iOS 8.3 Jailbreak on iPhone 6 Impressions & Performance



An iOS 8.3 jailbreak was released last week. Here’s how it performs on the iPhone 6.

For the first time in several months, iPhone and iPad users have been graced with a new jailbreak. This time around, it works with iOS 8.3, which has ton of new improvements over iOS 8.1.2, which was the last version of iOS that was jailbreakable.

The iOS 8.1 jailbreak was released back in December of last year, so it’s safe to say that it’s been a long time since we’ve seen a new jailbreak, and those stuck on iOS 8.1 have certainly been missing the new features and improvements that iOS 8.3 had to offer.

Luckily, jailbreakers no longer need to stay on iOS 8.1, as they can now update to iOS 8.3 and jailbreak their devices.

I ended up jailbreaking both my iPhone 6 and my iPad mini 2 when the iOS 8.3 jailbreak came out, and I’ve taken some time to see how well the iPhone 6 performs compared to when it was running iOS 8.1.2. There are a few things with the jailbreak that still need worked out, but I found performance to be really good overall.


Keep on reading for a more detailed look into the iOS 8.3 jailbreak and how it performs on the iPhone 6.

First Impressions

First impressions are usually a bit superficial with jailbreaks, mostly because if you notice Cydia works and you can install tweaks just fine, then it’s a good jailbreak. Of course, though, it goes a bit deeper than that.

The iOS 8.3 jailbreak tool from TaiG is really easy to use and takes just a few minutes to jailbreak your device. You have to make sure to uncheck “3K Assistant” before you start the process, but other than that it’s smooth sailing.


When the tool first released, the jailbreak didn’t support Cydia yet, so there were a few days when users could jailbreak their iOS 8.3 device, but were unable to use any jailbreak tweaks. Thankfully, that got fixed later in the week, and it’s now a fully working iOS 8.3 jailbreak.

One thing that I have noticed way more in the iOS 8.3 jailbreak (as opposed to when I was on the iOS 8.1.2 jailbreak) is that my WiFi and LTE don’t seem to crap out anymore. Usually every other day I wasn’t able to access the internet at all on my iPhone 6 and I would need to restart it. However, after being on the iOS 8.3 jailbreak for about five days now, I haven’t come across this problem once.


Most of the performance improvements that I’ve been noticing with the iOS 8.3 jailbreak are mostly because of iOS 8.3 itself and not necessarily just because of the new jailbreak, but I have noticed that Cydia performs a bit better this time around, and it’s an overall more stable jailbreak than before — no weird things happening with iOS because of the jailbreak, and no random reboots like I used to experience with iOS 8.1.

I have noticed that battery life is a lot better on iOS 8.3, even with the jailbreak. My battery will only go down to about 80% at the end of the day, compared to 50 or 60% most of the time when I was on iOS 8.1.

I’ve also noticed that Touch ID is a lot more responsive. It scans my finger way more quickly than before, and the number of times that it says it can’t read my fingerprint has gone down quite a bit. Overall, I feel that Touch ID is finally in a place where it works like it’s supposed to, whereas before I would find myself just using the traditional passcode more and more so that I wouldn’t have to bother with Touch ID.

The only big downside with the iOS 8.3 jailbreak is that there are still some big jailbreak tweaks that need to be updated, as they don’t currently work with the iOS 8.3 jailbreak just yet. Some notable tweaks that come to mind are Springtomize and BiteSMS. I use a lot of the features in Springtomize, and since it lets you do some much with your iPhone, it’s the one jailbreak tweak that I’m missing the most right now.

However, once Springtomize and other big jailbreak tweaks are finally updated, I think the iOS 8.3 jailbreak will be at a perfect place. It’s admirable right now, but there’s nothing wrong with sticking with iOS 8.1.2 until many of the bigger tweaks that you might use are fully updated to support iOS 8.3.
