IPhone 13 vs. 13 Pro battery life test, dynamic refresh technology is indeed effective but not so obvious

Looking at the parameters, it seems easy to think that the iPhone 13 with a slightly larger battery capacity (3227mAh) lasts longer than the iPhone 13 Pro (3100mAh) because they all have the same 6.1-inch screen and almost the same processor, but the 13 Pro has 120Hz Swipe the screen high.
But don’t forget that Apple’s ProMotion dynamic refresh technology allows the screen to have a refresh rate as low as 10Hz when needed. This is actually an indirect power-saving function. This is why Apple stated that the battery life (22 hours, video playback time) of the 13 Pro can be longer than that of the iPhone 13 (19 hours).

But no one can watch videos with their mobile phones all the time, so the actual measurement of PhoneBuff is closer to reality: watching videos, flipping through web pages with robotic arms, playing games, swiping social networks, etc.

As a result, the battery life of the iPhone 13 is 9 hours and 42 minutes, while the 13 Pro is 9 hours and 51 minutes.

The iPhone 13 Pro does have a longer battery life than the 13, but the difference is less than 3 hours. In the test, it only increased by 9 minutes. Therefore, ProMotion can help overcome the power saving of the Pro series, but it seems that the gap is not as obvious as the official one said.
