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.

Total nonsense, I plug my phone into my computer here at home to top it off on the weekend and it does not have ActiveStink on it.
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.
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.
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.
As the title says, my desire is not charging it seems, or if so VERY slow so it does run out of battery after a night when plugged in to AC adapter.
I can use USB storage when the phone is on, so it isn't bricked? One thing is that the miniusb connection seems to be bad, I need to push the cable hard, to get it connected.
Anyone recognize this at all? I have never had these kind of issues before. The phone came back from repair some months ago, changing mainboard, and have been working good until now
Hello,
I have a question about the charge of my new S20 (Exynos version):
1) connected to the charger it charges (small 'lightning bolt" on the battery symbol).
2) connected to a booted PC it charges (same for the lightning symbol)
3) connected to the same PC in standby: the symbol appears for a fraction of a second then disappears and it does not charge. It is the same cable and USB plug as in case 2.
4) PC in standby: other USB port / other cable: it is the same, charge symbol very brief then nothing, it does not charge.
Another phone charges without any problem with the same cables/USB socket on the PC in standby ... I do not understand what is wrong.
Same issue with the S20 plugged to another PC ... but ok with other phones
An expert opinion? Thanks in advance.
Its charging board issue
Same issue faced in my s9 then chaging baord changed by service center
I don't understand the "charging" board problem : the phone charges with the same cable when the PC is on, with a charger, with USB in the car...
I was thinking that maybe when the PC is in sleep mode there is not enough power going through the USB port and it won't charge this phone model ?
I think I get a possible answer to my question :
---> using a shorter (about 1 feet only - Aukey brand) USB-A to USB-C cable allows to charge the S20 while the PC is in sleep mode. Any longer cable will only charge the other phones.
--> I guess the S20 require more "power" from an USB port to start recharging. Of course while the PC is on it must have more power as it works even with a longer cable.
Are all the jacks/ports clean and free of debris?
Are the cables good? Partial cable failures happen and charging anomolies is how it will first manifest its self many times.
You'll get much faster charging using the Samsung brick... best to limit charge to 90%, ideally 60-70% to lengthen battery life.
Yes the phone is 2 weeks "old" so no debris in port. It is working flawlessly except when trying to charge it when the PC is in sleep mode ... if the cable is too long.
But I'll use the S9 or S20 charger so it'll be ok.
It doesnt sound like your phone's fault but usb port in your motherboard - if it works fine while using charger then i wouldnt worry
if it works fine while using charger then i wouldnt worry

Agreed ! Even I think the USB port is working fine with every other (older) phone ... but it seems this S20 requires more "energy" to start charging. It is the same while trying with a laptop in sleep mode.
Why would you charge it over pc? Isnt it super slow?

Explanation:
The ports on yor pc when it's sleeping are in power saving mode. It works with a shorter cable because of something called inner resistance of the cable. When the cable is longer but made of the same material it has a bigger resistance therefore the phone does not get enough current to charge. You see the bolt icon for a bit because of a current peak coming from the usb port. Then the phone thinks "damn, that's not enough power" and stops charging.
All of this means that when you connect your phone to charge when the pc is not sleeping it becomes barely enough current to charge, but nevertheless it becomes something, that's why it charges.
Faulty charging board and etc. is not the problem, there is actually no problem. Your phone just needs a current maybe over 1A/5V to start charging, your port probably doesn't have that capacity, especially when pc is sleeping.
Just use the charger, it's much faster and doesn't stress the battery for a long periods of time.

Thanks a lot for you technical explanations. I am using a wallcharger instead of charging the phone overnight hooked to the Pc in sleep mode.
