    With the announcement of CarPlay updates for iOS 12, I’m interested in buying a new receiver for my car so I can get rid of The bulky phone mount I have.

    Im a big fan of Waze, so having it “built into” the dash is appealing.

    But: Waze also eats lots of battery.... so anytime I’m using it, I keep it plugged in.

    Does CarPlay Wireless improve battery usage (maybe by not needing my screen on?) or worsen it (now it’s sending data to an external screen while also using the radios in the phone)?

    (I like the idea of wireless car play, but if I need to keep my phone on a charger the whole time, I’ll just save money with an older unit that plugs into my phone...)

    I don't have wireless CarPlay, but I have some thoughts.

    You are asking how the battery life would compare between an iPhone on a mount using waze, vs wireless CarPlay?

    So, I guess the question would be does Bluetooth and wifi, which is needed for CarPlay, use more energy than having Waze right on the iPhone screen? I would say that using the Bluetooth and wifi would use more energy than lighting the screen.

    Even if it didn't, and you actually saved some energy from using the CarPlay screen, like you said, Waze is a battery hog, so I doubt any energy savings that happens wouldn't matter much.

    It is probably the GPS that is causing Waze to eat your battery, not having it on the screen.

    Wireless CarPlay consumes battery noticeably faster than just normal phone usage.

    (Have been using Alpine ilx-107 for 2 weeks. Love it. I connect nothing and it works perfectly.)

    Now, I need to figure out a magnetic wireless Qi car charger to complete the theme for longer car trips. They are very reasonably priced on Amazon.

    The idea of a wireless solution appeals to me, but not at the cost of battery life. True I can get wireless chargers and I have a few at home, but unless you find one that is magnetized (with a corresponding case), think the phone would shift while driving and wind up not charging. I have too many Qi chargers where the phone has be in the right position to keep charging.

    I just put in a Sony head unit in my wife’s car and just bought an Alpine F309 for my truck. CarPlay is pretty cool, but maps feels limited coming from my OEM nav. I’m really looking forward to having Google Maps instead.

    If you find a wireless charger that works well in a car, let me know!
