iPhone 17 Pro Max Battery Test Outlasts Galaxy S25 Ultra

iPhone 17 Pro Max Shatters Records with 13-Hour Real-World Battery Life.Apple’s new iPhone 17 Pro Max has set a new benchmark for smartphone endurance. Independent testing reveals it delivers over 13 hours of continuous real-world use. This performance solidifies its position as the current battery life champion.The result comes from a rigorous mixed-usage test designed to mimic actual daily activity. It significantly outperforms its predecessor and key Android rivals in this critical metric.

Bigger Hardware and Smarter Software Drive Unprecedented Efficiency

The iPhone 17 Pro Max’s stamina is no accident. Apple engineers equipped it with a physically larger battery cell. This provides a fundamental increase in available power.The new A19 Pro chip is built on an advanced 2-nanometer process. This allows for dramatically improved power efficiency. According to Reuters, this node shrink is a key industry milestone.Improved thermal management also plays a crucial role. A new graphite cooling system prevents performance throttling. This keeps the phone running efficiently even during intensive tasks.

Comparative Testing Reveals a Clear Winner

A recent video test by popular tech reviewer MrWhoseThe Boss put the phones through their paces. The test involved social media scrolling, video recording, and app switching.The iPhone 17 Pro Max lasted a full 13 hours before shutting down. The previous model, the iPhone 16 Pro Max, managed 12 hours and 15 minutes. Samsung’s flagship Galaxy S25 Ultra completed the test in 11 hours and 50 minutes.The smaller iPhone 17 models showed more modest gains. The standard model lasted approximately 10.5 hours. The ultra-thin iPhone Air, however, struggled significantly due to its compact design.

How does the iPhone 17 Pro Max battery compare to last year’s model?

The new model offers a noticeable improvement. It lasts approximately 45 minutes longer in demanding mixed-usage tests. This is due to its larger battery and more efficient A19 Pro chip.

Did the iPhone 17 Pro Max beat the Samsung Galaxy S25 Ultra?

Yes, it achieved a clear victory. The iPhone 17 Pro Max lasted over an hour longer in the same real-world battery test. This gap highlights Apple’s recent focus on battery optimization.

Why is the iPhone Air’s battery life so much shorter?

Its ultra-thin design severely limits space for a battery. Apple prioritized form factor over battery capacity for that specific model. This results in a compromise on endurance.

What activities were included in the battery test?

The test simulated common daily phone use. It included scrolling through social media, recording video, and using messaging apps. This provides a more realistic result than simple video playback tests.
