Battery goes from 90% to 0%

Anyone have the problem that the battery status is incorrect? Sometimes within the hour of fully charing my device the screen starts to flicker and then device turns it self off.
When I restart and charge it the battery bar shows almost emtpy and goes to 100% after ten minutes in only one step.
I am using Sakajati's latest ROM. Only modification I did was replace IE with the previous version.

1. Flash a stock ROM see if still problem.
2. Try a different battery see if still problem.
Both will test hardware or ROM related.

Your battery is most likely dead.

yeah I agree your battery is most likely dead. I had the same problem with my first tilt. It died out cos I accidentally overcharged it a few times.

how did you overcahrge your tilt? i would like to avoid doing that.

You can't, the phone would just stop charging it.

i know the phone is smarter than that, but i figured he used an off brand charger or something like that, just wanted to make sure.

If you use too hot of a charger it can hurt the battery a little bit....
I know that a common cause of this problem beyond the battery is that the phone's calibration to read the battery level gets thrown off. To reset the calibration, turn the phone off, do a battery pull, wait a good 30 seconds, put it back in, then without turning the device back on, put it on the charger and let it chill for a couple hours. When all is said and done, you should have a fully charged battery and a recalibrated Kaiser.

I would not be to quick to blame the battery here but yes it could be that What SPL do you have? If the device acts dodgy whit screen freeze it could be that. I would try some other whit recomended rom and give it a spin before changing battery (ofc. short version is to borrow a fresh one to eliminate).

VERY strange battery issue

I recently received a replacement Nexus One from HTC and within three weeks it has already developed another problem.
Here's what usually happens:
Night to 6AM: Charging the phone
6AM: Pull the phone from the charger
6-8AM: The phone drains battery normally
~8AM+: The phone will automatically shut off for no reason at all, and then I try to turn it back on. After boot up it immediately begins the shut down procedure, with the battery reading ~0% life (sometimes I can't even turn the phone back on after a battery pull, it takes multiple pulls).
I originally thought that the problem was the Nexus was reading an incorrect charge on the battery, so I tried wiping the battery stats. There was no change in behavior, the phone continued to shut off. The only way to fix the problem temporarily is to charge the phone to use it, but the problem persists once the phone is taken off the charger.
I even tried doing a full factory reset, but the device exhibited the same problems after a certain period of time, which leads me to conclude that this is most likely a hardware problem, either with the battery or something with the N1 itself.
Has anyone else experienced similar problems, or does anyone know how to fix the issue? Please offer some insight, as this is getting quite frustrating and I can't use my phone normally until I get another replacement, or I fix the problem.

Can ANYONE help me? I hate only being able to use my phone for like two hours a day if even that.
I will have to start using my RAZR as a back up everywhere I go until I figure this out

CHECK YOUR PM--i had same issue---IT WAS THE BATTERY!!!!! They sent me a new replacement batt and it hasnt cutoff in 2mos!!---KNOCKS ON WOOD DAMMIT!!LMAO!

battery acting weird

hey everyone my sister has a milestone and she is having trouble with the phone battery. she says that she fully changes the phone and then at any point, the phone shows the sign that the battery is discharged and then reboots... then the battery shows the charge again, I tried moving from stock to cyanogen which took the problem away for some days but today it happened again. what can it be help!

hmm. i dunno. anyone?

the weird thing is that she just got it back from warranty... the screen was not working

Sounds like a battery problem. I once had my phone show 1% battery-level for like 7 hours (!) before it shut down. Some other time it would show 100% even though it just had been charged for minutes (starting at 5%). I fixed both issues by recalibrating the battery (search the forum, there's lots of info, most OR even have a script for that). I also leave the phone connected to the charger a couple of hours longer even after it says it's fully charged.
But if the phone actually reboots even though the battery has been fully charged, it really sounds like a hardware problem.

try a new battery

Before buying new batteries, just try calibration.
For me, the mentioned case of shutting down with a so-called empty battery was happening only with a stock 2.1.
Since then this issue never occurred again. So a faulty battery is not necessarily the first answer.

[Q] Battery faulty?

Hi,
My battery life/indicator has been behaving very strangely since yesterday, so I'm wondering if the battery is dying. I know about battery calibration, and attempting it hasn't solved anything. I haven't flashed any firmware recently.
When I plug in the charger while on, it almost immediately tells me it's 100% charged, but the number displayed will still be something low, like 50ish. When I unplug it, the number stays. It drops extremely quickly, to around 1-2%, then 0% and turns itself off. After turning it on again, it may rise to 10%, but drop again to 0% shortly thereafter. After a couple of times of turning it back on, it will refuse to turn on. Charging only seems to work when phone is off, but even then the charge won't last much more than a couple of hours of idling - no calls, no web, nothing.
I've tried charging to full while phone is off (drained), and removing battery stats via cwm before booting up. Doesn't help.
Is my battery faulty? It's a very sudden problem, and my battery has been lasting me for days before this happened

So, I got a new battery. The problem persists. I've tried a factory reset/wiping battery stats, but it's still that way. Could this be a hardware problem somehow?
Any advice is greatly appreciated!!

Which fimware are you on? In your case I'd go back to a stock firmware from samfirmware.com and test once again. If the problem persits, you likely have a hardware issue and I'd have it swapped for a new phone whilst within warranty.

I'm using tweaky rom, JVS. I'm not too sure what the local firmware is (Singapore), the one I had before I switched to custom was 2.1, and I don't feel too safe flashing bootloaders when the phone is prone to turning off...

yeah, you are absolutely right. Have you tried betterbatterystats? ( http://forum.xda-developers.com/showthread.php?t=1179809 ) It will show you wakelocks when your phone should be idling.

Did it help ?
Mate, out of curiosity I was wondering if your issue got resolved.
Also, you should check what is draining off your battery.
I tried reading elsewhere and found "Battery Monitor Widget" could be useful for you to identify this.

Nope, still same problem. It's not a wakelock issue, because the battery dies /so/ fast. I can literally charge it to 100%, unplug the charger, and in 30 seconds it says 0% and turns itself off. The phone itself isn't running hot or anything, and seems to be just idling. [Edit: To clarify, it also charges to 100% in about 10 minutes or so. I'm guessing that for some reason the phone thinks the battery is 'full' and stops charging, leading to the quick drop. I've no idea what could cause this though]
I'm hoping that maybe it's a software issue now since the new battery isn't working either (the battery is probably a fake since i got it for cheap, but even then it should last at least a few hours before draining), and that the phone is confused with battery voltage levels or something when I put the new one in.
Anyway, I flashed JVU stock, didn't even root, and will be charging the new battery overnight while phone is off. It says 100%, but gonna leave it on charger anyway. Hopefully if I wake up tomorrow it'll be working :/
If that doesn't work, will be flashing DXJV9 (My original firmware was dxj4), and hope that it's the official one here. Then bring it to a service center and act dumb and hope they can fix it i guess...

Service center replaced motherboard. There goes a hundred bucks :/

[Q] Note Died, What the heck? *Detailed*

Hello, I first wish to say that I did a basic search and didnt find any info. maybe I searched wrong since this is first time this has happend to a phone I know of.
second I don't have time to do a full extensive search, sorry if it looks like I didnt search but I did.
Anyways here to the problem:
What happend? Well the Note just died. from simple usage. the screen is all black, won't boot at all, can't even see any lights. (Got Desire HD, Tho I don't remember this phone had a charging/signal light, but I believe it has)
The Note is my mothers so she wanted me to look at it.
There were no problems during flash or, rather it wasnt me who flashed it. but got it pre-flashed of tradera (part of ebay) and nothing was wrong besides old rom, was waiting for full drivers ICS since I havn't seen one for the N7000 so I havn't flashed a ICS rom since my mother needs the most support but anyway
I tried taking the battery of and putting it back again (Fixes 90% of my problems!), I tried fail-safe booting it. I am kinda stumped on what to do, so if know whats the problem and if its a cheap one I will be happy to do it. hopefully its not a motherboard replacement... :-( then I will cry...
Edit:
It turns out it started working with 25% battery after being having battery taken out for 1 hour, and was in the wall socketed charger for 7 hours. YAY!

So it just died in middle of using it normally?
You didn't do any wipes or such in recovery and then it didn't start after that?

I am not sure there is enough detail here to be able to help. But if it does not go to download mode with the usual ways or with a USB jig, then it will need to go to samsung repair centre, or you could try to JTAG first.
But if it is a result of a bad bootloader flash, then JTAG might work. If its due to a bad ICS kernel flash, then motherboard replacement is most likely.
Hope it works out.

First of All, it doesn't have ICS yet. (since i havnt found a good kies ICS yet that everything works on yet, havnt checked the past few weeks)
Second, it died in standby mode, during work when she was gonna take a picture for her work (she has card that allows usage of camera during work place in volvo)
Third, it wasnt during flash or anything. I will have to check the phone with shidapu when he wakes up... ARGH HIM! for not having normal mornings where you wake up around 6 or 7am...
I believe it didn't die during middle of usage but when the phone was in power save or whatever its called when the screen is black and not phone in use but in operations
I guess JTAG is the only option, but how does that work exactly, if possible please do link
because my computer can't even see the note when I am connected to it with USB. can the battery died? since I don't know if the note can be powered up without battery. *tried connecting without battery but no luck :/

Try to remove the battery for a couple of minutes and then insert it again and connect the wall socket charger and wait up to one hour. The Note has a charging animation but if the battery is totally drained i think it won't show directly.
If you having troubles finding another battery to test with you can always come by Astra in Mölndal and try mine as i see that you are living in Gothenburg.
Jtag is a service in that someone solders small cables to the mainboard and reflashes the bootloader on a low level. But this is only if you know that you have failed a flash or such, don't think this is the case here.
I did send a SGS2 to mobiletechvideos in Texas for that service, and i really do recommend them and thier great service.
Good luck.

if shidapu can't fix it that is (irl mate of Shidapu) he know a bit more than me about Droids
sadly don't have have a extra battery I believe, but I do what you said, I will pull the battery off for now, and when I see the phone next time I will put it in and wait a hour. if all above fail, I might P.M. you that i might be visiting you =)
edit, connected to a wall socket, does it make any differs if I use my HTC wall socket charger?

umm..mind if i say something....?
well u can use any charger since u need to give charge to the battery.. but recommended is charger for note.
Next i had a problem with my battery as well. try to put the phone on charging (there ain't any charging light on this phone ) but you'll see an animation of battery. if it shows up don't worry your phones safe but not the battery but if it doesn't then i think there's some problem with the bootloader or the kernal ...

Hiya guys, after having the Note on charger for like who knows 7 hours or so...
I actually could boot it! YAY! got into the droid as usual.
But there is one wrong thing... it says 25% battery left. orange...
now it says 26% =)
Well I guess I have to reset the state of the battery? (battery-memory wipe or whatever its called?) if thats possible, if so is just simple CWM? (does Note even use CWM?, I am a HTC user and it wasnt me who rooted that device as I mentioned earlier so I dunno what recovery software there is for samsung)
Well Anyways, might be just some faulty battery. guess I have to order a new one if it does it again.

maybe u should take the battery off the phone for a while and try to charge it without booting the device . maybe then it will work fine. just do it three or four times whenever you charge your battery. this way the battery will charge efficiently without it's use on the phone... i hope you got it since i am not able to type well today as i am right now a lil bit anxious about my notes problem

I believe i mentioned it started working. Charging it after removed battery for a hour or so fixed it. took a long time tho, 7 hours for 25% full battery. (26% short after, well samsung are known for their extreme long battery load times... galaxy tab 10.1... that was a device that took over 2 hours to charge...)

It might need a new battery.

The same thing happened to my Note yesterday. It was last charged on Saturday and, with light use, after three days it still had around 50% battery charge remaining when I went to bed on Tuesday night. Yesterday (Wednesday) morning I tried to wake the Note and it was completely dead. Of course I did not expect a flat battery, given the usual discharge performance of my Note. I removed and replaced the battery and hit various buttons and absolutely zip. I connected the charger and again no response. Nothing lit, no beep, nothing.
It's probably worth mentioning that I'm on the latest stock Samsung ROM and unrooted. I really thought it was FUBAR and would need to be sent off for repair. Anyway, I do have a jig so I plugged that in and the screen woke up, so I knew there was some sign of life. But still it would not boot.
Anyway, to cut the story short the battery was as dead as a dodo. I don't know why. It should not have been. I left it on charge from the AC charger and after a short while (a minute or two maybe) the charging symbol appeared with a hazard triangle upon it. It took over 4 hours to finally make it to a fully swollen 100%. The phone is almost exactly six months old and this is the first real scare I've had with it.
I only bore you with the tale because it might give hope to people who think their phone is bricked when the fact is that nothing worse has happened than the battery has gone (unexpectedly) very flat. Right now, 27 hours after I finished fully charging it the battery is down to 92%. That's the sort of performance I am used to. I will leave it without further charge for another few days to see if a similar thing happens again. Hopefully not.

yes i know u said that it started working. What i am saying is that whenever u want ur phone to charge switch it off and then charge(this way it will charge efficiently) . just follow it 3-4 time when u charge it and your battery will be on the right track(i hope that works). my note takes upto 1.3 hour (nearly) to charge completely from 10%. and when it's switched off it does the same in 45 minutes... what a difference!!!
try it and if it works for u then this way would be a best alternative to replace battery for charging issue (of course if ur device is still under warranty you should opt for a replacement).
