My Mi4c only works when charging

[zex006]

After my phone bricked I installed latest Chinese Stable ROM in EDL mode. I chose EDL mode for two reasons (1. I suspected that the phone only works while plugged in to charge and 2. the EDL mode turns off the phone after flashing so I can plug in the charger before booting). Turns out I was right. After the flash was over I tried to boot it without charging it first and it didn't work. After I connected it to the charger it booted normally and the ROM installed successfully.

I tried it again this morning after it fully charged. Few seconds after Ii disconnected it, it turned off. When I tried to turn it back on it was just rebooting to the MI logo screen. I plugged it in the charger and it rebooted 2 times (both times it got to those three dots at the bottom of the screen) and the third time it booted normally.



I also just noticed that the phone is curved a bit (maybe less than 1mm difference between upper left edge and rest of them), maybe from wearing it in tight pockets or something like that.

I think your battery might be dead. Try checking the voltage or the quality.
Replaceable batteries are pretty cheap.

Might be faulty battery, might be bad kernel, might be anything. Best way to check is to try to flash latest dev china rom via fastboot, if it still doesn't work try flashing stable 5.1.1 rom, again, via fastboot. If none of the solutions above doesnt work might be bad battery or worse, the controller on mobo died.

Well I hope it's a battery, because I just bought one to replace it. What is that mobo controller? Is it replaceable?

I have the same issue,
Battery replacement and stock rom of android 7 didn't help
I'm afraid is another hardware issue /:

I do have a similar problem, flashed xiaomi.eu and something have been broken.
I dont know how and why but its very strange.

Unplugged from supply i can boot up the phone, can see the miui logo and boot into fastboot but NOT into recovery and not boot up os.
As soon as i plug in supply it works quit normally, can boot up everything seems to be working, booting into twrp and flashing rom. No problem at all.

If i unplug while running os it imediately shut down.
The battery bar inside twrp show strange jumps.

What happens did somehting break ? Id like to gift the phone my mother for christmas.
