Drone Battery Flight Time Calculator
Calculate flight time based on capacity and current consumption rate.

What is battery mAh capacity?
Milliamp-hour (mAh) measures battery capacity—how much current a battery can deliver over time. A 4000mAh battery can theoretically provide 4000mA for 1 hour, or 8000mA for 30 minutes. Higher mAh means longer flight time but also increased weight. Most consumer drones use 2000-6000mAh LiPo batteries, while professional models may use 10000mAh+.
Why does actual flight time vary from calculations?
Real-world flight time varies due to: wind resistance (headwinds increase power draw), payload weight (cameras, accessories), flying style (aggressive maneuvers use 2-3x more power), temperature (cold reduces LiPo capacity by 20-30%), altitude (thinner air requires more power), and battery age (older batteries lose capacity). Expect 70-80% of theoretical maximum in typical conditions.
How can I extend my drone's flight time?
Strategies include: reducing payload weight (use lighter cameras/gimbals), flying in calm conditions, avoiding aggressive throttle inputs, maintaining batteries properly (storage voltage, temperature), upgrading to higher capacity batteries (within weight limits), using propeller guards only when necessary, and flying at moderate speeds rather than maximum throttle.
What is a good current draw for drones?
Current draw varies by drone size: Mini drones (under 250g) draw 5-10A average, consumer drones (Mavic class) 10-20A, professional drones 20-40A, and large cinematography drones 40-80A+. Hovering typically uses 50-60% of maximum thrust current. Aggressive flying can spike to 2-3x hover current. Monitor your battery's C-rating to ensure it can safely deliver required current.
