What's the story

Dell's latest laptop, the XPS 16, is making waves with its groundbreaking battery life. The device features a unique display that can adjust its refresh rate from 1Hz to as high as 120Hz. This feature helps save power when high-speed visuals aren't needed. A version of the laptop with this innovative screen and an Intel Panther Lake chip has broken records in Notebookcheck's Wi-Fi web browsing test.

Efficiency record

The laptop drew as little as 1.5W at idle

The Dell XPS 16, powered by the Core Ultra 325 chip, drew as little as 1.5W at idle. The laptop lasted nearly an incredible 27 hours of web browsing on a relatively small 70W-hour battery pack. This is more than any MacBook or MacBook Pro has managed in Notebookcheck's tests since they began in 2014.

Battery comparison

The laptop beats nearly all machines tested since 2014

The battery life of the Dell XPS 16 beats all but two other laptops tested by Notebookcheck. One of those was a Qualcomm Snapdragon X Plus-powered machine with an 84Wh pack and a basic 60Hz display. The other had two batteries totaling up to an impressive 149Wh but also sported a standard 60Hz screen.

Real-world usage

Real-world battery life can be significantly lower than fixed tests

It's worth noting that real-world battery life can be significantly lower than what fixed tests show. However, the combination of Dell, Intel, and LG Display tech in the XPS 16 makes it look like a new champion in the battery life department. For those looking for maximum battery efficiency, opting for a non-OLED and non-touchscreen display with a resolution of 1920 x 1200 pixels is recommended.
