Does anyone know what the "optimised battery use" setting does in the app?

I recently came across, via the ID Facebook group, a good explanation of this on the German meinid forum where they have one or two posters who post in a personal capacity but work for VW. A rough summary is:

The HV tops up the 12V when low regardless of whether this setting is selected, unless the car is faulty. The car will not allow the 12V to run low. This has been the case since early software updates (possibly 2.0 I think)
However, as well as the 12V having a total capacity, it also has a programmed energy 'budget' for each ECU. So if one ECU is taking too much power when the car is off (eg if you have walked past the car and activated keyless entry lots of times) the budget for that ECU may run out and the software prevent it from working. However, if you have selected this option that ECU's budget will be reset and the HV battery used to top up the 12V accordingly, even if total 12V energy content is not low. The function can then continue to be used. If optimised battery use is disabled, and in previous software versions without the option, I understand budgets are reset when the ignition is switched on.
It seems a niche use case to me, but if some function in your app or keyless entry isn't working, it might be worth turning on.

The 80% limit referred to above is called Battery Care mode, that's a different thing.

Never had this problem with my app (on a Google pixel phone). It works well 😮
Range always matches what the car says. It was a bit flaky when I first got the car but since a spate of app updates in spring/summer it has worked reliably, and the extra functions with 3.0 OTA all work well. The only ongoing problem is that the function to send a location to the car is still too slow to be useful.
Ok. So my app is on an iPhone.
Interesting you mention extra functions with 3.0. Such as? Or maybe again the IOS app isn't as good.
Car location in the map (when parked).
Car locked/unlocked status and window/door open indication on the main page.
Thanks. The only change I can see on the IOS app is a lock symbol:

Not sure I know what it does yet, but if it's supposed to show if the car is locked, it's wrong.
The iPhone version does seem to have more issues. In the android app the screen looks like this. The padlock symbol changes to open when the car is unlocked (after a few seconds). If any window, door or the boot is open, the view of the car changes to a grey scale overhead view with the open window/door/boot highlighted in red. Again after a few seconds.

The car's last parked location is shown in the map like in the picture below (I zoomed out so as not to giveaway my address but it's an accurate location).

I get the impression that most of not all of these issues that some people have with the app are down to its ability or otherwise to get up to date data from the car. Obviously these functions would struggle if communication is delayed. But most people I've seen reporting with 3.0 OTA are finding that they work well.

From reading various posts here, I get the impression that a Tesla is a computer on wheels, whereas other EVs are vehicles with a computer. Don't get me wrong, I'm not slating any vehicle and have no Tesla experience, just my own thoughts.
I quite like the idea of a used standard range model Y to replace my Octavia in a year or two if the prices are sensible, but if the ride is as bad as people make out my family would kill me. I heard rumours they were supposed to be improving it (think they came from a Musk tweet!) so interested to see what comes out. Although Musk himself also puts me off a lot.

Funny how we have got from the specific meaning of an option in a VW app to the pros and cons of Teslas.
