There's a lot of information about that if you keep a Laptop

Other information I find says it is the charging and discharging
that
wears the battery out.

The laptop i have (with a built in battery) is mainly used in
one
room,
so it is easy to keep it plugged in *all the time* to mains
electricity.

Would it be better to prolong the life of the battery to keep it
plugged in all the time or to go for the 80% - 40% option.
Thanks.

It depends on the charger in the laptop. I have an Acer laptop -
not
the
cheapest they did - which cooks the battery if left in the
machine.
So
I
remove it when not needed. A better designed one wouldn't cause
problems.

Such as the (11 year old) Acer Aspire 3660 I've had on permanent
'charge' for the whole of its life to date which seems to still
have
around 70% or so of its original battery capacity.

Is there much point in having that sort of setup. Surely it would
have
been cheaper and better to have a desktop computer. If it never
moves
or
is never removed from its power.

Depends, a laptop has its own UPS.

and downs in that it can be stolen more easily and
damaged more easily and is usually more expensive
for a lower spec'd computer. I'm not sure people,
buy laptops because they have build-in UPS.
I thought they were bought for protability.

Plenty get them now for the convenience around the house.

Really with a mains lead trailing behind all the time.

Nope, because they dont need a mains lead quite a bit of the time.

There isnt a lot in it at the low end price wise now.

I agree but the screens on the low end range are pretty crap

Clearly those who hardly ever use desktops
anymore and use laptops instead feel otherwise.

but I suppose if it's just used for ordering from
amazon and social media they are OK.

And clearly for everything else they do too.
