Fix 1: Turn off Optimised Charging

Many of us iPhone users tend to turn on the optimized sharing feature on our iPhones so that our iPhones get used to our usage pattern and then charge according to the same. Although this is one of the best features of the iPhone to save battery life, it charges the iPhone 50 to 80% when we sleep and then charge the rest in the last 1-2 hour of our sleep.

  5. When a popup appears, click on the button that says only “Turn off.”

Fix 2: Check Your Battery Health

Battery health is also a great feature of Apple devices that shows you the current state of your battery and possible fixes. However, a bad battery or a battery with very bad health can neither charge properly nor stay charged for longer. Apple has decided on a threshold of 80% for all its batteries. Any percentage above 80 is good, and the lesser is bad. If your battery health is lower than 80%, you should immediately get it changed with your nearest Apple service center. But first, check your battery health in these easy steps:

One of the main reasons for your iPhone not to charge is overheating. This is not just an iPhone issue. Battery overheating is an issue with many devices, including laptops with batteries. The worst part is that heated batteries can even lead to the explosion of any device. To overcome the heating issues, you can follow the steps given below:

  1. Do not use your phone while charging.
  2. Do not expose the phone to direct sunlight.
  3. Do not use your phone beside a fire.
  4. Do not overclock your device.

Fix 4: Check Your Lightning Cable

There can be times when you might get a bad lightning cable or your lightning cable might get decayed in the long run. Using a bad lightning cable can make the situation worse. If you use a bad lightning cable, there might be chances where you might face issues that you have never expected. A shorted lightning cable can burn your mainboard too. To fix these issues, follow the steps:

  1. Visually check for any defects on the lightning cable.
  2. Try to use it on any other device and check if the issue persists.
  3. Try using a different lightning cable and check for any issues.

After you are done with the troubleshooting and find out that your lightning cable has some issues, buy an original one as soon as possible to avoid any consequences with your iPhone. However, if you think your lightning cable is alright, you might have the last problem we will discuss now.

Here are some of the troubleshooting that you can do to check the situation of your lightning port:

  1. Check for any debris in the port. If there is any, try to clean it with some cleaning solutions and a toothpick.
  2. If cleaning debris does not work, check if any connection is broken in the lightning connector.
  3. If that also does not work, there might be a chance that the connection is broken from the inside.
