Success Metrics


Since very first Nexus phones Google is introducing every year its vision of the essential while efficient smartphone: sleek design, compact size, powerful chipset, best in class picture processing. Available since October 2019 Pixel 4XL will be replaced in the coming weeks with a full new set of devices. We anyway wanted to rank it in front of flagships to see if google vision of efficiency is also able to match with end users expectations in terms of battery life to be the perfect daily mate. Indeed, 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 competition.

Testing Results

Although Pixel 4 XL is not getting an impressive battery specs should help him to achieve a good score: 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. 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 Pixel 4 XL managed to achieve 1.5 days rating with almost similar execution time and score. We were not expecting Pixel 4 XL at this performance level and Pixel 4 XL platform (Hardware and OS) seems very efficient and will be able to deliver a good battery life experience.

Test Graphics

As refresh rate is adaptive impact of switching 90 Auto on will not impact too much battery life while increasing fluidity.


We were not expecting Pixel 4 XL at this performance level. With a 3700 mAh battery capacity it is able to maintain activity for 1.5 days, which is a true positive news for the ones enjoying simplicity and efficiency.
