Hi,
could you please share how charging LED / Error LED will behave in various conditions. I could not find this information anywhere.

I am talking about how blinking will happen when it will be OFF when it will be ON?

The CHG LED is active only when the battery is being charged and the ERR LED is active if there's an error condition. None of these are blinking. You can connect these signals to the host MCU, hence blinking will just make things difficult.
After the charging of the battery is completed the charging LED is blinking on my npm1100 evaluation board. See this video.

It should not do that. Can you try another battery? What it is the battery voltage when the LED is on and off?
Battery is a new Phone battery and it gives good backup.
When LED is ON the voltage is 4.221V and when LED is off the voltage is 4.167V
Vterm is set for 4.2V
Can you provide a scope plot of VBUS, VSYS and VBAT please?
