@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.

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.

@Zer0 said:

HomeSpike is a fullscreen home surface for Ubuntu Touch (Lomiri) that replaces "drawer-as-default" with what most people actually expect from a phone: a wallpapered home grid you land on after unlock, swipeable pages of icons, an iOS-style dock, and an edit mode where you long-press to drag icons around or remove them. New apps you install auto-add to your last page. The Lomiri drawer is still there (the patched long-press inside it gives you an "Add to HomeSpike?" prompt), but it's no longer the first thing you see.

I disagree with the argument: "....with what most people actually expect from a phone.

The current user interface design of UT is very good. It offers some suggestions for improvements to the organization of apps (divider lines, pages, spacing). Visibility of the status bar.

In the case of Ubuntu Touch, attempting to copy Android or iPhone concepts can only result in poor imitations. Nobody wants that.

@Zer0 I'm sure you're familiar with this initiative as well:

Issue #127€2000

Personally, I prefer this solution. Instead of sorting strictly by alphabet, it should be possible to create custom categories.

• Communication
• Development
• Tools
• News
• Education
• Games
• Favorites (fixiert) Like the iphon allway visible bar.

• A way to pin a Favorites category (at the top or bottom)

And if anyone wants it, a toggle (App Drawer as Home Screen always on)

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

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.

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

@Zer0
Absolutely no one will ever stick with Ubuntu Touch because it works similarly to an iPhone or Android device.
These people are also abandoning GrapheneOS even though it’s very similar to Android or iPhone.
To stick with Ubuntu Touch, it’s not enough to simply switch operating systems. It’s similar to Linux. So we should focus on the 5% of Linux users.
There are iPhone and Android people, Illy, Lavazza, BMW, and Porsche people. Today this, tomorrow that... Those aren’t real changes.
The only thing you can change in life is your mindset; the physical aspects will inevitably follow. Isn’t that exactly how it is?

@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.

@Keneda Please excuse me, but I’ve only been using Ubuntu Touch for about 4 or 5 months. So I’m still pretty new to it. I studied mechanical engineering—I’m not a Smartphone software engineer.
Anyway, my daughter wants to keep HomeSpike on her Pixel 3a (which is also the device I use for experiments).

@Zer0
My Windows partition is full of projects like that (solo efforts) from the last century. Some of them are even still running. I never got any credit for them.
If you really want to be successful, remember: “It’s incredible what you can achieve when you don’t care who gets the credit for it.”
I’m definitely looking forward to seeing the first drafts. At the rate you’re developing, that won’t be long now.

I had Windows decades ago... I have no idea how this will continue, please help me out. Otherwise I'll sell the thing again and it'll be a trip!

@fischer.poco You post random topics here from time to time in different languages, but you never respond to users' replies. What do you expect? A TeamViewer session?

@Keneda

Sometimes, such severe restrictions can also lead to a huge surge in innovation and creativity.
