Sometimes, the phone battery shows a lightning symbol when plugged in but the percentage does not increase. Your iPhone turns ON when plugged in but it does not store charge. When you disconnect the charger, the phone turns off. It means the battery, charging port, or power management IC chip is defective. There are many reasons behind this issue. Let us consider each problem and its solution.
1. A Problem in the Charging Port
Clean the charging port of your iPhone. It may have accumulated debris or dust. So, the charger cannot connect properly. Use a toothpick, tweezers, or bobby pin to clean the charging port. Be gentle while cleaning the port.
2. Emptied Battery
Another reason is that the battery has gone dead. So, it takes more time to start up and charge the iPhone. Keep the charger connected at least for 30 minutes. Do not perform any function during this time.
Now, check the battery again whether its percentage is increasing or not. If it is working, the home screen will appear. Charge your iPhone fully. Then unplug the charger. If the phone again turns off then you must seek a technical assistant.
3. Defective Button
Check the sleep/wake button on your iPhone. Maybe it is not functioning. You can identify a non-functional button. Sometimes, the button is very loose and pushed inside. When you press the button, it does not respond. In this case, you should take your iPhone to a service center.
4. Check LCI
The iPhone has a visible Liquid Contact Indicator (LCI). It tells you if water has damaged your iPhone. This is located at the right, left, or bottom of different iPhone models. Use a magnifying glass and project light on LCI to check its status.
Normally, the LCI is silver or white but when it comes in contact with water, it turns red. So, if you see the LCI indicator red then your iPhone has been damaged by water. This causes the problem of charging.
5. Restart your iPhone
There may be some software issue. So, your iPhone slows down and creates problems in charging. Restarting solves many issues. Let us understand how you can restart different models of the iPhone.
