Need real power consumption data
-
The M5stack is interesting but many details and specs are missing. Perhaps the makers can help:
- what is the power consumption when OFF ? Does pressing the power switch twice actually shut the device OFF -> power is zero ?
- what the power consumption in deep_sleep ? I get variable amount from 17 to 40mA using a USB power meter with no battery.
- Is is possible to measure battery voltage ?
The M5stack is a battery powered device but very little support exists for conserving battery power, saving power, and estimating remaining battery life.

I'm getting
0.29a switched off.
0.39a running factory test.
Using a USB power meter.to measure battery you need a test meter
Can't measure this tonight as cant find small allen wrench. -
Does anyone now have any updates on this question? It would be really helpful to get some more info.

I haven't had the budget to buy anymore items to test but I'm just using a cheap inline usb power meter.
-
MKI camera = 0.1A
-
MKII (PSRAM) camera
Standby = 0.1A
connected = 0.14A 00592mah
5.18V
Running a lot cooler then the MKII don't have anything else to test so that's all I can give.
Measurements taken with a Keweisi branded usb test meter.
