This is true battery saving. No Placebo and Silly Marketing Pranks!
Naptime reduces your device’s power consumption while the screen is off by leveraging Android’s built-in power saving functionality. Faster inactivity means less energy is consumed unnecessarily. By default, doze can take a while to activate, so Naptime simply speeds up that process automatically for you.

Supported Android
(4.1 and up)
Nougat (7.0 – 7.1.1),Oreo (8.0-8.1), Pie(9.0)
