remember that SoC TDP != power consumed by the system I'm just going by how much power my phone takes to work — the battery charge level goes down if it's plugged into a 5w port instead of a 10w capable port. | 17:30:22 |
| Sage | err wait, standard USB is 2.5w, 5v 500ma | 17:30:41 |

err wait, standard USB is 2.5w, 5v 500ma That's the basic usb 2.0 spec, but there are many variants with higher power | 17:31:34 |
| Sage | this is true, but I assume mining is higher power consumption than watching youtube videos. Probably depends on screen brightness | 17:31:52 |
|  @davis_:matrix.org left the room. | 17:33:15 |
| Sage | Yeah I'm just trying to get a good idea of how much power each phone uses. | 17:33:18 |
| Sage | * Yeah I'm just trying to get a good idea of how much power each phone uses and I don't have a USB power meter | 17:33:30 |
| 若得捏 | well, assuming they're all 10W, it's still a waste of time and money if your goal is mining | 17:42:08 |
| 若得捏 | you can do far more efficient mining with a single Ryzen CPU, for much less than the cost of enough phones and electricity to achieve the same hash rate | 17:43:03 |
| endor00 | actually, 370 H/s on 10W is even worse than an old intel cpu - even those do > 40 H/s/W | 17:46:22 |
| Sage | I'm thinking they are closer to 2.5w. a 10w flashlight gets almost too hot to hold after a few minutes.
This topic keeps coming back, I'm going to have to get some tools and phones and get some actual data. | 17:46:35 |
| endor00 | so not only horribly expensive, but horribly inefficient (to the point that you're losing money without basically free electricity) too | 17:47:10 |

so not only horribly expensive, but horribly inefficient (to the point that you're losing money without basically free electricity) too and that doesn't even include the pain of labor to set them up to even run xmrig | 17:47:48 |
| endor00 | but that can be automated away with termux + a oneliner | 17:48:24 |
| endor00 | * but that can be automated away with termux + a oneliner script | 17:48:27 |
| endor00 | so that's the least of your problems | 17:48:37 |
| 若得捏 | automating wifi config, installing termux, etc etc? plus you'd need to build some complex dock to house all the phones | 17:49:02 |
| 若得捏 | so they all have power, can be manged easily, etc… | 17:49:19 |
| endor00 | (I'm only talking about automating the software part, not the hardware) | 17:49:53 |
| 若得捏 | much easier with commodity PC hardware where you can just boot from USB from the start | 17:49:55 |
| 若得捏 | plus, for a thousand phones, you'd need to manage 4 different subnets for them all to even connect to the wifi, on multiple routers | 17:51:58 |
| endor00 | You can have networks much bigger than a /24 | 17:52:54 |
| endor00 | The typical configuration is for a /24, but the actual space is 192.168.0.0/16 | 17:53:34 |
| 若得捏 | sure, it's lan so you can 10.x.x.x everything, but it's still something you have to manage | 17:53:34 |
| endor00 | As space guide put it in the past - your phones would just lose connectivity due to all the wifi noise anyway at that point | 17:54:19 |
| 若得捏 | 300-400H/s with even as few as 100 phones will only get you 30-40 kH/s, at the cost of much work, and a kilowatt of energy being used, when you get that with one or two CPUs with Ryzen/Threadripper/EPYC, at less than 300W consumption, and without the headache of managing 100 devices on the network, automating deployment of updates and config, etc… | 17:56:08 |
| 若得捏 | exactly, phones just are not worth it | 17:56:37 |
| Sage | Yeah buying 3900x is easier than reading this conversation | 18:10:36 |
