I have custom board with nrf 52832. I am using SDK 15.2.0 and softdevice s132 V6.1.0 to transmit advertising packets periodically. I have written simple application that reads battery status and transmitted it in manufacturing data of advertising packet To calculate battery life for custom board I have used advertising interval 20 ms and took readings everyday . I used CR2032 battery for measurement. With this approach I have got battery life 13 days. By doing some mathematical calculation for 1 sec I got battery life 21 months. so I am not sure by this approach I get correct battery life for 1 second. kindly suggest remarks on this. These remarks will be valuable for me.
Thanks in Advance.
