iPhone 16 Pro Battery Draining Quickly

Iphone 16 pro battery seems so poor. I unplugged my phone at 9:15 am and by 4pm it had only 32% with 3hrs of screen time. I did my 0.5gb update hoping it will extend baterry life and upgrade functionality of my iPhone.

How is it possible? Anyone experiencing bad battery life as well?

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

Apple makes it very clear where the problem is in that graph. With less the 4 hours of Screen Time using the apps, you can see exactly what has consumed your battery not only while using the app, but in the background when it is closed. I don't know how that can be more clear.


You spent $1200 on a phone to install apps that collect your personal information to sell to advertisers and are making far more than that by using you as their product. That is the choice you made. If you don't like it, contact the developer of those apps and see if they care.

I purchased a new iPhone 16 and had the same issue. I discovered the background app refresh defaulted back to all apps again.


Background App Refresh on an iPhone allows apps to update and check for new content in the background, even when you're not using them. To turn on (or off) Background App Refresh, you can: 

  1. Open Settings 
  2. Select General 
  3. Tap Background App Refresh


I only have a few apps I would like to refresh in the background so I turned the other 100 or so off. Battery life increased dramatically.

I bought 16 pro max almost 10 days ago and it was working fine but from today mu battery facing drain issue without heavy use. I lost 35% of battery in less than 3 hours without heavy usage. Too much irritating thing. Tell me the solution

After reading this post, what steps have you tried?

  • Reset using computer
  • Force Restart phone
  • Removed the known apps that have caused the problem and compared your results
  • Taken it to Apple for diagnostics


If you have tried those steps and you still find it irritating, I would suggest that you return the phone. In most regions you have 14 days, and you should not keep a device that you are having trouble with.

So did anybody find any solution for this or we just have to wait for Apple to fix it?
Because I have iPhone 16 Pro brand new two weeks old maybe 3 and my 6 years old iPhone 11 has almost like equal battery life to the 16 pro that’s crazy.

There are some in this thread that have fixed it and other similar threads as well. Here is the post provided by neutro_phill:

Update 2: My battery life has improved significantly on the 3rd day. Only charging it overnight (with nightstand on). It’s 11 am here and my battery level is 93%. Ending my participation here in the thread and all the best to you all. Keep it charging all night.


Not sure if you have tried any of the other solutions provided, but these are the most common:

  • Remove Facebook and WhatsApp, then compare your results. These apps from Meta have been running background processes consuming your battery even when not using the apps.
  • Reset iPhone using a computer

You have the exact apps that have been the cause of the battery draining that has been reported here and it will continue until those developers update their apps or the user quit using them to force a change. The Screen Time only reflects when you are using the apps, but the apps are using you after they have been closed.

  • Instagram
  • SnapChat
  • WhatsApp


The background processes those apps run continue even when you are not using those apps and they are free to use because they are gathering a tremendous amount of data from your activities to build a Social Graph to target specific ads to you. The data it is collecting could be listed here, but frankly it would span a whole page for those 3 apps. You can view the information yourself by viewing the Privacy Page for each app in the App Store. How do you think they make billions in revenue when you are not paying them anything to use the service. You are the product.


The test is simple, remove them and you will have all day battery life. Apple gives you that page to identify the energy hogs, so now it is up to you what you do with that information. If using the apps is more important to you than the reduction of battery life, then that is a choice you make. The solution for bugs or performance issues with apps is to contact the developer or don't use the app.

Sir, my iPhone battery is draining 1 % in 4 minutes of usage even sometime 3 mintutes without using intragram just simple browsing and battery decreases in every 3 - 4 minutes 1 % this is problem with iPhone not with intagram and so all if I am not using that iPhones battery is decreasing 1% in 3-4 mitnutes

It makes no difference if you are using Instagram or not. The app is consuming the battery in the background just from the activities you are doing on the phone. You can continue to complain about it, but you have been given all the information and simply refuse to remove those apps to test your battery usage then. Instagram is just one of the apps and your problem is compounded with the addition of the others. Take for example the information Instagram is gathering on you whether you are currently using the app or not. This is available on the Privacy Page for Instagram in the App Store.
