Hello all,

I've seen this issue mentioned in different forms  in different places but with no good explanation / resolution.

The issue:

Omnia warned on low batt. I plugged it in an USB2 slot (via the supplied cable; I tried w/ another USB cable but same prblm) and assumed it will charge that way -- the red LED, batti and S2U2 showed that at least.

However, the phone died on me instead, and refuses to start (on low batt reasons I guess) -- no charging LED light, nothing.  So now I'm left stranded with a dead battery away from the wall charger.

Excuse my french, but .... WTF is _that_ about  ?!?

ROM is DXHH1 as per this forum.

TIA for prompt help, suggestions

Florian

That because it didn't actually charge from USB port, but just falsely indicated that it did.

This is known issue, not sure if it was fixed with latest firmware. I was never able to actually obtain the green light (the only true sign of charged battery) while charging from USB port.

when you have active sync connected.. it doesnt charge...... try  Connection settings/Allow USB connections Untick.. it will charge............. when it is active sync or it sucks battery ...NOT charging..FYI not fixed with the lastest firmware either DXHI1

Thanks for that.
Can someone confirm if any of the newer ROM version address that -- e.g. DXHI1 ? Thx.

it DOES charge via USB when connected via ActiveSync, albeit very slowly

[Ingvarr]

Were you actually able to obtain a steady green light while "charging" via ActiveSync?
Because it will even update battery indicator numbers up, when actual (and not visible) battery charge will go down until phone will just die from lack of juice.

Mine did not work, but now it does.  I am not sure what specifically fixed it, but here are some settings/changes:
- Installed DXHI1 ROM (was on DXHH3)
- USB to PC Advanced connections (RNDIS) On
- Using Windows Vista with mobility center installed from the Samsung Disk
   - It says updated drivers when I look at programs/features
My device does not get as Hot as it used to when pluged in
When it goes into standby when connected, the vista mobile device windows goes away

That doesn't make sense: I had some battery left when I plugged it (though very little) but soon after it died. If what you state is true, the USB connection should at least have kept the device alive... Now the device dead (and not starting or charging) disregarding if ActiveSync is enabled on USB or not

I guess, what it may do is trickle charge, but if you are running things like wifi/bluetooth/3g etc, then it may use more battery than is actually being charged!

[Ingvarr]

Nobody yet actually reported to obtain a solid green light after USB "charging".
I myself has left my i900 on USB charge overnight, and still no luck. It wasnt doing anything, so argument with "too much load" does not stand. Also I was able to charge different 1600Mah PDA from the same port in couple hours, so it defenitely has enough power.

The solid green light shows when the battery reports that its actually 100% charged. This is hardware-based and only reliable indication that it was actually charging the battery.

The battery percentage and charging indicator on Omnia seem to be completely software-based and buggy, so it can report apparent charge increase without actual battery charging (just because buggy indicator monitor thinks that battery is charging now, so it thinks, it must be increasing).

OK, I'm still confused: While the buggy battery indicator might get fixed by firmware, why the hell has charging to do with it ? Again, not only charging, but _discharing_ while USB connected -- again, I was not doing _anything_ with the device while it was USB connected, so it should _at_least_ kept it alive....

Grmble, grmble.

[Ingvarr]

Actually it looks almost like that indicator *assumption* is correct (assuming that it should charge with USB connected).

But the actual charge gate is not opening on USB connection, so device is not actually getting juice and not charging (not even uses external power to run). I hope this can be fixed via software fix and not actual charging circuit hardware problem.

check you USB port if its 500 mah or 200 mah, some pc with USB port have lower ampere in front.

your phone can be using more energy that it can actually get from the USB port, hence it runs out of juice.

[Ingvarr]

Read the thread, my usb port is 500Mah, and it still doesn't help (and only for Omnia, other no less powerful device was charged just ok).

Is there any way to decide one or the other ? If it's a issue fixable in firmware I can (sort of) live with until it's fixed, but if it's a hw issue then it's really inexcusable and we're SOL (s*t out of luck)

Can someone please confirm if this is specific to Omnia or are there out there other Samsung devices (F480 ? D900 ?) with same/similar issue ?

Not having used it on the Omnia (but on the Kaiser and Hermes before I had it) I wonder if BatteryStatus might give you an indication - should be able to show the drain. If the figure is not positive when tethered then the USB charging isn't working or not supplying enough juice (which an untethered figure should give a comparison against).

And before anyone says anything about today screens it would just be a test right?

[Ingvarr]

I guess most proper way will be using monitor *#0228# menu

It reports the current battery voltage. So if voltage not raised after "usb charge" - it did not charge. Well, as long as this voltage is reported correctly and bug is not actually at this part

i'm on hh3, using usb with active sync, 0228 menu shows the voltage hovering between 4.147-4.162, on the charger is goes upto 4.2, i think usb does charge it (at least on hh3) but doesnt quite top off the charge like the charger does

Checking voltage while charger connected is useless, it wont report correct one (it's not the battery voltage in any case, as battery voltage should be about 3.8)

Voltage should be checked before charger was connected and then after charger was disconnected. If it will go up, the battery received some charge.
