster Charging

Samsung also corrected another major complaint by Samsung Galaxy S6 edge (Amazon) users – battery life. The Galaxy S6 edge only came with a 2,600 mAh battery. Samsung gave the Samsung Galaxy S7 edge (Amazon) a large 3,600 mAh battery1,000 mAh or 38.5% more than its predecessor!

How much more battery life can we expect from this larger battery? We tested it using PCMark and lo behold, the Samsung Galaxy S7 edge (Amazon) lasted almost 11 hours! That is almost double the battery life of the Samsung Galaxy S6 edge (Amazon), which lasts just over 6 hours on the same test.

Officially, the Galaxy S7 edge (Amazon) will fully recharge its battery (from 0% to 100%) in just 115 minutes. In our test, it took us just 86 minutes and 46 seconds to recharge the Galaxy S7 edge from 19% to 100%. If you look at the graph, you can see that its recharging performance is linear up to the 90% mark, then it tapers off. For maximum charging speed, you can charge from 19% to 90% in just under 64 minutes!

This battery recharging performance is thanks to the 15 W fast charging capability that both Samsung Galaxy S7 edge and Galaxy S6 edge support. The new Samsung Galaxy S7 edge (Amazon) improves on that by adding fast wireless charging! This allows you to recharge its battery wirelessly in just 155 minutes.

    Please do not buy Samsung S7. I have been facing problem daily at least once the phone getting OFF for at least 10 minutes.
    Since I lost the bill, the shop keeper is not receiving for repair or replacement. I have incurred a big loss buying the Samsung S7 cell phone.

    Thanks

      It seems that you may have a defective unit.

      Even if you lost the receipt, you can still try to claim support from Samsung directly. After all, the Galaxy S7 is less than a year-old.
