Imagine your iPhone as a treasure chest filled with photos, messages, and games. Just like you wouldn't want your real treasure chest unlocked, you wouldn't want anyone accessing your personal information on your phone. Every year, Apple releases new versions of iOS, the operating system that runs iPhones. These updates are like upgrades to your phone's security system, making it more robust and reliable. But with so many versions, which is best for keeping your iPhone safe? Let's explore!

A World of iOS Versions

Apple releases a new iOS version every year, usually in September. Each version comes with new features, improvements, and security updates. Using the latest or a recent reliable version of iOS is crucial to keep your iPhone safe from hackers and other online dangers.

Key Features in iOS

Several features within iOS work together to keep your iPhone safe:

  • Encryption and Data Protection: Imagine your data being locked away in a secret code. Encryption scrambles the information on your iPhone, making it unreadable to anyone who shouldn't see it.
  • App Permissions and Privacy Settings: Think of these as permissions you give apps to access certain things on your phone, like your location or camera. iOS lets you control these permissions and choose what information apps can access.
  • Security Updates and Patches: Just like mending a hole in your clothes, security updates fix weaknesses in the iPhone's security system. These updates are regularly released to address new threats and protect your phone.

Fast and Reliable:

Security is essential, but you also want your iPhone to run smoothly. Here's how different iOS versions compare in terms of performance:

  • Speed and Efficiency: Newer versions of iOS are often optimized to run faster and use less battery than older ones.
  • Stability and Bug Fixes: Updates often fix bugs (小さな問題, chiisai mondai - minor problems) that can cause crashes or glitches on your phone.
  • Compatibility with Older Devices: Sometimes, newer iOS versions might not be compatible with very old iPhones, meaning they might not run smoothly or install.

Comparing Top Contenders

Let's see how some recent iOS versions stack up in terms of security and performance:

  • iOS 14 (2020):
  • New Features and Improvements: Introduced widgets on the home screen, improved privacy settings with app tracking controls, and added security features like restricting USB access when your iPhone is locked.
  • Security and Reliability Ratings: Generally received high marks for security updates and user privacy features. Some users reported occasional bugs in the initial release, which were addressed later.

  • iOS 13 (2019):
  • Features and Updates: Brought a significant redesign with a new dark mode, improved Siri (Apple's virtual assistant), and introduced new photo and video editing tools.
  • Performance and Reliability Analysis: While offering exciting features, iOS 13 experienced some initial performance issues and battery drain problems for some users. Later updates improved stability.

  • iOS 12 (2018):
  • Longevity and Support: iOS 12 was known for its focus on performance and stability, particularly for older iPhones.
  • Comparison with Newer Versions: While offering good security, iOS 12 lacked some of the advanced privacy features introduced in later versions like iOS 14.

What Users Say:

User feedback is valuable when choosing an iOS version. Here's what people generally say:

  • Surveys and Polls: Surveys often show user satisfaction increasing with newer iOS versions due to the addition of new features and security updates.
  • Common Issues and Complaints: Some users may encounter compatibility problems while updating to a new iOS version on older devices. Performance glitches can also occur in the initial releases of new versions, but these are usually addressed in later updates.
  • Overall User Satisfaction Ratings: Generally, users appreciate the improved security and privacy features in newer iOS versions. However, some might prefer the stability and performance of older versions, especially for older iPhones.


There's no single "best" iOS version for everyone. Here's a guide to help you choose:

  • Prioritize Security: Choose the latest or a recent reliable iOS version (like iOS 14 or 15) to benefit from the strong security features and latest updates.
  • Balance is Key: If you have an older iPhone and prioritize stability, consider a slightly older, well-supported version like iOS 12 or 13 that still offers good security while maintaining smooth performance.
  • Future-Proofing: Selecting a recent version of iOS can provide you piece of mind for the future because newer versions are often supported with security patches for longer.

The Future of iPhone Security

Apple is continuously working to improve the security and performance of iOS. Here's what to expect:

  • Enhanced Security Features: Expect features like improved app sandboxing (restricting app access to other parts of your phone) and even more granular control over app permissions.
  • Focus on Privacy: Apple will continue prioritizing user privacy with features that give you more control over your data.
  • Performance Optimization: Apple will strive to optimize future iOS versions to run smoothly and efficiently on all compatible iPhones, including older models.
