<![CDATA[M5Dial RTC battery]]>Does battery connector on the M5Dial supply power to RTC only or it is main power for the whole stuff? I have found that as i connect battery - the screen starts fading out on the usb or main power disconnect which points me to the idea that connector for battery feeding not only RTC but everything. Also the battery is drained very fast and no RTC time survived as it is reset to 0 after several hours

the battery connector powers everything, including RTC. But, yes, when the external battery is fully drained RTC time is lost as there is no built-in battery for the RTC.

You can find the schematics here.

Thanks
