Message Says "Your Device is in Power Saving Mode and the Network Connection is Sleeping"

 Symptoms

• Notification message "Your device is in power saving mode and the network connection is sleeping"
• Results in being unable to receive calls or texts while the phone is idle

Environment

• Alcatel A30
• Motorola 3.0 phones
• Google and Nexus 3.0 phones
• Samsung 3.0 phones
• Android 6.0 Marshmallow and higher
• Republic Wireless app version 3.18.0.80 and higher

Resolution

One possible solution is to add the Republic Wireless app to the list of apps exempt from Android Doze mode:

• How to Change the Battery Optimization Settings on Alcatel, Google, Motorola, and Nexus 3.0 Phones
• How to Change Battery Optimization Settings on Samsung Galaxy Phones Running Android Nougat

Cause

This message is the Republic Wireless app reporting that Android has entered into Doze mode, and has put the network connection to sleep. When you wake up your phone from Doze mode, or if there is an incoming call, the Republic Wireless app will then say "Connected to WiFi" or "Connected to cell".
