iPhone 15 Plus delivers the best battery life, not iPhone 15 Pro Max

Apple has introduced several meaningful changes in this year’s iPhone 15 and iPhone 15 Plus models like the A16 Bionic chip, Dynamic Island, 48MP Main camera with up to 2x Telephoto, and USB-C port.

In addition, the new 6.1-inch base models also feature slightly larger batteries than their predecessor iPhone 14 and iPhone 14 Plus models to deliver longer battery life.

However, it appears that the new iPhone 15 Plus delivers longer battery life not only than the iPhone 14 Plus but also than the iPhone 15 Pro Max.

The highest-end iPhone 15 Pro features the largest battery in the new iPhone 15 series, and surprisingly, the iPhone 15 Plus features the second largest battery in the series, not the iPhone 15 Pro. Differences in battery sizes impact the battery life performance of each model.

iPhone 15 Plus gives the longest battery life while the iPhone 15 Pro gives the lowest

Tom’s Guide and YouTuber @Mrwhosetheboss tested the battery life of each iPhone 15 model to see which one delivers the longest battery life.

@Mrwhosetheboss battery test involved social media, audio and video streaming, camera usage, ChatGPT, and other workflows, and Tom’s Guide‘s test involved continuous web surfing.

Interestingly, the results of two different types of testing drew the same conclusion; The iPhone 15 Plus took the crown with the longest battery life while the iPhone 15 Pro Max came second. The iPhone 15 Pro delivered the lowest battery life in the series.

iPhone 15 Plus - battery life

Without a doubt, all of the iPhone 15 models deliver better battery life than their predecessors and even a few older Pro models because of advanced processors and larger batteries.

Within the latest series, users should opt for the iPhone 15 Plus or 15 Pro Max if they prioritize battery life. iPhone 15 Plus costs $100 more than iPhone 15, maybe Apple is incentivizing consumers to opt for the 6.7-inch base model with a larger display and best battery life.

When we did a reviews roundup of the iPhone 15 and iPhone 15 Plus, we predicted that the 15 Plus would be the base model this year for the reasons mentioned above.
