Battery Performance
Introduction
With a price of around 400 EURO, the Samsung Galaxy M51 is a Mid-Tier smartphone in the ViserMark ranking (Smartphones priced between 200-500 EURO). The Qualcomm SMD 730G Snapdragon 730G orchestrate the smartphone.
A 7000mAh battery powers the M51 to assure high autonomy. Compared with other Mid-tier devices, a higher refresh rate is a missing feature in the M51 that allows 60 Hz.
The overall Battery Performance Score is now a global score taking calculations from Battery Life, Power Efficiency and Charging Times.
We have given this Smartphone a ViserMark score of 62 based on the results. The Battery Performance Label, being nearer 100, indicates that it is one of the best-performing and has been ranked 5th among the best Battery Performance Smartphones tested by SmartViser. The M51 additionally stands on the podium of Mid-Tier device's battery performance, ranking just behind the Wiko View 5 Plus.
Testing Results
BATTERY LIFE - Days of Use
The Samsung Galaxy M51 reached 82 hours of autonomy through the ViserMark test protocol with a 60 Hz refreshing rate, obtaining a Battery Life score of 3.5 Days of Use.
A Mid Tier device's average Day of Use ViserMark score is “2” Days. The M51 score places the Smartphone at the Top of the ViserMark Mid-Tier ranking regarding autonomy, sharing the first position with the Wiko View 5 plus.
CHARGING TIME - Hours and Minutes
The charging time to 100% was one hour and forty-seven minutes, with the 25W fast charge option included. This value is even 8 minutes slower than the 115 minutes advertised by Samsung.
The average Charging Time is 1:36 for a Smartphone within the ViserMark Mid-Tier. This score places the M51 in the middle of the charging time ranking, and a higher power charger could be an option to get a faster charge, considering the device’s battery size.
Currently, in the middle of the Smartphones with the Best Charging Times
Test Graphics
Our testing is based on smartphone usage from 100% battery level down to Power Off. When testing Smartphones, the testing protocol includes everyday life activities, for instance, Calls, Web, Video and Music streaming, Gaming, Social networks, Picture and video capture and standby.
All testing is performed under strictly controlled test conditions and executed in a defined order and timeline.
