Performance comparison

If you want to see the differences between the S8 and S9 at a glance, check out our smartphone comparison tool! But if you want a more detailed comparison, the rest of this article is for you.

The Samsung Galaxy S8 has an Exynos 8895 processor while the S9 includes the improved Exynos 9810 processor. Both are fast and capable 8-core processors though, and according to the manufacturer, the difference in performance is between 15-25%. These aren’t incredible performance bumps from one generation to another. So it is one point for the S9, but the S8 is not outdone.

Additionally, both smartphones include 4GB of RAM, 64GB of storage and can accommodate microSD, microSDHC, microSDXC memory cards. However, only the newer S9 one offers the ability to insert 2 SIM cards at the same time.

Battery life comparison

This is an extremely important point when choosing a new phone. There’s not much point in investing tons of money into performance if the phone can't hold a charge for long. 

The Samsung Galaxy S8's battery offers longer life than the S9's. When talking, you can use your phone for up to 23 hours. That's excellent in our books, and does better than the newer S9 which can make calls for 16 hours straight. When it comes to all-round battery life, the S8 hits the mark with 12 hours and 16 minutes, compared to 11 hours and 18 minutes from the S9.

Both batteries have a capacity of 3000 mAh, fast charging capability and neither is removable. 

As far as battery life goes, the point goes to the Samsung S8.

Ergonomics and design comparison

While there was no revolutionary design change between the two models, one thing is worth noting: the S9’s fingerprint sensor has a much better positioning than it does on the S8. It’s a minor difference, but it will save you some frustration and awkward phone holding in daily use. 

Otherwise, their overall builds remain largely the same. In terms of dimensions, the Samsung Galaxy S9 measures 14.77 x 6.87 x 0.85 cm, while the S8 measures 14.89 x 6.81 x 0.8 cm. Really a minor size difference that you’re unlikely to notice.

Screen and display comparison

The difference between the Samsung Galaxy S8 and its successor’s screen isn’t that obvious either. Both phones measure 5.8 inches, which means they’ll fit comfortably in your jeans’ pockets. This may be a consideration worth noting given the rather large sizes of the latest smartphones. Both screens are Super AMOLED and boast excellent resolutions (2960 x 1440 pixels, 568 dpi). So if you’re looking to pick the phone with the best display, both the S8 and S9 will provide similarly excellent experiences looking at photos and videos or reading text.

Camera comparison

Here again, Samsung has not provided any major changes. Both devices are equipped with a 12 MP rear camera and a 8 MP front camera, which are quite good for smartphones. Budding photographers will be happy with either of the two models. 

However, those with a keen interest in photography will enjoy the variable aperture on the Galaxy S9. This option allows you to set the aperture to either f/1.5 or f/2.4. This feature can make a difference especially if you like taking portrait photos.

The S9 also has a new video feature that allows you to shoot in Super Slow Motion mode at 960 frames per seconds, which is up to 32 times slower than normal 30 fps videos.

Audio performance comparison

Depending on how you use your smartphone, speakers can be a key consideration when selecting your next one. While it was difficult to tell the difference between the Samsung Galaxy S8 and S9 in many areas, audio performance does make the newer model stand out.

On the S8, speakers and sound quality were not a particularly strong point. With their poor positioning on the bottom, they weren’t very strong or clear. Now placed on either side of the screen, they offer a sound that’s nearly 40% louder. These new stereo speakers from AKG definitely give the S9 an advantage for those that use their phone speakers often.
