[HowTo] Alternate way of saving battery when using 4G/LTE

AmauryDBZ

@lduboeuf sorry I didn't understand that the behavior of your hack was different from @lkroll's.

@lkroll Thanks a lot for your script, works like a charm !
As I said to @lduboeuf , I was wondering if it could be possible to add some exceptions ?
For instance, 4G could be maintained when the device is charging, or when hotspot activated, or even when an specific app is running (Futify for me).

Of course it should be possible but takes time. But would be better to look at the root cause, why LTE need so much battery. There are room for improvement, e.g we still don't manage the FastDormancy.

@lduboeuf I didn't knew about FastDormancy, make sense to priorise it.
Thank you for your answers and patience

Hi all,
[20.04 only]
I've made an app to allow to auto toggle LTE (4G) when cellular data is requested, and back to GSM (2G) when no data.

If anyone interested:
https://gitlab.com/lduboeuf/battery-saver/-/artifacts

source code:
https://gitlab.com/lduboeuf/battery-saver

the app can be closed after clicking "start" and if you see "Running...", it will create a background service

Edit: don't know if it is related but connectivity tends to have issue on upgrading to 4G. Or maybe only an indicator issue.

Would you release it on openstore ?
Is this for Xenial or Focal, or both ?

Maybe in the future, the ideal would be to have it integrated, but much much work involved + the fact that upcoming volTE will probably conflict with.

Focal only, only 24h a day

Hello @lduboeuf . When i saw https://open-store.io/app/batterysaver.lduboeuf , i thought first it was a GUI of this topic. Or could your app evolve towards this?

A bit different yes than always switching 2g/4g according tp screen state. But if i have 100 notif a day, it means 100 times the screen will turn on, i doubt it would be efficient...
But could be improved for sure

@lduboeuf Thanks for your new project. Well personally, in normal use, I generally completely turn off cellular data and activate it when necessary. I don't know how difficult it can be to develop, but I imagine an option that automatically turns on cellular data in case of one or more open apps or web-apps using it, and automatically turns off cellular data when apps or web-apps that used cellular data are all closed...
