Battery drained out totally while connected to PC

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 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...

How to set Legend to not charge while it is connected to USB port?

Hi, do you have any workaround how to set my Legend to not charge the battery while it is connected to PC's USB port?
When I want only to transfer some files to SD card and plug the device into USB, it starts to charge. It is very important for me because it continuously damages battery if this happens several times only for some minutes. In Windows mobile there is a great option to not charge when device is connected to USB. I hope there is an option to do this also on android.

Hmm, on the hand way I am pretty sure that it harms the battery ... 1minute chargings are not good for battery...

I am also certain it DOSEN't damage the batteries...
However.. There are several reasons to disable charging when connection to a PC.
For instance, using a USB hub without additional powers, the drain the phone will put on the hub, will make the rest of the stuff connected to it stop working.
Or simply just to preserve the batteries when using a laptop. The batteries on laptop is bad enough as it is, so no need to put more drain on them...

*replace ! with .

Lithium-based batteries (like those used in basically every single mobile phone now) love to be topped up constantly. In fact, they suffer permanent damage to the lifetime of the battery if they are ever empty. Don't worry about charging them for a few seconds are a few hours, as long as you don't let them go flat.
Lithium batteries will only work best for a few years from the day they are manufactured (not their sale date, by the way). You'll notice if you have an old mobile phone or iPod that they'll start to run low faster and faster the older they get. This is just a consequence of the chemicals they are made of. It's also why some people refuse to buy Lithium-powered devices that don't make it easy to replace the battery (like iPods, for example).
Also, Lithium batteries don't hold their full capacity right away. They have to be charged for 300% of their capacity for them to be running at peak, although you do not need to do this all at once. This is why some devices come with advice that you discharge them completely a few times right at the beginning. I never do this, because as I advised earlier you do not want to let them go flat. Instead, I charge it up to 100%, use the device down to 50%, charge back to 100%, over and over, since each of those charging sessions contributes to the total 300% necessary.
Nickel-Cadmium batteries were the old sort of rechargeable batteries used in other sorts of devices (toys, remote controls, etc). The best care advice for them is to leave them in the charger until they are needed, and use them until they are completely flat before charging again.

[Q] DroidX will only sustain charge level, but not charge up!

I am trying to figure out why my DroidX will not charge fully all of the sudden. I plugged it in yesterday to a wall charger for about 2 hours when the battery was at 50%, can back after 2hrs, and it was still at 50% even though it showed the charging icon the whole time. I rebooted it, and plggeed it into my computer's USB port, and set the USB option to "Charge only". Came back this morning, after it sat there for 6 hours and same thing - it is just maintaining the current battery level, but not charging it higher.
I have only owned it for a week, and the only change between now and when it was charging properly was that I installed a wireless tethering app, however, that runs on demand, and it has not been open or running. WiFi and GPS are also completely turned off.
Anyone else experienced this? I assume unless I keep it plugged in 24/7 now, it will eventually die all the way down!!
p.s. - I also tried letting it charge while it was completely powered off, but same thing. Shows that it is charging but just maintains current level.

this is not normal ,while in the wall charger it should charge all the way and the same on usb but just slower ,if this problem persist i would bring it to VZW and get a knew batt or phone or both since you have only had it a week

It may not be the phone or the battery. It's probably a faulty DC adapter which is not delivering the proper amperage. I just had this problem with my Slingbox. It would light up but the lights looked dim and I couldn't connect to it. A new adapter fixed it.
(Edit) I just reread your post and noticed you are charging it on your PC's USB port. Try the wall charger or another PC. Some PCs don't put out enough juice to charge.

This is somewhat true. The phone should charge with less power regardless of the source. You notice this most on say a USB hard drive and this is why you have y cables sometimes on the drives that take more power. Does the computer you happen to be charging it on happen to be a Laptop?

FYI - I charge from a desktop PC that has a 1000W corsair powersupply and hig end motherboard.
With that asie though, I was able to get the charging back - works fine after I did a hard reset. Most everything was backed up via Google, so all I had to do was rearrange my icons on home screen and change a few android settings.
I still have all the same apps, so I do not know what caused it. Whatever, it is fine now, but if it happens again I will take it in - I do not want to have to hard reset every few weeks. (I have the $6 a month full protection plan, even if I lose it, it gets replaced)

[Q] Overnight: Charging to 100%, then discharging while still connected?

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.

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

Let me explain even better... I can charge my phone in the normal way... but i cant keep charging my phone on usb when i'm using the phone while charging.

Go to settings, about hit the build number 6 times that will activate developer opinions USB debugging is in there

There is probably a hardware connection issue. I believe you don't need a driver just to recharge thru usb. Are you able to make data connection to your pc using usb cable?

Your USB port will charge at a slower rate using PC-USB , if you're tethering the phone is probably discharging faster than the computer is charging - if you're on KK for example screen on will use 1700MHZ if in use so quite a drainer, Failing that, it's possible it's a faulty USB from either the computer or the device.

I'm able to make data conection with my phone and usb...
And like i said, I didn't have this problem until today... I think it coz i install crack app, or put a new sd card.

It's possible they may be causing it, the cracked App could be running anything in the B/G of your device keeping it awake hence USB not charging it as it's in use. Uninstall it (and support the Dev by buying it!!) see if it makes a difference.. Another thing is check your wakelock/battery use.. Media scanner might be eating up your battery.

Already uninstall it, same same.
Probably its Media scanner, coz I put 4.5gb of music and 1gb of photos and videos yesterday... How can i control it ?

You have to let it index the files - it varies on how long it takes, but it should reset OK on your next battery cycle at least.

Index Service and google services are consuming the most of my battery... So I have to w8, correct ? But it takes soh long, like days ?

OK, this is very simple but you need to figure out which of the following problems is yours:
1. phone is not charging at all
2. phone is charging, but at slower rate than it is discharging
1 you can test by noting battery level, shutting it down and let it charge for an hour or two, or even overnight. USB 2 should give you about 400-450 mA, battery has capacity of 3200 mA, so figure in about 8 hrs your batt.should charge from 0% to 100%. or about 10% -15% an hour.
2 you can test by watching how much discharge you have overnight: I normally have 3% -5% discharge over 7-8 hrs night, when phone is not used, but on.
If your phone discharges more than 20-30% overnight, then it will take forever to fully charge and at above about 70% discharge, it will never charge fully, since discharge rate is similar to charge rate. If that was the case you need to find what is responsible for such high discharge rate. As somebody else already mentioned if you're using phone while charging, the screen alone will take as much power as the charge can deliver, so in that case the best you can hope for is slower discharge.

My case is 2. phone is charging, but at slower rate than it is discharging, AND only on USB, on energy socket is totally normal...
I don't know, i wish my phone is indexing, coz yesterday I put tons of pdf, photos, musics and videos, but why it taking so long to index, is it normal?
My problem is so serious that if I put the phone on usb and let it away sleeping, even like that the phone slowly descharges.

Well, maybe this is the answer : http://forum.xda-developers.com/showthread.php?t=2461958
I will wait little longer to see if its continue indexing.

Sorry can''t help much with indexing, it's the first service I shutdown on all my computers and phone as well, I would imagine you have to wait it out until it's finish or root and shut it down, I don't know about you, but I very rarely search my own files, to the point it's not worth it even if the impact of indexing was miniscule. In the meantime can you force shut it down at least when not charging from outlet? Possibly it will restart, even before next boot, but maybe long enough for phone to charge.

Well i fix my problem. But I'm not satisfied.
Wat you need to do is ERASE all your PDF data. PDF files has a king of a problem with indexing on note 3.
Of course if you have a rooted device, you will have more options.
I'm not satisfied because i can't have my pdf classes on my phone, where i like to study. At least all in once.
TY FOR ALL THE CONTRIBUTION.

I think you give up too fast, you bought expensive phone, why not use it to it's full potential? One option would be to root and freeze indexing like I did. I'm not sure if that would disable searching for words all together or just slow it down, but I think that's better than nothing. Another option which I just thought of now, kind of crazy idea, but maybe it would work, rename file extension, instead of file.pdf use something like file.123 or maybe even file extension that should not be indexed like .jpg or .png. Hopefully indexer will not read file header and just skip it. When you need to read it just force open with some pdf reader, no idea if it will work but try. Another way, maybe it won't index compressed files like zip and again I don't use it so don't know how it would work in real life, but just couple ideas to try.
