Does cold weather affect drone battery life?
I want to fly my drone this winter for some snowy landscape shots and I have heard that cold weather kills battery life. How bad is it really and what can I do to protect my batteries and get the most flight time possible in the cold?

Cold weather dramatically reduces LiPo battery performance. At 0 degrees Celsius you can lose 30 to 50 percent of your rated flight time compared to flying at the ideal 20 degrees. The electrolyte chemistry inside the cell slows down significantly, internal resistance rises, and voltage drops under load far faster than the battery percentage indicator suggests. This creates a dangerous situation where the drone can cut out unexpectedly even when the app shows 30 percent remaining.
The most effective countermeasures are simple. Pre-warm your batteries indoors before you leave and keep them in an insulated neoprene battery pouch during transport to the flying site. Once on site, do a slow warm-up hover for 2 to 3 minutes before doing any demanding maneuvers. Always watch the voltage per cell reading rather than just the percentage in cold weather. Bring extra batteries and land earlier than you normally would.

A simple trick I use is to keep spare batteries tucked inside my jacket between swaps. Body heat alone is enough to maintain them at a usable temperature. The difference in flight time between a cold battery pulled from a bag and a warm one kept against your body is easily 5 to 8 minutes.
I fly in Scandinavia regularly and this habit has saved me from a lot of frustrating short sessions. Combined with a good insulated case the body-warming method is cheap and effective.

DJI drones have a battery self-heating feature that activates automatically when the battery temperature is below about 15 degrees Celsius. You will see a warming icon in the DJI Fly app. Do not launch immediately when this shows up as the heating process uses power and the motors under full load with a cold battery is risky.
Instead, hover at low altitude for 2 to 3 minutes before flying normally. This lets the battery reach operating temperature through its own heating element and through the heat generated by normal flight loads. Starting aggressively from cold is a recipe for a sudden power dropout.

The biggest cold-weather danger is voltage sag causing an unexpected low battery cutoff before the app percentage shows anything alarming. I have seen drones drop out of the sky at 28 percent indicated because voltage sag in cold conditions triggered the safety cutoff.
My solution is to set the return-to-home battery threshold higher in winter, around 35 percent instead of the default 25 percent. This gives a larger buffer for the voltage variance that cold temperatures create and ensures the drone has enough power to make it safely back.

One critical point that gets overlooked: never charge a cold LiPo battery. Let it warm to room temperature first before connecting it to the charger. Charging a cold LiPo causes lithium plating inside the cell, a process where lithium metal deposits on the anode rather than properly intercalating into the electrode material.
Lithium plating permanently degrades capacity, increases internal resistance, and in severe cases creates internal short circuit risks. After a cold weather flight session, bring your batteries inside and let them sit for 30 to 60 minutes before charging. This protects your investment significantly.
