Apple’s iPhone 18 Pro Max has reportedly secured the top position in a battery endurance test involving 32 popular smartphones, outperforming competitors in an assessment covering video streaming, gaming, social media browsing and calls.
According to the reported results, the iPhone 18 Pro Max retained 99% battery life in the mixed-use assessment, sharing the top position with Apple’s latest foldable device, the iPhone Duo.
Google’s Pixel 11 Pro XL followed with 97%, while the standard iPhone 18 Pro delivered the strongest performance in the continuous video-streaming category, retaining 94% battery after three hours.
How the Battery Test Was Conducted
The assessment involved two testing stages lasting nearly four hours in total.
During the first stage, researchers measured battery consumption over three hours of Wi-Fi video streaming with screen brightness set to maximum.

The second stage involved 45 minutes of mixed activities, including social media browsing, gaming, video playback and phone calls. The remaining battery percentages were used to calculate the devices’ comparative rankings.
What Gives the iPhone 18 Pro Max Its Battery Advantage?
The reported results have been attributed to a combination of hardware and software improvements.
The iPhone 18 Pro Max is described as featuring a higher-capacity battery, alongside power-efficiency improvements from Apple’s A20 Pro chip and battery optimisation features in iOS.
The iPhone Duo also performed strongly in mixed-use testing, although its results reportedly placed it only slightly ahead of more affordable models such as the iPhone 17e and Motorola Razr Ultra.
Alternatives for Battery-Conscious Buyers
The assessment also identified the standard iPhone 17 and Motorola’s mid-range Edge series as potential alternatives for consumers seeking dependable battery performance without paying flagship prices.
The findings highlight the importance of combining battery capacity, processor efficiency and software optimisation to deliver longer battery life as smartphone manufacturers introduce increasingly demanding displays and features.
