- Navigate to "Settings --> Device maintenance --> Battery --> Advanced settings" and turn off "App power monitor"
- Navigate to "Settings --> Device maintenance --> Battery --> Battery usage --> Optimise battery usage", select "All apps" in the drop-down menu and set the switch next to "PassWallet" to "off"
- Navigate to "Settings --> Connections --> Wi-Fi --> Advanced" and set "Keep Wi-Fi on during sleep" to "always"
- Navigate to "Settings --> Apps --> PassWallet --> Mobile data" and enable "Allow background data usage"
