This morning I almost got a shock because my X1 stayed black and seemed to be totally dead. Luckily I soon figured out that the Battery was empty, no currrent left on it to let the device even blink. But what happened? When I went to bed yesterday I connected it to the USB cable and left it charging! Everything seemed the same as all the times before. What may have caused this?
Only things that were diffrent from my usual charging procedure:
The Cable were connected to the PC USB Slot.
I shut the PC (laptop in this case) down but the USB Slots had still power. The charging lights of my X1 followed their normal pattern.
Normally I unplug the power cable from PC to prevent the USB Slots to have power. Because my USB harddisk keeps rotating while having power from the USB.
Normally I charge the X1 directly from the power outlet. X1 turned off.
So this time PC was off. X1 was off. USB Slots still got power. X1 connected with USB Slot. X1 seemed to charge normally.
Well, the result was that my X1's Battery was totally empty the next morning. Obviously instead of charging the USB slot drained of the whole battery power! But note that the charging lights were active as normal and the Battery was still warm in the morning.
Perhaps this helps others to prevent such issues.
you are crazy if you:
1. charges from laptop
2. from powered OFF device
you can repeat this case endless - xperia will be drained

Don't charge it in standby mode, how stupid is that?
What? I don't see any reason not to charge it from a laptop. Even if it's powered off, as long as the USB ports have power (mine has a BIOS setting for this) there is nothing wrong with that.
Also, what does it matter if you're charging the phone powered off or powered on?
On an interesting note, however, the same thing actually happened to me last night.
I plugged the phone into the wall socket to charge it (battery was at about 20%) and I actually saw the battery percentage rise as I was still using the phone. I turned it on in the morning (from standby, not powered off), and as soon as I pulled the power cable it went dead as the battery was completely empty.
I have no idea what might have caused this, and it hasn't happened to me before.
Next time dont power off ur X1,
if same happends then your battery is suffed.

1) This was accidently
2) Why? I dont like it when mobile phones are on standby while I'm asleep. Charging the device when powerd off should make absolute no difference? Worked everytime but the one where it was connected to a powered of laptop.
Why will the Xperia been drained?

Do you mean standby or powered off? Why should it make any difference? And why does the battery getting drained?

What does this BIOS setting say? I assume that my USB slots had too less power when laptop is off. But its very strange that your Device got drained while connected to the wall socket and in Standby mode. Maybe my USB slots were not the cause? Weird ...

It is weird. Since your phone was off I don't think it would use any of its battery power.
I have a ThinkPad, and IIRC the BIOS setting is something like "Always On USB", in the USB settings. With this turned on the laptop will power its USB ports even when turned off, as long as the laptop itself has the power cable connected.

from powered off PC, when power on usb enough to wakeup PC or feed LEDs,
but not to charge another device. in that case power go into the weaker side, means from x1 -> pc
I had this problem too... seems after hard resetting my phone one time, one option was different to normal after I hard reset,
Click on the battery icon at the top of the screen
Theres a tick box, that says:
"When device is turned on, do not charge the battery when connected to the PC."
this was ticked for some reason. Unticked it, and all was fine.
Try it
I noticed this happened to me too for the first time, after i put in the wall charger and the the phone seemed to charge, i found it completely dead after 3 hours and the battery was warm, running a vanilla R1A

Also I think for the X1 to charge- it requires activesync. from my experience, when connected to the pc- without activesync, the X1 would indicate charging- but never actually gets charges. Hence when your notebook is off, activesync obviously wouldn't be running-> no charge either.

I assume a turned off PC would only power its USB port power pins and wouldn't respond to any transmissions on the data pins. So to the phone it should look just the same as if it were connected to the wall charger (just probably with a bit less power).
Also, when I have my phone connected to my laptop through USB Internet Sharing it does actually charge (it doesn't connect to ActiveSync when using Internet Sharing).
The device should charge in any USB mode as the USB port's power pins supply power regardless of the protocol used on the data interface.
Does the X1 have no safety feature that does prevent the battery from being drained?
In my case I assumed it happened because of the USB Port had too less power. But when you turn off your PC (+USB power) and let the X1 connected it would still mean a movement of current from the X1 Battery --> inside the PC as long as they are not on the same potential. If the PC is earthed somewhere (for example connected to the wall socket) the Battery would be drained out totally! They never get to the same potential as long the Battery has power.
As jjm34 mentioned, if the PC is on and USB slots powered normally the X1 should charge in any case.
Maybe this is not the real cause of the problem. People are reporting that the X1 got drained while connected to the wall charger! That's really weird. How can the battery being drained by this? Any suggestions @Ethermind ?

It could be:
It's drawing power FROM your x1 to provide power for laptop internal components.

Mine has. Put it on the wall charger and the charging symbol is there. It reaches 100%, the charging symbol disappears and it shows 100. Then in the morning it's at 90% even though it was still on the wall charger.
I've not left it plugged into a 'running' pc or laptop long enough to see if the phone runs off the battery after it's reached 100%, but it shows the same symptoms. Charging symbol until 100%, then it changes to 100%, no more charging symbol.
Even MSVC stops reporting '% & charging', just reports the % level once it's reached 100%.
I made 2 observations :
It seems the X1 need usb data pins active to charge the battery. The wall plug has something enabled to give power to the data pins (by the way, the wall plug can charge an iPod or an iPhone, it works perfectly). I tried using a cheap wall plug bought in china, no way to charge the X1 or my iPod as there was no power on the data pins. So when connected to an off PC, I'm not sure what's happening. If someone can give a try to analyze this with a multimeter, that would be nice.
It seems also the X1 stop charging after going to 100 %, and won't charge anymore unless you unplug - replug it.
Thanks for your contribution.
Maybe there exists a real hardware failure.
Normally the X1 should charge until the Battery reaches the 100% level. Then there has to be a switch that prevents the Battery from getting overloaded which is good. So charging stops.
The switch blocks charging until you unplug the device once it has reached the full battery level. Thats ok, too. You should not loose much Battery after a full charge and with a device on standby or powered off. And it prevents the Battery getting reloaded at high percentages. Otherwise it would start charging at 99% and stop again at 100 and so on, all the time.
But now assume the switch has sometimes, somehow a failure.
Instead of preventing current to get inside the battery it enables that current can flow into the wall charger.
I do not expect that the current flows into the power outlet. Maybe it gets "lost" in the current transformer that you've plugged into the power outlet (Thats the one you plugged the USB cable in.). Lost means it simply gets warm / hot.
Measuring the current with a Multimeter would be a nice proof. If someone has the technical knowledge and qualification to disassemble the current transformer and the USB cable, you have the go .
I haven't tested it, but I doubt the current flows back into the charger, or back into the USB port on a laptop / pc.
But how does the Battery discharge then? When there is no current flowing out it will stay loaded. (it goes like d(q)/dt+div(j)=0 )
Did you all charge your phone while it is on (standby)? I noticed the same problem when I charged my x1 while it is standby. When I pull the plug from my laptop (I used my laptop for charging, laptop powered on), I get 90% battery life. It seems like there is a switch to cut out the power input if the battery reaches 100% and power the phone from the battery.
Try to charge your phone while it is off. I did it yesterday, and it had stopped charging even before I unplug it from wall output, and I got 100% battery life.
Btw, this is not confirmed yet... it is just based on my experience...
so, here's the problem -
i got HTC sfift, as a gift, and it was used sometime. second time I recharged it - it fails.
as soon as i take out power cable - it goes dead. ok, maybe a second, but it shuts down.
when i load vista, and go in battery info - it says - 1% and charging. and it stays on 1% all the time.
i'm asuming it is faulty battery, but could it be something else ? maybe a power socket ? or maybe those small metal pins beneath the battery, that touch battery and the backside of the shift .. ?
anyone ?
it's the battery. Mine charges up to 50-60% and stays there and the max is slowly decreasing downward ...
My shift can't charge or power up off AC
Hi, I have 2 shifts, and one of them is being funny (and not the funny "ha ha" kind)
The Shift X9500 will not charge off of AC power.
I have done these tests & got these results:
- Battery in & AC plugged in = no charge light comes on & W7 says nothing about charging
- Battery out & AC in = no charge light & W7 says no battery (expected)
- Battery in & AC out = no charge light & W7 says not charging (expected)
I tested AC adapter on a Tekkeon external battery and it charges that external battery so the AC cord works.
A new test was done.
With battery out, and AC cord in, the unit will not turn on
With battery in (and some voltage on battery), and the AC cord in, the unit can turn on, and I can remove the battery (while still on) and the unit remains on, and the battery area says (No battery-AC Power)
So what would make the Shift not turn on with the AC cord in only?
And, what would make the AC cord not charge the battery?
I'm thinking it is related to a fuse/circut protector or something from the AC to the unit, but mostly, why can the Shift "Run on AC, but not turn on with AC only (i.e. requires a battery to turn on)
UPDATE:
I called HTC and the Shift is under warranty so they said to mail it in.
It seems that the issue is mostly eluding to the AC not charging the Battery is causing all the other issues...we will see!
Leaving the Phone in USB Tether mode, it may not charge.
Today my Focus was down to about 20% charge remaining. I hooked it to the computer and it indicated it was charging. I came back a few hours later expecting to see it close to fully charged. It was showing the charge indication, but it was also showing it was almost completely discharged. (The battery icon flips back and forth from the charge icon the the current battery charge icon) I pulled the usb cable and it immediately told me the battery was critically low.
I put the USB cable back in, hooked it to the AC adapter this time and it showed it was again in charge mode.
I opened the diagnostic for the battery, *#2*#, and it showed 4% charge.
I removed the battery and it was not hot. I reinserted the battery and in the past few hours I am showing 67% charge now. I also had left the USB tethering option in there from yesterday, so I set it back to Zune and the phone rebooted for that. The battery is not very warm.
I don't know what to think. It looks like leaving it in USB Tether after i tried that yesterday might have caused it to refuse to take a charge in spite of showing the charge indicator. If anyone else has put theirs in USB Tether and not switched it back to Zune afterwards, I would like to know if it will really charge being left in that USB Tether mode.
Not odd at all. In the past, Samsung WM phones are known to disable charging when in USB modem mode.
My battery dosen't charge anymore.
About one month ago, sometimes when my battery was in 1% I only can charge with cell off and usb pluged in pc. In the wall charger the white led dosen't turn on.
Now, my battery won't charge, I plug in pc and the white led turns on. Sometimes phone turn on and boot normally, but after 2 minutes it turn off.
When is on, battery indicator shows is charging and 4% battery,
I´m using tezet' CM10.
edit: in the last 3 hours i plug in wall charge. screen shows just battery and a interrogation point inside and the white led is off.
Any sugestions?
thanks

Did you try with another battery?
It seems the phone cannot handle it because the circuitry inside the battery may be broken.
Good luck.
i dont know anyone with the same phone.
after changing charging to pc and to wall many times my phone began to charging.
now is working perfectly...
Did you use the same cable for usb and wall connector charging? (cable broken?) Did you try another wall charger? (charging device broken?)

the problem only occur when my phone is 1% charge. After the last problem i can charge my phone without problems.
So you just can't let it get to 1%?

If the battery lower than 15%, it will warn, if lower than 5% it will auto close device. If the battery lower 5% then charge may cannot open device to charge.
