If you own an older iPhone, a question arises when Apple releases a new version of the iOS: Should you upgrade? Everyone wants to get the latest and greatest features of a new OS, but if you've got an older phone, new features sometimes need more power to work well than your phone offers.

This is the scenario facing owners of the iPhone 4. Should they install iOS 7? To help you make an informed decision, I've compiled the reasons for and against upgrading an iPhone 4 to iOS 7.

Reasons to Upgrade iPhone 4 to iOS 7

Here are some of the reasons in favor of upgrading to iOS 7:

  • No more OS upgrades. iOS 7 is the last version of the iOS that runs on the iPhone 4, so you won't be able to upgrade to 8, 9, or beyond. If you want to really max out the capabilities of your iPhone 4, iOS 7 is the way to do it.
  • iOS 7.1 is tuned for iPhone 4. The 7.0 release received a lot of complaints from iPhone 4 owners who said that it bogged their phones down so much that they were almost unusable. Apple heard those complaints and addressed them in iOS 7.1, which runs substantially faster on the iPhone 4
  • Key new features. iOS 7 introduced some major new features to the iPhone that we now take for granted. Do you really want to skip features like Activation Lock, Control Center, iCloud Keychain, and the new design and interface? To get them, you need iOS 7.
  • Bug fixes. Every new iOS release fixes bugs and security issues. If you upgrade, your iPhone won't be exposed to problems or potential attack that could be protected against.

Reasons NOT to Upgrade iPhone 4 to iOS 7

The arguments against upgrading include: 

  • Performance problems. The iPhone 4 is the oldest device that iOS 7 can be installed on. The iPhone 4 is so old at this point that hasn't sold it for years, so it's far from the latest, greatest, or fastest iPhone on the market. It's got a slower processor, less memory, and a smaller battery than the newer models.
  • Missing features. Because the iPhone 4's hardware is older, there is a number of cool iOS 7 features that don't work on it. These include Panoramic photos, AirDrop, Siri, Traffic information in Notification Center, and Filters in the Camera app.
  • You can't downgrade. If you upgrade to iOS 7 and find you don't like it, you can't downgrade your phone to iOS 6 again
  • There are better upgrades. Why waste time upgrading your OS when you could upgrade to a new phone for little or no money? Check out the end of the article for more information on new phones.

The Bottom Line: Should You Upgrade?

Whether you upgrade your iPhone 4 to iOS 7 is up to you, of course, but I'd be cautious. If you upgrade, you'll be putting the latest OS, which requires a lot of processing horsepower and memory, onto a device that's approaching the end of its usable life. The combination will work, but it may be slower or more problematic than you'd like.

If you're willing to live with some bugs or slowness and just have to have the latest OS, go for it. Otherwise, I'd hold off.

A Better Upgrade: A New Phone

The iPhone 4 was released way back in 2011. In terms of modern consumer technology, that's ancient. New phones are much faster, have bigger screens, can store much more data, and have better cameras. Other than the cost, there's really no reason to continue to use an iPhone 4 at this point.

Consider upgrading to a new iPhone instead. That gives you the best of both worlds: you'll get a fresh, fast new phone with all the latest hardware features and the latest version of the iOS. I'd much rather pay for those new things than have a poor experience on an old phone.

The latest models, the iPhone 8 and iPhone X, have a lot of great features. ​If you're looking to spend less money, the iPhone 7 (read review) is still available for lower prices. I always recommend buying the newest and best phone you can afford since it will last the longest. Still, any model you upgrade to from the iPhone 4 will be a major improvement.
