Pine phone Battery life vs operating system
#1
Not sure how this could possibly be "Charted" so just going to post what I notice.

I happen to have 2 PMOS Convergent (3g ram) Pine phones.

One is running the factory install of PMOS

The other is running nightly build of Mobian OS   (Sept. 05 build)

Both at full charge, I did a few test calls and texts, short web connect
>>  then left idle with bluetooth and wifi turned off.

Checked after approximately : 12 hours

The PMOS phone was dead at  0% charge

The Mobian phone was at 30% charge

Maybe we can start to get a rough idea of what to expect for battery life.

Please do chime-in,  but for sake of continuity,  perhaps keep it in say 2 hour increments :
  2 hours - 4 hours - 6 hours - 8 hours 10 hours - 12 hours etc...
    Thanks !

Ive noticed mine (UB ports CE edition) runs flat in about 4 or 5 hours with UT. With Mobian it does seem to last about 12 on idle. Havent tested manjaro or arch as long which are my 2 others,  arch at least appears to have a similarly slower draw like Mobian

I am still attempting to get this in an organized fashion so any input is appreciated.

I have a no name old dumb phone for calling to & from and texting.
then a Brave Heart, 2 PMOS Convergent Pkg phones on hand, and a standard PMOS still on its way.
The Brave Heart is kind of a daily driver for now.

from my experience there doesn't seem to be any sort of consistency in battery life. some days it will fully discharge after 4 hours off the charger, and some days it can be in my pocket all day and still have 80% battery life.

running Manjaro

All day with 80% remaining sounds phenomenal. Outlier or not we gotta figure out what happened there and extrapolate that set up across all distros. Is Manjaro doing you well as a daily driver so far?

I find I get about 12-15 hours on my mobian braveheart - if I restart it after any significant activity e.g making or receiving  calls, web browsing on mobile date. lately it doesn't seem to require rebooting as often, but if I feel it startinmg to warm up in my pocket I reboot.
Ubports is all over the place, some days with low usage, it's at 63% after 10 hours then 5 mins later it's at 12%, which I presume is down to not properly sampling the battery on wake.

I notice sometimes when I pull my phone out of my pocket that the screen is on, which I think contributes to the lower battery life. my guess is the long life days have less or none of it.

yeah, I like Manjaro. I use Arch as my daily driver on all of my PCs, and Manjaro seems to be the most consistently updated of the Arch spinoffs here. I'm not a fan of Wayland, as it seems to crash a lot, but I'm even less of a fan of UBPorts or KDE, so it seems like the lesser of the available evils. if there were an X11 option, I would certainly adopt it at least to see if it's less prone to crashes.

I also think screen brightness in UT is a big reason for higher consumption. Looking at the screen is like looking at the sun, and the dimmest setting is still like staring at a light bulb. Cant wait for them to decrease screen brightness.

yeah, the autobrightness doesn't seem to work very well. it's either so dark that I can't use it in the day time, or so bright that I lose my ability to see walls at night time lol

if I manually set the brightness then it seems alright, but that's assuming that Wayland/Phosh are cooperating with me at that point in time. sometimes the entire Phosh UI becomes unusable, followed by a crash of Wayland, and a soft reboot. I wish that Phosh were written to be X11 compatible.

I honestly prefer the UI of Limiri or w/e UBPorts is, and it seems relatively stable, but it's a closed ecosystem so I may as well run /e/ if I were to run it, and Libertine seems a mess.

The battery life is one of my greatest concerns for PinePhone. I use Mobian with Phosh. The idle time is about 12-18 hours. I also observed that auto screen brightness doesn't work very well. However the option to reduce the brightness when battery level is low seems to work well. I usually keep the brightness at 50% and it is sufficient for me.

The greatest energy consumers seem to be:
1. Reboot takes 2-3 % of battery charge
2. apt update & apt upgrade (and generally heavy download via WiFi)
Unfortunately, after each update I feel necessary to reboot.

Also I often open Settings to enable/disable WiFi and check Sound input and output (they are suddenly reset to headphone instead of internal speaker / microphone after reboot). The starting / closing an application also seems to drain some battery charge, so I ended up with having Setting always started (I don't know any way to keep it minimized in Phosh though).

Overall, I am happy with the fact Mobian pushes updates for PinePhone hardware support and Phosh almost every day.
