It’s important to clarify a core point first: Jumper is a Chinese brand that focuses on high cost-effectiveness.  Its products typically have impressive specifications in certain areas (such as screen and processor), but compromise on “hidden” aspects like battery life and overall build quality to control costs.

The official website may claim “Jumper EZBook X4 battery life of up to 8 hours” or similar, but this is usually an ideal test result under extremely low load (such as minimum brightness, local video playback, flight mode). Actual comprehensive battery life: In typical daily use scenarios (50% brightness, connected to Wi-Fi, web browsing, document processing, online video playback),
the actual battery life of the Jumper EZBook X4 is generally between 3.5 and 5 hours. High-intensity use: If performing multitasking, high-definition video streaming, or light programming, the Jumper EZBook X4 Laptop Battery<\/a><\/strong>life may drop to below 3 hours.
