The Galaxy S9 has an aperture mode for low-light environments and another for brightly lit environments. Samsung Galaxy S9 has the same single-lens camera design as Galaxy S8 with 8 MP front camera + 12 MP rear camera. What's difference is that Galaxy S9 comes with iris diaphragm, which allows camera to receive more light at low brightness. Galaxy S8 is the first mobile phone with a wide focal length f/1.7 lens while Galaxy S9 has further pushed the figure to f/1.5 (the lower the f/ number, the wider the aperture), and could switch the aperture between f/1.5 and f/2.4. When you are in a very dark environment (less than 100 lux), the f/1.5 aperture will start shooting, so most of the time you're shooting on f/2.4.

While Samsung Galaxy S9 Plus comes with a dual-lens camera with 8 MP front camera + 12 MP rear camera (f/2.4 wide aperture) + 12 MP rear camera (telephoto lens), which allows Samsung Galaxy S9 Plus's rear camera automatically switch between f/1.5 and f/2.4 according to different shooting conditions.

Besides, both of Galaxy S9 and Galaxy S9 Plus can shoot 4K videos (3840x2160 @ 60 fps, 1920x1080 @ 60 fps, 1280x720 @ 30 fps) while Galaxy S8 and Galaxy S8 Plus can only record videos in 1920x1080 @ 30 fps. Even though the image resolution are the same 4000 x 3000 Pixels for all Galaxy S9/S9+/S8/S8+.

As for processor, Galaxy S9 comes with the latest processor called Snapdragon 845, which improves the performance by 40% or so. And Galaxy S8 is using the Snapdragon 835, which also make Galaxy S8 runs smoothly. The problem is that it is hard to feel the significant difference in speed between Galaxy S9 and S8. Also if you have used your Samsung Galaxy S8 for a year, you might start to feel that Galaxy is slowing down especially when the new Galaxy phone is released.

5. Battery: Galaxy S9 doesn't have significantly better battery life than Galaxy S8.

Actually Samsung has snot reinvented the battery on Galaxy S9/S9+, and in terms of battery capacity, both of the Galaxy S9 and Galaxy S8 have 3,000 mAh batteries while both of Galaxy S9 Plus and Galaxy S8 Plus have 3,500 mAh batteries, though the screen brightness of Galaxy S9 is 15% higher than the Galaxy S8.

The new AR Emoji in Galaxy S9 is like iPhone X's Animoji, which can combine your facial movements with animal expression (or cartoon figures in Galaxy S9). Actually, the current AR Emoji in Galaxy S9 is kind of creepy and it feels weird. If you want to upgrade your Samsung Galaxy S8 to Galaxy S9 just for AR Emoji, it is not worth it at all. And also if you want the similar experience, you can totally use the existing app called Bitmoji.
