A Strange Problem with my HTC Vision

I plug it into a wall charger. It charges.
I plug it into a PC. It charges.
I plug it into the car charger. It doesn't charge. I plug another device into the car charger and that device does charge. Same cord, same car.
I have a special device that I plug into my car lighter socket - it gives me two wall-like sockets and another USB socket. When I plug the Vision-attached wall charger into the device, it charges. (This device is similar to this http://amzn.to/JeJjGo).
Also - I've done all the above on different cars and tried different car chargers. What's going on?

It's not the charger. The charger charges other cell phones, Bluetooth devices. I tried three different chargers.

I have usb cables that are cheaply made and good ones. Cheap ones will work with some devices and not others, good ones work with all. You may have a cheap one that works sometimes, when you have a usb port that is slightly damnaged it may not work with this sometimes usb ports are picky

He has a point here - you should at the very least try another car charger and see if it works. Seems like the car charger and your phone just don't mix well.

It's definitely your USB cord. I had the SAME problem. My car charger would charge my Bluetooth, and my girlfriends phone fine. But when I plugged it into my G2 it acted like nothing was plugged in at all. I would get another car charger ASAP and stop using that junk! It's just going to mess up your devices in the long run.

Nexus 7 doesn't charge when on, but charges when turned off?

It's really weird. When my nexus 7 is on, it won't charge or connect to the pc by usb, as if the usb port doesn't work. When I turn it of it charges normally, not problems whatsoever. I tried with factory cable and charger still same issue.
I don't have the receipt to return it so I have to find a fix, any ideas?
Raplacing the usb port might do the thing or is it something else? Is someone having this issue?
Thanks

You don't have enough power on your USB port. Mine charges via usb just fine while in use. My car charger does what yours is doing.
I'll assume it charges fine when using the ac charger that came with your n7?
Why you can't connect to your PC...I don't know. Like you said...maybe a bad USB port. I'm using an Asus USB 3.0/SATA lll PCI card.

My nexus 7 won't charge at all when it's on. It charges normally when of with any usb/adapter, but when off not charging at all with any usb/charger even oem one

Read the documentation. It does not support charging over USB while in use. There's not enough power through a computer USB port.

It doesn't charge even if I plug it in the wall. I have to turn off my nexus to charge it!

I have the exact same problem. Mine won't charge when on and will not connect to PC via USB. Did you ever find a solution?

I had the same problem, it turned out to be an iffy USB cable. Grabbed one of the kids micro USB cables (for their phone). Fixed the issue for me.

Doesnt matter what kind of cable I use or charger. Cant get it to do anything but Stickmount still works somehow.

Sorry to dig this out. Have the same problem as OP for a few month. Now I'am annoyed enough to find a solution.
Anybody with good advice?
Cable/charger won't matter: if GN7 is on (either active or standby) it won't charge (or get recognized by PC). If switched off, it charges anywhere (wall mount charger, PC USB, ...)

I'm also having this same problem and have been unable to find a solution after about an hour or so.

I didn't find a solution. Sold on cl for dirt cheap. Bought an n7 2013

same problem
I bought my n7 on 11-30-12. In the last month or so its developed the same problem. I called Asus for warranty. The guy says you can send it to Texas for it to be studied and repaired but it will take a LLLOOOONNNGGGG time. He said I should wait til the factory warranty ran out and hope Wallyworlds extended warranty offers to replace it with a new one. I tried taking the back off and unplugging-replugging it, didn't help. I tried a factory reset, didn't help. Guess I'll keep trolling the interweb for ideas til the end of the month and hope Wallyworld gives me a new one! Either way its the last asus for me. I may have to sharpen my teeth for all the crow I'll have to eat when I show up for a visit at my brothers' homes with an ipad air...

I had this problem with my Nexus 7 (2013). In my case, the usb charging port on the tablet was severely damaged. This caused the USB port wires to short with each other. USB charging was obviously not possible. However, the unit would charge with the wireless charger--but only when off.
Since I had a wireless charger, and the USB port was destroyed already, I took a hemostat clamp and physically snapped and removed the USB charging port and wires. Once the USB wires were no longer shorting, the wireless charging worked flawlessly.
If you don't care about USB charging or connectivity, this workaround may work for you. Otherwise, you may consider a daughterboard replacement or replacing the USB port.
Hope this helps...

You need a good wall charger, a USB port on your computer isn't going to cut it. Buy one of the high power ones from Amazon. I find mine will hold at whatever level it is at now with my Kindle's wall charger if I'm using it but will charge pretty quickly when the screen is off.

I know this is an old thread but I acquired a nexus 7 2012 from my sister. She said it doesn't charge. I did a factory reset and found that it charges when it's off and holds charge so the battery is out the equation. I purchased a new usb port and fitted and although the USB fits a lot better it still only charges when it's off. I've used plenty of wall chargers Sony, Samsung but won't charge when it's on at all. Anyone get to the bottom of this?
Thank you

This is an old thread, but I have the same problem. My N7 charges only when turned off no matter which cable or charger I use.

[HELP!] Would not charge over wall charger!

Hello all.
I have had Nexus 4 for 2 weeks now. Absolutely love the device. Doesn't really have any problem with it. Last night, my phone didn't charge when I plug it in the wall charger (LG charger with Kindle USB cable). So I thought I forgot to charge it. I plug it in the wall charger at work, a HTC charger/USB cable. It is still not charging.
But if I plug it into my laptop, it chargers and I can transfer files between the phone and laptop.
I haven't even rooted the phone yet. Locked bootloader. Stock everything and the latest update.
Noticed that there is something similar going on with S3. So this is not a Samsung problem. It's an Android problem.
Any help is appreciated.
EDIT: Nevermind.
I think it's the charger's fault. Glad it's not our phone though.

Have you tried using the wall adapter and cable that actually came with your Nexus 4?

the wall adapter was from LG. I don't think the USB cable is faulty since I can connect to Laptop ok.

You should try the wall adapter and cable that came with your phone just to be certain the phone is faulty. Different adapters have different current outputs and different cables are better Suited to handle larger or smaller outputs. The kindle cable you speak of I know for sure is not designed to consistantly output at higher levels. Also, Older Samsung wall adapters like the one that comes with the Epic never had enough current output to charge my HTC phones anywhere near as quickly as my genuine HTC wall adapters.

Does your charging change from AC to USB?

My nexus so far seems great but i have this issue and idk if its a defect or idk? When i go to charge my phone with the stock AC adapter and even a HTC adapter it starts charging on AC then sometimes switches to USB and charges slower. And I have to like plug it in and out a few times for it to finally catch as AC its super annoying and my GNex never had that issue. And when i want to use the phone on AC the Charge Drops significantly sometimes discharging and im not even doing anything intensive. Does anyone have this issue? Is it a problem with the USB cable maybe? Or do you think this is a defect? Because its about to be 14 days and i dont have much left to get an RMA cause its what im considering and if I need it i dont have 380 dollars in my bank account either if i do need it so idk how that would work. Any help would be appreciated Thanks!

It lowers the incoming current, by dropping to usb charge, to help keep the battery cooler. They seem to be really trying to keep the battery temp down on this thing.
Ordered my Nexus 4 on the 13th. Still waiting.

Really? Do you know the temps? Or does anyone? Cause sometimes it changes to USB after plugging it in for like 5 mins and i wouldnt think it gets that hot that quick. And when i finally get the AC to seem to stick the temps go up to 30-35 degrees celcius as normal and im getting around 850mah and it doesn't drop to usb charging it just drops current sometimes mainly when im using it obviously. So idk if it really is what you say or maybe someone could elaborate more?
I just want to get to the bottom of this issue so to know if i need to get an RMA :/

I forgot to mention that it also seems to randomly switch between AC/USB/UNPLUGGED really fast sometimes and i have to unplug and replug to get a charge I have no idea why.. I really want to know if its a software issue or hardware. Thats my main concern.

Woww this makes sense Ive been trying to figure out why this freaking thing was taking so long to charge. this reminds me of the galaxy s and how long that thing took. hopefully this is a software bug and they can get this thing worked out

Yea idk if its a hardware or software bug im hoping software but i may just do an RMA incase if i can ill call google tommorow. And if you want to check how your phone is charging you can download Battery Monitor Widget it shows the mah and all that.

I have that same problem with the charger that came in the box.once it goes to USB it take forever to charge but when I use the charger from my gnex it stays on ac and charges really fast not once does it goes to USB.so I tried the N4 charger on my HTC thunderbolt and gnex and both would go into USB mode and charge really slow.

For what it's worth, my Nexus 4 *NEVER* charges in an AC mode using the OEM charging plug, regardless of which power point / cable I use with it. And to charge from 'critical' to 100% took about 7 hours last night. Wtf.
It's been RMA'd as I don't believe this to be correct behaviour. Perhaps also related, the USB computer connection has stopped working. It'll charge via USB but won't connect to any computer.

Hmm so did you use the Gnex charger like the USB cable and AC adapter? Cause ive just used the ac adapters with the N4 Lg USB cable. It makes me think that the USB cable is **** to. I need to find another USB to test this out.

Yep, tried a whole bunch of different power sockets, usb charger plugs and cables. Still screwed. The more I read, the more its obvious that the devices behaviour isn't correct.

You should send it back because mine charges fine. It takes 2-3 hours to charge mine to full from empty. I'm using the charger and USB cable that came with the phone.

I'm actually facing the same thing, I slept for 3 hours and woke up to my phone being only 60% charged. I tried plugging it in and out a couple of times, and now its back to AC and not switching to USB anymore.

In using Franco kernel and even enabling USB fast charge doesn't keep it from showing USB.

I was looking at my LG charger and it seems to be missing one of the gold connectors on the male part of the cable Idk if this is normal but my gnex has all the gold connectors.

Yea mine is missing it to I wonder if that is why? And i just got my RAVpower external battery and that usb has all the pins and i tried to charge my phone with the lg brick and the ravpower usb and it seems to charge fine goes to ac every time. So im really wondering if its the LG USB that i got and it being faulty or not. I need to get another USB to test this out. Cause i dont want to swap out an entire phone for just a usb..

I've noticed mine charges as USB when using the stock LG charger. I had put it down to the 3 metre USB cable it was attached to, but I guess it's just a pants charger.

I just started having the same problem since Sunday. Had the phone for 2wks now. I had the same problem with my gs2. I really don't like these adaptor charger now a days. I go for the straight wall charger. Seems to work best. I think it's better because it doesn't convert to a usb cord as well, I don't know but I went ahead and ordered this one. http://pages.ebay.com/link/?nav=item.view&id=150959459340 should be here Friday. it says original OEM charger for E960 nexus 4. We'll see.. I suggest direct wall charger instead of those USB adaptor that come with phones now.
I just looked at my USB charger from lg, it has 4 gold pins. Seems like they're all there, how many are there suppose to be??

I'm not having the issue ... But it happened to me when I had my s3 I would use oem Samsung home charger and it would charge for a bit and it would stop ...

That actually sounds like a good idea and should hopefully work! I need to order one. Still debating on Getting an RMA cause i dont want **** phone or worse phone..
Correction And it should have like 2 gold outer pins and 3 gold inner pins and mine and I guess a few other people have the outer pins but only 2 inner pins im missing the left most inner pin.

N4 Charging unstable?

Sometimes when I charge my phone I get spikes of charging then not charging. Wonder if this is a problem with the USB port or its just a dust issue there?
Sent from my Nexus 4 using Tapatalk 2

I think this phone just has a retarded charging port. The plug doesn't stay in securely which causes the phone to charge slow, first of all. And I recently started having the problem you described. It will say charging, not charging back and forth a bunch of times. Are you using a case? When this happens, I take off my case to make sure the plug is in there securely and I also make sure the AC adapter is plugged into the wall securely and that the USB plug is plugged into the AC adapter securely as well. This usually helps.
Charging this phone is such a headache sometimes.

That happened to me like a month ago and the charger was the culprit. But I also had slow charging (even with the wall adapter, it would eventually change to USB charging) and it wouldn't reach full charge. You might want to try another charger, just in case.

I have to agree. I am using a different charger because the one it came with sucks. I would wake up to a phone that had 50% even though it was on the charger all night.

My Nexus 4 does this when I use the LG USB cable, but I don't remember if it happened with the stock charger. I lost that a long time ago, and now I use the charger from my old Motorola Atrix, which works fine if I use a cable other than the LG cable. I think my cable is damaged, but it feels like the cable always did that. If I plug my dads Atrix HD into the LG cable, it does the same unstable charging as my Nexus.

I have the same issue, have tried multiple chargers and cables, even happens over Qi.
I have a replacement phone coming

Had this too, charger was broken, just try another charger first.
I'm now using a standard samsung charger

I had this problem with the official charger, but it works well when I charge it using my computer usb ports (I prefer lower current when I charge over night) and the Nexus 10 charger.

Thanks for all your responses...it seems to be better now after cleaning the ports....but still happens sometimes...I'm trying to do a RMA for it but have a question...what if during their testing it didn't happen would I need to pay for the replaced device?
