Android BLE ScanCallback LOW LATENCY

I'm building BLE Android. My app scans BLE devices with a background service 24/7 (this is important for my app) with SCAN_MODE_LOW_POWER parameters as settings. When I find devices associated with my app, I switch to SCAN_MODE_LOW_LATENCY, because at that moment my app is counting every 1 second. With SCAN_MODE_LOW_LATENCY I am getting ScanCallback intensively, but at some point, for example when the device is in sleep mode im taking as 10-11 a callback intensively, then pause for 3-4 seconds and then callbacks again.

This 3-4s delay / pause is not helping my application.

Is it possible to have an intense ScanCallback even if the device is in sleep or dose?

Thank.
