Having examined the esp8266 and esp32 power consumption in detail it is time to compare the two.

With a few more hacks the esp32 light-sleep power consumption can be pushed to the limit. This post explores the limit and calculates light-sleep mode run-times.

Dynamic frequency scaling allows the esp32 to go into light-sleep mode when it is idle.

The esp32 can also maintain an association with an access point while going to sleep on its own when it is idle. Is this a good alternative to periodically waking up from deep-sleep?

In order to test the low-power performance of the esp32 I had to acquire a few boards and I didn’t really like any of them.

Periodically waking up from deep sleep and sending a short TCP message is interesting, but how does the esp32 perform in a real scenario where it communicates with an MQTT server?

The long probing for the access point can be optimized away. In addition, it’s not smart to use open access points, so it’s time to measure the cost of security!

The esp32 is the successor of the esp8266 by Espressif. It is much faster, has two cores, more memory, more I/O, more everything. Does it also have more low-power Wifi mojo?
