Apple’s new phone gets a very reasonable 7 out of 10 repairability rating, scoring just above last year’s iPhone 4S, which earned a 6 out of 10. But for home repair aficionados, there are still a number of integrated components that can make repair costs add up quickly.

 Unsurprisingly, Apple still uses those fancy pentalobe screws to keep the iPhone’s exterior intact. But once those are removed, the display portion is easily accessible, and more so than on the iPhone 4 or 4S. This is welcome news for the DIY-minded — not to mention the clumsy among us, since shattered display glass is one of the most common iPhone injuries. However, the front glass, digitizer, and LCD are combined into a single unit, so screen replacement will still be costly.

After taking the screen off, the iFixit team consulted a high-precision scale and found the weight difference between the 4S and 5 to be stunning.

“The entire rear case of the iPhone 5 weighs only slightly more than just the glass rear panel of the 4S,” they say.
