How to Fix an iPhone 7 Heating Up After iOS Update

Have you noticed your iPhone 7 heating up after iOS update? Overheating issues are common after iOS updates. When an iPhone 7 overheats after an iOS update, it is often caused by excessive background activity or software glitches. To address this, we’ll guide you through steps such as closing background apps and resetting your device’s settings. These solutions can help alleviate the strain on your iPhone 7 and restore its optimal performance while keeping it at a safe temperature.

Why is My iPhone 7 Overheating After an iOS Update?

Here are the main reasons an iPhone 7 may get hot after an iOS update:

  • Indexing Photos and Media: The Photos app needs to re-index your entire media library after an iOS update. This processor-intensive task generates excess heat.
  • Downloading Apps and Updates: Your iPhone downloads app updates and new iOS components in the background after an update. This spikes CPU usage and causes overheating.
  • Apps That Are Incompatible: Some third-party apps may not be fully compatible with the latest iOS version. Using these apps strains the CPU and GPU, causing overheating.
  • Battery Issues: An aging or faulty battery can cause irregular power delivery, forcing the processor to overwork and overheat.
  • Hardware Problems: Defects with internal components like the processor or logic board can lead to inefficient heat dissipation.

Update iOS Software

Install the latest iOS updates which include fixes for bugs causing overheating in earlier versions. Go to Settings > General > Software Update.

Reset All Settings

Go to Settings > General > Transfer and Reset iPhone> Reset and choose Reset All Settings. Enter your passcode and confirm to reset settings. This clears any problematic settings causing overheating.

Check for Hardware Damage

If overheating persists, get your iPhone 7 inspected at an Apple Store for hardware defects like a faulty processor or damaged battery. These components may need to be repaired or replaced.
