Can I leave my MacBook plugged in overnight?

Question

macOS

Is it harmful to leave the MacBook Pro 2013 retina on a charger overnight? It charges in 3 hours, and at night - 8 hours approximately. Is there any problem with this? Does the battery lose capacity, are some elements not loaded?
Same question for iPhone 5.

Absolutely nothing will change.

However, the author forgot to take into account that there is a fuse, and it is present. So he will work the stated hours so what so.

Answer 2

No, it's not harmful. In the included mode - even it is useful.
In poppies, as soon as the battery is fully charged, it uses direct charge to work. If the charge is not used, charging stops. I don’t know how it works deeper, maybe someone here will explain.
Also, from a poppy with charging turned on in the closed state, you can charge via USB, which, as it were, hints;)

Answer 3

In our office, 80 people have MacBooks. And no one ever turns them off. Half of the MacBooks work 24x7, the rest simply go to sleep or block the screen before leaving.
For 3 years, there were practically no breakdowns. Basically "Poured tea" or "Dropped".
So don't worry, he won't get worse - for sure

Answer 4

Macbooks have a tricky charge controller that prevents the battery from degrading from a constant charge current, turning it off when the cans are full and turning it back on when the charge drops to 90-95%. That is why ordinary PC laptops drain the battery after a year, and keep poppies for four years within the tolerance for natural degradation.
Leaving the poppy on charge is not at all harmful to either the battery or the internal components. In engineering terms, its power distribution system is two heads taller than most PC laptops.

Answer 5

the battery always loses its capacity, even if you charge it or not, you can’t get away from it

Answer 6

You can at home. On the street, no.
