There are a few threads saying The AGXi’s RTC consumes ~400uA, but AGX only ~2uA? Is this true? Why it is not in official datasheets or other document?
Why none-rechargeable lithium battery, like CR2032, are not listed in the supported battery type in the datasheets? Can we use this type? Do we need to turn off the PMIC charging circuit? How?
As said in the data sheet, the following backup cells may be used, so the non-rechargeable battery is ok too:
Super Capacitor (gold cap, double layer electrolytic)
Standard capacitors (tantalum)
Rechargeable Lithium Manganese cells
