Galaxy S21 Ultra is Samsung’s most advanced phone to date. Unlike the S21 and S21 +, the South Korean firm has exclusively maintained its best technologies and advances for the most expensive model, and one of the most important is related to the screen.
It was Samsung that confirmed that the S21 Ultra screen has the new low-power OLED panel developed by Samsung Display. The screen of this phone uses the latest generation LTPO technology that according to Samsung figures is capable of generating more brightness than other OLED screens and still consuming 16% less power.
LTPO technology is not common in the smartphone market, because although we have already seen this type of screens in wearables such as the Apple Watch and the Galaxy Watch, only Samsung has opted for this technology in phones.
The first time a smartphone was launched with an OLED LTPO screen was last year with the Note 20 Ultra, however, the S21 Ultra carries the most efficient generation of these screens, so its energy consumption is better compared to the Note 20 Ultra.
The screen is one of the components that consume the most battery in the phone, and that is one of the reasons why the S20 does not allow the use of the refresh rate at 120 Hz with QHD + resolution since energy consumption shoots up significantly. . The S21 Ultra allows to use the highest refresh rate at the highest resolution as long as the content we are playing supports both specifications, hence we speak of an adaptive refresh rate.
Apple would follow in Samsung’s footsteps
Some rumors that have emerged since last year suggest that two of the four iPhones that would apparently be presented this year would carry LTPO technology, so the energy consumption of the screen would be the most efficient compared to any other iPhone on the market.
The above would allow Apple to bring the 120 Hz refresh rate to an iPhone for the first time without causing energy consumption to skyrocket since many of the criticisms of the iPhone 11 are about the step back in autonomy due to the new 5G connectivity.
The LTPO displays that Apple mounted on the Apple Watch were not supplied by Samsung, but by LG, however, Samsung has provided OLED displays for iPhones, so there is a chance that Apple will bring Samsung’s best LTPO display to your most advanced iPhones.
