iPhone 14 Overheating? How to Fix It
iPhone 14 running hot? Whether it's the base model, Plus, Pro, or Pro Max, here's how to cool it down and stop the overheating for good.
Why iPhone 14 Overheats
- iOS updates: Background re-indexing after major updates
- Always-On Display (Pro/Pro Max): Continuous display activity
- 5G connectivity: 5G radio generates significant heat
- Fast charging: 20W+ charging creates heat, especially in cases
- Gaming and video: A15/A16 chip under sustained load
- Direct sunlight: External heat compounds internal
- iCloud sync: Restoring or syncing large libraries

📋 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.
Quick Fixes
1 Remove Case and Cool Down
- Take off your case immediately
- Set face-down on a cool hard surface
- Do NOT put in fridge — thermal shock can damage components
- Allow 10-15 minutes to cool naturally
2 Turn Off Always-On Display (Pro Models)
AOD is a significant heat and battery contributor:
- Go to Settings → Display & Brightness
- Turn off Always On
- This alone can reduce chronic warmth significantly
3 Switch from 5G to LTE
- Go to Settings → Cellular → Cellular Data Options → Voice & Data
- Switch from 5G Auto to LTE
- Especially useful when indoors where 5G signal is weak
4 Stop Charging and Let It Cool
- Unplug if phone is warm while charging
- Don't use heavily while fast charging
- Charge overnight at ambient temperature without a case
Settings Adjustments
5 Enable Low Power Mode
- Go to Settings → Battery
- Enable Low Power Mode
- Reduces background activity significantly
6 Disable Background App Refresh
- Go to Settings → General → Background App Refresh
- Set to Off or Wi-Fi Only
7 Reduce Screen Brightness
- Swipe down from top-right to open Control Center
- Lower the brightness slider
- Enable Auto-Brightness in Settings → Accessibility → Display & Text Size
8 Update iOS
Apple released thermal fixes for iPhone 14 in several iOS 16/17 updates:
- Go to Settings → General → Software Update
- Install any available updates
9 Restart Your iPhone
- Hold Side + Volume Down until "slide to power off" appears
- Slide to power off
- Wait 30 seconds, press Side button to restart
10 Reset All Settings
If overheating persists with no clear cause:
- Go to Settings → General → Transfer or Reset iPhone
- Tap Reset → Reset All Settings
- Won't delete data — resets preferences only
