Smart wake up

What is smart wake up?

Smart wake up looks for the best moment to wake you up. It utilizes sleep tracking to determine in which sleep phase you are at the moment.

Waking up in light sleep feels natural and can be compared to waking up on the weekend, without any alarm.
In contrast, deep sleep wakeup (which is common with ordinary alarm clocks) leads to an unpleasant wakeup experience accompanied with feeling of being tired, sleepy, disoriented etc.

In smart wake up, you set up not only one time for the alarm, but a window (also smart wake up period), in which you’d like to be woken up once it is the right moment.

EXAMPLE: with a smart wake up period of 30 minutes and alarm time scheduled for 8:00, Sleep as Android will wake you between 7:30-8:00, once you are in light sleep for some time. The scheduled alarm time (8:00) is considered as the last possible wake up time to manage your daily duties such as arriving at work on time etc. 

How to set up smart wake up?

Smart wakeup has a default setting (for newly created alarms) and a per-alarm setting (so you can set each alarm differently).

TIP: You can use a longer smart period for weekends and shorter period for workdays.

Configure the defaults in Settings > Sleep tracking > Smart wake up.

Power Nap

Power nap is a special case of smart wake up for situations when you don’t have an maximum time when you need to be woken up, but you prefer sleep a given time for sure and then finish one whole sleep cycle afterward. Let say it is weekend and you can wake up any time after 10:00. You will schedule a power nap alarm for 10:00 which will look for the best moment to wake you up between 10:00-11:00. Or similarly you can do a nap of minimum 20 minutes but keep Sleep as Android find you best moment afterward so power nap will make sure you sleep at least 20 minutes and find the best moment in 20+1 hour.
