How long does the G16 battery last?

“G16” can refer to different devices, so battery life depends on the exact model.

A safe rule of thumb:

• Gaming laptops like the ASUS ROG Zephyrus G16 or Dell G16: roughly 4–10 hours for light use, depending on the exact configuration, power settings, screen type/refresh rate, and brightness. Under gaming or heavy workloads, expect about 1–2 hours.
• Canon PowerShot G16 camera: commonly rated for a few hundred shots per charge on a full battery, with video recording lasting roughly around an hour depending on settings.

Battery life can vary a lot with brightness, refresh rate, Wi‑Fi, background apps, and battery health. If you want the exact number, check the official spec sheet for the full model name and year (for example, the specific ASUS, Dell, or Canon version). Exact figures can change by configuration and over time, so the official product page is the best source for the current rating.
