Why isn’t my phone charging? Find out why and how to fix it.

The cell phone doesn’t charge or does it take a long time to complete the recharge? A damaged cable, dirt in the device input or even the outdated system can be the reasons for the problem. Check out why this happens and what to do to resolve the situation.

1. Restart the device

It seems a bit obvious, but by restarting the smartphone it’s possible to rule out any temporary issues that might be happening. The action terminates all processes that run in the background, updates components, and clears the cache.

  • Android: in general, just press the phone’s on/off button for between 5 and 7 seconds. Or, press it once and tap on the reset option that will appear on the screen.

On iPhone: The process varies by model:

  • iPhone X or 11: Press the volume and side buttons.
  • iPhone 8, 7 or 6: just keep the side button pressed.
  • iPhone SE, 5 or earlier: press the volume and top buttons.

If your device charges up again normally, we suggest you check out recently installed apps. It’s possible that one of them is running in the background without your knowing it. In addition, it is likely consuming the battery faster than the device can recharge.

2. Check cable, charger and adapter

Problems with the charger, cable or adapter can be the cause of the cell phone taking too long or not even charging. The cable may have some loose wires or the adapter may be having difficulty transmitting current effectively.

If your smartphone only charges when it’s connected to a USB port, the problem may be with the power adapter. If it still doesn’t work, try a new cable.

There is still a possibility that the socket or USB port is having problems. Therefore, it is also worth trying to charge the device on another source of electrical energy.

If you decide to replace any component, the ideal is to use an original replacement of the brand of the device or a third party recognized by the manufacturer. It is also worth remembering that charging through the socket is much faster than through USB.

3. Clean the loading door

By following their owners all day, cell phones tend to be exposed to all sorts of dirt. This debris can settle on the charging port and interfere with the device’s connection to the power source.

Grab a flashlight and light the entrance to check for possible debris. With the cell phone turned off, blow out the door or use a can of compressed air to clean it.

The use of tools is not recommended by the websites of manufacturers such as Samsung. The company explains that inserting any object into the loading door could damage the entrance.

4. Use a wizard app

This tip is only valid for Android users. the app Ampere informs how much electrical current is consumed while charging the device. It also indicates consumption while the cell phone is not connected to a power source.

The feature is ideal for when the smartphone does not indicate that charging is taking place. In these cases, what might be happening is a software error, which can be resolved by restarting the device or updating the operating system.

If there is current, the app can be used to find the most effective source to recharge.

5. Check the temperature

It is common for cell phones to heat up while they are being charged. But, if the temperature rise is beyond what is considered normal, it is possible that the charging will be interrupted.

According to Apple, this is done to increase battery life. On the company’s smartphones, if this happens, the software stops charging above 80%. It will only be resumed when the device’s temperature returns to normal.

On iPhones, the system itself issues a message warning about overheating. On Android, it is possible to check the temperature of the device also using the Ampere app, indicated above.

6. Charge with the cell phone turned off

For those who can’t leave their cell phone alone even while it’s charging, it might be a good idea to keep it turned off during the process. Checking Instagram, playing games and exchanging messages can extend your recharge time.

The on screen consumes a lot of power from the device. Especially when the user taps on it constantly, such as when accessing social networks, playing games or chatting.

7. Update the operating system

An error in the software that recognizes the charging cable can be responsible for problems in charging the phone. Therefore, if there is any operating system update available, it is recommended that you do so.

In addition to news, updates often bring corrections for possible errors.

  • Android: Configure → System → Advanced → System Update → Check for Updates.

8. Restore factory settings

Resetting your smartphone allows you to reset the device by resetting to factory settings. This means that all data, apps and settings included after purchase will be deleted from the device.

Therefore, if the problem is occurring due to some installed software, it should be resolved. Before proceeding with the process, it is highly recommended to back up your data and files. Otherwise you will lose everything.
