Battery Performance


The Samsung Galaxy Note 20 is classed as a High Tier Smartphone (between 500-699 EURO), it has an Exynos 990 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 Qualcomm chipset.

The overall Battery Performance Score is now a global score taking calculations from Battery Life, Power Efficiency and Charging Times.

From the Samsung Galaxy Note 20 test results, we have given this Smartphone a ViserMark Battery Performance score of 44. The Battery Performance Label being further from 100 indicates that this is not one of the best-performing phones. It has been ranked in 57th place of the best Battery Performance Smartphones as tested by SmartViser.

BATTERY LIFE - Days of Use

Through the ViserMark test protocol, the Samsung Galaxy Note 20 obtained a Battery Life Score of 1.5 Days of Use.

The average ViserMark Battery Life score of High Tier Smartphones is 1.7 Days of Use. This means that this Battery Life is performing below average, placing the Samsung Galaxy Note 20 lower on the ViserMark Battery Life autonomy ranking.


Test Graphics

Our testing is based on real smartphone usage from 100% battery level down to Power Off. When testing Smartphones, the testing protocol includes common daily life activities, for instance: Calls, Web, Video and Music streaming, Gaming, Social networks, Picture & Video capture and standby.

All testing is performed under strictly controlled test conditions with all activities being executed in a defined order and timeline.

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.


There are a number of power-efficient processors, within today's Smartphones, that are able to cope with the growing number of new applications and can support high-resolution displays without compromising battery life.

Power Efficiency is calculated using Battery Life and Battery Capacity. This is expressed in “Leaves" and reflects a rating between 1 being least and 5 being the most power-efficient.

The Samsung Galaxy Note 20 achieved an overall Power Efficiency Score of 1

  • Smartphone for Power Efficiency: Ranking #74



To conclude, the Samsung Galaxy Note 20 Battery Performance Score achieved was 44 which is lower than most High Tier devices. However, it does offer a full set of premium features and performance for the user.

The Samsung Galaxy Note 20 has the same Battery Score as the Vivo X51 (47) and performs better than the Motorola Moto Edge. But it is behind some of their main competitors’ Smartphones such as the Oppo Find X2 Neo (47), and the OnePlus 8T (51).
