#21077 — Order of microUSB charger connecting/disconnecting

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.

My experience is to plug and unplug the same device (S3) from the microUSB
port multiple times a day for 2+ years without issue. I rarely unplug
or turn off the wall wart (or computer connection depending on which
charger I'm using).

I certainly am no expert. But in my case I've never worried about all
that. Most of my chargers stay plugged in for convenience. Never had a
problem. Even had a cheap Target charger fail once and the phone
screen was blinking off and on when I found it. Still no device
damage. IMO it's a big PITA worry about that kind of thing but YMMV.

BTW I've never had a device fail (knocks on wood). It has always
become obsolete first, or I just wanted a new one. Usually within 2
years or so.

Or just "sometimes", which sounds more natural to my ears.

Does not put sometimes less stress on re-occurrence ?

No, not at all.

I certainly wouldn't use "sometimes" to describe something that only 
happened once.

Less stress does not mean exclusion.

No, it doesn't.

Perhaps you are misunderstanding the meaning of "certainly" in my reply?

I do not suppose so, but I may have been confused
by turning to one time events.

As I would use sometimes to describe something that happens only once,
if it was not intention to happen justy once.

there may be opportuunity to happen once, twice, or more times.

but all taht may be fine tuning the meaning and word play,
and I may not get all that correcly as not native.
