The main problem with PHEV is, that's it's comparably small battery will age very poorly because it will both: a) do more charge/discharge cycles per distance driven, and b) get charged and discharged closer to 0 & 100% making the battery age even faster.

I'm not sure where you're getting this idea from, but my PHEV (BYD Shark 6) doesn't drop below 22% battery as the engine is there to charge the battery, not propel the vehicle.

I also believe that most pure BEV drivers would charge their cars daily to mitigate the risk of range anxiety.

(not parent poster) I got the perspective from people that wanted to help other people, but stopped repairing PHEVs:

The difference with BEV charging is that the battery is much bigger and it's a core component (it's properly serviceable), so I can charge it at 60%, keep degradation at bare minimum, and still have 270km of range. With a PHEV you'll need to always charge it 100% to fully use that EV range, so the battery will degrade way faster due to way more cycling.
