High End HTC One M8 Scores Low Marks For Do-It-Yourself Repairs
Like its predecessor, the HTC One M8 isn't a repair-friendly device. Getting it open requires heating up the adhesive to soften the glue, and then prying off the speaker grill with a thin object like a guitar pick. There are screws underneath, and once removed, the handset separates into two parts.
Unfortunately, that's where Easy St. comes to a dead end. Things quickly turn "ugly" when diving any deeper into the One M8, which is littered with tape, tape, and more tape. Your reward for getting past all that tape is a series of 10 cables that need to be disconnected so that you can focus on the glued down motherboard.
Why would anyone need to gut a smartphone like that? To be fair, most people won't. However, it's the only way to get to the 'non-removable' battery, which could come into play if the handset is out of its warranty period. Non-removable batteries aren't always easy to get to, but they're usually not buried underneath a glued-down motherboard, either.
When all was said and done, iFixIt gave the HTC One M8 a 2 out of 10 Repairability Score, which is one point higher than the original One. That's not a deal killer for anyone considering the One M8, but something to keep in mind if you like to tinker with your gadgets.
