Not charging from USB

Since a few weeks ago, my iPhone 4 wont charge from the USB cable plugged into various computers. I bought another plug and tried with the USB cable in the same PC's. This worked for 4 days and now doesn't work again.
Any idea's ?

You may of damaged one of your pins in your docking port. Each pin does something different so some things may work (like computer sees phone and you can sync) but pin(s) for charging are damaged (or dirty).
Try cleaning your docking port of any debris or lint.

IPad not charging from USB

New iPad owner here. I was wondering if it's normal for the iPad to only charge from the wall charger and not via USB. It syncs up fine but I get the "Not Charging" message as long as its connected to my computer via USB.

I think it is weird that it doesn't charge to any USB-port except the ones on my MacBook Pro. I have USB hubs in my Apple monitor that normally have enough power to supply anything that needs power. I have a standalone powered USB-hub that gives a lot of power. But none of them will charge my iPad.
Other equipment will give you a message that it need more power than the connection has, why doesn't that happen when you connect the iPad to a USB-port that it will not charge from.
My two ports on the MacBook Pro are occupied and it is not an option to connect the iPad there and it is annoying to connect the USB charger and then later connect it to the computers USB-feed.
Not good!

My iPod Shuffle is not charging from USB

Hi,
My iPod Shuffle is perfectly operationnal when connected to my laptop thru a USB port. I can see it with iTunes et it syncs perfectly. The only problem, it does not charge. I see the yellow light flashing for a few seconds, while it syncs and then nothing.
I run Windows 8.1 on an ASUS laptop. I have disabled the USB suspension. Driver is not authorized to turn off the port to save energy.
When I connect my iPod Shuffle to a desktop computer (running Windows Vista), everything is fine.
Any clue?
Thx

I don't know where "fix" this will be (Microsoft, Asus, or Apple), but this may be what's going on...
When an iPod is NOT set to Enable disk use (or Manually manage music), iTunes only mounts the iPod's disk when syncing. The rest of the time, the iPod's disk is not mounted. There may be a "feature" on your laptop, and/or in Windows 8, that attempts to save energy by putting the USB port into a low-power mode, when the connected storage device (the iPod in this case) is not mounted. When iTunes unmounts the iPod's disk after syncing, it may look like an external storage device that no longer needs full power, even though an iPod needs full power to charge its battery.
When an iPod IS set to Enable disk use (or Manually manage music), iTunes keeps the iPod's disk mounted continuously. Therefore, the USB port stays at full-power mode and the iPod's battery is able to charge.
I know you said
I have disabled the USB suspension. Driver is not authorized to turn off the port to save energy.
but maybe that setting is not working properly (as it relates to iTunes/iPod), and that's the cause.
A desktop computer does not run on battery power, so it may not have this feature; saving energy is not a high priority when the power source is the wall outlet, not a battery. Or, Windows Vista may not have this feature. Therefore, the USB port gets full power whether the connected storage device is mounted or not.
One additional test you can try is to see if it makes a difference if the laptop's power adapter is connected or disconnected. When the power adapter is connected, the laptop has "unlimited" access to energy from the wall outlet (like the desktop), so maybe the USB ports stay at full power all the time.

IPhone 3GS will not charge from USB or charger

My iPhone 3GS will not charge at all - have tried different cables, USBs, wall chargers and still no success

Take it to the Apple store let the "Genius" run some diagnostics on it.

My ipod will not charge from a wall socket but will charge using the same cable if the usb end is plugged into a computer or an airport power source. My iphone and ipad charge fine on the same cable usin ghte same wall plug in the same wall socket?

My ipod will not charge from a wall socket but will charge using the same cable if the usb end is plugged into a computer or directly into an airport power source. My iphone and ipad charge fine on the same cable using the same wall plug in the same wall socket. This makes no sense but I see that it has been posted as a problem elsewhere. This must be due to some kind of degredation of the Ipod. . It is not fixed by IOS resets as others have noted.
Has anyone asked Apple directly about this?

Hi there Apples or Pears,
I would recommend taking a look at the troubleshooting steps found in the articles below.

I have also did various restores to the phones software/phone, it is running ios 7.0.6
Any help would be great I was trying to hold out for the iphone 6, and don't really want the 5s......

Then it's time to make an appointment at your Apple Genius Bar at your Apple Store. Apple will check it out and if it's defective and still in waranty (you don't say which model you have), it will be replaced.

Ipod video 60 GB won´t charge from USB

Hi my ipod won´t charge thru usb cable instead it will deplete the whole battery, I have tried connecting it in several ports, several computers and with 3 different usb cables with no luck, I noticed it will only charge thru my old firewire charger and dock, what can I do? When plugged into the usb cable it says "charging" but it does not.
I have resetted everything with no luck.
Thank you

I have changed it from usb ports I have putted it in different computers and nothing, when connected to the usb port of any computer back, front sides or wahtever it doesn´t charge it actually drains the battery, I have also drained the battery fully and let it off for 2 days and no still won´t charge from usb after 5 hours connected to the usb, it will only charge via a firewire charger or my monster cable.

5G will not charge from wall adapter

My new 15 gig 5G will not charge from a 5 volt wall adapter.It charges fine on the USB port on my computers.
So I decided to take a USB extension and cut it an place a current meter in series with the 5 Volt on the USB line.What I found is that it will draw ~500ma with the data lines connected in the cable(in other words a normal cable). Now if I disconnect the data wires so that I am only connecting the 5 volts from the USB port it will draw ~100 ma for a second and then draw no current.It appears that some kind of handshaking is required. Is this normal?
As it is now I will not be able to ever charge it from a 5 volt supply.Do they do something to the data lines on wall adapters?

Well I finally got my "dumb" USB charger (a Belkin F8Z009 Power pack) to work with my iPod 5G 30GB. To wake up the 5G needs to see 2.5 volts on it's data lines. The easiest way to do this is with a voltage divider made with two equal resistors. Like this:
As a poof of concept I made the device below with four 30K resistors but anything from 10K to 50K should work fine.
A more compact wake up cable could be made by cutting into a standard USB male-female extension cable and soldering in four resistors like this:
Of course if your building your own or can get your "dumb" USB charger open then the resistor voltage dividers can go inside.

IPhone will not charge from wall socket only from Laptop or Computer!

Just wondering if anyone else has had this problem?
My IPhone will charge sometimes and sometime it wont:
I mean like sometimes it will charge from the wall socket and sometimes it wont!
It will go so far as to turn off because of no battery life! Then I plug it in to the Laptop and it starts charging!

I have had this problem for some time. It applies to both a wall charger (the one that came with iPhone and a third-party model) and a car charger (third party). Both wall and car chargers are rated at 1000 ma which should be enough power. Yet when the battery charge goes below a certain level the phone will not charge from wall or car charger, but it will charge from a computer.
I did some research on USB power. Per specification, a USB client (the iPhone) cannot draw more than 100 ma from the USB host (charger or computer or hub) unless it asks for and gets permission to draw more current. (This is so it does not interfere with other USB devices connected to the host.)
Inexpensive wall chargers do not contain any computing elements. They short the D+ and D- lines together. This makes it impossible for a client to negotiate a higher current draw, so the iPhone, working per the USB standard, limits itself to 100 ma. When connected to a computing device such as a computer or USB hub, the iPhone can negotiate a higher current, up to the 500 ma currently allowed by the USB standard.
This begs the question, why can't the iPhone charge on 100 ma when the battery is almost completely discharged? After all, when the battery has more charge, the iPhone will charge nicely from a wall charger. Perhaps someone has some insight into this aspect.
There is evidently a new USB standard for wall chargers that will fix this issue. Both the host and client must implement in order for it to work. (I haven't read the standard, but suspect it involves the client detecting that the D+ and D- lines are shorted together.) Obviously, either the charger or my iPhone 3G don't comply with this new standard. Maybe the iPhone 3GS does? Or maybe we have to wait for another iPhone model that has the hardware that complies with the new USB wall charger standard.
Meanwhile I have to be careful not to fully discharge my iPhone battery when I am away from a computer. I recently went on a 30-day trip and had no problem because I charged the phone every night. Of course, I did not use it much because it was an international trip and AT&T roaming rates are horribly expensive.

New iPad 3 will not charge from a mac. need help on that

my new ipad 3 will not charge from a mac. need help why if any one knows? thk

The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

After using Energie On The Go BB will not charge from wall

My BB was out of power and I bought an Energizer Energie on the go to charge my BB and it worked fine. But since then the BB will not charge from the wall. I bought a new batery and same story. the plug con comes on when first plugged to the wall charger bt goes out in 3 sec. What's the deal? How can Fix? have tried removing battery and reseting several times but no luck.

I guess it's possible that the charger block is faulty, and maybe you had a power surge that knocked them out, perhaps the cables are good which is why they charge with USB port on computer of in a car but the block the USB cable plugs into is bad thus when using a wall outlet it doesn't charge... Have you had to reset the GFCI for any outlets in your home??

HELP PHONE NOT CHARGING FROM WALL ANYMORE!!!!

I had this problem last night i was checking my yahoo e-mail and preceded to download a picture to my e-mail as the picture was downloading the iphone locked up i was unable to do anything not even power the iphone off or get back to home. all i did was wait for the battery to drain down ( because the picture i was downloading was frozen and the light on the iphone stayed on) once i got home and plugged the iphone back in to charge ( beacuse battery went dead) the apple logo showed up and the phone seemed to be back to normal so i thought the only way it will charge now is if i have it hooked in to my IMAC. the icon for charging is working while hooked up to the mac but for the **** of it i tried charging from the wall (tried different outlets that all work) and the thing will not charge. it will only charge from the computer only why is this please help someone
IMAC G5 20" INTEL, IPHONE 8G, IMAC G4 17", IPOD 60G Mac OS X (10.4.10)

Same thing happened to me. Suddenly, I could not charge from the wall outlet. To test it, I also tried to charge my iPod from the unit and it didn't work. Went to Apple Store and got a new USB wall charger, even though the Genius guy gave me a hard time and was convinced nothing was wrong with my charger. He exchanged it, I took the new one home and it works perfectly.
I have read that other people's chargers are defective, too. Hope this helps.

Ipad 2 won't charge from ipad charger, but will sync and charge from USB!

Hi
I have been having some issues with charging my Ipad 2 and have searched the internet but can't find a solution.
I can charge and sync my ipad from my computer but it will not charge from the mains charger (2 amp) provided with the ipad. - Therefore there is no problem with either the lead or the pins on the ipad
I know the cable works as it is the one i am using to sync to the PC. The charger also works to charge my iphone. - Therefore no issues with the charger.
I have rebooted the ipad.
I have also restored the ipad back to its orignal settings and restored a back up from Itunes.
All so far have had no effect on using the charger to charge the ipad.
Perhaps a trip to the Istore is the only option?
thanks
