Why iPhone Not Charging But Turns On When Plugged In?

1- Faulty Adapter

Apple 5W Adapter

iPhone 11 or older series comes with a 5W power adapter. After using it for many years, the current output capacity decreases and doesn’t provide sufficient current to charge your iPhone.

2- Broken Lightning Cable

Faulty Lightning Cable

Due to continuous plugging and unplugging of charging, the lightning connector gets damaged and won’t pass current at its full capacity.

Because of low current output, your battery won’t charge, but the display turns when connected.

3- Overheating

iPhone Temperature Warning

Heat is the biggest enemy of Li-Ion batteries, and the iPhone has an inbuilt safety feature to cut off charging activity if battery temperature increases to a certain level.

If your iPhone is overheating, it won’t charge when you plug in the lightning cable.

4- Dirty Charging Port

Dirty iPhone Lightning Port

The lightning port attracts dust and debris from our jeans pocket, couch, or environment. A layer of dust blocks the charging pins and prevents the current flow.

If your lightning port is dirty or clogged with debris, it won’t charge when plugged in.

You need to unclog and clean the charging port with a cotton swab and rubbing alcohol.

5- Degraded Battery Health

iPhone Low Battery Health

Apple battery health decreases to 80% of its full capacity after 500 charge cycles. However, it also depends on your charging pattern and usage.

If your iPhone is more than three years old, then there is a chance that its battery health is degraded.

In this case, your iPhone display will turn on because of current input via the charger, but the battery won’t charge.

6- Buggy Software

iOS Update

Buggy software is another common reason why your iPhone faces charging problems.

It usually happens when you’re using an older-generation iPhone. However, Apple frequently releases iOS updates to fix the reported bugs.
