Battery Drain on iPhone - Apple Maps - iOS 16.x

Just quit Maps when not actively using it.

You also don’t need to delete Maps; simply going to the app switcher and swiping up on it should be sufficient.

It doesn't matter. I have mine connected via USB and the phone gets hot and stops charging. This happened with a authentic Apple cord and both of my vehicles and only started happening after iOS 16 update. If I don't force close Maps after unplugging my phone from my CarPlay radio, it will drain the battery from near full charge to 20% in less than 1 hr and the phone is super hot. Again, this issue never happened before the iOS16.x update. iPhone 12Pro. Its really frustrating. Not sure why it does this.

I am also having this issue. I've taken it to the Apple Store twice now and they were saying it was likely the charger that I was using although it was an authentic Apple MagSafe and also Lightening Cable. The second time I went they stated it could be the case I was using or that I have to update to the newest iOS software. I have the latest iOS and this still appears to be an issue.

If you leave the Maps application running it completely eats your battery. This morning I used Maps to get to work and of course, I was in a rush and didn't close the application when exiting my car. I was in meetings all morning and left the phone on my desk. When I returned my battery life had diminished from 95% to 27%, the phone was overheating as well. The battery gets very hot especially if I keep it in my pants pocket while driving.

I hope they find a fix and the answer isn't just "Delete Maps."

Were it an iOS glitch we'd see tens of thousands of similar reports, and we do not.

It may be a combination of cellular conditions in your area or within your vehicle and the charge capacity within your vehicle.

Many people are using CarPlay/Apple Maps all day every day and do not experience this issue.

You may also wish to check with VW and see whether they have any applicable firmware updates for their head end.

what I don’t understand is why I never had this issue pre iOS 16. Post iOS 16.x it does this, never use to. And plugging in the phone doesn’t help as the phone will give me a message that phone not charging, will continue when cool enough. This is in either of my vehicles, new cable, authentic apple cable, old cable… one is a factory radio, on is an aftermarket Sony. Doesn’t matter, and that is with my old iPhone 12 Pro or the iPhone 14 Pro. So considering I’ve tried literally removing all variables, it’s seems like it’s an iOS issue.

now, that said, I did have another theory, is TikTok maybe using a back door through iMaps that is causing the issue, guess I wouldn’t put it past them.

I challenge you to find where I said people's concerns were baseless; I stated if your phone is overheating you will see the message.

The vast majority of owners are not seeing this issue, and yes, tens of millions of iPhone owners use Maps daily, so the question becomes why those that are seeing issues are.

I recommend those experiencing this issue have their phones examined:

Genius Bar Reservation and Apple Support Options - Apple

or contact Apple Support directly:

as no one here can solve this or direct Apple staff that can.

I’ve had my responses to you deleted multiple times, and not sure why, as I haven’t said anything mean or derogatory… but what ever.

I’ve stated mine gives the heat warning, my phone gets extremely hot. What irritates me the most is that just because others don’t have the issue, it must be a user error, yet I never had this issue with iOS 15. It instantly showed up with iOS 16.xx update. I’m on my third different model iPhone since then, and the problem persists.

and apple can’t find the issue… or just don’t care.

Same issue. ios 16.4.1 on 13 pro.

Phone ran incredibly warm and battery drained while wirelessly connected to carplay in my bmw IX. Deleted apple maps completely, and problem seems to have gone away.

I never have battery drain from a mapping app because to me there is zero reason to leave it running if you’re not actively navigating with it, whether it’s Google Maps, Maps or Waze.

Then contact Apple Support directly as no one here can address the issue:

I agree. Once I deleted Maps, the issue went away. No more hot phone, no more charging issues and my battery lasts a really long time.

Hi mat141,

Thank you for posting in Apple Support Communities!

For assistance with your Battery and Apple Maps, you'll want to reach out to Apple directly.

Take Care!

Update. I was asked to remove the Apple Maps from my phone for a few days and use another nav app for a few days. No issues with Waze or google maps no issues. I’ve reinstalled it and the issue came back. They are following up tomorrow. Sounds like I will need to go into the Apple Store.

side note. I’ve found that it you close out maps it at least stops the drain/pauses it.

It has to be a major glitch. I’ve been into the Leicester Apple Store and they ran tests and pronounced that all was fine on my iPhone 12. It isn’t.

Since updating to v16.x and now, worse, changing to a VW ID.3 car, the battery drain and heat from using Apple Maps - even with the app off, and with background app refresh off too, it continues to run in the background and is far too pronounced to put up with.

I trust Apple will get the glitch resolved in v16.5.
