Rumors that the iPhone 13 Pro will feature an adaptive refresh rate display have resurfaced again, with the latest rumors revealing that the LTPO panel planned for the PRo device will significantly reduce the screen's power consumption.

According to industry sources, DigiTimes reports that the low-temperature polycrystalline oxide (LTPO) display that Samsung and LG will produce for the iPhone 13 Pro will not only provide a 120Hz refresh rate display for Apple's next flagship smartphone, but will also reduce the phone's reportedly reduce the phone's power consumption by 15% to 20%.

Given that the iPhone 13 Pro is expected to feature a powerful new chip, likely A15, with a high refresh rate display and 5G connectivity, reducing power consumption will be critical to ensure that the next generation iPhone does not run out of charge before the day is over The next generation of iPhones will not run out of charge before the day is over.

Currently, the iPhone 12 Pro Max is the Apple phone with the longest battery life, lasting 11 hours and 54 minutes in a battery test in which users continued surfing the web until the phone's battery ran out via LTE or 5G. In this test, the user uses an LTE or 5G line and continues surfing the web until the battery runs out. Unfortunately, neither the iPhone 12 nor the iPhone 12 Pro could accomplish that.

These models have 5G connections and 60Hz OLED displays. Therefore, the higher refresh rate will consume more battery power.

However, with TPO panels, a high refresh rate panel can be slowed down to a single digit when a fast refresh rate is not needed, such as when simply viewing photos rather than playing a fast-paced game. We have seen LTPO panels suppress battery life in the Samsung Galaxy S21 and other devices, but they have not surprised us with their battery durability.

However, Apple has worked on optimization in the past and produced phones with strong battery performance. So combining this with LTPO panels and reducing power consumption by up to 20% could lead to a future iPhone Pro that delivers flagship screen and connectivity without compromising durability.

With an LPTO display, the iPhone 12 Pro would at least be on par with the top Android flagship phones of 2021 so far. However, it is a bit disappointing that not all iPhone 13 models are expected to feature LTPO technology.

As for other iPhone 13 upgrades, the display notch is expected to be smaller, the entire lineup will have a sensor-shifted camera with image stabilization, and the iPhone 13 Pro will have an improved ultra-wide camera.

We expect software improvements for a smarter iOS experience and additional camera features such as astrophotography and portrait mode video Touch ID is also said to come in the form of a fingerprint sensor under the display.

Expect rumors and leaks to accumulate as the year progresses, as the iPhone 13 series is promising to return in the September reveal window. We are quietly optimistic that the upgrades brought by the iPhone 13 should give it a good chance at making it to our best phones list.
