I bought my first laptop five days ago. Since I don't have any prior experience in maintaining laptops, I don't exactly know how long my 41 WHr battery should last after a single charge. I was constantly using my lapytop between 85 to 35 percent of charge for the past days. I get about 3 hours and 10 minutes with that charge. That means I can get arouund 6 hours runtime with 100% charge.  Is this the normal battery life of laptops in this range?
