Yes—Apple lists the iPhone 11 and iPhone SE (2nd and 3rd generations) as compatible with iOS 27. If you own one, check the update offered for your specific phone at Settings > General > Software Update, back up first, and remember that Apple says an installed iOS update cannot be downgraded. Compatibility does not guarantee that every iOS 27 feature is available on every model.
Which iPhone 11 and iPhone SE models support iOS 27?
Apple’s compatibility guide names the iPhone 11, iPhone SE (2nd generation), and iPhone SE (3rd generation) as compatible with iOS 27. The first-generation iPhone SE is not named on that list, so “iPhone SE” alone is not enough to determine compatibility. Apple’s iOS 27 compatibility guide also directs owners to the phone’s Software Update screen to see the latest iOS compatible with their model.
Should you install iOS 27?
If your phone is one of the listed models, Apple’s compatibility list supports proceeding with the update offered for that device. Before installing, make a backup and confirm the version on the phone itself. Apple recommends backing up before an update and says the download instructions show only updates compatible with the device. If the phone is running an earlier version, Apple instructs users to install that version first. See Apple’s iOS 27 download instructions.
- Identify the exact model. For an SE, confirm whether it is the 2nd or 3rd generation; the compatibility listing does not name the 1st-generation SE.
- Back up the iPhone. Apple recommends making a backup before updating.
- Check the offered update. Open Settings > General > Software Update. The screen shows the latest iOS compatible with that phone.
- Install the offered version. If Apple presents an earlier version first, follow its instruction to install that version before proceeding.
What version is current, and can you go back?
As of Apple’s security-releases listing checked on October 7, 2026, the latest release listed was iOS 27.0.1, dated September 28, 2026. That is a dated release listing, not a guarantee that it remains the latest version; check Software Update for what is currently available to your model. Apple says an iOS update cannot be downgraded to the previous version once installed. Apple’s security releases page labels the iOS 27.0.1 entry “This update has no published CVE entries.” That wording describes the listing’s published CVE entries; it does not establish that the update contains no changes or that it has no security relevance.

Will iOS 27 slow down an iPhone 11 or iPhone SE?
Apple’s cited compatibility, preparation, and release information does not report comparative speed, battery life, or reliability results for iOS 27 on these phones. It therefore does not support a claim that the update will make an iPhone faster or slower, or predict how its battery will perform. Apple does caution that features and apps may differ by model, region, language, and carrier. As Apple puts it, “Your features and apps may vary depending on your iPhone model, region, language, and carrier.” Check any particular feature you rely on separately rather than assuming every listed model has feature parity.
