51822 Consuming More power than 51422

[Harsha]

HI, I am facing some serious issue in 51822. It consumes more power than 51422 on a same custom board. I am using same software for both with s130. Surprisingly the 51422 consumes 1.15 mA in system power off whereas the 51822 consumes just 2uA in power off in same circuit. I have no clue on whats happening,

Kindly help. I am using external lf crystal as clock source.

I wonder if with the same circuit (custom board) and with the same firmware, NRF51422 will consume more power (at least 10 times) than NRF51822. Please clarify.

One or two years ago I noticed that our devices had to be power-cycled after programming with Segger, otherwise they drew a lot of power (and drained three parallel CR2032 batteries in about 30 days. - these where beacons)

I think this had to do with the JTAG component in the nRF still drawing power after programming its internal FlashROM.

You could at least verify this and report back here.

Hi Martin, In the original post that was a typo. So I changed it. Can you tell me how to bring the chip out of debug mode?. I tried all possible ways. Also I dont think there is a hardware issue. I have around 40 pcbs. All pcbs consumes same power with 51422. Expecting your reply.
