Sony Touts 25 Hour Battery Life For Haswell-Equipped Vaio Pro

An anonymous reader writes "Sony claims that both the new 11.6-inch and 13.3-inch models of its Haswell-equipped Vaio Pro ultrabooks are the world's lightest. The 11.6-inch model weighs in at 1.9lb (0.87k , where as the 13.3-incher is a little heavier at just 2.33lb (1.06kg). But it's the battery life on offer here that really makes the new Pros stand out. The 11.6-inch Vaio Pro offers 11 hours of battery life as standard, while the 13.3-inch achieves 8 hours. However, Sony is also offering a sheet battery you can connect to the base of the ultrabooks. On the 13.3-inch Pro that increases battery life to 18 hours, but on the 11.6-inch you get a true day-long amount of juice with 25 hours of battery life claimed."

Waiting for Apple

Let's see what Apple can get away with in their next MacBook refresh...

Say what you want about Apple, one thing you cannot (rationally) debate

The only reason you cannot rationally debate that is because Mac fans are so irrational.

I've never seen a Mac get within 2 hours of it's advertised battery life, you'd be lucky to get within 3 hours of it under normal usage. Iphones/Ipads are even worse for advertised battery life vs reality.

Yet I fully expect rabid Mac fanboys flame me for saying this. Ad Hominiem is the first thing I expect.

Much like advertised fuel economy, advertised battery life is a huge lie. It's done in controlled conditions and deliberately disables or hobbles things people want to use (I.E. screen brigtness). The advertised fuel economy depends on you spending x minutes at highway speeds, less than y minutes idling and always accelerating at the vehicles optimum rate, conditions that can never be replicated in the real world, battery life is the same. They assume you will not use the optical drive, you will perform less than x writes to the disk, you will use the screen at 25/30/40% brightness, you will never use more than y% of the CPU, the video codecs used will be the most efficient etc... again conditions that can never be replicated in the real world. All manufacturers do this, from Toyota to Toshiba.

Advertised battery life is an exercise in lying by marketing and if I have to praise Apple, it's that they are excellent at marketing, I'll even say they are unmatched in that field.
