What [automated] apps (or techniques) do you use to ensure radios are off? (This is not a question of manual techniques.)
For a variety of logically prudent reasons it may be useful to automatically turn some, each or all of our radios off, whether they are a. gps b. wi-fi c. cellular d. cellular data e. nfc f. bluetooth g. mobile hotspot h. nearby shares etc. (any others?)
The reasons for shutoff could be any one or all of these defensible basics:
Battery drain
Data charges
Privacy protection
Compute resources etc. (any others?)
What _automated_ apps (or techniques) do you use to ensure some, most, or even all your radio transceivers are automatically turned off when unused?
"c. cellular" and "d. cellular data" are ONE TRANSCEIVER.
"g. mobile hotspot" is not a transceiver. It is a system services that makes USE of the WiFi transceiver; assuming that you're not using it via USB (on an iPhone at least).
"h. nearby shares" aren't transceivers on your device.
Poor, little Andy (Arlen et al) had to create a brand-new nym just for this post... Such "adult" behavior! Also, gotta love how his little troll script mangled the new nym:
You're the one saying tin foil is required to turn off a phone radio. What kind of phone do you have that you can't control its radios anyway? How do you automatically turn off those six main radios on _your_ phone?
the iphone probably can't do anything like it but people should be able to find android hardware utilities to do what is asked with all kinds of user preference switches based on time of day or inactivity period or whatever
of course it can, however, turning off the radios of a mobile device greatly reduces its functionality.
normal people want their phones to actually do stuff versus being a non-functional brick in their pocket, with all modes of communication having been disabled.
paranoid lunatics, on the other hand, likely have other ideas.
You're asking the wrong question. What you really need, before you can turn off various communications devices in your smartphone, is a means of verifying that they're actually turned off. Using apps and settings on the phone are not sufficient because they often lie. For example, turning on airplane mode probably does disable all the major transmitters in the phone. The transmitters can easily be turned back on in the settings app, but the phone will still indicate that it's in airplane mode.
What you need is something like a spectrum analyzer that will show everything from 13.56MHz (NFC) to the highest frequency in the 5G cellular band, 39GHz.
13MHz to 1.7GHz can easily be done with a minimal RTL-SDR receiver.

There are ready to use spectrum analyzers suitable for detecting if your phone is transmitting. For example:

Don't worry about lousy sensitivity. The spectrum analyzer will be very close to your smartphone and should indicate if there's any RF being belched by the phone.

Unfortunately, there are some 4G frequencies between 1.7 and 2.2GHz that the commodity spectrum analyzer can't see. Also, the various microwave 5G frequencies are not covered. It's possible to build a better SDR (software defined radio) spectrum analyzer that does it all, but it will probably cost more than you want to spend.
Anyway, once you have a way to confirm that your phone is not belching secret messages to the dark lords running the evil empire, you can ask about and test automated apps that will insure your phone's silence.
Really only four now: • Cellular Data (it's all data now, for the most part, at least in most developed countries) • Wi-Fi • Bluetooth • GPS (receiver only)
For GPS you can't really turn it off. On Android you can spoof your GPS location if you don't want your location to be tracked.
I read one thread on Reddit where someone tried to automate turning off the radios using Tasker but was unable to accomplish this on an unrooted device.
