Call Quality

We had no issues with call quality on either phone. Both the S8 and the Pixel do a great job in terms of call quality with clean and crisp sound that is loud enough on both. If you want the best quality, we advise you to have the volume a couple of stops below the maximum level on both, as you do get some distortion at peak levels.

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

Both are solid battery performers that will easily last you a day, but the Galaxy S8 is the one that goes a bit more on top of that.

The Galaxy S8 features a 3,000 mAh battery, while the OnePlus runs on a 3,400 mAh cell, but the Galaxy has also got a more power-efficient processor and the latest AMOLED technology, so we were very curious to see which one does better in terms of battery life.

We’ve been using the OnePlus for a few months now and it gets solid battery numbers: it will last even heavier users through a full day, but it’s not quite into two day territory. Put simply, very few phones are, so that’s not necessarily a downside. At the same time, the OnePlus 3T did way below average on our test and this means that its battery does not last long when you use the phone for browsing the web.

The Galaxy S8, on the other hand, delivers very solid battery results all around, in both testing and real life use. We get a day and a half with it on average, and if you are a moderate user, you will be able to go through two days on a single charge. The Galaxy S8 wins in terms of battery life.

Then, both phones also support quick charging: the OnePlus uses its proprietary Dash Charge and is able to fully recharge its battery from 0 to 100% in just 1 hour and 25 minutes. The Galaxy S8, despite its smaller battery, actually takes 1 hour and 40 minutes to go from zero to 100% hero.

There is one thing that draws a clear line between the Galaxy S8 and the OnePlus 3T, and it’s not the camera, the battery or the software: it’s price.

Put simply, the Galaxy S8 is the much more expensive phone! The full retail price of the S8 is set at $720 in the United States, while the 64 GB OnePlus 3T costs $440 and the 128 GB one is priced at $480. That’s nearly a 50% price premium that you pay for the S8. And the price difference is much bigger in markets outside the U.S.: in Europe, the OnePlus price starts at €440, but the S8 price there is actually €800, nearly double the cost of the OnePlus.

The biggest thing that the OnePlus lacks is the ‘wow’ factor: you pick up the Samsung Galaxy S8 and you see a futuristic display unlike anything that’s been out before. You pick up the OnePlus 3T and you see a very good phone with a very good camera, battery and performance.

The Galaxy S8 design is really something special: it is both the looks, but also the narrower screen that is so much easier to use with one hand that it feels like a 5-inch phone despite the much bigger screen.

For all else that’s worth, these two feel like phones of the same class: the OnePlus has the slightly better camera, while the Galaxy has the better battery life, both are equally fast in terms of daily use. The OnePlus is slippery and not so comfortable to hold due to its bigger size, but the Galaxy has that weirdly positioned finger scanner.

Bixby is a non-factor as it’s not completely out yet and the optional DeX dock isn't good enough to be a desktop replacement, even for lighter users.

So yes, your mind will certainly tell you to save a few bucks and get the OnePlus, but your heart will probably want the Galaxy S8. We usually go with the heart, despite the mind protesting, but it’s up to you to make this choice for yourself.
