Call Quality

Call quality is excellent on both the S7 and S7 Edge, and we find them identical as well in this regard. Voices sound clear and well defined on both ends of the line. The earpieces are also sufficiently loud, but in case you happen to spend time in louder than usual environments, then there is the neat ‘extra volume’ mode that further boosts volume.

Speakerphone quality is not ideal, though, with its biggest flaw being that it is just weak and not loud enough to properly hear in louder conditions.

Battery life

The S7 Edge lasts a bit longer, but both score below average on our battery test.

The tech community was all abuzz and ecstatic about rumors of a much larger than typical, 3600mAh battery cell on the Galaxy S7 Edge. The rumors turned out to be true: the Galaxy S7 Edge does indeed come with a 3600mAh battery, while the Galaxy S7 also has a bigger than most in its class, 3000mAh cell.

Quite disappointingly, though, actual battery life on the two phones is not really the revelation that many had hoped for.

We put the Galaxy S7 and Galaxy S7 Edge through our custom battery benchmark and the phones scored around the middle (and even a bit below) of the pack.

We test non-stop typical smartphone use and the Galaxy S7 scored 6 hours and 37 minutes until its battery was fully drained. The S7 edge did a bit better at 7 hours and 18 mins, so its larger battery does provide a bit of an improvement over the S7. That’s shorter battery life than those of the iPhone 6s and 6s Plus, and also shorter than what Samsung’s own Galaxy Note 5 scores.

The two phones support Quick Charging and using the stock Samsung wall charger, you’d be able to top up their batteries very fast: it takes about an hour and a half to fully recharge the Galaxy S7 and 10 minutes more to fully recharge the battery of the S7 Edge.

Battery life (hours) Higher is better
Samsung Galaxy S7 edge 7h 18 min (Average)
Samsung Galaxy S7 6h 37 min (Average)
Charging time (minutes) Lower is better
Samsung Galaxy S7 edge 99
Samsung Galaxy S7 88


Last year, we wondered: why did Samsung even make two phones that are nearly identical?

This year, there is more of a difference between the S7 and S7 Edge: the S7 Edge is larger. But is this enough of a reason for both phones to exist? Samsung has done a commendable job squeezing the 5.5” display of the S7 Edge in a very compact body for that screen size. With the richer Edge UX functionality, slightly better battery life, and overall more modern form factor, we still feel that Samsung could have easily just released the S7 Edge and called it a day. It’s the better phone all around.

Still, at a starting price of $750, it’s a bit more expensive than the S7 and for those who really want a smaller phone, it provides an option that is equally powerful and with equally great camera. If you want the better treat, though, the S7 Edge feels like it.
