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

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.

But they still keep them topped up in case they do,

All they need to do is charge it in the one place and use
it without being plugged into the mains everywhere else.

Yes same goes for tablets and smartphones.

And that is why hardly anyone uses desktops anymore in the
home and they use laptops, tablets and smartphones instead.

Thats what I do with mine, its on the charger
all the time its in the fixed place in the kitchen
and isnt when I use it everywhere else.

Same as my ipad then and my ipod(s)
On the floor under the table.

That is much better than with a desktop system
which isnt as portable and which has to be plugged
into the mains whenever you do want to use it.

my retina imac has always been used on teh same table in the same place

And most prefer the extra flexibility you get with laptops and tablets.

I like a 27" screen and as yet NO laptop comes with a 27" screen.

Most clearly dont care given that hardly
anyone has a desktop at home anymore.

I;'ve used a laptop with a 17" screen.
I have a 15 & 17 inch screens in my loft that I donlt use.

and they rarely do

Rarely do what ? Most dont use their laptop in just
the one place even if it hardly ever leaves the house.

hence the original question.

The original question is about something quite different,
whether to leave it charging all the time when its in the
place where it is charged.

Why leave it on charge ALL THE TIME ?

That way its fully charged whenever I need to use it anywhere else.

they use tablets and snartphones.

Plenty dont use them as much as their laptop.

I dont use my table anything like as much as the laptop
and I dont do what I do on my laptop on my smartphone.

I prefer my desktop fopr most things.

Clearly most dont anymore.

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.

So why do people buy tablets and desktops ?

Hardly anyone buys desktops anymore.


Tablets are much more portable than laptops
but arent as good when you have to enter more
than trivial amounts of data.

Few peole need to enter that much data nowadays.

Plenty still do with facebook etc.
