After 30 seconds, press and hold the power button until the Apple logo appears, then release.

Why is my iPhone not detecting my headphones?

1. Headset is connected to the iPhone and it says that "this accessory is not supported by this device".

Please refer to the following operations:

It may not be the original earphone, the earphone and the phone hole are not compatible, causing earphones not working even it can charger. Since the iPhone 7 needs to use a 3.5 mm headphone product with an adapter, it is very likely that there will be compatibility problems between the headset and the adapter. Second, make sure you have the latest version of iOS.

2. It may be that the headset has failed. You can try another headset or charging and headphone adapter for iPhone. If this problem occurs with another headset, you should ask the Apple Store for help. If the other headphones are working properly, it means you need to replace the new one.

3. After plugging in the headset,open the Control Centre and check to see if the phone volume is off and turn it on.

If you plug the earphones into the iPhone and can't hear any audio, it's possible that the volume on the iPhone has been turned down to a minimum.

Increase the volume on your iPhone.


Press the up-volume button on the left side of the iPhone to turn up the volume. When finished, a small box will pop up in the centre of the iPhone display to indicate the volume of the iPhone.

When the Sound box appears, check two things:

Make sure the "Headphones" are displayed on the top of the box. This confirms that your headset jack has detected that the headset is plugged in.

Make sure there is a volume bar at the bottom of the box. If Mute is displayed, the audio will not play through the headphones.

If the box does not appear when you click the volume button, open the "Settings" and "Sounds& Haptics". Then, turn on the switch next to "change with buttons."


4. Clean an iPhone's charging port and Confirm if there is any damage

Remove any debris from the charging port on the bottom of the iPhone and make sure nothing covers the headset. You can try to remove any stuck lint, linen or other debris from the headphone jack, which may cause iPhone headphones not detected. You can use an antistatic brush to clean the headphone jack.

5. Check audio IC board

It takes a long time to start the phone.

In the voice memo application on the phone, you cannot record a voice memo and say that no playback device is available, etc.

If you have both of these symptoms, it may be due to the audio IC problem caused by the phone bending,this is a repairable fault, but it needs to be soldered.

If the phone does not have the above two conditions, please try to clean the charging port, please make sure that the earphone or adapter in the port is clean and leave a small gap of about 1 mm.

6. Disable Bluetooth on iPhone 8

To ensure that audio does not play through other devices such as Bluetooth speakers or headphones, turn off Bluetooth on iPhone 8. iPhone audio may have reached other Bluetooth devices and your headphones can't receive sound. So, you think the headphone is not working on iPhone.


Swipe up from the bottom of the screen to open the Control Centre.

Then, press and hold the audio box in the upper right corner of the Control Centre.

Click the AirPlay icon.

Make sure a check mark is displayed next to the headset. If the check mark is displayed next to other devices, tap the headset to switch to and select the headset for the sound output.

Or you can just turn off Bluetooth or forget the Bluetooth device on your iPhone. Doing so removes all saved Bluetooth devices from the iPhone and disconnects the Bluetooth devices.

7. Reset all settings on iPhone 8

Open the settings from the home screen.

Click General.

Scroll to and click Reset.

Select the option to reset all settings. This will reset the system settings and restore the default settings without affecting your iPhone data.

If prompted, enter your device password.

Then click on the option to confirm the settings reset.

Howto fix a phone with a spot screen?

The screen of a mobile phone usually contains two main parts, the LCD screen and glass.

The glass covers the LCD to prevent accidental damage and occasionally acts as a digitizer on touch-screen phones. Although the glass is easy to replace on many models of mobile phones,if the LCD of the mobile phone breaks, it is almost necessary to completely disassemble the phone when replacing it.

1. Remove the battery cover,battery and all cards from the device, such as a SIM card or SD card.

2. If your phone is a clamshell device, remove it from the screws on the back of the device and the screws around the LCD. The type of screw will depend on the manufacturer and model of the phone, but is usually a T4, T6 or #00 Phillips screw.

3. Use a pry bar to pry the case out of the device. Once it is determined that all of the screws have been unscrewed, simply insert the crowbar into any position between the two outer casings and then move the crowbar around the outer casing to pry the clip between the outer casing and the main body. Continue to remove the housing until only the control board and LCD are left and half of their respective housings.


4. Disconnect the control board from the LCD and digitizer if necessary. On most devices, you'll find cables from the LCD to the control board. Lift the connector to disconnect the cable.If you have a touch screen device, you must perform the same task on the cable from the glass to the control board.

5. Pick up the LCD to remove it from the case. On some devices, you must also smash the glass away from the LCD. In these cases, using a heat gun on the glass for about 30 seconds loosens the adhesive enough to separate the glass. Note that some devices, such as the iPhone, permanently hold the glass and LCD together. When you get a spare LCD,check to see if it contains glass. If so, you can skip the part to split the glass and LCD apart.

6. Place the broken LCD aside and install the spare LCD screen in the housing. Simply reassemble the device by simply reversing the steps to disassemble.

The Bottom Line:

If the black spot on phone screen spreading, you can replace the phone screen assembly separately. Since the replacement of the external screen requires a series of operations such as dismantling, separating, removing glue, and installation. In general, change screen by yourself is the most cost-effective way. But for many people, it may be a more difficult operation. You can also go to the Apple store for repairs.

How to clean iPhone files:

Open Settings

Point General

What Risk of Replacing iPhone Battery

I ve had this iphone 6s for almost 3yrs now. Battery life is n't THAT bad that i need a new phone but i was wondering if i would have longer battery life if i replace it with a new battery? Or would there be a risk of getting my phone bricked if i do that?

What to do before replacing iPhone battery?

What should I pay attention to?


The effect of replace the iPhone battery by yourself:

1. Warranty

After replacing the non-certified battery, you will lose the warranty service provided by Apple. Because Apple has instructions in the maintenance policy, if it is disassembled through unofficial channels, or disassembled, it will refuse to provide warranty services. This means that if we replace the third-party battery, we will no longer be able to replace the original battery with Apple.

2. Disassembly iPhone part

When replacing the battery, yourself, remove the cable before removing the battery. If the pull-on glue is accidentally torn, the glue can be deactivated by slightly heating the air cylinder. You should find professional mobile phone maintenance staff, otherwise it may cause improper installation, battery overheating or explosion.

3. IOS battery health

The battery that is not verified by Apple cannot check the battery status through the IOS battery health function, and the maximum capacity and peak performance capacity indicators are not recorded. Battery health was introduced of iPhone,which delayed battery aging. Users can check the health of the battery, whether it is running unhealthy, and whether it needs to be replaced.

To buy an iPhone battery, we need to notice:

Do not buy or use unsecured battery products. There are many battery products on the market, and some low-cost batteries cannot guarantee the quality, which may affect the mobile phone or even burn out the phone.

Don't try to replace the battery yourself. It is best to find professional technician to install and replace the battery.

Because Apple used a large amount of double-sided tape to fix the battery and the fuselage inside the case when making the iPhone, so when replacing the battery,it is often necessary to use a professional heat gun to heat the body, to smooth the battery. Take it out from the inside of the body. Although this process seems simple, it still requires some skill.

If you use a force or a sharp tool to force the battery out, it may pierce the battery's outer casing, causing a short circuit inside the battery, or even causing spontaneous combustion or explosion.

If it is to replace the third-party battery of the regular brand, it will not cause any malfunction to the mobile phone. Regular manufacturers' batteries are rigorously tested at the factory. Due to the different manufacturing processes of various battery manufacturers, the battery capacity will be different from the original battery, which is normal.

Suggestions for replacing your iPhone battery yourself:

1. The repair budget is enough, if you want to get official protection, select Apple's official channel to replace the battery.

2. Experienced disassemble personnel, it is recommended to buy a third-party certified battery replacement.

3. Will I lose data if I replace iPhone battery? Back up the photos and data files in the iPhone before replacing the battery to prevent the phone from being damaged due to the disassembly process.

Where can I buy an iPhone replacement battery:

Apple does not sell OEM (Original Equipment Manufacturer) parts to the public, which means you need to purchase a replacement iPhone battery from a third-party manufacturer through a retailer. GEMWON can provide you with bulk price mobile phone repair accessories, such as iPhone screen assembly, charging port, camera, iPhone battery and soon. You only need to place an order online and you will receive the iPhone parts you need within 10 days.

Replace the iPhone battery:

Remove the external screw,

Disconnect part cable,

Remove the old battery from the housing,

Reassemble iPhone with new battery,

For experienced disassemblers, it can be completed in as little as 20 minutes. Even an inexperienced average iPhone user should be able to complete it in an hour.


For how to replace the iPhone battery, I suggest you refer to our previous article Howto Replace iPhone X Battery Yourself. In recent years, the internal battery of the iPhone replacement steps is similar, no matter which generation of iPhone you have, this tutorial can help you.


It is more secure to replace the battery after Apple store, but expensive is the most obvious shortcoming. I believe that more people will choose the best buy iPhone battery replacement online and replace it, which will save you more maintenance costs. Especially if your iPhone is not in warranty, you will have fewer concerns.
