Users can try some energy-saving measures, such as closing some unnecessary background applications, reducing screen brightness, etc., to reduce the energy consumption of the device. If the problem persists, it is recommended to contact Apple customer service for further assistance.

When encountering the serious problem of heating and power consumption in iOS 16, we need to know what is causing it. Generally, serious heat and power consumption in iOS 16 may be caused by the following reasons: first, too many background running applications; second, excessive use of the CPU and GPU; third, system or application errors. In order to solve this problem, we can take the following measures: first, close unnecessary background programs; second, reduce the use of high-performance applications and functions; in addition, update and restart the system to fix system or application errors. By taking these measures, we can effectively solve the problem of serious heat and power consumption in iOS 16.

The following are the reasons and solutions for serious heating and power consumption in iOS 16: iOS 16 is a powerful operating system, but sometimes serious problems of heating and power consumption may occur during use. This is mainly due to the following reasons: 1. Too many background applications: If you run many applications at the same time, these applications will occupy a lot of system resources, causing the device to heat up and consume power. The solution is to close unnecessary background applications and keep only the essential ones running. 2. System update issues: Sometimes, system updates may cause the device to heat up and consume power. This may be due to some bugs or imperfect code. The solution is to wait for the official release of a patch or upgrade to the latest version of the system. 3. Excessive push notifications: Push notifications may cause frequent vibrations and screen lighting on the device, causing the device to heat up and consume power. The solution is to check and disable unnecessary push notifications and keep only the important ones. 4. High brightness and backlight settings: High brightness and backlight settings consume a lot of power, especially if the brightness and backlight are kept high for a long time when using the device. The solution is to turn down the screen brightness or use the automatic brightness adjustment function. 5. Application problems: Some applications may have code problems or excessive use of system resources, causing the device to heat up and consume power. The solution is to uninstall or update these applications, or contact the developer for a solution. To sum up, to solve the serious problem of heating and power consumption in iOS 16, we can close unnecessary background applications, wait for system updates or upgrade to the latest version of the system, disable unnecessary push notifications, lower the screen brightness, uninstall or update existing Problem application. I hope the above solutions can help everyone solve the problem of serious heating and power consumption in iOS 16.

1. Software update

After the new system is launched, third-party software needs to be updated to adapt to the new system. Failure to update may cause the software to crash or some functions to become inoperable. When users upgrade their systems, if they do not turn on automatic software updates, they are likely to encounter problems such as software incompatibility, inability to open, or crashes. However, for users who have automatic updates turned on, the App Store will silently download new versions of the software in the background. This process will cause increased power consumption and heat generation of the phone.

In order to solve the problems caused by automatic software updates, we can take the following methods: 1. After upgrading the system, temporarily turn off automatic software updates manually. This can avoid problems such as software crashes during the update process. 2. When encountering problems such as software crashes, you can manually enter the App Store to update the software. Manual updates can solve some software problems and ensure that the software is always up to date. 3. Before going to bed or other times when you are not using your phone, you can connect the charger and turn on automatic software updates. This allows the software to stay up to date without affecting its use, providing a better user experience. Through the above methods, we can effectively solve a series of problems caused by automatic software updates, and ensure that the software always maintains the latest version, providing users with a better user experience.

2. App background activities

According to Apple’s official support document, when we update the system (software update), built-in applications such as photos will re-index or re-analyze data. For example, after upgrading to iOS 16, the system added a new feature called "Duplicate Items", and the system will reanalyze and classify photos in the background. This is also the reason why some users cannot see the "Duplicate Project" function after the upgrade is completed, and the phone will experience heat and reduced battery life.

The system will automatically perform this process after completing the update, and users cannot modify it. Therefore, it is recommended to perform system upgrades before going to bed or at night, or during a period when you do not need to use your phone. If you accidentally upgrade the system during normal times, it is recommended to turn on low power mode after the upgrade is completed. The system will automatically limit background activities to reduce heating and power consumption issues.

3. Siri and Search

Once the system update is completed, iOS 16 will re-establish the index focusing on the search function. The focused search function of iOS 16 can search for more image results from apps such as information and files on the home screen, provided that the system needs to create an index in advance in the background. If more software is installed and the amount of data is larger, the background running time will be longer, and it will also be easier for users to feel the problems of heating and battery life after upgrading the system.

Therefore, after updating the system, it is recommended to go to the "Siri and Search" option in "Settings" and turn off related settings such as "Show App in Search" in each application. This can prevent personal privacy-related information from appearing in search results and improve information security.

4. Charging

Before performing a system update, we will usually receive a prompt to connect the iPhone to the power source and ensure that the battery level is greater than 50%. In daily use, mobile phone charging (especially wireless charging) will generate a certain amount of heat. When the system is updated, the hardware will operate at high speed and will also generate heat. Therefore, users will obviously feel that the phone heats up during charging and system updates.

When you want to update your phone, I recommend you use wired charging and temporarily remove the phone case. In addition, if conditions permit, you can also consider installing a cooling back clip to help dissipate heat from the phone. This prevents the phone from overheating during the update process and protects the phone's battery life and performance.

5. New Features

After upgrading to a new system, some new features are often brought. After the lock screen wallpaper in iOS 16 is updated, the lock screen widgets are added. Support will also increase power consumption; the new input method vibration feedback in iOS 16 will also affect battery life to a certain extent because it requires the vibration motor to be called.

Therefore, in the early stage after upgrading the system, we can appropriately turn off or reduce the use of new functions to reduce heat generation and power consumption.

6. Mobile phone performance and battery health

The new version of iOS launched every year will have some restrictions, so that only some mobile phone models can be upgraded to the latest system. iOS 16 is no exception. This is because the processor and other hardware of the old iPhone are relatively old and may not be able to support the new iOS system. Even if you upgrade, there may be issues with phone heating and reduced battery life due to insufficient performance. Therefore, Apple has restricted the upgrade rights of some older iPhones to ensure that users can get the best experience after upgrading.

For some older mobile phones, we recommend not to upgrade them unnecessarily. The same goes for battery health. The lithium batteries used in iPhones have a certain service life. As time goes by, the battery life will gradually shorten, resulting in a reduction in the battery life of the phone. Therefore, we should use mobile phones carefully and avoid frequent charging and excessive use to extend the life of the battery.

If you want to downgrade iOS 16 to iOS 15, you can use the iOS downgrade function in the Apple Phone Repair Tool. The standard downgrade mode preserves data and does not cause problems such as white apples. In addition, the tool also supports repairing 150 common iPadOS system bugs. The operation is very simple, and the downgrade can be completed with just one click.
