Apple’s iPhone 18 Pro Max Tops Smartphone Battery Comparison
In a recent assessment of battery performance across 32 smartphones, Apple’s iPhone 18 Pro Max has emerged victorious, securing the prestigious top position.
Notably, several other iPhone variants also ranked among the most robust performers. As reported by CNET, the evaluation involved two rigorous tests, accumulating to a total duration of three hours and 45 minutes.
The initial segment focused on battery depletion while streaming video over Wi-Fi at maximum brightness for three hours, while the second segment simulated typical daily activities, including video playback, video calls, gaming, and social media usage for an additional 45 minutes.
Both tests commenced with a full battery charge of 100%. CNET averaged the remaining battery percentages post-testing to establish a hierarchy among the smartphones.
Remarkably, the iPhone 18 Pro Max and Apple’s inaugural foldable, the iPhone Duo, delivered exceptional performance in mixed-use scenarios, concluding with 99% battery remaining.
Following closely was Google’s Pixel 11 Pro XL, exhibiting a commendable 97% battery life, a notable improvement from the Pixel 10 Pro XL’s 93% outcome.
In terms of video streaming prowess, the smaller iPhone 18 Pro excelled, retaining an impressive 94% battery after three continuous hours of playback.
The iPhone 17 also showcased formidable results across both assessments, sharing the limelight with Motorola’s Razr and Razr Ultra.
CNET attributes the exemplary performance of the iPhone 18 Pro Max to its larger battery capacity in comparison to the iPhone 17 Pro Max, alongside the enhanced efficiency of the A20 Pro chip and optimizations brought forth by iOS 27.
Despite achieving results on par with the iPhone 18 Pro Max during the mixed-use test, the $1,999 iPhone Duo only managed to secure the fourth position overall.
Its aggregated performance matched that of the $699 iPhone 17e and the $1,400 Motorola Razr Ultra, consequently placing Apple’s foldable device alongside two considerably more budget-friendly options.
For the second consecutive year, Apple has reclaimed the title in CNET’s manufacturer rankings for average battery performance, evaluated among brands with multiple models tested. Second place was claimed by OnePlus.
Nevertheless, the overarching findings suggest a stagnation in smartphone battery life enhancements over recent years. CNET noted that phones assessed in 2026 exhibited nearly identical average performances as those tested in 2025 and 2024.
It is imperative to recognize that larger batteries do not invariably equate to prolonged battery life. Factors such as display technology, processor efficiency, and other hardware components substantially influence power consumption. Consequently, battery capacity alone fails to dictate the longevity of a phone between charges.
CNET additionally underscored the iPhone 17 and iPhone 17e as commendable alternatives for consumers seeking enhanced battery life without breaking the bank.
Beyond Apple’s offerings, the $500 Motorola Moto G Stylus and the $600 Motorola Edge also distinguished themselves, earning spots in the overall top ten rankings.
