This issue is happen after cutting off the power, the RTC battery current consumption is about 200-300mA,

it means the life of coin battery is only 2-3 weeks, it doesn't make sense, but it's a known issue when I search on community...

But our circuit is the same as SABRESD board on PMIC part, it's impossible demo board always exist this issue, so please help us to double confirm it, I think it's not software issue.

Thank you so much

Can you please confirm where you are measuring the RTC battery current consumption, where in the schematic you are opening to measure this current consumption?


Have a great day,
Jose
