Battery Life on laptopsWatch
like should you wait until it dies completely every time and then charge it, or should you start charging it at around 10 or 20%?
also can you use your laptop whilst it charging? or is it better to turn it off and let it charge and only use it once its 100% again.
I know people who take their batteries out and just use the power cable when they're gonna be stationary for a long time (days) but I haven't seen any significant advantage in the long run over people who keep their battery in, charge when it's low and keep it plugged in damn near 24/7.
I keep mine plugged in almost 24/7. I only plug it out when I'm moving or when I'm going to sleep and my battery is still good.. ish. My laptop and battery are 3 years old and the battery just started going a few weeks ago. When I just bought it, I could get 4 hours but around the median time I could usually get 2 and 1/2 hours easily and nowadays I get >45 mins.
Maybe plugging in and plugging out according to battery level does have some effect on battery life/longevity but it's probably negligible because all batteries go bad eventually and I'd say 3 years is pretty good.
