Chromecast updates automatically, but you can check the status yourself
Chromecast updates on its own when it is connected to power and Wi-Fi. You do not need to do anything to trigger an update — Google pushes them to your device in the background, usually overnight or when you are not actively casting. The update process is automatic and requires no action from you.
If you want to check whether your Chromecast is running the latest version, you can look at the device settings through the Google Home app. This takes about two minutes and tells you exactly what version is installed and when it last updated.
Key Takeaways
- Chromecast updates automatically when plugged in and connected to Wi-Fi, so most users never need to manually update.
- You can check your current version and update status in the Google Home app under device settings.
- If an update is pending, restarting your Chromecast or leaving it plugged in overnight usually completes it.
- Older Chromecast models (first and second generation) may not receive the latest updates, but they continue to work with most casting features.
- Unplugging and replugging your Chromecast can force a pending update to install if it has been waiting for days.
How to check your Chromecast version in Google Home
Open the Google Home app on your phone or tablet. Tap the device icon in the top right corner, then select your Chromecast from the list of devices. Tap the gear icon to open settings.
Scroll down to the "About" section. You will see the current software version listed there, along with the date of the last update. If an update is available, you will see a notification at the top of the settings screen saying "System update available" or similar language.
If an update is waiting, you can tap the update button to install it right away. The device will restart during the process, which takes a few minutes. You will not be able to cast to it while it is updating.
What to do if an update is stuck or pending
Sometimes an update sits in a pending state for days without installing. This usually happens if your Chromecast lost power or Wi-Fi connection before the update finished. The fastest fix is to unplug the device from power for 30 seconds, then plug it back in.
After you plug it back in, leave it connected to power and Wi-Fi for at least an hour. The update will usually install during this time. You do not need to do anything else — just let it sit. If you want to speed things up, restart the device through the Google Home app: open settings, scroll to the bottom, and tap "Restart."
If the update still does not install after a restart, check that your Wi-Fi is stable and that your Chromecast is within range of your router. Weak Wi-Fi can cause updates to fail partway through. Move the device closer to the router if possible, or restart your router and try again.
Older Chromecast models and update limits
The first-generation Chromecast (released in 2013) and second-generation Chromecast (2015) stopped receiving major updates in 2020. They still work for casting video, music, and photos, but they will not get new features or the latest security patches.
If you own one of these older models, you can still check the version in Google Home the same way. The device will tell you if it is on the latest version available for that model, even if that version is several years old. Google does not force these devices to update further.
Chromecast with Google TV and Chromecast (3rd generation and newer) continue to receive updates regularly. These newer models will keep updating automatically for several more years.
Why Chromecast updates matter
Updates fix bugs that cause casting to drop, improve compatibility with newer apps, and patch security vulnerabilities. A device running an old version may have trouble casting from certain services or may disconnect unexpectedly.
You will not notice most updates — they happen silently in the background. But if your Chromecast suddenly stops working with an app you use regularly, an update is often the solution. Checking your version is the first troubleshooting step.
How to force an update if nothing else works
If your Chromecast has been pending an update for more than a week and restarting did not help, try a factory reset. This erases all settings and returns the device to its original state, then installs the latest version.
To factory reset, unplug the Chromecast, then hold down the reset button (a small recessed button on the back or bottom of the device) while plugging it back in. Hold the button for about 15 seconds until the light flashes. Release the button and wait for the device to restart. It will then go through the setup process again, and the latest update will install during setup.
After the reset, you will need to set up the device again in Google Home and reconnect it to your Wi-Fi. This is a last resort — try restarting and waiting overnight first.
Frequently Asked Questions
Can I turn off automatic updates on Chromecast?
No. Chromecast does not have a setting to disable automatic updates. Updates are required for security and compatibility, and Google does not allow users to opt out. You can only control when you manually check for updates through the Google Home app.
Will updating my Chromecast erase my saved networks or settings?
No. A regular automatic update keeps all your Wi-Fi networks, paired devices, and preferences intact. Only a factory reset erases everything. Automatic updates are safe and will not change any of your settings.
How long does a Chromecast update take?
Most updates take between 5 and 15 minutes from start to finish. Larger updates can take up to 30 minutes. During this time, your Chromecast will restart and you will not be able to cast to it. Once the update is complete, the device will be ready to use when ready.
Why does my Chromecast keep saying an update is available but never installs?
This usually means your Wi-Fi connection is dropping during the update process. Move your Chromecast closer to your router, restart your router, or restart the Chromecast through Google Home. If the problem continues, a factory reset may be necessary.
Is it safe to unplug my Chromecast during an update?
No. Unplugging during an update can corrupt the device and make it unusable. Always let updates finish completely, even if it takes longer than expected. If you accidentally unplug it, plug it back in when ready and let it restart on its own.
