What is flashing lightning bolt iPhone?

Answered by Jeremy Urbaniak

The flashing lightning bolt on an iPhone usually indicates that the device is charging. When you connect your iPhone to a power source, such as a wall outlet or a computer, you will typically see a battery icon on the screen with a lightning bolt symbol next to it. This indicates that the device is actively charging.

The flashing of the lightning bolt symbol is a visual cue to let you know that the charging process is ongoing. It is a normal behavior and is designed to inform you that your iPhone is successfully connected to a power source and is receiving power.

However, there are instances where the flashing lightning bolt on your iPhone may not be a normal charging indicator. If your iPhone screen is flashing while charging, it could indicate a hardware issue with your device.

One possible cause could be that the wall outlet you are using is not delivering enough power to charge your iPhone properly. In such cases, try using a different wall outlet or charging adapter to see if the issue persists. It’s also worth checking if the charging cable you are using is damaged or faulty. Sometimes, a damaged cable can cause intermittent charging issues, leading to a flashing screen.

Another potential cause could be debris or lint that has accumulated in your iPhone’s charging port. Over time, small particles can get stuck in the port, preventing a secure connection between the charging cable and the device. This can result in intermittent charging and cause the screen to flash. To resolve this issue, you can try gently cleaning the charging port with a soft brush or compressed air. Be careful not to damage the port while cleaning it.

If the problem persists even after trying different power sources, cables, and cleaning the charging port, it is advisable to contact Apple Support or visit an authorized service center. They can further diagnose the issue and provide a solution.

While the flashing lightning bolt on an iPhone screen is usually a normal charging indicator, if it occurs intermittently or persists despite using different power sources and cables, it could indicate a hardware issue. It’s important to troubleshoot the problem by trying different charging methods and cleaning the charging port before seeking professional assistance.
