Red LED when plugged in, NO LED unplugged. Will not turn on

Does this mean my battery is dead? I pulled it out of my briefcase this morning, and it wouldn't turn on. I plugged it in to the wall and it powered up and sync'ed up (at least my data is backed-up), I left it plugged in so it could charge and when I came back to it, it was dead, just a red LED on the right side, and thats it. I've removed the battery and reinserted, which didn't do anything. Do I need a new battery?
Thanks for any info,
Brock

HELP TOO
I am getting a similar thing and I bought it used about two nights ago. Mine occasionally turns on, but 'bombs' out again if used too long

your pocket pc out of battery, charge it again till full......

I too have started having this problem since the weekend! My phone constantly shows the red light whenever on charge with cradle or direct from wall!!!!
Help please!

the red light used to show that the battery are low, you got message or got miss call.... try to check all that first or try to soft reset once....

Thats the problem though, the battery has run flat and whenever I put it onto the cradle to recharge the red light just comes on. If I put the battery directly into the cradle the red light comes on the front of the cradle. This is happening with both of batteries.

Last time the battery on my phone went flat enough for the red light to come on it took 48 hours constant charging before it started to work again...

Maybe your phone has a short in the charging circuit, the battery or the part of the PCB where the battery connections meet the main circuit?

I had this problem with mine.
i left the battery out for about 24hrs..
then put battery back in and left phone to charge for 24hrs..
it then turned on and has been fine since

this things happened when the backup battery is completly dead or dischargd i used to have this problem but i opened the xda2i and recharge the backup battery "ofcourse i took it out "and it has no problem since only that the battery metter is working weird so the problem is that ur backup battery is completly discharge
how to fix this easier just let the xda in the craddle 24 hours with the main battery on it should work unless is blocked the u need to take the + from the backup battery out and put it back on after a few mins and that's it u got ur xda2i working again!!

Hello dear friend, I sympathise with you I had this exact same problem and was worried sick for a day and a half that it was dead! the red light under the power button is the battery fail light (as far as i can tell) it goes on for example when you plug the charger in and remove the battery. I've found if you run the battery down to absolute minimum it almost seems like the X1 cant detect the battery any more and displays the red light. I fixed mine by removing and replacing the battery a few times and plugging it into the wall charger for a few hours. keep trying and dont lose heart, like I say it took me a day and a half (with a sleepless night inbetween

Also mine, but after five minutes it's wake up.
Try simply to remove battery, or performe a soft reset via hardware button with the stylus.

Let you X1 charge for an hour or 2 and it will start up again, guess this is when the phone don't get a enough power to start up.
(Guess it can indicate some other error as well but probably just lack of juice in the battery .. )

thanks guys..
it is still not working but i know that the phone it self is OK.
i wend back to the store and they switched the battery from another xperia.
it worked fine
i'm so happy right now. it's charging at the moment, but still not going on, well, i have to wait and see then.
again: thanks for the posts guys

Mind you... it might take a while! I had it connected to a cheap usb charger for a night (which wasn't good enough obviously) and it took me the better part of a morning to get it to life again with the SE charger. I find it most irritating that this sort of thing isn' t mentioned in the manual. At least not where I could find it. Things like a phone that doesn't want to start make you sweat horribly.

I have this problem with mine but still no luck
Been dead for weeks now.... Finding it hard to get a copy of the receipt too bah
Only had it a month too..

It's prolly one cell in the battery that are "broken".
Had that on my X1. There are 3 cells in the battery and if one of them doesn't work as it should, the battery only delivers 3-3.1 volt.
Your phone "wakes up" at 3.335 volt but dies at 3.1. I've been measure it myself.
My phone are now back in business with a new battery, a new batterycover and latest software. No problem if you have guarantee...
PS... Try to avoid one thing. Avoid heat in battery. Lithium hates heat.

You are right, man.
Usually, if you discharge a battery till the very last drop, it can happen that:
A) one of the cell goes beyond its safety level, and it "breaks". That's unrecoverable, AFAIK.
B) the cells gets unbalanced, and you nedd several charge/discharge cycles to get them balanced and fully recovered.
Add to this that Usb charging is usually unable to wake up an almost totally drained battery. This won't happen with a normal charger, but Usb charging voltage is lower than normal (of course, it's usb not home plug!) so it has not enough power to wake up the dead battery. If you leave your device in charge for some minutes, it will eventually manage to wake the battery.
However, I noticed that the X1 has a bad power management. Usually my X1 low level battery threshold varies between 10% and 5%. One week ago, at 10% it just shut down and won't recharge, showing me the red light over power button. Removed battery 3/4 times and charged with home charger, it gets recovered. Try to plug the charger, remove the battery and insert it again, doing all this with the charger always plugged.
In my opinion, that's really annoying, I never know when it *really* has a low battery!

yeah.. i had that with my P990i (symbian uiq3) phone the batter went in 1 day to 50% now it still has 80%

this same thing happend to me last night, i just pluged it to a wall charger & waited for an hour good thing when i pressed the power button it came back to life. was worried then and now its all good.

i had this on my xperia a while ago i think its just the battery is extremely dead.
after an hour of being plugged it in it turned on again

Red Power button Led
Glad to find this info, the red light gave me the chills at first too. My phone blacked out while using TomTom 7.4 on a stock unbranded NL Rom, after it had given me low batt. warnings. Now it's in the 'home plug' charger, sipping juice on the red light... I hope it comes out of it soon. Anyway, I was wondering if anybody has ideas on checking battery cell failure? Or battery diagnostics of some sort? It would be a shame to use a crippled battery just because you don't know it's operating below its max capacity. By the way, I'm not part of the lucky bunch in possession of a multi meter...
EDIT:
As soon as I hit 'post' the notification Led's display charging! And the red light's off of course. Guess the first post brings some beginners luck, hehe. Anyway, thoughts regarding battery diagnostics etc are still welcome!

Encountered this and according to the helpdesk, it's cos the backup battery is empty so he advised me to charge the phone for half an hour without the battery, and then charge it with the battery after that. Didn't work. Called up the helpdesk again and he said for some, they've to charge (without the battery) for an hour. Ok, tried that. But still doesn't seem to be working. Gonna just leave it charging (with the battery) for a few more hours. If still can't guess I gotta bring it down to the service centre.

there is a backup battery in xperia???

Remove your battery, wait 3 minutes, insert again the battery. If you have lost date & time info, no, there is no backup battery, otherwise yes, there is.

Well, anyway, sent my X1 for servicing. Over at the service centre, they tried to 'boost my battery' but couldn't get it working. So had to leave it there for them to work on it.

Just had this same problem, cleaned the battery terminals and hey presto...it's all good again..
Regards,
Astoroth

Sent my X1 to the service centre with regards to this issue and they replaced the motherboard. They'd tried boosting the battery but no use.

Same problem.. this is what happened
ok, I came back from work an as usually i plug the charger in my xperia, the baterry left was like 30%, ok, then, I connect in the 3.5mm an autput for a big Radio so i can listen full music... so.. in a while, in my house there was a power down.. really fast one... like... 0.01secs... (like down and up really fast).. in that change my cellphone went down =S.. and sice today never get up ='(... there's just that red light in the power button each time I plug the charger on... any help?.. is the same problem of the topic? :S.. plzzz.. i dont have even a month with this pretty cellphone =( poor baby

[Solved] Upgraded to CM7 RC14 (doshaska), now battery will not charge on my Milestone

Edit: thanks to this post, my problem has been solved. Thanks!
So last night I went from stock motorola 2.2 to this wonderful-seeming version of CyanogenMod on my UK milestone - the install went flawlessly, but now I have a problem - my battery is not charging at ALL.
While the phone was on last night after I charged it, it was plugged in, first to my PC and then to the wall socket. In both cases, the battery indicator had a ? (question mark) on it.
I thought it might have been some weirdness with battery calibration so I left it and plugged the phone in from the wall to charge overnight. This morning, my phone was telling me to connect my charger (despite it being plugged in) and on removing the power cable, it died due to no battery power left within 10 minutes.
While plugged in from the wall, the battery indicator comes up but again just contains a ? on it. The little white light next to the power socket never lights up.
If I plug the phone in to my PC via USB then if the handset is OFF, the white light comes on and around 10 mins later it gets enough juice to boot up. The problem is that when the CM7 software starts, the little white light disappears, the phone stops charging despite the cable being present, and it then dies 2 minutes later.
I know the battery is fine because it was perfectly fine before I installed CM7.
Anyone else experienced this problem and/or know how to fix it?
One thing I did manage to do before it died was install a battery calibration app that I found on xda-developers - this told me that the battery was running at 3267 mV - any idea if that's good or bad?
(and yes, I'm using precisely the same cable/charger I was using before I put this version of CM7 on, so I know they are fine - they charge a friend's SGS with no problems)

Try plugging the phone into the wall charger, without the battery. Try and boot it up and let it boot. Once it's booted up, give it a bit and try and put the battery in and leave it to charge.

What happens if you turn off you phone and plug it in a wall charger? If the problem isn't in your battery it will charge fully.
When you phone comes up, try to disable the 1% battery steps in settings. I got a problem with it, and after disabled/enabled it worked fine for me.
Hope this helps.

On plugging it into a wall charger, the phone comes up with its special battery charging screen (i.e. a fullscreen battery level indicator) - no amount of pressing the power button seems to get it to boot properly (with or without the battery).
I'll see if I can get in and get rid of the 1% steps thing later, thanks for the suggestion

Dude, that was PERFECT.
Managed to get enough juice into the thing to get into the menu for a moment and was able to disable the 1% battery steps option - soon as I touch that tickbox, the battery indicator switches from a ? to the charging symbol and the phone starts charging. Thanks a million!

Nop dude, you are welcome

will atrix hd run plugged in but without battery?

I'm asking this because my phone spent whole night in some strange looking juice. In the morning when I switched ii on there was a msg about cooling down and since then it never started again.
So after one week I opened it and cleaned each possible part (there was a lot of dry greenish liquid everywhere).
When I put back all together again nothing worked - the green led was off - power button did nothing (only battery inside, no charger)
When I plugged the charger the green light was on but again nothing worked. Power and volume down buttons ddid nothing - only the led blinked once and than stayed continously lit.
I'm 90% sure that battery is dead because when I check voltage on that sticking ribbon one of 4 connection points shows nothing.
So I removed the battery and plugged the charger - and again nothing worked - only the green light was on.
so please somebody tell me that it should be that way I mean atrix hd will not run when plugged in but without battery - so I will still have some hope that only battery is kaput)
thank you in advance.

Why do you switch it on after its been in juice?

well that's a good question
didn't I mention there was a party that night? - well I just did swich it (without too much thinking)

i took my atrix hd apart and removed the battery. my green ligh comes on when the battery is out as well. however, it will not power up. so my question is the same as the op is there any way to test the phone to be sure it is the battery and not the phone? im willing to buy another battery if i know for sure.
thanks!

[Q] Battery will not charge beyond 10%

So I seem to have a strange problem; my phone seems to be unable to charge my battery beyond let's say 10%. For the first couple of minute when I charge the phone via a usb connection with my pc; it displays a battery filled about 5% accoumpanied by a yellow triangle and a black exclamation mark in the triangle. Then after some times of leaving it in the pc; it does show the original battery screen, a battery filled up to about 10% with five black/grey dots underneath it, and one-by-one these dots light up.
I am on a rooted xxla4 rom with the accompanying kernel..... (I can't perform a "wipe battery stats from this CWM version" and I would like to stay on this rom, because it at least a bit like the stock rom, since I don't know whether with this battery situation I will ever get enough battery to install the stock rom again with odin 3.04 )
**Originally I was a while on Asylum 10.1, but then I tried out Parandroid 2.99 beta and to improve the performance I installed Rhythum kernel, when I was a Asylum about two days ago and everthing still worked properly I had about 7 hours of battery life and my phone charged (with the wall charger) to about 100% in three hours. I can't imagine a battery to break within 72 hours and I also can't imagine Rhythum kernel or Parandroid to have caused this, but if I am wrong PLEASE CORRECT ME.

Hi,
If i were you, i'd flash a kernel that supports remove battery stats and remove them.
If that doesn't work, you could try to flash your rom again, but this one is tricky...
because your phone doesn't charge further then 10%.
I don't know about the rom you said, but use a rom without aroma to be sure the least battery is drained...
I hope this will help you.
Good luck.
Cheers,
Kreekhoorn
**Not to forget to keep your phone into the charger (wallcharger) while flashing, just to save battery.

Do a battery calibration using apps in the store, may be the 10% is 100%
Sent from my GT-N7000 using xda app-developers app

Well, the 10%, regretfully isn't a 100%, because the phone kicks me out after about 5 minutes, because it says the battery is empty. I also can't use the battery calibration, because these apps say the phone isn't fully charged so they close.....
(flashing a kernel is possible, but because I can't get into the phone anymore; the battery now remains dead. It seems I am quite cornered now)
**But do you guys think this problem is purely battery related or do you think the phone itself is broken, I mean if just the battery is broken, I might just get a new one, but I don't want to buy a battery to find out the phone itself is actually broken....:crying:

I would first try a different battery

I will need to buy one either way, since I don't own a spare battery and don't know anyone with a spare battery...
**Recently I tried to flash Asylum back on my Note, because it had a kernel which is able to remove the battery stats, but Mobile ODIN got stuck at about 12% of flashing the rom-> so now when I put the phone into the charger, it does not get beyond the picture of the battery with the loading sign within; does this mean the phone is broken? And are you still able to charge although the phone's UI does not show the battery is charging....(So does the battery still charge without the loading interface on the phone?)
->Also when buying a new battery do they at least come a bit pre-charged or are they sold completely empty? Does anyone know anything about this?

Keep the charger plugged in with the phone off for a couple of hours. Download a good custom rom. Boot into recovery and most uab storage. Copy the rom on to your phone. Perform all wipes and installation the new rom.
The new battery comes with a little charge in it.

Thanks for the advice, I have bought a new battery. It is shipping to me; I hope this will resolve my problems (key will be whether the battery is already charged a bit, because I don't know if it will charge in my phone. Since I don't have a rom installed (mobile odin seems to have deleted my rom, but did not continue to install the new rom.....)) Fingers crossed!
(I also kept the charger in the phone some time, but it just does not want to charge; in the very few times I can enter download mode, I get the "can't download battery is too low" message)
->I will let let you guys know if something changes!

There are external chargers which are pretty cheap. This will help in worst case scenario. Anyways good luck mate

New Battery just charges 3% in one hour
So I recieved my new battery, and flashed a new rom, but I seem to have an other strange problem; I let the phone charge for about an hour now, and the battery just went up by 3 percent. Has anyone else seen this kind of behaviour with a new battery (the store from which I bought the battery said it was an original battery -> http://www.mobilesupplies.nl/battery-samsung-galaxy-note-n7000-eb615268vu-p-13527.html (link to the battery I bought))
->To put this in perspective the battery I previously had (which is apparantly broke now) charged to 100% from 0% in just 3 hours.....

try a few charging cycles and then check the charging time

This probably is a bad question, but I suppose it is better to ask than just to assume; does anyone know whether clearing my battery stats will improve the rate my phone charges my battery? I assume the phone remembers the battery stats taken from my previous battery, which might influence its usage of the new battery?

I don't think so as it's regarded useless clearing battery stats in recovery.. That's why it has been removed from the newer version of Cwm recoveries.
Any how charging the battery to 100% resets that file

The same problems seems to also pop-up with this new battery, I suppose there is nothing else left to do except for sending the phone to the repair center.
->The phone does show something is plugged in, it does detect the usb cable connected to the wall charger which is consequently connected to the power output in the wall. The image it shows (BASED ON THE CHARGE LEFT IN THE BATTERY, so it does not show anything when the battery is empty) is a battery with a yellow triangle and a black exclamation mark inside the yellow triangle (the same icon I got with my old battery)
The battery also does not get hot neither does the phone in the slightest bit; and in my memory, before this problem occured, I remembered the phone getting at least a little bit more warm.
I suppose now all that probably remains is for the Samsung service center to either check the charging circuits and try to fix those OR replace the entire motherboard (which what I assume they will do). I just hope they are not going to make up some excuse about the garanty, because I have always treated my phone with the utmost care....

may be its just the USB module that needs changing.. Samsung should do it.

Well i also juat got a new battery this week. I went for the samsungs spare rather than the mugen extended or the gold battery.
My old battery got swollen and its because of my fault, i used to keep it on charge throuhout night to get 100% in the morning but i was surprised coz despite being in bad shape it was giving me a goos battery time. But after a discussion here on xda i got a new battery and i am happy now coz its giving me 30% more time plus i got extra power now
Sent from my GT-N7000 using xda app-developers app

I have the same problem. Does any one have a fix?

When you put your micro usb cable inside your note's usb port, does it wiggle? If so there is nothing else you can do, but to sent your phone to Samsung for warranty. They will fix the usb port and maybe even replace the motherboard. And remember don't wiggle aroubd your phone when it is on the charger or usb plug next time....
