![]() ![]() Refresh rates also depend on the CPU used, because of something called frame rates. Again, theoretically, this means it isn’t as efficient as Apple’s technology. Which means that a display using this technology will run at 30Hz at its lowest and 144Hz at its highest, moving to the closest frequency that an app requires. In this, the refresh rate moves between 30, 48, 50, 60, 90, 120 and 144Hz. For instance, here’s a Xiaomi blog that explains a 7-stage AdaptiveSync technology. This isn’t what Android smartphones offer. These displays have higher adaptability when it comes refreshing, which is why Apple’s displays can shift between 10 to 120Hz, which theoretically makes them more battery efficient. Now, Apple’s displays also benefit from the fact that they use low-temperature polycrystalline oxide (LTPO) displays. Presumably, the refresh rate will drop to its lowest when you’re looking at one page for a long time, while it will push to its highest when you’re in the middle of a heated session of Battlegrounds Mobile India (BGMI). Hence, Apple is essentially putting its own proprietary tools that recognise what’s happening on your iPhone 13 Pro and Pro Max, and tweaking the refresh rate appropriately. ![]() If your phone is constantly refreshing at 120Hz, chances are that it will run out of battery faster. The feature is also important because higher refresh rates consume more battery. ![]() However, that doesn’t mean that the display needs to refresh as fast for both these use cases. For instance, fast paced first person shooter (FPS) games are better when refresh rates are higher, while navigating the user interface (UI) also feels smoother with such features. Higher refresh rates can help in a lot of ways. It means that instead of always refreshing at 120Hz, the displays on the iPhone 13 Pro and the Pro max will switch between 10Hz and 120Hz as and when required. In essence, ProMotion isn’t any different from what Android smartphone makers have called “variable refresh rate”. ProMotion also improves display quality and reduces power consumption by automatically adjusting the display refresh rate to match the movement of the content”. With ProMotion, Apple Pencil is even more responsive with an industry-best, 20-millisecond latency for even more fluid and natural drawing. ![]()
