Since its launch on Friday, we have all been paying attention to the initial battery life tests of the new iPhone 15. With the new efficient A17 Pro chip manufactured on a 3nm process, it was expected that the iPhone 15 Pro and Pro Max models would lead in battery life. The results, in fact, bring surprises.
More time to enjoy our iPhone
The highly anticipated iPhone 15 Pro Max stands out by far, surpassing all previous iPhones. However, it’s the iPhone 15 Plus that took the crown by accumulating more than 13 hours of screen-on time, becoming the iPhone with the longest-lasting battery recorded to date.
Apple, on its technical specifications page, reveals battery capacity in terms of continuous audio and video playback duration. According to these figures, the iPhone 15 Pro Max leads in video playback with 25 hours, while in audio playback, the Plus surprises with 100 hours, surpassing the Max’s 95 hours. While these numbers are useful, they don’t entirely reflect our daily and real-world phone usage.
This is where Mrwhosetheboss’s tests come in, attempting to simulate a more realistic daily usage pattern by subjecting the device to energy-consuming activities like watching TikTok videos, Zoom calls, video recording, and playing various games. The phone’s screen remains on until the battery is completely depleted.
Comparing to previous generations, all iPhone 15 models outperformed their predecessors. The iPhone 15 Pro was the first to run out of battery after 9 hours and 20 minutes. The base iPhone 15 lasted nearly 10 hours. However, it was the Pro Max and Plus models that took the spotlight. The 15 Pro Max achieved an impressive runtime of 11 hours and 41 minutes. Yet, the 15 Plus surpassed it with 13 hours and 19 minutes.
A figure significantly higher than the previous leader, the iPhone 13 Pro Max, which recorded 11 hours and 19 minutes. This is a clear indication of the excellent work Apple does behind the scenes to ensure that we can enjoy our iPhones for the maximum amount of time possible.
