MI A1 charging only when switched off or restarted - Xiaomi Mi A1 Questions & Answers

My Mi a1 updated the june security updates and entered bootloop. I had to open the phone and use edl method to flash the phone. When i was opening the phone using the charging port space it seems i distorted the charging pins.
After this, i had issues with charging sometimes and my phone could not transfer information from the computer. It later graduated and my phone right now does not charge unless it's switched off. I got a new charging port and replaced it, however the same conditions occur - my phone charged only when switched off. I checked online and noticed that for a mtk phone, we could use mtk engineering app to switch VBUS on but i did not see a solution for a snapdragon phone. I also noticed that if i disconnected the mainboard flex and reconnected it, my phone would charge normally.
I would appreciate any help in solving the issue. The phone is still fairly new but the charging issue is really bad.
Thanks

USB Charging issues / Computer does not recognize while on

So this issue happened out of no where after my phone died to zero last night. I tried charging it back up but all I could get out of it was the grey charging battery but it would only stay on for 1-2 seconds shut down and reboot. Let it charging for an hour and got to about 1-2% and it would die as soon as it booted up. Factory restored to OA6 and still see the same issue. This is also the odd thing... I was able to connect it to my computer and use Oden to do the restore! After lots of troubleshooting, trying 4 chargers, I realized wireless charging still works fine. Charged it up 100% over night and wireless charging is still working fine and phone is working fine. Still cannot get USB to be recognized while on either by computer or from USB charger. With a full battery, phone off, and USB plugged in phone still flashes the grey battery icon and reboots constantly.
Only thing I can think of is I had it in my pocket after spin class for a little and moisture might have gotten in the port?
Any ideas what happened here?
Update: I ended up just buying the Nexus 6P since I'm about due for a new phone anyways.
Well just figured I would pass this along. Was bored before and looked at diagrams to fix the USB board and saw this little port in the back you can access really easy. Decided to open that up and press the connection down a little tighter (the USB board is separate from the main board). USB didn't work before doing this, then pressed it tighter plugged USB in again and it worked.

Dead YD206

So YD206 about a month old. Was connected to official yota charger (via a magnetic usb cable), noticed the plug at the phone end getting quite hot. Phone now essentially dead, wont boot, doesn't seem to charge. We also realised the charger had come out of the wall socket. But the yotaphone light was intermittently flashing on the charger.
Whilst I am inclined to blame the magnetic charging cable, is it possible for current to flow in reverse from phone to charger and essentially discharge the phone battery below acceptable levels?
Any advice on rebooting it (can't remove the battery like I would on a Samsung) so whats the procedure?
Just a follow up charger not the issue, it crashed in use and the power button became non-responsive, with the screen off, and the e-ink display on but also unresponsive. Did not turn on when connected to a charger. However when I connected it to my pc it did register in device manager as MTP device, so I knew it was still alive. Removed the sim and held the power button down for 10 seconds then it rebooted.
Hope this helps anyone else with a similar problem.
Failing that it would probably have to be left to discharge (might take a while if nothing is running) then powered back on with charger attached.
I have similar problem. My phone got hot while not charging (about 15% of battery) and crashed. Then forced reboot (hold power button for about 10 seconds) helped while phone was connected to Yota charger, battery was dead, but phone booted (EPD on, did not check rest) and got to about 81%. After removing it from charger, same thing happened again, no luck with forced reboot this time. Phone was blazing hot and did not respond, then crashed again. No response after connecting charger or forced reboot. Any experience with this issue appreciated.

It seems a battery issue. Have your Yotaphone a valid warranty?

I am not sure about my warranty, bought it off AliExpress, I guess I could try to send it to manufacurer (i heard Russia provides repair service).
EDIT ( t + 2 days): I managed to start my Yota again. I connected it to computer and after about 5 minutes, magic happened and phone started all by itself. I will try to find out more, will update this as soon as I find something
Man, you are more lucky than me, I have a dead yotaphone lying around here. It also died after connecting it to a bad power source.
In my case it was the usb-port of a monitor.
When I checked the usb-port with a cable with a volt/amp display I saw that it was going on and off very quickly.
But so I would say be careful where you connect your yotaphone to, it does not seem to handle weird power sources all too well.

I actually thought about burning charging circuitry a lot. I wonder, if you would be able to test wireless charging. With some luck, it is independent enough to not be affected by burning micro usb charging route (depends where high voltage safety is implemented). If this make any sense to you, please give this a try (I think IKEA is place to go, they should have working wireless chargers in their model setups) and report back. If I am wrong in any aspect, I'd appreciate any correction with explanation.

Sorry for the late reply, did not see the quote, but it does not work with wireless charging either. I think the battery still has a lot of charge too. Thing is that the Motherboard also gets hot after a while when I try to charge it. I'm pretty sure my motherboard is dead. But I have another Yotaphone now, so maybe in the future I will test with every separable part replaced.
I use the charger from my iphone. It works great, although with the yotacharger also works well. Attention that I have a YotaPhone YD201 with Russian base and european compilation. Like I said the Iphone charger works great and doesn't warm my Yotaphone 2 . It might be a solution for your problems with charging.

Strange Problem with Charging my S8

Yesterday, my S8 said that there was moisture in the charge port. I look in there and saw that there was something in there, I tried to blow it out several times but managed wipe it out with a handkercheif. After that I swiped the notification and it didn't come back again.
At night time, I plugged my phone to the charger to see that after the phone's screen went off, it stopped charging to come back again when the phone screen turned on. It kept repeating this cycle. But when I unlocked the phone it continued to charge until the phone's screen turned off.
I changed the charger, it charged even when the screen was off. Also, it worked when I tried to use a powerbank. But when I used the packed in charger, it kept repeating the cycle.
Thinking that it might be a bug, I restarted the phone to see it's fixed.
I closed the phone to switch it on this morning. But before I switched it on I plugged the charger to see that it gave the "Drop" icon meaning that there is moisture in the port. Then I switched the phone on. The problem came back! It didn't charge when the phone's screen was off. After I tried to charge it with another charger, I plugged the original charger back. It worked even when the screen was off.
To be sure there wasn't anything stuck in the portI closed the phone, filled the port with water, waited untill its dry and plugged the charger. I stopped giving me the "Drop" icon and started charging the phone.
After that, I turned on the phone and plugged the charger. The problem was fixed!
But "was" fixed... After a while, the problem still persists.
If you can say what might be causing this, thank you!
I think, the problem cause is Fast Charge 2.0
Now I opened the Advanced Battery Options to disable the fast charging, but it turns out that is was already disabled! But wait, it says that its "Fast Charging". To enable it, I unpluged the USB-C. It enabled itself! After plugging the cable back, the problem is solved. At least for the time being.
Some interesting stuff is going on with this phone XD
I got similar problem. After connecting charger phone says fast charging blablabla and after 5 seconds charging is stopped and then after 1 second it charging again but with no fast charging. I've tyied few diferent chargers and cables also i've cleaned usb c port wiith isopropyl alcohole with no luck. Fast charging missing. Restart and switching on/off fast charging performed few times - no luck. Must be a bug in system... any ideas folks??
well i dont have does issues with my s8... but it did once happen that phone didnt want to fast charge but after repluging the cable issue was solved...i would advice u to take ur device to waranty service cuz solving problems on ur own is not acceptable and ur device shouldnt have those issues.

Can not connect to computer and does not charge(slow charge works only in OFF mode)!

Hi guys,
I've come across a weird issue with my M3 - out of the blue I can not connect to computer via USB cable(the connection is not recognized by M3 and on the PC side it says the connected device can not be recognized). Another issue is that the fast charging is completely gone and even normal slow charging works only when the pad is powered OFF. When its powered ON and put on charger, nothing happens. So I have to power off, connect to charger, it will start charging and then eventually I can power ON and charging will continue. However the charging is very slow and takes almost 6 hours to charge from 0 to full.
My charger and cable are original Huawei ones and are working properly. I tested another huawei charger+cable and same result - no proper charging and no computer connection via USB. My M3 has locked bootloader and never been rooted. I flashed various firmwares(M and N) but no change, problem persists.
Any idea please?
Thanks in advance, brgds

I am having the same problem with my M3. I've tried connecting it to the HiSuite and that isn't connecting either.

I was unable to fix the issue by myself, visited HUAWEI Service Center, they had no idea what is the problem first, then they decided to change the sub-board and returned me the device. Problem was the same so I returned it back to service center, they ordered another sub-board and replaced again, this time everything works fine. Seems like the problem was fixed. BTW my model is US version(wi-fi only) and I am based in SE Asia so I had to pay for the sub-board replacement despite device being under the warranty.

Le Eco Pro 3 suddenly wont charge

So I have been running AICP 13.0 for a couple weeks and love it. I woke up this morning and my phone didn't charge overnight despite being plugged in. It shows it is connected (the lighting bolt in the battery icon on the top right) but the led light doesnt display and it doesnt say charging. Other weird thing is everytime I plug the cord in the volumne starts adjusting itself up and down automatically and now sound is not working (microphone or speaker audio). Battery is now draining and I cant get it to charge. Any ideas why this could be? I have tried it with numerous cords and charging bricks, did a factory reset but still can't get it to work. I am now down to 20 percent battery life and am worried I have a hardware problem and am going to be without a phone for a couple days.
Anyone experience similar things or have ideas to try?
Also leeco doesnt have a us website anymore, so how do I contact them for support if needed?
Only idea a hardreset or clear coch?

Well, go back to any eUI vendor ROM (basically, stock) and see if it solves the issue. Preferably the same firmware version that your device was originally on. It could be a hardware issue or a software issue.
Sounds like a faulty charging port. You might need to replace yours. You can find replacement charging ports on Aliexpress, and a teardown here: http://www.myfixguide.com/manual/leeco-le-pro-3-teardown/ (the phone has the same internals as other LeEco phones, so you can consult various LeEco teardown videos too).
EDIT: now, I don't know if this will work for you, but freezing the phone for an hour might also get it to start charging again, but only do this as a last resort if it dies on you. And make sure you put it in a plastic bag first (obviously).
Ok I will locate the stock rom and flash it, I havent looked for it but it has to be on xda.
As far as replacing the charging port....I bought the phone in June so it should be under warranty correct? Does anyone know how we would get in touch with leeco support? Do we still have a warranty since they shut down operations in the US?
I still have 16 percent battery (I turned it off once I posted here so I could have juice to try ideas you guys would come up with, so hopefully I dont have to try the freezer trick.

Have you tried a different lead? I've had one leeco lead go on me, i almost chucked the charger until i realised it was the lead
Ymm, often the cable is broken.
Yes I have tried numerous cables and chargers. It has to be a hardware issue as it is dead now and won't charge at all is my thinking. When I plug a charging cord in it displays several quick red led blinks where it usually has the yellow led for charging but nothing else. When I tried it with my car charger this morning it got really hot very quickly.

Sadly, the stock charger cable is known to destroy the charge port. If you have always used the stock charger cable, then that is probably what caused the issue . I had to get my phone replaced for that reason about a year ago. If you do end up getting it fixed, get a certified USB-C cable and scrap the one that came with the phone. So sorry man...you shouldn't have to deal with this.
