I guess a good thing about carplay is that when traveling with someone else, they can use their phone to update things like maps, and we're not completely locked out of it until we come to a stop.
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.
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.
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.
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.
I can't recall for certain if my old S7 had that option but I don't think it did.
Most Androids today have that charge limit function natively without the need to root or tinker with your phone.
But then when I get in my car it will just stay charged at 100% all the time.
I think that fast charging is just as bad, if not worse.
And since the device it initially chooses to connect to sometimes takes 30 seconds or so to be fully connected (during which time you can't make any selections in this menu), you have to sit and wait until it connects the device you don't want to be connected before you can switch to the one you do want. And then you wait about 30 seconds for the correct device to connect.
Maybe not needed for newer cars?
I start the car and wait for the dashcam to chime. I start driving once it chimes. I have an older Aukey, not hard wired, so it takes about half a minute for it to chime which I thought was perfect timing.
You can’t quite do that with any car I’ve been in. CarPlay is close; it would be great if that became an open standard with standard connectors.
It's inconceivable how the pairings are so bad and there isn't just a button for each phone connected that just works. Even when switching does work, all it takes is one blip and it hops over the other phone.
Again, this is on multiple cars on long road trips where we have at least two people to work on it and literally hours to figure it out. We generally settle on a single phone per car now, because it just isn't worth it.
