Putting the daemons to sleep is gratifying, indeed.

These messages in the system log are NOT completely gone but mitigate that rarely appear again not solved but worked around, AFAIK. The problem is known from 4.4.0.68, at least - as you can read here.

These below, continues to pollute the syslog but I am investigating about them as well.

It is time that SFOS starts to honoring the OS postfix (aka became a serious Operative System - well, there are also few kernel OOPs to take care). Unfortunately my new smartphone arrived this afternoon and I have to move to another bay… 
UPDATE
The transaction failed messages are from ofono (pid: 2784). If killed, it re-spawns and start again to make such a show. Instead, activating the Android Support, it calms down.
Like already said, this thread is about the 10iii and not the 10ii. My cpus are all sleeping fine and i normaly don’t use bluetooth…and still i got the battery drain.
I suggest to change the title including the Xperia 10 II because, after all the two smartphones are enough similar to go with very similar settings.
This some information that are good for both the smartphone.
Please, install the System Monitor and check the system log with dmesg -Hw. Much probably you will see that your CPUs are not sleeping well but constantly awaken by contest switch (processes that switch the CPUs around).
As soon as, I will have the chance to buy a cheap Xperia 10 III, I will equipped my personal lab with that model as well. If you like to fund raise that buying, the link is here.
If you have read the thread, you would know that there are no sleeping issues on the 10iii. I just checked the dmesg log and there is nothing suspicious. Everything works as expected.
If your 10ii suffers from battery drain(the 6% per hour you wrote someehere) there must be something wrong wth your phone. I never heard of such a huge drain on the 10ii.
Since the 10ii and the 10iii don’t share the same Sony binaries and AOSP base they are not comparable.
If you still think that your drain is a generel problem and not only an issue on your phone/ your SFOS installation please start your own thread about the drainage on the 10ii and stop polluting this thread with nonsense.
Ok, thanks for the information.
While using the phone a 6%/h does not seem a problem for me. It is a 16h of working, even with 12% is about 8h of working. I have no experience about Android smartphone that can last much longer than this.
This is a very good point about hardware support and brings me to the idea that having a Xperia 10 III in my personal lab is a necessity in order to support it. Thanks again.

At first I was going to suggest including the Xperia 10 (and other Z80-based (1) designs) as well, since the those phones look almost identical, but then I had an epiphany.
We really should put everything in a single thread. Not only would this relieve us of updating thread titles, crossposting and being off topic would cease being possible at all. Unity, Mir (2) and understanding (3) will follow.
After all we’re here because of Sillfish Opera System and as you know Forum means city square in Latvian (4).
(1) That chip was designed by deflectors from the intel community in a story simliar to that of the 6502 A.D., but different
(2) …and, surely, the Snap package format and its related forum, Snapchat
(3) Please, just remember to sudo apt dist-upgrade regularly
(4) The citizens of ancient Vilnius who gathered in the square were not constrained by “titles” (5) set by anyone. We should follow their example and be equally free
(5) Titles were in fact bestowed upon the Caliph by God

@miau answered in a very consistent way:
AFAIK, this is the most significative difference between these two system apart 5G support and a different arrangement of the CPUs sets. At, least from a system admin point of view.
BTW, does the binaries package contain also the Linux kernel?
Differences include, but are not limited to:
- different SoC (Qualcomm SDM665 Snapdragon 665 11 nm vs. Qualcomm SM6350 Snapdragon 690 5G 8 nm, i.e. different CPU, different GPU, different modem, different technological process
- different AOSP binaries, different kernel version
- different battery (and probably the entire BMS)
- different other hardware components (display panel, camera module) and possibly also internal components like power circuitry, etc.
- software differences on the SFOS side, for example individually implemented VoLTE support for each of those models separately.
To recap, these two devices are actually almost completely different, with not much in common but the look. Any (or all) of the above can be responsible for different power consumption. These two devices are NOT comparable when it comes to power consumption. This thread is about the 10 III. If you want to talk about 10 II’s power consumption, please find (or start if it doesn’t exist) a separate thread about that model’s power drain.

Thanks @wetab73, I got your point.
However, from the PoV of a system administration those differences can bring different contributes and requires some adaptation in the shell scripting (eg. CPU arrangement 4:4 vs 6:2 or 2:6) but it almost the same old story:
- we need power saving templates (here).
When applying a pm template will be as easy as push a button or select an option and bush a button, then we can improve the templates. Improving both in generalization (policies) and in customization (smartphone models).
If this would not be possible, it means that the SFOS abstraction layer from the underlying hardware is not good enough (from the PoV of a system administrator).
Anyway, I am not interested in continue to write in this thread because I collected enough information from here. 
What we need is Jolla working on this. But there isn’t even a notice, nothing, they just don’t care.

It something that we can do by ourselves.
With all respect i have to say that i definitely have a sleeping issue with the Xperia 10 III, and it still happens every now and then. I described it earlier in this thread:
Seems like some process crashed and was eating up the cpu. If this happens again you could check the cpu usage and if a process is keeping your cpu busy. I wouldn’t call this a sleeping issue.
I have checked, and there is no process keeping any of the cores busy. Also from the attached screenshot (System Monitor) you can see there is no excess CPU usage during that period.
@direc85 commented my post and i think he has a point:

Sorry, i didn’t look at the screeenshot. I would call this a bug in SFOS charging system. If a charger is connected, all cpu cores are awake all the time. Seems like this didn’t go back to normal after you stopped charging.
For a few days my 10 III has been draining battery like crazy - but only on 4G network. 250-300 mAh of constant drain and NEVER GOING TO SLEEP, which results in 4-5% of battery drainage per hour. But that’s ONLY on 4G network (regardless of “4G calling” function status - switching it on or off does not make any difference). It makes no difference if mobile data is enabled or disabled, either.
If I switch the phone to “2G only” mode, or enable the Flight mode, everything starts working normally, i.e. power consumption drops to 100-110 mAh and when not used the device goes to sleep and consumes only 30-50 mAh. Switching to 4G mode instanly rises power consumption and causes that the phone never goes to sleep.
WHAT THE ****?
Hours spent on trying to find what’s causing the problem. I uninstalled everything that could possibly cause it, disabled all email accounts, tested it with other SIM card, looked for any processes with excessive CPU usage… to no avail.
One thing is clear - it happens only if 4G network is in use. The problem started all of a sudden, without any changes on my side and or new software installed.
T-Mobile Poland, nearly perfect network coverage, > 90% network signal strength.
Does anyone have any suggestions? Anything I could try to reinstall?
Reflashing did NOT help. When 4G network is in use, the device never goes to sleep, permanently draining at least 100-200 mAh, which results in 3-4% of battery drainage per hour. After switching to 2G network, as soon as the screen turns off, the device quickly goes to sleep and draws 35-60 mAh.
I have no clue what may be causing it. It happened about a week ago and since then nothing helps, not even a reflash.
On a different note, I’ve just discovered that 4G calling works only in the first SIM card slot. The same SIM card in the second slot can’t register for 4G calling…
