https://devzone.nordicsemi.com/f/nordic-q-a/22438/nrf51-smart-beacon-consuming-too-much-batteryHello, I developed an application for the nrf51822 Smart Beacon, SDK11 s130, that basically advertises the battery lvl of the beacon, the staus of button_1 and the number of times that button_1 was released. For handling the button events I am usingen-USTelligent Community 13Tue, 30 May 2017 20:05:38 GMThttps://devzone.nordicsemi.com/thread/88243?ContentTypeID=1Tue, 30 May 2017 20:05:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:68010eb0-f930-4eee-b5e7-2afea6bf5577luiz_campos<p>Thank you, I will try to contact support team through MyPage portal.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/88242?ContentTypeID=1Tue, 30 May 2017 19:30:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f21b4de5-b54a-4439-9f7e-90418bc2ba2eendnode<p>It could be easily some SW coding mistake as you speculate. The fact that you run <code>sd_app_evt_wait()</code> doesn&#39;t mean that you are not generating load of events which are effectively draining your battery even you are sending the application to sleep in between. The best thing is to run some power profiling (either on nRF51 DK with PPK from Nordic or with some simpler set-up and GPIO signalling of when your app is really doing something). I guess you will find out what is causing continuous wake-ups pretty soon. Alternatively you could paste more of your code here (or even entire project) - you can also submit it in &quot;private&quot; through Nordic MyPage portal - and let Nordic support team to look into it.</p><div style="clear:both;"></div>
