I got my iPhone 15 Pro Max 2 weeks ago and its running iOS 17.0.3. Before I sleep I left it with 100% battery charge, waking up after 7hrs my battery went to 89% without even using it. Even though I followed all the settings in the internet on how to keep my battery from draining too fast but the problem still the same. I even put it on low power mode all the time. I hope they will fix this as soon as possible.

There is nothing to fix. Any cell phone uses energy continuously, as long as it isn’t powered off. This means that if it is not connected to power for 8 hours the battery level will be lower at the end of that time. How much lower depends on what apps you have, how many notifications you have enabled (which will be delivered and processed by apps even if you force close apps-they will relaunch when a notification arrives), and, probably most important, how strong your cellular signal from the network is; your phone maintains a "conversation" with the network so your phone can be found when a call or text arrives, and low signal strength requires much more energy to do this update to the network. Thus, you should be charging your phone overnight so this nighttime usage is powered by the external source rather than the battery.
And 11% overnight is a reasonable discharge rate for the normal things that any smartphone does; a smartphone is never without use; there are always processes running on it.

FIXED (for me): Hi Everyone from Italy! i had a costant battery drain in may new iphone 15 pro max from the first day of use. Always had iphones and never experinced something like that.
I tried in this order (after all the classic usual useless advice):
It slightly got better but nothing big.
Voillà the phone is now WORKING LIKE IT SHOULD!!! no more incomprehensible battery drain!
I had an iphone 13 pro max before so i know how it should behave.
MY ADVISE from my experience: DELETE and RE-INSTALL all the app you have in the iphone, from the haviest to the small ones and check the result!
I hope this can help someone <3, i was about to go crazy!
Best regards
The fact that most iPhones work, and don’t have this problem, means the problem is with your phone, not with software installed on millions of phones. So to solve it you need to either troubleshoot it yourself or contact Apple Support.
Note that both of the above have options to receive a callback or chat
Something is clearly running in the background on your phone even when you’re not using it. Look at the battery usage and see what the high usage item(s) are. Look at how much of that usage is background. If you don’t absolutely need it to use background use turn it off. Maybe delete the app(s) in question and re-install to see if that helps. Otherwise…maybe let your phone charge overnight so it will still be 100%. It won’t overcharge if that’s a reason why you aren’t letting to charge overnight. But your settings and apps work all of the time. Notifications come through…that’s using battery. Emails coming throughout the night? Same. You don’t have to be physically using your phone for it to still be using battery life.
1. Check Battery Usage:
- Go to Settings > Battery to view the apps and processes consuming the most battery. This can help identify any specific app or service causing the drain.
2. Background App Refresh:
- Disable unnecessary background app refresh for apps that don't require real-time updates. Go to Settings > General > Background App Refresh.
3. Update iOS:
- Ensure that your iPhone is running the latest version of iOS. Apple often releases updates that address bugs and improve battery efficiency. Go to Settings > General > Software Update.
4. Reset Settings:
- Resetting settings can resolve issues related to misconfigured settings without affecting your data. Go to Settings > General > Reset > Reset All Settings.
5. Optimize Battery Charging:
- Enable "Optimized Battery Charging" in Settings > Battery > Battery Health. This feature helps slow down battery aging by reducing the time your iPhone spends fully charged.
6. Disable Location Services:
- Turn off location services for apps that don't require them. Go to Settings > Privacy > Location Services.
7. Check for Rogue Apps:
- Delete or update apps that are known to cause battery drain. Check the App Store for updates or consider reinstalling problematic apps.
8. Turn Off Unnecessary Features:
- Disable features like AirDrop, Wi-Fi, and Bluetooth when not in use. Adjust display settings and reduce screen brightness.
9. Check Battery Health:
- Go to Settings > Battery > Battery Health to check the overall health of your battery. If the Maximum Capacity is significantly reduced, you may need to consider a battery replacement.
10. Contact Apple Support:
- If the issue persists after trying the above steps, it's advisable to contact Apple Support. They can provide more specific guidance based on diagnostics and may offer further troubleshooting steps or recommend service options.
To Lawrence Finch (level10?! Support)
Your response is extraordinary unhelpful - and borderline insulting.
stating “… millions of phones work… why don’t you fix it yourself…”
many of us reporting, including evidence(!) that this problem started with the recent os update.
example: my battery usage shows Apple Maps using 30% (2h!) usage since charge to full: and the app is not even active! Nor in the background.
users report deleting Apple Maps and using Google and battery drain went away.
please stop waving the problem away with a yedi-mind trick handwave.
im very disappointed.
It is not limited to the iPhone 15. My iPhone 14 Pro does that same thing for a couple of weeks / month now. Not sure when it started. Even during the day in airplane mode the battery drain stays the same. Location service on/off -> doesn't matter. Always on display on/off -> doesn't matter. No apps running when I check under Battery, doesn't matter -> constant battery drain per hour. LTE/5G disabled -> doesn't matter. Wireless disabled -> doesn't matter.
My iPhone 14 used to drain about 7% - 10% battery per night. I am right now at 30% or more and again during the day nothing makes a difference.
I erased everything and went back to all default (no restore / no additional apps) and that seemed to fix things and my battery drain is normal again.
I could try to add a few apps per day and monitor but it's really strange - especially because the phone doesn't show any apps in use - nothing. I think this started with IOS 17.x but I don't recall a 100%.
You can make an appointment at any Apple Store for free to see if your phone is behaving improperly.

Further, Apple and most retailers offer a 14 day return policy on iPhone; if you've had it "not even two weeks" you may be able to return it for a full refund.

The “charger” is a circuit in the phone. It stops charging at 100%, so it is thus not possible to overcharge an iPhone (or any Apple product) by leaving it plugged in.

I just bought an iphone 15 pro and the battery kept draining fast. I remembered with my 11 and 13 pro I had the same problem until I turned off location services. Once I turned off location services on the 15 pro it fixed this problem as well.
Hope this helps anyone out there who have noticed their batterys draining so fast.

For the first 24-48 hours after installing an upgrade, battery use will be higher because the phone needs to rebuild all of its internal databases.
Further, check the Battery statistics; there may be apps on your phone that are not compatible with the new iOS and require updates.

No there is definitely something wrong with the new iPhone 15 batteries. I am experiencing the same thing and my iPhone 13 did not drain this quickly. I am surprised there is nothing out there addressing this issue and just articles stating it could be “apps running in the background”. That’s not a good enough answer.
No, there is definitely nothing wrong with the new iPhone 15 batteries. However, there may be something wrong with YOUR iPhone 15, so make a genius bar appointment to have it checked out. How you can generalize from one phone to 100 million iPhones is truly remarkable.

Whether you are actively using the phone or not, it is continuously in contact with your local cell tower to let it know that it is there and available to take calls and receive text messages.
This can consume a fair amount of power, especially if you have a 5G connection to the cell tower and have two bars or less of cellular signal strength.
Same apple ID on two separate phones: 15 Pro and 14 standard, same configuration (except the specific stuff that exists only on the Pro models and dont exist on the standard), same 5G network (same SIM moved between phones, for testing purpose), same room, same night stand, the conclusion is:
The ugly part is that the 15 Pro also used the battery just at the same pace as the 14, but only for a limited time period of 2 weeks back in October. After that, it went back to heavy use.
And I do not agree with the overnight charging concept, because this issue is not limited to what happens during the night. It's the same drain while keeping the phone in the pocket during the day. If you do not carry a charger or a powerbank, you end up with low battery in the evening, maybe when you need it. Imagine a 1 day trip in the country-side. You want to be able to count on the phone to not drain while in the pocket. I was once in this situation, got lost in a natural park in Croatia, evening was near, got my 14 out and oriented fast.
It's likely an app on your iPhone 15; what does Settings -> Battery say is using most of the power?
You can always use Low Power Mode if it's an issue; my iPhone 15 Pro Max certainly does not do that.
Use Low Power Mode to save battery life on your iPhone or iPad - Apple Support
Your iPhone (or any cell phone, dumb or smart) is always actively on. Even when the screen is off. Any cell phone uses energy continuously, as long as it isn’t powered off. This means that if it is not connected to power for a period of hours the battery level will be lower at the end of that time. How much lower depends on what apps you have, how many notifications you have enabled (which will be delivered and processed by apps even if you force close apps-they will relaunch when a notification arrives), and, probably most important, how strong your cellular signal from the network is; your phone maintains a "conversation" with the network so your phone can be found when a call or text arrives, and low signal strength requires much more energy to do this update to the network. One way to deal with it at night is to charge your phone overnight so this nighttime usage is powered by the external source rather than the battery.
