Doing some profiling of the #flow3r badge battery for more accurate battery indicator.
And here are the results of the battery discharge profile.
The outcome will make it into firmware v1.3.
The discharge happened in 26°C room at ~650mW or roughly 0.05C which is about the average discharge in most apps.
This yields a battery runtime of roughly 11-12h with moderate use (no WiFi).
Currently the firmware reports 0% at half the capacity.
Also surprisingly the actual capacity is spot on at 2Ah.
@timonsku Using constant power is appreciated; I usually see these graph with constant current which is misleading. Do you have this graph for other loads per chance? I'm particularly curious about how voltage-SoC correlation varies with load.
