Have you ever seen a temperature warning pop up on a phone screen?

The icon shows a hot thermometer and reads, “Temperature, iPhone needs to cool down before you can use it”? This symbol indicates the software inside the phone reached too warm of a temperature to function safely. This happens for a few reasons.

• You left your phone in a hot area, perhaps a car in the middle of summer. The sun warmed up the iPhone and heated up the software, which could affect the phone’s hardwiring in the long term.
• You use your phone in too hot of temperatures. Maybe you’re trying to play Pokemon Go, texting a friend, and sending an email. If you scroll back and forth between all of these apps, the iPhone will try its best to respond to your needs, but if you do this in direct sunlight, the phone might quit working.
• Running a lot of apps in general, especially when they require a lot of phone battery, can drain the battery and overheat the system.
• A bad battery or a malfunctioning iPhone could have its wires crossed, causing the phone to overheat at inopportune moments.

Now that we know some root reasons that cause iPhones to overheat, let’s take a look at some reasons an iPhone could overheat while charging.

If you plug your iPhone into the power source and notice its temperature’s continual rise, the device could be overheating for multiple reasons.

A bad charger

This is a common reason that iPhones overheat. If a charger does not work properly, it could send the wrong signals to your iPhone, tricking the hardware and causing the phone to overheat.

To avoid this issue, make sure the charger is intact and the port is free of dirt and dust. If the cord appears twisted or tangled, unplug it, untangle it, and try to reinsert the plug into the phone. If that doesn’t fix the issue, try to plug the cord into a different outlet. If the phone continues to overheat after all of these fixes, it is time to get a new charging cord.

Internal issues

This problem occurs when either the iPhone battery or the software inside the iPhone is compromised. To check what is wrong with the phone, you will need to seek out a specialist who can assess the inside of the device.

Apple stores or Apple support can point you in the right direction. Sometimes iPhone batteries go bad, and you need to replace them with the help of a technician.

Temperature is a hazard

When an iPhone is in the presence of extreme heat, it issues a temperature warning to its users. This occurs whether or not a phone is charging, but if a phone charges in a hot room, the heat could make the phone overheat.

To circumnavigate this issue, make sure your outlets and your phone always charge in a cool, dimly lit space without much direct sunlight.

The phone needs an update

Sometimes iPhones overheat because they can’t keep up with internal hardware. This occurs when an older phone has not been updated for a while.

To make sure your iPhone stays updated, visit the updates bar in settings and regularly check for new updates.

Charging and using the phone too much

If you charge the phone too much, the charge won’t work properly. The system will get overloaded, and thus the iPhone will overheat. The same goes if you keep apps and programs open on your phone at all times.

This will cause the service to lag and the phone to overheat. To avoid this specific issue, make sure to charge your phone when it needs it and to close out all apps when you are done using them.

Above, we mentioned some reasons that cause an iPhone to overheat while charging. Sometimes you cannot get to the root of the overheating, but you want to stop the phone from warming up. Here are some trusted methods to use to stop your iPhone from overheating.

Before you do anything, make sure to unplug your iPhone if you notice it overheating while charging. Leaving it plugged in can cause damage to the internal hardware of the phone and the battery in the long run.

Reset your phone

A great way to stop a phone from overheating is by resetting all of its data. To reset your iPhone, visit the settings icon on the home screen, click general, scroll down to the reset button near the bottom of the list, and click reset all settings.

This will take a few moments, and the phone might shut off during this process. If it does, turn the phone back on and monitor the heat and the speed of the phone. If it continues to overheat, you can try any of these other methods.

Giving the phone a restart

Sometimes, you can fix an issue by turning the phone off and on again. A hard restart turns the phone off in the middle of the activity and forces it to close all of the apps and shut off.

Track apps causing issues

Some apps available in the app store do not mesh well with the hardware of an iPhone. This means you need to figure out which app does not agree and delete the app. If you know that one of the apps on your phone is causing an issue, but you don’t know which one, you can figure that out in settings.

Click on settings, click on the icon with a blue and white hand that says privacy, and then click on analytics. This will bring you to a screen that shows your analytics data. Click on that and find the app causing the phone to crash, restart, overheat, or all three. Delete the app and see if the overheating continues.

Restore your iPhone

Restoring your iPhone is a great way to stop your phone from overheating. To do this, you’ll need to plug your iPhone into a device that has your Apple ID information stored. A Macbook or a desktop works perfectly. Also, make sure you have your information stored in the cloud because restoring a phone will delete data from your iPhone.

• Open the finder app, the blue and white smiley face icon at the bottom of the computer.
• You need to push the volume buttons as well as the power buttons until the iPhone shuts off completely.
• Now hold the side button for a few moments, the high volume button with the side button, and the lower volume button with the power button for a few more moments.
• After you’ve completed all of those tasks, a pop-up will arise on your computer. It will ask you if you want to restore your device.
• Click Restore iPhone under iPhone Recovery Mode and wait until the restoration finalizes.
• After that process, give the iPhone a bit to recuperate and then try to charge it again.

Update apps and iPhone

If you find your iPhone overheating while charging, you can update the software and the apps.

If a phone has several old apps and older software, it could cause the device to overheat. You’ll need to see which apps need to be updated by visiting the app store.

Apple Store

If all else fails, you can always visit an Apple Store and speak with someone at the Genius Bar.

If you don’t notice your phone getting hot, but you think it might be overheating, there are some other methods to prove the software is heating up. These include,

• The software operates at a slower pace. You can’t access apps at a normal speed.
• If the phone does not charge at all or charges at a super slow pace.
• You try to take a picture, but the flash is unavailable.
• The screen doesn’t light up as much as usual or it is black.
• You get a temperature warning.

You already know that you can delete all your third-party contacts. As for how to do that, just follow these steps.

These steps will help you delete them, although you do need to stop syncing your contacts if you want to avoid having to do this in the future again.

1. Head over to your Settings app on your iOS device and choose your Contacts.
2. Tap your Accounts button. This will show you accounts like your Gmail. You only need to tap on the accounts that you want to delete the contacts from.
3. In your options menu, scroll down. You should see various toggles—turn off the one for your Contacts.
4. A popup will appear that lets you Delete from My iPhone. You only need to click it to delete all of those contacts from your account.

Your iPhone device has something called iCloud Contacts. This will let you manage and keep your contacts updated across all of your devices.

Unfortunately, this is also what can cause problems for you if you have syncing across everything and your contact book ends up being cluttered.

So, if you want to stop syncing, you can delete all your iCloud Contacts that have been previously synced.

1. Start by opening your Setting app on your iPhone. You should see your own profile. Click your profile and choose iCloud.
2. If you scroll down a little, there is an option there that says Contacts with a little toggle bar. You will want to click on that bar so that it is activated.
3. You should see a popup from the bottom that will ask you what you want to do with all your previously synced iCloud contacts.
4. Just tap the Delete from My iPhone/iPad.

While it is important to stop syncing contacts, how about deleting all the other contacts that you have on your iPhone?

If you just want to delete a few contacts on your iPhone, you can do that, but just remember that deleting them from your phone will also delete them from other devices where you are using iCloud.

1. Start by opening your Contacts.
2. Scroll through to find that contact that you want to get rid of. Click on it.
3. You should see an Edit at the top-right corner. Tap it.
4. Scroll down now to the bottom of the screen.
5. You should see a red bar that says Delete Contact.
6. Click that and you’re done—contact deleted.

This does mean that if you have multiple contacts that you want to delete, you have to repeat this process for each one. It can get a little tedious if you have a lot of people that you want to get rid of. This brings us to the next step of deleting multiple contacts.

Ordinarily, you cannot delete multiple contacts at once. For example, if you are using an iPhone, you have to go through your individual contacts one by one. But if you are using iCloud, you can indeed select multiple contacts to delete them with just one click.

The only thing you should keep in mind is that this is something you can only do on your computer. You cannot delete multiple contacts from your iPhone directly.

1. Begin by opening your web browser and go to icloud.com. If you haven’t visited icloud.com from your computer before, you will be asked to sign in with your Apple ID and password. This is the same sign-in that you might use to enter your iCloud from your phone. This might also require something like two-step verification from your phone as well.
2. Once you are signed in, you will see all your classic iPhone icons. You should see contacts as one of those icons. Click it and highlight each contact that you would like to delete.
3. You can do this by holding down the Control key and clicking all the contacts you no longer need. For those of you using a Mac, you will be holding onto the Command key instead as you tap your contacts.
4. Once you have all of those are highlighted, be careful not to click away or you will have to highlight them all over again.
5. Now, go to Settings at the bottom left corner. You will see the Delete button, and you only need to confirm that you would like to be rid of all the contacts.

Any devices that are linked with that iCloud account will now be rid of those contacts. But, of course, this means that any devices not connected will still need to be handled manually.

As mentioned above, you can go into your iCloud to delete multiple contacts, and this works if you have been syncing contacts. You can also just delete all your synced contacts too.

But what if you want to delete third-party contacts right from your iPhone. If you want to do that, you can use a third-party app to help you. These are known as smart contact managers, most of which cost just a little bit to download.

For example, you can try Groups, which is free. However, there is a more comprehensive version for about $10.

Delete Contacts+ is another third-party app that also comes with a free option or a full version priced at $4. Look into each of them to figure out if the extra cost might be worth it to you. No matter which one you pick, both are easy to use and work reliably to remove multiple contacts in your iPhone.

In terms of how to use them to get rid of your contacts, let’s focus on Groups. Bear in mind that the actual process should be relatively similar no matter which app you choose. Launch your Groups app and let it access your contacts. You should see a button that says All Contacts.

From here, you can wipe out every single contact from your iPhone if you Select All at the top left of the screen.

If you would prefer to just select contacts, you can click to select the ones you do not need anymore.

You should see a button that says Choose Action right at the top. It will give you the option to Delete Contacts in the popup menu. You only need to confirm what you want to do.

If you want, you can verify that these contacts are gone right from the Contacts app, but you can also check on your other listed devices to be sure they’re gone.

How Many Contacts Can I Have?

You really should never exceed your contact limit since you can actually have around 50,000 contacts. Hopefully, you never actually have quite that many. But if you do, you know how to delete them now.

How Do I Sync Contacts?

You can also sync contacts if you want them to be the same across all devices. Just go to Settings, tap your name, and pick iCloud. Then, scroll through your list to move the slider and allow your contacts to sync.

Can I Organize My Contacts?

Yes, your iPhone does give you some customization options that will let you control your contacts list better. If you get anywhere close to that maximum of 50,000 contacts, or even just have a couple hundred, you might want to see whether you can do this.

To find the variety of controls, go to your Settings and then your Contacts. You can sort by first and last name like this.

Or you can organize your contacts by genre. For example, if you have personal contacts and work contacts. Now, this might not be the easiest thing to do if you have not input things like work emails and personal emails with your contacts, but you can still manually choose which group to.

Can I Just Delete All Contacts?

You cannot pick and choose which contacts you want to delete, but you also cannot choose to just delete all contacts and start over. You will need a third-party app or will need to go to your iCloud to pick everything at once.

What About Contacts Stored on My Phone?

There are some contacts that are stored directly on your phone and not on the Cloud, which you can still delete. These are the contacts that you need to delete one by one, though. Or you can do a factory reset if you genuinely want to completely start over.

These are all effective methods to delete contacts on your iPhone. If you have been bothered by all the contacts cluttering your iPhone, there is no need to bear with it any longer. Simply follow these methods to clear the contacts you no longer want and enjoy a more organized iPhone!
