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.
Sorry if this is a duplicate thread, I searched quite a bit for a solution but only found stuff for the TP, not the TP2.
Ok, so I know with the original TP you could charge it from a computer, but it was not as fast as a wall charger unless you had the fix that allowed it to charger faster on the computer.
Well on my TP2, it really won't charge the phone, and if I am using something like wifi router that uses a lot of power, it will actually lose power while charging off my computer...
Is there a fix to bypass this so I can have my phone plugged into my computer and charge it???
make sure in your battery settings the box that says "when device is turned on, do not charge the battery when connected to the PC" is unchecked. meaning an empty box. if its checked off, uncheck it. also, this might help, when plugged up to ur computer, cut ur backlight all the way down or low. the phone will use less battery that way and will charge faster when hooked up. either way though, charging thru a pc is trickle charging, meaning its gonna b slower than wall charger anyways. i havent came across the fix u mentioned for the TP.
trickle charging is when battery is fully charged and is still pluged on charger, then charging change to trickle power charge, around 20mA+actual request of the phone. this way if you have phone/any electronic in general on charger for a month, it's still kept fully charged.
---
htc have two modes of charging slow 500mA and fast 1A (1000mA)
to say to the phone that charger is fast, you need to have one pin on mini-USB connected to ground. this pin is unused by mini-usb specifications but htc is using it for this trigger.
---
cut open mini usb connector on usb to mini usb cable and wire the unused PIN to power ground (get pinouts pics or use multimeter!!!!! don't guess try it)
then you still facing another problem, USB is strictly specified to not exceed 500mA (with 10% toleration) no trick to get more then this from one usb. some computers are not so precise with rules though and could give slightly over 550mA
to get 1A you need to use two usb ports in parallel. like some china made usb harddrives enclosures
get an additional USB connector and add it to your cable.
NOTE: DON'T CONNECT DATA LINES ON THIS SECOND CONNECTOR!!!!!
data = inner 2 pins
power = outer 2 pins
* you can get an USB extension cable, wire 2 power lines out of it, connect to your usb - miniusb cable... this way you still can use the other usb for other device
NOTE: this is not a standard though accepted solution. I haven't saw or heard of any burned computers cos of this but wouldn't be surprised to see one.
anyway if I had that need, I would go for it
when making this cable, be very sure 5v wire is not touching data lines!!! Test it properly before plugging to PC! I have brand new laptop now, the old one is lying with DEAD usb host below table just because I believed there have to be protection against this. There IS NOT.
NOTE: NEVER LAUGH ON MY PAINTINGS!!
Or you can buy one for $4
http://eshop.macsales.com/item/Othe...medium=shoppingengine&utm_campaign=googlebase
actually NOT.
without grounding the special pin on mini USB side of the cable, mobile would charge by 500mA no matter if you put 100A charger in. or paralleling 20 USBs
Wow...I'm pretty tech savy but that was a bit confusing...so I get the gist of that, but how is it that all it takes is plugging the usb chord into the htc ac power supply will fix that? why isn't it required for all that jazz of rewiring crap on the ac adapter as well, since it comes from the same usb chord...?
eh, have mercy with that english slang we are mostly not englishers here
What you meant was, why htc AC (wall) charger charges on hi power without those tricks?
Because the connection is already made there.
That's not a hidden trick anyway. Not even trick. It's a standart feature.
HTC is, not like other manufacturers, sticking to specs and mobile would not demand more then 500mA from standart usb connection.
usb is defined to be max 500mA
if you want a connector which is based on standart (htc's usb-hub can use usb cables), and you want a fast charging without violating standarts than this was the best resolution, to use pin which is generaly unused to trigger-detect 1A charger.
But as htc didn't made computer fast-charge cables. A serious company will not release such a cable. Connecting power from two usb hosts together - I feel pain by doing it, but it proved computer stabilizators don't mind it and though I don't think it's giving really double, it's giving more then 500mA.
But here you have to "imitate" original htc AC charger by shortwiring that trigger pin the way as it is there.
hope this was your question about.
Just final note in red when making this cable, be very sure 5v wire is not touching data lines!!! Test it properly before plugging to PC! I have brand new laptop now, the old one is lying with DEAD usb host below table just because I believed there have to be protection against this. There IS NOT.
My phone is nokia X1-01 basic phone
It comes with AC-3 charger
I live in a home and office where power plugs are very rare to find but lot of usb ports. Those days i use smart phones they are easily chargeable as they had micro usb. Can i buy the below cable to charge my phone? I know it is compatible with my phone but my worries are will it reduce the life time of phone or battery? I don't worry when i charge my older phones because they had micro usb that as every one know always same voltage and amp.
http://www.ebay.com/itm/USB-to-2mm-...195162?pt=PDA_Accessories&hash=item4155abc6da
I have three phones with microusb
I have three phones with microsub, and i charge all with diferents microsub cable, sometimes with the microsube of my digital camera. My phones are lg,sony,and one chinnesse phone. I don't see problems with the microusb and don't feel something strange in the life time of the battery.
Don't worry about battery life. Perhaps it will charge a little bit slower than with a real power adapter, but there's most likely no difference at all.

cable should be find. The only time I had a problem was using the wrong charging module which crapped my battery to only charging half way
Today I picked up and installed two combo 120v/USB wall outlets so I can get rid of all the wall warts I currently have. The USB ports charge everything (tablet, HTC phone, Bluetooth) but the two galaxy S4's I have. Has anyone used one of the outlets before? Any ideas on why they will not charge the S4's?
The Specs for the USB side of the outlet is.
Switching Frequency Typical 140 kHz
Output Voltage Nominal 5V (+/- 10%)
Protection Current Limiting and Thermal Shutdown Protection
Output Current Constant Current Maximum 2.1A
The outlet is a Commercial Spec Grade Combination USB Charger made by Cooper Industries
Part number is TR7745 if anyone wants to look it up for any reason.
Thank you in advance for your help.
change usb cables
Try changing to a different USB cable. It's weird how often this is the problem.
What does it do when you plug it in? Does it do anything at all? Does it even act like it's connected? Does it TRY and charge but just can't keep up? I have ones by Leviton that work fine with my S4 and my fiancees iPhone/iPad.
EDIT: I just noticed if you look at the reviews on Amazon HERE it seems multiple people have had problems with the S4 and this model. One thing I noticed with most that I looked at before buying mine was that the listed current was shared between the ports, whereas the Leviton version has one port that's 2.1 amps and one that's 1 amp independent of each other. This one might be 2.1 amps shared, so anything else plugged in might not work out.

I'm having the same problem. It's listed as "dual 2.1A". The first second I plug it in it flashes the charging indicator, then it goes off. No charging happening whatsoever.

Did you ever have any luck with the S4 problem? Does it make a difference which side you plug the USB cable into?

Try using a different usb cable from phone to charger,
be sure both ends have a snug fit and it should work.
I have one which is similar to yours.
Since it puts out 2.1ma just like the stock S4 wall charger
it should charge just as fast.
Good luck!

Unfortunately no. I didn't mention before that I'm an EE, however, none of the troubleshooting steps I could think of had any effect. :crying:
Can use A Cooper USB Electric Outlet with S3 and S4
I saw this thread while trying to solve this very issue. I have the Cooper USB outlet and installed it thinking it would charge my phone and my wifes. It would charge her S3, but not my S3. She has the LTE version (SGH-I747) and I have the HSPA version (GT-I9300). Well I thought it would not charge my S3. After playing with it for a few minutes, I could get the charge light on the outlet to blink. No charging was happening as the charge light on the outlet would just blink and then stay off. On my wifes S3 I could plug it in it would start charging instantly.
After playing with my S3 and the cord (The same cord used for my wifes S3 as I had already tried numerous cords) I found I could slowly insert the micro usb end into my S3 and it would start charging. It was tricky, but after 30 minutes of wasted time, I got it to charge. I would have to ever so slowly plug it in, either at a sideways angle or at a slightly elevated angle. This was regardless of the usb cord used.
However my S3 died and I got an S4. Naturally my S4 would not charge just by plugging it in, but I tried the "slow insert" method, on both the micro USB side and the outlet side and both worked.
I am thinking there is some kind of tolerance issue surrounding the electrical connections. Sliding the USB connector in slowly at the outlet side, I beleive, would ground the connection first and then allow for charging, but this is where my knowledge of electricity starts to bad. That said it is possible to use the charge, but it is not plug and play.
I just picked up a couple of these for the kitchen to alleviate the eyesore of the wall warts and I can also confirm it charges everything I have thrown at it except my S4 (jfltezvw) =( I quickly found this post after googling it. I am currently doing some work on the phone now but I will attempt the super technical "plug it in slowly" later and see if it works =)
Has anyone had any luck with other brands? I find this REALLY odd.
just installed this same outlet, and sure enough it charges everything except the S4..."slow insert" doesn't seem to work...does anybody know of any other solutions besides not using it?
wall charger option
I also have one of these outlet/usb from cooper that will not work with my s4.
Has anyone tried to use a DUAL POWER micro USB cord (like the ones that comes with the portable hard drives) to see if that would do the trick?
unfortunately, I do not have one of these cables, or I would try it myself.
Here's what I am thinking is happening...
The S4 is equipped with a smart charger that can trickle charge after a complete charge cycle.
When first connected, the s4 starts a trickle charge while it tests the battery for the charge cycle.
The cooper is equipped with a current limiter that shares power between the two outlets.
The cooper unit sees the trickle charge, and switches to a lower current setting for the slot with the s4 plugged in. reserving current for the empty outlet.
The s4 then tries to engage a fast charge, but cant due to the lack of current, and shuts down the charge circuit.
If a dual usb cord to micro usb cable was used, both outlets would be tied to the s4, and full power would be available to the s4 at all times.
Of course, without a cable myself, this is almost all conjecture on my part, and I could be just blowing smoke up my own arse, huh?
LoVoltage
EDIT: Of course, remember that the cable you use has to have the D+ jumper to signify the 2.1 amp availability. If you don't, the cable won't work. (Most dual port usb cables have this jumper already. so does the OEM samsung cable)
Just installed one of these tonight. Specifically the Cooper TR7745/TR8245 15A/125V
I can charge my Note 2 (SGH-I317), Nexus 7 wifi, but not an Samsung Galaxy S4 (SGH-I337). Kinda weird.
I've had my G4 since almost launch day and within weeks the supplied USB cable stopped charging the phone. I thought it was a cable problem, but it worked fine with other devices.
I tried other cables with the G4 and these still charged it so I thought nothing more of it until charging degraded with every USB cable I own to where the phone would only charge 20-30% during an overnight charge and the phone would frequently not recognise it was plugged in at all. I contacted LG who did a repair under warranty and all was fine.
I've now had the repaired phone back for about 3 weeks and the same problems are starting up again and it's only a matter of time until I am forced to return again for a repair.
Is anyone else having similar problems? I thought I may have just had an unlucky manufacturing problem, and the LG reps confirmed that to repair my phone they basically replace all the internal circuit boards and components rather than just replacing the individual component that is faulty (in this case the USB/charging port)
Basic debugging includes asking stupid questions, so please forgive but still answer any of those
Are you using a different charger? If so, check if that one is within specifications and if you do send in for repair again, use a different charger.
Are you propping up the device at an odd/weird angle or in a dock of some sort with the cable attached?
(As they replaced the entire print, it's probably not this, just the USB-micro port bent or broken.)
You could double check the wall outlets being used, there might be some kind of electrical problem there.
Either using all kinds of fancy electical testing gadgets, or stick a USB light into the hub or charger, does it flicker?
When sending it back for repairs, did they check the stock charger as well?
Hopefully these questions help you find any logical or plausible cause.

Hi FreezyExp,
1. I am using the standard charger that came with the phone, but this has not been repaired/replaced. I have tried other chargers too, but all the same issue.
2. No weird propping up or anything like that. If I hold my phone while it is plugged in it is constantly vibrating as the charger connects and disconnects, and if I place it on the desk to charge I have to ensure that I have at least 3-4" of cabe "on the desk" to give it enough support to make the connection.
3. Wall connection is fine and I have tried it with a range of outlets around the home, both with extension sockets used and plugged directly into the wall and there is no different. No flickering light when using a USB light either.
4. When I sent it back all they asked me to return was the main section of the handset - so no battery or rear cover, no cables or chargers etc
It does seem to be the same issue as last time, a USB connection becoming loose from the main motherboard, but it seems weird that I have had the same issue twice in the space of 4-5 months.
I've been having some sort of problem with my G4 usb port. If I plug it in to a computer, it will lose connection and get a connection again if I barely touch the end of the cord at the phone end. I've tried many different cords and different usb ports on my computer, but it still has problems.
I can't fast charge, either. When I plug it in to fast charge, it actually starts discharging even faster. I've had some extreme battery life problems, too. It drained from 100-36 the other night with everything disabled, and it's been doing that kind of thing a lot lately. I'm guessing that the charging port is what's messing up my battery life because it won't charge correctly.
Never dropped it or anything.
I got my G4 on January 24 and my USB port has also failed. I am getting a replacement from Verizon, but am concerned that a six month old phone has this issue.
I also own a G4 H815. A while ago the phone started not receiving any charge from the cable and I would have to prop it up from right under the cable's micro usb end. Thought it was because it was bent inside the port and not making connection with the cable so I had the port replaced. Now I'm experiencing the same problem and I think it might be the cable that's already gone kaput and is effing up the port itself. I took the phone to the same place to get the port replaced again and bought new cables (I lost both the original adapter and the cable, which were charging slow anyway. Now using a 2A Asus adapter which works great) and when I asked the guy at the repair shop, he says it's a chronic issue with G4 devices. I don't really understand how it would happen twice in just a few months even with a new charger port. What should I make of this? Did they replace my port with an already faulty one, cahrged me full price and now trying to sell this bogus or am I really doomed with this phone?
