All you need to know about the Samsung S23 smartphone.


Samsung has recently introduced another smartphone series to the Galaxy range. The Samsung Galaxy S23 may not look different from the previous Galaxy S22, but it delivers good battery performance and functionality with some notable upgrades.

The latest Samsung S23 Series comprises the Galaxy S23, S23 Plus and S23 Ultra. ViserMark's first review of this series is the Samsung Galaxy S23, the smallest in battery capacity and display size and less expensive than the other two smartphones. We will test the remaining series and deliver the battery performance results soon.

Entering the Flagship/Pro Tier (€700+), the Samsung Galaxy S23 joins several other devices in this high-end category based on similarly priced smartphones. All the other Galaxy S23 series of smartphones also compete in this tier.

The Samsung Galaxy S23 is a highly advanced smartphone with a user-friendly interface that makes it very easy to use. It has a sleek, modern design with a large 6.10" Dynamic AMOLED display with a high resolution of 2340 x 1080. The screen has a high refresh rate of 120Hz, providing a smoother visual experience when scrolling through apps and websites.

This mobile phone features a glass front and back with a metal frame, which gives a premium look and feel and is protected by Corning Gorilla Glass Victus, designed to withstand drops and scratches. Having an HDR10+ certification, the display provides a clear and sharp display with an impressive 91.3% screen-to-body ratio, providing an immersive viewing experience.

The camera set-up has improved with a fresher design than the Galaxy S22. One new feature is the under-display selfie camera hidden beneath the screen. This allows for a seamless and uninterrupted display without a visible camera cutout. Users can also enjoy a refined Nightography camera to capture high-quality photos and videos easily. This design can also be incorporated into the Galaxy S23 Plus and Galaxy S23 Ultra designs.

With a surprisingly smaller battery capacity than the Samsung Galaxy S23+ and Ultra, the S23 offers a long-lasting battery performance to ensure you stay connected.

The Samsung Galaxy S23 is available in "fresh new colours" such as Lavender, Cream, Green and Phantom Black. Samsung has also ensured that this mobile phone meets the Standards for Sustainability for Mobile Phones and has been certified to PAS2050, an internationally recognised standard. The Galaxy S23 is made from recycled glass and PET film, and each phone is tucked into a box of recycled paper and paper-based protective film.

A USB-C cable and a SIM ejector tool are shipped with the Samsung Galaxy S23. However, the case or screen protector is omitted, so users of this smartphone may wish to purchase these items separately for added protection.

Smartphone Battery Performance Score

and Battery Performance Results

We have designed and developed Battery Performance Labels to help Smartphone users.

Translated into the ViserMark Labels, below are the battery performance test results for the Samsung Galaxy S23.

Our experts are asked to test more than 100 Smartphones every year. As an independent mobile phone testing environment, SmartViser measures key areas of user experience.

More details can be found on how we perform our smartphone testing here.


Look at the review by ViserMark based on the results during testing. You can find the full results of our battery performance testing below:

Smartphone Battery Performance Overall Score:

The Battery Performance Label shows a score between 0 and 100. It reflects the performance based on independent, repeatable, and rigorous testing.

ViserMark Battery Performance Label
Samsung Galaxy S23 Smartphone Battery Performance Score

Using various testing criteria, measured using real-life scenarios and live networks, results collated with calculations from Battery Life, Power Efficiency and Charging results that amount to the total score.

Within the ViserMark Flagship/Pro Tier (€700+), the Samsung Galaxy S23 competes closely with the Google Pixel 6 and a predecessor, the Samsung Galaxy S22 Plus, when comparing battery performance shown in the chart below.

Comparison of Smartphones in the Flaghship/Pro Tier

In our recent smartphone review, the Samsung Galaxy S23 achieved 41 out of 100, compared to last year's Samsung S22 Plus; just one point more! By only a small margin, the

Google Pixel 6 obtained a slightly better overall battery performance of 42 out of 100.

Despite both Samsung devices having the same battery capacity 4500mAh, the Samsung Galaxy S23 benefitted from some notable upgrades to performance, enhancing user experience. The Google Pixel 6, with a 4600mAh battery capacity, is only fractionally bigger than both Samsung devices. The Google Pixel 6 and 6 Pro were the first smartphones to be released equipped with Android 12, the new Google interface.

Other smartphone battery performance results can be seen in the Flagship/Pro Tier Ranking table.


Battery Life

Battery Life - How long will this Smartphone battery last?

The Battery Life ViserMark Label displays the “Days-of-Use” in both actual days and provides accurate information in hours. It reflects the usage of a smartphone from a full charge.

Samsung Galaxy S23 Smartphone Battery Life Results

Samsung claims that the Galaxy S23 has up to roughly 22 hours of video playback and is more than adequate to keep you connected without running out of power. During our testing, the Galaxy S23 provided 36 hours of good battery performance and could match other smartphones with 1.5 days of usage. When we tested the Samsung S22 Plus and the Google Pixel 6, only 3 hours separated all three devices. As shown in the chart below.

Comparison of Smartphones in the Flaghship/Pro Tier

Being powered by a Snapdragon processor, the Samsung Galaxy S23 offers fast performance, particularly better for gaming and video streaming, and a good user experience when running multiple applications simultaneously.

The Samsung Galaxy S23 has an adaptive refresh rate between 48Hz to 120Hz. It enables the display's responsiveness during gaming. With 1,750 nits of brightness, the display is excellent indoors and outdoors, and the Advanced Vision Booster feature automatically optimises colour accuracy and contrast in certain conditions. There is a Dark Mode feature that helps to save battery life.

Samsung Galaxy S23 Smartphone Charging Time Results

During our independent testing of charging times, the Samsung Galaxy S23 takes over 1 hour and 59 minutes for a full 0-100% charge with 25W wired charging. Samsung says the Galaxy S23 supports “Super fast charging,” while the Galaxy S23 Plus and the Galaxy S23 Ultra support “Super fast charging 2.0.”

As you can see in the chart below, the Galaxy S22 Plus took over 2 hours to charge its 4500 mAh battery, and the Google Pixel 6 took 1 hour and 47 minutes for a full charge on its slightly higher battery capacity of 4600 mAh.

Comparison of Smartphones in the Flaghship/Pro Tier

Samsung continues to improve charging performance, as seen with the S23 series. However, it would be great to see a 45W charging speed on the Samsung Galaxy S23.
