Don’t base your product development on datasheets. It cannot be said enough, but when it comes to design for low energy consumption and long battery life, it is unreasonable to base the product development on data for typical conditions. Your application, design and product integration is far from typical, and it is changing during the process; hence the energy profile is continuously evolving. Picking the right battery for the IoT device depends on understanding the energy profile.
Check out a few best practices on how to do this from our keynote at The Things Conference 2020!
