    @Linus67

    The long journey from a brand-new Commodore C64 with a thick book on DOS to a Pixel 3a running Ubuntu Touch.

      @Zer0 I hope you stay in touch with Ubuntu Touch.
      Just like Ubuntu Touch itself, there are several layers to the Ubuntu Touch community. You'll find the right people.

    • Powersave mode extrem

      My personal use of cell phones:

      • Calls + text messages: I want to be reachable at all times
      • I only use the browser, email, messaging apps, cloud services, and other apps when necessary (like a camera)

      Most days, the phone is unused for 90% of the time it’s turned on. So for 90% of my usage, even a Nokia 3210 (with up to 260 hours of battery life) would suffice.

      Task: Given this usage pattern, how can I maximize battery life?

      Workaround:

      Install and open “UT Tweak Tools”
      For all apps: Prevent background suspension = ON

      • Location services = OFF
      • Bluetooth = OFF
      • Wi-Fi = OFF
      • Mobile data = OFF
      • G2 network (optional)

      Then run the script in the terminal:
      ...
      #!/bin/bash
      #Enables power-saving mode on all CPU cores

      for governor in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do
      echo "powersave" | sudo tee "$governor" > /dev/null
      done

      echo “Power-saving mode has been enabled for all cores.”
      ...

      New scenario:

      • The phone enters deep sleep mode after a few minutes
      • You remain reachable by phone and text message
      • Set alarms and timers function normally
      • Power consumption drops to an incredible ~22mA (Pixel 3a)

      As a result, in this state, the battery level drops by only about 1–3% over a 10-hour period. (Tested on the Pixel 3a) Theoretically, a full charge lasts more than a week with minimal use. (see pritscreen)

      Advantage: There are hardly any restrictions. You can turn on mobile data or Wi-Fi at any time and use any app with an internet connection. Afterward, turn Wi-Fi and mobile data off again.

      Usage:
      With appropriate usage habits, this can be the default mode. The reduced processor performance is barely noticeable. Only launching apps takes 1–2 seconds longer.

      The cores can be restored to normal performance using this script.
      ...
      #!/bin/bash
      #Enables Schedutil mode (default) on all CPU cores

      for governor in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do
      echo "schedutil" | sudo tee "$governor" > /dev/null
      done

      echo “Default mode (schedutil) has been enabled for all cores.”
      ..,

      It would be perfect if a “super power-saving mode” like that could be built into UT.

      After clearing the saved Wi-Fi connections, power consumption is minimal.

    • RE: Call for testing: Ubuntu Touch 24.04-1.3

      I found the reason for my increased battery drain when using Wi-Fi.
      On January 26, 2026, I installed an app called "UB Connect" from the OpenStore. ubconnect
      I uninstalled it shortly after. The app wasn't uninstalled cleanly, and a ubconnect.daemon.service remained in the system.
      Whenever Wi-Fi was turned on, this daemon would automatically start, but it failed because the app was missing. This prevented Ubuntu Touch from going into power-saving mode after the screen was turned off.

      After uninstalling and deleting all leftover files from the ubconnect app, Ubuntu Touch goes back into power-saving mode with Wi-Fi on, and the battery consumption is minimal like with mobile data.

    • RE: I wanna go home

      I’ve been using Ubuntu Touch for four months. So I have no experience of older versions prior to 24.04.
      The frequently cited arguments that “users were unsettled by these or those changes” therefore don’t apply to me.

      My conclusion: Getting started with Ubuntu Touch was a bit bumpy, but I now really appreciate how it works. What I appreciate most is the app chain on the left-hand side. This efficient, unique selling point should definitely not be tampered with. Switching between apps is also brilliant. I don’t miss a home screen, desktop, etc. at all. Least of all do I feel the need for the interface to resemble that of Android or iPhone.

      I might have one wish: a multi-page app drawer (vertical or horizontal) or some other way of grouping apps rather than simply sorting them by name. Perhaps with horizontal dividers or spacing.

      I was monitoring the journal with “sudo journalctl -f” while I turned the Wi-Fi on and off. I noticed that when turning on the Wi-Fi, a connection attempt by the daemon fails.

      I tested on three Pixel 3a devices for one week. No active use. All background services turned off. Location services and Bluetooth also turned off.

      The same behavior occurred on every device. When I turn on Wi-Fi, power consumption increases dramatically.

      Without Wi-Fi: 1 to 2% per hour
      With Wi-Fi: 4 to 6% per hour

      @Futura Mobile network -> previous networks: Remove (forget) all networks and reconnect to your home network.
      This solved a few network issues for me.

      @gpatel-fr That´s perfect!
      Thank you very much for solving this stubborn problem.

      Now I can put the Pixel 3a into ‘Nokia 3210 mode’ with a single click. Calls and text messages work, and the battery lasts at least three days in this mode.

    • RE: wireguard kernal support on Ubuntu touch

      @dole583
      The WireGuard app works on my Pixel 3a. You can also follow these instructions. All you need is a working .conf file.

      Instructions from the UBports Forum

      Since you're familiar with computer science, setting up WireGuard VPN on the UT shouldn't be a problem for you.

      With the Pixel 3a and WireGuard, I have full control over my home network (OpenWrt, WireGuard VPN, Pihole, NextCloud....)

      There are also some fantastic apps with NextCloud support in the OpenStore.

      Livewire has ~200 MB Why is Livewire such a heavyweight?

      @gpatel-fr
      The issue with attachments not being forwarded only arises once you switch to 24.02.
      When you switch back to 1.3, the problem persists.
      In that sense, it could very well be an issue that was triggered by the installation of 24.02.
