HOW TO TURN OFF NATURAL ANDROID CLICKING SOUND WHEN PHONE LOCK

Settings>Sounds and vibration>Screen lock sounds>Off

HOW TO TURN OFF NOTIFICATION

Long press on notification>Allow notifications>Off

I have tested this on my device, Samsung Galaxy S6 Edge +, for months and it drains 0% battery (does not include system sounds, which is also insignificant). The reason Phonesaber is battery efficient is because it does not require network connection and waking the Wi-Fi radio.

Optimized for battery

Optimized with a low memory mode.

Takes on average 25 MB RAM, with one foreground service. This actually isn't memory expensive, you can manage this under settings->system->developer options->process stats. Peoplestripe and Google Play services are typically more expensive. Phonesaber is run without bind which allows it to be active even when the app is closed.
