[Q] Google Now and always listening

[joelteixeira]

Dear all,


I would like to hear from you about Google Now shortcut and "always listening" feature like we find on Moto X. I'm tempted about Moto X price/specs but I'm kind of disapointed about his camera and would like to know if is there a way to use those features (always listening with google now) on xperia z3.

Is there any chance to get this on xperia z3?

My Z1 listening to me a the time while screen is on.
And it's listening 24/7 at charger.
So basically, only conditions that my phone doesn't listen is when is off the charger and screen is off.

Thank you. So, as long the screen is on, you can say "OK Google" in any screen to activate Google now? It's incredible how this neat feature seems to be exclusive to Moto x (working with screen off).

Yes, while screen is on, or on charger (then its same if it is on or off).

Its exclusive because of hardware, Moto X have low power consumption third microphone, and low power consumption CPU that handle this "Always listening" while other manufactures dont have this kind of "hardware" inside of phone which would lead to heavy battery drain.
Just imagine keeping heavy snapdragon 801 always on just because of one microphone?

That's the part I don't understand, as far as I know they have the same SoC. ?

Yes, but Moto X have second CPU, dedicated just for listening onto third microphone for "ok google"..
For example.

When Moto X is sreen off, main CPU (snapdragon 801 is in deep sleep), while second one (dedicated for listening) is working.
This second one is power efficient, and dosent drain battery so much.

Examlpe for xperia.
Since xperia dosent have "second cpu" it would look like this.
When Xperia is screen off, main CPU (snapdragon 801) is not in deep sleep, because it must listen for your "ok google" command.
Which means more battery drain because 801 is not designed for things like this.

Also this "second" cpu is few mhz strong on moto x.
