The two top things you can do to improve battery life on your drone is to reduce weight, if possible, and adjust your flight habits, and avoid other mistakes. You may not be able to reduce weight on your drone, but most of us can learn to fly a little smoother and gentler. Rapid movements, flight at top speeds, and turbulent conditions eat more battery that you'd imagine. A drone at hover is constantly making micro-adjustments to stay in place, change to ATTI mode, or fly in slow circles, to reduce how much your machine is fighting to stay in place and level. Accessories are also a battery drain. For example, for our toy-class Syma X5C, we got around 5 minutes of flight while recording video and with prop guards installed, we bumped to over 11 minutes when we removed the prop guards and camera entirely. That was weight and power savings. LED lights are not a huge draw of power, but they pull power, adjust them if possible, remove them if not needed. Finally, for the long term, practice good battery management. Lithium batteries do not like to be stored at 0%, nor at 100%. Do not leave them plugged in at all times either. Keep cool and dry, and avoid unnecessary bumps. Physical damage is both dangerous, and bad for their ability to hold a charge.
