At CES 2025, while many tech innovations dazzled the crowd, nothing set the stage quite like the latest all-day laptops. Forget about the enticing stretchable screens and massive 115-inch televisions – the standout star was the ability to power through demanding days without ever needing to recharge.

During my extensive four-day venture at CES, which involved an exhausting 66,326 steps traversing from press conferences to cocktail receptions, I was equipped with laptops that boasted an amazing battery life. The experience was liberating: engaging in note-taking, photo editing, and social media updates without the nagging worry of running low on battery power.

The Arm and Intel Uprising

These laptops represent the dawn of a new generation of Windows devices crafted for all-day efficiency, shedding the need for a charger. The two models I tested, Lenovo's Yoga Slim 7i and Slim 7x, stood out as contenders that could rival Apple’s MacBook Air, known for its stellar M-series processors that set the benchmark for ultra-portable computing.

These new Windows systems are powered by Qualcomm’s Snapdragon X-series or Intel’s innovative Core Ultra 7 processors, also known as Lunar Lake. During CES, I had the chance to explore these systems that are quickly reshaping the landscape of mobile computing. With major PC manufacturers already releasing new models, it's clear this battle for power-efficient laptops is heating up.

In-Depth Battery Performance

For my hands-on experiment, I comparably configured both Lenovo models. The Slim 7i, with a starting price of $1,049.99, featured a slightly larger 14.5-inch display compared to the Slim 7x's 15.3-inch display priced at $799.99. Testing them both under 60% brightness, I discovered that the Snapdragon Slim 7x consumed battery power at about 10% per hour, promising around 10 hours of functioning time. Meanwhile, the Intel-based Slim 7i, with a slightly higher consumption rate of 12% an hour, provided close to 8.5 hours of continuous performance.

It’s evident that larger displays tend to use more power, impacting my experience with battery life across varying tasks.

The Trajectory of Tech Freedom

The essence of this technology becomes apparent when you realize the freedom of carrying just a single lightweight laptop without the constant search for power outlets. No longer do we have to be tethered to our desks or frantic about battery life during long meetings or commutes across bustling campuses.

My experience with the Yoga models has shifted my perception of portability; I hardly miss carrying around the charger anymore. These next-gen laptops truly embody the promise of ‘all-day use’ and could usher in a new era for working professionals.

Stay tuned as we continue to monitor the evolution of these remarkable devices in the ever-changing tech landscape where freedom and efficiency converge. At CES 2025, it’s clear that your days of worrying about battery life are over!
