First work week with the Air. The Air was on cellular 1-2 bars around 10-12 hours each day. The battery life appears to be similar to my 2yo 6.1" iPhone 15 Pro. I set cellular data to LTE-only 9/25 onwards (for better upload speed indoors) and that change seems to have improved battery life as well.

I'm a very light phone user. Most of the drain is from background tasks and bluetooth devices.

If you own a Tesla and have terrible iPhone battery life, make sure that the phone key isn’t draining your phone battery

This doesn’t show up under the Tesla app usage stats, but it absolutely eats up battery.

Look for an entry with a car key icon next to your Tesla’s name showing as “connected” under Settings > Bluetooth.

The only work around I found is to swipe up and fully quit the Tesla app and make sure it’s not running when I’m home.

FWIW I have a Tesla and the phone key isn’t draining my battery.

To be clear, I’m not saying it isn’t draining yours or others’, but just that it isn’t draining mine.

@profets - if you’re willing to try deleting your phone key and Tesla app for a day and see if it makes a difference then it might be worth trying before going through the hassle of exchanging the phone.

Good thoughts - sorry missed these posts when I was reading through last night.

I noticed Tesla app in my battery use, even though I think it was showing ~2%?

I can definitely disable the phone key in the app and try for a few days without it, happy to test it out like that. Side note here as well - I don't recall exactly when, but newer Teslas and recent iPhones I think use UWB for more precision with location accuracy. I noticed with a more recent Tesla I have that it flashes and unlocks as I approach within a few feet and same as I walk away. Not sure if or how it might affect battery life in general anyway.
