Installing the first iOS 27 beta on a 2019 iPhone 11 Pro Max made everyday tasks measurably faster than on iOS 26, according to stopwatch tests published by the source author. Apple Maps went from 3.01 seconds to 1.36 seconds to load, the Camera app launched in about 0.65 seconds instead of 0.98, and Safari, the App Store, and the Share sheet also opened more quickly. The author also reports smoother animations and a cooler phone body. These are one person’s measurements on a single device running beta software, so results may vary and could change in later builds.
What you need to know
- On the same iPhone 11 Pro Max, Apple Maps loaded in 1.36 s on the iOS 27 beta versus 3.01 s on iOS 26, more than twice as fast.
- Camera launch dropped from 0.98 s to about 0.65 s, and taking a photo and opening it from the preview fell from 3.61 s to 2.44 s.
- The author reports smoother Control Center swipes, faster unlocking, and a body that stays cool for longer, though the software is still a beta.
- The iPhone 11 Pro Max does not get the AI-powered Siri, but it does receive features such as custom Wallet cards, a keyboard clipboard button, separate alarm/timer volume, and a Liquid Glass transparency slider.
iOS 27 noticeably speeds up older iPhones
The test device: a six-year-old iPhone 11 Pro Max on iOS 26
The source author obtained the phone from an acquaintance who had moved to a newer model and was about to trade it in. The iPhone 11 Pro Max dates from 2019 and was described as being in good working condition. It was running iOS 26, and the author says the slowdown was immediately obvious: animations stuttered, apps opened with a delay, and the Liquid Glass interface was clearly a strain on the older hardware.
On iOS 26 the phone clearly struggled
The author notes that the iOS 27 presentation at WWDC centered on an AI-powered Siri and other Apple Intelligence features that only work on newer models, leaving owners of older iPhones wondering whether they would get anything beyond bug fixes. That, the author says, was the reason for a healthy dose of skepticism going in.
After the update, the iPhone 11 Pro Max was a pleasant surprise
According to the source, Apple said iOS 27 would address performance problems. Rather than take that on faith, the author installed the beta on the old device and compared it with iOS 26. The author stresses that this is still beta software, but says the difference was already noticeable, and for the better.
Stopwatch results: iOS 26 versus iOS 27 on the same phone
To avoid relying on impressions alone, the author timed several everyday tasks on the same iPhone 11 Pro Max, first on iOS 26 and then on iOS 27. The tests covered things people do many times a day: the camera, maps, and the browser. Each action was repeated several times and averaged so that a random background process would not skew the result.
The camera came first, since missing a shot because of lag is the most frustrating failure. On iOS 26 the Camera app opened in 0.98 seconds, and taking a photo and having it saved to the gallery took 3.61 seconds. On iOS 27 the camera launched in roughly 0.65 seconds, and the photo was ready and opened from the preview in 2.44 seconds.
Apple Maps showed the largest gap. On iOS 26 the app took a full 3.01 seconds to load; on the first iOS 27 beta it opened in 1.36 seconds, more than twice as fast. The full set of measurements:
| Task | iOS 26 | iOS 27 (beta) |
|---|---|---|
| Launch Camera app | 0.98 s | 0.65 s |
| Take photo and save to gallery | 3.61 s | 2.44 s |
| Launch Safari | 1.88 s | 1.21 s |
| Open Share sheet | 1.05 s | 0.96 s |
| Load Apple Maps | 3.01 s | 1.36 s |
| Launch App Store | 3.46 s | 2.68 s |
Safari, the App Store, and the Share sheet also opened noticeably faster. Individually, the gains are fractions of a second, but the author argues that repeated dozens of times a day they add up to minutes, and the system as a whole feels more responsive.
Smoother animations and a cooler body
The raw numbers are only part of the picture. The author says the bigger change is that the interface on the iPhone 11 Pro Max simply became more pleasant to use day to day.

The swipe to open Control Center is described as noticeably smoother, unlocking is faster, transitions between apps rarely stutter, and the frame rate no longer dips in places where it was obvious on iOS 26. Each is a small thing, but together the author says they create the impression that the old hardware is no longer straining to run the system, and that Apple appears to have cleaned up almost all of the problematic animations.
Temperature was another pleasant surprise. On iOS 26 the phone heated up easily, even on simple tasks; on iOS 27 the body stays cool for noticeably longer. The author interprets a cooler phone as a sign that background processes are not churning needlessly, which usually goes hand in hand with gentler battery consumption. However, the author explicitly cautions that this is a beta and that load on the hardware will fluctuate over the test cycle, so no firm battery conclusions are offered.
What else older iPhones get in iOS 27
After the keynote it might have seemed that older iPhones would receive little more than bug fixes. According to the source, that is not the case. The iPhone 11 Pro Max will indeed not get the AI-powered Siri, but the list of other additions is substantial. Wallet, for example, now lets users create their own cards, which the author used to add plastic cards and stop carrying a physical wallet.
The author’s personal favorite is a new clipboard button directly on the keyboard, which makes pasting text or a freshly taken screenshot noticeably quicker. The ability to set alarm and timer volume separately also earned praise.
Pasting has become far more convenient
Other smaller conveniences listed in the source include a redesigned interface for listening to audio messages in iMessage, the ability to save a high-resolution frame from a video in Photos, and larger Home Screen widgets. In addition, all iPhones on iOS 27 get a refined Liquid Glass design with a new transparency slider for adjusting the look to taste.
The iPhone 11 Pro Max certainly did not catch up with the iPhone 17 Pro Max in speed, but it improved significantly
The bottom line, and the caveats
In the author’s assessment, the aging iPhone 11 Pro Max runs faster on iOS 27, animations are smoother, the body stays cooler, and the update brings a handful of genuinely useful features. For a device many owners had mentally written off, that is a strong result, and the author suggests that older models may turn out to be the biggest winners of this release even though the public attention is focused on AI. The lack of the AI Siri on the iPhone 11, the author argues, is not worth worrying about.
Keep the limitations in mind, though. These figures come from a single phone, timed by hand by one person, on the first beta of iOS 27. Beta builds change from release to release, performance and thermal behavior can shift as the software matures, and the source does not report battery-life measurements. Anyone considering installing a beta on an older daily-use device should weigh the usual risks of pre-release software.
