Hello vinay singh,
>1.) How to avoid deletion of bonded remote device (mobile) after power cycle of device ? (We are using Thunderboard EFR32BG22)
The bond information is stored automatically in the NVM when a bond is created. Make sure you don't delete the bondings in the boot event and your bonding information should be kept after a power cycle of the EFR32 device.

Check our documentation and guides in doc.silabs.com.
More specifically for sending a notification, you can check the:
Hello Jesus Grillet,
Thank you for your response !
I Followed the below link and created pairing process events for autoconnection and saving bonding with remote device :-
1.) In our mobile Bluetooth settings it only shows the device is paired but doesn't show it is connected for most of the GATT Profiles.
But for HID Over GATT Profile i am able to see connected in mobile Bluetooth settings.
2.) Once mobile Bluetooth is off the connection gets closed for most of the GATT profiles (I confirmed by debug print in event "sl_bt_evt_connection_closed_id").
3.) When mobile Bluetooth is turned on it doesn't open the connection again (simple word "autoconnection").
But in Case of HID over GATT Profile the EFR device gets autoconnected .
1.) Why only for HID Over Gatt profile I can observe connected in mobile Bluetooth settings ?
2.) Why autoconnection is only working in HID Over Gatt profile ? (not for any other Gatt profile)
Please refer any link or document to achieve above scenarios without the dependency of HID Over GATT profile.
Thank You !
