Their products are reasonably priced, come with durable features, and are pretty reliable. The Samsung Galaxy S20 model is no more than the latest model from the Galaxy S segment. There are other terrific models that we have reviewed and will update you on.

However, the Galaxy G20 is not a device that can be easily written off. It comes with most of the features that you are looking for. The display is quite large, the battery working life is pretty good, and the processor is flexible for a wide range of users.

The new models come with a quicker processor, an updated UI, and a powerful battery. However, you can choose the S20 at a decent discount on most online retailers. Did we mention that it comes with a 5G compatibility and a quick 120Hz refresh rate?

You can find the Qualcomm Snapdragon 865 or Exynos 990. It depends on your locality, whether you are based in America or Asia. Besides, only some of you can get to lay your hands on the 5G compatibility device.

We may want to mention about the camera of the S20 device. Moreover, the 3 cameras found on the smartphone offer you spectacular clarity and quality. Having said that, the S21 model does come with a few tweaked features in it compared to the S20 model.

The Samsung Galaxy S21 model is a robust, reliable, and durable device. Though the camera quality may not be as expected, you would be delighted to know that the processor and the battery levels have been increased.

Samsung Galaxy S20 vs Samsung Galaxy S21: Design & Features

The design aspect is something that Samsung has been able to master over the years. You can note that their devices are luxuriously designed and come with an elegant appearance. Let us read and find out how the S20 & S21 devices did in the design & features segment.

The Samsung Galaxy S20 smartphone comes with a stunning design. It has a 6.2” display that is slightly larger by 0.1” than the S10 that was released in 2019. But, of course, that does not change the overall appearance of anything.

But it does make a slight difference due to the intense resolution. The resolution is the same at WQHD+ (3040 x 1440) as found on the Samsung Galaxy S models. You can make use of the default setting that is a battery saver.

Unless you want, you can make use of the higher resolution. It comes with a refresh rate of 120Hz display. It is almost double the rate for a collection found on most devices, including Samsung.

You will be delighted to know that the device comes with the dust resistance feature in them. The model also has a water-resistant feature in it, coming with the IP68 certification. Both the devices have similar dimensions with 151mm in height and 7.9mm in thickness.

It makes your browsing and games a lot easier and more fun. You can also use it to view your social media account. However, if the resolution and screen size is not big enough, the experience is ruined then and there.

We recommend a large screen and a breathtaking resolution. But we felt that the display on the S21 was splendid. Unfortunately, the S20 came with the old Gorilla Glass 6 & the other model comes with the Gorilla Glass Victus frontage.

We felt that the S20 felt slightly premium compared to the S21. That is because of the soft side designs and an aluminum frame. The Samsung Galaxy S21 smartphone has an excellent strategy. However, it comes with a cheap-looking composite at the rear.

It weighs close to 170grams that is not really heavy. At times, you felt that the S20 itself was heavy at 163grams. The S20 has a more generic appeal to it. The QHD makes the S20 unit a better one.

But the camera module found in the S21 is quite astounding to say. The maker has provided you with an ultrasonic fingerprint sensor. In addition, the S21 model comes with the AMOLED display that works well with the 120Hz refresh rate.

However, the resolution was slightly lesser than the S20 at only FHD+ (1080 x 2400) resolution. But the S21 is able to do well in bright conditions. That is because it works with 1300 nits, and the S20 works with 1200 nits.

The camera specifications are similar. The 64MP lens can help you capture 1.1x zoomed shots. But with the help of the software, they allow you to take eloquent hybrid zoom shots. This is where the S21 comes out on top because of the new hardware.

The design & features, cameras of both the devices were pretty good, but we thought that the S20 was slightly better overall. The design and specifications are everything you would want to put in there.

Samsung Galaxy S20 vs Samsung Galaxy S21: Setup & Performance

The setup & performance of any smartphone is the most crucial element of all. We can vouch for the fact that the models did exceedingly well in that aspect. So let us read and find out how they’re performed.

A notable element in both smartphones is the new split hardware. Most of the global variants of the model use Qualcomm & Snapdragon equivalents, but the rest of the world makes use of the Exynos chips.

The Samsung Galaxy S20 smartphone comes with a good performance. The setup of the model is splendid and easy. All you need to do is switch it on, and you are taken with a few instructions and done in no time.

This is something that is quite admirable with Samsung products. They can begin working in no time (laptop included). It comes with a power of 8GB of RAM as standard. You also have them with 128GB of storage space as standard.

But please do note that only this model has a microSD slot. The UI is excellent, and we found them to be powerful. It is customizable and comes with plenty of features found on it. The models released in the US come with the Snapdragon 865 chip.

The S20 helps things with the 5G technology because of its battery life. Though it is not good enough compared to the S21, it is suitable for working on 5G connectivity. It is much better than the S10 device.

The quick charging works splendidly well on the Samsung smartphone. When you are using the right kind of charger, it can take from 0 to 100% in 60 minutes. But, unfortunately, it comes with a 15W wireless charging too that is not very fast actually speaking.

The Samsung Galaxy S21 smartphone has a phenomenal setup & performance. The main benefit of using the S21 model is that it is much newer. You stand to get an additional year of software support from the maker.

Besides, it comes with the Snapdragon 888 processor that provides you with several enhancements. For example, you can now play games, take photographs, and even work on artificial intelligence.

When you want optimum performance, you can use the Kryo 680 CPU. It provides you with immense power compared to the S20. First, however, you will want to know that the A15 bionic phone from Apple is the quickest.

The S21 is provided with the S pen. We felt that this could be the gamechanger in this review. But unfortunately, the S pen is provided only for the Galaxy Note products, not others. So, of course, you have to get it separately.

You may even need a case to store it separately. But that is the beauty of using this device because you get to work with it. So the feature is exceptionally ideal for those of you searching for using a tablet-like device without having to spend more than $1000.

We must say that the performance was quick and almost on par with the iPads. Therefore, the Samsung Galaxy S20 is a worthy device that one can look at. However, we were not impressed with the fact that it is quite expensive, and the unit does not support all 5G networks.

In terms of practicality, the S21 provided the unit with more juice than its counterpart under most circumstances. You can perform a wide range of activities, including multi-tasking, gaming, and others, with the help of multiple apps using split-screen view.

You may want to think about that before delving into it. In contrast, the S21 did remarkably well, providing you with a breathtaking performance. This feature might make the difference in the end.

Though the S20 is priced cheaper comes with a better camera, the battery specifications on the S21 make it better than the counterpart discussed in here.

The Samsung Galaxy S20 model is priced under $900. It is available at a discount for $618 in the market. The unit was released into the market in 2020 and had been going quite strong. Earlier, it was launched only for the 4G capability.

Now, the current model works with the 5G as well. However, it may not work with all the 5G networks, which is slightly disappointing. On the other hand, it comes with a phenomenal Snapdragon 865 and has IP68 water resistance.

The Samsung Galaxy S21 unit is priced under $800. You can avail of it for a discount of $690. Though it is priced higher than the S20 model, for now, you will want to know that the smartphone was released in the market in 2021.

Samsung Galaxy S20 vs Samsung Galaxy S21: Verdict

We have ended our comparison review between the Samsung Galaxy S20 smartphone and the Samsung Galaxy S21 smartphone. We hope you liked what you read and were able to make your decision.

If you haven’t, then we suggest that you reread the post. Perhaps, you may have missed out on something. The Samsung Galaxy S20 model is a flagship unit from the maker that comes with sublime features that you will find too hard to ignore.

It is easy to hold and use as well. It also comes with a terrific camera. You will want to know that the camera auto mode works amazingly. This is a 5G compatible device and could be a motivation for getting one for yourself.

Though it is not essential, it could be something that could be helpful. You may not be inclined to use the smartphone if you are on a budget. Though it is always nice to have an upgrade to the 5G, the 4G model works quite decently.

Besides, the unit is very expensive, priced under $900. Moreover, if you already own the Galaxy S10, then you may not be drawn towards the impressive upgrades here. The older devices you have will work just fine for a few more years effortlessly without requiring a new one.

The Samsung Galaxy S21 model is another exceptional smartphone to own and use for yourself. Unfortunately, it has similar features to that of the S20, which does not make it very appealing. However, we found it hard to digest the fact that the overall package is incredible.

But you do not get the option of a QHD resolution. When you are looking for a large smartphone with a 6.2” screen, providing tremendous performance, it is a good option. When you own an older device and are on the lookout for a new update, this model could be a worthy replacement.

Usually, when we compare two new devices, it is the latest model that gets the thumbs up. However, it does not have to be the case always. Though the S20 mostly swayed us throughout the post, the new device is better in most segments, apart from the price.

The manufacturer is playing a slightly dangerous game here by rolling certain areas. However, the pricing of the predecessor has been brought down, to up the ante for the new unit. So, we cannot say that the Galaxy S21 is the flagship model for Samsung.

But it is a solid choice with exceptionally built internals, powerful battery, and is a delight to use.
