Call Quality

We had no considerable issues with call quality on either phone. Both the S8+ and S7 Edge are decent.

Both phones also support voice over LTE (or VoLTE). Carriers that offer this feature will be able to deliver much cleaner and more pleasing audio via the earpiece.

Battery life

Very good battery performance, but turn Always On display off if you want to get the most out of the battery.

To find out about the Galaxy S8+ battery life, we put it through our standard test that allows us to compare all phones on equal grounds: with the screen set to the same level (200 nits of brightness, comfortable for typical indoor use). Luckily, the Galaxy S8+ does very well in this test and even though it is not the number one battery performer, it is certainly above the average for flagships these days. Note that we have tested using the Full HD+ resolution that our phone came set to by default (1080 x 2220 pixels).

The Galaxy S8+ battery life test result stands at exactly 8 hours. Compare this with the 7 hours and 18 minutes that the already good Galaxy S7 Edge scored, and you see that Samsung has managed to improve on their last year's phone. The S8+ also bests the Google Pixel XL, the OnePlus 3T, but falls a bit short of the battery life on the iPhone 7 Plus.

In a nutshell, the Galaxy S8+ and its 3,500 mAh battery turn out to be a very good combo (that lasted even longer than the S7 Edge with its slightly bigger, 3,600 mAh cell). Despite fears that a 3,500 mAh cell might not be sufficient to guarantee a solid battery showing, we see that Samsung has managed to do quite well.

Another important aspect of battery usage is the time it takes to fully recharge a battery from 0 to 100%. The Galaxy S8+ supports Samsung's Fast Adaptive Charging and it is able to fully recharge its battery in just 1 hour and 40 minutes, exactly as long as the S7 Edge. This is not the fastest we have seen, but it is not too far off. The Galaxy S8+ also supports fast wireless charging, which is a neat feature.

It’s time for a wrap-up: with every aspect of the S8+ and S7 Edge compared and thoroughly examined, is it worth getting the S8+?

If you don’t care about price, it’s a resounding yes for us. The bezel-less screen is the big feature and it looks futuristic, cool and useful. The slightly improved camera and battery performance are also something to keep in mind. Not much else has changed: the performance is faster, but we still see the occasional stutter, recharge times are not much faster, nor are there many other flashy new features. Bixby is a thing of the future that we could not fully test just yet, so we reserve judgment for the moment.

And then, for those who care about price, there is more to it. In the United States, the S8+ is not much more expensive when compared to the S7 Edge: it’s $30 per month over 24 months on Verizon vs $25 for the S7 Edge (or $25 over 30 months on AT&T vs $20 for S7 Edge). In this case, the S8+ is certainly worth it. The full retail price of the Galaxy S8+ stands at $825, but the unlocked version of the phone will go on sale later on, in May 2017. An unlocked U.S. model of the Galaxy S7 Edge currently officially retails for $670.

Looking at the price on a global scale, though, we see that the S8+ carries a full retail price of €900 vs €550 for the S7 Edge, and that is a much bigger difference in price than what we have in the United States. Considering this international pricing, a year after its launch, the S7 Edge represents a great value for the money. Unless you really care about the undeniably cool new Infinity Display, the S7 Edge is still an excellent phone, so we see no pressing reasons to upgrade..

In a nutshell, the Galaxy S8+ has our irrational sympathy: it’s good looking and futuristic, but if you are looking for the best value for the money, the S7 Edge is still worth getting.
