I had a full size laptop, complete with some sort of fancy graphics mumbo jumbo, and a DVD drive, so on and so forth. That battery life was about 45 minutes. I have yet to reach a low battery warning on this device, with 10 hours use. Mind you, I am not a gamer. I use the internet and occasionally stream movies or shows.There are a couple annoying features, but they're easy to get used to. Namely, the letters on the keyboard are lower-case, the keyboard doesn't have a "Delete" button, and where the "Caps Lock" button usually is there is a "Search" button, which accidentally gets pressed on occasion.Other than those things, the device is perfect, and I look forward to using it for a long time.
