I have always valued structured consistency and efficiency in my training, and it is interesting to see that same logic applied to eMTB battery management. For those using Bosch, Shimano, or Specialized systems, maintaining a high cadence between 70 and 90 RPM is recommended for better efficiency. It makes sense to treat the motor like a cardiovascular system where a smoother, faster pedal stroke yields better results.
Regarding battery health, storing lithium-ion batteries at a full 100% charge can reduce long-term capacity, which makes the use of management apps a tempting option for longevity. However, I wonder if these automated tools are actually helpful in practice. Do automated battery management apps actually provide a better experience than manual mode switching?
Relying on automated apps is a gamble that usually trades precision for convenience. The problem is that software algorithms often can't account for the specific gradient changes or technical sections you're facing in real-time; they smooth things out based on a predicted route, but they don't know if you're about to hit a 15% pitch change that requires a sudden burst of torque.
Manual mode switching gives you the control to match the motor's output to your actual physiological output and the terrain. If you're maintaining that 70 to 90 RPM sweet spot for efficiency, you want the motor to assist your rhythm, not fight it with aggressive, automated shifts in assistance level that might throw off your cadence or cause you to hunt for a gear. Automation is fine for storage or long-term maintenance, but when you're actually on the climbs, you need the gear and power delivery to be as predictable as the tooth jumps on your cassette.

That is exactly the problem. If the goal is to treat the system like a cardiovascular engine, any sudden variance in assistance is like a glitch in your interval timing. When the motor fights the rider, you lose that smoothness in the pedal stroke, and you end up wasting energy correcting your balance rather than maintaining that 70 to 90 RPM efficiency. Predictability is everything when you're trying to dial in a specific output.
