If your Chromecast has been buffering a lot, this post will show you likely reasons why and what you can do about it.
Why is my Chromecast buffering a lot?
Often, the cause of Chromecast buffering a lot is nothing to do with the Chromecast itself.
Rather, it is usually an issue with things such as trying to stream video despite having a bad internet connection, using an unsupported app or because the device is running low on ram.
Below are likely reasons why your Chromecast is buffering.
Your device is occupied with other processes
While mobile devices are very powerful these days, there are still things that can result in them slowing down including streaming to Chromecast.
If there are other processes running on your phone, it could be the case that they are causing phone’s cpu to be busy dealing with them. It might also be the case that they are taking up your phone’s ram.
It would help to try closing any apps that you are not using and to see if that allows your Chromecast to be less laggy.
If you are trying to stream something from the internet, it could be the case that there is an issue with your wifi.
This would be more likely if it is laggy even when you are trying to stream things such as videos directly to your device.
In this case, it would help to see if you can improve your internet connection such as by moving the wifi router closer to you or by using an ethernet adapter.
Alternatively, you could try streaming at a lower resolution or you could download the content to your device before streaming it.
There is an issue with the device you are using
It might be the case that there is an issue with the device you are using and that there is actually no issue with the Chromecast itself.
This would be more likely if the video is choppy even when you are not streaming to the Chromecast and you are looking at it on the device.
In this case, it would help to try things such as lowering the resolution that you are streaming.
There is an issue with the connection
It could be the case that there is an issue with the connection of your Chromecast and your device. Possible issues could include:
- Charging the Chromecast via USB instead of from a power socket. It might be the case that the USB port is not providing the Chromecast with enough power.
- The HDMI cable is not plugged into the TV correctly or there is a problem with the HDMI port
- You need to restart your Chromecast and reconnect it to your TV as well as your device that you are streaming from.
You need to disable the “Use 50Hz HDMI Mode”
Some users have found success by disabling the ”Use 50Hz HDMI Mode”. You can do this by opening the Google home app and then going to your devices, then click the 3 dots on the top right then click settings.
You are trying to screen mirror the wrong things
Screen mirroring requires your phone to encode the screen then to send it to the Chromecast.
This is fine for things such as presentations, but it does not work so well for video because the video must be decoded then encoded for the Chromecast by your phone.
Instead, it is better to cast the video directly to the Chromecast.

- Change your Wifi to be 5 Giga Hertz, you can find tutorials for this online. This allows your wifi to transfer more data per second.
- Factory reset the Chromecast. While the device is plugged into the TV, hold down the power button for around 25 seconds. The device would flash red, then white. Once it flashes white and your TV goes blank, release the button.
