Cost-efficiently match the energy source to the product and use scenarios. Validate batteries as second source, for extended warranties or second life.
The knowledge of the root cause of the problem cannot really be stated in money. Selling a sensor that sometimes and randomly might fail is simply not an option.
Like any small change in software or hardware can lead to errors and significantly higher power consumption, an instantaneous correction is crucial for successful product development.
At the end of each of [the design’s] iterative cycles, there is a power consumption optimization step pre-delivery. This way power optimization reaches its optimum at every step of the way and is, therefore, more manageable.
