ChatGPT tells me thats very likely Puya PY32F002A and that can be as cheap as $0.0682 a piece if you order 5000 and upwards, which should be fairly the case for a mass market vape.
Hearing the term microcontroller makes you feel like a lot of compute capacity is being wasted. This is what you get in that microcontroller-
Puya PY32F002A: Cortex-M0+, up to 24 MHz, up to 20 KB Flash, 3 KB SRAM, ADC, timers, I²C/SPI/USART; available in QFN20/TSSOP20.
Its basically a small battery, a display and a microcontroller to show you battery charge and vape fluid levels. Mostly ADC work and display.
How long does this thing typically last? iPhone is disposable for some people and it surely has some amount of tech inside.
Not a smoker (never was), but it seems like these are emptied within a few days on average. I would consider that overly wasteful.
Some countries have already enacted bans on dosposables. A EU wide ban might come soon.

I stumbled upon this video a few days ago: https://www.youtube.com/watch?v=dy-wFixuRVU
so recycling the batteries of the vapes is apparently a thing
