Samsung Galaxy S8 vs Galaxy S7


Call Quality

Samsung Galaxy S8 vs Galaxy S7
We had no issues with call quality on either phone. Both the S8 and S7 do a great job in terms of call quality with clean and crisp sound that is sufficiently loud.

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

Battery life

A slight, but noticeable improvement in battery life on the S8.

The Galaxy S8 features a 3,000 mAh battery, the same size as the battery on the S7. Both phones run Quad HD displays (but the S8 is tuned in software to 1080 pixels Full HD by default), but the S8 has the more economical system chip inside.

And this shows.

We tested the Galaxy S8 in both its models: the US-bound Snapdragon 835 version, as well as the Exynos one. We found that there is a slight difference between these two. In our standard test where we ensure all phones run at the same, 200-nit brightness level, the S8 Exynos scored some 8 hours and 10 minutes, while the Snapdragon version lasted 7 hours and 30 minutes. This is nearly a 10% difference in favor of the Exynos model. The Galaxy S7, on the other hand, scored way below that: it got around 6 hours and 40 minutes, and this is something that you can notice in your daily life with the phones.

While the S7 would somehow struggle to get through a day when you have to use your phone a lot, the Galaxy S8 has no such issues. With moderate use, both phones last a full day easily, but in that case the S8 can keep on going a day and a half, and even two days if you barely use it. All of those numbers we get with the Always-on Display option turned off.

Another important aspect of battery usage is the time it takes to fully recharge a battery from 0 to 100%. Both phones come with Samsung's Fast Adaptive Charging, but for some reason the S8 charges a bit slower, taking an hour and 40 minutes, while the S7 recharges fully in 10 minutes less than that. Both phones also support wireless charging (that is not as fast), and that’s cool to have.

Samsung Galaxy S8 vs Galaxy S7

So let’s draw the line and look at the price difference between the two. The Galaxy S7 comes with one big advantage: a considerably lower price. You can currently get the S7 for $20 over 24 months on Verizon, while the S8 costs $28 over the same 24-month period. The full unlocked price of the S7 currently stands at $570, while the S8 unlocked model will go on sale within a few months at around $720. In Europe, the price difference between the S8 and the S7 is much wider: there, the S7 costs €500, while the S8 retails for €800 – significantly higher.

Price considerations and weird fingerprints aside, the Galaxy S8 is clearly the more impressive phone. It is indeed impressive in the purely visual sense with that new full-screen display, but on the inside not so much has changed. The camera is only better by a small margin, the performance has also improved, but it’s not gotten as smooth as the standard-setting Apple iPhone or Google Pixel. The battery life is another slight improvement. We also appreciate the little things in the S8: the higher quality earbuds that come in the box, the plentiful 64GB storage and the DeX dock (sold separately) that turns the S8 into a desktop computer.

The Galaxy S8 has our subjective sympathy for its luxurious styling and display, as well as all these little things, but if you have to listen to reason alone and be completely objective, the Galaxy S7 is still a great phone on its own.

The S8 is ridiculously highly priced in India.

This time Samsung has tricked those in India who were waiting to buy s7 at reduced price.
I thought s7 would sell at 35k after s8 release.
But it seems the price is not going down that Much.

I received my S8 today. It's awesome and I LOVE the dimensions.
But, the lack of a removable battery and the price make the phone a FAILURE.
I would NEVER buy this phone. My company gave it to me for free.

IMO, is amazing how one generation of phones can so quickly date what was accepted as a good looking phone. I can't look at a phone with more then say 1/4" or so worth of top and bottom bezel anymore and not cringe.

S7 is good except for the very slow keyboard.

S8 is a stretched out awkward looking S7 period.

On paper these phones have great specs and look great but when it comes to day to day use they SUCK. The full glass is pretty, but it breaks...EASILY! And the repair cost is insane. The edge feature doesnt allow you to hold the phone without triggering active content like the ads which reside on the sides of the browser. Every phone gets dropped at some time, and all my previous phones did ok. The s7 and s8 break everytime. New glass and digitizer is a minimum of $350.
