Why Is Your iPhone Overheating

When you’re charging your iPhone, scrolling through social media, or on a video call, your iPhone is getting very warm. You may initially think nothing of it. But if the phone begins to lag, lose charge, or display a temperature warning, then you have to take action.

Overheating of iPhones is an issue of great concern for Australian iPhone users especially during the hot summer months. While it is normal for your iPhone to be warm at times, when it becomes overly hot this will have negative effects on the way your iPhone functions, the health of its battery, and the general dependability of your device.

Why do iPhones become hot even when they’re used very little? Here’s an overview of the typical reasons for this issue, as well as warning signs and effective ways to help maintain the performance of your device.

Is It Normal for an iPhone to Get Hot?

An iPhone gets warm during use as a result of doing a large amount of tasking. For instance, recording high-definition video, downloading large amounts of data/programs, updating the device’s software (iOS) and/or using a wireless charging station will cause an iPhone to become warm.

Apple states that the operating temperature range for the iPhone is 0°C – 35°C. Excessive exposure to high temperatures may shorten the lifespan of your battery, and negatively affect the performance of your device.

However, occasional warmth doesn’t necessarily mean your phone needs repairs.

The issue of the phone getting hot while being used normally can cause users pain in their hands, or cause the device to turn off on multiple occasions.

7 Common Causes of iPhone Overheating

1. Too Many Power-Hungry Apps

Running demanding applications can make your iPhone’s processor work harder.

When you are playing games on your computer, editing video files, using the GPS system to find where you want to go, and making long-distance video calls, your computer generates a lot of heat because it requires a great deal of CPU processing.

In addition, some applications will keep running in the background after you close them.

What you can do:

Go to the battery menu under settings to determine if there are any applications that use too much power. Update applications that have problems, limit the use of background activities from other applications, and close down applications that begin to act abnormally.

2. Using Your iPhone While Charging

Have you noticed your iPhone getting hot while charging?

Natural charging produces heat. Playing games, using GPS, and streaming video at the same time will produce more heat due to an increased work load.

Compared to most wired charging scenarios, wireless charging can be a source of heat.

For optimal temperature regulation, charge your iPhone on a firm, well-ventilated area and do not engage in resource-intensive tasks while it is being charged. Get details on Smartphone Software Problems Repair

3. Direct Sunlight and Australian Summer Heat

Australia’s hot summer conditions can quickly increase an iPhone’s temperature.

For example, leaving your phone out in direct sunlight such as on a car dashboard, on an outdoor cafe table, or on a window sill will expose it to extra heat.

In addition to the previous points, the combination of screen brightness, GPS activity and direct sunlight when using navigation in your car may also create a dangerous situation.

Therefore, keep your device shaded and avoid leaving it inside parked vehicles.

4. Battery Ageing or Damage

As batteries age they may not provide consistent power. Therefore, you are likely to notice inconsistent performance with your device, such as unexpected power failures, shorter battery life than usual, and/or other forms of erratic behavior.

A reduction in battery performance is unlikely to cause a problem with temperature. However, if your device’s battery is either faulty or malfunctioning, it may experience problems related to heat.

You can find out how your iPhone’s battery is doing by going into Settings, clicking on Battery, and selecting Battery Health (or Battery Health & Charging) based upon which model you have.

Your cell phone is running too hot and the battery is dying faster than usual, then you need to have a professional evaluate the battery. Looking For a Smartphone Button Repair Service

5. Software Bugs and iOS Updates

Sometimes, the problem starts immediately after an iOS update.

It is possible for your iPhone to do background indexing, photo processing or other system tasks after you install an app. This is why it is normal for your iPhone to become warm temporarily.

However, poorly optimized applications or software issues may result in increased use of the computer’s CPU.

Update both iOS and all of your installed apps. If the iPhone is still overheating once the background processes have slowed down, it may be time to look into what else could be causing the issue instead of continuously resetting the phone.

6. Poor Mobile Network Reception

The weaker the mobile signal is, the more likely it is that you will experience higher levels of battery drain. This is due to the fact that when there’s less signal, the iPhone has to work harder to stay connected.

For example, the demand for parking in underground parking garages, remote locations, and buildings that do not have good cell service could increase.

In addition, long video calls and/or mobile hotspot usage in areas with weak cellular coverage can cause an increase in temperature.

Connect to a dependable Wi-Fi network as often as possible to prevent excessive use of your phone’s cellular data through hotspots.

7. Faulty Charging Accessories or Internal Components

Not every overheating problem comes from software.

When a device gets too hot, it may be due to damaged charging cables, faulty power supplies, a bad battery, or some problem inside the device’s electronics.

Electrical problems can result from liquid damage or previously sustained physical damage.

A professional diagnostic can help identify whether the problem stems from your phone’s battery, charging system, or another component which is creating the heating issue.

How to Cool Down an Overheating iPhone Safely

If your device becomes unusually hot, take action before continuing normal use.

  • Disconnect the charger: Stop charging until the device cools.
  • Move away from sunlight: Choose a shaded, dry indoor location.
  • The phone case must come off. Removing the phone case will help reduce the amount of heat that is created by the case.
  • Stop demanding applications: Pause gaming, streaming and navigation.
  • When a temperature warning displays on your device’s screen, turn off your device to allow it to cool down.
  • Once the phone has had time to cool, you will be able to tell if there is an application that uses significantly more battery power than usual.
  • Seek repairs if needed: Repeated overheating deserves professional attention.

Do not put your iPhone in a refrigerator or freezer without first warming it up. Rapidly changing the temperature can result in condensation inside the iPhone, and could possibly damage the internal parts of the iPhone.
