| S23 Ultra | ~86 |
The increase in charging power led to slightly higher temperatures for all devices. However, the differences remained minimal, with none of them exceeding 95°F.
Introducing Stress: 4K 60fps Video Recording
To further stress the devices and simulate a demanding usage scenario, we started recording 4K video at 60 frames per second on all phones while they continued to charge. After an additional 5 minutes, here were the results:
| Device | Temperature (°F) |
|---|---|
| iPhone 15 | ~106 |
| iPhone 15 Plus | ~104 |
| iPhone 15 Pro Max | ~107 |
| iPhone 14 Pro Max | ~106 |
| S23 Ultra | ~100 |
The temperatures climbed above 100°F for all iPhones, with the iPhone 15 Pro Max recording the highest temperature at 107°F. The S23 Ultra also showed an increase but remained the coolest.
What Do the Results Tell Us?
From our controlled experiments, a few conclusions can be drawn:
- Charging Speed: The use of a higher wattage charger (65W) resulted in slightly higher temperatures during charging. However, the differences between the iPhone models were not significant.
- Stressful Scenario: Recording 4K video at 60fps while charging led to higher temperatures, surpassing 100°F for all iPhones. This scenario represents an extreme use case, and it’s not a common occurrence during regular smartphone usage.
- Samsung Comparison: The Samsung Galaxy S23 Ultra, while still warming up, maintained lower temperatures compared to the iPhones in all test phases. However, even the S23 Ultra’s temperatures exceeded 100°F under the most stressful conditions.
- Similar Behavior: All tested iPhone models exhibited similar behavior, with the iPhone 15 Pro Max recording the highest temperature but not by a significant margin.
What Does This Mean for iPhone Users?
