The team actually gave the HTC One M9 the same score as the M8 (an abysmal 2 out of 10), which proved to be just as difficult to repair. This shouldn't come as much of a surprise considering we're looking at a similar design with the two handsets. Some highlights from the teardown include notable defects with the unit iFixit received, including a dead pixel on the screen as well as some minor scratches.
The HTC One M9 was – however – fairly easy to take apart initially, not requiring heat for the case to be taken apart. But this was soon forgotten by intense use of adhesives, making numerous components difficult to both remove and replace. Another major drawback for phone repairability is actually the battery. Just like the M8, the HTC One M9's battery is buried deep inside the device, hindering its replacement.
