        @mario-ch Hello,
        what kind of connections are available in your case? I can help you to tweak the script for your needs.

        Anyway to take back the changes, remove both files:

        rm /home/phablet/lte-battery-saver
        rm /home/phablet/.config/upstart/lte-battery-saver.conf

          @c4pp4 As it seems, or rather I think 3G would work.

            @mario-ch You mean switch to 3G when display is off and switch back to 4G when on?

                @mario-ch Ok give me some time, I will test it on my xperia x and let you know.

                BTW you can try it on your own when you replace "gsm" with "umts".

                  @mario-ch In case of Xperia X (maybe it's related to Halium 7.1) we have to set it to "lte" option instead of "any", so the script for your needs (3G<->4G) is here:

                  #!/bin/bash
                  
                  interface=org.freedesktop.DBus.Properties
                  member=PropertiesChanged
                  
                  dbus-monitor --session "type=signal,interface='${interface}',member='${member}'" |
                  while read -r line; do
                          if [[ ${line} == *"com.canonical.UnityGreeter"* ]]; then
                                  read && read && read -r line
                                  if [[ ${line} == *"IsActive"* ]]; then
                                          read -r line
                                          [[ ${line} == *"true"* ]] && /usr/share/ofono/scripts/set-tech-preference /ril_0 umts 1>/dev/null
                                          [[ ${line} == *"false"* ]] && /usr/share/ofono/scripts/set-tech-preference /ril_0 lte 1>/dev/null
                                  fi
                          fi
                  done

                    which handles all the trouble when receiving MMS while cellular data is off

                    Hello. You done a huge work..! congratulations.

                    Does it mean that the main purpose of the work is that MMS could be received normally with cellular data OFF ?

                      No the purpose is to not loose MMS in any cases and being able to download them when data is back on.
                      You can't receive MMS without data on, no software tweak can change this.

                        It's not a story, it's a ''bible'' (which I hadn't read) like the amount of work (and surely headaches) put in by @jezek .. Yes, the aim is, rather, to have a delayed download (or to be able to delay downloading the MMS) when the cellular data is reactivated which is great. In short, the idea is to ensure that the MMS is not lost. I think it's more exact.

                        ....and this would be good as it would allow the cellular data to be turned off to save battery power and turned back on when needed to download the MMS. šŸ™‚

                          Hello c4pp4,
                          so, my device has been running with this customization for almost a week now.
                          Still, I can't say yet if it causes any improvement in battery life.
                          But for sure I can confirm that it does not contribute to any degradation.
                          Thank you again.

                            @mario-ch Maybe there is no such difference between G3 and G4 consumption.

                              I don't use the script but i can tell you that there is a big difference on my phone in battery consumption between 3G and 4G.

                                @c4pp4 Ok, so just to confirm (because I have already messed up Anbox and will probably have to reinstall anyway just for that), this script defaults to 3G/4G? So it won't go back to 2G? Because that's what I want. It annoys me to have to switch back to 3G/4G every time I turn my phone back on (2G is virtually unusable where I live but if the phone sleeps too long, it's back on 2G.) I only need the last script from before the "note for the further investigation" part? Just copy into a Seabass, save script and run in terminal?

                                NOTE: I don't care about battery consumption-- my phone is plugged in a lot-- but I do like my calls crystal clear when I dial without having to be like "ugh, it's on 2G again". Also, I can't get MMS on 2G but on 3G/4G, works fine.

                                  @totalrando use the walkthrough from the first post, just change variables to:

                                  primary_preference="lte"
                                  saving_preference="umts"

                                      @davedanger What version of UT? There is a regression when using 2G now.

                                          @davedanger I think it's Halium 9 device therefore it can be affected by https://github.com/ubports/ubuntu-touch/issues/1816

                                          Would you be more specific what you mean by "doesn't seem to work when put in upstart"?

                                            @c4pp4 I mean to have the script run at startup through either nano or chrontab @reboot. When I try "start batterysaver" after reboot, it says it's already running. I think the issue is on my end, because I've also tried running a vpn-autoconnect with the same results. It works fine when I copy/paste into the terminal, but when I nano or chrontab @reboot, the vpn switch automatically moves to "on" every 5 secs as scheduled but immediately fails and turns off. So I'm pretty sure the battery saver script is doing the same thing, trying to work but can't quite execute. Hope this was helpful.

                                              @davedanger The command "start batterysaver" starts upstart job after its created, after restart it starts automatically, you don't have to start it manually again - that's why "it's already running" message appears. If you see the "L" icon when the screen is unlocked and "2G" when locked, its working.
