Apple's iPhone 6S specs are going to be a major focus of its forthcoming smartphone, because this is an "S" update that reportedly shies away from changing the design.
In fact, the iPhone 6S dimensions are supposed to be exactly the same, so almost everything that's new about this phone is happening on the inside.
That may sound like boring news, but the new iPhone and the iPhone 6S Plus are rumored to make major leaps thanks to more powerful internal specs and features, all for a steady iPhone 6S price.
Anyone who wants a better camera, faster processor, more RAM and boosted battery life is likely going to be pleased with the Apple's iPhone 6S announcement on September 9.
iPhone 6S specs: Processor
There's every reason to believe that the new iPhone 6S processor will be called the Apple A9, as it follows a sequence, from last year's A9 in iPhone 6 back to 2010's A4 in iPhone 4.
The bigger question is, just how powerful will this Apple-designed System-on-a-Chip really be? Plenty powerful, according to a bunch of unconfirmed benchmark leaks.
iPhone 6S specs are tipped to set new records, with rumored Geekbench scores that claim it'll be 20% to 30% faster, even though the chip uses smaller 14-nanometre FinFET technology. That's a good thing in the world of processors.
The exact number really depends on which leaked Geekbench 3 benchmark scores you want to believe, and which are fabricated. Right now, it's hard to tell.
For consumers, Apple's third 64-bit mobile chip will translate into apps loading faster and high-intensity games playing more smoothly. Those occasional hiccups we all experience could be eliminated.
iPhone 6S specs: RAM
Apple is finally going to double the amount of RAM from 1GB to 2GB in the iPhone 6S, claims just about every single report we've seen.
That's excellent news for anyone who has experienced iPhone slowness in the past, and has been envious of the 3GB RAM and 4GB of RAM in several new Android phones.
It's more than a number. Expect menu transitions to be more fluid and the iOS 9 keyboard to not lag behind your touch, especially at the end of your phone's drawn out two- or three-year lifecycle.
The 2GB of RAM in the iPhone 6S is long overdo, especially among multitaskers who want to load several apps at once without constant app refreshing issues.
iPhone 6S: Internal storage
Here's where the iPhone 6S may let you down: its internal storage will likely start at 16GB again, even though that amount of space isn't enough for average users.
It wouldn't be so bad, except the iPhone 6S price will likely make it expensive to upgrade to the higher tiers, and iCloud isn't completely viable because it's more expensive than Dropbox and Google Drive.
Apple did us all a solid last year by making 64GB the same price as the now eliminated 32GB storage size, but we'd rather see a 32GB iPhone 6S for the same price at the 16GB model instead.
The the new iPhone is expected to once again max out at 128GB, for anyone who likes to take all of their media files on the go and can afford that gold Apple Watch while they're at it.
iPhone 6S: Graphics chip
The new Apple TV may focus on games and controllers in its expected update on September 9, but the iPhone 6S is going to be right up there with the set-top box when it comes to graphics.
Imagination Technologies, Apple's steady manufacturer behind the iPhone GPU, already unveiled its Power VR Series 7XT chipset late last year. It's been ready for months.
It came out too late for the iPhone 6 and iPad Air 2, which use company's PowerVR Series 6 GX6450 and GX6850 GPUs, respectively, with still impressive results.
Two things are highly likely: the stepped-up Power VR Series 7 will be incorporated into the iPhone 6S, and we're in for press conference-lengthening 3D game demos at the Bill Graham Civic Auditorium this Wednesday.
iPhone 6S: Durability
There's more evidence that the iPhone 6S will be physically stronger than the iPhone 6, and the same will apply to the iPhone 6S Plus over the troubled iPhone 6 Plus.
A test of what's said to be an iPhone 6S prototype shell turned up in a video last month, and the bend test suggested that the iPhone 6S will be more than two and a half times more durable.
It's a safe assumption that Apple will want to reassure skeptics that the there won't be another repeat of BendGate. Adding zinc-infused aluminum 7000 series would be a remarkable way to just do it.
iPhone 6S specs: screen, size, camera and battery
There's nothing out there that says Apple's going to change the sizes of the iPhone 6S screen from the 4.7-inch display unveiled last year, and the same goes for the 5.5-inch iPhone 6S Plus.
That's okay because the iPhone 6S may finally be bumped up to a Full HD 1080p resolution, and we'd much rather have that than a change to the screen size.
It's not close to the 2K resolutions on several Android phones, or the 4K display being touted by the new Sony Xperia Z5. However, it's a step up from the iPhone 6 1334 x 750 pixel spread.
The iPhone 6S Plus is likely to remain at a 1920 x 1080 resolution, but both new phones could sport a brighter, more color accurate screen. That's even more important these days in direct sunlight.
Moreover, the new iPhone displays are supposed to be loaded with Force Touch technology. iPhone 6S Force Touch or 3D Touch is said to add pressure-sensitive interfaces.
Hidden submenus or word definition shortcuts could pop up with longer and harder presses, exactly like we've seen from the Apple Watch and new MacBook trackpad, for a helpful, but minor addition.
iPhone 6S: Dimensions
Good news for case manufacturers and consumer who already bought an expensive sheath for their iPhone 6. Apple is said to be keeping the iPhone 6S the same length, width and height.
It'll again measure 138.1 x 67 x 6.9mm, or 5.44 x 2.64 x 0.27in, which is still .1mm thicker than the Samsung Galaxy S6. That's okay, because phones need battery features, not ultra-thin chassis, according to consumers we've talked to.
The iPhone 6S Plus is also expected to mirror the 6 Plus dimensions, at 158.1 x 77.8 x 7.1mm, or 6.22 3.06 x 0.28in. The Samsung Galaxy Note 5 has the same thickness, again, as if that matters.
There's one report that says Apple will increase the size by an almost indistinguishable measurement to the naked eye, due to its inclusion of Force Touch components, but that hasn't been substituted just yet.
iPhone 6S: Camera
Apple is expected to at last step away from its 8MP camera by including an overdue 12MP rear camera and 5-megapixel front-facing iPhone 6S camera. It's just in time.
Samsung has really raised the bar, not only with a higher megapixel count, but better image processor software and photo editing tools in its Samsung Galaxy S6 and Note 5 phones.
In other words, don't expect Apple to make an incremental update with its camera lens and module this time around. Instead, we may see it leap closer to "DSLR-like photo quality" in a way that doesn't make that statement sound like typical marketing hype this time around.
iPhone 6S: Battery life
There are conflicting reports on whether or not the iPhone 6S and iPhone 6S Plus battery life will be much improved over the all-day power of last year's phones.
Rumors have always pointed to better battery life thanks to several hardware and iOS 9 software optimizations, but in recent days, we've been hearing that the actual battery capacity in the new phones will be smaller.
The reduced battery size reports come from sources in China, so nothing is confirmed, and Apple isn't likely to tout these specs on stage during its press conference if that's the case.
We'll know for sure when someone cracks open the iPhone 6S in a teardown when the phone actually launches. But don't worry too much. Apple is more likely have tweaked its components and iOS 9 operating system just enough to meet your all-day battery life expectations, regardless.
