iPhone 15 Pro Teardown Reveals Internals, Battery Capacity, and More

Not surprised at all that apple reduced the size of the battery. Every year I say the same thing why not increase battery size instead of decreasing it every year?

They continue to add more and more features each year that takes more and more battery and every year battery decreases.

Except they didn't.

Is the requirement "replaceable" or "swappable?"

To me " replaceable" means I can open up the phone using common inexpensive tools, remove the battery and install a new one. The old one is discarded/recycled. The 15 may be a step towards that, with the reportedly easily removable back glass.

"Swappable" means I can carry a spare around and I can pop off the first one with no tools and pop on the second one. They are designed to be easily swapped back and forth.

I think the EU needs to really clarify that statement. Will it be easily swappable like what you can do with something like the old Samsung Galaxy III phone? Or will it be user-replaceable where by undoing a few screws, you can open up the phone, easily replace the battery, and close it up again?

So 3nm means absolutely nothing. Got it.

Umm... 10% faster CPU (claimed, but early benchmarks actually put it closer to 15%), 20% faster GPU, 100% faster neural engine, that's not nothing. 3nm reduces power draw per transistor, and they added, let's see... 3 billion transistors to the chip vs the A16. Early reviews say battery life while gaming is significantly better, despite Apple not making any different battery life claims this year. They focused on beefing up the GPU and neural engine rather than CPU, because let's face it, the CPU is plenty fast for most mobile tasks already. Oh, and don't forget the integrated USB 3 controller and AV1 decoder.

From the 3 billion, probably around 2 or more are just for the extra GPU core. Same happened in the past. Look A14 vs A15. Meanwhile A16 increased 1 billion with no extra cores which is actually huge. The CPU is ~10% when you compare best A17 and the best A16 results. Also the battery life is worse pretty much. The A17 Pro is very power hungry when it peaks. There was great video from Geekerwan (actually the highest result is by him with super strong cooling solution to achive it)

I wonder how much extra thickness is added with the black coating/tape that Apple wrap all the components in? It looks very snazzy, but does it serve any purpose beyond aesthetics?

The black thing is not new. It's graphite tape which helps with heat dissipation. It's cheaper than proper copper cooling like high-end Samsungs.

Oh yeah I know it’s not new, I think the first thing I saw it on was the Xbox One. Interesting that it helps with heat dissipation, that’s definitely something quite handy then.
 
Again I don’t really care I have the iPhone 14 Pro Max so I don’t have to deal with it. That’s why I’m glad I bought last year and not this year.

The battery is bigger …but life is the same despite going to a smaller die size. Is something broken about the A17 that apple is avoiding? There are additional heat covers for the processor. Is the A17 a bust?

They focused on performance this year and will probably introduce stacked battery tech to give next year’s iPhone 16 Pro/Pro a significant boost in battery life.

What everyone wants to know: Does the iPhone 15 still have a plastic spacer like the iPhone 14? :p

Exactly. Everyone making excuses about better use of space has no argument until it’s removed from every model. If it’s still present in any model, they aren’t designing that space to be used for anything else. The fact that they are still shipping every model except the US one with a SIM slot shows that this is not at all about space savings and more about network operator cartel business maneuvering.
 
Best teardown video so far. It includes comparisons to iPhone 14 Pro Max and U.S. vs. China logic boards.
