Battery Performance


The Xiaomi Poco F3 is classed as a mid-tier device (between 200 and 500 EURO) in the ViserMark list. The fast Snapdragon 870 chipset is inside the phone assuring 5G connectivity and delivering more than enough power to match the user expectations.

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

From the Xiaomi Poco F3 test results, we have given this Smartphone a ViserMark Battery Performance Score of 49. The Battery Performance Label being further from 100 indicates that this is not one of the best-performing phones. It has been ranked in 34th place of the best Battery Performance Smartphones as tested by SmartViser.


Testing Results

BATTERY LIFE - Days of Use

Through the ViserMark testing protocol, the Xiaomi Poco F3 battery lasted almost 50 hours with a 60 Hz refreshing rate and 48 hours with 120 Hz obtaining a Battery Life score of 2 Days of Use.

The average ViserMark Battery Life score of a Mid Tier Smartphone is 1.9 Days of Use. Being ranked 41, this score places the Xiaomi Poco F3 slightly above average within its tier. However, it is still behind some of its main competitors, one being the Realme 8 Pro.


CHARGING TIME - Hours and Minutes

To reach the full 100% the Charging Time was 1 hour and 3 minutes. The average Charging Time is 1:39 for a Smartphone within the ViserMark Mid Tier.

  • Best Smartphone for Charging Times: Ranking #13

  • One of the Top 5 Mid Tier Smartphones with the Best Charging Times


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.

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.

Xiaomi Poco F3 achieved an overall Power Efficiency Score of 1.5

  • Best Smartphone for Power Efficiency: Ranking #57



To conclude, the Xiaomi Poco F3 autonomy sits in the middle of most devices in its price range, offering 2 days of autonomy through the ViserMark Test Protocol. To compare it with other Mid Tier Smartphones, its battery does not perform as well, for example, the Samsung View 5 Plus with a performance score of 68 and the Xiaomi Redmi 9T 5G having a score of 55. There is still some work is to be done by the Chinese manufacturer to reach the Top of ViserMark ranking and deliver 4 days of autonomy.


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.
