Can using a USB connection in car damage my iPhone's battery?

I want to connect my phone to my car for using maps etc. I have a brand new iPhone 16 and really want to get longevity out of the battery and have so far only used the provided cable for charging and correct plug. With my previous iPhones the battery life became poor quite quickly so really looking to delay this as much as possible. Will plugging into my car affect the battery over time. It’s a usb connection so would have to get a different lead. Thanks

No, plugging your iPhone into your car, I'm guessing to use Apple CarPlay will not degrade the health of your battery.

If you want to get best life out of your battery, read this link from Apple --> Batteries - Maximizing Performance - Apple

Plug your phone in to charge when you go to bed with Optimized Battery Charging turned on and leave it plugged all night EVERY night.

Never let the battery go to 0% and avoid letting it go below 20%.

More importantly, just enjoy your phone and understand that with every full cycle charge, the health of the battery diminishes little by little. This is normal. When the day comes that your Battery Health dips to 80%, just pay Apple to put a new battery in your phone.
