The beta version of iOS 9 will be widely available to users this July, and it's highly likely that the official iOS 9 version will be launched in September this year. The devices eligible for iOS 9 update include: iPad 2, iPad 3, iPad 4, iPad Air, iPad mini, iPhone 4S, iPhone 5, iPhone 5C, iPhone 6, iPad 6 Plus, and iPad Touch 5.
iOS 9, like iOS 8, focuses on improving performance instead of changing the interface like iOS 7. However, iOS 9 still brings many anticipated features such as split-screen multitasking on iPad and the new Apple News reading app.
Your question, whether to update iOS 9 for iPhone 4s, iPhone 5, will be divided into 2 scenarios:
- If you want to experience iOS 9:
For the purpose of experiencing new features, upgrade your device using a developer account or manually download the firmware and then upgrade through iTunes.
+ Regarding iPhone 4S, although it's quite an old device from Apple, it's still included in the update list. You will still be able to update successfully, but the experience may not be as smooth. So, consider carefully before updating.
+ Similarly for iPhone 5, it's just slightly better than iPhone 4S.
+ Siri on iOS 9 is smarter and has a 40% more accurate task execution compared to the previous version. Additionally, it can also track your mailbox, calendar, and notes more comprehensively.
- If you need stability ?
If you require stable performance, then at this time, you should use iOS 8.3 instead of hastily upgrading to iOS 9. The activation process may encounter some issues, so when you successfully upgrade to iOS 9 for iPhone 4S or iPhone 5, you will have to switch to using iCloud only for synchronization and backup tasks.
+ Moreover, updating to iOS 9 unofficially may lead to certain risks.
+ Currently, not all the issues with iOS 9 are known. You might encounter some unresolved bugs, and the only solution may be to revert back to iOS 8. So, wait for some more time to gather complete information about iOS 9 before updating if you want to upgrade for iPhone 4s and iPhone 5.
Through this article, we want to advise users, especially owners of iPhone 4S and iPhone 5, that if you want to experience the new features of iOS 9, you can proceed with the update as usual. However, if you prioritize stability, stick with iOS 8.
