Temperature calibration should have already been done in the underlaying twl4030 iio driver. Discharge rate is the real current flow reported in uA. Also reported by iio. Ack, but there's rather severe temperature dependency of the lithium battery, which you should take into account if

Hi! to introduce coefficients for temperature and discharge rate? What do you mean? Nothing like that is used in current driver why do we need to add it? Well, conversion between Li-ion's voltage and state of charge at 0 current is well known: We can’t measure at 0 current since
