I’m looking for recommendations. I’d like to automatically turn off my cellular modem whenever I’m attached to a good Wi-Fi signal. Airplane mode on demand.

My rationale is multiple: I’d like to save battery life when I don’t need it. I don’t need phone calls or SMS. Everything goes over the internet for me anyway.

I would like to reduce my exposure to cellular security problems, and location tracking.

Ideally whatever implements this would be open source.

— edit ---- Using the word modem was probably wrong in the post. I want to turn the cellular features off. No mobile data, no mobile phone calls, no mobile text, I would like the cellular part of the phone to be powered off.

    For just the data. There is a developer settings “keep mobile data always active” something like that.

    But i think it made little difference for me in terms of battery drain so I leave it on.

    At the end, in my case after trying dozens of settings, battery drain for me is just handled by whatsapp and how crazily the app decides to start spamming the phone with wakelocks at certain times. Android/Google barely do something to cripple this app wakelocks.

      If you have a Pixel 6/7 or any phone that uses Exynos modem in general, it will make a noticeable difference in battery life. Simply because the modems are not as as efficient as the Qualcomm modems.
