Thingy52 battery reads are not consistent

[Gotta]

Seems battery reads are not consistent in thngy52 2.1.0 software. Observed a ~4% difference in the consequent battery reads. This difference is high (upto ~40%) if the thingy is connected to USB charger. Is it expected? Br, Ggotta

Thanks for the detailed explanation. "When you say the difference is high if the Thingy is connected to a USB charger, do you mean the difference between the state of charge (%) before & after you connect the USB charger? Could you post a graph of this occurrence too please? " In this case, it is not at the time we connect charger, it is observed over a period of time. Noticed 89% of battery percentage after connecting the wall charger, before it was 32%. And from that instance the % values were sometimes 32-36% and sometimes it was ~89%. I observer for couple of minutes and then moved onto some other task. I didn't capture any graphs or logs for this.

I have talked to an expert here at Nordic and he believes it should not be too difficult to filter out more noise to get more stable state of charge values when the Thingy is discharging (i.e. not charging via the usb cable). It seems slightly weird that the state of charge would vary that much while you are charging the Thingy. Might be some inaccurate voltage measurements during the charging phase that leads to the big discrepancy that you describe. I will talk to our Thingy:52 experts & get back to you.
