I mean if you hook up the usb cable to the separate docking station for the spare battery. My USB cable will charge the phone but will not charge the spare battery

I've had problems with this too. I reckon the phone doesn't charge over USB because the screen is always on (as mentioned in this post earlier) when connected to active sync. Thing is, if you turn the screen off (using power button) then the phone disconnects from active sync and stops charging! It's a no win situation.

I've got round this by installing a programme called ActiveSyncToggle on the PC. It allows you enable/disable active sync. With active sync disabled the phone will charge over USB because the screen dosn't come on when connected to the computer. Of course, the phone dons't sync, but for me that's not an issue as i prefer to sync over GPRS anyway....

Hopefully some of you guys will find this useful.

Actory .. what OS are you running on in your PC? I had the same problem recently and I'm using Win XP SP3 in the office and Vista SP1 at home. I discovered that if you go under Connections tab in Settings, unclick the "Enable advanced network functionality" option in USB to PC, this will ensure the i780 is charged whenever I sync it.

Previously it would only charge on my Vista (running on Windows Mobile Device Centre) while XP (running on version 4.5) would not charge.

Hope this helps.

As the rest of you I'm having this charging problem too.

My PC is Vista SP1 (using WMDC) and I've tried the unclicking the "Enable advanced network functionality" option mentioned above and turning the screen off (mentioned earlier in this thread), but all to no avail.

The charger charges the battery quite quickly (more so than other mobiles) so I'm not sure about the 700mA thing (as opposed to USB only offering 500mA) and all of the HTC chargers I've got are all rated at 1A (implying HTC devices need an even more powerfull charge) but all HTC devices charge fine from the USB port.

I have a number of Samsung Windows mobile devices here and all others charge from USB and all of them came with 700mA chargers - More evidence that this is a red herring?

I've also noticed that the individual proprietary USB connection cables supplied with the Samsung devices have different part codes on them (though I can't find one that works!). I have:

Model No.: APCB20UBC, Serial No.: DK1PB07TS G
Model No.: APCB20UBC, Serial No.: DK1P916TS/7-G
Model No.: APCBS10UBN, Serial No.:DW1Q410AS G

When connected from all cables, the i780 says it's charging (though the amount of charge never increases), but as soon as it's disconnected from the PC the amount of charge plummets as if it's not been charging at all. Clearly when connected to the PC the device is taking even more power than usual as it's running software and services that are only used when connected to the PC (USB, TCP/IP etc.).

This is a right royal pain in the butt and the only WM device that I have ever encountered this on (and we have a large number here in the office). It's getting to the point of being worth a call to Samsung!

Andy.

hi guys,

my first post here.

allow me to share with you my observation on the 3 WM 6 and 2 WM 5 phones that I owned in the last 10 months.

In WM5 phones, I never have any problem with charging, be it a sync-and-charge USB cable, or a charge-only cable. I can plug it to a self-powered USB, a USB-based wall charger, a laptop, a USB-based car-charger, and everything charge very well, and the phones did get charged from e.g. 50% to 100%.

However, for all the WM6 phones I come across (Q9h, ipaq 612 and samsung i780), none of them would have the same charging behaviour as what I encountered in the WM5 days.

The following are consistent across all the WM6 phones (standard and professional)

1. Charge+Sync cable will charge the phone only when the laptop is powered on, but very very slowly.

2. ChargE+Sync cable will not charge the phone from the same wall charger, car charger, or self-powered charger that I used previously on WM5 phones. In most cases, the phone would detect a power input, but charge icon never show up.

3. Only charge-only cable can charge from the same wall charger, car charger or self-powered USB port that couldn't charge in the scenario #2.

My take is that for WM6 phones, the charging mechanism is more sensitive to the power cable grade, and assume the same grade of cable is being used for both sync+charge and charge-only cables, the charge-only cable would be able to carry more current with least resistance overall, supplying the necessary power to charge the phone. (imagine a sync+charge has the same amount of copper wires split over 4 pin, versus 2 pin for charge-only cable)

my point? buy a charge-only cable if you want to really charge from any place other than your desktop/laptop.

I've tried several USB leads and car adapters but they all work the same as on the PC - i.e. they only put any charge in when the phone is on standby.
In all cases, the red light was on, and WM was indicating it was connected to external power and charging.
But hardly any charge seems to go in at all (I've never achieved the magic green light), and worse still, if GPS is on, the battery drains quite quickly.
Defeats the whole object if you get to your destination and find your phone battery is flat!

The same leads work perfectly on other HTC and i-Mate devices - even with GPS running.

Anyone tried the "official" dedicated car charger lead, or found another lead which will actually top up the Samsung properly while doing in car SatNav?

see above.

get a charge-only cable, it'll work with any cigarette lighter charger that accepts USB cable.

I solved the problem almost the same way.

In activesync i just switched off "allow USB connections" in "connectionsproperties". Then the phone doesn't sync, but it still charges.

Hmm...I think we're all missing the point here.

Windows Mobile devices charge when connected to USB.

They might charge slowly if there isn't alot of current from the port, but the do carge dather than discharge at an increased rate. If syncing causes the device to drain quickly to the point where you have to disallow that synchronisation then there's something wrong.

I called Samsung support in the UK and they indicated that they had i780's that did charge through USB (albeit sloooowly) and that if the device actually drained through a USB connection then there was a software/device fault and I should get back to my phone supplier (Orange say that they can't be respnsible for USB charging faulty or otherwise - boo)!

Think that if the battery for the device is a 1480mAh and that can run the device for a couple of days (I'm getting 2-3 days of general use between charges and only going to 30-40% battery in between), that would imply that general consumption of power is much less than 500mAh or the battery would be pretty flat pretty quickly under normal use.

It would then follow that when connected to USB that is giving 500mA and the device reports that it is charging it would subsequently allow more processor heavy tasks (like syncing down a USB cable) to take place giving a load on the whole system that is greater than that of normal standby and general use, but do remember that it (thinks it) has an extra 500mA to play with.

However, what I'm seeing is that when you connect the device to USB the battery drains very quickly. I can only assume that though the device says that the battery is charging, it isn't and that the procesor is told that it can go into higer power consumption mode and subsequently the battery drains within a few hours. What I'm saying is that there MUST be a fault in the device that means the 500mA from the USB port isn't being used!

Perhaps that the 500mA is enough to trick the OS into thinking it can charge, but the device actually won't charge unless it has the full 700mA that the charger can offer. The i780 does charge quickly when it's using the mains charger implying it can use the full 700mA but can't charge slowly from USB indicating a shortfallin the charging system - a fault on the device!

Andy.

p.s. sorry for a rambling post, but I knew what I was thinking when I started!

Nice one dolpher, that's sorted it for me too! Good work!

I had this "problem" only the first day. For a reason I can't tell, it did synchronize but it did not charge via the standard-supplied USB Cable.
The next day, surprise, it worked, even when I use the USB Cable at my USB Charger in the car (which I used for another USB-USB cable before, just now with the USB-Samsung cable).
So for me, it works all fine right now. Just bought 2 more such USB-Samsung Cables for travelling.

Have the feeling as if in the very beginning something may have been on the cable which "worked itself off" after a few connects ...?? just a "wild guess"

Greetings
