Modern laptop battery performance when always plugged in

[bsoltan]

Hi all,

I'm considering replacing a desktop I currently have twith a laptop that can be plugged in to two external monitors most of the time but also offer portability without having to sync everything to different machines.
edit: Oops I should mention this isn't a laptop for gaming, it'll be non-gaming when docked and very light gaming if I'm away.

Several years ago I seem to remember it was a bad idea to keep a laptop constantly on power as it degraded the battery.
Do I still need to worry about this, or are modern batteries better these days, I understand mobile phone battery technology improved on this.

Is there anything in particular to check in laptop specs for this? I'm considering a high spec machine (Dell XPS/Razer Blade/Macbook etc.)

Thanks

I bought a Dell back in 2007 and kept it plugged to the mains 24/7. It lasted until 2016 before the GPU fan failed and the laptop wouldn’t start up. But in all that time, the battery worked perfectly in the occasions when I went without power.

Thanks! So maybe it is just something I've made up in my head? For me older laptops the battery life always seemed to be the thing that went first. They would start with 4-5hours but after a few years only get 30mins or so.
