Google Pixel 4 XL - Battery Performance Score

Updated: Mar 30, 2022


Battery Capacity mAh: 3700


Smartphone Battery Performance: Ranking #49

With a Battery Performance Score close to 50 this Smartphone is positioned halfway in the Flagship/ProTier Ranking Table.


Battery Performance Testing and Review - September 2021



Since the very first Nexus phones, every year Google is introducing its vision of the essential while efficient smartphone: sleek design, compact size, powerful chipset, best in class picture processing. Available since October 2019 Pixel 4 XL will be replaced with a full new set of Smartphones.

The Pixel 4 XL is not a jewel as other flagships, its main asset remains its ease of use, and in order to maintain acceptable weight Pixel devices are usually integrating lighter capacity batteries. With 3700 mAh let’s see where Pixel 4 XL can stand in front of the competition.

The screen size remains in a rather compact format and integrates a 90 Hz maxi adaptative refresh rate, animated by powerful but efficient Snapdragon 855 and pure android.

Battery Performance


The Google Pixel 4XL is classed as a Flagship/Pro Tier (700 Euro +). It has a refresh rate that is adaptive, so switching 90 Auto on will not impact too much battery life while increasing fluidity.

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

From the Goole Pixel 4 XL test results, we have given this Smartphone a ViserMark Battery Performance Score of 46. The Battery Performance Label being further from 100 indicates that this is not one of the best-performing phones. It has been ranked in 49th place of the best Battery Performance Smartphones as tested by SmartViser.


Testing Results

BATTERY LIFE - Days of Use

Through the ViserMark test protocol, the Google Pixel 4XL obtained a Battery Life Score of 1.5 Days of Use.

The average ViserMark Battery Life score of Flashship/Pro Tier Smartphones is 1.6 Days of Use. This means that this Battery Life is performing below average, placing the Google Pixel 4 XL 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.

We have been positively surprised by Pixel 4 XL performance. We have been using default QHD+ resolution changing only refresh rate from 60 Hz to 90 Hz Auto. In the two different configurations, the Google Pixel 4 XL managed to achieve a Battery Life of 1.5 Days of Use.

We were not expecting Pixel 4 XL at this performance level and the Pixel 4 XL platform (Hardware and OS) seems very efficient and will be able to deliver a good battery life experience.


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 Google Pixel 4 XL achieved an overall Power Efficiency Score of 1.5

  • Smartphone for Power Efficiency: Ranking #46



To conclude, the Google Pixel 4 XL Battery Performance Score achieved was 46 which is slightly lower than other Flagship/Pro Tier Smartphones. However, we were not expecting Pixel 4 XL at this performance level regardless as it only has a 3700 mAh battery capacity. Meaning this phone is great for end-users who enjoy simplicity and efficiency.

The Google Pixel 4 XL performs better than the Samsung S20 Ultra (42) despite its small battery size. But it is behind some of the other main competitors such as the Xiaomi Mi 10 Pro (50) and the Apple iPhone (57).


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.
