i'm convinced windows laptops have negative battery capacity. in all my years of being exposed to tons of different windows laptops, i've yet to have a single one that holds a charge for more than a few hours. not a single one could last a day of use. i've used chromebooks that have lasted me weeks on a single charge. the only place i'm using windows is on a desktop so i don't have the thing die on me after having affinity designer open for more than 5 minutes.
