I don't think the point was for other people to recreate a bitcoin miner - no one will have 4+ S5s laying around to use anyway. It's just to show that they still have some computation power that can be used.

But the post you are replying to is showing that they literally can't be used for this.

I think they quite literally can be used that way. Practically? No.

They can mine bitcoin. They can't be used for mining bitcoin. It proves nothing whatsoever about the utility of old S5s, any more than this[1] shows that old 60s mainframes "still have some power that can be used".

What does that prove then? That they can do computations?

The Galaxy S5 came with a Snapdragon 801, the same I have in my Oneplus One and it's plenty fast to this day.
It runs current Android (Lineage) and I haven't yet even thought about upgrading my phone. I only had to change the battery recently as last through a day anymore, but now there is not much more to desire.
In comparison, the Antminer S9 will do 13Th/sec for about 1275W. This gives a hash rate of 0.098 J/GH.
In essence, an actual bitcoin miner is about 15,000 times more efficient. I'm all for recycling, but this is not an effective solution.
Why not release the documentation for the displays for use in other products, or release technical documentation for other parts of the board? This would be a much better step in recycling instead of building an anemic space heater with bitcoin.
