Combating the Heat: Solutions to Fix iPhone 12 Overheating

Solutions To Fix Iphone 12 Overheating

Before resorting to drastic measures, let's explore some readily available solutions:


Swap the Substandard Case

Numerous inexpensive and bulky cases lack heat dissipation, leading to overheating problems. Ensure your case boasts enhanced heat reduction to maintain device coolness. Explore our curated collections of top iPhone 12 series cases, covering clear, bumper, stylish, and leather options. For improved heat dissipation, please browse through our selections.


Opt for MFi Certified

Chargers Using MFi (Made for iPhone, iPad, and iPod) certified chargers is imperative for several reasons. Firstly, certified chargers ensure full compatibility, enabling faster and more efficient charging for your iPhone. Secondly, authorized chargers are better equipped to handle potential threats such as overheating, overcurrent, and short-circuiting.


Conversely, fake or uncertified chargers offer slow charging and are prone to issues like overheating and short-circuiting. They can also trigger the "Accessory may not be supported" error. Hence, it's crucial always to steer clear of uncertified chargers.

 

Adjust Settings:

  • Reduce Brightness: A brighter screen consumes more power and generates more heat. Lowering the screen brightness can significantly help.
  • Disable Background App Refresh: This stops apps from continually refreshing in the background, minimizing battery usage and heat production. Navigate to Settings > General > Background App Refresh, then toggle it off for individual apps or altogether. 
  • Disable Location Services for Unnecessary Apps: Many apps don't require constant location access. In Settings > Privacy > Location Services, deactivate location services for apps that don't need them.
  • Manage Bluetooth and Wi-Fi: If you're not actively using Bluetooth or Wi-Fi, turn them off to conserve battery and reduce heat generation.

Control App Usage:

  • Identify Resource-Heavy Apps: Monitor battery usage to pinpoint apps that consume excessive power. Go to Settings > Battery and check the list. Consider limiting usage or finding alternatives for power-hungry apps.
  • Force Quit Idle Apps: Close apps you're not actively using by swiping up on them in the App Switcher (double-click the Home button or swipe up from the bottom on newer iPhones).

Software Updates:

  • Install the Latest iOS Update: Outdated software can sometimes contain bugs contributing to overheating. Keeping your iPhone updated with the latest iOS version ensures optimal performance and addresses potential issues. Navigate to Settings > General > Software Update to check for and install updates.

Storage Management:

  • Free Up Storage SpaceA cluttered device can impact performance and lead to overheating. To free up space, offload unused apps, delete unnecessary photos and videos, and utilize iCloud storage for backups—go to Settings > General > iPhone Storage for a detailed breakdown.

Advanced Solutions for Persistent Heating Issues

Advanced Solutions For Persistent Heating Issues

If the essential solutions don't resolve the overheating problem, consider these advanced troubleshooting methods:


Reset All Settings:

Resetting all settings to factory defaults can sometimes resolve software glitches causing overheating. This won't erase your data, but you must re-enter Wi-Fi passwords and customize some settings. Go to Settings > General > Reset > Reset All Settings.


Restore iPhone as New:

If a reset doesn't work, consider a full restore. This wipes all your data and settings, giving your iPhone a clean slate before backing up your data to iTunes, iCloud, or a third-party cloud storage service. This process can be done through iTunes on a computer or directly on your iPhone (Settings > General > Reset > Erase All Content and Settings).
