How to get your iPhone ready for the iOS 27 update
Apple is preparing to release iOS 27, and users are advised to take several steps beforehand to ensure a smooth update. Key recommendations include freeing up storage, charging the device, and backing up data.
As Apple prepares to roll out iOS 27, users are being advised to complete a few preparatory steps to avoid problems during installation.
Storage and battery
The update process needs space not only for the installation itself but also for temporary files, so it's recommended to have roughly 18 to 25GB of free storage available. If an iPhone is running low on space, unconventional cleanup methods may be needed. Having enough battery charge is also important — while 50 percent should technically be sufficient, it's safer to keep the device plugged in throughout the update. Staying connected to Wi-Fi is recommended as well.
Automatic versus manual installation
Users can choose whether to install the update themselves or let it happen automatically, a setting found under Settings > General > Software Update > Automatic Updates. Choosing automatic installation means iOS 27 won't install the moment it becomes available — instead, it will update overnight while charging and connected to Wi-Fi, with a notification possibly arriving days or weeks later. Those who prefer to control the timing should check the Software Update page directly. It's also worth first installing iOS 26.6, which includes an indexing update meant to smooth the transition to iOS 27's changes to Siri.
Don't skip the backup
Backing up a device before a major update like iOS 27 is essential, since such updates can occasionally cause data loss. This can be done via iCloud by going to Settings > Apple Account > iCloud > iCloud Backup > Back Up Now, or by backing up to a Mac or Windows computer instead. Users should also keep their Apple ID credentials on hand to avoid being locked out if anything goes wrong during the process.
The headline feature of iOS 27 is a redesigned Siri app, part of Apple's effort to catch up with rivals like Gemini and ChatGPT. The update is also expected to bring a cleaner, more readable design, improved performance, new child safety features, and various tweaks across other built-in apps.
