Seeing batteries ranging from 50Wh to 86Wh on similar-sized gaming laptops. Manufacturers always quote some unrealistic 'up to X hours' number. What do people actually get on battery with a dGPU laptop during normal non-gaming use?
On a 56Wh battery laptop with a dGPU I get maybe 4-5 hours doing just docs/browsing with the dGPU disabled via Optimus. Turn on the dedicated GPU for anything and that drops fast.
