Reports have emerged that some iPhone users who recently updated their devices to iOS 16.4.1 are experiencing heating issues. This iPhone overheat issue is said to be specific to those who use wireless charging to power up their devices. Despite these reports, it is still recommended that iPhone users upgrade to the latest iOS version, as it includes crucial security patches and performance improvements.

What is the iPhone Overheat Issue post iOS 16.4.1 update?

According to a recent report by ZDNet, some iPhone 14 Pro and iPhone 14 Pro Max users have reported experiencing heating issues and crashes after updating to iOS 16.4.1. These issues appear to be most prevalent after wireless charging, with some devices reaching temperatures as high as 39.1 degrees Celsius. It was also discovered that iPhone kept for an overnight charge did not get fully charged.

It is important to note that while these reports may be concerning for some users, they do not necessarily reflect the experience of all iPhone 14 Pro and Pro Max users who have updated to iOS 16.4.1. It is possible that the issues are related to specific hardware configurations or usage patterns.

However, other models like iPhone 11, iPhone 12 series, and iPhone 13 series are also reporting iPhone overheat issues after updating to the latest iOS 16.4.1 version.

Though, it’s common knowledge that following an iOS update iPhone usually slows down and feels hotter than usual. It’s because of a lot of indexing and cache building after an update happens. But after almost a week of use, the update has not solved the iPhone overheat issue.

After the release of iOS 16.4.1 on April 7, Apple stopped signing iOS 16.4, which means that users can no longer downgrade to the previous version of iOS once they have updated to iOS 16.4.1. This means that if a user encounters any issues or bugs after updating to iOS 16.4.1, they will not be able to downgrade to the previous version of iOS 16.4.

Therefore, it is always a good idea to backup your device before updating to the latest version of iOS, and to make sure that your device is compatible with the new update. Users should also ensure that they have enough storage space on their device to accommodate the update and that their device is fully charged or connected to a power source during the update process.

Why should you update to iOS 16.4.1?

iOS 16.4.1 update includes fixes for two critical security vulnerabilities that could potentially leave devices vulnerable to exploitation.

The first vulnerability fixed in the update is related to the iOS kernel, which is the core of the operating system that controls how software interacts with hardware. The vulnerability allowed malicious apps to gain elevated privileges, which could potentially allow them to gain access to sensitive data on the device.

The second vulnerability addressed in the update is related to WebKit, the browser engine used by Safari on iOS. The vulnerability could allow attackers to execute arbitrary code on the device by tricking the user into visiting a malicious website.

Overall, these security vulnerabilities could have serious consequences if left unpatched, and it is, therefore, crucial that users update their devices to iOS 16.4.1 to ensure their devices are protected against potential security threats.

In addition to the security fixes, the latest iOS update, iOS 16.4.1, also includes new variations of the “pushing hands” emoji to better represent a wider range of skin tones. This is part of Apple’s ongoing efforts to promote diversity and inclusivity in its products.

The “pushing hands” emoji is often used to represent the practice of tai chi, which is a traditional Chinese martial art form. With the latest update, users can now choose from a total of 25 different skin tone variations for this emoji, ranging from the lightest to the darkest shades.

This update is a positive step towards promoting greater representation and inclusivity in emoji usage, and it is likely to be welcomed by many users around the world.

In addition to security fixes, and emoji enhancements, the latest iOS update has also fixed a Siri bug that forced it to become unresponsive.

How to fix iPhone Overheat issue post iOS 16.4.1 update?

It’s always a good idea to take steps to prevent potential issues with your device. If you’re experiencing heating issues or other problems with your iPhone after updating to iOS 16.4.1, there are a few things you can do to minimize the risk of the problem happening again in the future

Tip 1: Opt for Wired Charging

You are correct that switching to wired charging does not completely eliminate overheating, but it can help to reduce the amount of heat generated during charging. Wired charging typically generates less heat than wireless charging, especially if you are using an Apple-certified charger that is compatible with your device.

While wired charging can help to reduce the risk of overheating, it’s also important to make sure that your device is not covered by any material that could block airflow and to avoid using your device while it’s charging. This can help to further reduce the risk of overheating and prolong the lifespan of your device’s battery.

Tip 2: Force Close Unused Apps

Force-closing unused apps can help to reduce the workload on your iPhone’s processor and prevent it from overheating. When you open an app on your iPhone, it runs in the background and continues to use system resources until it is fully closed.

To force-close unused apps on your iPhone, follow these steps:

  1. Swipe up from the bottom of the screen to access the App Switcher.
  2. Swipe left or right to locate the app that you want to close.
  3. Swipe up on the app preview to force it to close.

Repeat this process for each app that you want to force-close. Keep in mind that force-closing apps may not always be necessary and that closing certain apps could actually have a negative impact on performance. In general, it’s a good idea to only force-close apps that are causing issues or taking up a significant amount of system resources.

Additionally, you may want to consider using the “Offload Unused Apps” feature in your iPhone’s settings. This feature automatically removes unused apps from your device while keeping their data and documents intact. To enable this feature, go to Settings > General > iPhone Storage > Offload Unused Apps and toggle the switch to on.

By force-closing unused apps and using the “Offload Unused Apps” feature, you can help to reduce the workload on your iPhone’s processor and prevent it from overheating.

Cases can prevent the iPhone from properly dissipating the heat that is being generated during charging, which can lead to overheating issues. Removing the case while charging can help to improve airflow and reduce the risk of overheating.

To remove the case from your iPhone, simply locate the small opening or seam where the case meets the device and gently pull the case away from the device. Be careful not to apply too much force or use any sharp objects that could damage the case or the device.

It’s also important to make sure that your iPhone is not covered by any other material, such as a blanket or cushion, that could block airflow and contribute to overheating. Placing your device on a flat, hard surface while charging can help to improve airflow and reduce the risk of overheating.

Tip 3: Remove the Charging Case

It’s possible that there may be an underlying hardware issue that is causing the overheating, which may require professional repair or replacement.

Tip 4: Reduce the Processor Load

Reducing the processor load on your iPhone can help to prevent overheating. When your iPhone’s processor is running at full capacity, it generates a significant amount of heat, which can cause your device to become uncomfortably hot to the touch.

Here are some tips for reducing the processor load on your iPhone:

  1. Close unused apps: As we discussed earlier, force-closing unused apps can help to reduce the workload on your iPhone’s processor and prevent it from overheating.
  2. Disable background app refresh: Background app refresh allows apps to continue running in the background even when you’re not actively using them, which can cause your processor to work harder than it needs to. To disable background app refresh, go to Settings > General > Background App Refresh and toggle the switch to off for any apps that you don’t want running in the background.
  3. Reduce screen brightness: The brighter your iPhone’s screen, the more power it uses and the harder your processor has to work. Try reducing your screen brightness to the lowest comfortable level to reduce the workload on your processor.
  4. Disable location services: Location services allow your iPhone to determine your location using GPS and other sensors, which can be a drain on your processor. To disable location services, go to Settings > Privacy > Location Services and toggle the switch to off for any apps that don’t need to know your location.

By reducing the processor load on your iPhone, you can help to prevent overheating and extend the life of your device.

Tip 5: Setup a Day Time Charging routine

Avoiding overnight charging can help to reduce the risk of overheating in your iPhone. Charging your device several times throughout the day, rather than leaving it plugged in overnight, can help to prevent the battery drain and prolong its lifespan.

To charge your iPhone multiple times throughout the day, you can use a portable charger or carry a charging cable with you so that you can plug in your device when it needs a boost. Apple also offers a feature called “Optimized Battery Charging” that can help to reduce the amount of time that your device spends at 100% charge, which can help to reduce the risk of overheating and prolong the lifespan of your battery.

To enable Optimized Battery Charging, go to Settings > Battery > Battery Health > Optimized Battery Charging and toggle the switch to on. This feature uses machine learning to learn your charging habits and avoid charging your device to 100% until just before you need it, which can help to reduce the amount of time that your device spends at a high temperature.

By avoiding overnight charging and charging your device multiple times throughout the day, you can help to reduce the risk of overheating in your iPhone and prolong the lifespan of its battery.

Tip 6: Hard Restart iPhone

You are correct that restarting your iPhone can help to alleviate many issues, including overheating. Restarting your device can help to clear out any processes or apps that are causing your iPhone to overheat, and can also help to refresh your device’s memory and system resources.

To restart your iPhone, follow these steps:

  1. Press and hold the power button on the side of your device.
  2. Swipe the “slide to power off” slider to the right to turn off your device.
  3. Wait for your device to fully shut down, then press and hold the power button again until the Apple logo appears.

Once your iPhone has restarted, check to see if the overheating issue has been resolved. If the issue persists, try some of the other fixes we’ve discussed, such as switching to wired charging, taking off your case while charging, and force-closing unused apps.

Tip 7: Do a battery calibration

calibrating your iPhone’s battery can help to prevent overheating issues. Battery calibration involves fully charging your iPhone, then fully discharging it and charging it back up again. This process can help to reset your iPhone’s battery level indicator and ensure that it accurately reflects the actual state of your battery.

Here are the steps for calibrating your iPhone’s battery:

  1. Charge your iPhone to 100%: Plug in your iPhone and allow it to charge until it reaches 100%.
  2. Use your iPhone until it shuts down: Use your iPhone normally until it shuts down due to low battery.
  3. Charge your iPhone back up to 100%: Plug in your iPhone and allow it to charge back up to 100%.
  4. Restart your iPhone: Press and hold the power button on your iPhone until the “slide to power off” slider appears. Slide the slider to the right to turn off your iPhone, then press and hold the power button again until the Apple logo appears.
  5. Check your battery level: After your iPhone has restarted, check the battery level to see if it accurately reflects the state of your battery. If your iPhone’s battery level still seems to be inaccurate or you are still experiencing overheating issues, you may want to contact Apple support or visit an Apple Store for further assistance.

Keep in mind that battery calibration is not a guaranteed fix for all battery-related issues, and it may not be necessary for all iPhone users. However, if you are experiencing overheating or other battery-related problems, it’s worth giving battery calibration a try to see if it helps.

Tip 8: Reset your network settings

Resetting your network settings can help to resolve connectivity issues and improve the overall performance of your iPhone. It can also help to prevent overheating issues that may be caused by network-related problems. Here are the steps to reset your network settings:

  1. Open the Settings app on your iPhone.
  2. Scroll down and tap on “General.”
  3. Scroll to the bottom and tap on “Reset.”
  4. Tap on “Reset Network Settings.”
  5. Enter your passcode if prompted, and confirm that you want to reset your network settings.
  6. Your iPhone will restart and your network settings will be reset.

Note that resetting your network settings will also remove any saved Wi-Fi passwords, so you will need to re-enter them when you reconnect to Wi-Fi networks. It will also remove any custom network settings, such as VPN configurations. However, resetting your network settings can often help to resolve network-related issues that may be causing your iPhone to overheat.

While it can be frustrating to use a warm device, it is still recommended to update to the latest iOS 16.4.1 as soon as possible, as it contains important security fixes. To avoid heating issues while charging, users can stick to wired charging instead of wireless charging, and avoid leaving their iPhone plugged in overnight. Additionally, using an Apple-certified charger and making sure it is not covered by any material that could block airflow can also help prevent heating issues. If you encounter any issues after updating, try the steps mentioned above, and if the issue persists, consider contacting Apple Support for further assistance.
