    Hi,
    I have mi Mi2a since 6 month, i take very good care of it, but since 4 weeks, I have connexion problem on my micro usb charge port. I need toput the cable and the phone in a certain way that the cable weight down when the phone repose on his back.

    This night it became a worse as the phone discharge totally because of cycling through charging/not charging (false contact with usb cable) and i had to shut it down
    i am not sure though if the problem come from the micro usb plug itself or the soldering on the board. i was looking for a kind of repair manual or instruction or exploded view to know wich part i have to replace and where to find it.

    I am not afraid to do repair as repairing phone is my job, but i prefer to gather information first, even i know it'll put it OOW.

    Thanks for your help

    Simply dust or dirt inside the housing maybe? Take a vacuum to it, that helped me before. Or maybe a small q-tip swab.

    I tried this already. I'm pretty sure not for me it seems a false contact in the micro usb plug. Anyway the phone almost don't take charge anymore... i had to buy new one. I'll check later

    Oh my. I have been facing the exact same problem for the past week. There is no dust built in the port and I need to weigh it down to charge it. I used scotch tape to press the connector down and charge it fully. I am figuring out a way to fix it. :(

    That's how I was able to charge my phone now. Bought the phone in May. Problem with the whole lot? Problems become worst. Yes. My bet is that the solder is bad/cracked for the USB port on the board. Hence unable to charge normally.

    That's my bet too. I could do it recently by blocking the charging phone between two wood panes of a chair

    Use scotch tape to press the usb down onto the connector. Scotch tape leaves no glue residue. Need to find a fix for this soon. I emailed ******* support.

    Not until i'll repair it. I'll keep it for spare phone in case (don't wanna fall back to a nokia in case i Have a problem with my primary phone). I was planning to buy a mi3 anywzy, too bad i couldn't wait it was out, but i hope miui will get his way on the LG G2 Soon enough. For now mihome saved my day

    I found a fix online after some searching. But you need a replacement part - Micro USB Flex cable. Its a small circuit board with the connector. I asked ******* and they said they don't have it. Or this is available on ebay:

    That's a replacement micro-USB port. Need to desolder the existing and solder this and my guess it would work.

    I agree. I am searching for the flex cable too. Soldering is a pain for such tiny stuff.

    So I was able to solder a new Micro-USB port on the phone. Unfortunately that didn't fix the issue. The whole module needs replacement. Not just the micro-usb port. Tough luck finding that.

    The part is hard to get. I will also get in touch directly with Xiaomi.

    That part I am sure is bad on daughters phone, also. Replaced USB port, didn't fix. Ended up with spare battery and external charger to keep hers working'

    So many cases,it looks this phone should not be left on night charging.
