Beacons - Battery usage too high when scanning beacons


Is anybody had any issues with the % of battery usage when scanning beacons? We have noticed that our mobile app is not consuming a high % of the phone battery when only scanning for beacons, but as soon as it detects one (either using BLE Plugging or the Beacons plugin) the battery usage % increases lot. 

Any advice here? 

Thank you!
