What are the consequences of using a laptop permanently connected to the network?

Question

Batteries

If you use a laptop fully charged with the charger connected (when you are at home and there is no need to use the battery) - will this ultimately reduce the battery life or battery life? Now I use it according to the principle: I discharged up to 15-20%, put it on charge up to 100 percent (99) and after charging I turn it off .. Or am I more likely to kill the battery with constant discharges?

Answer 1

I've been keeping my laptop constantly on charge for 3 years. Capacity has dropped by 4-6% according to the software. In reality, probably more, about 20%, because. This is a feature of lithium batteries - aging.
Your capacity will decrease faster from aging than from charge-discharge cycles or due to a constant charge of 100%.
At the expense of the optimal 40-60% charge - then you need to store the battery at about zero temperature, otherwise the effect is minimal.
Basically, don't worry about this.

Answer 2

there is no difference, do not read this nonsense, they say the battery will die, etc., since now there is a charge controller on all laptops without exception

Answer 3

On the old Sonya (2011), the battery died pretty quickly, less than 2 years. I can’t say the exact reasons, but exactly the same one, which was not constantly on charge, is alive and cheerful. Now I keep Lenova in the "do not keep more than a day with a charged battery" mode (naturally, I'm not ready to constantly monitor the charge level, so I don't go down to a manic disconnect from the network). The option to charge up to N% is also not suitable, because I don’t want to suddenly end up with a half-charged battery. So far, the flight is normal.
