i've tried all the power + volume combos...how did you get to bootloader?

If people just let their phones charge undisturbed overnight and tried the next day to boot, that number would be -80%..

I bricked my N4 by accidentally flashing a wrong bootloader - a simple error that proved fatal!

That would brick basically any phone. You don't play around with flashing the bootloader unless you're sure.

Got the red light once while doing benchmarks.. But i was able to get into bootloader mode reflash system img.And bam i was good to go..

Dang man, this same problem is happening to the LG Optimus G. There is a thread on xda for that phone and the op says to take the back cover off, disconnect the battery then reconnect it and that fixes it. Maybe worth a shot on the nexus.?? That is if you don't want to reflash the phone.

Why you want to do it the hard way that void the warranty than the easy way?

I plugged on my friend's car charger and suddenly my phone turned off and wont turn on.
When I plug on charger or USB and keep holding power, red led blinks many times, faster and faster.
My computer wont recognizes it.
Any solution?

Holy crap. It's literally IN THIS THREAD.
Leave it on your charger for several hours and see if it boots. If not, it's probably RMA time.

It's plugged for about 10 hours and nothing.
I live in Brazil, no sells here yet and it was bought on USA.

I was just mentioning other options just in case someone couldn't get into the bootloader. What if you send the phone to lg because you couldn't get into the bootloader to reflash and they can by disconnecting the battery and find out that you are unlocked and rooted when the phone boots back up, which would also void your warranty. Although I would not take the back cover off if the phone was stock, might as well send the phone back if you can't get it to boot.

I am in exactly the same situation as you. Prospects to resuscitate our bricked Nexus 4 are extremely dim!

Im wondering if what is posted Here may cause this issue?
Please, any advice will be thanked.

You seem to know very little about how chargers, batteries and charging circuitry works. To put your mind at ease, a USB 2.0 port is rated at 5V DC, 500mA. That will charge a Nexus 4, albeit slowly. Your 0.7A charger isn't going to fry anything, as there are multiple safeties built in, unless something is SEVERELY wrong with it, meaning faulty construction.

So you are telling me that, unless there is any issue with the charger (faulty construction) there is no reason to worry about that it will lead to this "Red light of death" or any other issue (lowering battery lifetime for example)?
This is totally off topic but, Do you (personally) think it's true what people say that charging a cellphone with a lower output charger increases its battery service?

Quick question:
Does this red light issue appear when battery is drain to 0% (among other factors)

There is no reason to worry unless the charger or your phone is faulty, in other words, hardware failure on either side. Unfortunately there would be no easy to foresee that.
The charging circuitry will only use what it needs to do it's job. As long as the voltage is within range and the current is not too LOW, you're OK. The N4 is rated at 900 mA to perform a standard charge. It will accept as low as approx. 500 mA to charge in USB mode. That idea is rubbish.

[Q] Nexus 4 taking FOREVER to charge

I've had my Nexus 4 for about 2 weeks now and currently it is taking a ridiculously long time to charge. It has been hooked up with the original USB to Micro-USB cable for about 3 hours at it went from 12% to 8% (wtf...) to 10% now and hasn't moved for the past hour. Someone help please
Try charging it from another charger it or a PC. Sounds like your charger is probably faulty.

Yeah you could try a factory reset. Failing that, re-flash the stock ROM. Failing that, RMA it.

I'm not entirely sure wether this is a "good" answer but are you charging by USB meaning plugged in your computer or laptop?
Because I've had it with several phones that if you put it in your laptop it doesn't charge or very very slowly. In the PC it goes faster but not as fast as straight from the wall.
Try plugging the charger in a wallplug, see if that helps? And also if you really want to charge by PC, flash a kernel (see Franco's thread) and put it on "Fast charge USB", then it should go at the same speed as wallcharged. (dunno how on stock rom)
-------------
If you meant that you've charged by plugging it into the wall in OP, then I'm sorry, I don't know Or just a faulty charger.
Daydream
disable daydream (while charging)
This also happens to me and I found out that when I plug my phone wall charger, in the battery menu it shows that the phone is charging using "USB" instead of“AC".....any help?

Do you have a custom kernel installed? Maybe there is a faulty setting in there. Worst case scenario is RMA, but try having the phone plugged in and then power the phone down. Once it's off, press the power button (don't hold it) and see if a battery animation comes up. If it does, then keep it plugged in for a few hours and see if it charges any faster...
try a different cable. For me, the cable went bad. when connected to the oem wall wart, my phone would sometimes be charging USB, sometimes A/C. After changing the cable (not the wart), always charges A/C now.
Install a battery utility and verify how much current it is drawing.

Nexus 4 charging very slow

Hi so my nexus 4 is charging very slowy, I've this phone for 1 year and I don't know what's happening...Also that might explain (why but)...... if its because of my charger or what. But I need help like I'm just wondering why this is happening? Thanks. Also I don't know if this is happening because of the 4.4 update or something lol?

Apparently something is wrong if you see it charging slowly becoming ever since day one, I've felt that it charges really slow!
The only way to test your theory is to downgrade and see what happens. (as far as the upgrade is concerned)
If you have another charger, obviously that would help as well to see if the n4 charger is shot.

I have recently started seeing this problem as well. I even tired a different kernel thinking maybe that would solve it, but to no avail.
I will try with a different charger and see if that would help.

When you go to the battery history (from quick settings for example), does it show (constantly or alternating) USB charging when lugged to wall socket? When i had this, i changed my USB charging cable (the charger is ok but the cable died quickly)
Charging slow is usually due to the charger, try another one that is at least 1A output (original charger is 1.2). Nokia ac-10x is perfect and pretty cheap.
Other causes can be bad charging port or sometimes even a battery drain caused by software.
Whenever you plug in the charger make sure that your Phone shows "Charging (AC)" in your battery setting. If it says "Charging (USB)" then unplug and replug it again. Keep doing until it shows "Charging (AC)"...... On USB charging it charges at 500mA which is half the charging speed of AC charging. I had this issue and I am doing the same to charge it quickly. It doesn't take more than 2h 15mins to charge.

[Q] Dead battery

So Ive had my Nexus 4 since it came out with no problems until now, when i place it on charge it stays at 0% no matter how long its charging for with USB and AC. Is there anyway to fix it like elaving it charging for a few days in hope it eventually charges or is it just a fancy brick when not connected to power? Also my warranty is out so not able to exchange it.
Same problem, somebody help please. :/
Have you tried a different charger?
Does the phone actually turn on? Do you get any response at all from it?

The phone won't turn on, it's like dead. I tried different cable, but it haven't work.

You may have the dead battery problem that has been mentioned before in the forums, do a search for nexus 4 red light of death, there are a number of solutions, some might work, others might not, but that is my best guess

Heating problem

Last night I've put my phone to charge until morning, and I've put the phone under a pillow because I have a one person bed and I don't want to hit it with my legs. In the morning, when I took the phone out....
The phone was extremely HOT! And I know where the parts are in this phone, and not the motherboard heatead up so much, the battery! I was so scared because this thing could explode in my hands or could've exploded last night.
Also, when I saw the phone the notification led was blinking blue, but after cooling the phone I couldn't see any notification. Is that a alert or something to say that your phone is hot?
I don't want to have a "note 7" clone when charging in my house.
I have this phone for just 6 months. Also the battery right now drops percent like per minute, really weak.
Does anyone had this problem too?
Here are screenshots:
Also, I am not using original charger because was too slow. I am using an 5V 2A charger. Now my battery stays at "normal" at 40C°
Is that normal?

I have found this in my manual. I will keep my eyes all day on my phone and will see if I will go to the service or not.
But I have bootloader unlocked, the phone was disassembled before, the water indicator is red, so I'm going to have to pay.
It happened to me. One thing I noticed that my phone was in wake lock. It never happened to me again. I think I was using LOS 14 at that time.

Every phone has heating problems. Few days ago i readed some articles and that stated: consumers should remove the custom cases when charging the phone. Do not keep your phone while charging on surfaces that stores heat (eg. your pillow), and try to not keep your phone on charge overnight. Even if its at 35-45% you should leave it so and wake up 30 min earlier every morning and charge again if you need more battery. 100% charge its not a good idea.
Remember you cant change battery easy, removing the back case its a pain, try to take care of your device, or you gonna buy a new phone soon

Of course not......You are using 2A charger.....It would obviously heat your device up
and yes ......2 A charger won't help with speeding up charging it would burn your IC instead..Your phone won't take in more than 1 Amp thats a factory limit and can't be unlocked without a custom kernel but still it's not safe.. Don't use that charger .....It's a placeboo that it charges faster ?

x720 battery empty, can't charge

Hello everyone
I have a coolpad cool s1, virtually identical to the le pro3 x720. Stock rom (version 19. something if I remember correctly, default one from grossoshop), rooted.
The other day, the battery was 3%. I plugged it in the charger when I went to sleep and it didn't show charging. I didn't make a big deal out of it, because the power extension cable has bad contact. Thought I would figure it out the next day. Next day I couldn't get it to charge in other plug. Phone has since died. At first, the red indicator light would blink whenever I would plug it into a charger, now it doesnt even do that anymore. I've tried about 5 different adapters (quick charge, non quick charge, laptop) and 3 different cables. I've tried holding down pretty much every combination of buttons for two minutes, in the charger, out of the charger, just before charging. I can't get the phone to do anything at all. When its in the charger its still very cold so I assume its not charging at all.
I've seen some other posts on here, but none really offered me a working solution. I've tried to get the phone in qualcomm recovery mode, but laptop is not detecting any device.
I've had the phone in use for about half a year, I can send it back if I want but it takes long time and I would like to keep my data if possible. Any suggestions? Phone is a literal brick right now.
Here could be part of the problem it is not a leeco le pro3.
You should be not flashing are ROMs on it.
At best try different cables it may not work at all because you flashed are ROMs on it.

Get new cable let it charge around two hours.
Then unplug a then press power up to one minute repeat if needed.
If this don't work battery may be dead.
Never let your battery go under 15%.

I've tried this several times with a third party cable, with multiple adapters. No result. I normally always charge my battery when I can, but I had just come home from a trip. So the images I took were not synced yet either
One last thing to try will your battery show charging?
Hold down power bottom and plug charging cable hold for 30 seconds.
If this fails you could have bad battery.
Try this hold volume up and down and hold down power button same time and plug in charger hold for 30 seconds.

Well, don't be too worried. Replacing the battery on this phone is a fairly straightforward process. It has the same internals as other LeEco phones: http://www.myfixguide.com/manual/leeco-le-pro-3-teardown/
Also, never ever let a lithium-ion battery, AKA any smartphone battery drop to less than 15%. You'll ruin the battery for good that way.

I try my best not to when I can
The thing is, the battery still had excellent capacity before this happened. I don't understand that it would be broken, seems more likely that something with the charging circuit is broken. Or I found 1 guy on a youtube video who had seemingly exactly the same problem and claims that just disconnecting and reconnecting the battery will fix it.
The phone is only half a year old and bought from within europe from reseller, I contacted grossoshop and they say they will RMA, but I don't want to be without good phone for two months, will have to consider my options..
Or if anyone here comes up with any revival suggestions that would be even better

Not wanting to take a heatgun to my phone, I ended up sending it back over warranty. If I knew that they would take so much longer than promised, I would have fixed it myself
Also the warranty note from what I assume comes from leeco itself, they claim to have replaced battery + charger circuitry + charger itself.
I do have to add that since it returned from warranty, I could not get my phone to charge using any of the android 8 roms so I'm stuck with an android 7 rom :s

You could try using an EDL cable such as this one: https://www.amazon.com/MagiDeal-Qua...-4&keywords=EDL+cable+for+all+Qualcomm++usb+c
Also the 4PDA website has a whole section dedicated to this phone. You may get some better feedback there. Even though the S1 is pretty much the same phone as the Leeco, Leeco users will not relate to the steps you took to turn it into a leeco pro 3. Next, one resolved you may consider using the most Miui roms, ( see last few pages of miui thread) The Ares rom uses S1 fingerprints, and the S1 Vulkan kernel, I enjoyed that Rom quite a bit, until I found dotOS, which is better.
Thank you for the reply, I had seen your reply but I was in a pretty busy period so I just decided to just roll with the android 7 rom for a while. However recently I've decided to give it another shot, I would really like to have that aospextended rom
