A popular tech reviewer known for in-depth hardware testing released a video that pits the latest iPhone 15 against a range of Apple smartphones to explore which model truly lasts longer in everyday life. The test scenario mirrors typical daily usage patterns: streaming short videos, participating in video meetings, capturing high-quality video, and playing graphics-intensive games. Across all devices, the battery endured through these activities until each one finally exhausted its charge. The results offered surprising insights about how different generations of iPhones perform under real-world conditions and how newer hardware translates into endurance on a single charge.
The breakdown of performance revealed clear leaders and some surprises. The iPhone 14 lagged behind the rest, showing the shortest runtime in the group at a little over nine hours. The newly released iPhone 15 Pro followed closely, surviving just over nine hours and a quarter. The standard iPhone 15 managed a longer run, approaching ten hours of continuous use. These numbers illustrate a meaningful shift in how Apple’s newer devices handle sustained workloads compared with their predecessors, suggesting incremental gains in efficiency across the lineup.
When examining the higher-end models, the iPhone 13 Pro Max delivered robust stamina, crossing the eleven-hour mark with ease. The improved iPhone 15 Pro Max edged past it, reaching about eleven and a half hours before powering down. Yet the standout performer in this comparison was the iPhone 15 Plus, which exceeded thirteen hours of continuous operation without a refill. This model demonstrated that larger battery capacity combined with optimized software can translate into noticeably longer screen-on time, even in the face of demanding tasks like gaming and video capture.
Across the broader landscape of flagship phones, the iPhone 15 Pro’s battery life falls somewhere near the lower end of the spectrum. Still, the measured duration of roughly nine hours holds up reasonably well when seen alongside Android flagships tested in similar conditions in prior years, where devices from competing brands often landed in the six-to-eight hour range. The takeaway is that Apple’s latest generation provides competitive endurance, particularly when you consider the overall balance of performance, display quality, and power efficiency that these devices deliver in day-to-day use.
A common caution that has circulated in Apple retail settings—about using cables from other brands for charging—appears less about performance and more about safety standards. While third-party cables can function, the recommendation emphasizes reliability and compliance with Apple’s safety guidelines to minimize risks during charging sessions. This reminder underscores the broader point that consumers should pair devices with properly rated accessories to maintain battery health and safe operation over the long term.
