https://devzone.nordicsemi.com/f/nordic-q-a/70121/turn-off-twi-and-gpioHi, How do I configure Zephyr to turn off TWI and GPIO while in sleep mode? Once I enable those, idle power consumption doubles. I tried using device_pm_enable() on initialization , and then device_pm_get_sync() and device_pm_put() every time i useen-USTelligent Community 13Tue, 05 Jan 2021 15:19:07 GMThttps://devzone.nordicsemi.com/thread/287557?ContentTypeID=1Tue, 05 Jan 2021 15:19:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:acda3428-4168-450b-b5f5-3dcaf89e66c0plotkin1996<p>Never mind, it did turn off automatically, but my interval between TWI usage events was too small (5 seconds) and it looks like Zephyr doesn&#39;t enter full power save if a timer event is expected so soon. Increasing the interval brought consumption down right after the timer event.</p><div style="clear:both;"></div>
