If your iPhone device is usually draining its battery while using it, or your smartphone is overheated without multitasking, then the issue is iOS 15.4. Many iPhone users have complained on different platforms that they face the battery draining problem after upgrading the device to 15.4.
We can understand that draining the battery is quite frustrating. Don’t worry. We are here to rescue you again. The problem may be caused by a bug named ‘duetexpertd.’ It uses iPhone resources without any need.
We will discuss how you can fix this issue in this guide. Let’s get started.
1. Restart Your iPhone
Once you notice that your smartphone is abnormally draining the battery after upgrading it to iOS 15.4, restoring your iPhone would be helpful. We recommend restarting your device without doing any other thing.
Power off your iPhone, wait for a few minutes, then turn it on. A quick restart can have an incredible impact on the performance of your device, so it would be better to try restarting your device first.
2. Check Your Device’s Apps
Your device applications, most probably third-party apps, tend to have some reactions whenever Apple releases a new iOS update. There is a high chance that one of those apps is causing the battery drainage issue. We suggest you check your device app’s performance on iOS 15. Searching for the app or apps causing issues will take only a few minutes.
Following are the steps you need to follow to do so:
- Head to the settings app.
- Select battery.
- Go to the Battery usage tool.
This tool will help you find apps causing battery drainage problems. You can simply uninstall that particular app and reinstall it.
3. Reset Device All Settings
Once you have realized that the apps are not causing the battery drainage issue, the next step you need to do is reset your smartphone’s settings. Remember that when you reset all the settings, you’ll lose some data, such as a WIFI password or Bluetooth connection. Make sure to note down the passwords before resetting the device.
For resetting your iPhone following are the instructions you need to follow:
- Head to Settings.
- Go to General.
- Scroll down and click on transfer or Reset iPhone.
- Hit on Reset.
- Tap on reset all settings and enter your pin code if you’ve one.
Once the procedure is complete, you’ll have to reset your passwords again.
4. Disable Unnecessary Widgets
Widgets are convenient for sending and receiving instructions with a single swipe. However, if your phone has more active widgets on the sidebar, it’ll consume much of your device’s battery. It happens because Widgets are the one that creates a load on the processor. You can disable widgets if they are no longer in your use. You can disable them by simply tapping on the red circle and removing it.
5. Turn On Airplane Mode
Enabling Airplane mode means your iPhone will disconnect from all the wireless devices, which helps save a lot of battery. Wireless services are the one that eats up your device’s battery a lot. You can try this fix on iOS 15.4 battery drainage issue.
6. Customize Displays On Your Device
If the auto-brightness features respond correctly, it is helpful. Otherwise, we can say it is just a battery waste. For instance, if the sensors are not answering correctly and brightness is at the top in the darkness, it’d be better to disable auto-brightness. Afterward, you can adjust the brightness according to your needs.
For doing so, the following are the steps you need to follow:
- Launch the Settings apps on your iPhone device screen.
- Tap on Display and Brightness and then turn off “Auto-Brightness.”
7. Enable Low Power Mode
You can enable low power mode on your iPhone device to fix battery draining issues. Many Apple devices have this feature to save battery life. Low power mode helps reduce the battery usage of your iPhone or iPad when the battery is low.
You can turn on or turn off low power mode through Settings. Tap on the battery and switch on or off low power mode. Furthermore, Apple has introduced a feature that will tell you a list of attributes whose operations will be reduced when the low power mode is on.
8. Disable Raise To Wake
For activating the screen automatically, raising to wake is an intelligent way to do so. However, the iPhone cannot recognize the intentional and unintentional Raise to wake, which can affect the battery life.
You can turn this feature off by following the listed instructions:
- Go to settings.
- Select Display and Brightness.
- Power off the switch for Raise to wake.
9. Reduce Screen Motion
Another thing that consumes your device’s battery is small animation. You might want to reduce screen motion to save battery life on your iPhone.
Here are the steps you need to follow:
- Go to Settings.
- Scroll and Tap on Accessibility.
- Select motion and turn on reduce motion.
Once Apple launches a new update, you can turn off the motion feature again to get the latest animations from your iPhone interface.
10. Back to Older Version
Sometimes, users can’t wait for the next iPhone update and want a quick fix. If you are one of those, we’ve got you covered. You can try downgrading back to an older update of the iPhone. Note one thing downgrading options change over time, and you might not find it because Apple stops logging in on older versions. Many users find this fix helpful as a quick fix. However, you have to lose some of the latest features.
