XC60 plugin hybrid in cold weather

I drive a XC60 plugin MY2022 (Eastern Europe) and I am bit confused about its behavior in cold weather. During warmer months, I was pleased with the pure electric range, which was consistently around 40km, even with AC on. However, this has changed drastically with the arrival of cold days. I usually precondition the car, using the feature of the mobile app (which only became functional after upgrade to 1.7), then at morning departure I activate immediately the hold function, thinking that this would lock and preserve the battery juice until later in the day, and also thinking that this would force the heating to be powered by the ICE. But this doesn't seem to work like expected: e.g. I start with an indicated range of 35Km, set the drive mode on hold, then during the first part of the drive I see the estimated range steadily decline, despite the lock indicator being on. So where does the battery power go, if I am running on ICE? Does the heating still take power from the battery, regardless the driving mode "hold"? Thanks for any tip or thought.

Is the battery gauge actually moving or does it stay full? If the gauge is NOT moving I assume the computer is re-calculating your battery range based off conditions.

I don't actually know how the PHEV batteries work as far as self-heating goes but it may be sensing a low temp and using battery power to keep itself warm but also letting the ICE top off the battery. So MAYBE you're using battery but it's also getting refilled or maintained. Just speculation.

lol I see this is 2 years old

When the ICE is stone cold, no matter what drive mode you are in or what you've asked the battery to do, the system will use a lot of EV power to keep the ICE's actual load to a minimum until it warms up a bit. Colder weather would exacerbate this in various ways, longer time for the ICE to warm up, less range available from the battery, more power used by the climate control system, etc.
