LTE cellular connections are fast, but they use a lot of battery power because the LTE antenna is constantly scanning for an LTE signal — even if you’re on a Wi-Fi network. If your iPad battery is running low, you can switch to the slower — but lower-powered — 3G cellular antenna by following these steps:

1 Open the Settings app.

2 Tap Cellular. The Cellular settings appear.

3 Tap Cellular Data Options.

4 Tap Voice & Data. The Voice & Data settings appear.

5 Tap 3G. Your iPad shuts off the LTE antenna and turns on the 3G antenna.
