Battery life: As advertised, roughly around 3-4 hours depending on usage. Probably lasts for about 3-5 days on standby, but expect to lose about 50% charge if you leave it on standby for that long.
Gaming with Shadowgun: Deadzone, it last about 2.5 hours. The same is true with Dead Trigger.
For browsing, it can last around 3 hours and can probably make the 4 hour mark on lower brightness settings.
I initially bought this for PHP 3580 from CD-R King a month ago (around 80 USD), but now it's being sold for PHP 2990 (around 70 USD).
