Samsung SGH i780 not getting charged through USB !! - General Questions and Answers

Dear All,
I recently purchased Samsung i780 India version. The ROM version is i780DDHE1.
I am facing issues while charging the phone over USB. Though the phone shows charging symbol when the usb cable is connected to laptop but even after hours of keeping phone connected to PC there is not battery charging that is happening.
Has anyone faced the same issue or it is something to do while my particular phone piece?
PS: I am able to charge my other phone HTC Gene using the same laptop via USB.
Thanks in advance

It is not an issue, simply i780 can t be charged by usb.Usb connection only keeps your battery status without charging.

Is this openly mentioned/admitted by Samsung anywhere??
also if I use the battery holder & connect it to laptop via usb cable then the battery is charged..how can that happen?
thnx for replying ilMessia
@Mods...
pls move to right section. Sorry for posting in wrong area.

I don t know if samsung say it somewhere.If you connect the battery holder to pc via usb, the battery inside charges because the "usb power" is all directed to the battery.Connecting the i780, the phone needs power to work and there is no power enough for the battery.It means that when the phone is connected it doesn t use the battery power but it only use "usb power".Srry for my english...

Qtek 8310 charging problem

Guys, i think i have a problem with my Qtek 8310.
Whenever i try to charge it with the charger, it will show the amber light indicating its charging from some time and after that it will just shutoff itself and start to blink in red light.
i tried to charge the qtek battery with my other smartphone (SPV C500) its charging properly. I tried to charging it with other charger also, unfortunately no luck.
i started encountering this problem only yesterday onwards.
nowadays, i am charging it through my computer USB and it charges without any problem. Anybody had this problem or heard of a problem like this. Any help is greatly appreciated.
thanks

hi, I have the same problem with my 8310 (1 month old)
the AC adapter doesnt work correctly with the phone
I thought of using another adapter, but I see that you already tried this
the only solution that my retailer gave me, is to make it exchange..
I have the same problem, but if I connect the wifi when I charge it, it works fine....
Really weird problems... Do these happen even when you use the original chargers? Maybe should go back to the store...
I have the same, but i upgrade to Imate ROM 2.5. It fix problem. Now charging well.
I have received a 8310 with the USB-miniUSB cable. I am trying to use it for the first time. When I first started it, it powered on, showed windows mobile, and afte that the battery died, so I cannot power it on. I am trying to charge it with this USB cable. Is it possible when the phone is off?
Should it start charging it when I plug it in in the PC USB port?
And how much time does it need to be fully charged when charging from PC over USB cable?

Touch pro wont charge via usb connection??

Is this normal? cant get it to charge while connected to my usb port?
It says it is charging in the power options, but can be on all day, and as soon as I unplug it its saying no battery left !!!
Also has the been an official rom update yet?

Hi, You don't have the box ticked in the battery screen do you ?
the one that says
When device is turned on, do not charge the battery when connected to the PC
this should be unticked.
dean
Hi Dean
Now I dont have it ticked !!
Any other idea's?
The problem could also be your usb line or usb port. try some alternatives first.
Tried everything, different usb leads, different sockets even different laptops !!
Help
Same problem here. But i changed the USB cable and problem solved. Did u tried it, with the official USB cable from HTC? (I guess so, just to check)
Yep I did !!
Will try again when I get home though..
Thats strange... my TP came with UK power adapter, so I couldnt use AC power until I get an adapter (4 days)... in these days I always charged via USB (all night long)
Well I tried the official usb lead and it charged last night, Im now using the official lead again using same laptop and same usb port and guess what !!! It wont charge again
Have I a faulty touch pro?
shall i phone vodaphone and ask for a replacement

Hi,
this is sounding kinda weird..
What kind of wall charger came with the phone, mine is a wall adapter that i plug the USB lead into to charge the phone
So i know my USB lead works as this charges the phone with both the adapter and via USB on any PC ( i have tried home and work PC's)
Sounds like it could be a handset issue then ???
mine is a Vodafone handset that i bought unlocked and flashed with a different ROM and its working fine..

Laptops can be a bit funny about USB charging, I remember one laptop I had wouldn't charge my phone (SE K800i at the time), unless it was on mains power. The laptop had to be powered up while on the mains, with no USB devices plugged in, then it would supply power to the ports.
My work laptop is also a bit funny about it, I had to disable powering down of the USB ports otherwise it won't power them back up, but since if nothing is connected there's not much of a problem. There is also the possibility it's powering the port, which will charge the phone, but not enough power to actually make it worthwhile, you can check to see how much power is going to the ports by looking under device manager. So you might want to check it's not a problem with your laptop.

This is exactly what mine turned out to be. At work I've got a Dell Optiplex 745 tower and none of the USB ports put out enough power to charge my phone and have the phone on. I've got wifi turned off but the data, EDGE, is always on. If the display is on and I'm in Storage mode there's very little charging going on. It doesn't drain quickly but it definitely isn't going up. If I'm in sync mode it drains pretty quickly and it seems as tho it's not even charging at all.
What I do now is plug it in at work and turn off the display. Kinda sucks but I need my phone fully charged at all times.
I have the same problem....
the usb and the factory usb are different if u have looked carefully
firstable, the shape of the heads are different. secondly, there are 4 pins inside usb and 6 pins inside the factory usb...I guess that's the problem.
Try messing with the USB to PC settings. I know my TP was acting funny and not charging, and after i disabled network functionality, i think it started charging. GL.
Thamks for all the replys, if done everytjhing sometimes it will charge sometimes it wont, I have it connected to my laptop all day for internet sharing, it has charged up very slowly twive, and not at all 8 or 9 times, same usb slot , laptop plugged into mains, official usb lead used ( it never charges from another usb lead )
This is the 3rd htc Ive owned and the first to play up like this over usb !!

Have you tried it plugged into a desktop computer? It would rule out the laptop being the problem if it didn't work. You could also use a mini-usb cable, which could also prove if the official cable is a problem.
Having similar problem...
I'm having a similar problem. My laptop used to charge Touch Pro when i connect it. Now for reason i noticed that it doesn't anymore.
I could be wrong, but I thought I read in the manual that when the phone is synched to a PC, it only charges in trickle mode, so it doesn't recharge the battery efficiently. Is this the problem?
same problem here. Mine was working fine with ANY charger whether it be USB, car charger or wall charger. But now it will only charge with the htc plug but not the HTC wall charger. The plug is the one with the ports for tv-out, headphones.
I'm going to go try and do a hard reset.I dont understand what could cause this.

Touch Pro and tethering woes(battery)

i recently recieved the touch pro as upgrade from my mogul. to be clear the only internet options i have are dial up or tethering and i prefer the ladder. however im finding i cant stay tethered long without running out of battery. where with the mogul i could tether for 12 hrs straight i cant stay on more than 3hrs. i know its power consumption to charhe and it all runs through the battery. my question is would the cradle with seperate charger and usb plugs do anything? would wifi router software work better than tethering? can i bypass the battery and draw power from the cable itself? any help or tips/suggestions from people with similar situations would be great as i have seached here and ppcgeeks with no luck(thus far,im still looking)
60 views and no ideas? Ouch
when you tether your phone, are you using usb cable to connect the phone to your computer? if so, why not set it to charge the phone while it's connected by usb cable? that way u'll just keep drawing power out of the computer and won't have to worry about phone battery draining quickly
it is set that way. the problem is, with the radio running to stay on the internet and with it sending data through the cable, it seems the load on the phone is too great for the charger to keep up sot aht the battery doesnt die down. And since it seems (correct me if i'm wrong) that the way power flow works is all through the battery (charger -> battery -> device) there is no way that i am aware of to keep a charge on it greater than the power consumption. This is why i was asking of docks such as the expansys one http://www.expansys-usa.com/d.aspx?i=169488 where it has seperate data and power plugs on the bottom would work.
Couple of things to clarify
1. That expansys cradle does have two ports on the bottom, but only one is USB/Power the other is a line out for audio, so that will not help you at all, accept to hold your phone up when you're using it.
2. A wifi router option will consume more power than tethering alone, and in my experience tethering, it does infact keep my battery charged. Are you sure that your usb cable is charging your phone? Do you have the option disabled that allows it to charge whilst connected to a computer?
Thx!

r u at home when you are tethering and do you have Bluetooth on your laptop
the option is checked, as i have double checked since you all have suggested this. yes i have bluetooth on my desktop but i would prefer to stay away fromt that option as its slower than usb tethering. the only thing i think may be effecting me that i just htought of was that i have had the usb cable plugged in the front side not on the direct Mobo connection. i will try this tonight and report back any success
I have the same problem, I've tried using the cable that it came with, the cable that came with my htc-6700, and my girlfriends Blackberry cable. It will usually begin to charge while tethered(PDANet) but quickly will revert to the battery. I'm using my girlfriends laptop as mine has a fried harddrive, her power cable jack is loose as if someone pulled the cord hard to the side, this causes it to switch from external power to battery very quckly sometimes. I thought that this caused the problem I had so I didn't bring it up before. I have my phone set to charge when USB is connected and I do not use any USB hubs. I've tried tethering over Wifi but I don't seem to get as high quality of a connection.(Bittorrent speeds extremely slow, although a speed test showed 2134kbps downspeed) I hope this can provide more information to figureout what is causing it.
Try this! Make sure it isn't causing your phone to get to warm and causing this issue, I had a similar problem with wifi and gps usage hmhm,
Open your keyboard whilst it is tethered and see if that makes any difference, and I'm not sure if it is possible to turn the screen off on the phone while tethered, but if you can do it!
Let us know what happens!
Kewlj1313
hmm...i wonder what's causing the power consumption to revert to battery source instead of usb cable. have you tried the dongle that came with the device? It supposedly allows you to charge while saving another usb port for headset...etc. Maybe it's possible to charge via wall charger and tether through usb cable at the same time?
or like previously mentioned, charge via usb cable when it's connected to the computer, but tether using bluetooth. I suspect the data tethering through usb is causing the "charge" to drop.
here is what i have found. First the power source must be sufficent ie 1 amp or 1000 ma use an ipod usb charger for moble htc one for home. Second the dongle will only let you charge on the mini port not the e-mini on the side. Problems iam working on is reducing battery drain by shunting off screen but it doesnt work with usb dun. it does work with wmwifirouter but i think there is a heat issue because it stops charging after awhile. Best sessions i have are usb with battery all way charged bthen watch it with battery window open same time.
criddlem,
THanks for doing the footwork on this one.
Shouldn't the bluetooth 2.0 network connection be capable of up to 3Mbit data rates in one direction? I wonder out loud if anyone on this forum has tested connectivity over BT? I don't know how this is handled in the hardware and it could be that the BT only gets a fraction of that in the real world. Of course, the laptop would have to be BT2.0+EDR as well to get that kind of rate in the first place.
Of course, running yet another device at full pace may just drain the battery that much faster!
Have you tested data rates over both BT and USB?
Thanks!
I tether quite frequently using a USB cable as well and I have found my phone always maintains a charging state. It does seem odd that yours isn't. I do know that I am not using the cable that came with the phone............

I was going to suggest something similar.
A couple of years ago I had a sub-notebook that, for lack of a better term, had "sucky" usb ports. When I measured the current supplied was ~100mA. Enough to trickle charge my old TyTN, so it's amber charge light lit up, and I thought all was good.. till it gave me the ugly "Place on charge to prevent data loss message."
Do you have anything there to measure with?

Hi, sorry I may have misunderstood what you are trying to do, but I bought this cradle on ebay http://cgi.ebay.co.uk/HTC-Touch-Pro...photoQQcmdZViewItemQQ_trksidZp1742.m153.l1262
It has a seperate power in line for charging (including a 3 pin UK plug) and a USB sync line in the back of the device.
I belive this device charges from the mains while being connected via USB to the PC. Of course it could be charging through the USB but for me it charges quickly and is connected to PC at the same time so does what I need.
The swivel to use in landscape is an awesome feature too. Battery for me does run down pretty quick, away from cradle, but then I have been used to previous poor battery performance WM devices.
Cheers, Blair
well Erikr88, u said that u have the option check (to allow a charge while connected to your pc) and that u double checked to make sure. well go back and uncheck it as their is no option to check a box and charge while connected to ur pc. the option u can check is to NOT allow a charge, so uncheck it and c if that corrects the problem.

xda trion problem

Hi, if there was someone who could help me.
My problem is as follow:
My battery isn't charging at all neither through main charger or activsync.
I have been able to sync the phone via cable but not charging. My phone is on at this moment throught activsync
The battery is not recognized by the phone as it shows me under:
Settings
Power
Main battery unknown.
When i try to charge the phone with the supplied charger there is no orange led showing me that it is charging when phone on or switched off.
I was thinking that it could be that it was because my battery was dead but would the indicator says unkown main battery. Thanks in advance

I do believe that for the tab 2 to charge via your computer's usb port, it needs to be off.
Normal usb do only have 5volts to use. And the tab 2 uses more than that when it is on.
i asked myself that when i got mine.
it says "discharging" ans shows an "X" but in fact it DOES charge, but very veeeery slowly. you can leave it plugged for hours and you'll see that. i tend not to charge it via USB but if you will be on the laptop for hours its a good alternative.
my P5100 also doesnt charge from the laptop, same cable that charges from the wall charger i got with the tablet
maybe needs another special usb cable to charge from computers
Thanks for the replies

i remember reading on a site not too long ago trying to figure out this problem myself. they were saying that usb ports are like 500ma and since our tablets have a 4000mah battery. the usb ports dont provide suffient power even with the screens turned off. only way to do it was with the tablet completely off and maybe it would charge. i know when i plug mine into usb it wont charge, even with trying the little trick to it.
The manual states the tab will not charge via USB and the provided wall chargermust be used to charge the tab. USB ports dont provide enough power to run the tab and charge the battery.
