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. Source: How to wirelessly charge your iPhone 8 or later.

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 ...

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 ...

According to Apple the best way to charge your MacBook Pro is with the included AC adapter. They don't mention plugging into an iMac specifically, but based on your report of a long predicted charging time, I'm going to guess that iMacs don't put out as much energy over thunderbolt as the AC adapter. According to this page on the Thunderbolt 3 Cable, it is ...

This always (eventually) happens if you use a Lithium battery long enough (and assuming nothing else breaks first). It also happens prematurely and would be covered by AppleCare / Warranty even if you do everything right in less common circumstances. To counteract this use newer hardware on iOS 11.3 or higher which have charge management features to ...

What you are observing is due to a security related change made in iOS 11.4.1. Using USB accessories with iOS 11.4.1 and later Starting with iOS 11.4.1, if you use USB accessories with your iPhone, iPad, or iPod touch, or if you connect your device to a Mac or PC, you might need to unlock your device for it to recognize and use the accessory. Your ...

There’s no on-screen indication of the charging speed on current iOS versions. The only way to really know is to time the charging, or use external hardware for USB-PD debugging that can show you the actual watts.

I have installed coconutbattery app for macOS. It gives this information and more for all the Apple devices that you connect (by cable, or WiFi for Pro version) on your Mac, both about battery, OS and charger. After installing the app, connect your iPad/iPhone, launch the app, click on the iOS Device tab and look for value corresponding to Cycle Count. ...

Make sure you're using the latest version of iOS. iOS 11.3 and later on the iPad introduces a feature to preserve battery health for devices which are constantly plugged in, which is exactly your situation: About iPad and iPhone Charge Management Feature ...when iPad or iPhone is connected to power for prolonged periods of time, such as when it is used ...

No, it's not possible to do that. The adapter you have pictured is the Nonda USB-C to USB-A adapter. It is commonly used for connecting older USB-A hardware (such as USB pen drives) to newer USB-C computers. One of the big differences between USB-A and USB-C is that USB-A does not allow for transferring enough power to charge a laptop (i.e. it is limited to ...

Imagine a water reservoir (battery) with water gushing out of a sluice (CPU usage), and a bucket (low-rated charger). You're putting water into the reservoir with the bucket, but it may not be equal to the rate of water coming out of the sluice. The reservoir level will fall, but at a slower rate than if you weren't filling it with the bucket. The Apple-...

I would start by resetting the System Management Controller (SMC) which is responsible for power management and controlling the thermal environment of your Mac. Typically this covers things like interpreting and responding to various sensors, battery charging, sleep/wake/hibernation, the power button and restarts/shutdowns, LED indicators, and so on. To ...

No it doesn’t. The new hardware and iOS can handle kiosk mode / constantly charged batteries much better than the old controllers so you should just keep it charged if you like that. Your XR can be kept 100% topped off without any long term harm. I disagree with Mac World and only think you should shut down the phone if you don’t regularly do that from ...

This questions risks inviting a lot of opinion, which also explains why it seems you can't find an article that can gives you a straight answer. However, to try and keep this to the facts, I refer you firstly to what Apple has to say about their batteries. You should also read this. In a nutshell, the key indisputable points are: Charge your iPhone ...

Newer iOS and hardware have a way to relax the security and allow charging / negotiation of fast charge even while locked. I'll let the OP answer cover that detail and keep the older details here. https://apple.stackexchange.com/a/351469/5472 The iPhone will charge at lower rates from a pure charging port, so you just want to put a data blocker on the USB ...

However, seems that the provided 5 W charger is not able to do that [charge the battery to 50% in 30 minutes]. I've been in the Apple Store and they said I need an iPad charger, but which one? You need a charger that outputs at least 18 watts or is rated for 5V at 3.6A (W = V * A) However, (IMO) you should get a charger that's capable of powering/...

Apple publishes technical specifications for its products and are available at its website. Have a look at: MacBook Air (13-inch, 2017) - Technical Specifications Under Battery and Power2 it shows: 45W MagSafe 2 Power Adapter with cable management; MagSafe 2 power port As your power bank only has an output of 5V/2.4A, which would be 12 watts, it's little ...

Apparently Apple disables drawing functionality while Apple Pencil is charging for performance reasons. So, the behavior is by design. Cannot use Apple Pencil while charging No, we disable the drawing functionality while it is charging (performance reasons). Although you can charge with a Lightning cable, it will charge much faster when connected ...

In my professional experience I say it was definitely the cats.

There actually is a way to find out when your iPad was disconnected from the charging cable. If you have iOS 12, you can go to Settings -> Battery and look at the graph. The part with the light green shadow with the little lightning symbol is the time when it is charging. When it gets unplugged, the light green section will stop and you can tell when ...

Just an important pointer for anyone considering to charge their switch with non nintendo chargers!! Watch out, using the non-nintendo certified chargers have a real chance of completely bricking your device. The switch charging standard is not completely the same and using a different charger could render your switch useless. More information: https://...

I replaced mine (MBP 2009) as soon as possible in the knowledge that Apple only stock replacement batteries for 5 years (source: Apple Genius told me). Mine was 4 years, 11 Months... Aside from the 'service battery' warning I was seeing wildly fluctuating capacity and a tendency to power down hard at ~20% - so aside from the physical risk you may also risk ...

I just had this problem - solved simply by resetting the SMC. This takes around 30 seconds - definitely recommend that you try this first.

We always want to keep good maintenance of our electric products, and to make it have a long life before retiring it. There is reason why Apple wants us to plug the power adapter first, as I believe they want to put the load on the circuit in the power adapter before the Mac. It also acts as a buffer zone. It is cheaper to replace the power adapter than ...

A-HA! I know this one! I just found out recently what to do about it. I have an early 2011 MB Pro and this came up. Baffled the crud out of me. Very simple fix, really. UNPLUG the charging cable and block from both the wall and the MacBook and just let it sit for about 2-3 minutes to discharge and, what I'm told, reset (something internal). After that,...

Fixed. Go into the security settings (Settings -> Touch ID and Passcode), and enable the "USB Accessories" switch (it should be green with the virtual switch-button to the right). This enables charging off any connection while locked. Unfortunately this also disables the privacy/security feature that thwarts hacktools with physical access, so if you enable ...

I too had original apple batteries and the orange light was flashing. I took carefully reinserted (rotated and cleaned the bottom and top of the leads) them and they seem to be charging now.

Strangely but possible, that Battery is End of Life. I know it is only 3 years old and has only Cycle Count: 564 it should last longer but it shows : Full Charge Capacity (mAh): 1708 Which is extremely low and indicates it is over for it. I have seen batteries with cycle count of only 100 but still needed to be replaced. So the cycle count is not ...

That will not work on MBA 2013, It has only one port where you can charge it (the magsafe plug). You will need new power charger for your MB Air 2013. About USB... till the USB/C came out the USB were only data ports (with 5 Volt) and could not handle the power needed to charge a Mac. To charge your 2013 MacBook Air you need 16-18 Volts input and ...
