The Ultrabook versions of Haswell, the 4th Gen Core from Intel, bring something special. Connected Standby is the mark of an Ultrabook that’s been built to very tight power efficiency standards, brings alive a part of Windows 8 that few have considered before and gives you the best-in-class in terms of battery life. The Sony Vaio Duo 13 has been built to this standard and although the re-branded Sony Active Sleep was rumored to be a feature that would be brought alive with Windows 8.1, I have it working here on a Windows 8 sample sent to us by Sony. Demo below.
I haven’t been able to test CS power usage yet due to time constraints but I’m expecting a local MP3 playback battery life of at least a few days and up to a week if the advantages are the same as it is on Clovertrail Windows 8 devices.
There are a couple of things to note about CS-approved devices. Due to the tight requirements there’s going to be a limited selection of component options for systems built to CS standards. LPDDR3 RAM and a WiFi chipset from Broadcom (WiDi capable) will be the same on many of the first wave of devices and it’s likely that the (required) SSD is soldered on board but we’ll test those components for you in a full review.
Apart from that, the Sony Vaio Duo 13 is turning out to be a lot more usable than the Duo 11 which was great but lacked quite a bit on the productive side of keyboard input. With a bigger digitizer screen and a better keyboard along with the huge battery life advantage, the Duo 13 has a lot going for it. Full review from us soon.
