## Achieved power consumption recap:
(Need to work on sleep current :-( )
| Mode | Current draw | Estimated battery life (600 mAh lipo) |
|--------------------------|--------------|---------------------------------------|
|Active (40MHz clk)<br>(No BLE / No WiFi) |~52 mA | ~11 hour |
|Active (240MHz clk)<br>(No BLE / No WiFi)|~72 mA | ~8 hour |
|Sleep |~4.5 mA |~5 days and 12 hours |
|Standby |~1.8 mA |~13 days and 15 hours |

|--------------------------|--------------------------|---------------------------------------|
|Active (80MHz clk)<br>(No BLE / No WiFi / Screen on) |~54.51 mA | ~11 hours |
|Active (160MHz clk)<br>(No BLE / No WiFi / Screen on)|~64.7 mA | ~9 hours |
|Sleep (Clock is OFF / No BLE) |~3.97 mA | ~6 days |
|Sleep (40MHz clk / With BLE) |~49.20 mA | ~12 hours |
|Standby (Not available) |~1.8 mA |~13 days and 15 hours |
