[Q] Charging oddities while phone is off

Hi,
Last year my girlfriend allowed me to root her Sensation to try out different ROMs and all went well. A few months ago however, she started to have problems while charging her phone.
If she plugs it in while the phone is closed, the orange LED flashes on/off at around a 2 second interval, instead of holding it's colour. Furthermore, it never changes to green to indicate that the charge is complete. When the phone is in this state, she can't turn her phone on either - she has to unplug it in order to turn it on. If the phone is already on, and she plugs it in, everything behaves normally.
Either than that, the battery seems to hold the charge normally and the rest of the phone still works very well.
I've tried searching for similar problems but haven't landed on anything similar or which may be helpful. It's really got me stumped to what could be the cause, and more importantly, how to fix it!
Would someone have any ideas?
Thanks!

Does the phone behaves in same manner if it's fully charge n switched off when plugged to the charger.does the orange led fluctuate.
The orange led fluctuate whn the voltage of charger is less and it takes times to charge try switching the charger means if you use wall charger then charge through pc and vice versa

We tried switching from wall plug to USB on the laptop and it does the same thing. However, we noticed that if the battery isn't completely drained, the led doesn't flash - it charges normally.
Would there be a way around this?

I'd pick on the odds that the LED light hardware controller is slightly faulty, but if its really like you said its nothing to worry about, right?

Hi,
greetings
this used to happen with me when i was on stock rom.
the problem is when the battery is completely drained it needs lots of voltage to get charge
for this problem i took my cell to htc service center and they replaced the adapter and the problem was solved
i think you must buy a new adapter or say a new charger i thing that must solve your problem of led and your phone will get charge as normal even with the battery completely drained OR i think we get wall chargers you can look at the picture in which we have to place the battery and the battery gets charged you justt have to put the battery.. this charger is locally available in indian market for 80 to 100 rs.. you can search on net for the charger this is really a good thing and is a universal charger chagers each and every battery here in india we call it as khekda (marathi word for carb ) charger
let me know if it does solve your battery

[Q] Nexus 5 -- Blinking red light?

Hello,
So I was playing around flashing roms from here last night, and I was able to load up a rom that I liked, and get it configured to my liking. I noticed while doing that the phone started to get really hot. I didn't think anything of it, and left it on the charger and went to bed. This morning I woke up and the phone has a blinking red light. I did some Googling and it said that it was a completely drained battery. So I put it back on the charger and now the phone was able to boot back up, it says charging, but it is just at 0% and it doesn't seem to go anywhere from there (plugged in via computer) any ideas?

Revert to stock and see if it still acts like this?
A friend of mine had the same blinking red led.
Turned out the battery was completely drained.
After charging it for a while it was fine again.

Yup! It was drained, and it wasn't charging when I posted this when I had it plugged into my computer.
I put it on the wall charger and left it set for a few minutes, and then it showed up at 7% so I'm really relieved I didn't brick my phone. I just don't get why it didnt charge last night, I know I plugged it in...

Yeah that's strange behavior. My dad was playing a game on his N7 which was hooked up to his PC when it suddenly died.
Scared the hell out of him, turned out it hadn't been charging through USB for some reason, or maybe not enough.
Weird about last night. Maybe it wasn't plugged in completely. Have you tried the same socket? Maybe it's dead.

The computer charges android devices really slowly. When you're playing a game, it will drain faster than it charges, especially if you charge it by a PC/Mac and not a main power source

Blinking Red light??
Dnt worry this indicates that your phonr is just on the verge of its battery
just keep plugged in in for few minutes
now the light will stop blinking and you will get the battery level icon on your screen
Hope this helps you :angel:

But this never happened to me ealier while using a charger,Today i used just a cable to charge it and i behaved so.Is it because the charge it was getting was less to sustain or do i need to get it checked ?

i have this problem too i evan had it charged for an hour and a half and still no nothing evan started it up on the charger and it still does it i dont know what to do

Is the led still blinking after 1.5 hours on the charger? Maybe try a more powerful charger? Different USB cable?
The USB cable and charger that came with the phone is what I would start with to charge the phone.

Just had the same problem after not charging the phone for 10 months (broke while I was travelling). Just got it working after I ordered and installed a screen replacement from Alibaba. Needed to try 3 different USB Cables.

Maybe just a different USB cable would have solved the problem?

Charging via a computer is the last thing to do. The output is so low.

Hi guys,
I'm having the same problem. My phone has been charging for about twelve hours now and it still won't turn on. I tried using different outlets, but not a different charger since I only have one (original one) and my friends phone did charge with that charger. I also tried pressing the power- and volume button at the same time, but still nothing. Everytime I take my phone out of the charger and plug it in again, the red light starts blinking for a while but then it dies off and nothing happens anymore. Does anyone have anymore tips?
Thanks

Sounds like the battery needs to be replaced or you need a more powerful charger.

i've got this problem except anytime a charging cable is connected, the phone powers on and off continually as if the power button is stuck. tried swapping batteries with a spare n5 i have with a cracked screen and bad IMEI (lousy ebay purchase), made no difference. same thing occurs even with battery disconnected. there's no way to boot into recovery. the red LED blinks when the phone powers off momentarily. tried various cables to charge, multiple locations. any ideas?

Saved me!!
Saved my nexus 5, i love this phone and don't want to lose it even after three years passed way!
thankyou brother you nailed it.

[Q] Black screen but charging led lights up

Hi There,
Yesterday morning I went to work with a completely charged Moto G. When I arrived at work my screen was black and had become unresponsive.
The powerbutton doesn't wake up the phone, tried several times, holding it for more than 150sec. When connected to a charger (tried multipe) the charging led lights up, not blinking.
I have read on a motorola forum that this could indicate that there's insufficient power in the battery to activate the display.
However it was completely charged.
My Moto G has an unlocked bootloader, is rooted and has a custom rom (C-Rom, [ROM][AOSP][KK][12/05] **C-RoM** -4.4.2- -v6.5)
Is there anything I can try or is my phone a brick now?
Thanx in advance

The same problem
I am having the same problem too.
My moto G drained its battery until it shut down. Then i promptly went to charge it. The screen is blank and and notification light is on.
snooze1973 did u find a solution or is it now working?
PS My Moto g bootloader unlocked, stock rom,rooted and it is on the Faux123kernel
Thanks in advance

No luck Yet
No luck yet, left it on the charger for a whole night, still just the white charging led. No response to the power button.
But I refuse to believe it is completely dead. Before I had a HTC Desire S, tried many custom roms, never bricked it.
I just can't imagine what happend the day before yesterday.
Perhaps I'll try and find a more powerfull charger.

I think I found a solution. I followed these steps
1. Charge your phone via USB cable on your computer.
2. The white notification light should come on.
3. Then, do not touch any buttons on your phone.
4 The iconic Battery Logo(white background) should appear after several minutes.
Followed these steps and my phone eventually turned on
Good luck!!

Still no luck, trying a different cable (blackberry) now.

Not working for me, still just a beautiful white led indicator.
Start to think it's probably dead. Or battery thinks it's drained somehow.
Maybe anyone else has an idea?

Ok, I opened the Moto G and disconnected the battery, reconnected it after 10 sec. still no luck
Odd thing though and not very promising is that when the battery is disconnected the charging led still lights up when charger is connected.
Could this just mean that only the battery is fully drained or that the device is messed up?
Guess I going for a new one.

See if a new battery helps

Bought a new one today, so I can try and fix the other. First I will leave it for at least 24 hours.
Perhaps I will exchange the batteries at one time to see if that helps.

Black screen but charging led lights up
I am experiencing the same issue.
I bought a dead moto g for part replacement with my current moto g. Just out of curiosity, I plugged in the charger to the newly arrived moto g and observed the similar behavior.
To go further, I swapped the battery and tried to turn it on, and voila, it boots!! It has C-ROM. But it won't charge the battery any how. Its again back to
original behavior : No Screen, No Battery Charging, Only notification LED glows. I kept it on charger for whole night, but no luck.
The notification LED turns on even if I the battery is removed and charger is plugged in. What does that really mean?
Is there a probability that the charging circuit is broken? or it has something to do with bootloader, C-ROM and custom kernel? Does any one thinks reverting back to Stock ROM will help out in any way?

Same here...
Exactly the same with my little brother his Moto G 4G (1st gen) (stock rom, BL unlocked & rooted).
Solid white LED when plugged in, no other response.
The most advertised trick does not work (step 6: flashboot screen doesn't show up)
[SIZE=+1]Q28: Moto G will not power up (addition to Q16 and Q25)[/SIZE]
Plug it into the charger
Hold the VOL DOWN key
While still holding the VOL DOWN key, press and hold the POWER key
Hold both keys down for over 120 seconds. This is more than two minutes and will seem like a long time. You might want to time yourself to make sure you hold it longer than two minutes.
After holding the keys down for more than two minutes, release them.
The Flash Boot screen will display, and the Normal Reboot option will be highlighted
Press the VOL UP key and the device will start a normal reboot.
If you have tried the above and it didn't work, try this:
Plug in the phone for 15 minutes.
Proceed to Step 2 above.

It has been an hour on the charger of my Asus T100 Tablet (5V, 2A). Still no luck...
Due to the lack of other solutions, I guess all our phones are ready for RMA...
Update: an overnight charge on a 5V 1A charger did the trick. White led was gone this morning, booted normally.

I don't know why a USB charger and a PC connection should make any difference when the phone is not booted up.

I had the same problem. I solved it by removing the battery by opening the phone (mine was out of warranty) and taking it to repair shop where they charged the battery for an hour. Then when I put it back in, the phone rebooted normally with 10% charge.
But ever since, my battery life has deteriorated. Doesn't even last one full day. And I have had the same issue twice. I think I need a new battery.

I have a simple solution for that I have faced this issue long time ago and now I know a permanent solution. You all have usb cables in your house...just took a old one and cut it from the mini usb side..there are 4 wires...you have to care about red and black..open your moto g battery and took it off from the phone now connect the usb cable to your pc and touch the red wire to the positive and black to the negative ...just do this for 45 seconds and immediately connect the battery to the phone and connect the charger...phone will starts charging from 0 % pls do not wait to connect the switch and back cover just charge it upto 20 % the cover it up.....DO NOT LET YOUR BATTERY DRAIN MORE THAN 30% AS THIS IS COMMON PROBLEM IN LI ION BATTERIES...

Interesting, but how did you determine the negative and positive terminals on the battery flex? Can you, please, mark the attached photo of the battery of moto g to help the community?
Also, as a side note I think I discovered a solution - I connected the phone to my PC's usb 2.0 port and held the power button for 2 minutes - at which the LED blinked momentarily and then continues to shine. I left the phone connected and continued to browse for solutions to this battery charging dilemma - then about 5 minutes the LED stopped shining (and I breathed a sigh :silly: !!! becaue this is the sign of battery being charged!) and after about 30 minutes of charging I turned the phone on and it was 16% charged. Well I haven't been able to reproduce this solution (since, I have been extra cautious with the battery now!) but I would surely like to know if anyone can reproduce this solution:
1. Plug in your phone to USB 2.0 or 3.0 port with original moto g cable and confirm that the LED shines continuously.
2. Hold the power button for 2 minutes (which I discovered to be a long time if you just continuously stare at the phone!) after which you will notice that the led with blink momentarily before continuing to shine continuously. (I suggest you continue holding it for another 2 minutes after which the led will blink again momentarily)
3. Leave the power button and leave the phone attached to the port for at least 30 mins before attempting to power on.

Sony Xperia Z3 (D6616) - Sudden Death

Was accessing dual recovery to wipe for a clean slate and it had a sudden death. The charging LED was no longer lit. Left the phone alone for about 2 weeks to let it drain but no response. Decided to order another battery for testing thinking it may have been bad, still no response. What I did notice is that if the battery is removed and the charger is connected, the LED blinks red constantly. However, if I were to attach the battery connector the LED will stop blinking after a few seconds. Is this an issue with the motherboard itself or can there something be done to bring it back to life?
*Update*
Let it charge for a couple of hours. Still not turning on but getting some response at least. The phone will now vibrate in sets of 3's if I hold down Power and Volume +. When trying to charge, the red LED will come on for 5 seconds then off every 5 seconds. When connected to the PC, it shows as unidentified USB, but the sound of it being disconnected is constantly going off. Not sure if anyone knows how I should proceed from here...

Hi my phone is a D6603 and i was having a very and inusual problem like you Sudden death with some response vibrating in sets of 3's. My problem was resolve when i remove the sim then press the reset button 2 times in a row but slowly and the phone was starting again
I dont remember if it was or not conected try both ways
Back up your files and start working to keep it warm and dry, remember that it can be water damage. I downloaded minergate and began to mine in easy difficulty so that it would not become slow, but at the same time to keep it warm. It is only to dry if it was damaged by water, I do not recommend anyone to mine with a smartphone xD

Nexus 5 won't boot, 8 blinks

I have never had any problem with my Nexus 5. It is now my standby device. Accordingly it doesn't get used much. One day I left it ON and didn't use it for 2 weeks. When I picked it up again it was OFF and didn't want to turn on. Naturally I thought the battery had drained and put it to charge.
Instead of the battery symbol on the screen (indicating it is being charged), I get a sequence of 8 red blinks on the bottom notification light (which is just above the charging port), each blink lasting 0.5 seconds, then 0.5 seconds off (so total duration of blinking sequence is 8 seconds), then 1.5 seconds off, then blinking sequence starts again.
I left it connected to the charger for 2 weeks. Nothing changed.
I then replaced the battery with a brand new OEM battery, same thing again.
I cannot get into recovery mode nor is the phone recognised when I connect it to the PC.
Any ideas? Anyone knows the meaning of this blinking sequence?

what is the current state of the phone? do you just get the blinking when charge cable connected? no boot loop ?

So currently the phone doesn't switch on and cannot be charged it would seem.
There is no bootloop.
And yes, the blinking only goes on whilst a charging lead is connected or whilst it's on a wireless charging cradle. No blinking when removed from the charger.

you said you replaced the battery , I would check that connection , try removing the battery if possible and reconnecting it. Try the old battery too if you still have .
In my experience i'v seen that blinking light in other devices when they overheat.

I only replaced the battery because of the blinking problem as I suspected a deep discharged battery. Anyway the connections are good. 100%.
I never had overheat issues on my N5 as it was just used for basic functions, no gaming etc. I wouldn't imagine the device had overheated while it was left unattended on my desk, and there definitely is no overheating happening now as it doesn't even switch on...

sounds like your hammerhead finally checked out ... the old saying goes " if you don't use it, you lose it " .... try all combinations like hold power and volume down at the same time for 10 seconds , power and volume up ..etc
other than that i'd take a multi meter and make absolute sure you have power to the motherboard , then if you still do, it could be a short ..
if you want to go even further, a complete tear down of the phone, check for corrosion ( whitish residue on terminals and motherboard ) clean off with toothbrush only ( no water or liquid of any kind ) be careful removing ribbon cables and re-inserting them ... you can find lots of stuff on youtube for that.
good luck
