iPhone 15 overheating while charging: what to check

iPhone 15 overheating while charging: what to check. If your iPhone 15 overheating while charging has started worrying you, you’re not alone. Many users across Australia notice their phone getting unusually warm during charging, especially with newer models. While a little warmth is normal, excess heat should never be ignored. Over time, overheating can damage the battery, slow performance, and shorten your phone’s lifespan.

At Phone Repairs Wollongong, we see this issue daily. Thankfully, most causes are easy to identify and fix when you know what to look for. So, let’s break down exactly what causes the problem, what you can check at home, and when professional help becomes necessary.

Is It Normal for iPhone 15 to Heat While Charging?

Firstly, yes — mild warmth during charging is normal. Lithium-ion batteries generate heat while transferring energy. However, when your phone feels hot to touch, slows down, or shows temperature warnings, something isn’t right.

More importantly, Apple designs the iPhone 15 with advanced thermal controls. So when overheating occurs frequently, it often points to external factors or underlying issues.

Common Reasons for iPhone 15 Overheating While Charging

Understanding the cause makes fixing the issue far easier. Let’s look at the most common triggers.

1. Faulty or Non-Certified Charging Cables

One of the biggest reasons for iPhone overheating while charging is the cable itself. Cheap or non-certified chargers struggle to regulate power correctly.

As a result, excess energy turns into heat instead of charging efficiently.

What to check:

  • Use Apple-certified or MFi-approved cables

  • Avoid worn or frayed charging leads

  • Replace chargers older than two years

Even if a cable still “works”, it may no longer be safe.

2. Fast Charging Generates Extra Heat

Fast charging is convenient, but it also increases heat output. While the iPhone 15 manages this better than older models, charging too often at high wattage can cause overheating.

Therefore, if you notice heat buildup:

  • Switch to standard charging overnight

  • Avoid fast charging when the battery is already warm

Balance convenience with long-term battery health.

3. Background Apps Running While Charging

Another overlooked issue involves apps. Some applications continue working hard even while your phone charges. Games, video streaming apps, or navigation tools are common culprits.

Meanwhile, charging adds extra load, which pushes internal temperatures higher.

Simple fix:

  • Close unnecessary background apps

  • Avoid gaming while charging

  • Enable Low Power Mode if needed

This small change often makes a big difference.

4. Hot Environments and Poor Ventilation

Charging your phone in a hot room, car, or under pillows traps heat quickly. In Australia, summer temperatures make this problem even worse.

Because of that:

  • Charge in a cool, shaded area

  • Never place your phone under blankets

  • Avoid charging inside cars

Good airflow matters more than people realise.

5. Wireless Charging Heat Build-Up

Wireless charging looks neat, but it naturally generates more heat than wired charging. Misalignment or thick phone cases increase the issue further.

If overheating happens during wireless charging:

  • Remove the phone case

  • Align the phone properly on the pad

  • Switch back to cable charging

Wireless charging works best for short top-ups, not long sessions.

6. Software Bugs or iOS Issues

Sometimes the problem isn’t physical at all. Software bugs can cause background processes to overwork the system.

Therefore, always:

  • Update to the latest iOS version

  • Restart your phone regularly

  • Reset settings if overheating continues

Software updates often fix hidden performance problems.

7. Battery Health Problems

Although the iPhone 15 is new, battery defects still happen. Over time, damaged batteries struggle to regulate heat properly.

Warning signs include:

  • Battery draining unusually fast

  • Phone heating even when idle

  • Sudden shutdowns

In these cases, professional battery inspection is necessary.

Before visiting a repair shop, try these simple steps:
