Brand new Razer Blade Pro 2020 17 *broken or design flaw

Brand new Razer Blade Pro 2020 17 *broken or design flaw? The laptop has serious performance issues as soon as you uplug from the mains power, the drop in performance is signficant around 40% of advertised specs. If you can only have 100% performance plugged in, this is not a laptop but really should be called a desktop PC as you have to have it plugged in for advertised specs? A laptop is a portable device if it has to be plugged in how is it a laptop. This is my first razer laptop and im seriously upset considering how much i have spent here. I have bought a very expensive lemon... No where on your product page for the new razer blade pro 2020 model, does it state loss of performance expected if on battery power. No where at all. Benchmarks mains vs battery: Timespy 8295 vs 3613 Firestrike 18739 vs 8285 3dmark11 23583 vs 11824 3dmark06 43235 vs 29410 This is clearly subject to this laptop being designed with a sub par battery if power throttles underload. 40% of performance or less is not acceptable on battery.
