Your iPhone won't charge wirelessly when connected to USB. If your
iPhone is connected to your computer with USB, or if it's connected to
a USB power adapter, your iPhone will charge using the USB connection.

I'm going to go out on a limb here and say that imho, anything claiming to be designed in "Califomia" is not a genuine Apple product :3
Apple's official article -- Identify counterfeit or uncertified Lightning connector accessories -- may help you confirm my suspicions.
For those not liking hidden links the full address of the Apple article above is https:/...
There is a lot of misinformation in some answers. I will give the facts.
No MagSafe adapter, when plugged into a mechanically matching receptacle on a MacBook/MacBook Pro, will cause an unsafe condition. This is a given for the systems to receive safety certifications. So no, a 60W adapter won't overheat when connected to a machine that needs an 85W adapter....
Running this in terminal worked for me: (it will ask for your user's password)
sudo killall -STOP -c usbd
This pauses the troublesome process instead of killing it altogether like other answers suggest. The difference is that macOS won't try to reopen it automatically and cause the issue again.
Running sudo killall -CONT usbd will resume the process, ...
This cable costs $39 retail. At this price I am expecting better
performance for charging than what I'm getting here. How could I
diagnose this issue?
There's nothing to diagnose because everything is operating as it should.
The problem is not the cable (it's irrelevant, actually) nor the iMac as it's only capable of delivering up to 15W of power via ...
Once I force-quit the process "usbd" this problem went away.
Open Activity Monitor -> View -> All Processes -> Search for usbd -> Double click -> Quit -> Force Quit
Here are a couple of manual pages on the usbd process, for more information:
This answer is indented to be canonical answer for similar questions and applies to all devices that utilize USB Type C chargers and conform to the USB 3.1 specification.
If there is only the Macbook 12 inch USB-C charger nearby, can it be used to charge other USB-C devices, such as any Android phones that also use USB-C? (will it "too powerful" and ...
Apple recommends to plug the adapter into the wall before connecting it to the computer.
For more information, refer to the Apple Support article, Using and maintaining your Apple MagSafe Adapter.
Connecting the MagSafe Power Adapter to power
Make sure that the AC plug or AC power cord is fully inserted into the power adapter before plugging the ...
Sounds like you got a sticking ground pin.
Just plug it out when connecting to the laptop horizontally (with more force) and stick it back it horizontally as well. Usually this is due to you removing the plug by lifting it (feels gentle but actually bad) rather than yanking it.
Apple's guide is quite long and a detailed picture of the lightning connector should show the quality regardless of the color or font.
That being said, the fonts here show this as a fake. Notice the similarity between the rn in California and m in assembled. I'd have to see it in person but unless this is a really distorted picture, they are appear too ...
Yes, but only with the iPad in sleep mode.
The iPad requires at least 500mA from a USB port:
Apple peripheral devices may request more than 500 mA (Milliamps) at 5 V (Volts) from a port to function or to allow for faster charging. Such Apple peripheral devices include:
Alluminum Wired Keyboard*
About wired keyboard we get the ...
Yes, you can use your iPhone charger with the iPad.
This should not damage the iPad or the charger.
However, since the iPad is provided with a lower current the charging takes longer. Both the iPhone and iPad charge with 5V, but the iPad charger provides 2A while the iPhone charger only provides 1A.
This is why it takes longer to charge. You should ...
Battery level indications are notoriously unreliable in most devices. That's why it's known as the indicator rather than the gauge, as the latter implies accuracy (same goes for car fuel tanks, which is why when there is less than approximately 30 miles of fuel left, my car then stops telling me the level and just says "Refuel!!"). It's very common to note ...
The USB-C plug is not the problem, but the charger is.
It is underrated, so it will never manage to completely charge your battery while the Mac is in use, or supply enough when needed.
With that said, you can use it to charge battery overnight to use it during the day.
To verify it is best to take occasional look at the battery charge condition in ...
More amps will not mean faster charging. The iPhone (and any electronic device) will only take as much current as it requires, and no more. The iPhone will take 1A to charge, and an iPad will take 2.1A.
There's no harm in using a charger that is capable of providing more current than a device requires, but there's no benefit either.
Providing less current ...
I found the answer to my charging problem in another question:
Please make sure to upvote the answer I linked.
Short version: yank the cord forcefully and horizontally out of the notebook. Repeat it a couple of times, until the orange light starts and it starts charging. Visit the link for more information.
I'd guess genuine:
No Apple logo: none of my (genuine, coming with an iPhone or iPad) cables have the logo.
Cardboard holder: Apple do use cardboard holders for those cables, including the one in your photo.
I don't see what's odd on the guide books, I have the same as the one on the left on your photo (except mine don't have staple) that came with an old ...
According to Apple's support document on the subject:
For the quickest charge, connect the device to a power outlet using the USB cable that came with the device and an Apple USB power adapter.
The USB spec limits the amount of current that a device may draw from a USB port (500 mA); the included Apple standalone power adapter can supply double that (1 A)...
Yes, you can use the simple adapter. If you read the tiny fine print on the plug end you see "110-240V 50-60Hz" which means it will work on most common electrical systems around the world without a transformer.
You can use either port, the limitation is that only one USB port can provide this higher power level. If you try and charge two iPads at the same time, only one will get provided with the higher power level, and the decision as to which is made on a first-come-first-served basis.
Edit to Add: I forgot to mention that the article says Macs with more than ...
The problem is the electrostatic current/charge/grounding while using Charger.
First make sure you do use the original Charger.
If your iPhone is in a leather case, remove it.
If you have a protective case, or if you are using a plastic sheet or film on the display, try removing them and testing the device without it.
I missed the point of you ...
Unless there is some reason to the contrary that I'm not aware of, yes, you can use your MacBook charger with your iPhone. The power adapter will only convert as much power as is drawn, and the iPhone will only draw as much power as it needs.
(Note that it is not a good idea to charge your MacBook with an iPhone or iPad charger!)
Yes you can. I finally figured out how.
Use a dongle and hook them up like this:
power supply > usb-c cable > mbp > usb-c cable > usb-c multi-port dongle > mbp2
I've tested it with the UpTab displayport with power delivery adapter and with the Apple multiport adapter (A1621).
In my experience, 15w is enough to power and charge the 15" mbp....
Fake. Aside from the other things people have noted (rn/m substitution, wrong serial number format, shoddy paperwork, etc), the font on the cable is a dead giveaway. Apple's standard corporate font has been Myriad since 2002. The fake cable is using Arial.
The typesetting of the serial number is also wrong. The genuine cable moves to a smaller font with ...
I am not sure about MacBook Air, but in my MacBook Pro (Mid 2010) it will charge my iPhone if the MB is active (powered up and not sleeping) and it will also charge my iPhone when sleeping, but only if the iPhone was plugged in before the MB went to sleep.
If your MB is shut down (not active & not sleeping) it will not charge your iPhone.
Like you said in a comment, it's more a software limitation. Even though there's probably some hardware safeguard.
If you plug your iPhone a millisecond before it reaches the shutdown limit, then, no harm done, it doesn't need to shut down, power is there to keep the phone running and recharge the battery.
If you plug you phone after the shutdown limit, ...
Charging more slowly won't make any difference, other than reducing the slight side effect of heat buildup on the iPad.
But it's perfectly OK to use lower powered ports such as those on your computer instead of the main powered chargers.
It's also perfectly OK to do it the other way around; you can charge your iPhone using the more powerful 20W iPad main ...
All Apple products have a charging demand circuit that senses the battery charge level and only engages charging current when the battery needs a charge.
When you plug in power to the iPad, it only initially channels enough current to run the system (or boot it up if it's off) and establish some sensing of the battery. At that point, it will start charging (...
Apple partnered with LG to create a 4K monitor that outputs 60W via USB-C. Apple has mentioned full compatibility with a 13" MacBook Pro (comes with 61W power adapter) but mentioned that with a 15" MacBook Pro, the battery will get drawn during intensive power usage and therefore it should be connected to its 87W power adapter. No mention of any dangers in ...
