iPhone surpasses 35 smartphone models in battery life.

Large-scale testing has shown that iPhones achieve high real-world battery life despite having smaller battery capacities than many other smartphones currently on the market.

In a recent large-scale test, CNET subjected 35 popular smartphone models in the US market to two rigorous tests to assess real-world battery life.

The first test involved three hours of continuous video playback over Wi-Fi at maximum screen brightness, while the second was a 45-minute high-intensity activity sequence including gaming, watching videos, video calls, and browsing social media. The final result was the average of the two tests.

Convincingly topping the rankings is the iPhone 17 Pro Max with a 5,088 mAh battery capacity, not the most impressive number in terms of specifications. However, Apple 's flagship model has proven its superior efficiency thanks to the perfect combination of the power-efficient A19 Pro chip and deep optimization between the hardware and the iOS 26 operating system.

More notably, the basic iPhone 17 model with a battery of only 3,692 mAh tied for second place with the OnePlus 15, which boasts a massive 7,300 mAh battery.

This difference shows that larger battery capacity doesn't necessarily mean better actual usage time, especially as many manufacturers are switching to silicon-carbon battery technology to increase capacity without making the device thicker.

While some phones using silicon-carbon batteries, such as the OnePlus 15 or Poco F7 Ultra, perform well, Apple's products still stand out due to their more efficient power management.

When calculating average brand scores, Apple continues to lead with 91.7%, significantly ahead of OnePlus in second place. Other major brands such as Motorola, Samsung, and Google follow behind. This further confirms Apple's position in providing users with a stable and long-lasting battery experience.

In another survey conducted by CNET in collaboration with YouGov in September 2025, battery life was the most important factor when consumers decided to buy a new smartphone, second only to price. Therefore, this test result has significant practical implications, especially for those who frequently use their phones intensively.

Despite the push towards silicon-carbon battery technology by many manufacturers, Apple remains committed to traditional solutions and continues to demonstrate that software optimization and processor chip integration are key to achieving the best battery performance. This result once again confirms the strength of the Apple ecosystem in the increasingly fierce smartphone race.
