Mobile phones have evolved beyond imagination in today’s age. What used to be a small device capable of only making calls and texts can now perform tasks that a computer could. Smartphones are basically mini supercomputers that can fit in your pockets. While the pros and cons of these advancements are often debated, their impact on our lives can not be denied. Smartphones are still continuously evolving and the number of choices is increasing too. There are too many brands that offer different kinds of technologies and features. Every year we see hundreds of new smartphones and all of them sound amazing. The increasing advancement and number of smartphones have made it harder to choose the right device. However, there are certain brands that are always at the top of the table. Two of these brands are Apple and Samsung.

Samsung Vs Apple

Samsung and Apple are two of the in existence and it has been like that for a long time. One of the biggest rivalries in smartphones and smart gadgets, Samsung and Apple have been going at war for years constantly. They have a similar range of products, price segments, and higher-end devices. These two are prominent figures and adversaries in the premium smartphone segment especially. They both have made new additions to that segment this year in form of Samsung Galaxy S20 Ultra and iPhone 12. Here’s a complete comparison of the two.


A processor is the brainpower of every smartphone. A processor decides how efficient and fast a smartphone is at handling different tasks. How a smartphone handles games, apps, and multitasking, depends on the processor as well.

Samsung S20 Ultra features the powerful Qualcomm Snapdragon 865 in the US version but their own Exynos 990 processor in other regions. It is accompanied by an octa-core CPU setup. The US version features Adreno 650 for GPU and the global version has Mali-G77 MP11 GPU.

The iPhone 12 has Apple’s own A14 Bionic chipset for all the models as well as a Hexa-core CPU. For graphics, Apple uses its own 4-core Apple GPU here.

The difference of processors in the global and the US versions are bound to irk the fans. The reason for the move is unknown but it surely acts as a negative in S20’s score. iPhone provides the same features for all versions which gets a big thumbs up

From a performance point of view, both smartphones perform great. Apple’s A14 however has an edge over both Snapdragon 865 and Exynos 990.


Apple has always been consistently superior with its cameras and the iPhone 12 is no different.

iPhone 12 has a dual-camera setup on the back.

It includes; a 12 MP wide camera of f/1.6 aperture and a 12 MP ultrawide camera of f/2.4 aperture. It can record videos at a 4K resolution at a 60 fps rate.

The front too features a dual-camera setup. However, one of them is just a depth and biometric sensor. The primary camera is a 12 MP camera of an f/2.2 aperture. It is also capable of taking 4K videos at 60fps.

Samsung S20 Ultra takes away the cake from Apple in the camera department this time.

On the back, there are four cameras. It includes;

A 108 MP camera with f/1.8 aperture, a 48 MP telescopic camera with 4x optical zoom and 10x hybrid zoom, a 12 MP ultrawide camera, and a 0.3 MP depth sensor.

It can record videos in 8K resolution at 24fps and 4K resolution at 60fps.

On the front, there is a huge 40 MP selfie camera that can record 4K videos at 60fps

Design and Build

Apple iPhone 12 has a sandwich frame. The front is covered in Gorilla Glass and so is the back. An aluminum frame is sandwiched between these layers of glasses. So how, it is recommended to and the major role of these covers is to prevent the smartphone from normal wear-tear. The dimensions of this device are 5.78 x 2.81 x 0.29 inches. It has a more compact form. It weighs 164 grams. It is available in five colors; black, white, red, green, and blue.

The Galaxy S20 Ultra has a bigger build than iPhone 12. Its dimensions are 6.57 x 2.99 x 0.35 inches. It weighs more than the iPhone too, weighing at 222 grams. It has a similar sandwich frame of aluminum in between a front and rear Gorilla Glass 6 covering. It is available in three colors; cosmic grey, cosmic white, and cosmic black.

Displays of both Samsung and Apple devices are always of superior quality. That hasn’t changed with these two devices and has only improved more.

Samsung Galaxy S20 Ultra has a dynamic AMOLED 2X display that is 6.9″ big. The screen resolution is 1440 x 3200 pixels with an amazing 511 PPI density. That combined with a 120Hz refresh rate and HDR10+ support makes everything visually better. The aspect ratio is 20:9 along with an 89.9% screen-to-body ratio. Samsung Galaxy S20 Ultra is a powerpack monster with smooth display and sleek designs and the thing that adds a charm to this beast is, the wide range of that are available in the market.

The iPhone 12 features a 6.1″ big Super Retina XDR OLED screen with HDR10 support. The resolution here is 1170 x 2532 pixels with a slightly lower 460 PPI density. There is Gorilla Glass 5 protection along with an oleophobic coating.

Both the devices have amazing displays but the S20 Ultra has a slight edge over the iPhone 12.

Operating System and UI

Nobody needs to be taught this but just to state a fact, Samsung Galaxy S20 Ultra works on Android, and the iPhone 12 works on iOs. S20 comes with Android 10 out-of-the-box and an Android 11 update is promised in nearest future. iPhone 12 too comes with a support for the latest 14.1 version of the iOs. Both the operating systems have their own features and unique qualities. The same is the case with their UIs. S20 Ultra uses Samsung’s own OneUI 2.5 and the iPhone 12 works on the iOs 12 GUI.

RAM and Storage

Samsung Galaxy S20 Ultra has two options for RAM 12 GB and 16 GB. It is paired with three storage options to make up three variant models. That is 128 GB storage & 12 GB RAM, 256 GB storage & 12 GB RAM and 512 GB storage & 16 GB RAM. The storage can be further extended up to 1000 GB.

You get only a single RAM option of 4 GB in the iPhone 12 which is slightly disappointing. There is no option for 512 GB storage either. Neither you can expand the storage with an SD card.

There are three model variants; 64GB & 4GB RAM, 128GB & 4GB RAM, 256GB & 4GB RAM.


Battery life has to be one of the most important aspects of any smartphone. Battery specs of smartphones these days are getting better and better as well. S20 Ultra is a perfect example of that as it promises a 25 hours battery life.

That is provided by a 5000 mAh Li-Po battery. 15W Qi wireless charging is supported and so is 45W fast charging. Also, a 4.5W reverse charging is available. USB Type-C is used for charging.

iPhone 12 has a considerably smaller 2815 mAh Li-Ion battery. It supports 20W fast charging and 15W Qi wireless charging. iPhone 12 too advertises a standby time of up to 17 hours straight. For charging, there is as usual a lightning port.

Apple devices are more demanding in maintenance and repair expenses.
