How to Fix Performance Issues on a DJI Phantom 4 Pro

Introduction

In This Guide
You'll Learn How To:
  • Improve the performance of your DJI drone.

1 Safety First

As with all Drone flying, please keep the following in mind:

  • Make sure you are properly registered with the Federal Aviation Administration, or qualify to fly without registration.
  • Make sure you have permission to fly from the person or group that owns the land you'll be over.
  • Make sure you are in-touch with the control tower before flying near an airport.
  • Make sure there's no obstructions, such as power lines or trees, above your flight area that could cause problems.
  • Make sure there's no one below your flight area that could be hurt.
  • Make sure you are not near government infrastructure or other sensitive properties.
  • Make sure the weather is safe to fly in.
  • Make sure you keep your drone in your sight at all times, and get help from an observer if necessary.

2 Toggle Flight Mode

The DJI Phantom 4 drone has three selectable flight modes you can choose from, including one that the drone will fall back to in certain circumstances. Each of these flight modes affect the drone's behavior and performance. Understanding them can help you select the right mode for the environment you're piloting the drone in and prepare you for potential performance issues or hazardous situations. The three flight modes are:

  • P-Mode (Positioning): P-Mode is the standard flight mode for the majority of pilots. In this mode, all the sensors on your drone are active, including GPS and any available vision or infrared sensors. This results in precise hovering of your drone, even if you stop controlling it with the remote control. P-Mode requires a strong GPS signal to function and will disconnect if lost. This mode is best for safe flight and navigating between obstacles. Large stick movements must be made on the remote control to achieve high flight speeds.
  • S-Mode (Sport): S-Mode is a more advanced mode of flight. In this mode, the drone uses only GPS signal for positioning. While this increases the available speed of your drone, obstacle sensing systems are disabled. As such, the drone is unable to sense and avoid obstacles on its own. S-mode is designed for agility and speed in the air, making it more responsive and sensitive to stick movements. This means a small stick movement on the remote control translates into a large travel distance of the drone. Maximum speed, descent speed and breaking distance are significantly increased. Greater care must be taken when flying in this mode.
  • A-Mode (ATTI or Attitude): Your drone will enter ATTI Mode when the vision systems are disabled or unavailable and either it loses GPS signal or if there’s compass interference. ATTI mode is designed only to maintain the altitude and attitude of the drone and does not use any GPS or vision systems. Therefore, this allows the drone to drift and move in windy conditions and needs to be carefully controlled manually.

To manually select the flight mode you wish to pilot the drone in, slide the flight mode switch on the left shoulder of the remote control to its respective position.

By default, the drone will be locked in P-Mode regardless of the switch position. In order to manually switch between flight modes using the switch on the remote control, Multiple Flight Modes must be enabled within the settings of the DJI GO 4 app. Here's how to do it:

  1. Launch the DJI GO 4 app on your mobile device.

  2. Select the menu (three dots) in the top right corner.
