Information

It is quickly discharged in background without cellular connection and Wi-Fi or Bluetooth connection. Battery is worked in less than 1 day, how do I find out which ubtouch service is most active? LineageOS flashed is enough for 2-3 days and more without SIM card, without WiFi and bluetooth.
