About Battery life in sleep mode and wake up modehttps://test-devzone.nordicsemi.com/f/nordic-q-a/29154/about-battery-life-in-sleep-mode-and-wake-up-modeHi, I am trying to bring the nrf52 in sleep mode for 12 hours and broadcasting mode for other 12 hours. The idea behind it is to save the battery for longer life. What way should I go in order to achieve it without using external RTC.en-USTelligent Community 13 Non-ProductionWed, 01 Jun 2022 10:49:45 GMTRE: About Battery life in sleep mode and wake up modehttps://test-devzone.nordicsemi.com/thread/370402?ContentTypeID=1Wed, 01 Jun 2022 10:49:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d4fbd269-072f-4bae-a871-5425b06273bauser20690<p>This is the ticket I was referring to in my previous answer:</p> <p><a href="https://test-devzone.nordicsemi.com/f/nordic-q-a/22413/let-the-nrf51822-wake-up-after-3-hours">https://devzone.nordicsemi.com/f/nordic-q-a/22413/let-the-nrf51822-wake-up-after-3-hours</a> </p> <p>Br, <br />Joakim</p><div style="clear:both;"></div>RE: About Battery life in sleep mode and wake up modehttps://test-devzone.nordicsemi.com/thread/370112?ContentTypeID=1Tue, 31 May 2022 07:28:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:02621e42-89d2-4d52-8ba6-4e7087ff6059user108993<p>Not opening share document .</p><div style="clear:both;"></div>RE: About Battery life in sleep mode and wake up modehttps://test-devzone.nordicsemi.com/thread/115863?ContentTypeID=1Fri, 22 Dec 2017 11:00:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:37c4e7b6-8613-406f-9c80-70b2725843e0user20690<p>Hi Dhaval!<br /> Take a look at <a href="https://devzone.nordicsemi.com/question/142255/let-the-nrf51822-wake-up-after-3-hours/?answer=142654#post-id-142654">Sigurd&#39;s answer</a> in this case.
