Any progress?

@applee
Both myself and @c4pp4 are using the same device, and @domubpkm also had battery savings using a Volla, there is something starnge happening with c4ppa's phone, and I'm really trying to understand why he is not getting any savings on 4G.

@applee
Those graphs represent RF activity with and without the data connection, so calls and texts are still available in both scenarios, and on the mi A2 the battery lasted 4 times longer when just the data is turned off, and this principle is the same on Androids and iPhones, but at different battery savings levels.
There might be something that is causing the cpu to constantly work, thus preventing battery savings, but UT definitely has control over the data connectivity, and it does turn it off.

@c4pp4
It definitely turns the data connection off, and it is visible when I checked it with a RF meter.
Data on (4G):

Data off (4G):

And it is the reduced transmitions that saves the battery, so your situation does not make sense.

@c4pp4
It just doesn't make sense. Could there be a script that turns it back on when you lock the phone?

@c4pp4
That is very strange, turning off cellular data should save battery by reducing the amount of outgoing radio transmitions, therefore what you are describing is contrary to all of the tests I had made on every OS, are you able to check that cellular data is actually turned off in 4G?

@c4pp4
Are you able to do some testing for at least 12 hours from a full battery to see the differences please?
And are you able to get the dBm numbers for 2G and 4G if possible please?
Are you using an email/IM (Dekko, Teleports..) client that works in the background?
I'm really preplexed that your'e not getting any improvements in battery life. this method had worked with many phones that I tested including iPhones using 4G.

@c4pp4
Can I also ask how did you conclude that there is no savings without mobile data on, was it during normal use? Are you able to check it during a 12/24 hour period when the phone is just sitting idle and untouched?

And thanks to @c4pp4 who made a script to accomplish my suggestion, you can try it out yourself and see if it works for you: https://forums.ubports.com/topic/6211/howto-alternate-way-of-saving-battery-when-using-4g-lte/

@c4pp4
If you have another Android or iPhone to check the signal strength with the same Sim that you use on your UT, there are apps that can show you the actual reception in dBm, so for me at home 4G is at around -90dBm and 2G is around -70dBm.

@c4pp4
Sorry for the late reply.
I didn't have time to check the script yet, and I'm quite surprised by your results, but I would like to thank you very much for your script!
Are you able to see the signal strengths of 2G and 4G in your area to see if that might account for the lack of battery savings?
As you could see in my test turning off the data in 4G quadrupled my battery life when I manually turned it off.

@c4pp4
I didn't mean flight mode, rather just to have the mobile data turned on and off accordingf to the screen state if possible, if not then according to the phone being locked/unlocked.
That will be so amzing if you can create such a script!

@ubportsnews
Are there any plans to implement a Doze like feature in UT to prolong battery life and reduce RF radiation?

@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:

@c4pp4
Hello c4pp4
I had made some battery tests to see how efficient your method is (I didn't actually use your script), and I had found that going down to 2G does increase battery life but that having the data connection turned off is actually more efficient, and I was wonderring if you are able to create a similar script that could enable/disable the data connection, preferebley without the need to actually unlock the phone, so that when the screen is turned on it will connect to the internet so that communications could come through?
I would had made one myself but I have no idea how to.
Here are the battery tests, starting with 4G with data on:

2G with data on:

And 4G with data turned off:

@klh
The ability to have a user defined sound for when a number is being blocked would be amazing!

@klh
I didn't know that UT supports UNIX, and it seems that the graph you posted is from that method, should I input all of those commands in the terminal to get that graph, and where will the svg file be saved?
And I'm assuming that I must create the file before the battery is completely drained, or will the data remain after the phone turns off and gets charged?
Should I change the size of the graph if the results are for a week instead of just 24 hours for the UNIX method?

@klh
What did you use to get this graph?

@arubislander @HUGEHEAD

Phones don't have room for a CMOS battery, and a quick look on OnePlus forums came up with a known time reset issue on the One model, is it a new issue since UB? does it happen if the phone is connected to a power source while it is restarting?

@falconer78
XDA is probebly the right place to get your phone prepared for UbuntuTouch, here's a guide:
