Wow! My big takeaway is that I guess Apple (or somebody in the middle?) is making a lot of money on batteries. I know Apple routinely charges $70-80 for a battery replacement, but this guy got one for $5!

After Samsung's issues last year, do you REALLY want to take a chance on a battery?

That's the best $70 I'll ever spend towards a part.

There is a many fake lithium batteries that have way less capacity than advertised. I have experienced it with a laptop battery. It might worth checking the real capacity of it. Also, when changing the battery, the time spent to disassemble and reassemble the phone without breaking anything might account for a lot.

Yup, lithium batteries at phone/laptop scale should be stupidly cheap.

For an example, go to hobbyking and look up what a 2100mAh 11.1v pack costs. It will be ~$8, and this is something capable of being subjected to 30+amps at 11 volts, not the nice gentle usage we give our phone batteries.

What's astonishing is that the parts he ended up using cost him $300 [1], less than half of what a new phone would cost. The parts come from recycled / broken phones, so he effectively has a Franken iPhone. I'd take it.. wonder whether it starts creaking later sometime.

It's worth noting that including purchases made for "dead ends" he ended up spending nearly $1.000

It's worth including but that's like including R&D into the cost of any device. Like saying an brand new iPhone 7 doesn't really cost $649 but really costs $100......0000 due to the R&D it took to make it. I have confidence that while the first phone cost him $1000 the second would cost him $300.

If we are looking at it like a business then your math makes sense. But as an individual, it would be cheaper just to buy a new iPhone because of the dead ends and time spent assembling the device. So yes if he did everything perfectly the first time then the cost was $300, not including labor or tools. But the actual cost is way above $1k including labor, tools, dead ends and research. A business can factor those costs as R&D as they will producing x amount of these but he is only going to produce 1 and who knows if those tools and parts will work on future projects.

I've constructed Galaxy S_ series phones from eBay for about £60 a shot by buying a lot of faulty units and salvaging good parts. It's no harder than building a PCI-based PC in the late 1990s.

They are good solid phones other than the EMMC on the mainboard which tends to fail, but good boards are easy to find in phones with smashed screens.

This was great and very entertaining. Thanks for sharing.

How much has he paid for all those parts?

He said he spent around $1000 on failures and tools. If he had done it perfectly the first time it would've cost him around $300.
