| Battery consumption | High | Average | Short |
| Stability | Average | High | Very high |
It's important to note that for AirPlay to work, the TV and phone must be on the same subnet. If you have a complex network infrastructure with guest Wi-Fi networks, make sure the devices aren't on different VLANs, otherwise they simply won't see each other.
Third-party sync apps
If built-in tools don't work or their functionality isn't sufficient, third-party apps can help. One of the most popular solutions is the app TV Cast or Web Video CasterThey allow you to stream video files, music, and photos, as well as open web pages on a larger screen.
