Default [Q] Power Saving Mode?

I just got the M7 yesterday and updated to sense 6 today.
The only problem I see with this phone is that the battery is draining too fast.
So I'm trying to find the power saving mode.
I looked up at the manual and also some videos and found out that sense 5.5 has power saving notification
but no mention about sense 6.
So my question is that where can I get the saving mode in 4.4.2 sense 6?
