Ok,thank you.I think I will use this method of SAADC to measure.

Hello,

The options here will depend on your HW and the type of battery you use. For example, if you have a primary cell battery connected directly to VDD, you can use the built in SAADC to sample the input voltage and estimate the state of charge based on the discharge curve for that battery. We also have PMICs such as the npm1300 (https://www.nordicsemi.com/Products/nPM1300 ) with battery fuel gauging support.
