I tried Standby Mode using Arduino RTCZero library. I have also removed the Power LED and supplies 3.3V directly at 3.3V pin (by passing LDO). I’m getting current in range of 300uA.
Considering ATsamD21 can go down to 10uA this is too much current drawn!!
Not sure if its due to Hardware of Sparkfun board or the Arduino RTCZero Library
I tried Standby Mode using this RTCZero library.

I'm getting current in range of 300uA which is Okayish.. considering ATsamD21 can go down to 10uA. Can someone suggest what else I can try?
No public wish lists :(
