Hi, I'm really frustrated by this! I have an iphone 6s and a 2015 macbook pro. If I try to charge my iphone from the macbook, it keeps cycling between charging and not charging - like every 2 seconds! What could be happening? these are both apple products and they can't seem to work together - very frustrating! thanks for any help!
MacBook Pro with Retina display, macOS High Sierra (10.13.2)
It's probably a short within the connection cord itself. Have you tried connecting it to another port? Try using a different cable (if you have one).
Computer
Plug your charging cable into a USB 2.0 or 3.0 port on a computer that's on and not in sleep mode. Don’t use the USB ports on your keyboard.
Follow these steps and try again after each:
- Check your charging cable and USB adapter for signs of damage, like breakage or bent prongs.* Don't use damaged accessories.
- Use a wall power outlet and check for firm connections between your charging cable, USB wall adapter, and wall outlet, or try a different outlet.
- Remove any debris from the charging port on the bottom of your device, then firmly plug your charging cable into your device. If the charging port is damaged, your device probably needs service.
- Let your device charge for a half hour (If your device is unresponsive afterward, learn what to do).
- Force restart your device:
- On an iPhone X, iPhone 8, or iPhone 8 Plus: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Then, press and hold the Side button until you see the Apple logo.
- On an iPhone 7 or iPhone 7 Plus: Press and hold both the Side and Volume Down buttons for at least 10 seconds, until you see the Apple logo.
- On an iPhone 6s and earlier, iPad, or iPod touch: Press and hold both the Home and Top (or Side) buttons for at least 10 seconds, until you see the Apple logo.
- Let your device charge for another half hour.
- If your device still won’t power on or charge, take your device, charging cable, and charging adapter to an Apple Retail Store or Apple Authorized Service Provider for evaluation. You can also contact Apple Support.
Also, keep in mind that the USB ports on your Mac aren't intended to be used to charge phones. That's why the iPhones come with their own higher output (5 watt) power supplies.
I didn’t say that it couldn’t be done. You Mac’s USB ports put out 2.5 Watts, your iPhone charger is 5 Watts. You be the judge.
Sorry but that makes no sense. Directly from Apple that you can charge your iphone from your computer - https://support.apple.com/en-us/HT201569
Thanks. I tried the restart and not sure how to clean it (the iphone charges fine from car and wall outlet) so I doubt it's a cleaning problem. I need to take it into the apple store.
