Redmi 4x doesn't show charge speed on lock screen

Xiaomi Redmi 4x doesn’t show charge speed on lock screen

You need to wait for a while, system takes a few minutes to ten minutes to estimate the remaining charge time.
But…
Because system doesnt support real-time detection of charge current on some devices, it cannot show charge speed.

Aida64 shows charge voltage well

The application can detect the charge voltage and current, doesnt mean that the system can detect the charge current by its own program logic (logic for show charge current on lock screen, add by MoKee team).

It works on other firmwares, for example aex, rr.

Their developers are different, some features may not be added.
