But Airplane mode is no solution for me, because I am using the Pro1 not only as little computer, but also as a mobile phone.

Just to be clear, I wasn't suggesting not using a Pro 1 as a phone should be a solution for anyone. However, my defect led me to a diagnosis of the possible problem with Airplane Mode being a test. 🙂 I'm just lucky my problem doesn't affect me much because I happen to be weird.

my Pro1 was emptying the battery to only 50%. Slight improvement, but still to much to use it during the day at work and so on.

Last night I had "Airplane Mode" on and Wifi on too.  VoLTE (4G-Anrufe in the phone localized to a German UI) was on.

Could you please test if it make any difference over night, if you turn VoLTE temporarily OFF? Just to test if VoLTE is somehow part of the issue.
(I know turning VoLTE off will not be a solution, for carriers that shut down their 3G services. So just a test)

I will test it tonight with VoLTE off.

I used my Pro 1 with VoLTE off during the past 3 days. 

At nights I set it to "Airplane Mode" on and Wifi on. For this, VoLTE off made no difference regarding the battery drainage.

But during the day - with  "Airplane Mode" off and "normal" phone usage, VoLTE off reduced the battery drainage. It is still not as good as with Lineage 22.1, but my Pro 1 survived the days without additional charging in the afternoon. The past two days were weekend days, where my phone usage is different to week days. Therefore I have to observe this a few more days.

I also received a new 5G SIM card from my provider (I did not order this - they are changing their system - it is a pity, that the Pro 1 does not use 5G). I put the new SIM card in the phone today, because I have to use it before the end of the month. And I switched VoLTE on.

I will check for two or three days and then report here, if the new SIM card has an effect on the battery drainage. 
After that test I will continue with the VoLTE test.

Due to the changes @Hook reported here, I tried upgrading to 22.2 (again).

Will edit this post in some hours with the result....

ADD:  And it is completely USELESS!!! Went from 97% to 47% in short of 8 hours. (Idle overnight, as much as possible uninstalled/disabled,,,,)

Will go back to 22.1, or maybe stock and just forget about LineageOS, that (like the AICP project) seems to have F.. itself up to a useless state...
Went back to 22.1, though over four months old still much newer than Android 9 in stock....,

Spotted a more important bug that could be related with the battery waste as we discussed earlier.
With the same sim in the same phone at the same location, and set for LTE only, here VoLTE works just fine on 22.1, but not at all on 22.2.

So 22.2 CERTAINLY introduced some important bug in handling of carriers and bands (the sim is TDC in Denmark).
