Turning off the Always-On LTPO display on the Apple Watch Series 11 (46mm) makes a big difference to battery runtime. Combined with powering it down overnight (11 PM–7 AM), battery drain stays below 20% per day, making around four days between charges achievable. The image shows the battery state at noon on day 3. Anyone pushed it beyond 4 days?
Settings: Everything enabled except GPS/Location Services. Display set to a 15-second wake (instead of 70 s), brightness at the highest setting, watch face with a mostly black background (e.g. Meridian). Connected to the iPhone via Bluetooth; cellular not used.
This Apple Watch App uses the concept of adaptive UI / progressive disclosure / semantic zooming:
The compounding chart adapts to the scenario, using a guided, color-coded view for shorter timelines and a log chart for longer ones to highlight long-term growth and the halfway point. Tap the result to cycle between total value, value increase, and percentage gain. percentmateapp.com

Percentages can be deceptive, e.g. a 13% increase in Dutch property prices means the current €9,437/m² already contains that growth.
Recovering the previous value requires reversing the calculation (not just -13%).
Gross/net mode in this app handles it instantly: €8,351.33/m² is the last year's price. percentmateapp.com

On Apple Watch, good UX often means removing controls, not adding them. Instead of a dedicated ± key in the Percent Mate app, tap the value to invert its sign.

For any compounding scenario in Percent Mate (e.g. $10,000 over 20 periods at 8%), the logarithmic chart reveals the point at which 50% of the total value growth has been achieved. In this example, that occurs around period 14 of 20.
