I plug my iPhone in every night right next to my bed so that it can charge. My goal is, of course, to have it at 100% when I wake up in the morning. But this morning it was only at 4%, which was very strange because it was plugged in as normal.
Then I took it to another computer, with my iPhone USB cable, to plug it in. At this point it was now at 4% charged. When I plugged it in, the charge icon lit up (like it was charging) but then would immediately disappear.
I unplugged it and then plugged it in several times and the same thing happened – the charge lit up, then immediately disappeared.
So I had a problem – my iPhone won’t charge.
Here’s how I fixed the my iPhone won’t charge problem:
All I did to fix this problem was do a hard re-boot of my iPhone:
1) Hold down the power button (at the top of your iPhone) and the home button (the circle button on the bottom of your iPhone) at the same time.
2) Hold both buttons down at the same time until your see your iPhone reboot. You’ll now your iPhone rebooted when you see your screen flicker off.
3) Now just push the power button only at the top of your iPhone until your iPhone turns on.
Now go ahead and plug your iPhone back in using your iPhone USB charger.
My iPhone then started to charge as normal.
Let me know if this worked, or didn’t work, for you!
