https://devzone.nordicsemi.com/f/nordic-q-a/87536/how-can-i-read-battery-level-on-custom-board-nrf52833Hi, I&#39;m developing an application tracker device using 2 libuartes, pwm, ble and now I am going to approach reading battery level. After I research on dev zone but I only got the blog &quot;how to read battery&#39;s voltage ?&quot;. I planned using Saadc to read batteryen-USTelligent Community 13Wed, 04 May 2022 10:11:54 GMThttps://devzone.nordicsemi.com/thread/366157?ContentTypeID=1Wed, 04 May 2022 10:11:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4d498754-64f4-44b2-b2c5-7bdc97bd6b16J&#248;rgen Holmefjord<p>Hi,</p> <p>Battery measurement and battery level is showcased in the&nbsp;<a title="Proximity Application" href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/ble_sdk_app_proximity.html?cp=8_1_4_2_2_21">Proximity Application</a>. This uses the SAADC to sample the battery voltage, converts the voltage to battery level from a defined battery characteristics curve, and expose this over the BLE Battery Service (BAS). If you have a different battery characteristics or supply voltage range, you need to change the implementation of battery_level_in_percent() in app_util.h.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
