Success Metrics



Samsung S20 Ultra is the most advanced smartphone of S20 series. Available with 2 different high end chipsets, Qualcomm snapdragon 865 or Exynos 990 we have tested here the exynos version. Holding a wide 6,9” screen with 120 Hz refresh rate it is powered by a massive 5000 mAh. Is it enough to give it an acceptable battery life ?

Testing Results

As Samsung, as on other S series mates, give customers choice between several screen settings parameters so they can balance between battery life and performance, but we are not sure that end users will understand all this easily. When performing our ViserMark protocol we have chosen to test FHD+ resolution with 60Hz which is the default one and 120Hz that increases fluidity. Well Samsung set 60 Hz as default, does it mean that 120 Hz will impact too much on battery life ?

S20 Ultra didn’t manage to reach the minimum score to be ranked 2 Days of battery life and it stays in the 1.5 range whatever the selected refresh rate. When refresh rate is set to 120 Hz S20 Ultra will hardly manage to reach 1,5 days without any security margin (Score 157) and things will go better when setting refresh rate to 60 Hz. In this configuration S20 Ultra scores 182 that give 1.5 rating with more margin.

Test Graphic

We can easily notice impact of refresh rate on battery life between 120Hz and 60Hz.



A flagship holding a 5000 mAh sounds in a good position to offer premium user experience without any compromise on battery life. But S20 Ultra battery should juice exynos 990 and 6,9” screen with 120 Hz refresh rate. This leads to a S20 Ultra which doesn’t beat any record on battery life and is even hardly offering acceptable endurance.

ViserMark tests are performed with the strictest protocol in a controlled environment to ensure repetition and consistency powered and automated by SmartViser’s test automation solution viSer. The automation test includes a variety of user actions from calls to social media and periods of standby times.
