Hey everyone,
My laptop is around 2 months old. I don’t really bring my laptop outside so its always charging. (Battery plugged into laptop). I’m just wondering, is this a VERY easy way to kill the battery, making me having to replace a new one? Or do I have to, charge it until its full, use it, then charge again and repeat?

Note: My Laptop battery only lasts like 2 hour on full brightness.
Putting it in low brightness hurts my eye.
