Google Pixel 8 Pro DxOMark battery analysis shows device pales in comparison to Galaxy S23 Ultra & iPhone 15 Pro Max

If you’re into tech, you’ve probably heard of DxOMark, a company that tests and compares various smartphone features like cameras, batteries, and speakers. They recently tested out the battery of Pixel 8, which unfortunately failed to meet expectations. Now, DxOMark has published the battery analysis report for the Pixel 8 Pro.

For those unaware, the Pixel 8 Pro boasts a battery capacity of 5,050 mAh and supports fast charging of up to 30W. So, here’s the battery analysis report of Pixel 8 Pro compared to Galaxy S23 Ultra and iPhone 15 Pro Max. It includes three aspects: autonomy, charging, and efficiency.

The autonomy score is based on three aspects: Home/office use, on-the-go use, and calibrated use cases. The DxOMark testing showed that the Pixel 8 Pro excelled in some scenarios but didn’t match its predecessor or other phones in some respects.

The Google Pixel 8 Pro achieved nearly 55 hours of autonomy. Although it showed better performance in gaming and streaming video, its performance in other individual tests fell slightly below average. Additionally, the autonomy score did not meet expectations specifically while listening to music. You can check out the complete autonomy test below. 

When a smartphone has a low autonomy score, its charging capability becomes vital. If the battery drains quickly, the device should ideally have a faster charging ability to compensate. DxOMark’s charging test includes two sub-tests: Full charge and quick boost.

The Pixel 8 Pro takes about 1 hour and 40 minutes to fully charge with a wired charger, 30 minutes faster than its predecessor. However, it’s slower compared to other phones. Wireless charging takes around 2 hours and 34 minutes, which is also slightly longer than average.

The DxOMark power efficiency score is made up of two sub-scores: Charge up and discharge rate. These aspects are determined through calibrated tests and the charging behavior analysis.

The Pixel 8 Pro exhibited low charge efficiency in both wired and wireless charging scenarios. Moreover, the chargers’ residual consumption was consistent whether the device was fully charged or plugged in. In terms of discharge currents, the Pixel 8 Pro has higher consumption than the average, particularly when streaming music and browsing social apps on-the-go.

The autonomy score for the Google Pixel 8 Pro reached 113, falling notably short when compared to the scores of 148 achieved by the Galaxy S23 Ultra and iPhone 15 Pro Max. While both the Pixel 8 Pro and iPhone 15 Pro Max share a charging score of 116, the Galaxy S23 outperforms them significantly with a score of 133.

Lastly, in terms of efficiency, the Pixel 8 Pro lags far behind both the Galaxy S23 and iPhone 15 Pro Max. Consequently, the battery performance of the Pixel 8 Pro does not meet expectations when evaluated against the flagship phones of Samsung and Apple.
