iPhone 15 Pro Max battery draining without use

If you search the forum you will see a steady stream of posts about perceived battery drain issues, not just for the latest iPhone, but for EVERY iPhone model ever sold, and after EVERY iOS update ever released. So clearly all iPhones have battery drain problems all the time. I’ve listed a few of them below.

Specifically, if your previous phone did not have 5G network capability then an iPhone with 5G will use more energy than an iPhone with LTE, 4G, 3G or older technologies, both because 5G inherently uses more energy than 4G for the same connection, and also because 5G network deployment is still being built out, so towers that support 5G may be further apart in your area, and thus phones need to post power to remain connection.

I started by saying that battery issues occur to a few phones with all versions after an iOS update, and the responses implied somehow that iOS 17.0.3 was “different” and was an issue that hadn’t happened before. So to back up my statement here are some threads on battery issues with previous versions (far from all of the relevant threads, but a reasonable sampling):

The bottom line is that it isn’t a problem with the specific version, and, if you want it resolved, you need to troubleshoot why your phone has this problem when 99+% of over 1 billion iPhones do not. 

Mine is an iPhone 15 pro, and I have the same issue 🙄 my brother has an iPhone 13 I took a screenshot of its battery before sleeping at night in the morning it only dropped two percent but mine dropped 13 percent.

I had an iPhone 12 Pro and it was fine with battery. I listen to podcasts at work and I would get out of work with 70-80% remaining. I now have an iPhone 15 pro and I get out of work and am at 20% and need to charge when I get home. It’s wild, the battery clearly has an issue. Not doing anything different that would use battery like that. According to my battery section in settings it says Spotify running in background used 11% battery life in 1hr 20mins of background use not screen on. So in my 10hr shift I’m lucky if I get out with 20% remaining. iPhone 12 Pro I’d walk out with 70% remaining easily

I’m using iphone 15 pro max for almost 2 months.In 17.2 I didn’t seen overnight battery drain even if my internet was on at night,but after updating to 17.3 my phone’s battery gets low fastly,and even when my internet,bluetooth,wifi and even location services were off my battery got dropped overnight.Apple this is not what to expect form 15 pro max.17.1 was the best in terms of battery,but now in 17.3 it’s really bad.

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.

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 experiencing the same thing! Went from iPhone 13 Pro Max to an iPhone 15 pro max & my battery life is either the same or worse! I think it’s a processor issue. Because I can be on this site or the regular Apple website & it might go down 1-2% in 20-30 minutes while in use. But right when I close the safari app out & turn the screen off & yet in approximately 30-120 seconds the battery will immediately drain another 1-2% after I tap the screen for the screen to come on. So basically it uses more battery when not in use than it does while being used. The always on screen, location services, Siri, automatic updates & downloads, Bluetooth, iCloud cellular synching, hotspots, airdrop, background refresh, keyboard haptics, rise to wake screen, etc. are all off.

Hi Everyone!

I've got the same problem in my new iphone 15 pro max.

It has a clear battery drainig problem. My iphone 13 pro max was immortal, when not in use it dropped max 1% in one night. The 15 pro max is always dropping percentage and it last worst then an 83%(battery capacity) iphone 13 pro max.

For sure it is a software problem, we need to find the cause that affect us. Probably it's just a bug on some settings that makes the software spend energy for no reason.

Thanks everyone!

You could easily be letting your phone sit too long at full battery while plugged in. Or you could have let your phone die completely way more times than she has. Both of those are extremely detrimental to battery health and capacity.

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

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.

something is ALWAYS running on every smartphone in the world, all 6 billion of them, even when you’re not using it, as I said in my previous post.

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.

Exactly! I don’t know why everyone is trying to justify that this is just what happens when running apps in the background etc…

No there is something wrong with the new iPhone 15 batteries. It’s a brand new battery and the point being made is the battery shouldn’t be draining nearly as fast as it is with being BRAND new.

At least someone gets it!

I recently migrated to IPhone 15 pro max from iPhone XS Max .

I too am experiencing that my iPhone 15 pro max is discharging much faster than iPhone XS Max with similar apps and usage. Phone is mainly on Wi-Fi at home / office or on 4G network , 5G network is ON only on very rare occasions ( may be 5mins in entire day) .

I still have my iPhone XS Max with me and it battery health is 80% but it gives me a better battery back up than the new iPhone 15 pro max with 100% battery health.
