The Galaxy S8 comes with a curved 5.8-inch Infinity Display with Quad HD+ (2960 x 1440) resolution and an aspect ratio of 18.5:9. The new aspect ratio makes the display taller than usual but it is better suited for multi-window multitasking.

The Galaxy S8 comes with either Samsung’s own Exynos 8895 chipset or Qualcomm’s Snapdragon 835 chipset. Both chipsets are based on Samsung’s 10nm LPE fabrication process that should make them more power efficient than other 14nm based chipsets.

The Galaxy S7 and S7 edge featured Samsung’s own Exynos 8890 chipset or Qualcomm’s Snapdragon 820 chip. Both chipsets are based on the 14nm fabrication process.

Storage & RAM

The Galaxy S8 and S8+ both feature 64GB of NAND storage based on the UFS 2.1 interface. They also come with 4GB of RAM and a microSD card slot.

The Galaxy S8 features the same camera setup as the Galaxy S7. This means we are looking at a 12MP f/1.7 shooter with Dual Pixel and OIS. However, like the Google Pixel, the Galaxy S8 now takes three pictures in quick succession and combines them into one for better low-light imaging performance.

At the front, the Galaxy S8 features an 8MP f/1.7 shooter with autofocus, while the Galaxy S7 features a 5MP f/1.7 selfie shooter.


The Samsung Galaxy S8 and Galaxy S8+ are the first phones to feature gigabit LTE Cat.16 modem. They are also the first phones in the market to launch with Bluetooth 5.0. The Galaxy S8 also features a USB-C port.

The Galaxy S7 and S7 edge only support LTE Cat.9 speeds, and they shipped with Bluetooth 4.2 out of the box. The Galaxy S7 and S7 edge feature a microUSB port.


The Samsung Galaxy S8 comes with a 3000mAh battery, while the Galaxy S8 Plus features a 3500mAh battery. Both batteries will be able to hold up to 95 percent of their capacity after two years.

The Galaxy S7 also featured a 3000mAh battery, while the Galaxy S7 edge came with a slightly larger 3600mAh battery.

All the four phones support fast charging, both wired and wireless.

Biometric Authentication

The Galaxy S8 features three different types of biometric authentication: iris, fingerprint, and face.

The Galaxy S7, in comparison, only features fingerprint authentication.

IP Certification

All the four handsets — Galaxy S7, S7 edge, S8, S8+ — feature an IP68 certification that makes them dust and water-resistant in up to 1.5m of fresh water for up to 30mins.

Samsung Pay

All four handsets also support Samsung Pay.

New Features

The Galaxy S8 comes with two new features which are missing on the Galaxy S7: Bixby and DeX. The former is Samsung’s new AI-powered virtual assistant that features Bixby Vision and is contextually aware. As for DeX, its a docking accessory for the Galaxy S8 that turns it into a full-blown Android-powered PC replacement.

So, do you think the Galaxy S8 and S8+ are a huge upgrade over the Galaxy S7 and S7 edge? While the larger displays and other key improvements definitely make Samsung’s latest flagship a winner, their battery capacity has me worried. A 3000mAh battery for a phone with a 5.8-inch QHD+ display sounds like a combination that will struggle to make it through the day.
