I seem to have an issue that my phone never charges whilst connected via USB to my Macbook Pro. I have also tested on a Windows machine and have the same issue.
I was able to charge my Sensation over USB and I know that one of the ports on the Macbook has a higher output for charging but it makes no difference.
The phone states that it is charging but the percentage charge continues to drop. If I switch the power off it will charge. There doesn't appear to be any big battery drains though. I ran for a day and twelve hours over the weekend and charged at 40 percent.
Has anyone else the same issue?
Btw, I am on stock 4.0.2, rooted but not running anything else that should have any affect

How old is your macbook pro? Or more to the point, do you know if it has USB 3.0 ports? If your higher output ports are just 2.0 (and your computer is describing them as such compared to the older 1.0 spec) then you are stuck at 0.5A (half of wall charger output). USB 3.0 goes up to 0.9A, but I don't know if there are any catches in terms of devices needing to request the bump.
When you say that it charges if you switch the power off, do you mean it only works if you actually power down the phone? As in, leaving it sleeping plugged in, it still won't charge? Keep in mind that actively using the phone with the brightness turned up high could result in overpowering the .5A current in.
Unless you know someone else with a GN you can test you might just want to take it into the store and have them try it there/consider a replacement if it's defective. Also worth exploring if it's just the battery is defunct, if you have access to another one.

Really? Source?
Doing a tad of research it seems some models front (closer to the front) USB port has slightly higher output than the back (closer to the screen) USB port because the back one shares a USB controller with internal components.
It couldn't be noticeable though, they're both simply rated at .5A .

I charge my 4.0.2 stock GSM Nexus off of my MacBookPro almost every night without issues. Using both an HTC cable and the Samsung cable.

MacBooks don't have USB 3.0. Its always been standard USB 2.0 afaik.
I'd also recommend that OP check different cables and computers, or different batteries if possible.
I have the exact issue. If I charge via USB on ANY laptop/computer it takes forever and if I'm using the phone as it's charging it uses more power than being supplied so it loses battery life even though it's plugged in.
I had this problem on my iPad too. It seems they need more power to charge but can still "trickle" charge off of a standard USB port.
My batter was at 10% last night, plugged it in to my laptop and sent some texts and left the display on (dev settings), about 10 min. latter it was at 4%.
I mean to post this last week!
See the screenshot....Status 'Charging' however as you see from the lower part of the screen, it has clearly stopped charging some time ago (about 3 hours earlier!)
It turns out that the CABLE was the issue....I thought all Micro USB cables were created equal, evidently not
Any ideas what the differences are in micro USB cables and how to identify which ones 'work' and which don't? I bought 10 from ebay which all seem not to charge from USB
I've had no problems charging via my pc using Samsung or Motorola cables. It charges slower but it still works.
Any way to disable rapid charging?
I have a generic USB extender and used it to extend my charger cable by a couple of feet. When the phone showed "full charge in 5 hours" I realized it's making the charge speed extremely slow. The USB cable is a regular sized USB male on one end while the other end is a regular sized USB female. You could use that to slow down your charging to about the speed you'd get by charging from a USB 2.0 connector on any PC/laptop.
One the same note will using a standard charger from other cell phones (that I have like 300 of) and the cable that came with phone cause any problems or just charge slow. I travel a lot and have several USB devices I bring and don't want to bring multiple chargers if I don't need to.
Thanks.
It will just charge slow.

You need a compatible charger for it to fast charge. Using a regular charger wouldn't put it in that mode. I wanted to know if there was an option to turn it off with a compatible charger.
Why do you want to turn it off.
I could swear I saw something in the framework to disable fast charging but I'm not 100% sure.
I'll try to remember to keep an eye out for it after the December updates drop from Google and I have to redo my framework mods.
As far as options in the GUI go, I don't recall ever seeing any option to disable fast charging.
To answer another question, someone may want to disable fast charging to ensure their battery lasts longer (short term + long term). Or to prevent overheating when charging in the sun. And other reasons too.
You could always buy a MicroUSB to USB-C adapter. Or the phone may have come with one too now that I think about it.
Then use an older MicroUSB charger to charge your phone.
Charging via computer is only like 500mAH compared vs. 2000+mAH charging from the stock charger.
Count me amongst the club who would prefer to slow-charge my phone overnight at least.
And possibly slow my car charger down to maybe just 1000mAH to prevent overheating while the phone is docked underneath my windshield under the hot sun.
My Pixel C tablet does not start to charge immediately when I plug it in to any charger. It registers that it is plugged in straight away, the battery icon changes straight away to the icon with a lightning bolt and the Ampere app registers as being plugged in, but it does not start charging. The battery information screen says 'Not charging' and ampere says the battery is still discharging. After about a minute this usually changes and the tablet does start charging, but a couple of times it has not charged at all while registering that it has been plugged in for half an hour.
This happened with my brand new tablet, so I returned it and the second and third replacements have been exactly the same. This happens using different chargers and in different locations (I have tried different sockets around my house and at work).
Has anyone else experienced this? I am about to return my third tablet for a refund as I don't want such an expensive device that I can't trust is going to charge.

Mine does this. I just chalked it up to new USB C charging standard and it calculating what to pump in to the battery before it begins.

Has yours ever not started charging eventually? That's what made me call Google support and the four people I have spoken to there all say it not charging immediately sounds like a fault.

It has always begun charging. Hell, maybe mines faulty too, but I never thought of that.

Mine does this, I wondered if it was a USB C thing too. when I plug it in the charging icon appears immediately but Ampere shows plugged in/discharging, the discharge rate starts low at approx 300mAh and over about 30 seconds rises (drops?) to, for example 1750mAh before flipping to displaying charge at 1750mAh. The final plugged in/discharge rate always matches the initial charge rate measured.
I usually charge using an Anker multi port charger and USB A to C cable. it behaves the same but with higher numbers with the Google supplied charger.
I am curious to know if USB C negotiating its best charge rate somehow fools Ampere?
I just bought a Pixel C and I am using it with a generic 5V /2A charger and a Dash usb C cable. It does the exact same thing that the OP described. I have to plug the USB end of the cable into the charger once or twice, before it starts charging. If I just plug the tablet in normally the lightning symbol appears and it does not start charging.
USC Type c takes 10 secs to negotiate. I would not use other chargers or cables. Stick with stock or known tested working ones. Refer to this spreadsheet
https://docs.google.com/spreadsheets/d/1vnpEXfo2HCGADdd9G2x9dMDWqENiY2kgBJUu29f_TX8/pubhtml
Remember ampere is not accurate and is only a best guesstimate. I recommend using current monitor in conjunction.
Becareful using generic cables and chargers risking frying your devices. If the cable is not made programmed correctly missing emarker or same for charger, USB Ttype C Power Delivery cannot not negotiate correctly. If it's missing altogether it may overcharge..
I've found the Pixel C to be a little picky with its chargers but the only really big disappointment was with the Pixel phone charger. That charger is supposed to support Power Delivery and can charge faster than the Pixel C charger can so I naturally plugged it into the tablet and it is useless! It connects and disconnects continuously so it never accomplishes any charging and the screen will not stay off. You'd think a charger and a device designed by the same company, advertising the same USB charging standard, sharing a marketing name, would work together!

You might have a defective Pixel charger or cable, it has been known to happen. That is why people have gotten replacements.
On that note consider that the Pixel comes with the same charger as the XL, but it doesn't charge at any faster rate than 15W with it's own charger..

Yes, I have heard that the Pixel-xs doesn't make use of the higher voltage (9v, I think?) charging option, but I was hoping the Pixel C would. It is known to work with other higher power chargers. Maybe I'll call up the old Google and see if my charger is bunk. Even if it is no faster it shouldn't cyclically fail to auto negotiate like it does.

The Pixel C is 5V/3A 9V/2.67 12V/2A. I use both the Xentris/verizon USB-C/QC ($9-40) and Targus 45W ($30-55) chargers, both charge my Pixel C at 24W 12V/2A. It's great.
I have just purchased the Belkin charger cable that is on the Google list. The tablet's behavior is still hit and miss on the 10V/2A chargers that I have. I am using the Samsung S2 charger (should be plenty good quality). I am not even looking for fast charging or anything, just consistent behavior. If I plug in the usb C end of the cable ampere starts to show a discharge rate of like -500 mA and it does not start charging. The built in battery indicator says USB Charger = not charging. This happens about 7 times out of ten. In the other 3 cases it starts charging when the USB C end is plugged into the tablet. If I look at Ampere and see that is does not charge for like a minute, then I unplug the USB 2.0 end of the cable from the charger, re-insert it and voila it starts drawing 2000 mA immediately. I have tried 3 different chargers so far and the behavior has always been the same.

The Pixel C uses USB Type C Power Delivery 5V/3A 9V/2.67A 12/2A. 24W max
Ampere app is rather useless and just for reference. (note I use it often) Try Current Monitor. Regardless both rather useless, since the Pixel C doesn't negotiate faster charger until after the screen turns off. So while you have the screen on looking at Ampere/Current Monitor, you're gonna get a fluctuating reading that doesn't make sense. I use a kill-a-watt to see the wattage being pulled.
I am able to get a solid consistent 15W charge out of the stock OEM charger. I can get anywhere from 15W (screen on) with my Xentris/verizon and Targus 45W chargers and 24W (screen off).
Also note USB-c is not consistent, it negotiates different levels and it always changing depending on several conditions, like battery level, temperature and if screen is on at the time.
I've attached some results using LG V10 OEM Charger, Samsung Fast Adaptive Charger and Asus Nexus 7 charger with USB A to C with 56k ohm pullup resistor connected to the Kill-A-Watt for reference.
My HTC 10 is about 1 year old, and I've never saw it show the "charging rapidly" message. It always charges normally, but I think that, somehow, the quickcharge thing is not engaging.
To clear my doubts, I've purchased a USB tester (model J7-t), and found out that the phone is charging at 5.08V 1.45A, with factory original charger and cable. With another charger (a regular 2.4A charger) and another cable, it charges at 5,22V 1.45A.
With phone turned off, it charges at 5,10V 0.96A.
I've tried some tips from other threads, like turning the cable over (I assume turning over the USB-C part of the cable), cleaning the USB-C port, restarting the phone, to no avail.
It has no problems connecting to the computer for data transfer, it also charges from the computer USB port.
It's running stock Oreo with stock kernel, rooted, bootloader unlocked and S-ON. As it is, takes over 90 minutes to go from below 20% to 100%.
Is this normal? Anyone knows why it's refusing to quick charge?
__________
EDIT: I suspect that the culprit is the cable itself, a HTC brand cable that came with the phone. It may not be compatible with Quick Charge technology.
I researched a bit about cables, and ordered a couple of these - https://www.aliexpress.com/item/Bli...r-Cable-1m-1-8m-Mobile-Phone/32833209044.html
BlitzWolf USB-A 3.0 to USB-C model BW-TC9. The description page says that it has a 56kΩ resistor, allows data transfers up to 5Gb/s, supports Quick Charge technologies up to 3A, and is sturdy enough to tow cars without breaking. Not that I would ever tow a car with an USB cable ...
Will update this post when the cables arrive and I test them.
__________
EDIT2: Cables have arrived, they're some fine piece of hardware. But the phone still refuses to charge at anything over ~5V and 1.45A. I've also ran another set of tests with a QC3.0 compliant car charger, to no avail - still charges at ~5V and 1.45A. I'm starting to believe that it's some problem with either the phone itself or the ROM/firmware.
I am using xiaomi quick charger and it shows 2870mah charging current at early stages of charging. Charging current was slowly decreased when battery percentage increased. is after 90% it shows below 1000mah and below. I am using ampere app from play store.
Hi Guys,
I have a thinkpad which has regular USB and also a fast charge USB port. They have worked fine in the past on other phones and I used to see at least 1 amp charge rates. (on the fast charge port)
Using either port on the 20 X I only get about 200 ma charging rates?
I'm using "Ampere" to get the charging rates, it is definitely charging slower than normal...
Have you guys noticed this?
Also of note, It charges really slow from my car as well. On the hour drive home the phone only went up 4%. (This is a VW using android auto)
I think all bets are off when your using 3rd party chargers. I think Huawei might have some official accessories that you may need to buy.

I have a bunch of phones and every single one of them charges at normal charging rates off my laptop and in my car, this is pretty strange...
Huawei uses a completely different setup from QC 3 from charger to cable . How does it charge with the supplied charger and cable that you received with your phone? If you buy extra chargers for home or car make sure they say they do Huawei "Supercharge". They are a little hard to find but they are out there. Make sure the USB cable is rated for 5a(amps)

I haven't even used the included charger and cable, but plugged in at the house I do see 2 amp charge rates which is great.
The downside is that in the car with android auto I can't really plug it into anything other than the car's USB and that give me a really slow trickle charge. This is where a bulk of my charging occurs since I drive for work so much. Basically I have never charged my other phones outside of the car, I just use android auto all the time and the batteries are always topped off. So not being able to charge from car or laptop is not a deal breaker at all, but it certainly means I need to start carry a charging cube around everywhere.
Just seems odd for such an expensive flagship phone to not charge correctly via USB like every other phone I have ever had.
Try the supplied charger and cable just to make sure you do not have a defective phone. When you plug in the cable to charge watch your screen. It should show your battery percentage and a short lighting bolt. Then in just a second it should change to a long lighting bolt and say super charging. If it does that you know your phone is charging correctly. Take your Huawei supplied cable and use it on your laptop and car and see if that doesn't increase your chances speeds.

I gave the original cable a shot and it still basically charges at 200-250ma from my laptop. Very odd indeed. Not even seeing the normal 500ma that you would get on a regular USB port. (Tried both standard and high charge rate USB ports on my lenovo)
Anyone else seeing this behavior?
