OnePlus 9 Pro, analysis: approaching perfection

We thoroughly analyze the new OnePlus 9 Pro, a mobile that boasts design, power and, above all, a new camera system co-designed with Hasselblad.

What is LTPO technology

LTPO stands for Low temperature polycrystalline oxide, in Spanish Low temperature polycrystalline oxide

. It is a technology that is used in OLED panels, not only in smartphones, because Apple also used it in its latest generation of Apple Watch. This technology has a key feature and that is that it reduces its update frequency automatically, in order to save battery on the device.

It is an OLED panel that uses a special driver and an improved ambient brightness sensor. Thanks to these two elements, this panel will be able to reduce its update frequency when it is inactive, which helps to reduce energy consumption. This will help increase battery life. In the case of the OnePlus 9 Pro, such screen power consumption is reduced by 50% as a result of LTPO technology.

Variable refresh rate

The key feature in an OLED panel with LTPO technology is the automatic variable refresh rate. That is, if you are gaming, the phone will use the maximum refresh rate it has (either 120 Hz or 60 Hz, for example), but when the device is idle or you are simply reading or viewing photos, the refresh rate will go from automatically to be 1 Hz. You will not have to do anything to change that rate.

This change means that the screen goes from refreshing 60, 90 or 120 times per second to doing it 60 times per minute (1 Hz). Energy consumption is significantly reduced, because the maximum refresh rate is used only when it is really necessary. In addition to preventing the user from having to configure this manually at all times. Comfort is gained and the battery life of the phone is extended in this way. In addition, the user experience is optimal, because the screen adapts to what you are doing.

It is well known that the screen is the component that consumes the most battery in a phone. An OLED panel consumes less than an LCD panel, because each pixel is independent, so when there is black on the screen, less is consumed because that pixel is turned off. LTPO technology contributes to lower consumption by adjusting the refresh rate automatically, adapting to the use made of it. Together they help put a lot more strain on your phone’s battery.
