Ya, the laptop you're talking about does support Nvidia Optimus technology. It's a technology provided by Nvidia and it is up to the laptop manufacturers to implement it. Your laptop does have the technology implemented.

Buddy, the question is itself wrong. It entirely depends upon your usage. If you use only GPU intensive works like playing games or watching HD movies for a long time, then only the dedicated GPU will be used resulting lower battery life.

Normally for average usage, it can provide you 30 mins to 1 Hrs of extra battery life in ideal conditions.
