Anyone else have issues charging via computer USB?

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.

Nexus does not charge (through wireless charging) when powered on

Hi all,
I hope someone can shed a light on this matter.
I bought a Samsung Wireless Charging pad a while ago, hoping to use with my Nexus 5 and my Nexus 7 2013.
However, even tho it works fine with my Nexus 5, it doesn't seem to charge my Nexus 7 when it's powered on (no notification). But it seems to charge it when powered off (dim battery display saying that it's charging).
the rate is about 25% / 30% each hour, so I end up switching it off and leaving it overnight.
Since it's a mini pad, it crossed my mind that doesn't have enough output to charge it while on ( ? ) ? Or the power is the same on most Wireless Chargers?
Keep in mind it does charge my nexus 5, either on or off. It does charge my nexus 7, but only when it's off.
Someone can explain this?
Thanks a lot for your attention and any help.
Cheers!

You need to check the output rating to see what it is supposed to be outputting, and post it back here.

I couldn't get the output rating from the device itself, I only got Input (5.3V ---- 2.0A),
But I found it using the model ID,
https://www.mobilesupplies.nl/samsung-qi-wireless-s-charger-pad-blauw-ep-pg900ile.html
I got 1A / 1000mAh.
@SwoRNLeaDejZ, can you help me?

Alright, so the 1A output is MORE than enough to charge efficiently (I was nervous you might have a 500 mAh device, which for my S4, doesn't seem like a strong enough current). I would suggest using a different outlet, different USB cable, etc. to truly rule out anything else that might be causing the issue.

I did, besides using different USB cables, tried different sockets, but nothing seems to solve it.
I though it could be relared to the fact it's a "mini" pad instead of a normal sized one? Although it does charge when the tablet is off, so I haven't got an idea of what could cause this. I'm really in the dark about why this thing doesn't charge when powered on.
Thanks for your reply mate
PS - Even tho there's no indication of the tablet charging (the battery icon doesn't charge, no notification, the energy is still consumed) the pad does have a green light tho. So the charger says it's charging but there's no sign of it on the tablet.

Crossed my mind too, if I haven't tried official factory images and a bunch of roms :b
Is there any known app to determine the voltage input? If the battery is receiving any charge?

[ALERT] TYPE-C PORT and TWO accessories FRIED

So I was charging my phone like usual. And I was slightly aware that there was a compatibility issue between QC 3.0 and Type-C.
HOWEVER, tonight at about 12amish GMT. I kept smelling a burning smell... Which I thought it was my cat. but then when I decided to charge my phone using my Lumia 950 XL charger. I discovered the port had been burnt, and the cape and phone where burning ****ing hot! I felt the type-c plug from the charge against my top-lip and I got burnt...
I'm writing this a bit panic-y as I want everyone to just know TO BE CAREFUL. I'm not sure what exactly caused this as I have looked after the phone as if its my baby. Always case and a screen protector. I have a feeling this is down to compatibility!?
Anyone with similar issues, suggestions or such?

The Lumia is c to c right? If so, yeah there were lots of reported issues where people used various c to c cables with a c brick (most were pixel or nexus chargers that I saw) that had the same issues you did. Think it ended up being that the 10 doesn't have the right safe checks in place to stop charging at 100%, and it just keeps trying to push 3 amps even when fully charged (could be wrong about that though)

mmm.. the phone was charging from almost nothing... I think I was charging it from about 20% using a zuk z1 cable plugged into my computer that was connected to a usb 3.0 port. the cable is 3.0 standard and the phone is 3.1 if I rememeber

ive just added images into the original post

You don't Push Amps, you pull em, you Push Voltage.
The phone decides how much amps it wants to draw.
More likely missing cables inside the cable or bad quality Connector.
Was it an original Microsoft Cable from the 950 or bought afterwards?
P.S can't see the pictures. Just my bad Internet?

UPDATE: ok so, I've taken it back to the place I brought it from and they sent it to the repair centre (carphone warehouse). They've turned round and said tis water damage but I disagree as I do not like to keep my gadgets in places that are potential for issues. Will be taking it up with the shop. failing that, Trading Standards.
CAN SOMEONE HELP ME; does water corrosion look similar to that of corrosion caused by excessive current or connection shorting?

I had a ps4 controller do the same thing. it was cause by the cable was not 100% plugged into the controller port. it was still able to charge a bit but after awhile I noticed a burning smell... same results

By any chance green oxidation would indicate electrical corrosion from shorting of the contacts?

QC3.0 cannot exists as TypeC output, also the standard is not supported by USB consortium which developed USB Power Delivery instead.
Benson Leung warned people, that type c to type c charging should be avoided.
Even HTC10 does not follow the official usb specification and uses QC so best any user can do, i using legacy USB type A to type c cable and using charger with USB A output port. Also all cables must have 56k ohm resistor, cheap one come with 11k resistor and could damage power charger or the device. Check Bensons google+, he even linked to Tronsmart chargers which were out of specification and should be avoided.

Yeh, I became aware of this when the QC3.0 was released. Though, my assumption was because I'm connecting between usb type-c to the phones type-c it wouldn't charge off the QC3.0 standard.
Initially, I was using the Nokia type-C charger which came with my Lumia 950XL. It charges at 15 Watts (5V, 3.0A). I had used this the majority of the time and hadn't gone wrong. Sometimes I'd use a portable battery charge which charged at a generic 5V 2A AND a Samsung nexus 10 charger which was a usb female and charged a the same rate.
I would've assumed (also judging from the new releases by QUALCOMM) that QC3.0 phones would either charge of USB standard OR take advantage of QC. I've never used type-c to type-c charging only because I never had the capability. There is a slider in the settings menu to use USB3.1 standard but again, never used it. always done this through a usb3.0 to usb type-c cable.

HTC10 charges normaly from any standard legacy USB port like your old HTC M7 usb wall charger or notebook usb ports. QC3.0 uses data lines in usb cable to provide power and this method is not approved by the USB consortium, thats why you can not also communicate with your phone in QC3.0 mode, because there is no free lines for data left. You can either fast charge, or switch to standard usb mode and transfer files without QC3.0.
USB TypeC standard forbids strictly manouvers over the cable like QC does. For this, the newest Chromebooks and Nexus uses approved USB Power Delivery.
The "problem" was, that Qualcomm is also part of research and development of USB Power Delivery but yet, they in the same time were developing QC3.0. Was it for pure marketing purpose or to fill the gap between USB PD going live, we can not tell.
The only way now to end this confusion is to wait for Qualcomm to switch for USB PD as a successor of QC3.0 because there is really no point of two competing charging standards which one is spec certified and the other is not.

so would this mean I will need to set my phone to file transfer mode if I want to charge from USB?
Also, for reference, is there a way to disable quick charge 3.0 (which I assume may be present in the build.prop file OR am I thinking more noob like)

No, you must understand how usb and QC3 works. I will try to explain it as simply as I can.
Legacy USB have 4 cables inside, two for data transfer, one for curent and one for ground.
If you plug your phone to the usb in notebook, you can charge and transfer data in the same time.
What QC3.0 does, it is using the data paths for providing additional power, so when you plug it to your QC3 charger, it uses all the data routes/cables in USB only for additional and faster charging, so the data connection is blocked in this mode.

Ok, just came back from Carphone Warehouse. It looks as if the phone has corroded more during the time I've given it to them and the time its taken for it too come back.
The colour of the corrosion was of a greenish hue.

I'm awar eof this, but my question is if it can be disabled on the phone or not.

Never heard of disabling QC. I do not think that HTC will provide any tool to disable built in chipset feature.

Does anyone here use thunderbolt?

I plugged in my phone via my thunderbolt slot with USB Type-C and it says "Charging slowly". Is there a new type of USB C I need? (I got this type C cable in 2015). However, back when I had my nexus 5x, it would say "Fast charging". So I'm a bit confused here...
Is this normal?

The Nexus and the 5T have different power delivery specs. I would consider this normal.

Alright thanks!
I had gone ahead and plugged in the cable that came with the phone in my pc, now it says charging (not slowly) anymore. However, I want fast charging. I'd have to assume I need to buy USB C - USB C with a specific speed?
I'll look into it. Thanks for your help!

No, that means that the oneplus 5t won't fast charge from anything other than its charger due to different charging protocols. Changing the cable won't make this better.

Thing is, I am using the cable that was provided with a usb 3.1 slot. Even when placing it in a 3.0 slot, it doesn't say "Fast charging" but just "Charging". Unless that's now how it works in the one plus 5t. I come from the nexus phones so I'm just assuming everything as I am new to this specific brand.
The phone itself is lovely! It's a really good, solid phone and I will never go back to the nexus phones ever again. I cannot wait for custom roms to come out with Oreo!
EDIT: Aah, problem solved. Turns out you need to use the Dash power adapter. Now it's charging extremely fast! Thank you so much for you help!

The phone's usb C port is USB 2.0 spec compliant, so the USB 3 higher power delivery sadly won't work. It's good that you like the phone.

What to do if my phone does not charge using airline USB?

In my last two international flights (United and Norwegian), I noticed that my OP3 doesn't charge when plugged into in flight entertainment system USB. When plugged in the cable, I also tried Ampere to see charging levels but it indicates the phone is not charging.
During flights, after noticing the issue, I tried the following when plugging the cable, with no luck:
turning the phone completely off/shutdown
tried using two different cables (one standard and the other DASH), both failed but otherwise work fine if used in any other USB port (e.g., workstation).
tried different USB ports (where others were charging their devices).
I also asked others to try charge their phones on the same port, two different phones charged fine (one was iPhone and other Samsung).
I am running official OOS 5.0.1 with blu_spark kernel. The phone used to charge fine in flight few months ago, so not sure if it's a software issue...
Any thoughts or solutions?

I'm sure the USB port doesn't supply enough amperage to charge the phone. It's probably just like my truck's radio USB port, it will not charge my 3T.

if that is indeed the case, then, on a technical note, how much amperage OP3 needs?
(I am asking because, as I mentioned, on the same port iPhone 7 and Galaxy S8 were charging...)
