Continue reading to learn the differences between the upcoming Samsung S21 and the Apple iPhone 12.


iPhone 12
The base model iPhone 12 comes with a 6.1 OLED display at 2532×1170 pixels. This comes in at about 460 pixels per inch. The Pro model of the iPhone 12 is the same size as the base model. The iPhone 12 mini has a 5.4 inch screen at a slightly lower resolution of 2340×1080, coming in at 476 pixels per inch.

All models of the iPhone 12 come with an HDR display and haptic touch. The displays are also capable of 625 nits when it comes to brightness.

A new feature for the iPhone 12 is the ceramic shield. This is a new type of glass, and Apple claims it is the toughest smart phone glass ever. This means that the iPhone 12 is the most drop resistant iPhone ever created. If you’re known to frequently drop your phone, you’ll be happy to know that the iPhone 12 can resist drop after drop without cracking.

Samsung S21
The S21 comes in 3 sizes. The standard S21 comes with a 6.2 inch AMOLED display, coming in at 2400×1080 pixels, making it 421 pixels per inch. The Plus model is a 6.7 inch screen with the same resolution. The large Ultra model is 6.8 inches and has a 3,200×1440 resolution, making it 515 pixels per inch.

The S21 comes with Gorilla Glass Victus, the newest drop resistant glass from Gorilla Glass.

Where Samsung’s S21 display triumphs over iPhone is refresh rate. The Samsung S21 comes with a refresh rate of 120 hertz; iPhone 12 is still using a 60 hertz display.


For many people the camera means everything when it comes to their smart phone. Consumers want crystal clear photo that can be taken at a moment’s notice.

iPhone 12
The iPhone 12 comes with a dual 12 MP camera system on the back, including an ultra wide camera. With the iPhone camera, 2x optical zoom and 5x digital zoom is possible. iPhone is known for innovating smart phone cameras with nearly every release, and this year is no different. The iPhone 12 comes with, advanced red-eye correction, auto image stabilization, geotagging, panorama, night mode, and deep fusion.

The iPhone 12’s biggest camera improvements this year is most noticeable when recording video. The iPhone 12’s camera is capable of recording in 30 frame per second with HDR enabled, meaning less glare in your videos and generally, clearer video image. The iPhone 12 alsol supports slow-mo video support at 1080p with 120 or 240 frames per second. It is also possible to take photos while video is being recorded, meaning you can capture the same moments in video and in picture formats.

Samsung S21
The S21 comes with a plethora of features for its main camera. The primary lens is 108 MP. It also has a 12 MP ultrawide lens. The selfie camera on the front of the device can capture photos in 40 MP.

The rear cameras are capable of recording video at 8k resolution at 24 fps, 4k resolution at up to 60 fps, or 720 at 960 fps, making it one of the most diverse cameras on the market today. The front camera can record video at 4k or 1080p.


The CPU is the brain of the smart phone. It handles all the calculations necessary to make sure the phone functions and operations in a responsive way. Smartphones typically use a SoC(system on a chip) instead of a traditional CPU. This means that almost every component needed to run a computer is jammed into the CPU in smart phones.

iPhone 12
Apple focused their marketing on the A14 SoC this year, and it was for good reason. The A14 is the fastest, most powerful smartphone CPU on the market right now. Apple has made incredible progress on their CPU manufacturing in the last few years, even ditching Intel to create their own silicon chips for their laptops. The A14 SoC greatly foreshadows what to expect from Apple in the future.

The A14 SoC comes with 6 cores total. 2 of the cores are big cores, capable of heavy loads. The other 4 are smaller cores, used to handle less heavy loads while the main cores are doing more important tasks. The SoC from Apple also clocks in at 2.99 GHZ.

The A14 chip supports Wi-Fi 6, the newest, fastest, protocol to handle Wi-Fi signal.

The CPU in the S21 is the Snapdragon 888, Qualcomm’s newest high-end mobile SoC. The 888 has a bigger core count than Apple’s A14; however, it has a slower clock speed coming in at 2.84 GHz.

Qualcomm wasn’t able to beat Apple’s A14 chip this year, but that doesn’t mean it’s not a capable SoC.

The Snapdragon 888 also comes with Wi-Fi 6 built in, meaning your Wi-Fi connection will be faster than ever.

Battery and Charging Speed

Charging speed is another big sale for consumers. Users want a phone that maintains its charge and charges back snappy. Read below to find out who edges out when it comes to battery performance.

iPhone 12
iPhone has finally made the decision to move to USB-C(kind of.) This means that the iPhone 12 charges faster than any previous iPhone model. The iPhone 12 averages about 8 and a half hours of use on a singal charge. The 12 Pro lasts a little longer, coming in at about 9 hours. The iPhone 12 Pro Max model performs way better, almost lasting 11 hours of use. If battery life is what you’re going after, then the iPhone 12 Pro Max is definitely what you’ll want.

There are lots of variants when it comes to charging speed. The type of adapter you use, the cable, and whether you are wirelessly charging or charging with a cable all determine how fast your phone will reach 100%. Under the best conditions, the iPhone 12 takes about an hour and a half to reach full charge from 0 percent.

There is not as much data about the battery of the S21 as there is about the iPhone 12 due to it not being released yet. However, what we do know is the size of the battery. The base model S21 comes with a 4,000-mAh battery. The Plus has a 4,800-mAH battery, and the Ultra comes with a 5,000-mAh battery.

A phone case is the best way to make sure your phone remains in one piece. The S21’s gorilla glass and the iPhone’s ceramic shield mean very little if you don’t have a good phone case to go with it. Both the S21 and iPhone 12 have drop resistant screens; however, nothing will protect your device like a good case. Make sure to pick one up no matter which phone you decide to go with. CASEKOO has released protective clear case both for Samsung and iPhone 12 series, which not only can show out the original color of the device, but also can protect the phone from dropping and scratches.
