Question Questions about using an old phone for WIFI / home use only

[balbasorus]

With my older, now SIM-less, phone I'd like to use for utility stuff, and I'm wondering if turning off the Mobile Data switch in the network & internet menu would cause other things to not work properly.

And are there other things I could turn off to save battery and resources since it will won't be used for anything but WIFI?

Welcome to the forum so you can just put the phone on airplane mode and then toggle back the Wi-Fi to connect.

You could turn off everything but wifi. IE BT, GPS,.
I do this with old phones, now it's a mini tablet.
You can also use it as a security camera /device.
Good luck

You can disable Bluetooth, NFC and background app refresh to cut idle power draw.
