Make sure 250mah (current charge on DK2) is enough for 4 days of use with no charge

3 questions:

1. how much battery consumption ?

• on the normal mode (ble connected + ble advertising)
• on the deep sleep mode

2. what is the top3 functions that consume the most battery ? how much
3. what is the top3 module(e.g. ble, mic, button, ...) consume the most battery ? how much

Question 1:

• BLE disconnected state: ~35mA
• BLE connected state: ~6.5mA
• Low power state: ~1.15mA

Hi @beastoin The different between BLE connected and BLE disconnected states is :

• When BLE connection is disconnected, we start to writing data to the SD card.
  So SD card is the most power-consuming module.

4. focus on the ble connected state (as the main usecase). what function / module consume the most battery? e.g button / button state watch function
