I think the figures are correct. 120mW is for a Pi4 HALTed (and 3V3 powered down). From your description, yours may be HALTed, but 3V3 is still active. Read the rest of this thread for an explanation (POWER_OFF_ON_HALT setting). I read about it, but the PI2/PI3 deliver 3V3 while they switched off a...

Re: RPi4 poweroff - still on?

Are you measuring the input with the Pi powered down? Documentation here suggests that a halted Pi4 draws around 120mW! In use, the actual PSU power output will be rather less than the power input. Without a power meter between the PSU and the Pi, you don't know what that power output is -- the max...

It's connected to 5V via a diode and supplies power to the power led. Strangely, the LED is turned off by shorting it out - kind of weird. Also of concern is the 470R R13, which appears to do nothing but sit there and burn 10mA for no apparent reason. With GLOBAL_EN shorted to ground, turning off t...

The datasheet for the XL4015 states that the minimum input voltage is 8V, you therefore need at least 8x 1.2V cells for reliable operation, that's assuming you discharge to 1V per cell. Thats right better 8 Cells, but its for reaching the full 5 Ampere continously output. The 8V just required for t...
