Lenovo’s 975g Yoga Slim 7i makes battery life its biggest performance feature

Lenovo’s premium Yoga Slim 7i trades sustained peak power and ports for a 975g design, more than 16 hours of battery life and a high-spec OLED display.

Lenovo’s Yoga Slim 7i makes its case through restraint rather than excess. Weighing 975 grammes, with a 75Wh battery and a 16-core processor inside, it is designed to be carried, opened and used for long stretches away from a desk. According to Panorama, that balance of lightness, endurance and performance is the defining idea behind the machine.

The review unit tested by the magazine used an Intel Core Ultra X9 378H, paired with 32GB of LPDDR5X-9600 memory and a 1TB SSD. On paper, that specification places it firmly in premium territory. In practice, the slim 13.9mm chassis cannot sustain the chip’s highest power levels for long, so Lenovo has accepted some limits in continuous performance. That trade-off is deliberate: the model is aimed at demanding users who value mobility and battery life as much as raw speed.

That does not make it underpowered. Panorama says the Intel Arc B390 graphics with 12 Xe cores leaves enough headroom for smooth everyday work and some gaming, while the machine still feels responsive in office tasks, media playback and lighter creative editing. The broader point is that this is not a laptop built to replace a desktop workstation; it is a portable system that tries to preserve enough performance without compromising its main advantage, which is ease of use on the move.

Battery life is one of its strongest claims. In mixed testing that included office work, video playback and some editing, Panorama reports that the 75Wh battery exceeded 16 hours. The 65W USB-C charger is compact enough to forget in a bag, which reinforces the sense that Lenovo has optimised the device for travel and day-long use rather than for plug-in permanence. The 14-inch OLED display also helps the experience. It offers a 2,880 x 1,800 resolution, a 120Hz refresh rate, touch support, full P3 colour coverage and a quoted HDR peak of 1,100 nits. Glossy finishes still show reflections and fingerprints, but the Eyesafe certification, flicker reduction and lower blue-light output are intended to improve viewing comfort.

The rest of the package is similarly ambitious, if not entirely compromise-free. Panorama says the Yoga Slim 7i has passed MIL-STD-810H durability testing, includes Wi-Fi 7 and carries a 50 TOPS NPU, which qualifies it as a Copilot+ PC. There is also a 5-megapixel webcam with infrared support for face recognition, plus an electronic privacy shutter. What is missing is more telling: there is no fingerprint reader, no stylus support and only three USB-C Thunderbolt 4 ports, with no HDMI, USB-A or headphone jack. That forces some users to rely on a dock or adapter.

The styling is distinctive, too. Lenovo’s Seashell white magnesium-and-aluminium finish gives the notebook a cleaner, less anonymous look than the usual office grey, although Panorama notes that it marks more easily than expected, especially on the keyboard. The bigger obstacle is price. The reviewed configuration costs €2,699, with the range starting at €1,982. That places it in a selective part of the market, where rivals may offer stronger value on paper. Even so, Panorama’s conclusion is that the Yoga Slim 7i stands out because its portability and stamina are not abstract selling points; they are the features that define the entire product.
