Test results for the battery life of the iPhone 17 Pro Max have been unveiled - and they left us astonished
The much-anticipated iphone 17 pro max has made an impressive debut, securing a spot at number 7 in the best phone battery life rankings.
In an in-house TG battery test, the iphone 17 pro max showcased its endurance, lasting an impressive 17 hours and 54 minutes. However, it's worth noting that its predecessor, the iphone 16 pro max (Sept 2024), managed a similar runtime of 17 hours and 35 minutes in the same test.
In a YouTube test, the iphone 17 pro max lost just 12% of its battery after 5 hours of playback at 50% brightness, outperforming the iphone 16 pro max, which lost 25%. The Samsung Galaxy S25 Ultra, on the other hand, lost 20% of its battery during the same test.
While the iphone 17 pro max's battery life is commendable, its charging speed is still a point of contention. Apple's new 40W charger manages to charge the iphone 17 pro max 35% from 0% after 15 minutes, but it's still slower than the Galaxy S25 Ultra at the 15-minute mark, which charges 37% using a 45W Samsung charger.
Interestingly, Xiaomi's Xiaomi 15 Ultra, with a larger 5,410 mAh battery, offers a runtime close to 18 hours in standard tests. Despite the iphone 17 pro max's around 5,088 mAh capacity, it achieves longer battery life, but falls short in comparative charging speed and endurance tests.
It's important to note that all phones tested, including the iphone 17 pro max, should easily last a full day without any trouble. Other notable performers include the Asus ROG Phone 9 Pro, which lasts over 20 hours on the battery life test.
For a comprehensive review of the new iphones' performance, check out the iphone 17 review, iphone 17 pro review, and iphone air review. Apple's new charging tech has only somewhat overcome its historic charging speed weakness, leaving room for improvement in future models.
The iphone 16 pro max (Sept 2025 retest) showed a slight reduction in battery life compared to its initial test results, highlighting the importance of regular battery maintenance and upgrades in future models. The Samsung Galaxy S25 Ultra, despite its strong charging speed, also faced a slight drop in battery life after a year of use.
In conclusion, the iphone 17 pro max offers impressive battery life, but its charging speed remains a point of contention compared to some of its competitors. For those prioritizing battery life, the Xiaomi 15 Ultra and Asus ROG Phone 9 Pro are also worth considering.
