iPhone 16 Pro Battery Draining Quickly

Jeff Donald is spot on. Those apps have been pointed out as consuming too much battery in this post as well as many others and users that have removed them found their battery returning to all day use. It will take an update from those developers to resolve that problem, but until that is done you can expect the same outcome. Apple gives you the option to view the apps that are using up your battery so you can make that decision on whether you want those apps using up your battery or not. Developers have the incentive to use the limited battery resources responsibly as they don't want users to remove them.

That could certainly be one of them, but more likely Instagram, WhatsApp or those that note the Background Processes when viewing the battery usage. Post the screenshot of your last 24 hours by apps to identify as others have done. It is not a coincidence that the same apps appear on everyones screen shots.

Let us know the results of removing WhatsApp. We just have what other users have posted to go by. It clearly does not affect all users with the iPhone 16, so finding the common denominator will be essential. The WhatsApp draining issue has affected previous iOS versions and other devices as well.

Hi so Apple support called me one alarming issue if you look at the attached photo is my photo usage: I was on photo screen time 3 hours but background was 11 hours. They said the “big new update” may fix the battery drain issue but I didn’t want to loose my 14- day return window. I returned my iPhone 16pro Oct 26 and upgraded to IPhone 16 pro max.

In regard to your battery issue have you had you had your iPhone diagnosed by Apple Support either over the phone or in person at an Apple Retail Store? If the issue persists, it can be escalated to engineering if necessary.

sir My brother also have iPhone 16 pro and his battery backup is very good even he is also using Instagram , Snapchat, YouTube, removing all these app is not aa solution, 4 to 5hours backup. Seriously it seems to joke iPhone 15 pro even batter than iPhone 16 pro in battery backup . Please resolve this problem

That is your choice if you are unwilling to remove them to isolate the problem to those apps. Only the developers of those apps can resolve the problem, Apple cannot. The Social Graph that the apps use for each individual is very different and the data points used will not be the same. What prompts the app to wake up in the background on your brother's phone to process new data will be very different than yours. Your issue will continue as long as the developer has not resolved the problem or you continue to use the app. It makes no difference what device you are using.

It is basic Troubleshooting 101 to identify the problem. You could even switch phones with your brother is realize it is not your device that is the problem. It is your data that those apps are interested in collecting and it takes battery power to do that. You have many more data points the apps are interested in than your brother, it is that simple.

SOLUTION:

Head to your iPhone settings, go to General< Background App Refresh and turn that off. it won't affect your iPhone's use it will just have apps not refresh their content while on Wi-Fi. That should help.

Another thing you can try is to make sure you have an Apple USB-C Charger Cable and Block.

Does anyone know how to fix this problem? I am having a hard time especially when I’m outside and no access to charging. I have this phone for more than a week already. I thought it’s only calibration issue but I think the battery of 16Pro is just poor considering the amount you have to pay for this phone.

It is unclear if you have read the posts here and identified the same apps as others that have yet to be optimized by the developer. For the most part it has been a Meta issue. Feel free to post your battery usage as other have showing the last 24 hours.

Comparing between models is mostly irrelevant. Why? They utilize different hardware, different firmware and different software. You’re making assumptions that two different models need to deliver identical usage and it’s not the case.

WhatsApp is making greater usage of the high performance processors and depleting the battery much faster. Why would that be? They aren’t spending the time to optimize the code to run efficiently on low power processors. Why should they? Have you complained to Meta about the performance of their app? If not WhatsApp, what app is consuming your battery capacity on a daily basis?

Same here!!!

Meta Facebook Messenger app seems to be quite active.

Remove that app, and test again.

If the problems resolve, check for iOS and app updates, and then check with Meta Facebook Messenger support.

I went to my background app refresh setting and basically turned off all the background app refreshing except 2-3 that seemed to help! I don’t know how I had it set for my prior phone.

Your apps tell the story. Why is instagram using 41% of your battery capacity in just a few hours? Why?

An optimized app can go much longer, lets look at Safari.

Lucky you! With my 16 Pro what I did was to:

1. I went through the initial setup on the day I purchased the phone
2. Then I connected it to my Mac and performed factory reset (DFU > Restore iPhone)
3. Used iCloud to login but did not restore the phone from the backup (only iCloud contacts, photos) - I installed apps manually.

Unfortunately, in my case the battery life remains pretty the same. I did the same with 16 Pro Max (returned to the seller), 16 Pro 128 (1st unit - returned to the seller) and with 16 Pro 256 (2nd unit which I don't plan to return). All units were not so effective when it comes to the battery. My average SoT in 16 Pro after 6 days since the first setup is 4-6h + some time when the screen is not active but the phone is working.

I can't believe that this is a unit fault (16 Pro Max and 16 Pro 128 were from September, both unit and battery. My current unit 16 Pro 256 was manufactured in October, both unit and battery). So it ether iOS fault or these phones simply can offer only this battery life in case of my usage pattern.

Here are the steps provided by Apple to reset your iPhone using a computer. Should be fine restoring from a backup as you are really just interested in getting the OS installed again. Definitely make sure you have a backup, as the phone will be wiped clean. No doubt some apps are notorious for battery drain, such as Meta apps, but restoring the OS may help as it did with TAS22.

Restore your iPhone, iPad, or iPod to factory settings using a computer - Apple Support

Following the tips from here 11 Proven Steps to fix iPhone 16 Pro Max Battery Drain Issue I went through the apps individually for access to Siri, I untoggled it for each app as I don't use Siri and made some of the other changes as suggested. After all of this Did a hard reset ( force restart ) of the phone and battery life is much better now
