Dell Inspiron 14 Plus 7441 Review: Mainstream Snapdragon X Laptop Delivers Supreme Battery Life This Copilot Plus PC offers an unprecedented runtime inside all-metal design at an affordable price.

The OLED display on the enterprise-focused Dell Pro 14 Premium certainly looks great, but it's pricey and skimps on battery life. Will a package of peripherals help soften the blow?

The Dell 14 Plus 2-in-1 starts from $850, although Dell pricing varies wildly, and the base model of the three is currently $700. As reviewed, the MSRP is $1000, or $850 on sale currently.

The higher-resolution options tax the battery a bit harder, including the model that comes with tandem OLED, which Dell estimates to get just 14 hours in this same test.

The Dell XPS 13 2-in-1 (9315) expands the flagship line with a slim, gorgeous tablet packing impressive internals, albeit it with worse-than-average battery life.

Lenovo spoke of "multi-day" battery life, too, while both Acer and HP's sections of the Qualcomm presentation called out models running the Snapdragon X Elite chip with 26 hours of battery life.
