iOS Device Summary: September 2016 Updates

I’ve updated my iOS Device Summary with hardware announced at the Apple event on September 7, 2016.

Check out the iOS Device Summary page for more info about the idea behind the summary as well as PDF downloads—including optimized files for printing.

A few notes:

Sometimes fall brings new iOS hardware across all product lines. This year, only new iPhone versions were released.

In terms of legacy hardware support, iOS 10 drops support for devices running the A5 and A5X processor. This includes iPhone 4S , which means that there are no devices with a 3.5-inch screen that support iOS 10.

.Don’t feel badly for devices with the A5 chip—they have had a very good run. The iPhone 4S debuted running iOS 5 and iPad 2 debuted with iOS 4.2.1. Both were supported up through iOS 9.

Time will tell if the next version of iOS drops support for A6 and A6X devices. When support for those devices is dropped, iOS devices will be 64-bit only.

In the meantime, of course, it is important to test on older devices running the oldest version of iOS that you support.

I hope you find this version of the chart helpful. •

tvOS and watchOS Device Summary: April Edition

After updating the popular iOS Device Summary in March, it seemed the beginning of April would be a good time to introduce summaries for devices running the most recently introduced Apple operating systems: tvOS and watchOS.

I hope you find these as useful as I have. •

iOS Device Summary: March 2016 Updates

I’ve updated my iOS Device Summary with hardware announced at the Apple event on March 21, 2016.

Check out the iOS Device Summary page for more info about the idea behind the summary as well as PDF downloads—including optimized files for printing.

A few notes on the newly introduced hardware:

The introduction of the 9.7-inch iPad Pro means even more users will be putting the Apple Pencil and Smart Keyboard through its paces. Even if your app is not a drawing or text-centric, you might consider having at least one size of iPad Pro with these accessories for development and testing.

The iPhone SE brings paris a well-established iOS screen resolution with a faster processor. From a testing perspective, apps that perform well on previous 4-inch devices should perform even better on the new hardware.

Only the display of the 9.7-inch iPad Pro has the new True Tone feature.

The Night Shift feature introduced in iOS 9.3 is available to devices using at least an A7 chip—every device on the 64-bit side of the divide on the summary chart.

iOS Device Summary: Fall 2015 Updates

I’ve updated my iOS Device Summary with hardware announced at the Apple event on September 9, 2015. This edition drops iOS 5 and A4-based devices to make way for iOS 9 and the A9 and A9X.

(This update has taken a little while—I’ve been busy helping to build a new cloud computer at Upthere.  I’m excited to say that we launched yesterday. I encourage you to learn more and join the beta at upthere.com.)

Check out the iOS Device Summary page for more info about the idea behind the summary as well as PDF downloads—including optimized files for printing.

The biggest news this fall is the iPad Pro, which introduces the largest iOS screen size ever, but also two new Apple accessories that may be important to test your app with: the Apple Pencil and the Smart Keyboard. On the other new devices, iPhone and iPad screen resolutions remain the same and get faster processors. From a testing perspective, things that perform well on last year’s models should perform even better on the new hardware.

It is also interesting to note that all of the devices that can run iOS 6 are on the 32-bit side of the processor divide.

I hope you find this version of the chart helpful. •

iOS Device Summary: A8 iPod Touch Update

I’ve updated my iOS Device Summary with the newly announced iPod touch.

You can check out the iOS Device Summary page for more info about the summary plus PDF downloads—including optimized files for printing.

For developers, the iPod touch has been a useful, relatively inexpensive compact device for testing. The previous model was released almost four years ago and sits at the very low end of devices that support iOS 8 and iOS 9.  The new sixth generation iPod touch is a welcome addition as a more affordable testing device with a recent 64-bit processor.  Like previous generations, the new iPod touch has a 4-inch display, so an iPhone is still needed for on-device testing of larger screen resolutions.

It is interesting to note that every iOS device that Apple currently sells, except the iPhone 5c, has a 64-bit processor.

This also means that if you need to acquire older models for testing iOS 8 and iOS 9, you will need to turn to refurbished or used devices.

I hope you find this version of the chart helpful. •

iOS Device Summary: iOS 9 Update

I’ve updated my iOS Device Summary with the iOS 9 info Apple has publicly posted.

Check out the iOS Device Summary page for the rationale behind the summary plus PDF downloads—including optimized files for printing.

Some things to note from WWDC announcements and Apple product lineup changes:

All devices that support iOS 8 will also support iOS 9.

Apps are currently required to support both 32-bit and 64-bit processors. With iOS 9, the App Store will also accept apps that are 64-bit only. This allows developers to limit deployment of an app to more recent devices with faster CPUs and GPUs. The device summary now has a line showing where 32-bit ends and 64-bit begins.

Finally, devices for testing:

  • At $199, the 16 GB, 5th generation iPod touch is still the most affordable compact iOS 9 device
  • At $299, the 16 GB, WiFi iPad mini 2 is now the most affordable iOS 9 iPad
  • As of 6/19/15, the original iPad mini is discontinued—try used and refurbished devices for low-end iPad testing.

iOS Device Summary: iPad Air 2 and iPad mini 3 Update

It’s been a busy few weeks with Apple announcements and Backtrace, our new album of iOS and Mac development songs, hitting the Billboard charts. I’ve updated my iOS Device Summary to include the recently announced iPads.

Check out the iOS Device Summary page for the rationale behind the summary as well as PDF downloads—including optimized files for printing.

The new iOS devices introduced this fall presented some challenges for the summary chart:

The iPad mini 2 and iPad mini 3 have identical processors and screens. The devices appear on the chart as a single entry, split to reflect the different supported OS versions.

We have not seen a revised iPod touch in two years. With the traditional Apple fall events behind us, it is unlikely we will see a significant update until next fall at the earliest. Since the iPod touch line ends at the A5 chip and the multiple-model iPhones start at the A6 chip, these have been combined into a single row.

Finally, the new A8X chip pushes the number of columns to the limit, so I’ve dropped the ARM chip and the iPhone 3GS and 3rd Generation iPod touch from the chart.

Since the chart is starting to have trouble cleanly representing devices on a single page, I am looking at more dynamic ways of presenting this information in the future.

Until then, I hope you find this version of the summary chart helpful. •

iOS Device Summary: iPhone 6 Update

I’ve updated my iOS Device Summary to include the new iPhone 6 models.

Check out the iOS Device Summary page for the rationale behind the summary as well as PDF downloads—including optimized files for printing.

At $199, the 16 GB 5th generation iPod touch is still the most affordable compact iOS 8 device.  It allows you to test on the slowest processor supported by iOS 8, with a screen resolution shared by the iPhone 5, iPhone 5c, and iPhone 5s. There is, however, no iPod touch that provides a less expensive way of testing the new screen resolutions on a device.

Of the two new iPhone 6 models, the iPhone 6 Plus seems to be the more important device to have on hand for testing, with both a new scale factor and a greater likelihood of providing a modified user interface to take advantage of all that lovely screen real estate. •

iOS Device Summary: iOS 8 Update

I’ve updated my iOS Device Summary for iOS 8 with the info Apple has publicly posted.

Check out the iOS Device Summary page for the rationale behind the summary plus PDF downloads—including optimized files for printing.

A few things to note:
  • The iPhone 4 is the only device that supports iOS 7 that will not support iOS 8
  • At $199, the 16 GB, 5th generation iPod touch is the most affordable compact iOS 8 device
  • At $299, the 16 GB, WiFi iPad mini is the most affordable iOS iPad

Important Points for Developers from Fall Apple Events

Chart showing iPhone CPU performance—with a large delta between the new iPhone 5s and the still-supported iPhone 4.Some of the most important points for developers to consider from the recent iPhone and iPad launch events are circled on these charts.

The charts show that the new A7 chip provides a significant boost in CPU and GPU performance.

But the charts show something else—the widest range in performance across supported devices of any iOS release, ever.

Chart showing iPhone GPU performance—with a large delta between the new iPhone 5s and the still-supported iPhone 4.

That giant difference in performance means it is more important than ever to test on lower-end hardware, to ensure the performance of your app is acceptable on older devices.

For iPhone apps, that means testing on an iPhone 4.  Recent analytics data from Localytics pegs global iPhone 4 share at 20.2% of all iPhones—a significant number of active users. If you don’t already have one for testing, you can pick up a used iPhone 4 on eBay with prices in the $150 – $200 range.
Chart showing iPad CPU performance—with a large delta between the new iPad Air and the still-supported iPad 2.

For iPad apps, there are two varieties of low-end config— those with and without Retina displays.

The iPad 2 and original iPad mini both use the A5 chip and have non-Retina screen resolution. Both are also still part of the current iPad lineup, making it all the more important to make sure your app performs well on these devices.

The second variety is the iPad (3rd Generation). As the first iPad with a Retina display, this model provides the baseline of performance for Retina display iPads.

Localytics data from last year shows the 3rd Gen iPad with 31% share when it was discontinued. That equates to millions of units still in the hands of customers.   If you need one for testing, used models are currently available on eBay for about $300 – $400.

Chart showing iPad GPU performance—with a large delta between the new iPad Air and the still-supported iPad 2.With such a large spread in performance among devices that support iOS 7, testing on the lower end of the performance spectrum has never been more important. •
