I noticed that when I plug in my NC via. usb cable to my comp. the battery is set automatically to 100% (erroneously) no matter how long the NC is plugged in for (for e.g. it was at 60% or so and I plugged the NC in to transfer a file....which took about 30 sec. and now it's at 100%). Anybody know if there's a fix? I hate having to guess at battery levels after this occurs. Nor do I want to have to fully charge it every time I plug the usb cable into my comp.
TIA

Yeah, a lot of people have noticed this... What you'll see is the next 30-40% drop off very fast in large increments and it eventually settles down to the correct amount. I never plug in my devices to transfer files, I use adb wireless or rsync. If I'm moving large media, I just remove the SD card..

This problem just started last night and I can't figure out what's the cause of it. After a few hours into charging, the phone just turns itself on and charging stops!
I'm running stock rom with a few performance tweaks. I'm not sure whether this's software or hardware related and if a hard reset would fix anything.
Cheers.
Are you charging using a PC or directly from adapter?
if from PC, click on the battery icon when the device is on and make sure that "When device is turned on, do not charge the battery when connected to the PC." is unchecked
I use the adapter to charge, I did try to untick the option afterwards and now just osberving if it does it again.
May be this's another bug when it's supposedly only applicable when charged from USB.
Charging issue and low battery life
Hi, I have had my X1 for 4 days now and overall I am very happy with the features, and I have obtained a lot of very useful tips from the XDA forum, thanks. However I am experiencing problems charging the phone and also not happy with the battery life. Last night I left the phone plugged into the USB of the pc that I installed activesync on (pc was, of course, also on) I switched the phone off and ensured that the charging light indicators were flashing. This morning the charging indicators were off but the phone was only partially charged. I then plugged the usb cable into the mains charger and the phone charged to full in 1.5 hours. Does this mean that charging via the pc is inefficient? During the day I made no calls and sent 2 texts, I did have messenger and skype running although I put the phone into sleep mode. Its now about 8pm and the battery has died. I have plugged the usb into my laptop (which does not have the activesync software on it) the charging lights are flashing but I dont think that the phone is charging as the battery is draining. I read on this forum that you must have activesync installed on the pc that you want to charge the phone on, but why is this. Whats the point of that, the whole point of being able to charge via usb is that you can top up anytime you are near a pc, and looking at the battery life I assume I will need to top up a lot. Can I have your thoughts please.
i have been in the same position.
it's probably because your laptop / pc is in hibernate mode / power saving mode..hence it doesnt charge.
try disabling it and see how it goes
Thanks for the prompt reply Berlinberlin
Hi I can confirm that my PC is set to turn off monitor after 20mins and to never turn off Hard Disks and never go into standby and never hibernate. So I don't think that this is the problem but thanks for your thoughts
How long does/should it take to fully charge the phone via usb? How long does it take yours to charge? Since I wrote the post above I have had my phone plugged into my laptop but with the phone swithed off, the charging indicators lights are pulsating. I have now turned the phone on and the battery is 40% charged from being nearly totally depleted (about one hour of charging) . I do not have Activesync on this pc, so the phone will charge on any PC, I assume.
hello.
once i had one x1 charged via usb over night (with a pc with active sync)
the battery depleted the next morning and it doesnt turn on again
so maybe it's better to quit active sync before charging?

The charging problem I've observed has a different effect:
when on charge using the adaptor, the battery charges OK to full and then charging ceases (as it should do)
BUT
if the X1i is connected to WiFi on my LAN, after a time (maybe 30 mins), it commences to recharge and never stops, so the battery can become dangerously overheated.
Disconnecting from WiFi and soft-reset seems to bring the system back to normal.
At this stage I don't know the root cause, but I have a new battery on order. When this turns up, I'll try the same routine and post results. Obviously, I suspect (hope, too) that the "smarts" in the battery are faulty.
x1 charging problem
I' have the same problem with my x1 charging.
The phone after i started charging, turn on and stop the charging.
In the mornig the battery is low.
Is there any solution that fix the problem?

In your case I tend to think the problem is with Wi-Fi using more battery than what it's gaining through charging. I had similar problem with a generic mini-USB charger. Most charging problems are associated with either battery or charger itself.
Even i had a same issue,
But i luckily remembered the setting which i had changed,
Try this,
Setting`s->System-> Power-> Advanced Tab
{code}
Make sure u have selected this option and set it to minimum value,
"Turn off device if not used for"
{code}
Hope this solves issue
Here's an interesting discovery - would be interested to know if anyone else has the same issue.
Basically, my old WM6.5 phone (Touch Pro) used to take charge from a powered USB socket, even when the computer was turned off.
Plugging the HD7 into the same USB socket, and the phone won't charge. That's fine, I can understand there may be valid reasons for it.
What's *really* interesting is that if I leave the phone plugged into this powered down PC overnight, the battery is pretty much dead in the morning. Compare this to leaving the phone unplugged completely, and I'd generally see 15% battery usage overnight.
The solution is pretty simple - don't leave the phone plugged into this USB socket, but it seems odd.
Any chance someone else can try this?
Is the Zune client on your pc open because my phone will not charge with zune open
but once i exit out of zune on the pc it charges fine...
ive lost my charger and too lazy and cheap to buy a new one so im just using the pc to do it....
no - the PC is actually powered down. However, with soft power switches, the USB port stilll can get power, as proven by my ability to charge my Touch Pro from USB when the PC's off.
I'm not sure what could be causing this, but i will try to see if mine is the same too, then i will post feedback
I've charged mine on a USB port at work, but there isn't any Zune software in the way there... Honestly, I don't sync through USB, so I never noticed this, but at work I have used the USB port on our camera system to charge my phone...
most likely cause is the fact that the computer reduces the amount of current send to the usb port when powered down.
normaly all that is needed is a move of the mouse or a key press to power the computer back on.
now both the keyboard and mouse are low power devices.
now my guess is that the touch pro needs less power in standby then the hd7, and therefore the first will charge and the second will drain.
so to solve this question you need to measure the power comming from the computer in standby (powered on it's 500mA), and both the phones in standby mode.

Here's what I find odd:
The phone will not charge unless powered on. For example, if I have the phone turned off, and plug it into the wall charger it came with, the phone boots up. It will NOT charge while turned off.
Anyone else notice this?

i saw someone mention that the led won't turn on during charging while the phone is turned off.
sadly he didn't wait long enough to see if the led turns on when the battery is fully charged.
also i have no idea which model he was using.

I posted earlier about charging issues on the HD7: http://forum.xda-developers.com/showthread.php?t=849548
What I found was that if you have the HD7 plugged into the USB port and then you suspend/shut down the PC, it'll stop charging (while all other phones I've used - iPhones, HD2, etc. - will keep charging).
Once you suspend/shut down, you need to then unplug and replug the HD7, and it should start charging again. Not sure why this happens, but I need to do it every night, otherwise I have a dead phone in the morning.

That is apparently a "feature" of WP7-- the phone will automatically turn on when plugged in.
Okay, so here is the story, I am without the OEM Nook charger (cable) and it seems that no other charger will charge it, I splurged on the Nook in the first place therefore not having the funds to buy another cable. So what I am asking, is, does anyone else know anyway to charge it?
I got a generic retractable microUSB cable. Charges fine from a computer (albeit more slowly than with the Nook charger). Interestingly, it charges super-fast when plugged into a powered USB hub.

You can charge from a computer? How? I have battery stats pulled up and I watch it as I plug it in, It mounts, but no charging

It is indeed charging when you have it connected to the computer although the amperage isn't great enough to trigger the Nook into a charging state. Keep it there for an hour or so and you'll notice a difference in the battery level.
I would turn off the auto mount of storage when charging from a computer. I charge my nook using USB every day at the office.

No it doesn't, that's a bug. At least if it's what I've seen.... My NC will sometimes to from say 70% to 100% nearly instantly when plugged into the computer. But it doesn't happen every time.. I haven't tried to figure out what makes it happen, but could be related to repeated plugs of the NC to the computer or something, as I was farking around with disabling/enablng automount when I last noticed it happen.
Later it'll start dropping like crazy and recover the "incorrect" charge status back to normal, like 5% drop in seconds several times in an hour is what I have seen it do in the past.
Okay, so if I leave it plugged into the computer, with auto mounting off, it will charge?

Mine does, I started the day @ 75% a few hours later it was fully charged.
I had same problem, bought nc used and got wrong cable
Used nook wall chager with wrong cable and got " not charging" but i left it overnight, next day it still showed same amount of battery it had night before so i thought it didny charge.
Went to buy nc charher $25!!! Ouch. Plugged it in and battery percentage went from 10% to 99% in 1 second
My theory is that a regular usb does charge it but the nook wont recognize it, but the battery is charged

Well, what you describe is not what I've seen.. What I have seen is that it will charge from ANY source, although it does NOT show it on the status bar or in the Settings, but if you watch the charge percentage (I use Battery Snap) you'll see it charging, assuming there isn't much of a load on the NC. As far as I know, it charges at 500mAh unless it has the NC Cable + Charger plugged in.
What I've also seen is that sometimes the charge jumps to 100% for seemingly no reason when plugged into my PC. Doesn't happen all of the time, but it's not charging fast, and it's not a "recognition" thing, it's completely false. If it jumps from 70% to 100%, it's still only 70% charged. It'll "discharge" really fast later, presumably as the system does whatever it does to determine battery charge (battery voltage etc).
Hello there,
Its a but weird but hey this is something very normal for the 2x I think. When I plug in the phone to the pc, this will identify the phone and all that, but it will not charge. I have tried different USB slot and other PCs but nothing happens. On Power the phone will charge as normal. I have also down a calibration of the battery..
Anyone?
I just had the same thing happen to me. I'm glad I read about your wall charger suggestion . Then I read about another person who pulled their battery out and long pressed the power button to clear any risidual charge, I did that and when I turned back on it had gone from 1% to 5%. This was after useing 'battery calibrator' which deletes that file. I also have battery monitor widget and wonder if it conflicts, I think I entered a random number when it asked me the wall chargers ampage. Who knows it charges from computer again. My mother had a problem similar on her nokia, she let the charge get to low and they had to 'shock' the battery into life.
- actually if you have the mode where the screen stays on then the phone might just consume all the power.
-nope, seems wall charger is super fast and computer is slow, maybe usb just doesnt have as many amps
check your usb cable, cheap china cable have problem with charging
I got another cable, GOLD!, and did more testing, its a slow charge on computer and charge goes down when playing counter-strike. Charge goes up on wall socket when playing CS. The charger says it puts out 1A and im sure that more than what my laptop USB puts out, maybe I'll try it with my desktop.. debug mode did nothing to change the effects.
My captivate is starting to refuse to recharge after aound 24hrs or more without being plugged in. If I power off, plug the charger in, then turn it on everything is back to normal. I have tried the Nexus 7 charger, OEM charger and usb computer charging and it refuses to charge if I dont plug it in again within 24 hours or so. Doesn't matter if its still almost full or almost empty. I'm not sure why this happens-tried to google for a solution but couldn't find it.
Im running CM10-M2 if that makes a difference...

Looks like you maay ahve a janky usb connector. Check if any pins are bent or the usb connector is out of shape or damaged.
