Keeping your DJI Air 2S firmware up to date is one of the most important parts of maintaining the drone. Firmware controls how the aircraft, remote controller, battery, camera, sensors, transmission system, and many internal features communicate with each other. Because of this, firmware updates should not be ignored, especially if you fly your drone often or use it for travel, content creation, inspections, or professional work.
DJI firmware updates often include important improvements such as better flight stability, smoother control response, improved camera performance, updated safety features, bug fixes, battery management improvements, remote controller compatibility updates, and general system optimization. In some cases, an update may also improve connection reliability, reduce warning messages, or solve issues that pilots have reported after using the aircraft in real-world conditions.
The DJI Air 2S is a powerful drone with advanced features, including a 1-inch camera sensor, intelligent flight modes, obstacle sensing, and strong video transmission. To make sure all of these features continue working properly, the aircraft should run on the correct firmware version. The same applies to the remote controller and each Intelligent Flight Battery that you use with the drone.
Below is a detailed FAQ about DJI Air 2S firmware updates, including how to update the drone, what to do when firmware versions do not match, how to handle battery firmware, and how to avoid common update problems.
Why is firmware important for DJI Air 2S?
Firmware is the built-in software that allows the DJI Air 2S to operate correctly. It controls many important functions, including flight behavior, GPS communication, obstacle sensing, battery communication, camera operation, remote controller pairing, video transmission, and safety warnings.
When DJI releases a firmware update, it is usually designed to improve the drone in some way. Some updates are small and may only fix minor bugs, while others may include larger changes that improve overall performance or add compatibility with newer versions of the DJI Fly app.
Firmware updates can help with:
- Improving flight stability
- Fixing known bugs or system errors
- Improving aircraft and remote controller connection
- Improving battery communication and battery safety management
- Enhancing camera or gimbal performance
- Improving GPS or positioning behavior
- Adding compatibility with newer DJI Fly app versions
- Reducing firmware mismatch warnings
- Optimizing overall drone performance
For these reasons, it is recommended to check for firmware updates regularly. You do not need to update every single day, but it is a good idea to check before important flights, before traveling, after installing a new DJI Fly app version, or when the app shows an update notification.
How do I update the firmware of DJI Air 2S?
You can update the firmware of the DJI Air 2S in two official ways:
- Using the DJI Fly app on your mobile device
- Using DJI Assistant 2 (Consumer Drones Series) on a Windows or Mac computer
For most pilots, the easiest way to update the firmware is through the DJI Fly app. This method is simple because the app automatically checks the aircraft and remote controller once they are connected. If a new firmware version is available, DJI Fly will usually display a notification or update prompt on the screen.
To update through DJI Fly, first make sure your phone or tablet is connected to the internet. Then power on the remote controller, power on the DJI Air 2S, and connect your mobile device to the controller. Open the DJI Fly app and wait until the aircraft is detected. If an update is available, follow the on-screen instructions and tap the update button when prompted.
The app will download the firmware package and then install it on the aircraft, remote controller, and sometimes the battery, depending on what the update includes. During the update process, the drone may beep, the lights may flash, and the aircraft or controller may restart automatically. This is normal and does not usually mean there is a problem.
You can also update using DJI Assistant 2 (Consumer Drones Series). This method is useful if the update through the DJI Fly app fails, if your mobile internet connection is unstable, or if you prefer updating the drone through a desktop or laptop computer.
When using DJI Assistant 2, install the correct version of the software on your computer, connect the aircraft or remote controller using a USB cable, sign in to your DJI account if required, select the connected device, and choose the available firmware version. Then follow the instructions on the screen until the update is complete.
Before starting any firmware update, make sure:
- The DJI Air 2S battery is sufficiently charged
- The remote controller has enough battery power
- Your mobile device or computer has a stable internet connection
- The DJI Fly app is updated to the latest available version
- You are using the correct DJI Assistant 2 version for consumer drones
- You do not power off the aircraft during the update
- You do not disconnect the USB cable or close the update software
- You allow the update to finish completely before restarting or flying the drone
After the update is complete, restart the aircraft, remote controller, and DJI Fly app. Then reconnect everything and check whether any additional prompts appear. If no warning appears, the firmware update has likely been completed successfully.

Which update method is better: DJI Fly or DJI Assistant 2?
Both methods are official, and both can be used to update the DJI Air 2S. The best method depends on your situation.
The DJI Fly app is usually the best option for everyday users because it is fast, convenient, and does not require a computer. If your phone or tablet has a good internet connection and the app detects the update properly, this is the simplest method.
DJI Assistant 2 can be a better option when you want a more controlled update process or when the app update does not work correctly. It can also be useful if the firmware download keeps failing on your mobile device, if the drone is not updating properly, or if you need to refresh the firmware.
In general, use DJI Fly first. If the update fails, freezes, or does not appear in the app, try DJI Assistant 2 on a computer.
What do I do if the remote controller and battery firmware versions do not match?
If the firmware version of the remote controller, aircraft, or battery does not match, you may see a warning message in the DJI Fly app. This is a common situation and usually does not mean the drone is damaged. It simply means that one part of the system is not using the same compatible firmware version as the others.
Firmware mismatch warnings can happen after updating only one component, using a different remote controller, inserting a battery that has not been updated, or switching between batteries after a firmware update. Since the DJI Air 2S system includes the aircraft, remote controller, app, and battery, all of these parts need to work together correctly.
To fix this issue, update the firmware using one of the official DJI tools:
- DJI Fly app
- DJI Assistant 2 (Consumer Drones Series)
In many cases, the mismatch message appears because one battery has not been updated yet. If you own multiple batteries, insert each battery into the DJI Air 2S one at a time. Power on the aircraft, connect to DJI Fly, and wait for the app to check the firmware status. If the battery needs an update, the app should show a prompt.
Repeat this process with every battery you use. This is important because a battery firmware update is usually applied only to the battery currently installed in the drone. If you update the drone with one battery inserted, your other batteries may still need to be updated separately.
To avoid firmware mismatch problems, it is recommended to:
- Update the aircraft and remote controller together whenever possible
- Check every battery after updating the aircraft firmware
- Use only official DJI update tools
- Restart the aircraft, remote controller, and app after updating
- Do not remove the battery during the update process
- Do not close DJI Fly while the update is being installed
- Confirm that no firmware warning remains before flying
If the mismatch warning still appears after updating everything, restart all devices and check again. If the warning continues, try using DJI Assistant 2 to refresh or reinstall the firmware. In many cases, repeating or refreshing the firmware update resolves the problem.
Do DJI Air 2S batteries need firmware updates?
Yes, DJI Air 2S Intelligent Flight Batteries may need firmware updates. Battery firmware helps manage charging, discharging, power output, battery temperature behavior, safety protection, battery health reporting, and communication with the aircraft.
When DJI releases a firmware update that includes battery firmware, the battery installed in the drone during the update will normally be updated automatically. However, if you have more than one battery, you should check each battery individually.
For example, if you have three batteries and you update the aircraft using Battery 1, then Battery 1 may be updated, but Battery 2 and Battery 3 may still need the same update. When you insert Battery 2 or Battery 3 later, the DJI Fly app may show another firmware update or firmware mismatch message.
To update all batteries:
- Update the aircraft using the first battery
- Power off the drone after the update is complete
- Remove the updated battery
- Insert the next battery
- Power on the aircraft and remote controller
- Open DJI Fly and wait for the firmware check
- Run the update if prompted
- Repeat the process for every battery
This step is especially important for pilots who use the Fly More Combo, because it includes multiple batteries. Keeping all batteries updated helps prevent warnings and ensures that each battery communicates correctly with the aircraft.
Can I fly the DJI Air 2S without updating firmware?
In some cases, you may be able to fly without immediately updating the firmware, especially if the update is optional. However, if DJI Fly shows a required update, a firmware mismatch warning, or a safety-related update prompt, it is best to update before flying.
Flying with outdated firmware may increase the chance of connection issues, warning messages, app compatibility problems, or battery communication errors. If you are at home with a stable internet connection, it is better to update before going to the field.
If you are already at a flight location and the app suddenly shows an update prompt, consider whether you have enough battery power, enough time, and a stable internet connection. Avoid starting a firmware update in a remote location with weak signal, low battery, or limited time.
How long does a DJI Air 2S firmware update take?
The update time can vary depending on the size of the firmware file, internet speed, device performance, and whether the update includes the aircraft, remote controller, and battery. Some updates may finish in several minutes, while others may take longer.
The process usually includes two main stages: downloading the firmware file and installing it. The download speed depends on your internet connection, while the installation stage depends on the drone and controller.
During installation, do not interrupt the process. Even if the progress bar seems slow or the aircraft restarts, wait until the app confirms that the update is complete.

- Return-to-home altitude
- Maximum flight altitude
- Maximum flight distance
- Obstacle avoidance settings
- Control stick mode
- Camera resolution and frame rate
- Photo format
- Video format
- Gimbal settings
- Transmission settings
- Battery warning settings
Before doing an important flight, perform a short test flight in an open and safe area. Make sure the aircraft takes off normally, hovers steadily, responds correctly to controls, records properly, and returns stable information in the DJI Fly app.
What if the DJI Air 2S firmware update fails?
If the update fails, do not panic. Firmware update failures can happen because of unstable internet, low battery, app issues, USB cable problems, or temporary connection interruptions.
First, restart the aircraft, remote controller, and DJI Fly app. Then reconnect everything and try the update again. Make sure your internet connection is stable and that your devices have enough battery power.
If the update keeps failing through DJI Fly, try using DJI Assistant 2 (Consumer Drones Series) on a computer. Connect the aircraft or remote controller with a USB cable and attempt the update again. In some cases, DJI Assistant 2 may allow you to refresh the firmware, which can help fix update problems.
You can also try:
- Using a different USB cable

- Checking that the DJI Fly app is current
- Trying another internet connection
- Making sure the aircraft battery is charged
- Updating one device at a time through DJI Assistant 2
If the update repeatedly fails and the drone cannot be used normally, contact DJI Support or visit DJI’s official support website for further assistance.
Why does DJI Fly keep asking me to update after I already updated?
If DJI Fly keeps asking for an update after you already updated the aircraft, one of the most common reasons is that another battery still needs to be updated. Insert each battery into the drone and check whether the update prompt appears again.
Another possible reason is that the update did not complete fully. Restart the aircraft, remote controller, and app, then check the firmware status again. If the prompt still appears, run the update once more.
If the issue continues, use DJI Assistant 2 to refresh the firmware. This can help when the firmware version is installed but the system still reports an inconsistency.
Should I update the DJI Fly app before updating firmware?
Yes, it is a good idea to update the DJI Fly app before updating the aircraft firmware. The app is used to detect firmware versions, download update files, install firmware, and display system warnings. If the app is outdated, it may not detect the newest firmware correctly or may not communicate properly with the aircraft.
On iOS devices, check the App Store for updates. On Android devices, follow the update instructions provided by DJI or the update prompt shown in the DJI Fly app.
After updating DJI Fly, open the app again, connect the Air 2S and remote controller, and check for aircraft firmware updates.
Can firmware updates change my settings?
Firmware updates can sometimes affect settings, especially after major updates. Most settings may remain the same, but it is always safer to check them before flying again.
Important settings such as return-to-home altitude, obstacle avoidance behavior, maximum altitude, camera format, control mode, and safety settings should be reviewed after updating. This is especially important if you fly in areas with trees, buildings, hills, or other obstacles.
Do not assume that every setting stayed exactly the same. A quick review before takeoff can prevent problems during flight.
