As I’ve noted briefly in my TechEd 2010 coverage, Windows Phone 7 have come a long way in terms of responsiveness and performance. Perhaps a good benchmark of the improvements they’ve made to the operating system since MIX10 and certainly its debut at Mobile World Congress is the start up time.
The short video above features a prototype LG Windows Phone 7 device with a recent but still not final build of the OS doing a cold boot after removing and replacing the battery. Consistent across several tests, the device booted in an impressive 30 seconds. What’s remarkable is that as soon as the lock screen displays, it’s fully initialized and ready to be used.
Smartphones are not known for the fast boots and the fastest Windows Mobile 6.5 device on the market today, the HTC HD2, takes easily a minute to boot and at least a further 15 seconds before you dare to touch it. Earlier builds of WP7 at MWC took at least a minute to boot too. Considering this is still a work in progress, I’m optimistic they’ll improve it even further.
