According to my research, batteries have charging cycles. So the more I drain and charge it, the faster it will die, right? I don't know, the research was mainly about smartphone batteries. So...
My old laptop's battery died in 2 years and I was using it the casual way. When it alerts me the battery is low, I plug it in. When it reaches 100%, I plug it off. So, it took 2 years to die - probably, in my view, due to higher numbers of charging cycles.
My current laptop is 5 years old now. It recently died so it took 5 years for it. And this time I just kept it plugged in as long as possible when the computer was on. Unless there was no electricity, or I had to move the laptop, it was always plugged in at 100%. I'm using the laptop kind of like a desktop. Always on a coffee table or on a desk. So the cables don't really bother me. But please don't say "Then why not use a desktop?" because I constantly have to move between different cities due to studying collage in a different city.
(BTW, when I say the battery died, I mean without the charger the laptop wouldn't even open)
So... Can we conclude from this that we should keep the chargers plugged in when the laptop is on? Or are there any downsides of this? (Which I haven't experienced - or did experience, but didn't know that it was caused by keeping it plugged in)
