The only answer I can give you I have already given you, and yes the electronics are not entirely unknown to me, about 50 years ago I took my exam for my radio amateur license.
But that knowledge is entirely hobby-based.
Indeed, you would expect that the battery used will last the longest of the device used, but on the other hand, you have no guarantee that all batteries will have exactly the same properties and lifespan from the factory.
So as I have already answered, a special navcore developed by the very famous Downunder, I do have a number of his on my server, but never immersed myself in this special one, and the only setting known to me is that of the battery saving.
I don't have the slightest idea how that is processed via the electronics in the devices of TomTom, the boot loader is nothing more than the BIOS in your PC and starts up all the hardware, possibly that the secret is located there.
Incidentally, there has been a persistent story in previous years that you can only upgrade that bootloader and never downgrade, that has been rumored for a long time and it is possible that what Downunder is writing about the exe file that, and then I have to guess, something changes in the boot loader.
What is certainly true is that if you are going to use a different navcore then pay attention to the file "system" which is the boot loader because if it is of a higher version than already installed it will be installed the first start which is not too bad but if at that moment you end up with an empty battery, you can use the TomTom as a bookend.
But even for that problem I once gave someone a indeed a special navcore including boot loaders, who later wrote that the device was working again, but it never became clear to me what state the device actually got into and whether the problem was caused by the failure of the boot loader upgrade.
Furthermore, I never worry about the battery, I never leave my GO 950 connected in the car, sometimes on the motorcycle my Rider v2, but it is in the backyard, it is from 2009 when I retired, I have I suspect that the full battery will last for half an hour, but for portable navigation I have my Galaxy S8.
I have sometimes wondered what the use is of a battery in those devices, in my opinion a button cell, just like in the PC, would have been sufficient to hold certain settings, only when such a device is used without on-board voltage it has its usefulness, but that's my thoughts on that.
Something completely different, I have a number of GoPro's, 2 old Hero 2 and 2 old Hero 3 plus a small Session for the helmet, even all those devices only have such a small battery that never last longer than about 45 minutes, now you may wonder why is there a battery that only lasts 45 minutes, in 45 minutes you can record quite a nice piece of video, but if I ride around on my motorcycle all day, that battery is not at all important , for the session I have a pretty large power bank in my pocket that lasts for more than 6 hours on a 64GB SDHC card, I thought, so here too my question, why should there be a special battery in there, they can never are large enough to provide the device with power for a day like the TomTom's
Best regards
