In regions with fluctuating cellular coverage, such as the mountainous terrain around Geghard or Dilijan, your device may indeed expend more power searching for a stable network. To optimize battery performance with CoreESIM, consider manually selecting your carrier in your device's cellular settings. Locking onto a strong, consistent network, such as Viva-MTS or Ucom, can prevent your device from constantly scanning for alternative base stations, thereby reducing power consumption.
