Hello all,
I am looking for a piece of test equipment that is used to determine the amount of power consumption for battery-powered iOT and embedded devices. The device basically replaces the battery of the UUT and essentially makes very fast current measurements and builds a power consumption profile which can be used to determine a devices expected battery life.
I think most of us just do the best we can at estimating our product's projected battery life based on what we have for power usage calculations. A device like I am looking for should provide a very accurate battery life prediction based on actual energy profiles (sleep, active, xmit, rcv, etc.) over a certain sample period.
There seems to be a few different products on the market. Here's a link for several related products:

Does anyone have any experience with this type of logger/monitor?
TIA
