I read time by time contradictory advices for the order of microUSB
(referred as uUSB ) charger connecting/disconnecting.

I mean it in context of durability of Android devices
and their uUSB versatile connectors, wrt to transient effects.

Some advices say to connect/disconnect the charger from the grid first,
other advices say to connect/disconnect the uUSB first,
other ones say to connect the microUSB first,
but disconnect charger first.

Connecting charger first / disconnecting uUSB first
may speak for avoiding eventual voltage shocks
due transient states of charger (dis)connecting.

Disconnecting charger first / connecting uUSB first
may speak for avoiding microUSB connector wearing out
due eventual micro sparks, especially at disconnecting.
Some users says uUSB pins can get even burnt by these effects.

As I am not an expert on wearing out factors in electronics,
I would like to hear opinions in context of uUSB charged devices,
eventually in general context of related electronics.
