Hi, I seem to have found a critical issue...
so I was just normally charging my device, when I inserted the cable it charged normally, so I let it charge, but somehow it fried itself and after I checked back on it in about half an hour turned out it completely bricked itself. Nothing could turn it on. Either the screen fried itself or the phone was entirely fried, but there was no smell and neither the phone or cable was warm. Now I have to send it back to China and get it fixed since they only sell this thing in China...
Anyone experience similar issues? This was so sudden and without any warning.
Update:
My Xiaomi has arrived back from China and it has been fixed. Seems like a battery issue/charging issue as it booted up after like 15 minutes of charging. The battery has been replaced.

For past few days, I'm facing this strange problem that the phone doesn't charge beyond a particular limit, and sometimes at all. When I plug in the charger, it displays 'Charging' but the battery level doesn't go up. I tried few things to understand where's the problem:
1.) I changed the charger and used the other ones (700mA, 500mA, USB charging with PC) and they worked well for a while, although slow charging, but afterwards the issue re-appeared and phone stopped charging even by them.
2.) I changed the battery, thinking it's a battery issue. The one that I got from a friend charged perfectly well with my own MMX charger for the first time, but now it's giving the same issue again and not charging beyond a particular level, say 40%, which will eventually come down and it won't charge at all.
I'm confused as what kind of problem it might be - hardware issue with the charging socket, charger/USB cable issue, or a firmware issue? Has anyone faced this problem till now wherein the their phone doesn't charge, even though it shows 'charging'? Please share what did you do to resolve it. I'm currently located at a remote place and cannot visit a service center.
how old is your device? if it's more than 9 months you might have to replace your battery. you could find it on ebay.
Ok so I wanted to upgrade from Jellybean to KitKat today, with Bam-Rom.
I am preatty familiar with flashing roms. But I somehow got my phone to keep on rebooting. I wanted the battery to die, so I guesed I would leave it there drain and then replace the battery (I've got 3). After the phone "died" I replaced the battery and tried to open it. But nothing happens!!!
I've tried all of my 3 batteries, plugging in the cable, tried to boot into recovery and download mode. Nothing happens!
Is it possible that from the multyple reboots (about 15 min maybe) the CPU overheated and got burned?? Is there something I can do to check?
Any advice very much apreciated!!
Charge the battery for half an hour and try again
Done, nothing happens, pluging the cable dosent do anything. However I have an external charger so I know it is charging correctly. Also while I charge with cable nothing happens but the back of the phone get heated so I know the battery is charging that way too
I have opened the phone nothing seems to be burned or damaged what so ever
Replace motherboard. As to exactly what's dead on the board, unless you know how to work with electronics like that/how to diagnose problems (with gear like a multimeter), you're not going to be able to figure out exactly what died. And even if you could, it's irrelevant. You're still replacing the board if you want to fix it.
So I got my MX4 yesterday, opened it like a kid at Christmas. But weirdly the battery won't charge while the phone is turned on.
I left it overnight plugged in to a good charger and turned on, and it didn't even raise 1%. But when I turn it off and connect to a charger it charges with no issues.
I suspect this isn't hardware related due to the fact that it charges fine when turned off.
Anyone have any ideas?
In my case, it was a software problem that has been since fixed with OTA-5.
The battery percentage displayed used to be on the fritz but it's all good now so look for that system update in the settings and let us know if the issue remains
Thanks for the reply!
It's not just a battery % issue though, because it's actually not charging when it's turned on. Like I said if I turn it off and charge it it charges like normal and it starts from the % it was saying it was in the OS.
I do have OTA 5, but I think I might try flashing to Devel and back, or resetting the phone.
Thanks,
For me, I wouldn't see a difference in percentage until I rebooted the device :/
Don't hesitate to contact Meizu's customer service depending on the outcome
Hi everyone, I got a poco f1 from a friend. He used it quite normally. The cellphone was off for about a month - it didn't work. After a month I tried to start it however unsuccessfully, poco f1 is dead, I tried to charge it but it can't. What could be a malfunction? Help if you know and thank you very much
First, try using a different charging cable and brick. If it doesn't charge, Check if it can be read using a computer or laptop. If it still doesn't work, then the issue may be the charging port. If that's the case, if you are still covered by warranty, then go to xiaomi store. If not covered, go to a proper technician.
Btw if the device can be read on a computer, then it may just be a boot issue. Just flash again.
Does the white charging led light up when it's on charge?
If not, have you tried leaving it on charge for an extended period?
I've had difficulties with phones in the past after batteries have fullly discharged - eg the Moto G5 had some battery protection "feature" that stopped it starting up if it thought the battery was fully discharged - it was a bit over sensitive so would sometimes assume the phone was fully discharged when it wasn't
Try leaving it on charge for 24 hours or so then holding down the power button for for at least 20 seconds with it still on charge
If you have no luck and the warranty is out, get to a repair shop (or disconnect and reconnect the battery if you're confident to open it up - for a while I was getting sporadic shutdowns with my F1, following which it wouldn't take any charge, the battery light staying off when plugged in. This was all fixed by tightening the screws securing the black motherboard plate, the cover which retains all the connectors - not sure why but it seemed something, I suspect the antenna connection, had come loose. Since doing this about 5 months ago I've had no further shutdowns and my phone is usable again, having been completely unreliable before)
One trick that worked on some old Nokia phones was to charge it plugged to a computer instead of plugged to a charger - but as said elsewhere, if the battery is completely dead, YMMV.
Also, try to press and hold the power button and while doing that, plug the phone to the charger and then release the power button.

I guess your battery is dead
I have same issue, however I think my one is a motherboard charging IC issue. Does anyone know a way I can get it cheap from India, as I’m in the UK. India have it for around 9999 rupees which is about £10(+international shipping). I’ve ordered a charging port replacement from AliExpress to see if that solves the problem. However I don’t think that will work. No idea how my motherboard got damaged in the first place. I replaced a cracked screen myself and the phone was working fine for a few weeks, then it stopped charging all of a sudden. My PC also detects it/can access files doesn’t charge it. A new battery powered powered on the phone but again didn’t charge. Tried different adapters and cables too. Any experts out there know whether this is a motherboard issue or just a charging port issue?
If the phone is OFF for a month, then it is probable that the battery has gone down to a point that the BMS has shut it down. The BMS won't allow you to charge the battery because, in its own assessment, the battery is dead. Best way to test this case is to have another Pocophone with a good battery (or just a new battery altogether), detach the cable from that and test on yours. This may or may not work but this is one of the easiest to test and a new battery is easy to acquire.

Before you do that, just try leaving it in charge for 24hrs as suggested above, though it does look rather as if the OP has nicked off so won't be using any of these sage words!

yep mine also. i was playing genshin impact and suddenly it freeze and off. service center said it was dead motherboards.
Hello,
firstly i m sorry if this is the wrong section, i m new here.
Now to the issue. I have a Huawei P30 Lite with broken LCD. I replaced the LCD with an original Huawei service pack which included LCD, Frame, Earpiece, Battery, buttons etc. Basically it included everything except motherboard, charging board and coaxial cable. The problem is that after the replacement the phone is not charging. At first it was showing that it was charging without any success (% going down instead of up). After the phone battery drained, there is no charging at all.
Doing a full hardware check i noticed that there was indication of water damage on the charging port. I replaced the whole charging board. Still same result.
Reinstalled the old LCD pack (battery had some juice in it still for testing) with the same results. When the phone is turned on, i get a charging signal and the LED indicator but without actual charging. When phone is turned off i dont even get the LED indication of charging.
Steps i already took to save time:
Changed the charger. Used up to 2.1A charger with fast charge cable aswell.
Changed the charging board.
Tried both new and old battery, internal connectors etc
Cleaned the whole motherboard with alcohol to get rid of any debris even though there is nothing visible
The phone was working normally before the lcd replacement.
The phone is working perfectly with the remaining battery and was working perfectly until the new battery drained aswell. Only problem is the charging.
Cannot perform cache cleaning since battery is dead
Software upgrades, reinstalling etc will certainly not be of any help since the phone is not charging when turned off.
I am trying to avoid costly and time consuming repairs since the only fault i can assume anymore is human error which most likely i would have noticed during the repair. I cant accept that the main board died suddenly after a simple 2 part replacement and the only thing affected was the one that had water indication on it which didnt affect it so far.
I am looking for any kind of ideas since i am totally out of them.
thank you for listening.
Hey, i know its 1 year later but i wanted to ask you about this. I had the exact same problem as you with a p30 lite aswell. Did you find out where was the problem? Could you fix it? Thanks
