USB not powerful enough to charge?

Anyone else having this problem. When I have my TMOUS TP2 hooked up to USB I keep getting told it's not getting enough power to charge.

Interesting. Is the USB plugged into a USB hub or straight into a computer? I can charge mine via USB when its straight into the computer. I'll try with hub a second to see if there is a difference.
Edit-
No, I cant. When plugged into a 4-port USB hub, I also cannot charge. I'm using some generic nonsense hub, dunno if a higher quality one (or one that also plugs into the wall for juice) might make a difference

Yes!
Many laptops are not powerful enough to charge the TP2. Also many hubs will divide the power between the ports.
A standard USB port will give you about 1A and the above mentioned gives you typically less than 1/2A.
Putting TP2 in standby will help if on a weak port, but that makes no sense, cause then you can use the charger.

It's directly in to my PC.. weird.

I got the "not enough power" USB warning when plugged into my laptop...but not right away -- it had been plugged in for 30-60 minutes or so.
I have not received that warning when plugged into the USB port of a full-power-desktop PC, even when plugged in for hours.
I try to remember to bring the ac adapter that came with my TP2 when I'm going to be away from home for a while so I don't have to depend on USB-power from a computer.

I charged off a 0.5A power source (the most you'll get out of a standard USB port), but the device was turned off. Took about 3.5 hours to fully charge it.
Did you have anything like wifi, gps, etc turned on at the time?

how much power is left on the phone? IIRC, if its too low, your phone will not charge through USB & you need the AC adapter.

There are "powered" and "unpowered" USB ports. The "unpowered" ones just basically carry enough current to carry signals, but not actually power a device. The "powered" ones carry enough current to charge a device.
Many laptops are "unpowered" ports, although I think that trend is changing. Most desktops I would assume are "powered".
I personally only power my phone on one of two official chargers I have, although if I'm in the car I'll use a third party adaptor there.
I don't know if the TP2 is any different than the Tilt in regards to charging, but I'd assume very similar.... Perhaps I'll have the TP2 soon, I've finally gotten ATT to let me have an early upgrade but haven't found the actual phone yet.

I have a 5v 1A car charger. When in the car if I am using Pocket Player, and my GPS program at the same time I will get the message that:
"there is not enough current to properly charge the device. Please should shut down unneeded programs." or something like that...
And sure enough, my phone will die if left like this. It won't charge, even though it shows that it is... curious.
Could it be the cable is not allowing enough current? I am using an older cable in the car, as I have my TP2 supplied cable on my computer....I am going to try swapping these 2 cables tomorrow and see what happens.

I've had my Sprint TP2 for 12 days now and experienced this problem once. I was plugged directly to my PC via the USB port. I believe my battery was at about 30% so I disconnected it and used the travel charger for awhile and plugged it back into the PC USB port. So far that's the only time it's happened.

Might be the cable!

Hello,
I had exactly the same problem and found out it WAS the USB cable - the one used couldn't offer more than 300mA to the phone, even if connected to orriginal HTC AC adapter. After changing the cable, the 1A car charger gives the same mA as the AC adapter (checked with nuePower - http://www.nuerom.com/BlogEngine/page/nuePowernueBattery.aspx)

Thanks for the info.. I haven't driven anywhere since I posted that! I will be in the next day or so... glad to know the answer is simple.
I too, just downloaded the NuePower program. Will be installing this as well. Did you by chance have the chainfire 1% battery cab installed? If so, did you unistall it first? Wondering if there will be a conflict between the 2.

Hi,
Yes, I have chainfire's cab, I didn't uninstall it before installing NuePower (btw, I have tried once to uninstall it and after a soft reset, the 1% info was still there). the only bug I saw was when pressing the OK button in NuePower - sometimes phone hungs or runs very very slowly. Best is to use it only to test the cables and uninstall it. and don't press OK button, just minimize it with End Key or do a soft reset if handy.

Mine does the same thing lol
I get the same thing, i think they should make these devices use even more power.

Don't know if will help, but last night I was in my car using Live Search for GPS purposes. The battery was low on the phone, so I plugged it in. The phone told me that the source was not strong enough to charge the phone and to try shutting down some apps. I assumed that it was because the GPS was still active, although I really don't know because I didn't bother testing that theory, as I was just around the corner from my house. (No jokes about using the GPS to get home, please. )
Anyway, when I got home, I plugged into my laptop (which was running on AC power) using the cable that came with my XV6800. Note that the cable is always connected to my laptop via a cheap USB hub. I experienced no problems.

[Q] USB Wall-Socket from ThinkGeek. Will it work with my GNex?

I apologize if this is a dumb question, but I'm not exactly an electrical engineer. I was looking at buying one of these for my room: http://www.thinkgeek.com/gadgets/travelpower/e81a/ and it says it outputs at 2 amps. i notice the stock Samsung charger is 1 amp. Will I be doing any harm to my phone by using the wall outlet vs. my stock charger? Or will it detect it as a USB charger, charging it at a slower rate?

Ya it'll be fine, it says UP TO 2.1amps.
Also it says it charges all mobile phones that accept USB power.

yes it will work. I have a few of these installed in my house. Your device will only pull the amount of amps that it needs. The voltage is what you have to look out for...

it will work, but it is not up to the 2011 nec code as it doesn't have tamper resistant shutters, I would recommend this instead.
http://www.amazon.com/Cooper-Wiring-Devices-TR7740W-K-Combination/dp/B007NC5GI4
It works the same, is up to the latest electrical code, is cheaper and will work with a standard wallplate.

Thanks for the input everyone, I think i'm gonna spring for one (may not be the Thinkgeek one though, as the one cade80 posted and a few other's I've found are cheaper) at some point, just to cut some clutter from my bedroom a bit.

Although you lose 1 standard plug, the big plus is being able to use normal faceplates with it.

Be aware, this Cooper one is only 0.7A ... it won't charge an iPad 3 and is slower to charge then the OEM Samsung charger.

Good eye on that, depending on your needs this may outweigh the being up to current electrical codes.

most third party charger will not charge you samsung smartphone at full power.
to charge at full power you must shortcut middle pins.
"will not charge" - not correct, your phone reduce it

So I went ahead and decided to not spring for the ThinkGeek Charger, and instead bought one of these: http://www.lowes.com/pd_369050-6337...&pl=1&currentURL=/pl__0__s?Ntt=usb&facetInfo= and just put it in a standard plug to test it to make sure it worked. Well I plugged it in and the first thing I noticed was the GNex was taking a while to recognize the plug. Finally it started Charging (USB Though) which was OK with me. Well last night I plugged it in via my Samsung Charger to a standard power strip because I hadn't gotten around to installing the RCA plate yet. Well I woke up this morning and it was on like 50% power and wasn't charging. So I was like WTF. So I brought it into work with me this morning, and now when I plug the stock Samsung charger with the stock samsung cable into the wall, no charge. I tried plugging it in to my computer, and it eventually makes connection with the computer (it's not instant like It used to be) and Android File Transfer starts, but says it can't connect to the phone. Then it charges for a few minutes, up about 1%, then stops charging. So my question is, when I plugged in my phone to the RCA charger last night, did it fry my phone? Or is my charge cable maybe bad now? I haven't tried another cable yet (everyone at work is an iPhone user and doesn't have a Micro-USB cable lying around) but I'm going to try that and hope it works. If it's not the cable, is it possible that the phone itself got damaged? If so, how could I go about removing root and wiping it to take it into the VZW store for replacement without USB to the computer?

Another new development. I plugged it into a Windows Box (I was using a Mac) and when I plug it in, it says "This Device can perform faster" and talks about plugging it into a USB 2.0 port. I'm using a 2009 Macbook Pro, it has USB 2.0. It won't mount the disk either. So i'm really beginning to wonder if the USB cable is fried.

Turns out it was a bad USB cable. Went to Best Buy and bought a generic cable and it now charges and hooks up to the computer just fine. My ADB doesn't seem to be working though for some reason, on Mac or PC...

Ok, everything is working now. ADB wasn't working because of a conflict with EasyTether on my Mac. Thanks everyone for the suggestions but I've decided to just stick with what I have now (power strip) and not deal with it.

some electrical codes are good some are only updated so a manufacturer can score some more money from sales
Like when the addition of ark fault breakers

May I recommend you return the Best Buy cable and go to monoprice.com?
I bought five cables from them that are 6 foot long. They work terrific and are higher quality looking than what you get from Best Buy.

[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.

Power supply

Although I have two official razer branded chargers which are fine I'm trying to reduce the amount in carrying around and for day to day usage the phones 4000mah battery has not dropped below 15% yet.
I'm planning a trip soon so wanting to cut down on what I am carrying however USB C is now my main standard so you would assume carrying a single razer wall plug with usb is enough.
Currently using
Razer Phone - USBC
Razer Headphones - USB To Micro USB
Razer Nabu - USB to non standard
A RavPower power bank 26800mah with USBC and power delivery.
My Nintendo Switch
The standard razer plug works to charge all the above however the non USBC devices will need to be in the power bank so wanted something as good but with a standard usb port too. Which is why I saw the below and wondered if it was any good to charge the phone as it supports outputs the phone charger doesn't. I don't know much about this so wanted to check it wouldn't damage my phone.
https://www.amazon.co.uk/Charger-RA...tDescription_secondary_view_div_1515491595656

it will not charge as quickly because its a different quick charge tech than Qualcomm's QC 4+ thats on the Razer. if you want to have both ports then its fine. otherwise invest in a cheap usb-c to usb adapter and use existing plugs:

Thanks for letting m know i wont bother getting it then as the Razer charger charges everything i carry and the non usbc stuff will just have to be powered by my power bank.
Sorry if mods didnt see this related to the phone but i was trying to figure out the phones power options with some reason to why i didnt just want to use the supplied power block.

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...)
