Your iPad uses its built-in Wi-Fi antenna to constantly scan for available Wi-Fi networks, which brings two main advantages:

 You know the list of nearby networks is always up do date.

 It provides greater accuracy to location-based services such as the Maps app.

However, there’s also a big disadvantage to this constant network scanning: It drains your iPad’s battery. If you won’t be joining any Wi-Fi networks for a while, you can reduce the load on your tablet’s battery by shutting off the Wi-Fi antenna. Here’s how:

1 Open the Settings app.

2 Tap Wi-Fi. iPadOS displays the Wi-Fi settings.

3 Tap the Wi-Fi switch to Off. iPadOS shuts off the Wi-Fi antenna, disconnects from your current network, and no longer scans for nearby networks.

To resume the Wi-Fi thing, repeat these steps to turn the Wi-Fi switch to On.
