It’s not a very intensive test (no tasks are performed) and doesn’t reflect the way real people use computers. However, this score establishes an baseline for low-intensity usage. Those who are writing documents or emails can expect a new Satellite U845W to last about 6 hours.
1080p video (3:15) The HP Envy 4 can play a 1080p MP4 video (50% brightness, WiFi on) for three hours and fifteen minutes, which is about a movie and a half. It’s also important to note that this test used a 1080p video (1920×1080 resolution), which simultaneously under and over-utilized the screen. There were extra vertical pixels that the screen didn’t have the resolution for, and there were black bars on the side from the unused horizontal resolution. Regardless, the Satellite’s battery life is completly usable, but nothing really special.
At the $1,000 MSRP, the Satellite U845W loses out on value to several other computers with similar components that are currently retailing for significantly less. Even if it were on deep discount, the flaws with the form factor and the trackpad mean it’s not a value at any (reasonable) price.
A lot of the extra horizontal space on the side of the keyboard is dedicated to harman/kardon-branded speaker grills. I took a listen though the best of Top 40 (so basically I listened to Young Money and Kayne West), and while the bass was boomier than my normal daily driver, the MacBook Air, that’s not saying much. It was a marginally better experience than other laptops, but it’s still not a feature worth paying extra for. The exact person who would pay more for a laptop with better speakers probably isn’t listening to laptop speakers anyway.
