Battery icon has yellow triangle and thermostat icon

Hello all,
I left my phone charging over night as usual. When i woke up i was surprised it had only 32%. I plugged the charger back in, but the phone wouldn't charge. I restarted the phone and when it booted up it had 60%
After some standby time it showed 50% .. really confusing. I pulled the battery out and when i plugged it back in and "before" turning it on. The green battery icon came on flashing with yellow triangle and red thermostat (see pic).
It won't boot up until i plugged in the charger. I left charge until 100% and tried to restart. I got the same icon again and had to plug the charger in.
Anyone know the meaning of this? Battery app showing temp as 36C after boot up. Now it shows 34C. I did attempt battery stat wipe too.
Please share with me your thoughts.
EDIT: I returned mine for a replacement. After that, my nephew admitted that he spilled something right over the usb.

I had a similar problem. When the icon comes up plugged in, yank the battery out and shove it back in.
If that doesn't work, when plugged in take the battery out, unplug the phone, put the battery back in, and then plug it in.
It worked for me!

HEY!! that worked for me. Thank you sooooo much

OK guys, it came back again. The issue is not resolved. Perhaps a battery failure?
I waited for my battery to completely run out. Then charged it all the way up. Then a simple battery pull out and in takes it down to around 80% ?!
Strange stuff here.

Sounds like a very delicate procedure xD

it seems i am the only one with this issue :/

Sounds like the battery just isn't being calibrated correctly.
Let it drain fully and then take it out and put it back in. Chances are it'll turn back on. Let it drain again until it shuts off and then charge fully while the phone is off.

Probably your USB got polluted or bended.

i also think it is a usb issue. i updated the original post. By the way before i returned it for a replacement i tried using a qtip and "contact cleaner" and sprayed some on the usb. After 30 mins i was able to charge normally before it was acting up again.
Bottom line: clean your usb.

Cheers a bunch for your replies! Gonna clean my usb again & carefully "bend" it down a bit. I'll post the results later

Hahaha I laughed so hard in a bus after reading your edit. What a cute nephew
I feel sorry for you though

Tried everything, including a couple of factory resets/wipes. Sent it to the service center yesterday

For me the main idea from using SGS2 for cpl of weeks before selling this crap:
'Do NOT buy korean smartphones !!!'

I cannot disagree more. This is the most fantastic phone I've ever had. Feel free to check my signature. I've had worse. Haha. Much worse. This phone has only lagged twice in the months I've had it and I had to do a battery pull once. I've had my iPhone 4 crash more times than this phone.

I've had charging problems with my SGS2 as well. All of a sudden it started switching tap&talk on and off. Turned very warm and drained the battery juice.
When I attached the charger, it didn't show signs of recognizing that it was attached. I tried to switch it off, and on again with cable connected. Then it started charging, but if I unplugged and tried again it failed again.
So I had to send my beloved SGS2 for service. Now heading on to two weeks without it, i'm growing desperate from having to spend the time with my old Samsung Spica.

Have a look at the charge port problem thread in general. Few of us have had this problem for various reasons.

i also have a kind of similar problem on my S2, suddenly it stopped charging, when i plug it in i tries to start up but isn't able to & then restarts.
i get the normal battery sign when you plug it in after the battery completely dies (no thermometer), nor does the phone or battery gets hot. is there any solution or should i just take it to a service centre? BTW my phone is rooted & loaded with a custom ROM.

Note 3 died while charging

Hi all, my note 3 just died in a strange way.
2 hours ago i it was working in the train. When i got home it was about 10%. Took it out once while smoking and put it back charging again. Half an hour ago i turned on the screen to see if i got any messages. Turned of the screen again. Half an hour later i wanted to check again, but the phone was off.
It wont turn on anymore. Tried my second battery, not working. Checked my usb cable, it was charging my external battery.
After this i plugged the phone in to charge again to see what would happen. I dont see any battery icon in the screen, the led is also not working. The battery feels cold. But the area around the camera is pretty hot. Still won't do nothing.
Has anyone any idea what this unexpected dead is about? Not rooted, not wet, not dropped, like i said, i was checking my messages half an hour ago while it was charging.

have you tried taking your phone into recovery mode (volume up+home+power)?

Yes, it is not reacting to anything. I thought maybe the power button is bricked, but that would not explain why it is not showing the battery logo and led light while charging.

you might consider claiming your warranty

I will, just checking if this situation is familiar to anyone.

Plugged usb cable into my laptop, took out battery, connected phone to cable, tried recovery and power, both not working. The upper area of the phone gets hot though. So the laptop is giving power to it i guess.

Think warranty mate sorry shouldn't be get hot

Ok thanks, what a shame.
Any technical people who might have know what caused it? Could it be a power shortcut or some kind of malware in the background? It's a really stupid death.

Mine did this
Was only 2 weeks old.
Took it back to the shop, and got it replaced.
It wouldnt charge even with the phone off
Common fault with them

similar thing happened to my wifes s2 turned out to be the motherboard

I have visited a support center. They told me the battery was giving 4.2 Volt to the phone instead of 3.8 Volt. So the phone and the battery are both broke. He told me this doesn't happen often.

Sounds like a hardware issue almost.
I would maybe try connecting the phone via USB to pc. Pull battery and and replace. Then try booting into download mode. Open Odin and check if the device is recognized.

doesnt sound like a brick... truth being, its almost rare " hard bricking " samsung galaxys.. soft bricking is very common.. i bricked a HTC EVO a few years ago... symptoms: press power.. blue light blinks and the shuts off.... pop out batt, plug in, usb to pc....all do nothing....
sounds like somehow there is a batt problem.... TAKE OUT BATT... LAY it on a super flat serface.. now try and spin it!!! or does it rock around like its uneven?... means the batt is swollen in the middle and is no good... that maybe ur prob.

thanks.
battery spins like a turntable.
both my batteries spin like a stripper actually.....
i have used 3 different computers, countless usb cables and ports.
i used my friends battery to make sure it wasnt my batteries, phone still doing the same thing.
its so odd.
it was working perfectly fine.
now when i put the battery in, it automatically turns on, but only for a split second.
then it turns off.
i know its not suppose to turn on automatically, but i cant even get it into download mode because it shuts off within seconds.
im at a loss

Well.. if you have insurance, call them and tell them the device just stopped working... they will fedex you another overnight.. all for a 100.00 deductable....thats a way out.

I have seen similar stories from people that had defective power buttons. what if you hold the vol down button when you insert the battery, does it behave differently?

[Q] LG G2 Red Light No Power

Hi All
My friend recently gave me his LG G2 as it had a problem.
What happens is currently if you try and turn on the phone nothing happens. When you plug the phone into the charger the red led blinks and nothing else happens. He told me that he got the phone brand new off eBay and that the problem started after he left the phone plugged in overnight. No software modifications have been done to the phone prior to the red light issue.
After some investigation into the issue i found nothing except another eBay listing with a LG G2 D802 where the guy got water into his phone and it has the exact problem where the phone does not turn on and a red light comes on when attempting to charge the phone. The eBay listing also says that the phone was seen by a service technician who said the circuit board was damaged but is repairable
Before i spend any money buying spare parts does anyone have any idea on what the problem is and whether its worth fixing?
Thanks

Could it be that the motherboard got damaged?

I don't think the mother board got damaged. I had the same problem with both my G2's. (D800 and LS980)
I had changed the motherboard from ls980 to the d800, I connect everything, LCD, digitizer, battery,front and back camera ..etc..
I go to try and power the phone up but nothing happens..
I go to plug in the phone.(Nothing happens)
I use another charger(nothing happens.)
My phone wasn't water damaged though. In your case you could open up your phone and disconnect the battery connector, After about 1-3 minutes connect it back & leave phone alone.(don't try to power up)
I had a problem with one of the phones not having the red LED light coming up to tell nevit was charging. I switch the battery to another bezel & motherboard & it shows 40% battery level.
It definitely worth a try to open your phone & disconnect and connect the battery if the phone was charging one night.. I remember seeing a forum on here that the phone might be still on charging mode or something.

Hi,
I have the same problem, the only sign of life is a red flashing led when I try to charge it up.
My lg g2 (D802) did get water damaged tho, however I don't think it has been damaged that bad. When I found it in the watery environment it still worked, but it was quite warm. First hour or so I put in in a towel, because I wasnt home. When I got home I discovered it was dead. Then I put it in rice for two days, but now this problem occurred.
I reconnected the battery (twice) but it didnt change a thing, and now it still won't boot up...
Hopefully someone can help me (or sees this at all),
Thanks in advance

I have the same problem with my G2. I changed the motherboard after it got water damage but nothing else changed. what should i do?

Solution for blinking red error
Hello Guys,
I have the same problem like you others. 8 times red blinks, phone won't charge, PC won't recognize it, dead at all. But I found the solution. There is a short circuit on the moterboard. That can be LCD, digitizer, buttons or anything other. I have unpluged digitizer connector and BOoM!, connected it to charger and turn on with power button. So you guys can test what's making problem on your MB, it can be anythinhg. I hope that will help to someone.
Sorry for bad English.

same thing here
I have an LG G2 that I recently replaced the batter (ordered from ebay). After the install, the phone just blinks the red indicator light. When I hold the power button, it blinks 8 times, pauses then starts over again blinking 8 times and pausing. Please help.

I have the exact same problem. recently bought a new battery, because my original one is increasing in size (very strange) and decreasing in power.
When i put in the new battery the phone doesnt work if i try to turn it on. When i connect the battery to the charger its just the blinking red light...

I'm having the exact same problem...working ls980 phone using to restore my D801 motherboard....but have no power.
When I plug the ls980 board back in it works again. Last time my D801 board red led blinked 2x but wouldn't startup with its own battery. How did you fix it?

It is the battery. either the cable is ripped or the battery is at 0 volts I've just tested this on my LS980 using my analyzer to fully charge a battery externally to 100% made it work fine, please check the battery cable its very thin and very easy to rip without knowing it. (I work at a battery store) Hope this helps some of you!

A solution for 8 Red blinks:
If you have 8 Red blinks when you change the screen the Solution is:
The two metal joints from two small boards (besides volume and power button) that connect to the motherboard they should be completely attached to the connector.

Help! Battery drained, phone won't turn on, battery charging icon flashes on and off?

My phone had been working perfectly fine, as well as charging perfectly fine. Recently, I accidentally let it drop to 0%, which I don't usually do. I went to plug it into the same wall outlet as always, but instead of the usual charge process, the battery icon with the lightning bolt in the middle simply flashes on the screen and then turns off, which happens over and over again.
It should be noted as well that about 3 weeks ago my phone get fairly wet. After that incident, I turned it off till it dried, powered it up, and everything appeared to be totally ok. No problems since then until this.
Other facts:
-I can safely get into the recovery menu (power + vol down), which is stable, but any menu selections result in the Motorola splash screen for a quick second and then the phone powering down.
-The computer will recognize the connection to the phone.
Attempts to resolve:
-New cable, new usb hub, new wall outlet
-Trickle charge from the computer (same flashing)
-Phone in rice to remove moisture
-Toothbrush cleaning of Micro-usb port (suggestion from another thread)
I'm pulling my hair out, and I am considering prying off the back and replacing the battery. I have searched other threads, but have seen various solutions none of which worked for me. If anybody has any idea how I can fix this please help!!!
Thanks in advance.

Unfortunately most probably is the hardware problem. I had similar issue with razr. Splashed it on the beach, quickly washed with tap water, dryed it and for couple of days like nothing happened. Then suddenly digizer stopped working. It was motherboard. Luckily one xda member donated me the same phone with broken screen so I replaced motherboard by myself.

Thanks for the suggestion. Well, I got it back working again, by charging it for 5 hours straight and then not charging it for an hour. Now it appears to be functioning alright, with the exception that it once went from 40% bat to 15% to 0% in a matter of seconds and I had to repeat the procedure to get it back on. I have another turbo with a broken digi that I could cannibalize but I have no idea what to replace... the battery? Bizarre issue, but I guess that comes with the territory of water damage.

Maybe some part is still wet. If another Turbo has only broken screen, then is probably the easiest solution to take screen from the (ex)wet and put to another one. You just have to have proper screwdriver.

Replaced battery now Droid turbo flashing when I charge?
