My Dell Inspiron has this default and maximum feature of having a dimmed LCD setup. I think it’s a good configuration, battery-life wise.

I don’t think either statement is true, neither of those would happen, if the battery fries, then you’re guaranteed a new one. As long as you have at least 75% battery it’ll work fine. If you’re planning to go a long distance with it, leave it charging.
