About 41 euro cents per day->57€/140 3360 is the number of hours in 140 days.

You are, in fact, correct. I have no idea why I converted 140 days into hours... Still, my point remains unchanged: I, at least, value reliability and uptime more than ~43 euro cents.

43 cents / day is >150 a year, that's not to be sniffed at.

Actually, at 150 / year you can rent a VPS (or two!) as well, always-on etc, which... kinda shows how skewed consumer price for electricity is.

Something's not right. I own both a passively cooled 2016 Mini PC OLOEY Intel Core i7-7500U (as a home media center) and a 2023 Minisforum UM690 (for work and it's amazing btw), and they both use about 7 watts when idling (screen off). How op is using 43 watts for an idling media center is just beyond me, he must be using a 1978 Intel 8086, right? Anyhow, 4 watts is still far better than 7 watts and this is a great a…

It’s the hard drives that are staying on.

I have a HP Microserver N40L with 4 spinning disks. Last time I measured, I'm pretty sure it was consuming around 40W.

I guess CPUs have gotten better in the last 10 years ;)

Assuming the power management for the CPU etc is working, spinning drives likely use c.7-10 watts per drive when idle but not spun down.

Probably a combination of wrong configuration of CPU scheduler and not sleeping hard drives.

Some of the hard drives do not advertise their sleep capabilities over SATA, and hdparm ignores these drives unless you force for sleep.

The power saving is not because of Android it is because of the ARM arch being used under the hood. And ARM servers for power saving purposes are very much a thing already.

> The power saving is not because of Android it is because of the ARM arch being used under the hood. [citation needed] Based on my understanding, the underlying OS has way more to do with power usage than the instruction set, and AFAIK Android has tons of optimizations specifically geared towards reducing battery consumption (and therefore power usage) on mobile devices. With that said, it's true that, in practice,…

Intel Atom, admittedly a decade ago, was 2 - 11 watt depending on model.

I understand now that they have been rebranded as Pentiums, and the envelope is more 10-20 watts.

Or the cost of running water pumps for public fountains

The romans had water fountains and no pumps. Perhaps you underestimate gravity.

Did I mention the Romans. I was talking about modern fountains some of which have pumps

My desktop PCs have always been idling at more than 50W. Granted, my newest one is from 2011 or so.

I use an old Intel Macbook to selfhost this kind of services. The idle draw is around 2W and you get a free UPS if your battery is still working.

The sleep management on macOS is really well done and you don't even need a magic packet to wake the computer. You can configure `pmset` to wake on modem access (ring).
