Purchased this item on Amazon since it had a good pricing compared to other outlets. Ordered this beefed up i9 model since I thought I would use it for long time so why not spend extra few hundred bucks more than base model. Turns out this i9 processor is very powerful and consumes a lot of energy. Since I do not work on anything that requires that much processing power I've decided to return this in favor of a base model which is cheaper and i7 therefore uses less energy. I could literally notice that battery percentage was ticking down which rarely happens on a new and expensive laptop.
