Success Metrics



S models from Samsung are one of the most successful and always awaited smartphone series. Within 2020 S20 range S20+ is a very good trade off as it keeps a compact format while integrating a 4500 mAh high capacity battery. Flagship competition has never been so tough for S series and end users have got high expectation on battery life as this is one key area where customers are unlikely ready to compromise.

Of course this new S20+ model is bringing a full set of innovation and especially around display which is now offering 120 Hz refresh rate. To stay in the race of performance brand new chipsets are integrated as well and as usual Samsung is duplicating proposal depending on markets: Qualcomm 865 and Exynos 990. For this test we have selected Qualcomm 865 to compare with rivals equipped with same processor. We are preparing a dedicate test to compare 2 identical devices from Samsung but powered by different chipset. But let’s how the selected S20+ configuration behaves on viSerMark protocol, with a 4500 mAh battery we have high expectations.

Testing Results

First of all when testing such kind of devices with multiple parameters that have a direct impact on battery life you need to make some choices: which resolution should we use? Which refresh rate should be select? One advantage of S20+ is to give end user a wide range of choices: resolution from HD+ to Quad HD+, 60 or 120 Hz refresh rate. No other phone allows you to balance as much as S20+ between battery life and screen fluidity. This is a true good point, however we think that most end users will not too much in those settings details and this keeps interesting for tech users.

At ViserMark we use default resolution and we always test the different refresh rates settings as this is a key marketing item. When we started the S20+ we noticed that default refresh rate was set to 60Hz by default. It sounds that Samsung is not very confident in getting a good battery life while using 120 Hz refresh rate. We also noticed that battery saver mode is rather aggressive while reaching 5% level.

When testing with FHD+/60Hz configuration S20+ is able to reach 2 days ViserMark score, without any merging ending second day with 4% remaining levels, so in the range of battery saver activation. This is minimum that we were expecting from a flagship.

When turning on 120 Hz refresh rate then unsurprisingly achieves a lower score, 120 Hz refresh rate will not dramatically drive down battery life but S20+ fails to achieve 2 days ViserMark score in this configuration. End Users that would try changing this setting will undoubtedly notice the difference in battery life performance and will surely not feel very comfortable if trying to run a full second day without charging.

Test Graphic

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



To conclude, Samsung S20+ offers a full set of premium features and performance. However on Battery Life side we were expecting more from its 4500 mAh battery and overall viSerMark score is good but not excellent.

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.
