Hi
I'm not sure if this is related to just my particular computer or a general charging bug. Several times I've plugged the Nexus 4 into my computer USB port to charge overnight (okay it's slower by USB but overnight it doesn't matter and convenient to use the computer USB port) only to find it hasn't charge but continued to discharged.
My computer USB ports are powered while the computer is in Sleep mode (suspend to RAM) and I've charged many gadgets over night with no problem, including the Nexus 7.
To replicate the bug:
1) Computer is on, plug the Nexus 4 in to charge, Nexus confirms it is charging by icon in notification tray and it will start to charge
2) Computer goes to sleep, Nexus 4 still shows it is charging, however at this point it is no longer charging, and actually starts to discharge quicker than normal.
3) While computer is still in sleep mode, unplug the USB cable from the Nexus, plug it back in, phone now starts to charge normally.
There seems to be a bug when the computer sleeps and disconnects the USB data part of the connection, the Nexus gets a bit confused and stops charging even though it still indicates it is charging. I suspect the faster discharge I've seen is because the Nexus 4 thinks it is powered and doesn't deep sleep as it would on only battery power.
An HTC One X, a Nexus 7, an MP3 player and numerous other gadgets have all continued to charge normally after point 2.
Thought it worth pointing out in case others have similar issues and wonder why the phone isn't charging.
Regards
Phil
Noticed the same just a day ago, went to take my phone off charging from my laptop and was very surprise/d/ that i had lost 2-3%

Same here with Mac. Once goes to sleep it drains phone even though icon shows its charging.
I've noticed this too. The Nexus 4 is my only device that won't charge from my PC while it's sleeping.
Edit: Actually I need to use the PC, so this isn't going to work
Had this happen too. Is there a fix? or is it just like that
Thanks for this. I wandered why my phone was 0% one night I had it on the charger all night.
Mine shows the charging symbol on the statusbar, but at the battery screen in settings it shows it isn't charging,
Screenshot included.
Screenshot was taken when my laptop was in sleep mode with my nexus 4 connected over usb.
Had the same thing happen to me.
Well, after JB update 4.1.2, the same happens with my GNex. So it must be OS related.

This is super annoying as that's how I've charged my phones for years. Now I have to put the stock wall wart somewhere and have an extra long USB cable to reach my desk. Sometimes I forget about this bug when developing stuff and it says "charging" so I wake up with a dead phone
I'd noticed this issue when charging with a battery pack, though I haven't tried it from my computer USB port yet. One thing - if the phone charge is above 50% it seems to be fine, it's only when it's below 50% that it doesn't recharge from the battery pack. Has anyone noticed something similar when charging from a computer USB - does it work if the phone battery is over 50%?
Same here--my Nexus 4 doesn't charge by a sleeping computer. Every other phone worked fine (though I had to connect my iPhones before the computer was asleep for them to continue charging after it was put to sleep). I've tried this when my Nexus was over 50% and with two different cables. It also worked with my Galaxy Nexus from OS 4.1 to 4.2.
I have the same thing when I try to charge it over a powered USB hub (you definitly get 5V from it) while the PC is turned off... It shows that it is charging but it is not.. really annyoing especially when you use it as your alarm in the morning (don't ask, that is how I noticed it the first time ). Never had a problem when the PC is turned on though...
something like this happens to me but charging with AC adapter...it would say connected to AC then after awhile when i wake the phone up, it would say charging with USB but it is connected to AC adapter...to get back to charging as connected to AC, i would have to unplug and replug...weird
Try different USB Ports and other USB cable.
I have a notebook which has on the left side 2 USB ports and on the right side 1 USB port.
The mobile doesn't charge with original USB cable on any of these USB ports.
But if I use a standard USB Cable and plug it into the USB port on the right side, mobile gets charged over night.
However, when plugging in any of the USB ports on the left side, it won't get charged.
(Left side is sharing the 500mA, right side won't)
And yes, my computer is put to sleep, just keep the USB ports alive
Yup is also happens to me. I think it is a bug, might as well use the mains as it works better and it charges very quickly.
4.2.1 has a lot of bugs that needs to be sorted out in my opinion, and this is one of them.

It's a bug with the Nexus 4. I have tried the same USB port with a:
1. Nexus 7
2. Galaxy Nexus
3. Galaxy Note
4. Motorola Charm
All except the Nexus 4 work fine charging when computer is in sleep.
Hi
Fingers crossed this is fixed in the next OTA happening shortly. In the change log we have this:
5194a3d power: charger: need sometime to handle the usb disconnecting events
Fixes listed here
A computer going to sleep would cause the data part of the USB connection to disconnect, if this event is now handled correctly by the charging system perhaps it will continue to charge normally after the computer has slept. Like I say, fingers crossed but looks hopeful.
Regards
Phil
A work around that most of you probably know is that as soon as your computer has been put to sleep, unplug the cable and replug it again. The phone will start charging again.

I was under the impression the charging capabilities of this phone were insane? My note 4 is charging very slow even with the phone off. Ive toggled the Fast Charge on and off (battery page in settings) and regardless of what i chose its very slow. I think my Note 3 charged faster than this. Is something wrong with my charger or my phone? Should i echange it for another?
Exchange it. With the included charger mine charges in about an hour.

The way fast charge works is with wall adapter and cable that came with phone and screen off. Another way is phone off. Takes a bit over an hour when phone dead
NOTE 4
Looks like I'll exhange it then, cause with the phone off, it took about an hour to go from 25% to 38%. Its strange cause my note 3 was usable while using GPS, and phone connected to car charger, not even a 2.1amp one and it would charge quickly. Note 4, actually went from 38% to 52% in about 3 and a half hours the same way
Mine is the opposite, charges fast and and drains fast. When I unplug it will go from 100% to 95% in 5 minutes with no use and screen off. I tried several battery app with no success to fix the problem.

Fast charge will only work screen off. If u using GPS then phone is awake and u get slow charge
Also make sure fast charge is clicked on.
NOTE 4
Did you take off the plastic stickers from the charger? Mine started fast charging after I did that. I think it was covering part of the connection somewhere.
I hope u connected to ac and not USB check battery in settings make sure it says charging ad and not charging usb
Yes mine says it is charging via AC. I havent removed the plastic from the charger, ill try it. The weird part is, last night i had 5 percent battery. At around 2:30 i turned off the phone and connected to the charger. I wake up around 9:30, a whole 7 hours later, and the phone only charged up to 89%. It takes 7 hours to not even charge full percent? Is that normal? Granted, if i turned off the phone or even had it on, my Note 3 charged within 2 hours or less even from dead. So i should just exhange the phone right?

Bad phone
NOTE 4
Have a nexus 5 qi charger (googles own) and proclip setup in car. When using the nexus 6 with google maps for navigation, phone is losing charge even while on qi. This never happened on my previous nexus 5.
Is the power draw on the 6 with screen on much higher than what the charger puts out? If so, this would be extremely inconvenient since I use my phone for navigation every single day.

yup, the power output of the n6 could possibly be much more than whats going in, while using the wireless charging plugged in via a car.
I would say so, my nexus 5 would lose charge while navigating and charging in the car too
Can anyone point me to an app that would automatically dim the screen when phone is charging? I can save some juice that way in the car

you need a high power car charger to keep up with the charging. USB charging and wireless charging is not going to cut it.
there are turbo cigar port adapters that you can pick up. I have one.

Not plugging in a phone each time I get in the car. Defeats the entire point of qi charging for me. I'm going to automate screen dimming when charging and see if that gets me to stable power while navigating.
Anyone have a recommendation for an automatic app?

the stock nexus 6 wired wall charger can put in as much as 2500mV(what the n6 takes in). my nexus 5 takes in 1100mV max. where the heck are you going to find something thatll put in that sort of charge, from in a car? by default, you will get less power than my nexus 5 maximum intake. it may say AC while charging, but in reality you are just getting a fraction of a full charge. keep it plugged in, not wireless, and it might keep the charge, and not drop.

Most car chargers only output 1 Amp, car chargers are available that can output 2.4 Amp. Getting a more powerful charger could solve your problem. See Link http://thewirecutter.com/reviews/best-usb-car-charger/

Yes, I have a 2A cig lighter socket in the car already. I downloaded the "automateit" app and set a rule to dim screen to 50% when on charge. Otherwise, I like the screen at 100% all the time.
We'll see if that solves it.

do me a favor next time you charge with it, grab the current widget app, and post how muvh voltage is coming into the phone. thanks https://play.google.com/store/apps/details?id=com.manor.currentwidget

I don't think you guys understand what I am saying.
Yes, I realize the N6 takes in a lot more mA's than previous phones.
Yes, I do know all about 2 amp cig lighter socket chargers.
Neither of those is relevant to my challenge. I use the phone for navigation extensively and I have a proclip dock + qi pad setup in both cars. I get in the car, and dock the phone. I am NOT going to get in the car and fiddle with plugging in wires. That's going backwards to 2005. That's going to a pre-Qi phone, which is a deal breaker for me. So, I either get the phone's power use while on Qi minimized to a point where its not draining while navigating, or I get another phone.
If I can't solve this, this is yet another major disappointment with the Nexus 6, for me. Frankly, I am regretting getting rid of my Nexus 5 so quick. The big screen on the Nexus 6 seemingly takes NUMEROUS sacrifices in usability with power draw being one of them.
my man...
Qi charging is SLOW! it you have gps running, which is a CONSTANT data connection, no trickle charge USB port power is going to keep up with that.
PERIOD.
keeping the screen off or muted/dimmed will not help if you have a CONSTANT data communication!
you need AC power to keep up with this type of battery discharge!!
same as if you are watching a video on your device. that is a lot of power being used (cpu, ram, screen, decode/encode file to watch, other things happening in the background) and no trickle USB port power can maintain a charge thats AHEAD of that.
qi charging is cool tech but its not yet ready to keep up with these types of demands.
you either use a turbo charger, high amp cigar port charger, in other words WIRES, to plug up the phone and keep it charged or stop using battery intensive applications.
Qi charging is not very efficient, there is no way you will maintain a positive charge while navigating, add to the heat issue, your phone could stop charging entirely. Qi is great for around the house or in the office but otherwise it can't really replace a physical connection.
I hear you guys. But I also know that my nexus 5 was used with a qi dock for navigation for well over a year. Thousands of miles. So I know its possible, maybe or maybe not with this phone. Well see.
I solved this. I am using the app called automateit and created two rules: when phone gets external power, I set the screen to 25% power and when external power is disconnected, I set it back to adaptive brightness. At 25% brightness, with navigation and use of an mp3 app and making calls, phone is stable on qi. In fact, it even charges at the rate of 1-2 additional percent each hour.
Is there a set of rules that it follows before fast charging works? I'm not sure if it's that or my phone or charger is bad..
Seem like I can only get it working 30% of the time. I would have to unplug and plug in multiple times before the notification pops up saying fast charging.
I tried multi USB cables and pushed it all the way in the charger.
I haven't managed to look at kernel source yet (not yet released), but maybe charge type is not only dependant on charging source type, but current battery level. ie top off charging. Just guessing for the moment............
I have the same issue. The quick charging notification never pops up the first time. If I unplug the cable and plug it back in, then it's fine. I'm using the wall plug and cable provided by Samsung.

Don't know. I've only charged my phone 2x, but fast charging popped up both times.

Actually no, I bought the T-Mobile version. I doubt it matters but it's the 64gb model. It sucks that you exchanged yours and have the same issue.

I picked up the AT&T model yesterday. Plugged into my car charger, 2amp, works fine. Got home and plugged in before bed with samsung supplied charger, showed fast charging. Passed out and woke up to 40% battery this morning. Turns out it will connect fast charge (ONLY if i use the supplied brick AND cable), but cuts out after about 5 mins! If i use the 9v brick with a random cable, it will just say cable charging, but seems to be decently speedy and won't stop charging. Seeing how crawldit replaced his and has the same issue leads me to think Samsung really was hoping people would get the wireless pad. Hopefully its a minor software update/patch needed. Phone is a freakin winner on all other aspects. Battery life appears to be better than the note 4 even with a slightly lower mah.
Definitely a software issue IMHO, from the sound of it. Also, on my VZW 32gig I do not have this issue. Every time I plug it in (to the supplied charger) it fast-charged. Cant say if it gives the message every time though, but I know it fast-charges because its never on that charger more than 15-30 minutes and the charge jumps massively. But even on a normal charger it still charges fairly quickly.
Well... turns out my brick was bad, used the one from my Note 4 with the new note 5 cable and it works like a charm. I'd recommend checking out a new brick.
Glad you got it figured out. Mine works fine now as well. I don't know if everything was overly stiff from being brand new, but after a day or two the fast charge pops up the first time every time now.

My OnePlus 7 pro would charge great in my cars USB using Android auto. My new OnePlus 10 pro doesn't charge at all using the same car USB port and original red cable. Ampre app shows at most about 260ma then immediately drops to about 50ma charging and an external USB monitor device shows .4 amp charging rate but driving with Android auto on a 1 hour commute, my phone charge % will drop by 1-2%. Anyone know what's going on?
I do not have an answer to this, but I have exactly the same problem. My last phone was a Oneplus 9 and the cable I used for that is doing exactly the same as you have described. I've only had my phone for a few days and just realised this yesterday.
State of Charge is largely voodoo.
0.4 Amperes is what your device is using including charging current.
50 mA is what is going into your battery.
1-2% is not statistically significant.
You need to take a 20 hour road trip to see if it maintains charge.
the same problem with the oneplus 10 pro, i come from the whole oneplus series being the last one the 9 pro and it was charging fine until now. I even changed the charger and it didn't work the same way, I took my car to check if the charge was working correctly and I deduced that it was the cell phone, but only with the car charger it doesn't work. I agree that it is a software issue not accepting the configured voltage.
