The newest update has been decent, bringing a change to the system applications, improvising the lock screen, and assisting in managing the notifications. It may have gotten better, but if you’re wondering, why does my phone battery die so fast? Then you’re not in this alone!

After the update, many people have complained that their battery drains pretty quickly. Even though their usage is the same as previously, that’s not what this is about. iPhones have always been tricky, especially after an iOS update. So, if you’re wondering how to fix the iPhone battery drain issue, here’s a list of troubleshooting to assist you and your fellow iPhone users. 

Let’s find out!

Why is My Battery Draining Out? 7 Ways to Fix It!

Why is My Battery Draining Out? 7 Ways to Fix It!

Here are some reasons why your iPhone battery is draining out fast and how to fix it to avoid this issue. 

Close All The Live-Activity Applications on your iPhone

If you’re trying to navigate your way to a friend’s place using the Google Maps application, booking an Uber, and even checking the food delivery app to check when the food will be delivered. Then remember to swipe all of it up when you’re done to shut down any live activity apps. These apps drain your battery. And you keep wondering what you did for the battery to go down so fast. 

So, the minute you have used them, it’s advisable to swipe up and close them instantly. They keep using the power because, according to the app and the phone, you’re still not done with them, so they keep updating data. 

Turn Off the Keyboard Haptics

Is your iPhone battery dying fast? Another reason can be the Keyboard Haptics that have been drying most of your battery juices. Even though the iOS 16 has improvised the keyboard haptics, it delivers an outstanding user experience. You can quickly deactivate it by following the steps below:

  1. Tap on the Settings application on your iPhone.
  2. Then scroll below and tap on Sound and Haptics. 
  3. Scroll below to select the Keyboard Feedback option, and then turn the toggle for the Haptics to disable that from the provided menu. 
  4. And voila! You’re done.

Pause the Fitness Goals

iOS 16 brings yet another ease for its users; if you are considering investing in an Apple Watch, we advise you not to do it. After you have upgraded your iPhone to the latest iOS, a new application appears by the name of Fitness. This was previously only available on the Apple Watch. This application will help you track your activity, ask your goals, and help you meet them. It has sensors that help keep a check on the activity, such as the number of steps you have taken, the amount of calories you have burnt, etc. 

Even though this was done previously, too, this app elevates the experience, and while doing that, it does knock your battery down. If you haven’t set it up or do not require it, then you can choose to pause it or opt-out. Here’s how you can do it:

  1. Open the Settings app.
  2. Now tap on Privacy and Security to open Motion and Fitness. 
  3. Then, turn the toggle off to close the fitness tracking on your iPhone. 

Disabling the Always-On Display

One of the critical reasons why the iPhone battery drains very fast is the Always-on display. Although the feature isn’t entirely finished, it keeps the display pixels open. A lot of people have disabled it, which has resulted in a better battery life. Here’s how you can do it too:

  1. Tap on Settings on your iPhone and scroll to Display and Brightness. 
  2. Now tap on the Always-On Display and deactivate it by turning the toggle off. 
  3. And voila, here is another measure you have taken to save your battery!

Avoid Creating Different Lock Screens

With the option of customization of lock screens in iOS, many users might just go crazy. But don’t be one of them because it is also one of the reasons your iPhone battery drains fast. Instead of going overboard, whenever you want to change your lock screen, you can just take a minute or two to customize it and then delete the old one because there is a meager chance of returning to it. 

Here’s how you can get rid of the old lock screens so you are not left with a disappointing battery percentage:

  1. Press your iPhone’s power button, which helps you open the lock screen. 
  2. Now tap on your iPhone screen for a few seconds; do it until it opens the customization menu for you. 
  3. Swipe up on the previous lock screens, and then tap on the bin. This will then delete the extra lock screens. 
  4. And you’re done! 

Photos and Videos Duplicate Detections

The iPhone Photos app is another culprit and the reason why your iPhone battery is draining so fast. It automatically indexes your photos app to search for any duplicate videos and pictures depending on the number of media you have saved on your device. Since this process runs in the background, you might need to be made aware of it and wondering why my battery is draining so fast. 

Unfortunately, this is an issue you cannot weasel your way through. However, Apple says your iPhone needs to be closed and connected to charging to avoid it. You can do this overnight as it fastens the detection process and prevents your iPhone from draining. 

Live Lockscreens Aren’t Your Best Friend

As beautiful as the live lock screens look, they are a sworn enemy of your iPhone’s battery. With the update, iOS 16 brings a chance to choose from a series of new wallpapers such as emoji ones, weather, solar systems, and more. It’s advised to pick a standard wallpaper to ensure your battery juices do not run out quickly. Here’s how you can do it:

  1. Open the Settings application on your iPhone and scroll to the Wallpaper menu. 
  2. Now, tap Customize to open the home screen or lock the screen customization menu. 
  3. Choose any picture that you can download from different apps such as Pinterest to ensure you keep your aesthetic. 
  4. And then Apply it here!


  1. How do I stop my iOS 16 battery from draining?

Another quick way to stop your iOS 16 battery from draining is by enabling the low power mode. You can do it by following the steps below:

  1. Open the Settings app and search for Battery. 
  2. Now enable the low power mode by clicking on the toggle. 

This ensures your battery juices are used less, and hence, it dies down slowly. 

  1. Will Apple fix the iOS 16.6 battery drain?

Apple won’t be able to fix it, but since it is an issue faced by many people, they might work on improvising it in the next update. Until then, you can just take a few measures to ensure your battery doesn’t drain quickly.

  1. Do iOS  16 widgets drain the battery?

It’s essential to use the least amount of widgets on your iPhone’s lock screens. The applications of each widget are running in the background, meaning your battery drains pretty quickly. Remove unnecessary widgets, and if you want to check your emails or the weather, it’s better just to open the app check and then close it again by swiping up. 

Bottom Line

‘Why is my iPhone battery dying so fast all of a sudden?’ you now have an answer to this question! There are a few tricks that you can follow to get your way around the newest iPhone update. Even though iOS 16 has a few new features, having more battery is a priority for all of us. So you can choose between the options you want to keep or eliminate to maintain your battery percentage.
