Intel’s new chip and LG screen: Remarkable result in battery performance

The new XPS 16 model, introduced by Dell within the scope of CES 2026, stood out among laptops that attracted attention especially with its screen technology and energy efficiency. The screen used in the device, which has a variable refresh rate between 1 Hz and 120 Hz, aims to increase battery performance by minimizing energy consumption when not needed. This approach aims to offer longer usage time, especially in mobile usage scenarios. In addition, this display technology, combined with the Intel Panther Lake processor, which has not yet become widespread, supports its theoretical efficiency claim with practical test results.

According to tests conducted by Notebookcheck, this hardware combination is one of the most efficient laptops ever measured in a Wi-Fi web browsing scenario. In the tests, it is stated that the model with the Core Ultra 325 processor consumes only 1.5 watts of power at idle, and it is stated that approximately 27 hours of usage time is achieved despite the 70 Wh capacity battery. Although these values ​​are based on laboratory conditions, a striking picture emerges when compared with the results obtained in similar tests.

Intel outperforms devices with rival processors

These results show that Apple is ahead of many competing devices, including MacBook and MacBook Pro models. Despite this, it is stated that only two models were able to reach similar levels in past tests. It is stated that one of these devices has a Qualcomm Snapdragon X Plus processor and a larger battery, while the other uses a double battery with a total capacity of 149 Wh. The choice of a 60 Hz fixed screen in both models reveals the importance of the variable refresh rate used in Dell’s solution.

In addition, it seems that LG Display does not limit the technology in question to just one manufacturer. The company announced that it has started mass production of the LCD panel operating in the range of 1-120 Hz, which it calls “Oxide 1Hz”. On the other hand, the OLED version is planned to enter production by 2027. In addition, Intel’s announcement that it is working on similar display technologies with China-based BOE indicates that this approach may become widespread throughout the industry.

It is known that similar screen technologies have been used on mobile devices for a long time. The introduction of a variable refresh rate between 1-60 Hz in the Apple Watch Series 5 model stood out as an important example of energy saving. In addition, variable refresh rates were used at different intervals on smartphones such as Samsung Galaxy S21 Ultra and OnePlus 9 Pro. Apple’s transition to 1-120 Hz screens on Pro iPhone models in 2022 has accelerated the maturation process of this technology.

Although laboratory tests do not exactly reflect real usage scenarios, the data obtained shows that a new level has been reached in terms of energy efficiency in laptops. In addition, it is stated that higher resolution OLED options may have negative effects on battery life. Therefore, users need to balance some hardware preferences for maximum battery performance. In addition to all these, these developments in display technologies are expected to directly affect laptop designs in the coming period.
