Hello all,
Does the nPM1300 fuel gauge consider battery degradation over time?
I checked the battery profiling guidelines or other related fuel gauge pages within the Infocenter, but could not find a distinct answer.
Best regards,

FYI (and for information for anyone else working with the device), it appears that the update rate is indeed important, at least while providing SoC estimates during discharging.
In testing in my application with a constant (500mA) current draw, I've seen significant differences with an update rate of 1 second vs. 30 seconds. With the faster update rate, the estimate is more accurate, as expected. At a 30s update rate, the estimate was not accurate enough for our application (e.g., SoC estimate was 60% vs. 30%, when 30% was closer to accurate). I'd love to know if there were best practices for update rates vs. states.
Also, FWIW, in informal testing, the algorithm does not appear quite as sensitive when running charging calculations
