I really liked wireless CarPlay when testing the Enyaq and wondered about the multi user situation. Already today Bluetooth always seems to get exactly the wrong phone. In our current setup we just have a phone holder with plug in which we shove the phone. Then it is done. It takes longer to pull the phone out of the pocket than to connect it.
The only downside to CarPlay is that the battery stays at 100% charge. I wish I could limit that to 80%. Especially if we take long drives this degrades the battery unnecessarily.

I think that fast charging is just as bad, if not worse.
The batteries used in phones degrade quickest below 20% and above 80% of charge. This is already at room temperature. When the batteries or phone is hot the degradation at those state of charge (SoC) is even worse. In the car when using CarPlay the phone can get really warm, especially if it is in the sunlight which tends to happen easily. When left in the shade it gets hot due to restricted airflow.
Therefore I would like to limit the SoC on my phone to not excessively degrade the battery. I very rarely, if ever, need more than 80% of the design capacity of my iPhone anyway. So I prefer it to last longer.
100% isn't over-charging. It's just not the GP's preferred spot on the battery energy (hours of charge) vs battery lifetime (days/years) curve for daily use.
I do wish phones would provide more control here. I would also take 80% charge many (but not all) days in exchange for my battery life after a year staying higher.
lmgtfy: Its the extremes (0% and 100%) that degrades LiIon the quickest, if you want the longest life ideally you'd keep it 30-70% the whole time, ymmv (and also thresholds).
And it is a pity manufacturers don't support you in doing stop-charging-at-x if you wanted, e.g. a simple thing for software to do, but impossible without rooting on Android.
Its been a feature since at least the S9. Source: Had to 'fix' my girlfriend's phone only charging to 85%. Was a mystery how that setting got randomly enabled, really.
I can't recall for certain if my old S7 had that option but I don't think it did.
Although that's not really a downside of CarPlay itself, and you can also solve that with the Optimized Battery Charging feature, in iOS 13 or later. So just turn that on.
I have it turned on and it helps when charging during the night. It will charge until 80% and then charge until 100% for just in time when it thinks I need it.
But then when I get in my car it will just stay charged at 100% all the time.
