The newiPhone 14 has delivered a few new high-profile features, such as the emergency satellite message feature and the Dynamic Island. But perhaps one of the most intriguing updates is one that's not visible on the outside. 

According to device-repair expert and 'right to repair' advocate iFixit, a closer look at the iPhone 14 shows it has actually been through a major internal redesign that makes it significantly easier to repair than its predecessors.

As such, iFixit has given the iPhone 14 a repairability score of seven out of 10 -- the iPhone's best score since the iPhone 7.

So, what's changed? The back panel can now be easily removed by repairers in addition to the screen, meaning the device can be opened from the front and back.           

As iFixit CEO Kyle Wiens details in a blogpost, the back glass is secured with just "two screws and a single connector" that give repairers access to both the screen and back glass. Also, Apple appears to have used a "slightly less aggressive adhesive, making opening it up a tad easier than screens of yore."

The ability to remove both the screen and the back panel addresses one of the key repairability challenges with the iPhone. Since the iPhone 5, Apple has made the back optimized for battery and screen replacements, iFixit explains in a YouTube teardown demo. 

"This advantage of the front optimized design of course is that it's harder to replace the back glass panel. This new design solves that problem but it wasn't easy. Achieving the high levels of durability that we've all come to expect, including drop resistance and torsional rigidity, is an incredible engineering challenge."

The more easily replaceable glass back panel is a big deal. As iFixit explains in its iPhone 11 and 11 Pro Max repairability scores, if the back glass breaks on those models, you need to remove every component and replace the entire chassis.

iFixit rightly asks why Apple didn't announce iPhone 14's improved repairability. After all, Apple recently announced its Self Service Repair program, which offers people repair manuals and genuine Apple parts and tools to fix their iPhones and Macs. (Apple has yet to release manuals and components for the iPhone 14 line.)

iFixit does note one downside to Apple's repairability improvements for the iPhone 14's back panel. After installing a replaced back glass, Apple might require software-based activation.    

"We are hearing reports that Apple is continuing their hostile path of pairing parts to the phone, requiring activation of the back glass after installation. You really shouldn't need Apple's permission to install a sheet of glass on a phone that you already own," writes iFixit's Wiens. 

"Using software to prevent the use of aftermarket parts gets a big thumbs down from us. These locks are frustrating and ultimately futile -Apple simply can't control all the repairs that happen with their products, no matter how hard they try. We'll be reporting on parts compatibility a bit more after we finish our lab tests, unless Apple miraculously posts their service manuals."

Nonetheless, iFixit calls the iPhone the "most substantial iPhone redesign since the 10".
