You should be charging your phone overnight. That way the inevitable overnight usage will come from the wall outlet rather than the battery, thus extending the battery’s life before it needs to be replaced. And it has the added benefit of allowing you to enable automatic overnight backup, so you won’t lose a significant amount of data in the event of disaster.

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.

iPhone 15 Pro Max battery draining without use

I got my iPhone 15 Pro Max 3 weeks ago and its running iOS 17.0.3. Before I sleep I left it with 35% battery , waking up after 7hrs my battery went to 0% switch off without even using it. I spend money $2200 😂😂😂

I am having the same problem I think it started with that update we had in December, new phones shouldn’t be losing battery life this fast my iPhone 13 lasted all day and then some!!! Fix the issue please apple

My iPhone 15 pro max has been behaving similar people affected by “Covid-19” when it comes to performance. Its security features are proven to be a complete failure. They hope that the Developers are reading these feedback. The behaviors of this phone has been due to the continuous attacks and malware. I have already processed a full factory reset on this phone more than 10 times by using my Mac. However, after just a few days the issues will penetrate into the device again causing all sorts of problems. As of current, and this started yesterday, I am seeing that an item lists as “Recently Deleted Apps” have been using up a significant amount of battery like 17-22%. It’s the second item under the battery statistics. How can deleted apps remain hidden and running on battery? Totally nonsense.

I'm having the same issue with my Iphone 15 model, battery is almost draining 10% everynight, even I charge my phone to 80% and put it on charge at 20-25, background refresh is off (only WIFI), location services completely off, yet the same thing is happening. This is my first apple device and I'm so disappointed with the battery drain in idle mode. Even my 5 years old MI note 7 pro has less battery drain in idle mode around 2-5% only.

My iPhone 15 pro max is 3 days old and I feel like my battery is dropping like crazy! the total active screen time from the first use of the device doesn’t even make 4 hours! Furthermore, I’ve even been using it on low power mode ever since. Updated the iOS and also the settings, I believe all the settings are set in the most battery friendly mode. My charging technique is ideal as well, no heating issues, no use of any kind of performance demanding apps and likewise stuff. Somebody up with a resolution?

I have been experiencing all sort of security and hardware issues with my iPhone 15 Pro Max as well:

1. Couldn’t get the “Advanced Data Protection” to enable even after trying it through a screen sharing session with several Apple Sr. Advisors. Then I was scheduled for in-person appointment at a local Apple Store to go over the process. The night before the appointment, I decided to trying it out again, the feature ironically worked.
2. Now, soon after, downloading any new Apps from the App Store is taking anywhere from 10-20 minutes. Often when navigating through the websites have been impossible.
3. The device battery is draining over night without any valid usages except that there are Apps as expected running a refresh on the background, most of which are, the default Apps. This is important for the Apps to remain updated.
4. As of the last two days, I noticed an item under the Battery usages showing up, and this is called “No cell coverage”. This is a very suspicious item which could be anything, and it is the item that’s currently using up the highest battery %.
5. Discussions about this issue with several Apple Advisors today have led to no where. All, very concerning. Apple set up such a high price tag for the iPhone 15 Pro Max device but there are more issues with this device OS than every other devices from Apple. I recently even purchased an older version of an Apple iPhone, 13, and to test it out for myself and had no problems. I obviously returned it back to the store because it was just for testing.

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):

• network reset
• settings reset
• soft reset of the phone

It slightly got better but nothing big.

• Theeeen i canceled tiktok-instagram-facebook and installed them again after an hour:

Voillà the phone is now WORKING LIKE IT SHOULD!!! no more incomprehensible battery drain!

• (in addiction i also cancelled some small apps and update all, but i don't think those were the problem)

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

If you follow best practices and ALWAYS charge overnight you will wake up at 100% every day.

Of course, if you lose the phone now you will not be able to find it using Find My.

I’m using iPhone 15, the battery is draining so quickly, whether I’m using phone or not, it’s just not performing well. Very disappointed by the battery of 15 series.

Correct. I am slowing adding my most often used apps back (a few per day) to my iPhone and monitor any change in battery consumption.

Last update for me, since my problem is solved now.

iPhone 14 Pro: charged on Wednesday 1/17/2024 10:06 am to 82%

Today, Friday 1/19/2024 at 10:09 am the Battery is at 50%

That is 32% power consumption for 2 days. I am a lightweight iPhone user: a few Whatsapp, Authenticator for work, a few phone calls etc - so your mileage may vary but it was crazy before with this usage pattern to only have 15 hours of Battery with my iPhone.

I got iPhone 15 last 2 week ago and i face the same issue when i was sleeping my battery 50% and when I woke up my mobile battery was 35% I hope you guys fix this issue soon
