The iPhone 17 Pro Max becomes the 'champion' in battery life.

According to MacRumors , in the world of smartphones , users often mistakenly believe that the higher the mAh rating of a battery, the longer the usage time. However, the results of a large-scale test recently published by the technology website CNET have completely dispelled this notion.

Apple's spectacular dethroning of the 'king of batteries'.

Outperforming 35 other smartphone models released in the US throughout 2025, the iPhone 17 Pro Max has officially become the 'champion' in terms of battery life. Notably, this device only has a 5,088 mAh battery, significantly smaller than many Android flagships which typically feature batteries ranging from 5,500 to 6,000 mAh.

Apple's success can be attributed to two core factors: the extremely high performance of its Apple Silicon chips and the optimization of its iOS software. Instead of cramming in an oversized battery that increases the device's weight, Apple focuses on saving energy on even the smallest tasks.

Not only did the Pro Max line shine, the standard iPhone 17 also surprised everyone by tying for second place with the OnePlus 15. Notably, the iPhone 17 achieved this position despite having the most 'modest' battery capacity among the leading devices. This demonstrates Apple's thorough implementation of energy efficiency optimization across its entire new product line.

Rigorous testing process

To arrive at these results, CNET conducted high-pressure tests to simulate real-world conditions:

Streaming test : Watch video with a Wi-Fi connection at maximum brightness for 3 consecutive hours.
Comprehensive endurance test : 45 minutes of continuous, strenuous tasks including playing games, browsing social media, and making video calls.

The average results show that the iPhone 17 Pro Max is unrivaled in its ability to maintain durability under high intensity use.

Are Samsung and Google running out of steam?

The report also ranked battery performance by brand. Apple and OnePlus shared the top two spots in battery reliability. Meanwhile, other leading brands like Samsung and Motorola ranked third and fourth, respectively. Notably, Google , despite having a rather impressive Pixel 10 series, still had to settle for fifth place overall.

In the modern smartphone race, battery capacity is just the tip of the iceberg; intelligent power management is what truly helps users maintain usage time throughout the day.
