Honor launched the Robot Phone in China in August, and today it’s reached Zack from the JerryRigEverything YouTube channel. Unsurprisingly, he’s subjected it to his usual battery of “durability tests”, and then disassembled it – all in the video below, so grab some popcorn and enjoy the ride.
Durability Test Overview
Zack’s durability tests are legendary for pushing smartphones to their absolute limits. The Honor Robot Phone, with its unique gimbal camera system, presented a particularly intriguing subject for these trials. Would the mechanical components survive the infamous scratch, burn, and bend tests? The answer, as it turns out, is a mixed bag of impressive resilience and surprising vulnerabilities.
Scratch Test Results
The scratch test is always the first order of business. Using Mohs scale picks, Zack begins scratching the display. The Honor Robot Phone’s front glass scratches at level 6, with deeper grooves appearing at level 7. This is consistent with most modern flagship smartphones, which use similar glass compositions. The scratches are visible but not catastrophic, and the display continues to function normally. The metal frame of the phone also shows signs of scratching, but this is expected for any device with a metallic chassis. The gimbal camera module, however, is a different story. Its lens is protected by glass, but the surrounding housing is made of plastic, which scratches relatively easily. This could be a concern for users who frequently place their phone face-down on rough surfaces.
Burn Test Findings
The burn test involves holding a lighter flame against the display for an extended period. The Honor Robot Phone’s OLED panel behaves as expected, with the pixels turning white and eventually blackening under the intense heat. The damage is permanent, but it’s localized to the area directly exposed to the flame. This test is more about assessing the display’s resilience to accidental burns (like from a cigarette) rather than everyday durability. The phone survives, but with a permanent scar.
Bend Test and Structural Integrity
The bend test is where things get really interesting. Zack applies pressure to the back of the phone, attempting to bend it. The Honor Robot Phone holds up surprisingly well, resisting bending without any catastrophic failure. There’s a slight flex, but the phone doesn’t snap or crack. The gimbal camera, however, is a point of concern. When pressure is applied near the camera module, there’s a noticeable creaking sound. Upon closer inspection, Zack discovers that the gimbal mechanism is not as robustly mounted as one might hope. The camera can be moved slightly within its housing, which could lead to long-term reliability issues if the phone is subjected to repeated stress. Nevertheless, the phone survives the bend test without breaking, which is a testament to its overall build quality.
Teardown: Inside the Honor Robot Phone
After the durability tests, Zack proceeds to disassemble the Honor Robot Phone. This is where we get a glimpse of the engineering marvel (and potential compromises) that make this device unique. The teardown reveals a complex internal layout designed to accommodate the gimbal camera while maintaining a slim profile.
Removing the Back Panel
The first step is to remove the back glass panel. Zack applies heat to soften the adhesive and uses a suction cup and pry tool to separate the panel from the frame. Inside, we see a large graphite heat spreader covering the battery and mainboard area. This suggests that Honor has paid attention to thermal management, which is crucial given the additional heat generated by the gimbal motors.
Battery and Mainboard
The battery is a prominent component, occupying a significant portion of the internal space. It’s a dual-cell design, which allows for faster charging and more efficient power distribution. The mainboard is densely packed with chips, including the Qualcomm Snapdragon processor, RAM, and storage. The gimbal camera connects to the mainboard via a flexible ribbon cable, which also carries power and data signals. The camera module itself is a marvel of miniaturization, featuring a motorized gimbal that can rotate the lens in multiple axes.
Gimbal Camera Module
The gimbal camera is the star of the show. Zack carefully removes it from its housing to examine its construction. The module consists of a small image sensor, a lens assembly, and a set of tiny motors that drive the gimbal. The motors are surprisingly small, yet they provide enough torque to stabilize the camera during movement. The gimbal is mounted on a set of ball bearings, which allow for smooth rotation. However, Zack notes that the bearings are not sealed, which means dust and debris could potentially enter and cause jamming over time. This is a potential durability concern that Honor may need to address in future iterations.
Cooling System
Cooling is a critical aspect of any smartphone, especially one with moving parts. The Honor Robot Phone employs a vapor chamber cooling system, which is a step up from the graphite sheets found in many other phones. The vapor chamber is located directly beneath the mainboard and helps dissipate heat generated by the processor and the gimbal motors. During the burn test, the phone did get noticeably warm, but the cooling system seemed to manage the heat effectively. In the teardown, we can see the vapor chamber is quite large, covering a significant area of the internal chassis.
Speakers and Other Components
The teardown also reveals the phone’s bottom-firing speaker, USB-C port, and SIM tray. These components are fairly standard and appear to be well-protected against dust and water ingress. The phone has an IP54 rating for splash resistance, which means it can handle light rain but shouldn’t be submerged. The gimbal camera area, however, is a potential weak point for water resistance, as the moving parts create gaps that could allow moisture to enter. Honor has likely applied some form of sealing, but it’s not as robust as on a fully sealed phone.
Repairability Assessment
Zack’s teardown also serves as a repairability assessment. The Honor Robot Phone is not particularly easy to repair. The back panel is glued on, requiring heat and patience to remove. The battery is also glued in place, making replacement difficult. The gimbal camera, while modular, is complex and likely expensive to replace. The mainboard is accessible, but many components are soldered, limiting upgradeability. Overall, the phone scores poorly on repairability, which is a common trade-off for innovative designs. Consumers should be aware that if something goes wrong, repairs could be costly and time-consuming.
Implications for the Robot Phone Concept
The Honor Robot Phone represents a bold step into new territory for smartphone design. The gimbal camera offers unprecedented stabilization for video recording, but it comes with trade-offs in durability, repairability, and cost. The durability tests show that the phone can withstand everyday wear and tear, but the gimbal mechanism is a potential point of failure. The teardown reveals that the engineering is impressive but also delicate. For early adopters, the Robot Phone is a fascinating device that pushes boundaries. For the average consumer, it might be too fragile and expensive to maintain. Honor will likely refine the design in future generations, addressing the issues highlighted by Zack’s tests.
What This Means for Consumers
If you’re considering buying the Honor Robot Phone, you should weigh the benefits of the gimbal camera against the potential drawbacks. The phone is not as rugged as a traditional flagship, and repairs could be costly. However, if you’re a content creator who values stabilization above all else, the Robot Phone could be a game-changer. Just be prepared to handle it with care.
Future Improvements
Based on the teardown, there are several areas where Honor could improve. Sealing the gimbal bearings to prevent dust ingress would enhance longevity. Using a more scratch-resistant material for the camera housing would help. Improving repairability by using less adhesive and making the battery easier to replace would be welcome. And perhaps most importantly, increasing the phone’s water resistance rating would make it more practical for everyday use. These are all challenges that Honor will need to tackle if it wants the Robot Phone to become more than a niche product.
Final Thoughts
The Honor Robot Phone is a remarkable piece of technology. Its gimbal camera is a genuine innovation that sets it apart from the crowd. However, as Zack’s durability tests and teardown show, it’s not without compromises. The phone is less durable, less repairable, and more expensive than conventional flagships. Whether these trade-offs are worth it depends on your priorities. For tech enthusiasts and content creators, the Robot Phone is an exciting glimpse into the future of smartphone cameras. For everyone else, it might be best to wait for the second generation, when Honor has had time to iron out the kinks. Either way, the Robot Phone has sparked a conversation about what smartphones can be, and that’s a win for innovation.
