Hey guys,
I'm having an interesting issue here, basically I've noticed my vibrant isn't charging the phone battery,
instead it says "discharging" when plugging it in. When i go to the 'about phone - status area'.
When I unplug the charger it says "not charging" and when I plug it in it says Discharging.
Has anyone seen this behavior on their phones? I'm not sure if there is something wrong with my phone
or if Samsung tries to regulate the battery reconditioning it?.
I would like to avoid having to return my phone if this is some sort of strange issue with the vibrant.
I have had the vibrant for over a week now, have not done any changes to it other then simply rooting it,
no flashing done otherwise. I just happened to notice this tonight before going to bed.
Also note that I do not have wifi turned on, and I wasn't running anything at the time either that should be
draining it more then a charger should put out. I have also tried charging it using the charger that came with
the vibrant and a second charger I bought.
I have only seen one post related to this on Google.
http://forum.androidcentral.com/t-mobile-vibrant/33383-battery-discharging-error.html
Update: I can tell you that my % has gone down, from 30% to now 20%, still discharging..
Also Screen Brightness is set to lowest, WiFi Off, and not running any applications in the background,
on original vibrant rom.
Video Or it Didn't Happen, Posted.
Here I took a video of it too if for some reason you can't see what i'm saying, or think i'm crazy.
Weird Camera is angle is cause the phone number just happens to be right under the battery status.
http://www.youtube.com/watch?v=Nk_JHdlMVbg
what charger are you using? and do you have another that you can test? Also if you're charging VIA usb port on your laptop have you installed the samsung drivers, if not install the samsung USB drivers, if you have then try a different USB port.
its doubtful its the phone, far more likely the USB port, charger or cable
I have charged it with 3 different chargers, and cables from different computers and usb ports, as well as in wall charger,
the samsung usb drivers are installed and i'm able to access adb.
My computer also has 3 powered usb hubs.
The battery kept draining, till the phone shut off and restarted on its own
after receiving a charge from the charger, so i'm wondering if maybe some
other people might be able to notice this behavior at all.
When it restarted on its own it said it had 60% battery from 0% right before charging,
so I am wondering if perhaps some people's phones are doing this in the middle of the night.
After restarting the phone charges normally starting at a really high %.
Could this be caused by software problems on the phone.
that is crazy... you certainly have ruled out a charger problem.
Was this just a one time thing and after the restart it's charging normally?
if it's still acting up you could try flashing the original rom via odin or to be safe take it back and exchange it.
People might not be realizing theres a discharging problem
Yeah has only happened once that I've caught so far, so thats why i'm trying to raise a little bit of awareness,
seeing that other post on androidcentral it seems like some people got to be having this problem.
Maybe they just don't realize it. Its not something you'd notice plugging the phone in before bed.
For now it seems fine after a restart, its possible that its a problem that occurs after the phone has been on for so many hours,
and perhaps a memory leak occurs of some sort. It could even be Samsung's poor attempt trying to recondition the battery somehow.
I have had some odd occurrences where I have grabbed my phone off the charger first thing in the morning and found it around 30%. Rebooted it and it charged normally. I think this has happened twice now. I didnt notice anything while I had it plugged in so I can't say if it said discharging or not.
Maybe what you could do is go to the phone settings, scroll to the about section and check out the battery status next time that happens.
On the larger scale of things, this could be a fairly common issue that noone
is taking a look at.
It could be related to why some people are having very poor battery life
and why the battery meter can be really inaccurate.
If your phone discharges itself completely, reboots thinking its at 60% battery life,
I can see that causing many problems that you just wouldn't see since people
just plug their phone in and go to bed.
Bump cause I'm having the same issues. Was a solution ever found for this?
I had this problem before but it happened to me with an after market battery, once I changed batterys the problem went away. so basically your battery is bad..
Yes! I have this problem all the time. A restart will fix it but often I will plug it into a wall charger or car charger and my Battery Indicator Pro will say "failure". Battery life is also horrible.

This is caused by running 2.2.1 roms I think. Only got it once and was on such a rom. A restart will fix it. Its possible you didn't flash good as I have never gotten it since. Its a rom issue though.

Op was running stock rom.
You need to delete your battery stats, but to do this you need to be rooted.Looks like your phone is not charging at all .... plug the charger in and take out the battery and see if it starts charging.... hope this helps ....
this is happening to me, right now. i've had it happen once before, i shut down, pulled the battery, replaced it and booted. it charged fine afterwards. but i don't want that as an answer.
mine is at 84 hours uptime, i don't remember what it was last time i had this issue. whats weird is i was just charging at work not 30 minutes before i got home and plugged it in to charge. worked fine half an hour ago. but not now.
i've got a stock vibrant on 2.2. wonder what's causing this.
This happened to me and i could only get it to charge by rebooting it. I eventually had to replace my phone because it also was doing soft reboots too but discharging also.
I think I found a solution. Is anyone still having this issue tho? If so ill post it.

I have this problem and have been for a while. Will you post the solution please?
Thanks in advance.
here too... but with a htc wildfire (aka buzz)
it discharges while in charge
very strange!
I tried almost everything, also replaced battery with another one original of course... nothing changes, also replaced AC charger... nothing!! my mobile become a fix line
unluckily I don't have a rooted phone so it's not possible for me to recalibrate trough SW
ive had a battery issue similar to this. my battery never discharged while plugged in, but after flashing a 2.2.1 rom(bi-winning) and then installing "battery left" and reconditioning my battery, the "battery left" app had a roughly 18% difference in battery charged then the system...as the syatem read the battery as being lower then the app showed i had. it would shut off with "low battery" when the app said i had about18% left. after flashing again and reconditioning my battery again the problem went away...could be some software setting somewhere!
Just rooted, overclocked, now when i power off it simply turns on 2 sec after.
How come? Anyone know?
Reflash your kernel, see if it continues.

Pulled my battery to shut it off.
Started the phone, shut it off, and it stayed off. Weird!
Thanks for your help.
its not off, it's underclocked so low it can't even wake up the screen, higher your min clock speed to 600 and see if it still happens, of try removing setcpu or that other one that starts with a T.. whichever you use

I have the same problem, instead of switching off it just reboots, even if I power off from recovery.
What kernel are you using. I'm using Ninphetamine 2.0.5, with VillainROM 2.4.2, with Black Android Theme.
I'd rather not pull the battery, after seeing how flimsy the battery cover when I put it on first, I decided I'd try to avoid fiddling with it if at all possible

Well let me tell you about a little secret: if you hold the power button for 10 seconds the phone will shutdown instantly no matter what.
I have the same problem too, it's very frustrating...

Doesn't work: it turns off, stays off for 2 seconds en boots up again.
I got same problem. Never flashed, never rooted. Got original 2.3.3.
I think I#ll try to flash it to fix it.
got a similar problem. probably not related. after unplugging it from a full charge, the phone kept making the "USB connected" sound. when turned off, it would do one of two things: display the big battery charging indicator while flashing the overheat indicator or turn itself back on.
while powered on, the battery icon will change from charging to not charging. I checked the USB socket and doesn't seem to be malfunctioning and there isn't anything shorting out the contacts. so far now, the battery level is at 87 percent after 48 minutes not in use. and now it's not making the sound anymore. I suppose the battery is malfunctioning.

I got a mixed-up thing of the issues on this topic..
When I take off the power socket, the symbol that shows "charging" remains there, and also, it is completely impossible to turn off the phone..
Whenever I turn it off, hard, or standard mode, it turns on again after 2 seconds..
And even if I remove the battery, I put it on again, and then it's back on in 3 sec....
Uh, and when I plug the charger in, when the battery is completely discharged, I have to take it out and back in , several times, before anything appears on screen, and even when it does, there is a temperature warning sign , and a yellow one which usually appear...
I'm getting very frustrated since I just paid 5000 nok (920 USD) for this phone..
And while I really begun to like Android, I guess I'll have to switch back to iPhone with a 4S, or to some better android device, since yes, the gs2 is cool , but I can't stand such issues, since I do run business things, and the phone is of vital importance for me, and not just a console/browsing crap.
Has anyone got any solution on this issue?
It would be crap if I had to send it to service, since it would take a lot of time, and I would have then to buy another temporary phone in the meanwhile...
PLEASE, HELP!
I had this problem, i cleaned the USB port out but that didn't stop it, but i think it helped. I then drained the battery to nothing and it has now stoppped. It's a battery problem, as it didn't switch off like it does when it hits low battery it just died. The battery readings were also inacurrate and every now and then it would do a weird thing like flashing it was charging, but it wasn't. I tried software etc.. and clean wipe before i tried the hardware, so it wasn't the rom i was running. I think the battery is on it's way out, so I've bought a new one.

Did this actually help? I had all the symptoms everyone has been describing and sent it to Samsung for repair. Their response was that the phone was stuck trying to download a PRL update, but as soon as I got the phone back from them and charged my battery to 100%, removing the phone from the charger caused everything to start again. I'm not entirely sure it is the battery, but have no other ideas.
USB charging port is dead.
Buy a new one on ebay and replace it.

Hi all.
Had similar problems about one month after getting my s2. I have unlocked sim card, rooted it and flashed some kernel, shyah i think. And left it with stock rom (Android 4.0). As it was under warranty i reverted completely to stock and took it to the carrier. After one day got it back but they said it had no problem. The fact is that i could in fact turn it off again. After a few days it was back so i flashed a custom rom (resurrection remix at that time) and never had it again.
Now I'm with alliancerom and apolo kernel for a few months and never had it again.
Hello everyone,
My sgh i777 (running one of the UCLE5 semi v# ROMS, can't remember which one xD, on siyah v3.4.3) is having a strange problem. What happened was, I put my phone on the charger on my desk, and my sister had a friend over and were messing around. Well I found my phone later in the day on the floor, and it seemed like it was more scratched then. It was still plugged into the charger at the time so I tried to turn it on. However, when I turn it on, the grey battery screen with the loading circle shows up for less than a second, and the screen turns off. Then it will do that again, flashing this screen until I unplug it from the charger. Not matter what I do, it will not get past this screen, and actually, after the screen flashes a bunch of times, you wil stop seeing the battery screen but merely a flash of light on the touchkeys and maybe the screen. I am pretty sure it is not a problem with the charger itself, and I think it may be a problem with the battery. However, my friend had an issue with his Droid (first one) where the charging port on the phone was broken and he had to use an external battery charger to charge the battery, and then it would work fine. To me, the port seems like it is not damaged, and since when I found my phone on the floor it was really hot, I really think the battery just died. I am also fairly certain that this problem is not a software issue, considering I have not tweaked anything on my phone for a few days now, and since it was working just fine before I found it on the floor. I would appreciate any feedback that you guys can give me because, like everyone else, this phone is my baby
Thanks!

Try pulling battery for a few. put it back in. try to get into CWM and wipe cache and dalvik.
Who knows how that happened. But if you have CWM or D/L mode, your fine.
I had this exact same problem on my phone (minus ending up on the floor part). I think it is from the battery overheating. Pull the battery and let it sit for a few. I had to let mine sit out for almost 4 hours before it turned back on. It may not take that long but i would leave it out for at least an hour or 2.
Thanks for your feedback! Yeah I left the battery out of the phone overnight and when I woke up I tried it again and it still did the same thing :/
I want to get an extended battery anyway (I think I'm going to order the qcell one) and if that fixes the problem that'd be great, but if it isn't a battery problem and it could be fixed now I would love to hear how so I am not out a phone until the new battery arrives ;D
Will your phone turn on when not plugged in?

No it won't even show the battery screen when it isn't plugged in. It only does that with the charger. Also it won't even have the flicker of the touchkeys, just nothing haha.
Try to get another fully charged battery from a friend and see if phone will turn on, or if you have an external charger, charge up a battery and see if it turns on

Ok I will try that as soon as possible
I tried a different battery from a different phone (although it was still a samsung phone and the battery fit right and everything) and the same thing happened >,< nothing would happen unplugged, but as soon as I put it on the charger, the touchkeys would flash, and the screen would flicker at certain intervals. Unfortunately I think this is a more serious problem :/

Same happen with my friend I9100. Power Controller gone. Only service center will help.
Seems like your USB ports are bridged. I had this exact problem. If you're under Samsung's warranty, send it to them and they'll replace it. If not, MobileTechVideos could fix it for you.... Though if you're on a custom ROM then I assume you must put it to stock before sending it out to Samsung...
I got it to work haha. Go figure the one thing I did not try fixed it. -___- I was reading through some other threads and found a guy with a similar problem and he said that he left the battery IN the phone but left it UNPLUGGED. Well I did this overnight and sure enough this morning it worked xD
Reading is wonderful!
Glad you got the problem resolved.

mine was unused for a few weeks too. I thinking its just the battery might actually go to a battery store in my city to get a new one.
I have a Nook Tablet (NT) that is rooted and running CM 10.2. All was well until recently when I noticed that once the battery is drained it'll take almost a day for it to turn back on, most of the time being stuck in a loop where the "battery is too low to power on" screen will appear and reappear. Two days my daughter was using it to watch Netflix and the low battery toast appeared, she plugged it in and the NT shut off. Pressing the power button produced nothing until we unplugged it again. I tried using three different cords including a fastboot cord I made for our KFHD, each time it shut right off and won't start back up. I've tried plugging a cord in without any power and it doesn't have any effect, yet the minute any kind of power is introduced....it shuts off and stays off while plugged in.
I searched Google, read almost every sorta relevant post and have searched other forums as well with no luck. Has anyone had this problem? Has anyone solved it? What could be the problem? Any help is appreciated. :crying:

I have a hunch the battery is starting to fail. It is not a good idea to let the battery get too low, the reason being if it does then the circuity inside tells the nook that the battery is too low to function. When that happens the nook won't power on OR charge quickly. It can only trickle charge, which is why it can take a long long long time to get enough power to turn on.
If this is happening without warning, then it is because the battery indicator calibration is off. If it does flash up a battery warning turn it off right THEN (put it to sleep by pressing the power button once) and plug it in. This should keep it from powering off totally and should charge quickly.
If it keeps happening, it could be the battery needs to be replaced. There are two places to get one that I know of batteryship.com and newpower99.com both seem to come with tools to do the job.
My tablet started doing the odd phantom touches when the battery gets below 23%. I am trying to find a (real) way to calibrate it, but so far no go. But if need be I can just plug it in at 25% or so, as long as it doesn't get any worse. However from what I hear they often do.

The problem you experienced with NT CM flaky battery reading and with NT going beserk at low battery reading was discussed at http://forum.xda-developers.com/showthread.php?t=2551512.
FWIW there are some battery-calibration apps but I have not tried them.
I'm starting to think it's a hardware issue. I have replaced the battery twice and did a clean install of liquid smooth and it still shuts off completely when it gets plugged in. It will fully charge while plugged in but it will not turn on at all while power is going to the battery through USB. Once unplugged it will boot normally. Really strange.

At first I wondered about this being a smaller battery if it would run down fast. It doesn't !!! Works very well !!!
I changed out my battery with one from the above site, but now every time I plug a USB cable in it to charge it immediately shuts off. Anyone have any ideas what could cause this? Wonder if I got a bad battery..

That could be a bad/shorted battery. Mine is still going strong! I would try and reverse everything and start over. When I did mine my vol controls didn't work. Didn't have the connector snapped down good enough
I was looking at this one (still am actually although the one you got is cheaper):
https://www.youtube.com/watch?v=3F0glSyvj2s
http://www.newpower99.com/Barnes_No...cement_Kit_p/barnes and noble nook tablet.htm
I am still trying to see if there is a setting that somehow caused my NT to freak out when the battery reaches 23%
But I have this bad feeling I will need to purchase a new battery. By the way, if the nook just shuts off watch the screen closely it usually says "battery too low" for a second before switching off. And if that is the case after plugging it in, you likely have a bad one and I would call the company to get a replacement.
I have been looking around and the only new replacement batteries I find are the two mentioned and both are 3200mh rather than 4000 of the original. How is your battery life since you changed it? Seems like it should be 1/4th what we had when new (or close to it). Or don't you really notice at this point? I have thought about ebay but then they are used batteries and you have no idea how many cycles are left, and likely hold 1/4th less anyway due to their age. *shurgs* not sure which way to go. As of now I am still having a "freak out" situation at about 23% (roughly). If it doesn't get any worse I can live with that, but from what I have read it will only get worse. :/
Anyone know of a battery app I could use to "adjust" the shut down threashold? I have one that will alert me to whatever I set so if I am not watching it will warn me so that will work if I don't have one that will actually shut it down. I know the "calibrating" apps don't do anything except delete the one file that is only usage stats from the last time it was plugged in, so I don't think there is a real way to calibrate it.
Update:
And on another note with the "spare parts" app the 'battery history' option errors with "the application spare parts ) process.com.andriod.spare_parts_ has topped unexpectedly, please try again." Is this normal? It is version 2.3.7. NT Hidden Settings app application settings/battery use works fine and shows the amount of everything that has used the battery since it was last plugged in/charged. Could this error be a sign of the problem with the phantom touches and inaccurate battery display? And if it is a sign of something broken, what and how do I fix it?
I received a replacement battery and it is doing the same thing, so somehow during the battery switch something got wonkey with my nook. It charges OK just powers off to do it. Since it's used by my kids now it's not essential to be on while charging, but I'd still like to figure this out.

Which battery did you get? And very strange it shuts off when you plug it in. Never seen or heard of that before. It should boot up if off. Or do you mean the screen goes off/goes to sleep but not full shut down when you plug it in? If it is going to sleep, that is likely a app or setting that is doing it. Not sure which but you might want to check any battery apps you have or your settings. It would also depend on which ROM you are running, stock (which I am running) or something else.
Both batteries were the one mentioned in the original post. It doesn't go to sleep when I plug it in, it completely shuts off like no power at all. It will not boot up until I unplug the USB from a power source, although it will fully charge while it is plugged in. I've never seen anything like this and I've been messing with android since my original moto droid 1.

Very strange indeed. The only thing I would say to do is turn the USB debugging on and off a few times, to see if that makes a difference. It shouldn't but if you tried two different brands of battery, sounds like it is the hardware on the nook. But that is one really weird bug.
Something interesting I discovered. While I did get a new battery, I decided to do some experimenting. Researching this issue a lot of people said you need to delete the "battery file". There even use to be a option in CWM to remove this file. The thing is the file is deleted every time you plug in the device. So that is not going to help.
Further digging found that some devices you need to plug them in and let them charge. Or run them down for say 20-30 minutes without sleeping then plug in and let it charge fully. For some devices this "resets" the battery management system.
What I found in my tests is the battery gets harder to charge with age. While the little n light might show green, it is likely only 80% charge sometimes 90%. And it takes awhile for it to really get to 100%. What I did was let it charge up to that full 100% which may take hours. I got a nice battery app that alerts me when it gets below 25% after that things can get crazy with phantom touches. I also have it set to give a audio alert when it reaches 100%, this way I know when it is fully charged.
I know the charge it fully (when it actually says 100% and I get a audio alert when this happens) before 50% or so has helped a lot. At one point the phantom touches started to happen at higher than 25% reaching almost 35%, last time I did a test to see when phantom touches started was 17% so it is much better. Not to the level when I bought the device, but still very useable.
I will put in the new battery sometime I am sure as it is taking longer and longer to reach the full 100% (but that is normal for lithium ion batteries.) it is certainly useable in this state and the phantom touch issue is not getting worse. I think the biggest issue was charging it until the n light went green and as the battery ages, the battery manger gets thrown off for some reason and charging to the true 100% helps recalibrate it.
Therefore I would run it for 20 minutes without letting it go to sleep, then charge until it is really full (usually leave it plugged in overnight and that should do it). Do this a few times and see if the battery is better.
Oh another thing I did. Power it off fully (hold down power button then tap shutoff) then plug it in to charge. Let the charger wake, reboot, and charge the device. This I also think helps recalibrate the system. Although I never did it when I ran it for 20 minutes then charged to full. But I am sure powering off then plugging in to charge at times made a difference as well.
I've just bought one of these batteries, hoping it'll be better than my old one.
It should be. It won't be quite as it was when it was new, as these new batteries don't have the capacity compared to the originals that B&N installed (perhaps a hour or two less runtime compared to the originals). But it will be better than a well used Nook Tablet battery that is fading fast.
I don't know if I need a new battery just yet, but I am experiencing the issue of the power being killed when plugging the Nook into the wall or USB (which means transfers over an SD card, which is a pain). I only spent $5 to get it and I can see why someone might have thought it was broken, since they probably plugged it in to charge it but it wouldn't turn on while plugged in. It does charge while off, however.
What I've noticed in my experience is that if I turn it on, I can plug it in while the Nook is on the N screen, and then it'll go to the Cynoboot screen still plugged in, but the second it goes to boot the OS it turns off.
Anyone have any ideas on why it would allow itself to be on until it tries to boot to the OS?
