Razer Blade 16 battery life lasts several hours longer with Intel instead of AMD

Battery life for the 2025 Razer Blade 16 is pretty good especially for a gaming laptop. We are able to record a WLAN runtime of almost 8 hours when set to 150 nits, Balanced mode, and Automatic Graphics or iGPU mode. In comparison, most other 16-inch gaming laptops have a tough time cracking the 6-hour mark including the Lenovo Legion Pro 7i or HP Omen Max 16 when under similar conditions. For 2026, Razer has updated the Blade 16 from AMD Zen 5 to Intel Panther Lake for even longer battery life results.

As detailed in our review of the unit, the Intel-powered Blade 16 can last for almost 12 hours of constant WLAN browsing to be almost 4 hours longer than the AMD-powered Blade 16. The improvement is mostly attributed to the Intel CPU as power consumption when idling on desktop can be as low as 4 W compared to 11 W on the AMD Blade 16. Thus, the new 2026 Blade 16 tends to be more efficient when running lower workloads like web browsing or word processing.

Our independent battery life measurements are also surprisingly close to Razer's advertised claims. The manufacturer states a "Modern Office" runtime of up to 13 hours and 8 hours for the 2026 Intel Blade 16 and 2025 AMD Blade 16, respectively, which is only 1 to 2 hours longer than our recorded results.

Panther Lake comes with several other benefits over AMD as well including faster gaming performance, cooler core temperatures, official Thunderbolt 5 support, and faster memory. We recommend checking out our full review on the 2026 Blade 16 to learn more about this year's upgrades.
