The ‌iPhone 17 Pro‌ and ‌iPhone 17 Pro‌ Max will need to be upgraded to ‌iOS 26‌ version 23A345, which is the update that Apple just released.

It's not clear what's in the new version of ‌iOS 26‌ for the ‌iPhone 17 Pro‌ and ‌iPhone 17 Pro‌ Max.

The ‌iPhone Air‌, ‌iPhone 17‌, ‌iPhone 17 Pro‌, and ‌iPhone 17 Pro‌ Max will start arriving to customers on Friday, September 19.

After two days, my standby battery drain has reduced, but every time I actually use the phone, it warms up and the battery percentage counts down like a timer. Thanks Apple, thanks a lot. But hope this lasts only a few more days instead of being permanent.

MacRumors people: "It's indexing!"


Me: "I know! Just let me vent about it."

Kinda embarrassing
Not really?
Most phones that are being delivered on launch day were packaged up and had the software flashed onto them likely about a month ago, I’d much rather my first experience using a phone be with a build from now, not a month ago.
Even the latest public release for all phones of 26.0 is 11 builds newer than what was flashed on the 17 series, and even the first RC after the event was still 10 builds newer.
This new day one update build is 15 builds newer than what comes preinstalled.

Many iPhones over the years (including the 5s) had day one updates or updates that were really close to the time of release. It happens.

Google's Pixel phones usually have day one updates. Samsung's phones often do too. Game consoles, TVs, etc. all do too. Hardware gets locked in at some point with an OS installed. New bugs or security flaws are found, requiring a patch. Or, the software has otherwise been updated. This is the nature of software and product development.

If companies wait until software is perfect, they'll never release any products.

Probably for the photo black squares and squiggly lines issue, eh?

Weren't they going to eliminate this need by updating while they were still in-box?

I have the same question. Do we update the 17 before we transfer the files from our current iPhone?
I always follow whatever order they instruct when setting up a new iPhone. My Air is on its way I couldn't be more excited for the new design!
