iPhone Overheating: Why It Happens and How to Fix It

Your iPhone is hot to the touch. Before you panic, most overheating is temporary and fixable in under five minutes. But some cases signal a real problem — a degraded battery, a software bug, or a device that needs service.

Here's how to tell which situation you're in, and what to do about it.

iPhones generate heat. That's normal. But when it's uncomfortable to hold or your phone displays a temperature warning, something specific is driving it.

1. Heavy processor load

Gaming, video recording, long FaceTime calls, or restoring from a backup all push the A-series chip hard. The phone gets warm — that's physics. It should cool down within minutes of stopping.

2. Background apps running hot

A single buggy app can spike your CPU even when you're not actively using it. Social media apps and navigation apps are common culprits. Go to Settings > Privacy & Security > Location Services and check which apps have "Always On" — that's your likely suspect.

3. Software bug after an iOS update

New iOS versions frequently cause temporary overheating for 24–48 hours post-install as the system re-indexes and re-syncs. If this started right after an update, wait a day before troubleshooting further.

4. Degraded battery

Lithium-ion batteries lose efficiency over time. As capacity drops, the battery works harder to deliver the same power — generating more heat. Check Settings > Battery > Battery Health & Charging. Below 80% is the threshold where degradation starts affecting performance.

5. Environmental heat

iPhones are rated for use between 0° and 35°C (32° to 95°F). Leave one on a car dashboard in summer and it will overheat. Always.

This is the question that matters most.

Probably normal:

• Warm during video streaming, gaming, or navigation
• Warm during initial setup or post-update
• Warm while charging (especially fast charging)
• Cools down within 5–10 minutes of stopping

Get it checked:

• Gets hot while doing nothing (idle overheating)
• Battery drains extremely fast alongside the heat
• Phone shuts itself off with heat warnings repeatedly
• The back of the phone is visibly warped or the screen is separating slightly from the frame
• You smell something burning

Stop using it immediately:

• Battery is bulging (the phone has a slight curve it didn't have before)
• You see smoke or sparks
• The device caused a burn

If any of the last three apply: power off, don't charge it, and contact Apple. File a report with the CPSC at https://www.saferproducts.gov if there was a safety incident (burn, smoke, fire).

Work through these in order. Most people are fixed by step 3.

1. Remove the case

Cases trap heat. Take it off and set the phone on a flat surface. Give it 5 minutes.

2. Close background apps

Double-tap the home button (or swipe up on Face ID models) and swipe away everything. On newer iOS: Settings > General > Background App Refresh > Off.

3. Disable location services for problem apps

Go to Settings > Privacy & Security > Location Services. Switch any non-essential app from "Always" to "While Using" or "Never."

4. Check for a software update

Go to Settings > General > Software Update. Apple regularly pushes patches specifically for thermal issues. Install if available.

5. Check Battery Health

Go to Settings > Battery > Battery Health & Charging. If you're below 80%, the battery is likely contributing. Apple's out-of-warranty battery replacement is $99 for most current iPhone models.

6. Reset all settings

This clears corrupted preferences without touching your data. Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. Takes about 5 minutes.

7. Restore as new (last resort)

If none of the above works, a full restore rules out a software corruption issue. Back up first.

Apple runs official repair and replacement programs when hardware defects are confirmed. These are separate from recalls — they're manufacturer-sponsored and usually free.

Active programs that may relate to heat or battery issues:

As of March 2026, Apple's service programs page (https://support.apple.com/service-programs) does not list an active overheating or battery recall for any current iPhone model.

Past programs (now expired):

• iPhone 6s and 6s Plus Unexpected Shutdown Program — expired
• iPhone 8 Battery Replacement Program — expired
• iPhone X Display Module Replacement Program — expired

These programs ended years ago and Apple is no longer accepting service under them.

What to do: Even without an active program, Apple will service your battery out of warranty for a flat fee. If your phone is still under the 1-year Apple Limited Warranty or AppleCare+, battery issues caused by defects are covered at no charge. Check your coverage at https://coverage.apple.com.

Go to Apple first if:

• Your battery health is low and the phone runs hot
• The phone shuts down unexpectedly from heat
• You want a battery replacement or hardware inspection

Book a Genius Bar appointment at https://www.apple.com/retail/geniusbar/ or start a mail-in repair at https://support.apple.com/iphone/repair.

File with the CPSC if:

• The device caused a burn, fire, or smoke
• Apple has refused to address what appears to be a safety defect

Report at https://www.saferproducts.gov. CPSC uses these reports to determine whether a formal recall investigation is warranted.

Q: Is it normal for my iPhone to get hot while charging?

A: Some warmth during charging is normal, especially with fast charging or MagSafe. If it's uncomfortable to touch or triggers a temperature warning, unplug it, remove the case, and let it cool before continuing.

Q: My iPhone gets hot after an iOS update. Is it broken?

A: Probably not. iOS updates trigger background re-indexing, photo re-analysis, and iCloud syncing — all CPU-intensive. Give it 24–48 hours. If it's still running hot after that, check for a follow-up iOS patch.

Q: Does Apple have a recall for iPhone overheating?

A: As of March 2026, there is no active Apple recall or service program specifically for iPhone overheating. Past battery programs (iPhone 6s, 8) have expired. Check https://support.apple.com/service-programs for the current list, or set up a RecallRadar alert to be notified automatically.

Q: My iPhone battery health is at 75%. Could that be causing the heat?

A: Yes. A degraded battery works harder to deliver power, generating more heat as a side effect. Apple's battery replacement service ($99 out of warranty for most models) is worth it if you're below 80% and experiencing thermal issues.

Q: When should I stop using my iPhone due to heat?

A: Stop immediately if the battery is visibly bulging, if you see or smell smoke, or if the device caused a burn. Power it off, do not attempt to charge it, and contact Apple and the CPSC.
