wall charger not working

I have a Moto G bricked on moto logo and i tried to charge my phone on a wall charger and laptop
Charging my phone( turned off ) on wall charger = white screen appears showing 0% and it never changes
Charging my phone( turned off ) on a laptop = white screen appears showing 0% and 10 min later it turns on automatically and stucks on moto logo( cause my phone is bricked)
Charging my phone( on fastboot mode ) on wall charger = it shows ''Battery Low'' only, not charging
Charging my phone( on fastboot mode ) on a laptop = it shows ''Battery Low ( Charging )'', but 0% forever and surely it will never change
I've already tried using my official charger and universal USB
Even Worse!!!!!!!

Try to leave the phone in charge (using pc) for at least 2-3 hours, then check again. If still doesn't work you could try to open the phone to unplug the battery, putting it to the fridge for 15 min, then plug it again and try to charge (use this thread)

And the battery is still low?
Hi, having the same problem as the original poster.
Right now I'm trying to charge the phone from fastboot, connected to a PC ( wall charger does nothing exactly like op's case).
I'll wait a couple of hours and try to boot it again, hopefully it will have enough charge then?
I've noticed that ''Battery Low ( Charging )'' will change to ''Battery OK ( Charging )'' if I select the "Barcodes" menu voice and then go back to fastboot from that section by pressing volume up/down, not sure if that helps anything...
My phone is fully original software, no mods at all. It started doing this when I was recording a video, the phone suddenly crashed and started going in boot loop berserker mode.

Does your pc detect anything when you plug usb cable ?
Yes, it detects, but then disconnects, can it be a problem in the battery?
Chances are you have received a refurbished device or defective battery.
Try and find another Mi4 user for trial of the battery or let's see you need to contact the vendor soon.

Charge via wall adapter. Leave it for some time.
PS: When your battery reaches 9-10%, it is advisable to charge it back to 100%.

I just got this issue 10min ago. Havn't depleted the battery on the phone for a very long time, my guess is that it hasn't calibrated the battery in a while or something like that. Will keep it in the fast charger during the night and then i'll reply here.
EDIT: Normally the red LED is constantly on when the battery is low and it's in the charger, now it's flashing which makes it look a bit more scary.
EDIT2: Works fine now after a night of charging
Charger could be not pushing enough voltage to charge battery. Try another one to see if it remedies the issue.
I do have the same problem with my Mi4. I wanted to start the update in the Updater app (to Android 6 version of Xiaomi.eu) and suddenly it turned off (at 100% battery). When I connect my phone with my computer it is recognized and all the partitions are mounted. And with all I mean all. There are about 7 partitions mounted (Linux and Windows) and they keep being mounted until I disconnect the phone. I let my Mi4 on the wall charger for 24 hours (2A Samsung one which charges all my other devices without any problems) but I still have the blinking red light after connecting it to the charger. Any other things I can do to get it running again?
EDIT: I can't see the phone in fastboot or adb and when I keep the power button pressed for about 10s it seems to disconnect and instantly reconnect the phone.

I solved this problem on my own. Even though the phone doesn't show up on the fastboot devices list you can use the Mi Flash Tool to flash the fastboot update (http://xiaomiadvices.com/miui-7-flash-fastboot-rom-on-xiaomi-phones-using-mi-flash-tool/). The drivers installed with the Mi Flash Tool for the Windows 10 Mobile Release (http://en.miui.com/thread-189369-1-1.html) recognize all the partitions as one device and show it with a cryptical name in the flash list.
Hi ! I fully charged the phone and after it shuted down. It doesn't starts. PC doesn't see it. When I'm plugin the wire just half way into the phone the red light stays on for a few seconds and than nothing at all. Can anyone help me?
Push power+vol up for quite enough lets say 20 sec
same problem here i kept charging for whole night but phone not getting on.. only red LED comes when kept for charging and not detected in PC also. Can any 1 help on this
I had the same problem ( strangely,it occured after a whole night charging, f... knows what happened)
Tried to change charger. No luck. The phone won't even boot by pushing Vol down+ Power
Solution: I simply connected the phone to a portable external charger, and tadaaaa !!! it was brought back to life !
Hope this helps

galaxy note 10.1 not charging + other devices...
first note .... I'm nt a developer or otherwise... but I have studied batteries for 3 years professionally ... and as I found out .. to re initialise your battery in this device ... ( I have done this several times ) you need to open the device and disconnect the battery... then reconnect it ... then just charge as nomal no special time ..button press needed ( for note 10.1 ) ... the problem arrises because the firmware cant boot with a flat battery correctly .. normally when a device is flat the firmware is set up to restart the devicwe when its re charged ... but if the device is left for a while or the battery is old .. 1 year plus ... ( yea its a fine threshold ) the device will not boot and end up in a loop or stuck on start up screen ... I have noticed his in a number of devices ...the only way out of it it is to charge the battery ... ...example in a nexus tablet you have to charge the battery via wires , inserted into the battery ( there are two ) ... then the device boots .. but if you let it go flat ... u have to repeat the process.. same in the note 10.1 ... you can actually charge the battery to full capacity as normal .. but the device still wont boot ( I verified this ) .. the only way round this is to charge it .. for a hour or so then .. open the device and disconnect the battery and reconnect ..... plenty tutorials on line ..easy to do ....3 screws and clip back off and disconnect ... reconnect .. charge and boot ... the prob seems to be as I said in the firmware in the device as when it was made tested they only used new battery's !! never a old one ... its one for developers to sort out ...oh btw I have not ever lost any data on the device ( photos .. accounts etc or anything by doing this ) hope this helps .. ...

Overnight Charging [Redmi 4 not Booting ]

I don't know what happened to my phone (Redmi 4), I kept it overnight for charge and when I woke up to check my phone , it wasn't turning on at all.
(I kept it switched off at night while it was charging). It wasn't the first time I charged my phone overnight.
Tried Trickle Charging ,it's sill not booting . Although now I am able to boot into fastboot mode.
Is there any chance it might have been bricked ?
Any solution or would I have to pay service station a visit ?
Also whenever I press and hold power button it flashes mi logo for less than a second and switches off , also the led which used to get on during charge isn't getting on.

MY XZ premium wont start with button

Hi Guys,
I have charged my phone XZ premium with non OEM cable
And sudently it siwtched off and i tried to start it without succes, i put the original cable and then the phone start charging but the strange thing is when i disconnect the cable and try to switch on the phone noting happen only when i put the charge and i wait for the phone to show the charging screen then i push the power button and the phone start.
Even when i try to restart my phone when the phone wont open ( like it was switched off and not restarted ) i do the same thing agin put on charge wait the screen and push the power to open the phone.
another thing the phone take 6 hours to be fully charged ( there is no more fast charging )

i wonder if someone could help me if its just the charging port will the replacement solve the problem or i have to use my phone this way and not take the risk of open the back of the phone and repalce the charging port.
thank you in advance
