Is it better to use laptop on battery or on AC power?
I recently bought a new Samsung R480. It's capable of handling games pretty fairly cause of the nVidia GeForce 330m discrete graphics card. The problem is that it can only last on battery for approximately 2 hours. My question is whether or not it's okay to leave the battery in while I use it with the adapter plugged in.
The difference of my question with other questions very similar to this is that Samsung has a feature that lets the laptop charge only until 80% supposedly prolonging battery life. Also, when I check the battery icon on the taskbar, it says that it's not charging, which i assume to mean that it's not wasting cycles.
