Join us on this exploration of cutting-edge technology and the power of innovation.

Does face ID work after Water Damage?

The Science Behind Face ID

Face ID, pioneered by Apple, is an intricate blend of hardware and software wizardry. Combining a TrueDepth camera system and advanced machine learning algorithms, it captures and analyzes more than 30,000 invisible dots projected onto the user’s face. These dots create a detailed depth map and an infrared image, which are then compared to the stored facial data. The system’s neural engine ensures the accurate recognition of the user’s face, allowing for seamless authentication and device access.

The Water Damage Conundrum:

Water, an ever-present element in our daily lives, can prove to be a formidable adversary for electronic devices. Accidental submersion or exposure to moisture can potentially disrupt the intricate components that make Face ID possible. It is natural to wonder whether water damage hampers the functionality of this innovative biometric feature.

Face ID and Liquid Intrusion:
The TrueDepth camera system, responsible for Face ID’s operation, is composed of multiple sensors and delicate circuitry. While Apple has designed its devices to be water-resistant, it is important to note that they are not completely waterproof. The iPhone and iPad models since iPhone X and iPad Pro 2018, respectively, carry an IP68 rating, indicating their ability to withstand immersion in water up to certain depths and durations.

However, it is crucial to exercise caution, as exposure to excessive water or liquid intrusion can disrupt the functionality of Face ID. The intricate nature of the system’s components leaves room for potential damage from prolonged submersion or the entry of water into vulnerable areas of the device. Despite the robust engineering, water damage remains a potential threat to Face ID’s reliability.

The Aftermath of Water Exposure:

After water exposure, it becomes imperative to evaluate the extent of damage inflicted upon the device, specifically on the TrueDepth camera system and its related components. Understanding the consequences of water damage is crucial in determining whether Face ID can withstand such adversities.

Effects on the TrueDepth Camera System:
Water damage can cause an array of issues within the TrueDepth camera system, potentially impacting Face ID’s functionality. Moisture can corrode sensitive circuitry, disrupt optical elements, or compromise the integrity of the facial recognition sensors. In such cases, the accuracy and effectiveness of Face ID may be compromised, leading to an inability to unlock the device using facial recognition.

Furthermore, water damage can result in condensation buildup within the device, affecting the clarity of the TrueDepth camera’s lens and infrared capabilities. This may impede the system’s ability to accurately map the user’s face and compare it to the stored facial data, resulting in failed authentication attempts.

In summary, water damage poses a significant risk to Face ID’s functioning due to the intricate nature of the TrueDepth camera system and its susceptibility to damage from liquid intrusion. While Apple’s devices are designed with water-resistant features, prolonged exposure or excessive liquid intrusion can compromise the delicate components essential for Face ID’s operation.

Mitigating the Risks

While water damage may pose a threat to Face ID’s functionality, there are measures one can take to minimize the risk and potentially restore the Face ID feature. Let us explore some strategies that can help mitigate the risks associated with water damage.

Quick Action and Drying:
In the event of accidental water exposure, acting swiftly is crucial. Remove the device from water immediately and power it off to prevent any potential short circuits. Gently pat the device dry with a soft cloth, avoiding excessive pressure or rubbing, which could further spread moisture within the device. It is important not to use heat sources such as hairdryers or ovens, as excessive heat can damage the device further. Instead, opt for natural drying methods.

Silica Gel and Desiccant Packs:
Silica gel and desiccant packs can prove invaluable in absorbing moisture from electronic devices. Place the device in a sealed container along with several packets of silica gel or desiccant packs. These desiccants are designed to draw moisture from the surroundings and aid in the drying process. Allow the device to sit in the container for at least 48 hours, ensuring that the moisture is fully absorbed.

Professional Assessment and Repair:
If the water damage is substantial or if Face ID fails to function after drying attempts, seeking professional assistance is advisable. Apple authorized service providers or technicians specializing in electronics repair can assess the extent of the damage and perform the necessary repairs. They have the expertise and tools to disassemble the device, clean any corrosion, and replace damaged components. Professional intervention offers the best chance of restoring Face ID’s functionality after water damage.

Alternative Authentication Methods:
While waiting for repairs or if Face ID cannot be restored, alternative authentication methods can be utilized to unlock the device and ensure continued access. Apple devices provide options such as passcodes, PINs, and pattern locks, which can serve as temporary alternatives. Although not as convenient as Face ID, these methods maintain device security and allow for regular use until Face ID is fully operational again.

The Future of Face ID

As technology advances, the resilience of Face ID in the face of water damage may improve. Tech giants like Apple continually invest in research and development, exploring ways to enhance the durability and water resistance of their devices’ components. Future iterations of Face ID may incorporate even more robust measures to safeguard against water damage, ensuring greater reliability in diverse environments.


While Face ID presents a remarkable leap in biometric authentication, its functionality can be affected by water damage. The intricate nature of the TrueDepth camera system and its susceptibility to liquid intrusion pose potential risks to Face ID’s accuracy and reliability. Timely action, proper drying methods, and professional assessment can help mitigate these risks and potentially restore Face ID’s functionality. In the event of persistent issues, alternative authentication methods provide temporary solutions. As technology progresses, we can expect further advancements in waterproofing measures and the resilience of Face ID. Until then, it is essential to exercise caution and protect our devices from water-related mishaps.
