The 760mAh battery is the largest we've seen in a disposable. In Eco mode with moderate use (100 puffs/day), we got 1.5-2 days per charge. In Turbo mode with heavy use, expect daily charging. USB-C charging takes 60-90 minutes for a full charge, and the device can be used while charging.
Battery reality check: The battery will outlast the e-liquid in Eco mode — you'll recharge many times before the tanks are empty. In Turbo mode, battery and e-liquid deplete at roughly similar rates. This is actually well-designed: the 760mAh capacity is appropriately matched to the 18mL tank in Eco mode.
