Help Mi phone doesn't start/charge after full discharge unless I use original cable

[coldpumpkin]

Howdy,

First of all I bought my first Xiaomi phone last week, a Mi 10T Lite, currently with MIUI 12.0.2.

Today the phone got fully discharged so I connected the charger. I'm using the original charger socket but with another/non-original cable (5A, purple colour on sockets) because it's longer. I left it for around 30 minutes like that and I couldn't ever turn it on. The LCD displayed a battery icon with a bolt symbol in it.

I swapped the cable for the original one (orange colour on sockets) and instead of a bolt symbol, it displayed 2% and I managed to turn it on.

After it was on, I swapped the cables again and it's charging normally.

What the heck?

TLDR: Phone doesn't charge if using a cable other than the original one but only when it's fully discharged. After turning the phone on, it charges just fine.

you can try a factory reset and see if it was just a software bug. if it still does this, then it might be a hardware issue....most likely your battery would be my guess.

First, try to never run the battery completely dead.
It is good practice to not do that.

Second, regardless of quality, there will be voltage drop when you use a longer cord, so the device will charge slower- sometimes so much so that if you are using the device it cannot keep up with battery use.
