Apple’s iPhone 17 Pro Max Dominates Battery Life Rankings, Leaving Samsung in the Dust

In a comprehensive battery life showdown featuring 35 of the most popular smartphones on the market, Apple’s iPhone 17 Pro Max has emerged as the undisputed champion, delivering the longest-lasting performance among all competitors tested. The Cupertino tech giant didn’t just win—it dominated, with another Apple device securing the runner-up position in a surprising twist that has industry analysts buzzing.

The Battery Life Battle: iPhone 17 Pro Max Takes the Crown

When it comes to smartphone endurance, the iPhone 17 Pro Max has set a new benchmark that competitors are struggling to match. In rigorous testing conducted by CNET, Apple’s flagship device outperformed 34 other smartphones across various brands, cementing its position as the go-to choice for users who demand all-day power without the anxiety of searching for an outlet.

What makes this victory particularly impressive is that the iPhone 17 Pro Max didn’t rely on having the largest battery capacity in the competition. With a 5,088 mAh battery, it actually fell short of some competitors that boasted significantly larger power cells. Instead, Apple’s triumph demonstrates the remarkable efficiency of its A19 Pro chip combined with the optimization capabilities of iOS 26.

“Its 5,088-mAh battery capacity wasn’t the largest, but it shows just how efficient Apple’s A19 Pro chip and iOS 26 are,” noted CNET in their comprehensive analysis. This efficiency-first approach has become Apple’s signature strategy, proving that raw battery size isn’t everything when intelligent power management is implemented at the hardware and software level.

The Unexpected Runner-Up: iPhone 17 Surprises Everyone

Perhaps the most shocking revelation from CNET’s testing wasn’t just Apple’s victory, but which specific model claimed second place. The iPhone 17, Apple’s base model, secured the silver medal position, outperforming more expensive Pro variants and leaving industry experts questioning their assumptions about premium features and battery performance.

“The iPhone 17 has the smallest-capacity battery of any of the top phones, proving that battery size doesn’t matter,” CNET emphasized. This unexpected result serves as another testament to Apple’s engineering prowess, where the company’s custom silicon and meticulously optimized operating system work in perfect harmony to deliver exceptional battery life regardless of the specific model.

This achievement is particularly noteworthy because it means that even budget-conscious consumers who opt for Apple’s standard iPhone 17 can enjoy class-leading battery performance without paying the premium price tag associated with Pro models. It’s a win-win scenario that strengthens Apple’s position across its entire product lineup.

Samsung’s Absence from the Podium Raises Questions

One of the most surprising aspects of the battery life comparison was the complete absence of Samsung devices from the top ten rankings. Despite Samsung being Apple’s closest competitor in the premium smartphone market, not a single Galaxy model managed to crack the list of longest-lasting phones.

This absence is particularly striking given that Samsung offers a diverse range of devices across multiple price points and typically emphasizes battery life as a key selling feature. The fact that nine different Samsung handsets were tested without any achieving top-tier battery performance suggests potential areas for improvement in Samsung’s power management strategy.

Industry analysts are already speculating about what this means for Samsung’s competitive position. Battery life is consistently ranked as one of the most important features for smartphone buyers, often taking precedence over camera quality, display resolution, or even processing speed. Samsung’s inability to compete in this crucial category could have significant implications for its market share, especially as consumers become increasingly aware of these performance differences.

OnePlus and Motorola: The Dark Horse Contenders

While Apple dominated the top positions, the testing revealed some interesting performances from other manufacturers. OnePlus, in particular, demonstrated strong battery life capabilities, with the OnePlus 15 securing the third position overall. This performance helped OnePlus claim the second spot in the aggregate battery life rankings across all tested devices.

Motorola also proved to be a solid performer, with its Edge model finishing fifth in the individual competition. The company’s overall battery life performance was good enough to earn it the third position in the manufacturer-wide comparison, suggesting that Motorola has found an effective formula for balancing performance and power efficiency.

These results indicate that while Apple may be leading the pack, there’s healthy competition emerging from manufacturers that aren’t typically associated with premium battery life. This could signal a shift in the smartphone market, where battery endurance becomes an increasingly important differentiator as hardware specifications across brands become more similar.

The Testing Methodology: How Battery Life Was Measured

Understanding how these results were obtained is crucial for interpreting their significance. CNET employed a comprehensive testing methodology designed to simulate real-world usage patterns while maintaining consistency across all devices tested.

The testing process involved two primary components: an anecdotal stress test and a video streaming test. Each phone began with a fully charged battery at 100%, and the tests were conducted under controlled conditions to minimize variables that could affect the results.

“To standardize our testing and minimize variables as much as possible, we run each phone through an anecdotal stress test and a video streaming test, starting with the battery at 100%. The results from each test show the remaining battery percentage,” explained CNET. “We averaged the two results to determine an overall score.”

This dual-testing approach is particularly valuable because it captures different usage scenarios. The anecdotal stress test likely involved a mix of activities including web browsing, social media usage, messaging, and other common smartphone tasks. The video streaming test specifically challenges the device’s power management capabilities under sustained high-demand conditions, as video playback is one of the most battery-intensive activities smartphone users engage in regularly.

Why Battery Life Matters More Than Ever

The significance of these battery life findings extends beyond mere technical specifications. In today’s smartphone-dependent world, battery performance has become a critical factor that influences purchasing decisions, user satisfaction, and even safety considerations.

Modern smartphones have evolved far beyond their original purpose as communication devices. Today’s handsets function as cameras, digital wallets, navigation systems, entertainment centers, and productivity tools all rolled into one portable package. This multifunctionality means that users rely on their phones throughout the entire day, often for critical tasks like navigation while driving, accessing emergency services, or maintaining communication during natural disasters or power outages.

A phone that runs out of power halfway through the day isn’t just inconvenient—it can be disruptive to travel plans, cut off communication with family and colleagues, and in some situations, create genuine safety concerns. Strong battery performance enables users to confidently utilize power-hungry features like 5G connectivity, GPS navigation, and video streaming without constantly monitoring their battery percentage or carrying portable chargers.

As smartphones continue to grow more capable, with artificial intelligence features, advanced camera systems, and always-on displays becoming standard, long battery life has evolved from a convenient feature to an essential requirement. It’s no longer just about convenience—it’s about reliability, productivity, and peace of mind.
