High? I don't think so. Very VERY few items that the iPhone 12 mini cannot do that iOS 15.7/16.0.1 offer in Software. Value is value and with only 2 options for the mini, Apple knows this. Let's just hope Apple is using the higher resale fees as R&D for a better mini at 5.4" to debut later.
I see nobody complaining about refurb pricing on Xr, 11/11 P/11PM or 12/12P/12PM devices, hmmmm.
Tim Cook and the executives of the iPhone lineup REALLY needs to see this!
Personally, imho, I think the lack of functionality in the iPhone 14 Plus will not have that model sell any more than either the 12/13 mini did. If this turns out to be fact, Apple really needs to look at their lineup a LOT better.
Funny how the SE OG (an iPhone 5s size + Acpu, RAM, storage options), the SE 2 an iPhone 6S/7 (again with CPU, RAM, and storage options; being the same really), and the SE 2 (yet again with cpu, RAM, colour and storage options) is 'OK' for Apple to keep, but the mini no - when neither mini was EVER nor properly advertised by Apple.
Apple should rid themselve's of TouchID on devices. It's contradictory to their FaceID being more secure, just like when the 5S & 5C launched in the same presentation, Apple mentions recycling yet 'unapologetically plastic' with a British accent sold the 5c.
Again ... what can the 12 mini NOT do in iOS that the 13 mini can?
Hardware:
FaceID gen 2/3 - slightly faster, barely noticeable each time you use it.
Battery - is larger along with a CPU more efficient in the 13 mini
- Sensor-shift optical image stabilization for video
- Smart HDR 4 for photos
- Photographic Styles
- Dolby Vision HDR video recording up to 4K at 60fps
- Cinematic mode video recording with shallow depth of field (1080p at 30 fps)
(EDITED
hardware differences to be accurate vs perceived).
Software:
Hmmm. Nothing really. Yeah absolutely nothing.
Does this affect value - no not 1 bit, not until iOS starts to no longer support the 12 mini and only the 13mini as the minimum device. Until then it's still a great device - but for both I do recommend a MagSafe compatible battery extender for a long daily use, where 6hr+ talk time or more is needed.
Fam & fellow countryman, we all WISH this to happen, but I'm not so certain it will, not for the next 2-3yrs.
It's unclear if it will have Face ID. A new report from MacRumors based on information from Display Supply Chain Consultants (DSCC) analyst Ross Young...
www.gsmarena.com
If Ross Young is correct, it's likely the Xr frame will be used - if so two major things will occur:
Rounded smooth sides doesn't fit the existing iPhone hardware design of the last 2yrs

6.1 inches screen, this could - even with TouchID on sleep/wake side button will impact iPhone 14, 13, and any 12 sales (retail, online or refurb) on Apple's site.
Other findings:
Weight will be significantly heavier as more aluminum than the SE/12-13mini. Significantly heavier by 50 grams:
144 g (5.08 oz)/ 194 g (6.84 oz)!
- iPhone 12/13 mini respectively (135 g (4.76 oz)/
141 g) are BOTH
Height significantly taller model if it'll use Xr frame :
150.9mm vs 138.4 ( iPhone 12/13 mini's are
131.5 in height by comparison).
Screen resolution goes up:
SE3: 750 x 1334 pixels, 16:9 ratio (~326 ppi density), Xr :
828 x 1792 pixels (~326 ppi density) Density of pixels being the same - not ideal on a larger screen as it'll be LESS sharp!
- iPhone 12/13 mini's have
1080 x 2340 pixels, 19.5:9 ratio (~
476 ppi density)
A-Series chip:
Both the SE3 and the 13 mini have the same Apple A15 Bionic (5 nm) chip having
Hexa-core (2x3.22 GHz Avalanche + 4x1.82 GHz Blizzard). This is significantly faster than the iPhone 12 mini's
Apple A14 Bionic (5 nm) having Hexa-core (2x3.1 GHz Firestorm + 4x1.8 GHz Icestorm). Trying both mini's I could tell a substantial and noticeable different in iOS 15.4 launching & running Island War game on each, especially when zooming in on battles of 260 characters on the field. This is NOT an intensive game, just rending individual polygons pushed limits - with minimal apps frozen in background.
Now I'm not certain if TSMC/Hon-Hai have the Xr molds still in stock, so it only makes sense Apple goes with the A15+ chip in a 5.4" screen iPhone 13 mini for the upcoming iPhone SE 3 for late spring 2023, removing the 13 mini from sales stock by then. This could also mean economies of scale using the 2nd gen FaceID to the SE lineup along with a much sharper screen, more displayed on the screen due to the higher pixel count and for those that scream for the TouchID Button - accessiblity has that solution for you for over a decade now. Just my thoughts and findings.
