I had just posted the battery tests there and I hope that he would be kind enough to create a data on/off script if it is even possible.

All of the radio tests are 3 hours and they are represented by 10800 entries for the X values, and then the Y values represent RF density in pw/cmΒ².
I'm not a RF Engineer so pw/cmΒ² doesn't really mean much to me, but when I use Excel to view all of that data in graphs, it becomes easy to see the differences between devices, so here is the Xiaomi mi A2 UT with data on in grey, and the Pixel 4a 5G (using LTE) also with data on in blue and data off in orange:

Here is the same Pixel results, but with the mi A2 without a data connection represented in grey:
pixel-mia2.JPG
And here is how data off looks like for the Pixel in blue, mi A2 in grey and a Redmi 9 in orange:

So you can see that Xiaomi phones have more spikes and of greater energy, but I had seen far worse results with a Huawei Mate 20 Pro represented in yellow:

And here's again the first 10 minutes from the Pixel test:

and another graph of seconds 70 to 200, where background RF radiation is grey (no phone):

Not yet, first I need to check 3G and 2G connections with and without data. maybe GPRS works differently than LTE in the way that they handle a data link? I didn't actually test anything except 4G, also I didn't check 5G sub6 yet with my Pixel 4a 5G.
And I also want to conduct battery tests to be able to compare the differences, and that will take a couple of weeks.

Graphs without labels and scales on the axis make me a bit nervous as they can be used for and evidence of anything.
I'm not saying that is what you are doing or intending but it would help if the X and Y axis showed what was being measured. To strech the point you could be showing a high point of 8000 whatevers over a period of 8secs or a high of 0.8 whatevers over 8 years. One could be seen as insanely active the other the exact opposite.

That's amazing! It's not exactly what I was looking for, but it's definately the right direction.

So, did you ask @c4pp4 how to modify his script to make what you want possible ?

Those are only the perliminary results based on only one check with the data, and one without, and it seems that the push client is insainely radio active, and it is reflected on the battery.

But then you would not have power to run the app you ask about. You can't have it both ways.

I am not asking for any app but I can tell you the following :

  • I already had a Samsung Note II which had a removable battery in the time that I bought my BQ E5 HD Ubuntu Phone.
  • There are still some so called "Rugged phones" that have a removable battery! πŸ˜‰

So not all hope is lost : Just a lot of it! :grinning_squinting_face:

Wouldn't it be simpler to turn the phone off completely when you are not actively using it? Your EM radiation exposure would then be zero.

Actually that's not true! πŸ™‚

It looks like the back gesture is working so it might be a much better solution than dual boot, thank you for the idea, I'm definitely going to try it out!

I wish that UT was complete enough for all of my needs, but for me to be able to use the phone regularely, I need to use some apps on Android, and I really want to see how both OSs use the radio and battery.

  1. The hassle of turning the phone off and then on and then to unlock the device, is too cumbersome.
  2. That would make the phone useless for any incoming communications.
    I know someone who does that, but he is on the extreme of RF exposure prevention, he even uses the JRS router to reduce the signal strength and disable the beacons, but personally I still want to be reachable at least for calls and texts immediately, and for emails and IM I propose to have the data connection activated when the screen is turned on for a short while, regardless if the user didn't unlock the device, so that those communications could be retrieved, and there should also be a user defined windows of connectivity, so that it can be set to turn on the data every 5,10,xx minutes for lets say 30 seconds, and maybe even having the data only turning on depending on the proximity sensor so that it wouldn't turn on if it is in a pocket.
    Every person should have the ability to create a tailord scenario depending on their communication needs and exposure avoidance preferences.

There are countless studies that prove that mobile phones can, and can not, cause cancer and other medical issues, but I had never seen a study that shows that they have any medical benefits.
And the figure of 25 years of mobile phones being around should be evaluated with the massive proliferation of radio emitting devices, and also the amounts or signals being transmitted, that are exploding in numbers, especially since the iPhones and smartphones became prevalent in society about a decade ago, and then there are the smart home devices that didn't really exist a few years ago...
I'm waiting for a sim card to arrive so I can test UT's radio activity, and I hope that I'll be able to dual boot Android on it to see how the phone behaves on both.
I think that UT should have less activity due to the reasons that you mentioned, but let's wait and see.

I was not arguing with your intend to reduce radio exposition.
I just intended to share a music masterpiece your sentence made me think about directly reading it.

And of course, the modem does probably a bit of additional transmission when data is on, but that should also be not that much.

Also, there is no evidence now over more than 25 years that mobile radios can cause cancer in any way. By now long-term effects should be visible, but they arenΒ΄t. You also might want to read https://www.cancerresearchuk.org/about-cancer/causes-of-cancer/cancer-myths/do-mobile-phones-cause-cancer

I never cared less about the radios in my phone, until a friend lost his right ball to cancer, needless to say that from beibg his regular place of keeping his phone, he would never put it there again.
Am I saying that because he always left his phone in his right front pocket, that he got cancer in his right ball? I'm not. But since then I don't keep my phone in the front pockets.
Have a look at how it actually looks during those 3 hours, and the first 10 minutes for better resolution.

Using a RF meter and recording the total amount of radio activity over 3 hours.
Although I had carried the tests in the attick, and as far away from over radio sources, and the meter is not a professional one, I had trippled tested most of those phones and came with very similar results, so I'm quire certain that the results should be representative of what's really happening in regards to radio activity, and it makes sense that when mobile data is turned on, apps would comunicate with servers every so often, and that will account for the results.
