What is the hardest phone to repair? A Tech Pro's Top 3 Challenges

As a tech professional with over 15 years of experience at iFix, a top repair company, I’ve seen some intricate phone repairs. Whether it's a cracked screen or a faulty battery, the difficulty level can differ widely from one model to another. Today, I want to share what I believe are the top three hardest phones to repair, drawing from my extensive hands-on experience. So grab your tools and let’s explore the world of tough phone repairs!

Understanding Phone Repair Complexity


Before we jump into the specific models, it’s essential to grasp what makes a phone repair intricate. Several factors contribute to this complexity:


  • Adhesive Type: The kind of adhesive used can make screen removal a significant challenge. For example, some manufacturers use ultra-strong glues that require heat.

  • Tight Internal Layout: A compact design means parts are closely packed, which complicates access.

  • Accessibility: Some phones are designed with repair in mind, while others are not, making some tasks almost impossible for the average person.


Models with high repair difficulty demand specialized tools and often result in longer repair times. Over the years, I’ve learned that while some companies prioritize sleek designs, it often compromises repairability.


Difficult internal components

1. iPhone 12 and 13 Series


The iPhone 12 and 13 series are among the most challenging phones to repair, with difficulty levels that often leave even experienced technicians scratching their heads. From the moment you open the case, you’re greeted by a maze of screws and parts.


  • Technical Tightness: These models have a densely organized internal layout which makes accessing crucial components like the battery a daunting task. The adhesive is exceptionally strong, often requiring specialized heating pads and careful techniques to avoid damage.


  • Battery Replacement Challenge: A notable hurdle is replacing the battery. The strong adhesive complicates the process, but the real kicker is the Face ID mechanism. If the front panel is incorrectly removed, you risk disabling Face ID permanently. This added layer of complexity solidifies the iPhone 12 and 13 series as some of the hardest to fix.


According to a 2022 repairability score from iFixit, these devices received a low score of 6/10, reflecting their challenging repairability.


2. Samsung Galaxy S21 Ultra


The Samsung Galaxy S21 Ultra is another strong contender for the title of hardest phone to repair. It’s laden with cutting-edge features, but that comes with a range of repair hurdles.


  • Advanced Adhesive: Like the iPhone, the Galaxy S21 Ultra employs strong adhesive that requires heat for screen removal. The added challenge of its curved display heightens the difficulty, risking damage to the delicate edges during repairs.


  • Camera Array Complexity: This model is packed with an impressive camera system that contains four lenses tightly fitted into a small area. If one camera gets damaged during repairs, it can impact the entire system. The interconnectivity of these components means that even small missteps can lead to significant issues.


The repairability score for the S21 Ultra is even lower, sitting at 3/10, highlighting its non-repair-friendly design elements.


3. Google Pixel 5


Surprisingly, the Google Pixel 5 ranks among the most challenging phones to repair, mainly due to its unusual design choices.


  • Unusual Construction: Unlike its counterparts, the Pixel 5 uses a material that is not only tough to open but can also be easily damaged during repair. The back panel, made of an aluminum composite, is notably different, presenting unique challenges to tech enthusiasts used to glass or plastic.


  • Water Resistance Issues: Its IP68 rating indicates strong water resistance. However, this means that opening the Pixel 5 can compromise its waterproof capabilities. If moisture enters the device during a repair, you may need to replace the entire phone instead of just addressing a cracked screen.


For reference, the Pixel 5 received a repairability score of 6/10, indicating it is somewhat manageable but still has significant challenges.


Wrapping Up


The landscape of phone repairs is filled with hurdles, but the iPhone 12 and 13 series, Samsung Galaxy S21 Ultra, and Google Pixel 5 stand out as the most challenging. From robust adhesives to easily damaged features, each device brings its set of obstacles that demand skill and patience.


As a tech enthusiast, I encourage others interested in phone repairs to explore these complex models. Gaining insights into these repair challenges enriches your understanding and prepares you for the unexpected.


Whether you’re a DIY enthusiast or just curious, knowing about these complicated phones can be incredibly helpful in your repair journey. Always remember that every repair is an opportunity to learn!
