https://devzone.nordicsemi.com/f/nordic-q-a/121224/optimizing-power-consumption-with-timer-peripheralHi, I am currently working on evaluation of the nRF52810 for a simple project which requires a very low power consumption. I searched and found an example which I modified to my needs. The function is very simple - start the chip, initialize TIMER1en-USTelligent Community 13Wed, 07 May 2025 07:20:49 GMThttps://devzone.nordicsemi.com/thread/534209?ContentTypeID=1Wed, 07 May 2025 07:20:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:37027774-6c93-4c54-af06-bf9b43c138ccDavidV<p>Yup that fixed it for me. Once I changed everything to use the RTC timer, the power consumption dropped to some 29 uA. Thanks a lot for the answer!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/534198?ContentTypeID=1Wed, 07 May 2025 06:49:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:be3a6ece-764c-4026-8302-1cf63acb9ad8Edvin<p>As <a href="https://devzone.nordicsemi.com/members/emil-lenngren">Emil Lenngren</a>&nbsp; says, the RTC is less power hungry than the TIMER peripheral. Replace NRF_TIMER1 with NRF_RTC1. Some of the registers may be a bit different, but the functionality is roughly the same. The frequency is a lot lower, but based on your prescaler for TIMER1, that shouldn&#39;t be an issue.</p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/534152?ContentTypeID=1Tue, 06 May 2025 16:17:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:28b39659-79a0-4c0a-94cf-ef9174d38bedEmil Lenngren<p>Maybe you can use a RTC peripheral instead? The TIMER peripherals require the high frequency clock to be active, and thus results in pretty high power consumption.</p><div style="clear:both;"></div>
