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] OTG Cable stopped working on Galaxy Note 2

So I've had my OTG cables (eBay/Amazon) for quite some time now. A couple of days ago it just stopped working. I was using it to transfer files from thumb drive to/from the phone. My buddy has the exact phone I do Galaxy Note 2 and both cables I have work fine on his phone but not on mine? Phone detects that the OTG is inserted with the usual "USB Connector Connected" notification but when a USB memory stick is inserted it will not show the "USB MASS Storage" notification and I can't see the memory stick in file manager. Occasionally (1 in 20 tries) and after a reboot, it will see the stick and allow me to explore the contents. I have tried 2 different cables that used to work fine with my phone and several USB sticks that also used to work and still do work on my buddies phone.
All other functionality of the phone remains perfect as it is fairly new. Charging through USB works fine, transferring data from USB to PC also works fine. I have looked into the port with a magnifying glass and it is clean and shows no signs of debris or pocket lint and the cable has a good feel when it is inserted. Positive click.
I tried to do a restore factory settings today and still it's totally hit and miss with either OTG cable.
Any help would be greatly appreciated.

Wow 60 views and not one suggestion. Guess this must not be a common thing at all.

I just tried it and works fine for me. Maybe try a different rom or custom kernel and see if it works then...I really dont have any suggestions
Galaxy Note 2

You said you tried the cables on your buddies phone but have you tried different cables on your phone?
Also this might help you.
Its meant for the gs3 but i can confirm works great on my n2. I see the dev has updated the op and others are saying the same.

:silly: "Bonk on the head!" I just remembered that several weeks ago while using a 2-port cigarette lighter to charge my Note 2 and iPad at the same time resulted in a funny burning smell. I took apart this charger (Amazon) and it was fried and melted on inside and obviously was of questionable quality. I guess at the time I didn't think anything of it because both the iPad and GN2 work and charge and sync perfectly well.
I've ordered a replacement charging port. Looks dead simple to change and phone itself looks much easier to take apart than the iPhone was. I found a site that sells the OEM charge port. I picked up an extra headphone jack as well since they are cheap. Yesterday while phone was charging in car, it woke up several times with the sound indicating a charger had been plugged in even though the cable was already plugged in securely.
I have also purchased the OEM Samsung OTG USB cable that was available for the Galaxy S2. I realize that the GN2 micro USB port has 11 pins but from what I have read the extra pins are for MHL HDMI output and there is no 11 pin OTG cable in existence but the port on the GN2 is backward compatible with 5 pin USB OTG.

Fixed
Today I pulled the phone apart and fixed the charging port USB OTG problem. Both cables that I have now are in working state.
This repair was VERY easy and took about 15min. with proper tools.

Please let me know how you fixed it. I am facing this same issue for past 2 weeks. Is it a hardware problem?

OP said it was a hardware issue for him. OP said replacing the small pc board and ribbon cable with the Micro USB port on it fixed the issue for him. I have replaced the USB port on my wife's Note 2 in the past (for a different reason, that is stopped charging.) It is a relatively easy repair, if you have the correct tools. You have to take the phone completely apart to replace the board, so you will need the small plastic tool to separate the bezel, as well as a small screw driver. There are walk through videos available.
If you decide to try this, avoid buying a cheap part. I bought a replacement part for about $5.00 from an e-bay supplier, but the company sent me two of them, and neither one worked. I bought a good one from and would recommend ETradeSupply out of Texas. That link is for the exact part. You will also pay for shipping, but it will be a good part. You can also buy the tools you need there if you want.

My Note 8 won't charge, not sure if flex issues because it recognizes a otg cable

(Not a native english speaker, sorry for any bad writing) Good Afternoon, first post made in this forum and I'm very desperate to find out why my tablet is not charging, I have tryed with 2 different charges and 3 usb cables but nothing, but when i connect a OTG cable with or without a USB pendrive in it, this will be recognized so i'm not not sure what the problem may be.
It is the chargers?
The Micro USB cables?
Or the Power Source?
Plz help me. Thank you.
Edit: Forgot to add, it will occasionally after several Hours to start charging back, but if i move it just a little bit it will stop charging.

This is your problem: loose USB charging port. Search Ebay for this part, may be cheaper if from China
Be aware that a defective USB port can read data but not charging or vice versa.

Replace this one is easy, just need taking the back cover off, remove two screws from this USB flex FPCB. Make sure search YouTube how to open the rear cover. Open the wrong way, you'll permanent damage it. Don't ever use metal prying tool to open the case.
This one is just an example:

Problem with charging plug

I've had my G3 for approximately 8 months, and I've been using it normally, wihout any kind of abuse, and using the cord that came with it to charge the battery. Yet, a very annoying problem has surfaced : the plug releases itself very easily as of late. Just slightly moving the phone when charging disconnects the plug. I checked the connectors on the phone and on the cable, and I could not find any kind of debris that would prevent a good connection. Has anybody else had this very annoying problem ?

i have a similar problem, not the cable unplug itself but the cable sometimes have to be on diferent position to plug suceful in the phone!
one thing you can do without have trouble is to buy a wireless charger (if your phone supports it in NFC antenna) and charge the phone with that! OR if you are in guarantee time you can send it to there and see what the technians says to you.

I would suggest two things... Start with blowing out any dust/crud stuck in the charging jack on the bottom of the phone. If still not charging properly, replace your charging cable with a new Samsung cable meant for the phone. I'm not 100% sure on our Note 5, but previously it takes an original Samsung cable to be sure you get proper (and fast) charging. If you do both of those things and it still doesn't charge properly, there might be damage to the charger port.

This happened to my Note 5 as well. Using a new usb cord works temporarily, but always goes back to not being able to fast charge eventually.
The fix I did and works, use a small instrument (tweezers, knife, etc.) and carefully bend the usb pin up (towards the screen) a little bit. Fixed mine completely, now my Note 5 fast charges 100% of the time, links to my desktop, and whatever else I connect it too.
