Why Is iPhone Heating Up After Screen Replacement?

What could have been the problem when your iPhone began to get so hot after getting a screen replacement? Several users have complained that the heat was more concentrated at the top of the iPhone near the front-facing camera, whereas some others have said it was evenly distributed throughout the phone.

While it is more than uncomfortable to have a burning furnace as an iPhone, it also impacts your battery life so badly as it may barely be able to make it through even half a day on moderate use. As you may already know, heat will consume more energy. In this article, you’ll find out what actually had gone wrong as well as several solutions to apply to stop your iPhone from overheating.

 

Why iPhone Is Heating After Screen Replacement

More than one factor can result in an overheating iPhone. Overheating resulting from a screen replacement is just one of them and is marked usually by a concentrated heat coming off from the top of the device and could be felt from the front and back of your iPhone

The following reasons may include why your iPhone gets so hot with a new screen as well as possible fixes to get the issue resolved.

1. Poor Quality Replacement Screen

Replacing your iPhone screen with an inferior one will cause more harm than expected to your device. A bad screen will not pass the compatibility test and your iPhone will immediately repel it. One way to show the incompatibility is by getting so hot because one or more components on the screen do the meet the requirements of made for iPhone screens.

To tell if your iPhone screen is from a genuine manufacturer, you have to test how It displays a black image. Here what you can do; 

  • Open a black image on your iPhone
  • Zoom in to the maximum on the image 
  • If the screen remains black or doesn’t even look like it’s turned on, then you have a good screen, otherwise having several other colors apart from black is a good indicator that you’ve got a bad replacement screen.

To fix the overheating problem is to go for a better quality replacement screen from verified manufacturers. It can cost anywhere from $70 plus replacement fee.

 

2. Insulation Was Tampered With

Exposed metal to metal contact from a wrong replacement screen installation can cause your iPhone to overheat. Oftentimes, repair techs forget to replace the insulating stickers on the flex connectors. These stickers prevent any metal to metal contact with the cover plate, hence, preventing any heat outbursts.

If you’re the one making the repair or a repair tech is taking on the duty, ensure to inspect if the insulation is properly replaced just before the iPhone is coupled back. The insulators are black in color, thin and made from a little bit of foam, so it should not be difficult to recognize.

 

3. Camera/Earpiece Assembly Placed Wrongly

If the camera and earpiece assembly gets to sit wrongly after screen replacement, then it is likely your iPhone will overheat. Usually, overheating after a screen replacement is associated with the earpiece not working, the camera not working or both.

If this is your case then you need to to make sure they’re placed the exact same way they came off from the factory. Also be careful while readjusting the assembly, because the connector flex is fragile and will be damaged even without you knowing with the slightest of strain on it. 

 

4. Damaged Camera Flex

The Front-facing camera flex when damaged during a screen replacement will cause your iPhone to overheat. Extreme care must be taken to ensure the camera connector cable is not pushed around more than it can bear during a screen replacement. Many repair techs do not yet know this. 

Unfortunately there’s nothing you can do to get the camera flex repaired once it gets damaged, the only thing you can do is to buy a replacement camera flex cable. It’s fairly cheap and will cost less than $20.

 

Why Is My Brand New iPhone Getting Hot?

A new iPhone is supposed to be at the peak of its performance since it is just like a new car engine and most importantly, you’re the first to ride on it. It’s no doubt a frustrating thing to experience that the iPhone you paid a fortune to own begins to overheat and sometimes even without a cause.

While several things could be responsible for your brand new iPhone overheating, mostly software, it’s important to make sure your iPhone has not suffered any hardware issue lately. 

For instance, if you had your iPhone fall into water, then that may be the culprit. In such a case, you’ll need a hardware repair and in most cases replacement of affected components. Below are the most probable culprits causing your new iPhone to overheat.

1. Multitasking With A Lot Of Apps

Multitasking with several apps opened all at once and being able to switch them at will is a great option but it does play a role in heating up your iPhone. Think of your iPhone as a car and the processor chip as the engine. 

The chip can get really busy as you continue to open and use more apps. Due to the workload on it, it’ll heat up really quick and the temperature will eventually be distributed to the rest of the iPhone components by conduction.

What you can do is to close out all apps currently opened on your device. Here’s how;

  • Swipe from the top or bottom of your iPhone depending on the model you have to open the multitasking window.
  • If your iPhone has a home button, double tap on it and the multitasking window will appear
  • Swipe up on each app to remove them one after another.
  • Restart your iPhone and verify if the phone still gets hot.

 

2. Some Apps Are Using Way To Much Battery Life

Some apps are really selfish when it comes to battery usage. This is however because of the processes they initiate on your device. The developers of the app are to be blamed at times too for making heavy duty apps that could have been simplified for optimized battery usage.

You may find that just one or a couple of apps are combining to drain your battery life quickly. Bear in mind that the quicker your battery drains, the more heat is produced from the battery region which spreads all over on your iPhone.

To see which app is using the most battery, follow the below guide;

  • Open settings
  • Tap on battery
  • Discover the apps draining more battery and exit them

 

3. Location Service Is Set To Always Active On Apps

Location services will keep working on your iPhone background, using cellular or WIFI data as well as a certain amount of battery life. Apps too can have your permission to keep track of your location per time and the more apps with location services set to always on, the more your iPhone will heat up. 

To turn off location service for apps that are irrelevant, here how;

  • Open settings
  • Tap on privacy
  • Tap on location services
  • Make sure the location service is toggled on
  • Scroll down to the apps
  • Tap on the app and select never to prevent the app from using location services on your iPhone.

Random bugs are the chief of many malfunctions on your iPhone. They could be from several sources, the most common of them are from Apps.

  • Tap on updates next to the app or tap update all.

Can A Cracked Screen Cause Overheating?

A cracked screen can potentially cause overheating. Two things, if the intensity of the crack is so bad, especially when it happens towards the top of the screen near the front-facing camera/proximity sensor and when debris begins to make its way into the internal components, it can be a problem.

A Mechanical damage that cracks the screen and affects the camera/earpiece assembly will result in overheating. On the other hand, over time several foreign dirt particles can easily slide into the internal parts of the iPhone and may damage a thing or two. This happening will also result in your iPhone overheating.

Can Overheating The iPhone Damage The Screen?

So much heat coming off an iPhone may be able to damage a phone screen but that will not happen on an iPhone. Apple has incorporated a safety feature against high temperatures on the iPhone that triggers software to shutdown the device in the event of high temperatures. 

However note that for your iPhone to go off to cool when its temperature rises beyond normal range doesn’t mean it has actually reached the overheating temperature, in fact, the shutdown strategy is to prevent it from overheating when the iPhone gets too warm.

 

Conclusion

A lot of problems can ensue from getting a screen replacement. That’s not to say you should continue using your iPhone with the screen cracked but to take extra care in choosing the right screen for your iPhone as well as having it fixed by an experienced repair tech. 

Your best option is the repair professionals at the Apple genius bar. Simply book an appointment with them and have your screen replaced for a small fee or pay nothing if you still have your warranty active.
