Understanding Water Resistance
1. What is Water Resistance?
Water resistance in smartphones refers to the ability of the device to withstand exposure to water without sustaining damage. This feature is particularly valuable in protecting the device from accidental spills, splashes, and brief submersions. It is important to note that water resistance is not the same as waterproofing; no device is entirely waterproof.
2. Ingress Protection (IP) Ratings
Water resistance is often measured using the Ingress Protection (IP) rating system. This system categorizes the degree of protection provided against solids and liquids:
- IP Rating Format: The IP rating consists of two digits. The first digit indicates protection against solid objects (dust), and the second digit represents protection against liquids (water).
- Common IP Ratings:
- IP67: Dust-tight and protected against immersion in water up to 1 meter for 30 minutes.
- IP68: Dust-tight and protected against continuous immersion in water beyond 1 meter.
- IPX7: Protected against immersion in water up to 1 meter for 30 minutes, with no dust protection.
- IPX8: Protected against continuous immersion in water beyond 1 meter, with no dust protection.
Oppo A72 Overview

2. Water Resistance in the Oppo A72
The Oppo A72 does not come with an official IP rating for water resistance. This absence of an IP rating indicates that Oppo has not officially tested or certified the device for protection against water and dust. Consequently, while the Oppo A72 may offer some degree of water resistance due to its design, it is not guaranteed or officially recognized.
Design and Durability
1. Build Quality
The Oppo A72 features a glass front, plastic frame, and plastic back. The use of plastic and glass may provide some inherent resistance to minor splashes and spills, but it does not equate to official water resistance.
2. Potential Vulnerabilities
- Ports and Buttons: The Oppo A72 includes a USB Type-C port, a SIM card tray, and physical buttons for volume and power. These components are potential entry points for water. Without rubber seals or protective covers, these areas are vulnerable to moisture intrusion.
- Design Considerations: The device’s design does not include features specifically aimed at water resistance, such as rubber gaskets or sealed ports.
3. User Handling
While the A72’s build quality provides some resistance to everyday wear and tear, users should avoid exposing it to excessive moisture. The lack of an IP rating means that any water exposure could lead to potential damage, especially in critical areas like the charging port or internal components.
Real-World Water Exposure
1. Accidental Spills and Rain Exposure
In real-world scenarios, smartphones often encounter minor water exposure, such as accidental spills or rain. For the Oppo A72, users have reported varying degrees of success in dealing with such incidents. Some users have found that the phone survives minor splashes and brief rain exposure without issues, while others have experienced problems after similar incidents.
2. Precautions and Recommendations
- Avoid Immersion: Do not submerge the Oppo A72 in water. Even if the device seems to withstand minor exposure, prolonged or deep immersion can cause internal damage.
- Drying Procedures: If the device comes into contact with water, turn it off immediately and dry it thoroughly with a soft cloth. Avoid using heat sources like hair dryers, which can exacerbate damage.
3. User Experiences
User feedback varies. Some users report that the Oppo A72 handles light water exposure well, while others emphasize the risk of potential damage due to the lack of official water resistance certification. It is essential to exercise caution and prioritize preventive measures.
Comparison with Water-Resistant Devices
1. Competitors with Official IP Ratings
Many smartphones in the same price range or slightly higher offer official water resistance, which provides users with peace of mind:
- Samsung Galaxy A52: Features an IP67 rating, making it dust-tight and resistant to immersion in water up to 1 meter for 30 minutes.
- Xiaomi Mi 10 Lite: Provides some degree of water resistance, though not officially rated. Users report better handling of water exposure compared to devices without any protection.
2. Trade-Offs in Design and Cost
Incorporating water resistance typically increases the cost of a device. Manufacturers may opt to exclude this feature in mid-range models to keep prices competitive. The Oppo A72’s focus on other features, such as its large battery and quad-camera setup, reflects a balance between cost and functionality.
3. Brand Strategies
Different brands adopt various strategies regarding water resistance. High-end models often feature robust water resistance, while mid-range devices may lack this feature to maintain affordability.
Broader Trends in Water Resistance Technology
1. Increasing Prevalence
Water resistance has become a more common feature in smartphones, even in mid-range and budget devices. As technology advances and manufacturing costs decrease, more devices are likely to include official water resistance ratings.
2. Advancements in Technology
- Enhanced Sealing: Advances in sealing technology are making it easier for manufacturers to incorporate water resistance into devices without significantly increasing cost or bulk.
- Improved Materials: Use of advanced materials and coatings helps in providing better protection against water damage.
3. Consumer Expectations
Consumers increasingly expect water resistance as a standard feature. The growing demand for this capability is driving manufacturers to include it in a wider range of devices.
Conclusion
The Oppo A72 does not come with official water resistance certification, which is a significant consideration for users who prioritize protection against water damage. While the device’s build quality may offer some resistance to minor moisture exposure, it is not designed or certified to withstand significant water contact.
For users concerned about water damage, it is essential to exercise caution and avoid exposing the Oppo A72 to water. The lack of an IP rating means that any water exposure could potentially lead to internal damage.
Comparatively, many mid-range and higher-end devices offer official water resistance, providing added protection and peace of mind. As technology advances, water resistance is becoming more prevalent, and future Oppo models may include this feature.
Overall, while the Oppo A72 offers a robust set of features and a competitive price, users seeking official water resistance might need to explore other options or take preventive measures to protect their devices from water damage.
