   @josecastillo Battery test, day 410: 2.195 volts. (Mostly 2.19, but it did hit 2.20 once). No more big voltage drop when I press the mode button, which signals to me that its steady state current consumption is higher now. That and the steepening of the red line 😬. This microcontroller operates down to 1.62 volts, which gives me optimism that this watch with the old firmware will still be with me in 2023, if only for a few days. (New firmware, green line: 3.07 volts at day 305.)
