Success Metrics


Galaxy models from Samsung are one of the most successful and always awaited Smartphone series. The Galaxy Note is dedicated to people who want more than just a Smartphone.

The Samsung Galaxy Note20 has a big format while integrating only a 4300 mAh high capacity battery. As a flagship product it needs to meet the high expectation on battery life performance, as this is one key area of focus for users.

The Exynos 990 is the chipset that has been selected by Samsung for this particular Smartphone. This presents an ideal opportunity to see if this chipset has a better battery consumption when compared to the Qualcom chipset. So let’s see how the selected Galaxy Note20 configuration behaves during testing using the ViserMark Protocol.

Testing Results

When testing the Galaxy Note20 Smartphone, we found the battery life can last just over 1.5 days based on the ViserMark score. This is not the minimum that we were expecting from this kind of flagship. The choice of the Exynos 990 chipset has a negative impact on the battery consumption compared to competitors. Also, the choice of a 4300 mAh battery capacity is not a beneficial choice and does not give to users the best experience in terms of autonomy.

Test Graphics

Looking at the graph below, we can easily identify the impact of battery life. It is interesting that we can repeat the same battery life consumption behaviour on each test run.


To conclude, the Samsung Galaxy Note20 offers a full set of premium features and performance. However, it's battery life performance does not offer an acceptable result for a flagship product and we recommend increasing the battery capacity for next Samsung flagship.
