Comparison of Galaxy S21 Ultra with iPhone 12 Pro Max; Duel between two flagships Samsung and Apple

In this article, we are going to compare the Galaxy S21 Ultra with the iPhone 12 Pro Max with its technical specifications, display, camera, and the price of the two flagships, iOS and Android.

The Samsung Galaxy S21 Ultra and Apple’s iPhone 12 Pro are two flagship phones with large screens that should be considered one of the most expensive phones on the market. Are you curious to know what are the differences between these two devices, which one is superior to the other and will be a better option to buy?

Samsung has introduced its Galaxy S21 Ultra to compete directly with Apple’s iPhone 12 Pro Max . In the article comparing the Galaxy S21 Ultra with the iPhone 12 Pro Max, we will look at the differences between the screens, cameras, battery size, charging power and processor in these two models, and take a look inside the box of these two phones.


Both phones have very large screens, but on paper the screen size of the S21 Ultra is slightly larger. This difference is only 0.1 inches and is not very significant. Both phones have one of the largest regular (non-foldable) screens on the market.

Frame rate 10 to 120 Hz dynamic 60 Hz
Maximum brightness 1500 nits 1200 nits
Additional features HDR support HDR support

The iPhone’s signature is the top notch of the screen, which hosts a sophisticated Face ID sensor and a selfie camera, while the Galaxy S21 Ultra uses a very small hole in its screen to host the selfie camera. Cutting the top of the iPhone screen does not cause a problem in your daily use, but it can be a little annoying when you want to watch video or play games with your phone. On the other hand, the Galaxy phone has a full-screen display with very narrow bezels around it and a small hole for a selfie camera on it that is invisible.

The Samsung phone has other advantages in terms of display. Its screen resolution is higher to display sharper details that you will notice especially when reading texts. But more importantly, this panel can run at 120 Hz, which is twice the refresh rate of the iPhone model, and this means smoother scrolling compared to the Apple phone. The new Galaxy phone can enable this high refresh rate at maximum QHD resolution, unlike its predecessor. In addition, the S21 Ultra panel itself automatically adjusts the refresh rate to enable the 120Hz rate only when it is really needed. At other times, the refresh rate drops to save battery power.

The Galaxy S21 Ultra is powered by Qualcomm’s newest and most powerful chip, the Snapdragon 888 (for the US version) or the Samsung Exynos 2100 (for the international version). This year, unlike previous years, the performance of the two chips seems to be equal, and in some cases even the Exynos version is superior to the Qualcomm model. On the other hand, the iPhone 12 Pro Max is powered by Apple’s own A14 Bionic chip.

Both manufacturers have used the most advanced technology available to produce their processors. We are talking about 5nm processing technology. The results of the benchmarks of these two phones on the GeekBench 5 platform are as follows. In addition, the Galaxy model comes with an integrated 5G modem, which offers better consumption using 5G.

Geekbench Scores 5 (single core / multi core)

  • Snapdragon version of Galaxy S21 Ultra: 1104/2913
  • Exynos version of Galaxy S21 Ultra: 1088/3475
  • IPhone 12 Pro Max: 1601/4349

In terms of memory, the base model of the S21 Ultra is 128 GB, which is equal to the iPhone. The new Galaxy does not support microSD cards like its rival; So there is no way to upgrade memory separately on both phones.

The Ultra Galaxy S21 takes on a new look and is integrated with a steel frame around the device, while the iPhone 12 Pro Max camera module sits on a square island like the previous generation. The back cover of the two phones is completely different from each other and you can easily distinguish them from the camera module. In addition to the different looks, there are also big differences in the number and technical specifications of the cameras of these two phones.

Main camera 108-megapixel, 24mm f / 1.8 lens with optical image stabilization 12-megapixel, 26mm f / 1.7 lens with Sensor Shift

Fourth camera 10-megapixel, 10x periscope zoom lens (240mm f / 4.9) with optical image stabilization does not have
Additional sensor Laser autofocus LiDAR sensor

On the one hand, the Galaxy phone has two telephoto cameras, while the iPhone has only one. On your Galaxy phone, you will have a long-range periscope lens with 10x zoom capability (compared to the 5x zoom of the Galaxy Note 20 Ultra). Samsung has also used a secondary zoom camera with a 3x shorter zoom range. The combination of the two makes the Galaxy phone a great camera for users who want zoomed photos without loss of quality.


More interestingly, Samsung has used a 24mm lens for its main camera, while the iPhone’s camera lens is 26mm. This may not seem like a big difference, but the result can be seen in photos taken with the main camera.

Both phones use a camera with an ultra-wide (ultra-wide) lens. When focused with this camera, the Galaxy phone can focus very accurately thanks to a laser autofocus system and the problems that existed in the previous generation of ultra-wide camera can not be repeated. The iPhone also has a LiDAR sensor that helps lock the focus on the subject faster in dark environments.

In terms of video, the Korean representative offers 8K video at 30 frames per second, while the Apple phone can not shoot beyond 4K; However, it has the Dolby HDR standard for richer colors. With 8K resolution, you can record clearer content, while the iPhone HDR option allows you to access higher dynamic range. So both phones have a unique feature.

Battery life and charging speed

  • 5000 mAh battery S21 Ultra vs. 3687 mAh iPhone 12 Pro Max
  • Faster charging on Samsung phones

And in the final part of comparing the Galaxy S21 Ultra with the iPhone 12 Pro Max, we draw your attention to the difference in the battery capacity of these two phones. Android phones typically use larger batteries than iPhones, and the S21 Ultra is no exception. The phone is powered by a 5000 mAh battery, while the battery on the iPhone is 3687 mAh. This means that the battery capacity of the Galaxy is about 50% higher. But you should not expect this capacity to directly lead to 50% more charge and be able to beat the Galaxy S21 Ultra in this part of the Apple phone.

But in terms of charging speed, the S21 Ultra wins . While the iPhone 12 Pro Max supports a maximum charging speed of 20 watts, the charging speed on the Galaxy is 25 watts. It was also the first iPhone in the world to be released without a charger adapter. And now Samsung, following in the footsteps of its rival, has removed the charging adapter from the box of its phone.

Both models support wireless charging at up to 15 watts via a compatible charger. Here, the iPhone uses a new technology called MagSafe that magnetically attaches the phone to wireless chargers and other special accessories. But on the other hand, the Samsung phone has reverse wireless charging, which allows you to use your phone as a wireless power bank and charge your other devices such as the Galaxy Buds Pro earphone.


Circumstances caused Samsung to reduce the price of its flagships this year. In 2020, the S20 Ultra will be priced at $ 1,400, while the base price of the new generation is $ 1,200. However, it is still $ 200 more expensive than the iPhone 12 Pro Max.

128 GB $ 1,200 $ 1,100
256 GB $ 1250 $ 1,200
512 GB 1380 dollars $ 1400
