Faulty charger? - Nexus 10 Q&A, Help & Troubleshooting

I my nexus turned up with 66% battery, I toyed with it all day and at 4% decider to charge it. Only to find out the charger didnt work!
I narrowed it down to the cable itself, and being a brand new cable I couldn't quite get it. Looking in the end of the smaller USB I can see there are only 4 pins, the one I am using from my galaxy nexus has 5 could this be why? Does everyone else have all 5 pins?

I was about to post and say that micro USB should have 5 pins... But then I actually looked at my n10 cable and it does only have 4. Pin 4 is missing (second from the left if you treat the longer side of the connector as the top). makes sense I guess, pin 4 serves no purpose in this type of cable.

Mine has 4 pins too.
What you should do: try charging a phone with charger
Or try the cable with a phone to a pc. That will tell if it's the cable.

Backlight started flickering after being plugged into Motorola charger

I charged the phone in my car for about 10 minutes today with no issues. When I got home and went to bed, I plugged the phone into my charger that I've used forever; a Motorola charger that originally came with my wife's old BlackBerry. I use it because the cord is about 5ft instead of 3 which seems to be the norm these days.
I didn't look at the phone again for about 20 minutes. When I did, I noticed that the backlight was flickering like crazy and that the edges of the screen were bleeding. When I unplugged it to get a closer look, I freaked out. Over the next few minutes, the flickering went away and the bleed disappeared. I couldn't even get a picture or video of it. I got the OEM charger out of the box and am using it now with no issues.
Weird.
You were using a charger for another phone? Wow man, never do that.

My phone flickers from bright to dim when I use my car charger. Most likely the cord's teeth to hold it in the phone are worn out/flush against the head of the charger. Replace the old cord with a new one and it should be fine.

I do that with every phone I've had with no problem. I have random chargers plugged in all over my house and I use other people's chargers at work too

It kind of looked like this but about 5x as intense. Not my photo.
Probably something to do with heat, as you were using a different charger.
Nexus 4 is glass after all, so it generates even more heat.
Well you have been lucky if you just use any charger around unless you are sure they are the correct voltage etc. They are all probably similar though seeing as they use the port that plugs into a USB. Still I wouldn't do it across manufacturers.

I am sure they are all close but it is still taking a chance and will void your warranty for sure unless you lie about it..

I always use different chargers. Mine are a mish mash of all kinds. They all usually output 5v and 1Amp or there abouts.
Living room - Sony charger with blackberry USB cable.
Living room - playbook charger
Bedroom - HTC charger with archos USB cable
Kitchen - Samsung charger
Work - HTC charger with Nokia USB cable
The playbook charger outputs 2Amps and that is fine too.
The only charger I have ever had and issue with on any phone is an LG one I got with an optimus 2x. That used to cause BSOD even on the LG.
Whether it voids your warranty or not, they would never be able to tell what charger you had been using.

glass itself does not generate heat
Same thing happened to me, except on the stock charger but it has something to do with overheating. Mine is recovering, but took a while and is still showing some ghosting.

Using my Nexus S and 7 charger on 4?

Would this be a safe idea it terms of the life of the battery down the road? I also bought a 3rd party car charger.

I use chargers from various phones. Have used different phone chargers with all my phones. Never had or noticed any problems. I'm sure you will be fine.

Yes, it's safe. I'm using an old Samsung charger to charge my Nexus. The charger doesn't really matter IMO.
Sent from my Nexus 4 using xda premium
When using chargers that don’t come with the device, the only difference it can possibly cause is the rate of charging (how fast your device charges).
Just take a look at the milliamp rating on your charger. The N4 comes with a charger that outputs at 1400ma. I found that if I charged my N4 with a charger made for SE Arc, it takes forever to charge which isn’t a surprise since that charger outputs 750ma.
Don’t worry about using a higher milliamp charger on a device that’s rated to charge at a lower rate. The device will only draw what it needs. I’m not sure what’s the maximum ma the N4 will charge at, but let’s assume it will charge at 1400ma maximum. Even if you use a 2A charger, it will still charge at 1400ma.
Even I thot its safe and was using my Nexus 7 charger with the Nexus 4 . everything was fine for a few hours. Then suddenly it froze and the screen started getting weird lines on it .I immediately removed the charger and while the device was rebooting I could notice that the screen had a burn in kinda image on it. It slowly faded away later. Haven't used the Nexus 7 charger since and I've never got the same issue again.

I don't think so. Cuz I wasn't even using it. It was just lying there most of the time. I switched on the display and was looking at battery monitor widget to check the charging status and then maybe twitter or something and it just froze. Held down the power button for 10seconds then restarted it.

As a rule of thumb I'd keep then Nexus 4 away from the Nexus 7 charger.

The N7 charger is rated at 2A. I sometimes use it to charge my N4. Most of the time, I use a generic 2A charger. At the office, I use a Samsung 2A charger for my N4. I’ve encountered zero problems.
Truthfully I'm more concerned using a 12v in the car. Any suggestions what I can get?

[Q] USB Cable damaged

I think my USB cable which came with the stock charger is damaged. On the micro USB end, what's supposes to be in the middle/center is now sticking a little out. (I say again on the micro USB end, the one you stick in your phone. Should I replace the microUSB cable and keep the charger?

Does it work properly?
Yeah, works. I went out and bought a a micro USB cable, but it charges much slower than the stock one. Can one of you take a look on those photos and tell me if the jack is okay?

Does your phone charge? Also when you put your cable in your phone does it seem to stick out or does it look flush.
If it looks flush and if it's charging and there doesn't seem to do any damage to the actual phone I wouldn't worry about it.
My samsung charger, the actual USB cable is bent and it still charges just fine and doesn't affect my actual Micro USB slot for the phone.

It looks OK. I can wiggle it a tiny little to the right and left though. I wasted damn 12 euro on that new cable (I know I overpaid, I just wanted to charge my phone safely, ironically it just charged it slow as hell. The cable looked a bit cheap anyways.. I'll just give it away. )

Pogo pins charging at higher rate.

Recently my wife broke her USB port on her n7, so I decided to just attach some wire to the pogo pins as I know there was a ground and a 5v line. After I installed battery monitor, hers was charging at 1000 to 1300ma. Mine charges at 500-600ma.
Maybe my port is broken too I'm not sure. Can anyone confirm this?

Hi I use the dock to charge my n7. I have noticed a faster charging rate. However i do not know how to measure this

I also charge my nexus from a homemade dock at the 1000-1300 mark compared with my usb port. The usb port is so bad that most of the time I see it discharging while in use!!!
I believe this is a hardware fault as mine used to charge great through usb. at one point my usb socket stopped working altogether, I ran a soldering iron over it and it is at least working again, still slow to charge.
I have also been following a thread about this in the google user forums. One person stated that when they changed the usb board charging rates resumed to normal standards. There is a lot of people in that thread suffering from this. Bad show google.
Have you guys confirmed that the n7 charges faster off the pogo pins?

It can charge just as fast off USB I know mine does I think the problem seems to be that the ports are easily damaged and it slows the charge rate

I have been following a thread on google forums about people suffering from poor charging rates. I can confirm that many users in that thread, myself included, have found that charging through pogo pins charges normally, whilst the usb charging takes forever and even discharges with screen on!!

is that with the provided 2 amp charger?
It is with a third party charger as my charger broke, but it was the same with the original.
Sent from my Nexus 7 using Tapatalk 2
The 5V oem charger output 2000mA. Any charger 2A should fast charge.
Also the pogo pin can charge on 12V 500ma (which is automobile acc. standart)
See more info on Qualcomm FastCharge Standart
There's a chip that identify the power output available. So a charger 1A charger will be identify by the device, therefore it won't fastcharge.

[Q] Nexus 7, i have a problem with power charging

My nexus 7 have a problem, that can turn o, every time rebooting, won't accept any charge, how can be?
...i have almost the same issue with my 2012 N7, stock&root....it just will not charge (tried different chargers!) It shows "charging" but it uncharges...now it is dead!!! ....a known issue??
Sent from my Nexus S using XDA Free mobile app
Sounds to me like you either have a broken lead on one of the charging pins inside the MicroUSB charging port or either your battery has malfunctioned.
I also have the Nexus 7 2012(grouper) and have a "tighter" connection using my Samsung ATIV SE MicroUSB cable, but the cable for my Galaxy S4 tends to fall out easily.
Remember that most aftermarket MicroUSB cables do not have all the pins inside the connector and most MicroUSB Chargers only have the 5V charging pins..
Try plugging your tablet into a USB port on a computer and see what happens..
Hope everything works out!

I have changed my usb-port as well, and the battery icon when the tablet is shut off shows that it is charging, however the OS when turned on doesnt seem to recognize that the charging cable is present. Also PC connection doesnt seem to work... Any ideas?
