Despite the outstanding photo quality of the Google Pixel 7 series of smartphones, Google’s flagships have long suffered from complaints of poorer battery life and cellular stability than their competitors like Apple, Xiaomi and OnePlus. And the main culprit has always been assumed to be Google’s power-intensive Tensor chipsets manufactured on Samsung’s foundry.
With the recent release of the Google Pixel 8 series this week, Google fans were curious by whether the new Tensor G3 chipset would bring better battery life to the Pixel lineup. However, based on the small fine print on Google’s “Compare Phones” section on its website, it is revealed that the Google Pixel 8 series not only has the same bad battery life as the Pixel 7 series but is also worse than the Pixel 6 and 6 Pro that were released 2 years ago.
As shown in the official fine print above, the latest Google Pixel 8 and 8 Pro’s battery lasted an average of 31 hours from Google’s own internal testing, which makes both devices on par with the Pixel 7a, Pixel 7, and Pixel 7 Pro from last year. In addition, when compared to the Pixel 6 and 6 Pro launched 2 years back, the Pixel 8 and 8 Pro’s battery life is worse because they only last 3 hours shorter than Google’s own Pixel 6 at 34 hours. We compiled a table below to view Google’s claims of average battery life in its Pixel lineup in descending order, alongside the battery capacity of each Pixel smartphone.
| Rated Average Battery Life (based on Google’s tests) | Battery Capacity | |
| Pixel 6 Pro | 34 hours | 5003 mAh |
| Pixel 6 | 34 hours | 4614 mAh |
| Pixel 8 Pro | 31 hours | 5050 mAh |
| Pixel 8 | 31 hours | 4575 mAh |
| Pixel 7a | 31 hours | 4385 mAh |
| Pixel 7 Pro | 31 hours | 5000 mAh |
| Pixel 7 | 31 hours | 4355 mAh |
| Pixel 6a | 29 hours | 4410 mAh |
For context, external testers like TechDroider on YouTube, have tested the battery life of last year’s Google Pixel 7 Pro against the Samsung Galaxy S23 Ultra, OnePlus 11, Xiaomi 13 Ultra, and Apple’s iPhone 15 Pro Max. Their results on battery life are as shown in Table 2.
| Tested Battery Life | Battery Life Increase (Compared to Pixel 7 Pro) | |
| iPhone 15 Pro Max | 10 hr 31 mins | 128% longer |
| Samsung Galaxy S23 Ultra | 10 hr 27 mins | 127% longer |
| Xiaomi 13 Ultra | 10 hr | 122% longer |
| iPhone 14 Pro Max | 9 hr 59 mins | 122% longer |
| OnePlus 11 | 9 hr 48 mins | 119% longer |
| Google Pixel 7 Pro | 8 hr 13 mins | – |
As shown, the Pixel 7 Pro is significantly lagging behind its competitors in the battery life department of the premium smartphone market by around 2 hours in battery life. And the battery life result of 8 hours and 13 mins is much shorter than Google’s official claim of 31 hours on the Pixel 7 and 7 Pro.
If Google’s claims of the Pixel 8 and 8 Pro’s battery are true, then the Pixel 8 series has the same bad battery life of “31 hours” as the Pixel 7 and possibly worse battery life than the Pixel 6 series as well.
