Is there a program/driver that will allow the leo to pull more than 500mA when connected via usb? My TP2 (CDMA) has this installed and its bad ass. I can charge faster off things like a cable box (or my computer) than the wall. It pulls ~928mA.
Right now I have a Y adapter.. I plug the power only usb into the computer and the data into an external source (like a duracell powersource mobile). tBattery reads "AC" for charger input. Then, I unplug from the powersource and plug the data part of the usb Y into the computer, hopefully forcing it to switch to usb mode while retaining high current draw. No dice, its still on AC.. and the data cable is not communicating with the computer/phone. If i were to unplug the power only cable, it would probably switch right over to usb mode and WMDC would pop up and all that. But.. I would be limited to 500mA, which is.. really weak since the phone can only use about 150 of that for charging!
Charge with your phone off may help?
That is not possible, because PC can't give more than 500mA on one USB port.
Check in Windows device manager (PC) and find Generic USB Hub. Then look on "Power" tab.

You can't. You could burn USB port in your computer.

This is a screenshot taken from my touch pro 2.. Plugged into the usb port of my laptop. This is possible. It also is possible with my cable box. It requires a driver/app from nuerom..
http://www.nuerom.com/BlogEngine/po...g-nueBattery2-For-TP2-CDMA-v12-Build-122.aspx
btw.. ports are either in high power or low power.. 500mA should really say 500mA+... Some ports are NOT capable of doing this.. I'd imagine I could trigger the same by connecting devices to all three of my usb ports on my laptop.
many gigabyte mainboards have the function to deliver 3x more power through usb ports. ive tested myself and can only confirm it is charging within 1.5~ 2 hours completely
Yeah - maybe, but if... higher charging amperage causing battery/phone overheating and dramaticly shorting battery life. I know, that dedicated HTC HD2 charger having 5V and 1A (1000 mA), but this is TRAVEL charger and should be used only in this situation by reasons previously wroted by me. I charge my LEO only with PC.
i think it depends on the charger itself. i bought a docking station and while reading the manual i came across a switch that changes the mode between "charge" and "sync"
this lets your device acknowledge that the charger is capable of providing more mA than a normal USB port so that it can draw more power.
The ac charger (or the battery driver itself) is smart enough to trickle down the charge rate as the battery reaches maximum capacity. We have an aluminum battery cover that seems to have a heat pad to transfer that heat from the battery. The battery driver probably has provisions to stop charging if batt temp reaches a certain #.
500mA charge is not enough. The phone itself is able to draw more current than a 500mA line could provide.
I just plugged a y adapter into my laptop. Plugging only the power portion in. tBattery says USB for charger input.. Taking the data/power 'part' of the Y adapter cable and plugging it into a usb power source (with no data pins, like a duracell powersource mobile) puts the phone into ac charger input. I disconnect the duracell charger and leave only the phone plugged into my y adapter to my computer... still says AC charging.
I'm now able to charge the phone using 1 computer usb port. World doesn't end. Phone doesn't explode.
Pictures are worth a thousand convoluted paragraphs.
i bought two extra usb cables from amazon, i can't link to them since i don't have enough posts yet, but they're the "EMPIRE USB Data Cable for Verizon HTC ThunderBolt" from amazon
i intentionally looked for some that said for use with thunderbolt in case there was something different than just a micro-usb cable; however, it does not seem that these cables charge as well as the cable that ships. it takes several hours even when trying to charge with the original AC adapter using one of these cables vs the ~1.5-2 hours with the cable that comes with. When trying to use a computer or a car adapter it just holds the charge steady, if using navigation it actually drops battery while plugged in!
is there something i'm missing here? they should all be the same right? can anyone point me to some that actually work? (preferably from amazon since i have gift cards there)
I've had the same problem.
Make sure you are getting the correct voltage. I think my issues are that USB is a slower charge than outlets and the "extra" charger I had was for my bluetooth which had a lower voltage.

yeah, i understand that usb from the computer will be a lower voltage, which is what i thought the issue was at first. but then i tried using the original AC adapter with the replacement usb cable and it was slower than the original cable. i don't see why the cable would make a difference, but it definitely appears to.
i downloaded the current widget and can see that just swapping between the OEM cable and the aftermarket cable the charging current is quite different. ~+600ma with the OEM and -100ma to +300ma with the aftermarket (yes at times it was LOSING charge while plugged in using the aftermarket)

You should never use any other cable than the one provided with your Thunderbolt. On the site it may say that it "Works" with the Thunderbolt but that doesn't mean you are going to get the performance you need out of it. I have had that problem plenty of times with older cables and sadly it keeps me buying the slightly overpriced cables from Verizon so I know that I get what I need.

It sounds like a defective cable. Check to see how it's charging (AC or USB). If it says USB when connected to the HTC charger, the cable is bad.
I use micro-USB cables I got from Monoprice, no problems.

It's not defective, it's just not designed for charging. OP, always make sure it says it is a charger cable, not a data cable, when you buy one.

BS. You have no clue what you're talking about. The TB follows the USB charging specification.
The thing about USB (Universal serial bus) cables is that they are UNIVERSAL. It doesn't matter where you get them from, what they say, or what they are branded. They have to meet certain specs (including materials and current capacity) in order to get the USB label.
If you're having a problem, I am 99% sure the cable is not the issue.
Try out monoprice.com. I've used them for years. You can get 3 wall chargers, 5 USB cables and 2 car chargers (all 1A) for like $25, shipped.

yeah, i'm with you, that's why i posed to see if there was something i'm missing and didn't know about. i'm a computer engineer so i know a cable is a cable is a cable, which is why i was like wtf when these didn't work the same.
thanks all, at least i know i didn't miss something and these should work the same.
ive had this problem on every phone. takes forever to charge through usb.
A USB cable is a USB cable is a USB cable is a USB cable.
If you are doing seat of your pants checks on charging, etc, they are never going to be accurate. CPU usage, network usage, etc while the phone is charging will affect how quickly it does charge. The stock charger provides 1000mA to charge the device, if you are using it, or another app is doing something (downloading data, using cpu, etc) it will not charge as quickly because power is being drained as it is being charged.
There is too much that would cause a slower charge state that you can't compensate for by a seat of the pants judgement on charging.
Its all about the mA.
No, thats not a storm. Its just my Thunderbolt layin down this post.
I have the same issue. I have tried four different usb cables with the oem charger and only two charge normally, the oem and one that I had with an old phone that I put a mini to micro adapter on to fit. The other two, one actually micro one mini to micro adapted, charge extremely slow. Yes a cable is a cable, but given I use the oem charger, the only differing things are the cables.
For what it's worth, I hate to burst your bubbles but not all USB cables are equal. And, in fact, not all phones are optimized for USB cables. Just because a cable looks like a USB cable and works as a USB cable doesn't mean that it is ONLY a USB cable. There are quite a few devices out there that can be charged (albeit slowly) with a USB cable but can be charged quickly with a cable that you only think is a USB cable. Take the Nook Color, for instance. The cable that it comes with looks like a USB cable on all accounts, but it's not. I forget which (both are techniques currently used) but either it has extra pins or has a data pin repurposed to provide additional power so it can charge faster. There are quite a few devices out there that are like this, and it seems like the number of these devices just keep growing and growing.
Now these "non-USB" devices still support USB standards, and can be charged via USB standard cables. However, they are optimized for non-USB standards and charge faster with these non-USB cables.
I'm honestly not sure if our Thunderbolts are such a device or not, and if the cables that they come with are such cables. They very well could be, and what the OP claims goes along with that theory. But honestly, I simply do not know.
EDIT:
Oh, and one more example. Go take a look at the custom "USB" cables that Team Blackhat had made that can power Motorola devices in CWM without a battery in the device. This is yet another example of where a USB cable isn't a USB cable.
Having the data pins connected to 5v sources is part of the charger itself; it has nothing to do with the cable.
Every USB cable has 4 pins: two 5v+, a gnd and a 5v- if the second + and - aren't connected to a source in the charger, you will only get a 0.5A charge, and it will go slow. If the charger DOES have them connected, you get the full 1A, and a much faster charge.
If the charger or cable is anything different then it is not USB. End of story. I know some phones have extra pins in the USB location for video out, for example, but those don't interfere with the standard USB pins.

Wrong, kinda. Check this out: http://en.wikipedia.org/wiki/Nook_Color#USB_port
The Nook Color uses a modified connector with two depths. The first depth is compatible with micro-usb (5-conductor), while the second depth has 12 conductors. This change was made to increase the amount of power available to charge the larger battery of the Nook Color when using the included cable.
Because of this, the USB cable included with the Nook Color is physically incompatible with other devices employing standard micro-usb connectors. However, the Nook Color itself is physically compatible with standard micro-usb cords.

Now I realize that calling this a "USB Cable" might be stretching the definition of "USB Cable" (hence the "wrong, kinda" comment) but more than likely, most people have no clue that one cable is different than another, so the end result is that, for all practical purposes, we DO have different types of USB cables.

Close, but not quite.
The pins are +5, Ground, +D and -D. All power is drawn through the +5 and Ground lines. The D lines are used for data transfer.
Per the USB specifications, a device can only draw 100 mA without enumerating (negotiating via USB, implies both ends have "intelligence"). If it can enumerate, it can negotiate for up to 500 mA (e.g. plugged into a PC which has a "driver" which recognizes the phone).
There are also specifications for DCPs (Dedicated Charging Ports). For these, the D+ and D- pins (the center two in a full sized USB connector) on the charger must be connected together with no more than 200 Ohms. These ports must provide at least 500 mA, but can provide more (micro-USB connectors are rated to 1.8 A). That's how the phone knows it can draw more than 100 mA from a "dumb" power adapter.
The TB follows the USB charging spec. Here are some things that can happen.
If it's plugged into a charger which doesn't follow the USB spec (D+ and D- not connected together, these are fairly common), it can only draw 100 mA. It doesn't matter if you bought a "2.5 Amp USB charger," if the charger doesn't follow the spec, a device which does isn't supposed to draw more than 100 mA. That's enough to charge it very slowly when the screen is off and it's idling. If the phone is doing anything, the battery will actually be discharging. This is a problem which seems to be common with many car chargers. A lot of device will ignore the 100 mA spec limit, and draw whatever they can, which is why they will charge from an improper adapter.
It's plugged into a PC with no driver - same thing.
It's plugged into a PC with a driver - it can negotiate and pull 500 mA. This is enough to charge while running in almost all cases (it might be on the edge if streaming video via 4G with GPS on, etc.) It will charge, but not as fast as it could.
For all of the above, a TB will show "USB" as the charging type.
It's plugged into a USB DCP. By spec, these must be able to deliver at least 500 mA. The AC adapter shipped with the TB is marked 1.0 A, and the phone won't draw more than 1.0 A (the most I've seen it use to charge the battery is ~800 mA). This will allows the fastest charging. With a DCP, the TB will show "AC" as the charging type.
Cables can have the same effect - all USB cables are supposed to be basically the same. But, some manufacturer's play loose with the spec. They may have "USB" cables with resistors or other changes inside which signal different things to a device. They may not have proper gauge wiring. It may just be a bad cable. Etc.
I've charged the TB with the stock AC charger using both the stock cable, and one I got from Monoprice. Works fine. I've also got a USB hub I converted to a charging station (follows the spec for USB dedicated charging ports), and that works fine with both the original and the Monoprice cables.
I have run into "flaky" cables, where they only work right if jiggled around a bit. Maybe they've been flexed too much, and have an intermittent connection. Maybe the contacts have gotten dirty. I don't worry about it, I just throw those away, you can get new ones from Monoprice for less than a buck.
Thanks Mike S (Also my initials, lol) That's what I get for posting after staying up a bit too late.
well i just ordered two micro usb cables from monoprice. we'll see if those fare any better.
the only thing i can guess is the power wires are a small gauge in the cables i bought from amazon. monoprice has two different kinds, some use 28awg for both data/power and then they have some that have 24awg for power and 28awg for data. i'm hoping that getting the bigger wire for the power will solve the issue.
also, i've been using juiceplotter and you can visibly see the slope of the charge change when switching just between these cables i bought vs the stock one when using the HTC charger so i'm pretty certain it's the cable.

Battery Monitor Widget will do that, and more, including telling you whether it's charging AC or USB.
You can also check the charging type from Home Settings/About Phone/Battery/Battery Status.
Hello
As you know, our device doesnt get charged by the USB cable it comes with (or veeeeeery slow).
As I have a solar charging device with USB slots, I need a compatible USB cable. Somehow it has to work, is there some converter or something ?
Thanks!
Dominik
Eh? My device charges just fine with the included cable.
You will have trouble charging it from a solar powered USB charger as I'm guessing it will only put out 5V at maybe 500mA. That's not enough to juice the TF. It's not the cable though.
Because ASUS used a USB connector on its cable, unfortunately does *not* mean this USB connector 100% follows the specifications for USB.
It has a trick, whereby, when connecting to your PC it works like USB at 5v. But, when connecting to a 15v charger it switches to use 15v instead.
The TF charging indicator, and Android OS battery settings, only indicate charging when 15v applied. At 5v it may trickle charge with screen & wifi & ??? turned OFF. I never try charging at 5v because it is too slow.
LOL
I don't think it charges at all at 5v?
EDIT:
How can I delete a post?

It will, provided you have the amperage. But its only trickle so its only really charging with the screen off and charges slower than the tablet uses battery.
FWIW, I think I may have traced my recent charging problems to a Belkin USB charger at my office. On this power source, the battery indicates charging from USB, and apparently there's not enough current to keep up with the demand of the device. It discharges continuously with the screen on, and only keeps even with the screen off. The only way to charge with the Belkin is to turn the phone off.
With the included HTC adapter at my home, however (and with a Motorola adapter left over from a previous phone), the Rezound will charge with screen off, and perhaps even a little with the screen on. Allowed to charge overnight, I do not have to turn the device off when using the HTC charger. On this charger, the phone indicates AC power.
Of course, none of this was an issue before I took the ICS leak. Even though I've gone back to GB, I still have the ICS firmware, and I suspect something different in there is affecting charging.
In fact, I wouldn't be surprised if HTC simply lowered charging rates as part of a campaign to deal with widespread heat issues. If you were trying to cool the phone, that's definitely something you would consider tweaking.
For sure, it's a known issue, some chargers give the full 1A ( the phone indicates AC charging) and some only give 400ma or less (USB Charging).
Search around for chargers and there's good discussion on AC adapters that work well, and even how to modify a USB wall/car charger to give a full AC amount.
Both my gigabyte and msi motherboards are able to deliver up to 1.5A via the USB ports, and are even able to charge my phone (or tablet) when the computer is OFF.

for sure, but i bet your phone is only commanding 500ma from it since the phone is usb 2.0 spec... I too have a power port on my laptop to charge things when the laptop is off but it doesn't get over usb 2.0 spec because of the phone :x
I've tried everything, short of trying to make, or looking for, customized drivers to overload it.

You might be right when it comes to the Rezound, but I know for a fact that it is capable of supplying more than 500mA to some devices for charging. It charges my TF101 even with the screen on, which every other computer with ordinary USB ports seems incapable of doing. If I plug my TF101 into any other computer with a standard USB 2.0 port, it will still slowly discharge if the screen is on and I'm using it.
Either way, I notice absolutely no difference between charging via USB on my computer or via the actual charger, so I'm relatively sure the USB port IS outputting at least the full 1A that the actual charger is rated at, and I am NOT using a kernel with the "fast charge" mod..
I haven't really spent much time noticing how slowly the Rezound would charge on a regular USB 2.0 port. Maybe I'll give it a shot on my laptop tonight just to test it out.
Or, a simple ammeter would probably put the issue to rest definitely.. I wonder if I know anybody with one I could use.....

Use a charging only cable, i.e. Naztech Micro USB Charging Cable (sorry, don't remember who initially pointed to this), and the phone will see the source as an outlet and not a usb port.

Well that makes sense, any USB cord without data points can only provide power and therefore the phone wouldn't be able to determine whether its a computers USB port or a charger. When the data pins are present, the phone must request a high-power mode from the computer in order to obtain the full 500mA on standard ports, or 1.5A in the case of some newer boards as I mentioned earlier.
Vs985 on CM12. When I plug my phone with the LG's native USB into my Honda - it does not seem to charge. It only changes to show a battery indicator amount of charge. Even with charge only selected in the usb settings. If I plug my phone into my laptop it shows a lightning bolt in the battery icon and seems to charge? Is there some kind of a device I can plug into the usb or something I can do on the phone to enable usb charging?
If it were me, I'd try it on a stock LG ROM to determine where the problem lies.

When plugged into your laptop, or desktop for that matter, your phone WILL NOT charge at the same speed as it would when plugged into a wall charger for the express reason that the outlet will provide a higher voltage, one capable of charging the phone, while the laptop doesn't provide as large a voltage through it's USB port because many USB operated devices for a computer require a much lower voltage to operate properly. As for the Honda charging, I believe it would be the same deal, but I'm not an expert on vehicles so I'm not positive.

I hope you don't taste this the wrong way, but to some like me, it's a pet peace. ? The voltage is the same,the amperage is different.
I believe computer USB 2.0 and 1.x ports are normally limited to 500mA (half an amp). Some PC's USB drivers even let you monitor how much amperage each USB port is drawing when it's bring used.
USB 3.0 might be higher. I'd have to read again to be sure, but the additional amperage USB 3.0 might supply shouldn't require a USB 3.0 cable to take advantage of it.
Some implementations of USB in some PCs supply higher, and presumably some lower amperages than the known standard.
