WiFi/Mobile Data On/Off according to screen state?

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.

@yoni Have you looked at WayDroid? http://www.waydro.id/

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!

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!

You would also need to remove the battery but we all know by now that we can't expect that to be possible anymore...

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!

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

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.

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 ?

@yoni Your graphs show a lot of peaks and troughs but there is no indications of what or how high and low the readings are. 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.

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.

@yoni 5g is not already handled in Ubuntu Touch so you have time to test

@lakotaubp
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/cm².
I'm not a RF Engineer so pw/cm² 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:

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):

@keneda
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.
4G data on:

2G data on:

4G data off:
