One of the reasons Apple says you shouldn’t jailbreak your iPhone is because doing so will impact performance. But is that actually true, or is that just what Apple wants you to believe? This video holds the answers.

In the video, created by iAppleBytes, two 16GB iPhone 5’s running iOS 9.0.2 are compared. The only difference? One is jailbroken using the latest Pangu exploit, the other isn’t.

So how’d they do? The unjailbroken iPhone 5 booted up in 38.8 seconds, compared to 51.2 seconds for the modded phone. Launching an app for the first time, entering multitasking or invoking Siri also gives the unjailbroken device the slight advantage, although not to the same extent as in the boot-up test.

The takeaway? There’s a marginal performance hit for jailbreaking your iPhone. It’s mostly apparent in booting up your iPhone after powering down completely, but there’ll be a slight performance impact in pretty much every task. Whether that trade-off is worth it to you in exchange for advanced features and tweakability is up to you.
