Battery drain on XA2 when not in flight mode

I used LineageOS (an Android distribution) and the battery would last +7 days, so the battery is still good.

So, I got the logs of ofono with 4G enabled and with 2G. There are much more logs with 4G.
The logs with 4G contains a lot of these:

Can't parse modem-handled proactive command

I tried with the most recent ofono from upstream and it cannot parse the input either, so I’m assuming the data is just plain wrong.

Does any of you have this error in their ofono logs?

I’m not sure yet where the input comes from and if we have control over it, but I’ll continue my investigation.
