I can't understand why it is so slow to charge!
I tried also nuePower... but with no results.
The phone charge slow (in the same usb port where other htc phones charge quickly!)...
Do you have suggestions?
usb charging is just like that.. if you want it to charge faster, use the wall charger. although, from what i've heard, slow charging is better for the battery anyways.
yes but I usually use my tp as modem and happens that phone discharge quickly than what it charges!!! so after 3 hours phone is completely discharged!!!
This happens only with tp and not with touchHD neither with TytnII!
Incredible!
Although the voltage is the same on a PC USB port as on the wall charger, the amperage is much lower. Thus, the phone will charge significantly faster on the wall charger.
However...
I also use my TP as a modem, and I can leave it on the web indefinitely. If yours is running down, perhaps there's a different issue at play - if you don't have any power hungry apps running in the background you might just have a borked battery or USB port...

Just put your phone off... the charching goes much faster...

I tried just after hard reset without installing any application before.
I'm using Energy ROM and I'm quite sure ROM doesn't have any problem...
I do have the same problem with my Touch Diamond. When connected to my PC or even using my car charger, it will discharge completely after 2 or three hours of using, say, GPS and a few 3G connections to check traffic.
I can't use my Diamond as a modem for the same reason... I have flashed several roms and radios, nothing changed.

Check if the TP really charges! The unit switches off the charging mode when it gets too hot or better too warm. So e.g. when in use as a GPS in car typically mounted on the windshield, it gets too warm pretty easily as GPS is quite an energy hungry application and quick discharging also heats up the battery.

Cactus World
P.S. If you are using the TP in car and have aircon, then try to direct one of the cold air streams to the TP to keep it cool. That helps to prevent the switching off of charging mode.
Try tbattery
I use the Energy Rom and it has a utility called tbattery that can show you whether the phone is charging or not and at what rate. Would at least tell you what's happening in the phone. Also gives you the internal temperature of the phone. I've found anything higher than 41 degrees c causes the phone to go into a slower charge mode; it's possible that a higher temp could stop charging altogether - however it should still allow you to power the phone and not use the battery....
I can use phone as modem and still charge it via usb. maybe try a different rom?
I can do that, too ! The problem is the phone charges too slowly, so that the actual power consumption is higher than the charging...
I think that it depends on how you use your phone as an Internet source. I use wmwifirouter, and last time I plugged into ac, my batery still ran down. If your phone lasts 4 hours as a wifi router with no power and charging takes 5 hours, you are operating at a defecit.
I'm using 3G and Internet Connection Sharing through USB cable.
And my diamond charges completely in less than two hours using the wall charger.
Normal behavior, USB port doesn't have enough "juice" to charge it faster.
If you want a quick charge - use wall charger.
1) I can't use tethering through USB if I use the wall charger
2) I use tethering when i'm NOT near a wall power outlet, obviously
3) I don't want a "quick charge"... I just want the phone not to loose charge.
4) I have owned many WinMo devices and this is the first one that will not hold charge while connected to USB
Start -> Settings-> System tab -> Power
There will be a check box that says "When device is turned on, do not charge the battery when connected to the PC." Make sure it isn't checked.
That's the only thing I can think of right now. If I think of anything else, I'll post it.

Thanks for the hint, but it isn't checked.
I think it's just that the phone requires too much power
And it's getting very hot very fast, which will hinder proper charging, too.
I wonder if other modern HTC devices have the same overheating problem...
hello
sorry for pushing up the topic with no sloution but new question, but yesterday i get mad when after two hours of playing streamed music + being connected to wifi my TP battery died :/ Phone was connected to wall charger (oryginal from HTC) and still i was not enough. Damn it didnt happent ever to my blueangel/eten/hermes or any other earlyer device i had. Really im starting to be angry on my latest choice of this phone i should have stay with kaiser
sorry for spelling mistakes but my English is more verbal than writable
so im rooted vanilla bean rom latest imo kernel so when im charging in my car my phone gets hot for some reason but not at home with the htc charger and cord or any other cord only my car charger it will go up from around 90f somthing to around 110f anyone else have this problem or is this a problem
Yep. Gets even hotter running GPS and charging.
makes sense to me that the phone would get hotter when using a car charger than a home one since the car charger is a "Rapid Charge" so more power is being injected in a shorter amount of time.
double post sorry
I didn't even think about it being a rapid charger that makes sense
power = current² * resistance (P = I² * R)
or
resistance = power / current² (R = P/ I²)
so the more power you're pulling into your phone from the source, the more heat (resistance) you're going to get
Your car is going to pull less current into your phone as well (because it's a 12V battery to 110V at home), so less current means more resistance, thus it will get hotter.
http://en.wikipedia.org/wiki/Ohm's_law
The amount of current that the phone pulls is determined by the phone itself. (it is far from a simple resistor). And the way the USB cable is wired.
Because it uses switching mode power supplies, the charge current to heat generation gets complicated.
On this phone, if the USB wires are tied to a PC or left alone, it charges at a low rate. It the USB wires are tied together, it knows it is on a high rate charger and pulls a good bit more current.
If you are not using the GPS and the display on bright, you may want to look for a low rate charger to help keep the heat down. If you are using the GPS continuously with the display on, you need a high rate charger just to keep the battery from going dead, because the bright display current can be more then the charger output.
BTW, the comment about 12V having less current the 110V is wrong for many reasons too. Again, switch mode power supplies, not resistors.
Hello all. I found some information that some of you may find useful, so I wanted to share.
If you are running a custom kernel, go download Current Widget from the market
https://market.android.com/details?id=com.manor.currentwidget&hl=en
Install it, add the widget to your screen, and plug in your phone. You should be getting 350-380mA, this is AC charging mode. If you are getting in the low 200's you have a charger or cable that is not bypassing the data+ and data- wires in your phone, this is called USB charging.
If it is showing 0mA, then your kernal is not supported and it will not work. You can still do the steps below and get the same results, you will just not be able to see the data visually. I am running Gummy2.0 and the widget works great.
Some chargers are built .. badly.. and rely on a specific cable that will bypass the D+ and D-. the problem is, that cable will not work for anything USB related, such as flashing roms.
If you are anything like me, you have a dozen USB cables laying around and just use the closet one you can find when you need to charge up. However, if you use a data cable with a wall charger that does not disable D+ and D- you will charge at the USB charging rate, which is much slower than when AC charging is enabled, and can be irritating when your phone drains more power than its getting from the charger, resulting in power loss. This happens often while using your phone as a wifi hotspot. In USB charging mode, you can potentially drain the battery faster than the charger can charge. This can be prevented by being in AC charging mode.
You can either dig around for cables and test them out with your charger to see if you can get up to the 380mA range, or you can solder the D+ and D- points together in your charger. I do not recommend the 2nd option unless you are failure with soldering on small IC circuit boards.
But if you are adventurous, the 2 center pins on the USB cable are D+ and D-. If you open up your charger you will see the backside of the USB port and notice the 4 solder points that connect to the USB plug side. Place a bead of solder between this 2 to short them together. This will allow the charger to be in "AC" mode and charge at the higher rate.
This will also work for USB plug car chargers and will allow your phone to continue to have a positive charge even while navigating (which as most people know, Navigating can still drain your battery even when its plugged in).
Hope this helps! Feel free to ask any questions, I will do my best to answer them.
-EDIT-
Make sure to set the update interval in Current Widget to 1, for 1 second updates, this will help when monitoring the charge current.
Let me test this out... I'll report back in a lil bit. Calibrating battery, can't charge. Later...
I'm using a 10' cable from Monoprice. I'm getting 373mA. I'll post on what I get using my car charger... but I'm getting pretty good battery life that I rarely have to charge it in the ride
Hello everyone, I just have a question in regards to USB fast charging for the Galaxy Nexus.
I'm about to install a JVC head unit in my car (model KD-R810) and it proclaims to have 500ma available for charging Apple devices. My fear from my research is this will not be enough power to charge my Nexus while using GPS, so I am looking into other methods.
What I am thinking to do is use a Sirius car charger that is no longer needed (that puts out 5v 2a charging capability) and use this to keep the phone charged.
Now my question is, if I have the data portion of the USB cable connected to the above mentioned car stereo head unit and the power portion of the USB cable connected to the Sirius charger, can anyone suggest any reason why this is not a good idea?
Also, will I need to trick my nexus into charging "AC" rather than "USB" even while connected to a USB charger that can supply 2a?
I've read articles about having to short the data lines on a USB to get it to charge in AC..?
I am wondering if doing something like this is needed? I currently have a rocketfish charger rated at 600ma that charges the nexus in "AC" mode, however I'm wondering if having 2a available using the Sirius charger will charge the phone that much faster, or if this is dangerous for some reason? I did read somewhere that the nexus will only draw as much power as needed and should be safe with higher rated chargers, however I wish to confirm before risking frying anything.
So my question is, if I wanted to use my Nexus with GPS and with my above mentioned JVC stereo as a storage place for music, would I benefit from using a hacked cable on a switch for example to be able to switch between GPS charging mode and "Data" mode for use with the head unit?
Perhaps a switch for the data portion of the USB to switch between going to the headunit and being shorted for fast charging?
Any guidance would be appreciated!
There is a kernel patch know as Fast-charging. It's implemented in Matr1x and air kernel i believe. This should do the trick.
Sorry i didn't see this before, don't know how i missed it. Here is the rundown:
-Data mode uses 500mA
-AC mode exceeds this, stock charger rated at 750mA
-Excess amperage should be limited by the Nexus S with no problem
-FastCharge forces AC mode, so the phone will attempt to draw the max current it can handle. NO DATA TRANSFER is available in this mode, so can't use it as a USB for your deck
Essentially, i would be using a kernel with FastCharge with the 2A charger and get the Nexus S to decode and output music through a 3.5mm jack to the AUX input on the deck. I hear it can get quite hot while charging and using GPS, so make sure to check it's heat every so often just in case. Decoding music will put practically no extra strain in comparison to everything else it'll be doing, it won't slow the charging by any noticable amount.
Heat can be a problem when using GPS and charging at a high current, my NS gets hot doing these two things at same time!
Try putting the device near a cold air flow inside the car.
hi, since i got the phone (2 month) i was very surprised because the fast charge, 1 game of lol was enough to get 60% or more, but since last 4 or 5 days, i have noticed that it does not longer charge like before, it used to need around 1 and a 20 min to charge all the battery, but now it takes around 2 hours, like using a normal charger. Thanks, and btw english is not my first language :silly:
Happened to me once, rebooted the phone and fast charging was working again.

fastcharge works only with screen off and no app opened (es. game/video/music/etc)
Also make sure you using good quality cable. Some weak ones can "block" quick charge. Best setup is just the stock one.

It still fast charges while in use... just won't be as fast since you're drawing power too. However, using the battery while charging at the same time makes the battery heat up very easily (true for most all devices even on normal 5V/1A chargers) so it is always recommended to keep your device in a state of minimal drain while charging.
I've had issues on past phones where sync/charge cables (stock ones even) get detected as USB connection instead of AC and charge at limited amps because of it. Swapping out to a new stock cable or even a dedicated charge cable with no sync pins usually solves the issue. EDIT: as przemo3679 says below, Qualcomm Quick Charge standard negotiates the higher voltage mode over the data pins, so "charge only" style cords with the data pins missing or shorted will not work in QC mode.

no, the snapdragon 810 has overheating problems so if the screen is on the fastcharge is disabled, is the same reason because while you play and the phone heat up the display brightness cant be over 75%.

It does not disable the fast charge simply because the screen is on. That is how you keep phrasing it.
It disables fast charge if the phone is overheating. Technically this is not the same thing.
Many common usage factors (gaming, heavy mobile data use, high screen brightness, etc.) can make the heat build up fast enough to trigger thermal throttling and disable fast charge of course. But it is also possible to tweak the kernel and thermal files and adjust usage (light browsing only, use strong wifi in lieu of mobile radio, reduce screen brightness) to keep the phone in fast charge even when screen is on.

I disagree. If phone is charging, but not fast it is usually caused by damaged data lanes, or too big resistance on some lane. Cables without sync lanes would work on some devices, but would not on others, current will be limited to 500mA. It's hard to say on which.
And w/o data pins quick charge can't work on any device. Phone use it to communicate with charger to set best voltage and current to actual device.
As i said, original is the best. U can't blame damaged cord for charging issues.
I have a usb voltmeter and I can assure you that it use the 9V charging while the screen is on and also when it's in use (so the screen is on and the phone is in use). The amp only drop when percentage is near complete charging but stay at 9V so technically it still use fast charging.
Quality of the usb cable is very important but quick charge (or fast charge as LG call it) use of higher voltage make the quality less important. I can use a 3 meter usb cable for example, with a iPad charger (5V 2.1A and genuine) I can't even charge my flex 2 (it can't draw more than 300mA and the battery deplete more slowly but don't charge even is not in use). I won't explain why a higher voltage is less sensitive to resistance (the resistance rise with the lenght of the wire) but that's the reason we use high voltage line to transport electricity.
OP here. I use the stock charger and cable that came with the phone, plus they dont see damaged or very used. Still feeling it "slow" :s
I have H950 Stock 5.0.1 , sometimes quick charge doesn't work properly so I turn the power off and charge while off for half an hour it charges very fast and reaches over 70% then turn it back on

I agree with You, in short words more current (A) means more temperature. At the same power (W) bigger voltage (V) means lower current (A). But i think u didn't get what i mean. There is some kind mechanism, which block quick charge when cable is too crapy. I had one of those, and it was fully functional witch data lanes, but it was designed to power 0,5A device. When i tried to connect it to the Flex it said slow charging (or something like that). I think it somehow measures resistance.
I also want to refer to your words: "quick charge (or fast charge as LG call it) use of higher voltage make the quality less important". It is advantage of the quick charge, but not main purpose. U can always made a bit thicker lanes. But you can't change connector. Remember that USB 2.0 standard was designed in april 2000, so it is a bit old now . Back in the days nobody was thinking about 5,5" monsters with 3Ah batteries. Flex is charging with around 15W and it is too much(it can dangerously hot, create arcs etc.). Remember that conductor heats up the most in the greatest resistance point, which is connector. Now we have USB type C, with better connector, which can hold on greater currents, but if we have standard, why did not use it (QC2.0 & QC3.0), and have thinner cord?
About charging time, mine from 0-10% to about 90% takes about an hour.
Guys i solved the problem, after noticing that now the animations (rotation, multitasking, and others) werent working, i decided to do a hard reset, now everything is working, fastcharge, animations, etc. not sure what was the cause, a friend told me was a virus for watching porn lol

I see exactly what message you get, it's the same message when you connect to a computer, right?
It detect a computer and limit itself to 5V and 500mA which was the standard back in the time.
I know someone that fried a laptop motherboard with a vaping bypass, so that limit have purpose.
What is strange is if you get that message with a faulty cable and a lg fast charge charger because the charger should only send signal to negociate quick charge.
I don't think it can measure the resistance or the intensity, or at least the measurement is not monitored in some app because when I use a cable with high resistance and the battery percentage don't go up, I don't have that message.

My bad with translation. If you have no data lanes phone will usually charge with 0.5A as You said, but when i used this crappy one it was something closer to "To maintain best performance use original standardized charger". It was charging faster than 0.5A, but it wasn't QC.

I think you mean the opposite, without the data pin (2 center pin on usb plug) the phone will think he is on a charger and don't limit itself for drawing current even if it's connected to a computer.
Normally a usb device have to be limited to 5V and 500mA,
But qc need the data pin to negotiate the qc voltage so if you use a usb cable without data pin it will stay at 5V.
I have one cable that top at 5V and 100mA (around 80mA normaly) it's very low and it can't charge the phone, it just make it lose battery more slowly, in that case I don't have the message you talk about. That message should appear when it's connected on a computer. My usb voltmeter also have a feature to block data pin, when that feature is activated the message don't pop and it draw more than 500mA from a computer.
There is a good voltmeter on aliexpress, I can make you the link but it's easily recognizable with a transparent blue case, around 10$. There is many model so be sure to take the quick charge compatible. You can make theory on many things but you can truly understand only if you try by yourself.
