Does it make a difference whether I have my notebook plugged in all the time or only plug it in when the battery is empty?
I mean, when the battery is at 100% and you are connected to the power, it doesn't do anything other than stay at 100. You can't go beyond 100%. In so far it is theoretically the same as if I let the battery run empty and then upload it up to 100. Or how do you see that?
I prefer to have it on the network, because the display is better then, and you can save the battery. Completely discharged is not good for the battery. The best is a 15% -85% charge.
How do you mean the battery charge? You can't set it to always be between 15 and 85%.
If you keep your laptop plugged in and the battery is already full, the laptop is using the power adapter to provide power and trying to keep the battery charged. However, the power supply only needs as much as the laptop actually consumes (+ 5-25% conversion losses).
No, you have to take care of that yourself, by pulling out accordingly, but the laptop's battery will last longer, which is also the case with cell phones and tablets. Yes, I never do it either, but the battery will get weaker over time if you always discharge it completely.
So it only costs a little more if you have it connected all the time?
, Yes.
The aforementioned conversion losses also occur during normal loading.
It doesn't stay at 100% by itself. The energy to stay at the level has to come from somewhere.
In addition, the power supply unit draws a current from the socket even if it is not connected to the notebook, albeit a small one. The provision of energy costs energy.
