Battery saving/Low Power mode within OS discussions?

[sixwheeledbeast]

I have been looking into improving energy consumption recently. There's capacity to greatly improve the battery life from switching off features on a device. On my FP5 I can consume overnight ~30% battery with all features on, WiFi, BT, Location, NFC, 5G, device locked. Compared to 2% with only 2G enabled and device locked.

This has had me looking into shell scripts on the forum and the battery-saver app from open-store.
I'm looking for something light that would just disable all these features without going into each option and then restore everything back as I had it.

To me this seems like something that should be included into a toggle on the Battery pull-down menu itself, much like most modern devices have a "low power mode".
How feasible would a toggle option to disable all these power hungry features and set the radio to the most energy efficient available in your location. Then toggling back would restore what you had previous. It seems like something the OS should provide and not additional apps.

Is this something people would want to use from the OS itself rather than additional possibly more flexible unconfined apps?

I would say being part of the OS leaves scope for more battery saving options if it was to be taken further as the OS matures, maybe scheduler tweaks or manual display brightness settings for example. But keeping everything a simple toggle for the UX.

Something like this is already implemented in the OS. It is called "Flight mode"
Humour aside, I don't know if it is really worth implementing switch for turning off all but 2G when it can be done in two or three clicks. But if you want to contribute to Ubuntu Touch this way, you can take a look at how it is implemented in lomiri-system-settings repository.

I hoped this would have generated more of a discussion but maybe it's not something that people actively seek to use, despite being common function of most OS's?
I could argue it's not just a few clicks to do what I suggested, some are available in the battery page of settings but not everything.
I'd imagine the basics would be low hanging fruit for someone that understands QML and how those settings plugins work. Being around FOSS for a long time I know if your enable to bring pull requests to the table for your ideas it's much better but it's beyond my skills for the moment.
As I say functionality could expand beyond basics of toggling a handful of features I'm proposing now.
Would features that improve the OS like this be considered for inclusion into the OS rather than unconfined apps like battery-saver?
If in wouldn't be something of interest I'll likely look into something I can engineer, are there any documentations on controlling all of the settings options via a script beyond searching the forum for bits of code?

@sixwheeledbeast I think anything to save battery is good, especially for phones without inductive charging. Nord N10 lacks inductive, and constant recharging wears the port & battery. Works against keeping device a long time.

Something similar to Android's doze mode would be nice. I don't know exactly how it nice, but I think it could be possible to lower the CPU usage during periods of extended activity? I think there have been experiments with this before on Linux phones, like shutting down/disabling CPU cores when the phone is idle for a long period of time.
