Hey
Whenever ive had a phone with a usb port in the past ive usually charged it via USB connected to my PC. However, with the desire it takes about 45 mins to improve battery by 1% when connected to pc, whereas is takes about 1 min to do this when connected to AC. Ive never had this with any other phone which is why im wondering whether theres something wrong there
anyone else have this issue?
I'm pretty sure most devices do this.. any I've toyed with have..
it might be slower, but its never been this much slower. In fact, ive just had it plugged into usb for the last hour and the battery has gone DOWN 3%!!!!!
The current that you can draw through a USB port probably isn't as much! can't remember what the USB standard is but it's more that likely a lot lower than the AC charger
Yes, I am experiencing the same thing. On USB 1% every half an hour, on AC like 1% per minute. Still, I don't know what is causing this. The output power of AC and USB are different, but they shouldn't be this much.
is your laptop running on the mains or battery?
is your charging cable original (htc desire) ?
my laptop is running on the mains/AC but i am not using the cable that was originally bundled with the desire....should that make a difference though? Surely a USB cable is a USB cable?
Same here. Very slow on USB.
Wiki says this:
However, many devices require more power than this method can provide, and will not work in this type of hub.
USB current (related to power) is allocated in units of 100 mA up to a maximum total of 500 mA per port.

ive generally always charged my phone via USB and never had this problem with any phone. the desire must be sooo power hungry. Im actually at a stage now where even if i plug it into the USB port, it still loses charge
One usb hub can provide up to 500 miliamps of current, one port just 256. The ac adapter can give you 1000 ma. So do the calculations yourself

Since I have had my desire I have never charged it via the charger my pc charges it even when its turned off and I've never had any problems with charge speed.

i found the htc cable to be more effective than a micro usb one from samsung.
I've charged my phone from my PC loads of times. Takes about twice as long (roughly, I've never actually timed it).
Definitely not 1% per half hour though!
What is your setup and are you doing with the phone whilst it's connected?
With WiFi and 3G and the screen left on, I get +1% every 3.6mins using the PC USB.

no, i definately dont get it charge that quick. Also, for the record, when using gps connected to a car charger, it doesnt ever charge, it only loses charge at a much slower rate (not good for long journeys!) unless i switch the screen off
When its connected to the pc im usually not doing anything with it. If even tried it with the phone switched off before, charged it like this for an hour and then when i turned it back on it had only charged by 2%
what do you want to know about the setup? Could it actually have something to do with the fact im not using the original bundled USB cable? I just cant see that being a factor
something is definitly wrong with either your cable your phone.
Let's try to cancel out one of those factors:
-have you tried using a different able?
I have NEVER used the AC charger, i've always used the usb charging method, and it takes about 2 hours for a half charge.
ill try using a different cable and see what happens. could the fact im charging it off a netbook be a problem? i wouldnt have thought so as i always charged my last phone (touch diamond) off this netbook too
ok, so it seems the USB cable used DOES matter. When using the original one it charges a lot quicker via USB ... AND AC
i didnt realise different usb cables have different power transfer rates....i guess now i do
Do this test.
Try to charge the phone while it's off.
The power controller of the phone needs to split the power between the phone requirements and the charging of the battery.
I think that your phone is drawing to much power so there is very little left for the battery charge.
So 1. test the usb cable 2. test the power consumption of your phone.
I have no problems charging my phone, when it's connected to my desktop.
Use it all the time at work.

Hi.
i got a unbranded Touch Pro2 in france. the battery stand 2 days before the first recharge. but seems i got a problem of recharging.
i decide to recharge it when the phone is ON, but seems it consumes more than recharge speed. there are less and less electric in the battery, even the screen is Off, and no applications running, and all connections are disabled (WIFI, Bluetooth, Data Connection) except Phone
so i have to take the phone completely OFF, with a cable USB connected to the computer, now it is more than 6 hours, but the recharing light is always "Orange".
this is my 3rd HTC phone, and i never met this problem before. as the first recharge of TP2, is it normal to me?
thanks in advance of your help
Try the supplied wall charger - will do the job a lot quicker!

Thanks, nearly 6.5 hours with usb cable. the light turns green, so i can start it now.
but i still not understand why it consumes more quickly than recharge. i will see if it happens only in first charge.
I saw somthing somehwhere about turning on quick charge or full charge via activesync usb, dont know what its about but its worth investegating if this is a problem for you.
I have another charging or connection problem, with all my other htc phones (5) i could use any regular usb cabel, with the pro 2 they all seem to have poor connection, have to hold the cabel in a sertan angel for it to work. The supplied cabel and the org cabel for my pro 1 works fine though. Anybody else having this issue?

same here - but applies to all my htc phone. they can not connect stability with the mini-usb of my SLR camera. in fact, there are a little different with HTC ext-usb and mini USB -- the port is a Right-angle trapezoidal, while the standard mini-usb is Symmetric trapezoidal. so that's why we should use the ext-usb cable.
same here with the usb cable ...well is not the usb cables problem but the usb plug in the phone .
concerning charging from a pc laptop.....
if i leave my phone overnight charging from the laptop and the laptop goes into standby ,even if the battery is 100% it gets totally discharged with in hours!!!! this while plugged into the laptop!!!
what a hell is this , i mean, m i charging the laptop from the pda or what!?
this is a serious bug that htc needs addressing.
please note that there is laptops that do not power down usb ports while in standby, i got one that does just that.
now my eee-pc1000h doe power down the usbs ports when going into standby.

Well i know that but that is becous they also have the headset on the same port. As far as i know you should be able to use a normal usb cabel with the device.
USB ports on a computer can only supply 500Mah of current. it seems really odd that the phone would be discharging at such a rate to deplete itself even with that current available. that would seem to indicate the 1500Mah battery in the Tp2 would only last 2, maybe 3 hours before dying if left unplugged.
when connected through a Wall outlet the phone should be being charged at 1000Mah. although the maximum safe charge rate of the battery is 1.5Amps (1500Mah.)

I have noticed that my TP2 can complain with a popup warning that there is insufficient power to charge when connected to my Dell laptop. I think it just stops charging at this point. After that it is downhill all the way!
I agree that there is something strange going on with the TP2 recharging from a USB port. I got my TP2 as a replacement for my HTC Universal. I am using the TP2 on the same port with the same cable. The Universal was very straightforward - plug it in and it charged regardless of whether it or the PC was on or off. The TP2 is very different - leave this connected to a powered off PC overnight and I routinely find that the TP2 has reached critical battery low the next morning. This means that not only does it seem not to have been charging, but it must have been "on" overnight (where the power management settings should have turned it off) in order to deplete the battery to this extent, regardless of whether it was charging or not. The battery charging light (amber to the left of the ear speaker) is on throughout.
The power management information is also odd. This AM it reports last full charge at 23:12 last night and since last full charge a standby time of 6h39m, talk time of 0 and device usage of 2h55m. However, it wasnt used at all after about 20:00 last night and power management should have turned it off after 30 mins.
It charges normally from the USB port when the PC is on.
Any ideas?
This problem happens with standard USB cables and the official HTC cable. You must have an active ActiveSync connection or the phone won't charge.
Last night I plugged my phone in while my computer was still booting. The charging light came on, but this morning I was left with 10% battery.
If you plug it into a computer without ActiveSync installed the phone won't charge.
If you plug it in and the ActiveSync icon turns green the phone is happy and will charge.
If you turn off the phone and plug it in to just about any USB power source, the phone doesen't know better, and it will charge.
I got the power error in my car last weekend. Running with the splitter, with 3.5mm into car sterio and car charger plugged in. Was running slide2play and the pop up showed up. Come to find out, later on the charging light wasnt on the phone anymore. Tried the wifes tilt 2 and it wouldnt charger hers either. The car charger died.
BUT, at the time the error came up, the charging light was up and running.

Problem with TP2 and Mini USB sync/charge cable
I have an unbranded GSM TP2. It charges normally using the HTC wall charger and the HTC supplied ExtUSB cable.
I have read that Mini USB cables should be compatible with the HTC ExtUSB port for normal operations like charge and sync so I bought a generic Mini USB sync/charge cable on e-Bay. The supplier stated it was compatible with TP2, but when I plug it in to USB port, the device charging light comes on for 1 sec then goes off and the PC shows a message saying "a USB device has malfunctioned".
The supplier sent me a replacement cable but it has exactly the same problem so I don't think the cable is faulty. I think maybe the problem is with my device.
Does anyone out there have more detailed knowledge of the compatibility of Mini USB and ExtUSB?

No, I am just using ActiveSync to sync my data and charging via USB whilst connected.
As I said, it works perfectly with the standard HTC ExtUSB cable but fails to connect properly when I try to use the Mini USB cable.

I think the odds are you just got a bum USB cable...the failure rate among the generic ones on e-bay is considerably higher as a rule. Do you or any of your friends have any other mini-USB equipped devices you can test it with?

That was my first thought but I have now tried three different cables, from two different e-bay sources, with the same effect. However, I haven't yet tried any of them with any other device - I'll try that at the weekend and see what happens.
so the option to not charge it is not ticked under power settings, and its set to charge via usb from advanced config and still no dice.
tried different usb ports and nothing
the led is orange, says its charging in power options
any thoughts?
Try a diffrent usb cable, some cables do not provide enough power to charge the phone. (guessing maybe they are old 1.1 cabels). But I know I have a few cables around that dont charge my phone and they also will not work with my portable external usb hard drive because they wont provide enough power for it. But they work just fine with my digital camera.
I´ve read somewhere that disabling USB charging is better for the battery life, so I have it disabled.
You've tried different USB ports, but were they on the different computers?
so i've tried different cables, different ports and 2 different PC's and 2 different laptops.
I know its not the cable i'm currently using because i plugged it into one of those A/C to USB adapters and charged fine.
I'm starting to think its my batter,
If you have tbattery installed, do u get values for all the boxes?
All mine except 3 or 4 are 0 :/
Well, you are not the only one having this problem. Mine is brand new. I started setting it up last night and had it hooked to the computer via usb. I installed a few .cabs such as google maps, myphone, and a few tweaks such as tether, disable sent notification, enable all camera modes, and manila start menu unlocker. While it was connected it said it was charging. When I went to bed I turned it off and connected it to another usb cable on another computer which is an a/c hub. I went to turn it on this morning and thought it was strange it was not fully charged. I continued to set it up a bit and take it for a spin. After a while I turned it off again and hooked it to the usb a/c charger again. I just tried turning it on and nothing was happening. I connected it to the usb again and it finally turned on, but I checked the battery level and it was at 0% and turned off. I have it connected to the a/c charger and giving it a little bit to see what will happen. One thing that seems strange is that the battery discharged more while it was off and attached to the usb a/c hub during the afternoon causing it to refuse to turn on at all. Any thoughts?

I think the odds are pretty good it's your battery. The orange light means power is going through the charging circuit, so you obviously have your settings correct.
I'm guessing you're in Austin or near? If you want to try popping my battery in it for a few minutes and see if it charges fine then, PM me and we can set something up.
the same thing is happening with mine. Sometimes it will charge, sometimes it wont. weird thing is that it only started doing this a few days ago... i know nothing has changed ROM wise, so only things i can think now is maybe the actual USB connector on the phone or the battery, but since I am getting a charge via wall chargers im not sure what to think lol
Just an update.
If i have the USB cable plugged in (and car charger to which doesn't charge as well ) after 15 min or so a warning appears saying that the current is too low to charge the device. Either closed unused apps or switch to a/c power.
I've ordered a 1800mah Mugen Power Battery. Gonna see if it resolves the issue, if it does then i'm gonna call at&t and see if they'll swap my battery for me.
I have found as have others here after reading some posts that if the phone is almost dead or battery is very low then it will not charge via the USB anymore. The orange light goes on and it says that its charging but the charging circuit seems to be protecting the phone and not letting the battery charge.
The only solution I have found, and it has only happened twice so far is to plug it into a wall charger and fully charge the battery. It will then charge via USB again and all is good. I normally only charge my phone with usb while connected to Activesync but once in a while you seem to need to top it up with a wall charger.
It is also highly recomended not to run Lithium Ion batteries right out.
How do you know it is not charging?
There is a difference in the wiring from a wall charger and a USB charger. There is a signal line in the wall charger telling it to charge at near 1000ma. In the USB cable that line tells it to limit the charge current to 500ma. That is the limit for current that you should pull from a USB port. If you are using the unit heavily, you may actually need more then the 500ma., those running the battery down possibly.
If the unit is idle, it will still take much longer to charger from USB then off of a wall charger.

If you are asking me, I know it was not charging because I also had the "not enough power to charge message" and the phone went from about 15% when I plugged it in to stone cold dead by the morning. The whole time it was pluged into a computer I have used repeatedly to charge it with. I then put it on a AC charger and it went to full charger in about an hour and a half or so.
My battery usually takes about 8-9 hours to charge (from about 10%, so it's charging a little over 10% per hour). I'm using the USB cable that was in the box, and it's plugged into my laptop. Is this normal? It seems like a ridiculously long time. If I bought a wall charger and used that instead would it charge faster? Or if I used the USB cable but with a desktop instead of a laptop?
Usb will be slow its going to be the same on desktop or laptop. They just don't put out the juice. Wall charger is very fast to charge.
Should be MUCH faster with a wall charger, USB charges are usually quite slow.
EDIT: beat me to it...
Nah it's slow regardless of whether you charge it via USB or wall charger.
It's not the only phone that charges that slowly, e.g. the HTC Touch Cruise had the same issue (but not the HD and HD2).
One method to test this is to plug your phone in and use it heavily (e.g. for web surfing or GPS navigation).
Most phones will still charge the battery then, but the Desire is one of the phones that actually lose charge. It doesn't get enough charging current.
Sucks, but you can't do anything about it. It's a hardware design issue.
Well my phone charges slow as f..... through the usb connected to a computer aswell.
But it charges in like an hour or two when connected to the wallcharger.

Which, as mentioned, is normal.
Hi,
Was reading about this issue in some android-board a few days ago - just can talk for the htc desire, but there is something special in the combination of original usb-cable and original wallcharger!
Only with this combination the desire is loading with 1000mA - if you plug the desire to another wallcharger, even if this also supports 1000mA or more, or to a laptop or a pc, the desire will be loaded with only 500mA.
This would be normal for pc or laptop, as the usb-connectors don't support more - but it is strange that even on wallchargers with 1000mA or more the desire is also loaded only with 500mA!
On the desire you can check this under Settings-Telephone-Battery - if you're connected to pc, laptop or a not-original wallcharger, you can read here: Charging (USB), with the original wallcharger it reads Charging (AC)...
Alright I went to a Verizon store and bought a generic micro USB wall charger and it's A LOT faster. It seems like it takes a little over 3 hours to charge, does that seem about right?
Yeah that sounds about right really. Think mine does a full charge in roughly the same time from almost dead.
I seem to have an issue that my phone never charges whilst connected via USB to my Macbook Pro. I have also tested on a Windows machine and have the same issue.
I was able to charge my Sensation over USB and I know that one of the ports on the Macbook has a higher output for charging but it makes no difference.
The phone states that it is charging but the percentage charge continues to drop. If I switch the power off it will charge. There doesn't appear to be any big battery drains though. I ran for a day and twelve hours over the weekend and charged at 40 percent.
Has anyone else the same issue?
Btw, I am on stock 4.0.2, rooted but not running anything else that should have any affect

How old is your macbook pro? Or more to the point, do you know if it has USB 3.0 ports? If your higher output ports are just 2.0 (and your computer is describing them as such compared to the older 1.0 spec) then you are stuck at 0.5A (half of wall charger output). USB 3.0 goes up to 0.9A, but I don't know if there are any catches in terms of devices needing to request the bump.
When you say that it charges if you switch the power off, do you mean it only works if you actually power down the phone? As in, leaving it sleeping plugged in, it still won't charge? Keep in mind that actively using the phone with the brightness turned up high could result in overpowering the .5A current in.
Unless you know someone else with a GN you can test you might just want to take it into the store and have them try it there/consider a replacement if it's defective. Also worth exploring if it's just the battery is defunct, if you have access to another one.

Really? Source?
Doing a tad of research it seems some models front (closer to the front) USB port has slightly higher output than the back (closer to the screen) USB port because the back one shares a USB controller with internal components.
It couldn't be noticeable though, they're both simply rated at .5A .

MacBooks don't have USB 3.0. Its always been standard USB 2.0 afaik.
I'd also recommend that OP check different cables and computers, or different batteries if possible.
I have the exact issue. If I charge via USB on ANY laptop/computer it takes forever and if I'm using the phone as it's charging it uses more power than being supplied so it loses battery life even though it's plugged in.
I had this problem on my iPad too. It seems they need more power to charge but can still "trickle" charge off of a standard USB port.
My batter was at 10% last night, plugged it in to my laptop and sent some texts and left the display on (dev settings), about 10 min. latter it was at 4%.
I mean to post this last week!
See the screenshot....Status 'Charging' however as you see from the lower part of the screen, it has clearly stopped charging some time ago (about 3 hours earlier!)
It turns out that the CABLE was the issue....I thought all Micro USB cables were created equal, evidently not
Any ideas what the differences are in micro USB cables and how to identify which ones 'work' and which don't? I bought 10 from ebay which all seem not to charge from USB
I've had no problems charging via my pc using Samsung or Motorola cables. It charges slower but it still works.
Hey all. I finally got my Note 3. I have been using it for a couple of days and, of course, it is awesome. But one thing is troubling me. I charge my phone via my desktop PC, which has several USB 3.0 ports. I first plugged it into the ones on the front, and it wasn't charging very quickly, so I plugged it into one of the back ports, and i'm still having the same problem.
For example, last night, I plugged it in around 1am at about 30%. It's now 7:30am and its at 96%. I would have figured it would be at 100 a while ago. I am using the original Samsung USB 3.0 cable that came with the phone.
I'll have to do a more scientific charging test to see what's going on, but has anyone else seen this?
The supplied charger puts out 2 amps. Which is much higher than any USB port on a PC will ever provide. That's why you're seeing such large disparities with charging rates.

A computer's USB 3.0 port is only spec'd to put out up to 0.9amps, compared to 0.5amps for the older USB 2.0, but the A/C charger puts out 2amps, so use that when charging time matters. I never use a computer's usb port for anything anymore except adb sideloading in recovery (where adb over wireless won't work). Note that SOME computers do have non-standard higher amp usb ports, but it's not that common.
ah I was also wondering why the charger itself charges the phone much faster than my desktop. Good info, thanks guys!
I have bought this item from ebay, it work great and charge the phone very fast

Thanks for the responses people. I will use the plug from now on.
The charging speed will definitely slower than..?
It is the normal case that the speed will be much slower when you charge a device such as your Note3 via USB than via DC Power Supply. USB is mainly designed for the communication. The standard charging current of many mobile phones is 1 A or higher. But the highest output current of USB cable is only 0.5 A which could not reach the source demand of a phone. Except for this, we do not recommend charging via USB because the unstable current output can easily reduce the battery life of your Note 3.:laugh:
