Xperia broken? red light under the ON button

Guys, i think my xperia is broken
last night my battery was empty so no big deal i thought.
today i've connected it to the charger to charge and pressed the ON button.
when i pressed it, a red light under the ON button started burning.
i thought? wtf? mayby because it's emty or something.

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

Replacement battery issues

Hi,
Just purchase 2 HTC HD2 replacement batteries from ebay (Non original)
and facing a problem in charging both of them.
When I power up the phone it shows 80%, but when charger is connected,
it does not show the charging icon and the notification LED keeps blinking between amber and green.
Any one got any idea? Both the batteries defective?
I use a meter to measure the batteries, one got 4v the other 4.02v.
Seems ok but just cannot charge inside the phone.
Help and advise needed. Thank you.

Got the same issue here. They will charge up to 68% then stop.
Have to turn off phone and plug in again to charge the final bit - OR - take them out and put in caddy charger.

Battery replacement charging problem
I also have the same problem but this issue happen only if you use the device while charging the battery. If the issue occur try turn off the screen (not power off) and wait around 3-5 mintues then it continue charging the battery without any problem. The problem is occur only if we use the power too much such as Telephone call, Wifi, GPS then it back to blink green and amber again and again. Howerver I found out that sometime after soft reset the battery report it have been charge during green and amber blinking (in my case I upload youtube of 120MB and take quite a long time around 2-3 hours the battery indicate 6% and not increased until I softreset them then become 72%)
Howerver, this is almost not acceptable since it should be charged normally in any condition.

Do you guys think this is due to "low quality" batteries that could not be charge properly in the phone. Can only be charged using cradle....??????

same issue here, except mine will go amber/green regardless of power % left.
I have seen mine doing amber/geen even when it'[email protected] 10% with screen off.

That would all seem to point at the phone drawing more power than can be put in the battery at the same time.
I reported it to the ebay seller in anycase, who says he will contact the factory.

cheap ebay batteries causing problems?

My cheap battery does the same if I use cheap craddle that came with it. However if I use original charger and stock cable it is all fine.
Oh yes and original battery used in cradle does the same orange/green.
However in any case living it for 3-4 minutes starts charging process.

When it's charged up fully it's def a massive improvement on the original though. I can get almost 50 hours out of it now, the original one I had only got 24 at a push

thanks for that, and you definatly think it lasts longer than the original htc ? are you a heavy user?

Yes - BUT - mine came with a 750mA, and I think you guys will have a 1230 right?

Xperia SP wont respond (no flashing problem or root problem)

Hello my Xperia Sp just run out of battery and shut down.I pluged it in saw the sony logo and when i tried to turn it on it would not respond.
The only thing it did was kept the red light on (indicating charging).I tried pressing the off button for over 30 seconds with no results. Not it is stuck and i cant do anything about that.
Help please.

Nevermind the problem got fixed by itself.
The battery (about 2 % run out and the phone kinda reseted itself.It opened just fine.
So if anyone else gets this problem just let your battery drain itself.

Just to confirm you plugged it into a mains supply? USB from your computer to phone charging is not enough to kick start a totally dead battery.
If you have plugged it in to a wall socket and it still doesn't work, give it some time.
I think the battery and the phone's software combine to stop the phone operating at unsafe voltages, the safe operating range for a standard lithium ion batteries is 3.2-4.2 volts (though android may be different). They spend most of their time at 3.7 volts though and this is why they are described as such when you buy them separately.
If, for some reason your phone's software thinks your battery is at 3.1 volts, it won't do anything until it thinks it's at 3.2. Similarly if a protected battery is taken below 3.2 volts it won't provide any power until it hits its minimum voltage. In theory your phone should have cut out before the protection cut in, but bad stuff happens to good people.
Sometimes a protected battery gets drained so much that the tiny flow of electricty required to power the protection circuit stops and as the ultimate failsafe, protected batteries stop working when this circuit is not functioning.
(I'm talking about standard batteries here, not necessarily phone ones)
Sometimes cheap basic chargers won't be able to get such batteries working, but better chargers are able to send tiny trickles to a battery to start the protection circuit and make such batteries charge again. I'd be very surprised if android didn't take this into account and have some way of ensuring over-discharged batteries with a tripped protection circuit can be charged. That said I'm not sure whether the protection is all software on mobile phones?
Like I say give it some time - getting that first .1 of a volt can take a while when the battery is totally flat. If it hasn't changed after at least 2 hours then I'd worry.

The phone was pluged in the wall socket.After this i tried to turn it on (while pluged) nothing happened so i unpluged it to press the off button (i upluged it because i could not reach the button because i had the case on) but the red light ( at the bottom of the device indicating charging) did not turn of.So i tried to reset the device by pressing the off button but i waited for almost 30 seconds (while pressing it) and nothing ... not even a vibration.So i left the phone away with the light stick on till the 1 % left was drained and the phone shut down due to lack of power.
So then i pluged it back in to the wall socket and it started charging again and so i turned the device on.This time it responed and opened up .Now nothing is wrong

It happened again.... i dont know the problem but the solution was the same...

You left the phone in the charger to drain or not? If i put the charger off then red light isn't opened..
Also, how many hours did you wait?

It took about half an hour because of the battery level being low.

Guys im having the same problem.. anyone who can help will be appreciated.

Power off before 0%

I remember have selected an option so the battery wouldn't necessarily shut off at 0%. Now my phone shuts off at approximately 4%. Anyone remember where this option is?
Sent from my Turbo
Click 'Thanks' if this helped

I recently noticed this as well and would be interested if there's a way to fix this.

It has happened to me, too. Yesterday my phone shut down at 25% and 14%, but after turning it on again I could use it normally.
I'm, obviously, also interested if there's a solution for this.

Mine has done the same thing a couple of times. It's only ever happened once the battery is less than 10% but it's still annoying. I also had one random reboot today but that was the only time that this has happened.

I could swear I had selected an option for this...but I can't find it anywhere. Does anyone recall having seen this??

I had some weirdness with this myself yesterday (my 2nd day on the phone).. I was literally laying in bed before going to sleep, marveling at my battery life after a day of heavy use (18 hours and 39% to go, SOT 3 hours) and it just shut off. I tried to turn it back on, but got the boot loader's big fat 0% screen. So I plugged into the turbo charger, and then it said 100% within a minute, I turned it back on, and then it was 85%.. Just decided to go to bed, left it plugged in all night. Took it off the charger this morning at 100%.. then over the next 2 hours it fell down to 55%. Figured the battery just needed to settle in for a couple of days. I've had it on a USB port for about 90 minutes now, and it's back to 100%. I'm going to take it off an constantly keep it between 80-100% all day. Hopefully it just needs to settle in and get some battery stats under it's belt? I've not seen this with many, or any phones before. Would suck to be out somewhere thinking I can make it to the next morning no problem, and then have my phone die 5 minutes later and I don't have a charger.

Has anyone found a solution for this issue?

i am with the same "4%" issue

It probably does that so it can already have a headstart for the turbo charging feature.

Have you guys tried re-calibrating the battery? I've experienced versions of what you describe, and here's how I fixed it on mine;
1 - plug into the turbo charger that came with it
2 - press and hold power button till unit shuts off, continue holding,
3 - continue holding till you see a battery icon on the screen, let go of the power button
4 - phone will vibrate, and a couple seconds later, the battery icon will show a % number, that is the correct level of charge in the battery, it is now re-calibrated!
5 - press and hold power button till phone starts to boot, you should be good..
From what I've read, this "out of sync" battery calibration is caused by using certain chargers other than the stock one. I saw it happen from plugging into a laptop usb3 port and an old blackberry wall wart (don't judge me). Other people have reported it from using wireless charging (I wireless charge every night without issue).
Hope this helps, good luck!

Run a Nook HD+ without a battery.

I bought my Nook HD+ in 2013 and it has been a great companion all along. About two years ago, I noticed that the battery was not what it used to be, requiring charging too often. Last year, I installed LineageOS on the Nook.
About three months ago, something happened to the battery so that the Nook would turn on and be usable only if the main power was connected. If I switched off the charger, the Nook would immediately shut down - and by shut down I mean it would just blink off, not shut down over a few seconds. Also, in the shut off mode, it would lose battery a lot, like 20 to 30 percent in a day, without any usage.
Then, about a month back, I forgot to charge it for three straight days and now it won't turn on at all. When I connect the charger, the charging light turns from green to red, and stays there, indicating the battery is charging, and the back of the Nook also becomes hot, but whatever I do, it doesn't turn on. When I press the power button, the screen comes on and shows the charging icon for a second or two and then goes off. I've left it charging for a couple of hours, maybe six or eight or so, but it still won't turn on.
If I remove the battery and turn on the main power, the charging light keeps blinking green and red over and over. So, is there any way to use the Nook without the battery, running it off the mains power only? And if there isn't, is there any way to turn it back on? I've already gone through the threads here and tried some of the things but nothing has worked. I don't have a higher power wall charger, and it is not possible to go out in the present condition, what with the lockdown and all.
Please help.

Hi
I also have a Nook HD+ that I'm still playing with

I also installed lineage on mine a year or two back, but I've had random issues with mine. I'm going to try to reset and reinstall it in the near future (like, maybe this weekend or next).

I know that, if the tablet runs dead, you _have_ to put it on the original Nook wall charger and let it sit overnight... mine just went dead a couple of days ago and I tried just plugging the cable into a generic USB charger, but it didn't charge. I then remembered this and plugged it into the Nook charger and it charged overnight.
If I remove the battery and turn on the main power, the charging light keeps blinking green and red over and over. So, is there any way to use the Nook without the battery, running it off the mains power only? And if there isn't, is there any way to turn it back on?

I have no idea about this part... I've never taken mine apart (I wanted to buy a replacement battery a few years ago but they ran out and I never found more). Update: I just searched and there are a few battery replacements listed with Google search, I just don't want to pay 40.00 to 50.00 when I can buy a new tablet for a little more than that.
I usually just leave mine plugged into my bedside clock and it keeps charged, or if I unplug it plug it back in within a couple of hours.
Hope you find an answer.

better off buying a new tab
