NRF52832 current consumption Issue in connected mode

Connection_mode_with_1sec_Notification.jpg

In my BLE project I am using connected mode, and I found that the current consumption is very high ~190uA during idle mode. I can see small peak at every 30msec. My packet notification Tx happens at every 1 sec. I used below configuration to reduce current but don't see any impact.

Interval Min – 300 msec Interval Max – 320 msec Slave Latency – 4 Supervision timeout - 6

How to reduce the current in connection mode and put device in sleep without losing connection with central?
