Hi everyone,
I just spent the last 2 days investigating the reason why my 9 months old Xiaomi Redmi Note 3 Pro SE was not charging anymore. At first I believed it was due to a faulty charger or cable so I tried many, then I believed it was a faulty battery so I unmounted it and managed to charge it with external battery cells, up to 5%, enough to start the phone and realize it is not a battery problem.
So I turned to the USB and unmounted that one, and then I measured the voltage between the VCC and GND pins while the phone being charged, and here I found only 0.09V where I should have found 5V. So clearly this is a broken usb port, even if I have always handled my phone with great care.
The salty thing is... there is not spare parts to buy for the pro SE version ! So it is totally impossible to find anywhere a new usb dock (reference "H3B_UB"). So after 9 months, I lose all my data and my phone is good for trash. Yeah \o/
This was my first experience with Xiaomi and I recommended it to many relatives before this. Now I'm so disappointed with them.
Any ideas about what to do from now ?
PS: apparently many people have had this problem as you can find several forum threads if you search "H3B_UB" on google
