You have to point the sensor towards your face and look at the screen.
So far feels pretty natural, 70-80% time the phone is unlocked before I think ‘is the phone unlocked’ the rest of the time I forget I need to glance (literally glance with your eyes) at the phone, which I think comes from muscle memory of from unlocking with touchid and not looking at the phone while it unlocks...
Passive security, will become standard across screen based interfaces in the next 5-10yrs...
- dom96 9y agoI'm curious about the battery usage of this. If it's constantly looking for faces, won't this drain the battery significantly?
- gehsty 9y agoBattery usage is good so far, supposed to last 2hrs longer than the iPhone 7/8. It periodically scans for attention, not battery intensive, and can actually be battery positive as it aggressively dims the screen and then turns it off if it finds it is not being looked at.
- amazingman 9y agoIf iFixit’s characterization is correct, then the authentication process happens in stages, each of which is more energy expensive (and likely uses different hardware) than the previous stage. If true, then it stands to reason that there is at least a conceptual path to minimizing overall energy budget.
