iPhone 15 Pro Overheating? How to Fix It
iPhone 15 Pro and 15 Pro Max had well-documented overheating issues at launch. Here's how to fix them — most are solved by iOS updates and settings changes.
The iPhone 15 Pro Overheating Issue Explained
When iPhone 15 Pro launched in September 2023, many users reported the phone getting uncomfortably hot — even during basic tasks like charging or browsing. Apple acknowledged the issue and released iOS 17.0.3 with a fix in October 2023.
If you haven't updated, update to the latest iOS first — it fixes the most common causes.

📋 Difficulty & Time
🔧 Fix Overheating: Step by Step
Step 1: Remove the Case
If you're using a thick case, remove it for 10 minutes. Plastic and silicone cases trap heat. If the device cools quickly without the case, switch to a thinner or vented case.
Step 2: Check for Background App Drain
Heat is usually a CPU/GPU symptom, not the cause. Settings → Battery → look at App Activity. Force-quit anything showing 30%+ background usage.
Step 3: Stop Charging While Using
Fast-charging while gaming / video calling generates heat from BOTH the SoC and the battery management chip. Stop charging when actively using; use Optimized Battery Charging at night.
Step 4: Check the Charger
Counterfeit USB-C chargers spike voltage and heat the battery. Use only Apple-branded or MFi-certified chargers. If your charger is hot to the touch while charging, replace it.
Step 5: Toggle Airplane Mode
If the device cools rapidly in Airplane Mode, you have a cellular signal issue — the radio is searching for towers and burning power. Re-toggle off; if heat returns, file a carrier ticket.
Step 6: Update iOS
Some iOS versions are notoriously hot. Apple has shipped patch updates specifically for thermal regression. Settings → General → Software Update.
Step 7: Clean the Speakers + Vents
Dust restricts heat dissipation. Use a soft brush + light compressed air to clear the speaker grilles and the vents on the bottom.
⚠️ Common Mistakes to Avoid
- Putting the device in the freezer (condensation causes liquid damage)
- Continuing to use during heat warnings (iOS will throttle, then shut down)
- Using counterfeit chargers that spike voltage
- Leaving the device in a hot car (>120°F can permanently damage the battery)
🏥 When to Call a Pro
If the device gets hot during idle (no apps, screen off), or shuts down spontaneously when warm, you have a hardware problem. Battery service is $99 (Apple) or $59–$89 (third-party). Logic board issues are diagnosed free at the Apple Genius Bar.
Known Causes
- iOS bugs: Early iOS 17 had thermal management issues (fixed in 17.0.3+)
- Third-party apps: Instagram, Uber, and Asphalt 9 had bugs causing excess CPU usage
- USB-C adjustment: First-time USB-C iPhone — some thermal tuning needed
- ProRes video: 4K ProRes recording is extremely demanding
- Titanium frame: Conducts heat differently than aluminum
- Initial setup: iCloud restore, app indexing, and updates
Fixes to Try
1 Update to Latest iOS — Do This First
- Go to Settings → General → Software Update
- Install any available updates
- iOS 17.0.3 and later contain thermal management fixes specifically for iPhone 15 Pro
2 Remove the Case While Charging
- Titanium conducts heat — cases trap it more than aluminum models
- Remove your case during charging sessions
- Charge overnight rather than rapid-charging during use
3 Check for Problematic Apps
Some apps had CPU bugs affecting iPhone 15 Pro specifically:
- Go to Settings → Battery
- Check which apps show high battery usage
- Update all apps — most fixed their bugs after Apple's disclosure
- If one app is consistently causing heat, delete and reinstall it
4 Limit ProRes Recording
- 4K ProRes at 60fps is the most demanding workload your phone can do
- Take breaks between long recording sessions
- Record in HEVC for day-to-day shooting, reserve ProRes for important work
- Use a cooling fan accessory for extended ProRes shoots
5 Disable Always-On Display (if enabled)
- Go to Settings → Display & Brightness
- Toggle off Always On
- The always-on display adds continuous power draw
6 Turn Off Background App Refresh
- Go to Settings → General → Background App Refresh
- Set to Off or Wi-Fi Only
7 Restart Your iPhone
- Hold Side + Volume Down, slide to power off
- Wait 30 seconds, then restart
- Clears stuck background processes
8 Reset All Settings
If overheating persists after updating:
- Go to Settings → General → Transfer or Reset iPhone
- Tap Reset → Reset All Settings
- This resets preferences without deleting data
