I live in a poor cell coverage area. I am retired so I spend a lot of time at home. I understand that the phone looks for a good cell signal and this takes more power from the phone battery. However, I have a perfectly good WiFi signal supplementing my phone at home. So why should the phone continue to expend energy trying to find a signal when WiFi is available?

Because Wi-Fi cannot be used to receive Notifications, Visual Voicemail, SMS texts and MMS picture messages. You also can’t make or receive phone calls unless you have Wi-Fi calling enabled with your carrier. If you can live without these functions you can turn on Airplane Mode, then turn on Wi-Fi if it goes off. That will stop the phone from searching for your cellular network connection.

iPhone 13. No cell coverage draining battery more than any other app.
