The next iPhone release, tipped to be called iPhone 12 when unboxed, is expected to impress even more than the last installment and one feature upgrade that the series will supposedly bring is a 120Hz screen refresh rate. If this is the plan, Apple has inadvertently pointed to its implementation, and big thanks to iOS 14.

The upcoming mobile OS was introduced via the 2020 WWDC keynote on Monday and is now available for beta testing. Those who took iOS 14 for a spin made several discoveries and one of the notables is an option to limit the display frame rate.

The information was shared on social media by tech personality Ben Geskin, and he wondered aloud why the setting is now part of the upcoming operating system when the latest iPhone models have a display with screen refresh rate maxed out at 60Hz. It can only be deduced that the sequel to the iPhone 11 will boast 120Hz frame rate, which by the way has been a feature long enjoyed by Android phone users.

According to WCCFTech, it could be that the iOS 14 setting option is a case of a mix up that likely will be cleaned out in the final cut. That's because 120Hz display is already available in the iPad Pro so it shouldn't come as a surprise that the toggle switch is there.

But then again, Geskin spotted the setting option on an iPhone and it's only safe to assume that already there is a provision on iOS 14 for the arrival of display feature. If Apple will follow through with the hint, it should be noted that the frame rate limit is there for users to conserve battery juice.

Android flagships with 120Hz display are a joy to use indeed, especially in the case of serious mobile gamers. The gaming experience is buttery smooth but the function is proven to be a power hog. While gaming itself will run down the battery rather swiftly, a high display refresh rate will only accelerate the drain.

That is why it's good guesswork that if Apple will deliver 120Hz display with the iPhone 12 rollout, the option to limit the frame rate will be made available. Tom's Guide said the toggle switch will be there so users can decide to choose between stunning display function or longer battery life.

In any case, the next iPhone from Apple is touted to sport OLED display across the board and the expectation is there will be four variants to cherry-pick from. However, Forbes said it's most likely that 120Hz display is exclusive for those who would buy the iPhone 12 Pro edition, and possibly the same is true for the iPhone 12 Pro Max.
