You’re right about the SoC. I think it’s just not possible or worth yet for a company like Purism to create new standards that we can change parts on it like on desktop motherboards. However, don’t forget that is not the only thing that matters.
Regarding power usage:
Sadly true. Okay half true. Modern CPUs are all using some kind of low power abilities like reducing clock rate. But at the end it’s designed for automobiles where battery is no big deal for a simple board computer and low power profiles are just nice to have, but no requirement.
OS is optimized, but still has much space for further improvements. They already spend a lot of time to extend the time from 6h max usage to (dos spoke about) 24h. Google and Apple have just much more work done, yet and that’s what we can see in the results. Nevertheless we may see further improvements on our GNU/Linux mobile devices (also related to Pinephone, Tablets etc). The process for further improvements may just slow down since things become more complicated.
You simplify this. Its odd and more complex. Because of the Kernel, the Hardware and it Power Saving Functions.
In the early Linux Days, power Saving was protected and it was hard and need much time to re-implement that feature for usual PCs.
The same we see here too. If you like take a deep look into hibernation.
TuxonIce can be some Key. But for Librem5 it have to be special. Since you would like to have a basic Process that run and wake up when you receive important interactions.
And that are not just Phonecalls and SMS. Its too:
Wake Up Timers/Alarms.
Message for Battary with lower than 5%!
Important SMS Broadcast Messages
Push-Messages from your Favorite Focuse Apps.
Sleep but just Play my Music/Podcast from RAM.
Collect GPS Information, if GPS is active.
Yes thinks like that should be done in Background if you Phone reach a low Level of Sleep.
However, i turn my phone off if i do not need it or WLAN and Mobile. However Using Mobile Data needs less energy here than my WLAN. Think its because WLAN is not optimized, and maybe the Mobile Access too.
To gain the last percentage its hard to focus on that drivers i think because they may be proprietary enhanced, claimed by patents.
But we can find and evolve some better with time and enough nerds, like to focus on that kind of computing to understand it and enhance it.
Apparently Flx1 phone which also runs phosh and has better android integration has much better battery life than Librem 5 and even supports 5G . Some users even state that it can last days and with moderate usage can easily last a day at least . And this comes also from a small development team . So it can be done , they have prove it. I do hope that Crimson brings improvements to the battery management department
Crimson will not bring such improvements. It’s no magic that glibbers inside your device. As I said somewhere else, Mobian also has not such a long uptime, so Crimson will neither.
And why 5G? For what do you need it right now? I think we have other things on the todo-list with much higher priority. Once 5G becomes important, we still can upgrade the L5.
I m sorry I meant that even with 5G which consumes more battery than 4G. I really don’t need 5G in my case not even 4G to be honest as 3G is still perfectly usable here
