Someone else's PW3/2015 model.

Battery life was very poor.

No WiFi (Aeroplane mode) and display of adverts was blocked by replacing a directory (folder) with a file.
So I swapped it with my newer PW3/2015 bought in October 2018 as I mostly use original Kobo H2O.

I deregistered both and re-registered with users swapped. Found that on my Amazon account the "newly registered" model still had "Special Offers". Probably illegal under GDPR. Also they charge £10 to remove this even though the subsidy was years ago. I think it would be illegal behaviour for phone operators in EU who now must unlock a phone for free after a certain time to recover subsidy.

Battery life still not perfect not dreadful, more like what would be expected with an older built model.

So did more recent Firmware add a "secret wake & fetch adverts via WiFi mode" or was it the advert display blocking that made battery life so poor that not even one evening was supported?
Or could it have been a particular book? Books removed and easily swapped via Calibre as user always downloads from Amazon via USB and makes backups, thus reloaded.
I presume the actual downloads or any direct to Kindle KFX would be specific to serial number and thus not transfer to "new" reader without fresh download or DRM removal via Calibre plug in due to different serial numbers.

Copyright good. DRM is evil. I've deleted all the other person's titles from the exchanged Kindle.
