The Samsung Galaxy S9, as we see here, is not much of an upgrade compared to the Samsung Galaxy S8, but there are a few key differences which we will give more details later. The major differences worth noting are the operating system, and the camera – both of which are better in the s9, but still reasonably good in the s8.

  • Differences Between the s9+ and s8+

1. Software and Hardware: Let’s Take a Look Under the Hood

One of the major differences is the software the devices come with. The Samsung s9 is shipped with Android 8 otherwise known as Android Oreo. This is the newest major update for Android. The s8 does not ship with Oreo and comes with Nougat instead, which is Android 7. 

However, this really isn’t something to worry about, seeing as there are not a ton of major differences between the two systems that could hinder the use of your phone. You also have the option to upgrade to Oreo from Nougat on your Samsung s8 as soon as you set up your phone.

The processor on the Samsung s9 is also just marginally better than that of the s8. Both of Octa-core processors and have mostly the same performance. The s9 is slightly better with a processing speed of 2.8 GHz while the S8 has 2.3 GHz.

If you purchase from Glyde, both phones also come unlocked, meaning you can use them on any of the major US carriers. This is great if you have multiple SIM cards or you have not chosen a plan but you know you want the phone.

2. Pictures and Video: Picture the Difference

The Galaxy S9 does have the edge on camera quality. First off, the Samsung S8 does not have the super slo-mo feature that the S9 has as well as lower frame rates compared to that of the S9 for HD video. There is more of a trade-off with the S8 since the higher the frames of the video, the lower the quality will be. This is not as much of a problem with the Samsung S9 since the camera is better.

The front-facing camera of both phones is exactly the same. There are no quality differences between the Samsung Galaxy S8 and the Samsung Galaxy S9.

The rear camera of the S9 is better than that of the S8. The biggest difference between the two is that the aperture on the S9 has a 1.5 and 2.5 mode while the S8 only has the 1.5. Otherwise, the cameras are relatively the same aside from a few performance tweaks.

3. Size: Does it Matter?

The answer is a little complicated. The Samsung S9 is wider and thicker than the Samsung S8, but only marginally. The S8 is a little longer than the S9 but it also is not by much. The screen size is still the exact same between the two. The difference is so marginal that you probably would not be able to tell the difference just by looking at the two phones side by side.

The Samsung Galaxy S9 weighs a bit more than the S8 but only by about 12 grams, hardly noticeable unless you were to put them on a scale.  

The two phones, without a case, are extremely light, and you will barely be able to feel it in your pocket. With a thickness of fewer than 9 millimeters, the phones are also super thin. This is great if you are constantly trying to squeeze your phone into your pocket.

4. Battery: Hypnotizing Power

Actually, both phones have about the same amount of battery life. Both come in at 3000 mAh. How long the phone lasts on one full charge depends on how you’re using it though.

Both phones have 20 hours of talk time meaning you could be on a call for 20 continuous hours with no other applications running before the phone would die. Both also have 12 hours of battery life while using 4G data. This is pretty nice since you can go about a full day out and not have to charge throughout.

Samsung also packages its Fast Charge phone chargers with all of their phones. This really shortens your charge time. Throughout your day you can charge for a few minutes while not on your phone and have plenty of battery for the rest of the day. 

5. Display: Dazzle Your Eyes

The Samsung Galaxy S9 and S8 both have 5.8 in screens which take up the majority of the front of the phone.

Both displays are equipped with Super AMOLED which means that they both have fantastic resolutions and display beautiful colors.

They are each 570 ppi (pixels per inch) which means clearer images and you will never notice a single pixel. The color contrast on these phones is fantastic and especially good for streaming your favorite movies and TV shows.

6.Prices: Which One’s Cheaper? 

A used Samsung Galaxy s9 is $589.99, while a used Samsung Galaxy s8 is only $489.99. The extra hundred dollars really depends on the type of camera you want. The s8 is great, but there is a noticeable difference in the rear camera in the s9 that makes it much better for photos and videos. 

7. Difference Between Regular & Plus: One Size Does Not Fit All

The Samsung Galaxy S9+ does have a few key differences such as a larger display and larger storage capacity. Those are really the only major differences between the two though. The plus is much better for people who have trouble reading the small text since the screen size is 6.2” for both the S9+ and the S8+.

Overall Review: Finding the Right Samsung Galaxy for You

If you are looking for a phone with a superior camera, and a larger display, with faster speeds, and are willing to pay up for these features, the Galaxy s9 is definitely the best option for you. It comes with Android 8.0 (Oreo), and has a large memory for storing all the high-quality photos and videos you can take with the amazing HD cameras.

However, if you can make due with a decent camera minus the slo-mo features, with a bit smaller memory capacity – but one that is still reasonable, the Galaxy s8 is a perfectly good option as well. It still has a very reliable battery life, comes with Android 7.0 (Nougat), and also features a nice camera that still takes high-resolution photos.

Both phones have 4G capabilities and share a lot of the same features such as battery life, Bluetooth, wireless charging, and processors. The dimensions are slightly different between the two phones, but the size difference is hardly noticeable with the naked eye.

The s9 is a bit more expensive, but ultimately you are paying up for the camera. Just about every other feature besides the operating system is the same between the Galaxy s9 vs. s8. Both phones have a wide variety of colors, and are very affordable if you purchase premium used.

What About the Galaxy s9+ vs. s8+?   

Both phones are larger than their standard counterparts. The 9+ is slightly larger than the 8+ primarily in weight. It’s approximately 10 grams heavier. The batteries size and capacity is the same.

The real difference is speed and the camera. The 9+ has a faster processor as well as more internal RAM. It comes in at 6GB of RAM and the 8+ only 4. As apps become more sophisticated and video quality continues to pull more power from a phone the extra RAM does make a difference.

The 9+ also has dual cameras creating much better photography options. The video quality is significantly better because of both the camera and the processing power of the phone.

The differences in the two are small with the 8+ at a more attractive price point. If you want speed and video and photo improvements, the price point on the 9 is perfect.

What About the Galaxy S10: Is it Worth It?  

The S10 is a lot more of a significant upgrade from the S9 than the S9 from the S8.

First off, the screen size is a lot bigger. The Samsung Galaxy S10 boasts a 6.7” screen compared to the 5.8” screen of the S9 and S8.

The battery life is also a little longer than the 3000 mAh of the S9 and S8. The S10 has 3400 mAh which means a little more battery life than the other two predecessors. 

The Android OS is also newer with Android 9 (Pie), but both the Samsung S9 and S8 can update to Android Pie after the phone is set up. 

The catch with all of these upgrades is that the S10 is $400-$450. This is more expensive than the other phones listed and you should only consider this if the upgrades are worth that much to you. 

Newer model phones are always more expensive than their predecessors. The technology is not significantly better, but newer technology is still more expensive than old technology. Buying older phones is a lot more cost-effective especially since you are not losing any value with the phone. The S10 is marginally faster than the S9 or S8, but the parts are newer.

Which is Better, the Galaxy S8 or the Galaxy S8 plus?

The difference between the s8 and the s8+ is truly the size of the phone. If you love a larger screen and don’t mind a slightly bulkier phone then you will be happy choosing the 8+. The amount of pixels are the same even though the screen size of the 8+ is larger. Because of this you do have fewer pixels per square inch, but most people won’t notice the difference in crispness the small screen provides.

Which is Better, the Galaxy S9 or the Galaxy S9 plus?

The Samsung S9+ is better in a few key ways than the Samsung S9. It is larger than you would expect. Because the 9 is smaller, it does come with more pixels per space which creates sharper more lifelike images. The camera is where the Plus shines. There are two cameras on the back of the s9+. The second camera has a 2x telephoto lens. Because the phone is bigger, the battery is as well and even with a bigger screen, you get 2 hours more life out of the phone. The s9+ has 6GB of RAM compared with 4GB in the s9. The price is about $100 more expensive than the s9 as well.  

Is the Galaxy S10 Better than the Galaxy S8?

These phones are very similar but there are significant differences that could prompt you to upgrade if you are an s8 user. The s10 is bigger than the s8 both by height and width. It almost feels like a two-handed device and similar to the iPhone XR. 

Not only is the phone bigger, but the display extends deeper into the edge of the phone. In order to get the display right to the edge, Samsung included the front camera right at the top of the display. There is no separate fingerprint sensor. It is also built into the display. The display is crisper and uses newer OLED technology to present dazzling images and videos. 

Like any new device, the processor is faster. Samsung added a vapor cooling system to keep the device running at top speed without overheating. Both phones support wireless charging, but the s10 has the ability to charge other devices as well.
