(STC3115) Effect of battery discharge on OCV measurement

How much error will occur in the SOC calculation results if discharge occurs during the initial OCV measurement?
Also, is the OCV measurement timing other than the initial stage of charging? At that time, are you looking at the battery current and measuring it when it is 0A?

Application specifications
A lithium-ion battery or USB output is used as an input on the application side.
The input power on the application side must be uninterruptible.
Therefore, the “RSTIO” pin of STC3115 cannot be used.

Battery specifications
Battery: Lithium ion battery (3.7V)
Capacity: 4000mAh
Charging: CC800mA, CV4.1V
Discharge current: 360mA

Gauge IC settings
Current sense resistor: Yes. 47mΩ
Charge Inhibit function: Yes. Connect BATD/CDpin to EN of charging IC
