Apple Car play charging

[usn90]

I use my iPhone for Waze/maps for work, plug it in with the usb so that I get the use of the screen in the car.

The issue I’m finding is I do hours of driving per day, and there doesn’t appear to be a way to have the phone connected to the stereo via the cable and NOT have the phone charging at the same time, I think I may be doing the battery health no good.


Is there an option here I’m missing in settings so I can use car play and not charge the phone at the same time?

It can't be disabled - carplay is quite resource intensive so would discharge quickly if not charging.

Not that I've seen. You could use one of the wireless carplay adaptors (Carlinkit, cplay2air, etc) plugged in to the USB and not have to plug your phone in at all.

Thanks for the replies.

Will have a look at those wireless adapters.

What would be worse for the battery though, having the phone on constant charge whilst it simultaneously drains from car play, or using the wireless adapters, draining the battery and then having to charge it to full again?

What car is it. Mine doesn’t need to be plugged in as car has a wifi link built in.

He’s looking at an adapter to do the same

battery life should be fine, my iphone runs waze for 3+ hours a day whilst on charge the whole time

when i sold the last one (2 years old), 500 days of high use on charge, the battery was at 96% capacity

most damage occurs below 20% increasing below 10% and getting real bad by 0%

Leave it plugged in. Li-on batteries don't like being drained and re-charged. Save the money on the wireless adapter (and the time sorting it out when it doesn't want to play nice) and replace the battery in a couple of years.

I’ve just replaced my iPhone 8 with a completely knackered battery with a new 14 Pro. Wasn’t sure if I’d been making things worse by having my phone constantly plugged in whenever I was in the van to use CarPlay, even if it was relatively short journeys.

There is an ‘Optimised Battery Charging’ option in the settings, with that enabled hopefully the phone will be clever enough to work out the most efficient way to charge itself.
