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?

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'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...
I've noticed that when I leave the phone plugged in overnight it sometimes just seems to stop charging at a random point somewhere throughout the night and I'll wake up with a phone that is only at 80%, 65%, etc.. battery. It isn't fully charging and then just being drained again either, it just randomly stops charging. It will recognize that a charger is plugged in and even says that it is charging but the percentage indicator in the Settings pulldown doesn't move. This doesn't happen every night and it has never happened when I charge the phone during the day. I assume it only happens at night because I'm not at my desk using it. I can also assume that the device isn't taking 8 hours to go from 35% battery to 75%, it doesn't charge that slowly. Any ideas?
P.S Rooted but on stock ROM

Yeah, I have been using the cable that came with it. I've tried two different ones. I will try to see if it happens when charged through wall outlet.
Sorry for double post. Couldn't figure out how to attach image to an edit.
I looked at my battery settings and this is what I noticed. It looks like my phone is charging all the way up during the evening and then draining but the charging isn't kicking back or something. The huge gap in screen on time was when I was sleeping and there was no use of the device but battery is steadily draining.

I had exactly the same problem for one night.
But it can't be a problem with my Notebook because

Probably due to power saving options on your computer, be they USB power saving settings or sleep related. If you want to charge faster you should definitely use the wall charger, USB charging is painfully slow for me... if i am using the device, load can exceed the incoming current and the phone will still discharge. Moral of the story > USB charging = useless.

It really isn't a matter of slow charging. I'm charging it overnight so the speed at which it charges doesn't matter to me. As long as it is charged when I wake up. I've been using the same computer to charge my phones/tablets/cameras for two years and I've never had a problem. I'm not even using the device though, it is at night when I'm sleeping.
I have the same problem all of a sudden. Happened twice in the past week, never happened for months before. I never charge from a computer, always with the provided adapter and cable from the wall. A few hours into the night, before the phone is at 100% (varies from 70-90%), it just stops charging. Battery graph looks very similar to the one in this thread already posted.
I wonder which device switches the current off, the phone, or the wall adapter. I would have guessed the phone, and if that is correct swapping the wall adapter won't do anything.
Or you can use Fast Charge from Google Play and flash Franco Kernel.
Then you'll be able to switch from USB Charge to AC Charge by charging with your computer.
However, the battery will heat and you may consume its life, so do not do that too often, only when necessary if you expect using your phone very long times as i do, i just change phone every 5 years or more, depending of my needs.
Also, i noticed than USB Charging slowing down the charge at around 80%, but still charging, i read with Battery Monitor Widget, and i seen it will gives minus ampere.
I almost forgot, you may also calibrate your battery, the first time, charge it to 100%, then remove the file "batterystats.bin" from /data/system or wipe it threw Recovery, that will ensure you to use your battery to 100% next time.
Mine seems to stop charging at 100% and go back down also. Mine usually is between 95-100% when I wake up though. Is that just how this phone works to protect the battery? I've never noticed this in any other phone I've had.
There seems to be a bug, where if i leave the phone connected overnight on the stock charger and wifi is off when i wake up the battery is at 80% or less. My theory is that as soon as it reaches 100% it stops charging, has anyone experienced this?

This is happening to me as well; I've come to believe it's a faulty charger, actually. Or a charger designed that way. But the charger's fault regardless.
First occasionally, but now for a few nights in a row, I've found a phone plugged in overnight to be at 80% battery in the morning. When I look at the battery graph, it appears to have charged rapidly to 100% (or close-to), then started slowly discharging. However, with the battery use screen open, I also noticed that the status was rapidly changing between "Charging (AC)" and "Not charging", spending most of the time in the not charging state, despite a constant plugged-in icon in the notification area. This behavior persists regardless of wifi state and through many reboots; BUT, it hasn't happened at all yet (with just limited testing) when plugging it in through the adapter for my last phone (an HTC), nor does it happen when charging via USB. I don't know if the LG charger could be designed that way, where it stops when it's full, or if it's just a faulty unit that needs replacing. I'm going to try it on the HTC wall unit overnight tonight to see what happens.

I'm actually having a similar problem... For me I noticed that the screen stays on while the battery is discharging while on AC charging mode so it may be a different issue. It doesn't always happen but when it does, I'll be sitting around 75% when I wake up in the morning.

Turns out this is caused by using a USB extension cable... it would say the phone is charging on AC but there would not be enough current going through. When I plugged the the stock usb cable in to the charger directly, it charged fine.
Hi there,
got a strange problem.
I plug in my N4 in the evening, it is loading up to 100% and there it begins to DISCHARGE (or in other words, stops to hold the battery at 100%) although still connected to the charger. In the morning I unplug the phone and have just around 70% left ... see attached screenshot.
Using stock charger and cable that came with the phone.
I hope this is not intended by Google? Running Android 4.2.1 Stock.
is this the only time it happened?
It is probably because of the charger. They definitely didn't include the best charger out there try another charger, you'll see improvements.

Thanks! Used my equipment (powered USB hub with another micro USB cable) from old phone until yesterday, and read about charging problems when NOT using the charger and cable that came with the N4. To see if that is maybe the problem I therefore unpacked the "stock" cable and charger - but it didn't solve the problem.
The most strange thing is, that it charges perfectly up to 100%! I would expect then that it stops charging to avoid overloading, but that holds the charge level at 100% until unplugged. I think this logic is not within the charger, but controlled by the phone itself (Software / Hardware Unit)?

Have the N4 about 1 week now and I realized this happening at least 4 times now. I'm usually plugging it in every evening and unplug it in the morning.
Its intended as a safety measure so it doesn't over charge when its 100 percent.... It's always been that way

Hmmm ... never experienced this 15 years mobile phones (at least 4 of them using Android and tons of different ROMs ...). What would be the purpose to plug in your phone in at 22pm, stop charging at 1am and begin the fresh day at 7am with again 30% loss of capacity? I would need to carry my charger stuff all day with me ...
As I said, I fully understand that it stops charging at 100% to avoid overloading - and also see the sense in this here -, but usually it should HOLD it at 99-100% until you unplug and not lose capacity while still connected to the charger.
Cheers
did you plug it into a USB hub that was plugged into a computer? that might be your problem. My N4 has issues charging from USB ports... it never holds charge properly.
This happened to me previously, ended up swapping my charger back to my Samsung OEM one and havent had the problem again.
Another time that this could happen is if you're charging via your USB port on your computer and you shutdown your computer which it will still show the charging icon but the status says not charging which could be changed by replugging the phone and/or having BIOS settings that enable usb power draw etc...
Just found this one ... maybe I'm not explaining my case very well, but it seems I am not alone ...

Yesterday I used the wall plug. All the years before I used a SEPARATELY POWERED usb hub. Even if the PC is shut, the hub provides power to the ports. Anyway, it doesn't matter - Charging is working perfectly on wall plug, usb hub, stock cable, non-stock cable ... before reaching 100% and phone disscharges. Picture in 1st post illustrates the disscharge while still "charging" (last bar at the bottom)
it's def. not normal. mine doesn't discharge, it can stay plugged in all night and it'll say 'CHARGED'

Exactly what I would expect! Now that I found the others on code.google.com having the same issue I think there was a batch of devices having it and that I might need to RMA ...
Well the reason why I was mentioning the charger (unless you've tested another one) is because I was using the original LG oem charger and for a while it would give inaccurate readings on multiple occasions. Example being I woke up (used wall charger) and it said 70-80% and the charge icon was still there but on the status it said 'not charging'. Another time was when it said 96%, unplugged and replugged and it charged to 100%. Then I use the phone for a couple of seconds and it drops down percentage again 96%~ and when/if charged it will say 100% again (giving a false reading).
I was thinking it was the cord because I used my bro's LG charger and it charged the phone 96, 97, 98, 99, 100 and not 96 -> 100% therefore the cord may have been the problem. Went back to my Samsung OEM charger and it has been fine since then and never had any discharging.

I'm on 4.2.1 stock yes.
Thing is, that I'm not plugging it out! While being connected it suddenly starts to disscharge - Why the heck would you disscharge when you have a power source connected?! The "event" invoking the disscharge to me is the reach of 100%. Maybe this is a misbehavior of the overloading protection, to stop charging (as intended), but not restarting to charge at lets say 99% or 98% to get back to 100%. This would mean that when I'm using navigation in my car I would need to reconnectfrom time to time to trigger the charging again.

Thing is, that I'm not plugging it out! While being connected it suddenly starts to disscharge - Why the heck would you disscharge when you have a power source connected?! This would mean that when I'm using navigation in my car I would need to reconnect once and then to trigger the charging again.

Yeah I know what you mean but its odd that I had this problem as well but disappeared when I swapped.
As for my USB/PC, that charges when the computer is on and off but when I turn it off, I would have to replug the phone to get it started again as it will have the same "charging icon" w/o it actually charging. My guess is that if the power source loses its power, even if its temporary it will stop charging. But when I using my Skyrocket a few months back I never had to replug the phone onto my computer to get it charging again but I do know that the computer will temporarily cut off power when you shutdown and bring it back to charge plugged devices. (didnt change any power states in BIOS).
So most likely it is something with the phone but it could also be a setting or some software error triggering a fail-safe or something.

I see definitely some issues in the charging logic in both of our cases here. You shouldn't have to replug your phone if you send your PC to sleep, as long as it still outputs the USB power. Since I would not expect the decision to charge or not to charge in the wall plug or in the USB hubs, I can only hope it is not a hardware problem of the charging electonic, but a software problem which could be patched. Also wouldn't I wonder if this has to do with the wireless charging option of the phone ...
come to think of it i had the same problem. charging from the PC when off via USB it would do the same thing as OP. charging through the wall works fine.
Well just found out I am maybe reposting the issue as I didn't find this initially ... similar (or same?) problem described here: http://forum.xda-developers.com/showthread.php?t=2031246
My battery was dead so i wanted to charge it.
But i can't get it to charge anymore and show the charge logo or anything on the display.
I tried normal power button
power button + up or down control key
I had it plugged in now for 5 hours...
Any ideas what it could be?
Sure it ain't your charger? Did you try using different chargers?
Try turning the phone off, then plugging in different chargers while it's off to see if the charging display pops up.

The problem is, i don't have the original charger anymore.
Today i tried with the htc charger and a normal usb-cable with iphone adapter.
Both didn't work.
I additionally tried charging on computer (usb) or direct power source.
I will try another charger.

If you have access to a wireless charger, try that. If i remember correctly, it activates a different charging circuit that can help revive a phone when plugging it in won't.
I unfortunately don't have a wireless-Charger
Yesterday i tried with the Nexus 5 Charger. Didn't work either.
The smartphone doesn't even get warmer. So I think it does nothing...
Maybe try to clear the usb port better?
Habe a lookat the USB port, i Gad the case once, that one oft the 4 contacts oft the port peeled off and wasnt able to connect anything. I was able to put it back in its Position using some time and steady Hands and a microscope
Second, for some people it helps to completely disconnect and reconnect the battery.

try wireless charging if u can lay your hands on it
if no other option mentioned above works,then try to dissemble your phone using various guides available(@ur own risk)
n try to see manually if your battery is showing a voltage change while charging..
hit thanks if this helps u
Update
Wireless Charging isn't a solution for me.
But!
The Phone did some weird things yesterday.
I plugged it in for several hours.
After one hour, the notification led blinked red a couple of times, then the screen came up with the symbol that it is charging.
Then it went black again.
Unfotunately nothing more possible.
The back was getting warm, so i think the battery was definitely charging.
Any ideas?
