RTC for Colibri iMX6 Dual

Dear Srs.,

I’m using a Colibri iMX6DL and I developed my own Carrier Board.

I need a RTC for my application. I used the same circuit at the Colibri Evaluation Board document.

Attached, a picture of my circuit.

Diodes D13 and D15 are B160.

My problem is that the battery discharges very quickly.

In 30 days of use, it already has 1V.

Any suggestions for my circuit - or just adding an external RTC to solve this?

hi @dlmmartins

As suggested here, you should use an external RTC since the Current Consumption is around 1.7uA which is 10x lower than the internal RTC.
