I can't find the link now, but there was a recent report that the PinePhone was getting 12 hours on standby ...I do hope that is with the modem running, so that it can receive calls!


I saw that on twitter as well. A Danish programmer was able to shut off
3 of the 4 cores in the arm processor and that extended the life of battery
from 10 to 12 hours. I assume that the phone would be in some type of sleep mode with one core working .
It would wake up if a phone call occurred.

Here's report
Quote:
Marius from UBports has started experimenting with having the kernel downclock the core frequency, drop the CPU voltage and turn off 3 cores when the phone’s display is off (in its idle state). This early experimentation has resulted in a stand-by time of approximately 12hrs, which is rather impressive for a first battery-preserving attempt. This will only get better with time, as it becomes paired with more advanced power management.

First attempt = 12 hours of stand-by time ... I like that.

Latest news of pinephone development...

But what’s more important is that Manjaro ARM for PinePhone now supports phone calls, and that right there is a great example of the amazing work the Open Source community can do.

UBPORTS blog has interesting info about adding an external monitor to the pinephone.
This could turn the pinephone into a regular computer.

PinePhone and external display support
PoVoq asked whether the PinePhone will be able to support use of an external display, as current devices do? The answer is yes, support will come eventually but a lot of software needs to be built for that and of course for us getting the PinePhone working well as a phone is our first priority. Extending external functionality will come later. The way things work with existing devices in still not as smooth as we would like and we need to apply improvements across the whole range of them. Libertine is another area where we need to see improvement but again this involves all our devices, not just the PinePhone. A supplementary question was whether legacy apps on the PinePhone were already working better in some respects than other devices. It isn't yet but we are quite clear that it will eventually. It is a simple fact that Xwayland works better than Xmir, so in the end the PinePhone build will be superior for running arbitrary legacy apps.

I think it is all a bit crazy. We already have regular computers but some had long term dream of having their favourite OS on their phone. But Google took Linux and their research presumably informed them that standard Linux wasn't a good fit for a small phone device; hence they created Android, which works (problems being more a result of Google control and advertising/constant-updates etc). As others said you can run standard Linux (e.g. Debian) in a chroot and, my goodness, you can chromecast to as big a monitor as you like, and... your phone may not need charged every 6 or 12 hours!!!

Having said that, development for development's sake is a good thing too, in my opinion - it may not yield the most usable products, but a lot is always learned in any attempts, which informs other more practical projects later.

One possible problem I discovered from Maru OS project ...

When using external monitor ---> the phone can't be recharged!!!!
If they don't fix that problem then the user will be angry.
