iOS 16 Battery Draining Quick, How to Fix? (Works on 16.4 and 16.5)

The release of iOS 16 by Apple has brought about many exciting features and changes. However, some users have reported experiencing a quick battery drain issue after installing the update. If you’re facing the same problem, there’s no need to panic. There are several ways to fix the fast battery consumption issue on your Apple device.

According to the Apple support team, fast battery consumption is a common occurrence after every major iOS upgrade. This is because apps and services undergo optimizations and changes in the background, which can result in rapid battery drainage. It typically takes up to 48 hours for things to settle down and for the battery consumption to stabilize. Therefore, if you have recently installed iOS 16 on your iPhone, it is recommended to wait for this period before taking any further action. In most cases, the issue will resolve itself once the device finishes its background optimizations. However, if the problem persists after the recommended time frame, you can apply the fixes listed below to optimize your battery life and ensure your Apple device continues to function at its best.

Reasons for Quick Battery Drain

There are several reasons why you may be experiencing a rapid battery drain on your Apple device. One common cause is a software bug that is consuming the battery in the background. Additionally, reduced battery health can also contribute to the battery draining issue. After every software update, the operating system optimizes all applications on your phone, which can result in increased battery consumption for certain processes.

Ways to Fix the iOS 16 Quick Battery Draining Issue

Solution 1: Restart Your iPhone

One of the simplest solutions to try when you notice your battery draining faster than usual is to restart your iPhone. This can help resolve any temporary software glitches that may be causing the battery drain.

To restart your iPhone, follow these steps:

1. Press and hold any volume and side buttons simultaneously until a slider appears on the screen.
2. Slide the slider to the right to turn off your iPhone.
3. Hold the side button until you see the Apple logo, indicating that your device is restarting.

Solution 2: Check the Battery Usage of Apps

If you have noticed a significant increase in battery consumption, it is essential to identify which apps are using the most power. By checking the battery usage of individual apps, you can determine if any specific app is responsible for the quick battery drain.

To check the battery usage of apps on your iPhone, follow these steps:

1. Open the Settings app.
2. Scroll down and tap on “Battery.”
3. Tap on “Last 10 Days” to view the battery usage of apps over the past ten days.
4. Look for any apps that have a significant percentage of battery usage but haven’t been used excessively. These apps may be the culprit behind the battery drain. Consider uninstalling them if they are not essential to your daily usage.

Solution 3: Disable Background App Refresh

Background App Refresh is a feature in iOS that allows applications and games to refresh their content in the background. While this feature can be useful, it can also contribute to excessive battery consumption, especially for non-essential apps. By disabling Background App Refresh for unnecessary apps, you can significantly improve your device’s battery life.

To turn off Background App Refresh for specific apps, follow these steps:

1. Open the Settings app.
2. Tap on “General.”
3. Select “Background App Refresh.”
4. Toggle the switch next to each app to the “Off” position for apps that you don’t need to run in the background constantly.

Solution 4: Improve Battery Health

Maintaining good battery health is crucial for optimizing battery life on your iPhone. If you notice a significant decrease in your battery’s health percentage, there are measures you can take to improve it.

To check the battery health percentage of your iPhone, follow these steps:

1. Open the Settings app.
2. Scroll down and tap on “Battery.”
3. Select “Battery Health.”

To maintain good battery health, consider the following tips:

• Turn On Optimized Charging: Charging your phone overnight can harm the battery’s health. To prevent this, enable the Optimized Charging feature. This feature stops charging your phone after reaching 80% and resumes charging just before you typically wake up.
• Avoid Draining the Battery Too Much: It is advisable not to let the battery percentage drop below 15%. Continuously using your device when the battery is below this recommended threshold can degrade its lifespan.

Solution 5: Install the Latest iOS Update

Sometimes, a new software update can introduce bugs that lead to battery drain issues. If Apple developers are aware of the problem, they may release a new update containing a fix for the battery drain issue. Therefore, it is essential to check for and install any available updates for your iPhone.

To check for new updates on your iPhone, follow these steps:

1. Open the Settings app.
2. Scroll down and tap on “General.”
3. Select “Software Update.”
4. If an update is available, tap on “Download and Install.” If no update is available, check for new updates after a couple of days.

Solution 6: Reduce Motion and Disable Location-Based Services

Certain features on your iPhone, such as motion effects and location-based services, can contribute to battery consumption. By reducing motion and disabling unnecessary location-based services, you can improve your device’s battery life.

To reduce motion on your iPhone, follow these steps:

1. Open the Settings app.
2. Scroll down and tap on “Accessibility.”
3. Select “Motion.”
4. Toggle the switch next to “Reduce Motion” to the “On” position.
5. To further disable animation, enable the toggle next to “Prefer Cross-Fade Transition.”

Disabling unnecessary location-based services can also help conserve battery life. To manage location settings, follow these steps:

1. Open the Settings app.
2. Scroll down and tap on “Privacy.”
3. Select “Location Services.”
4. Review the list of apps and services that have access to your location and disable unnecessary ones.

Solution 7: Turn Off Raise to Wake and Use Dark Mode

The “Raise to Wake” feature on your iPhone utilizes motion sensors to check if you’re actively using your device. While this can be convenient, it also consumes battery power. Disabling this feature can help extend your device’s battery life.

To turn off Raise to Wake, follow these steps:

1. Open the Settings app.
2. Scroll down and tap on “Display & Brightness.”
3. Toggle the switch next to “Raise to Wake” to the “Off” position.

Additionally, using Dark Mode can help conserve battery life. Dark Mode reduces the amount of power consumed by the display, resulting in improved battery performance.

Solution 8: Enable Low Power Mode

When your battery is draining quickly or when the remaining battery percentage is low, enabling Low Power Mode can be a helpful solution. This feature automatically reduces unnecessary background processes and animations, leading to extended battery life.

To enable Low Power Mode on your iPhone, follow these steps:

1. Open the Settings app.
2. Scroll down and tap on “Battery.”
3. Toggle the switch next to “Low Power Mode” to the “On” position.

By following these solutions, you can address the quick battery draining issue on your iPhone running iOS 16. Implementing these fixes will not only extend your device’s battery life but also ensure that you can continue to enjoy all the exciting features and improvements offered by the latest iOS update.
