What Is IP Rating (IP67, IP68) and Why It Matters in Bangladesh
When buying a smartphone, many users notice terms like IP67 or IP68 in the specifications. These labels are known as IP ratings, and they indicate how resistant a device is to dust and water. Understanding IP ratings can help users make smarter buying decisions, especially in environments where phones are exposed to rain, moisture, or dust on a regular basis.
IP stands for “Ingress Protection.” The rating is made up of two numbers. The first number refers to protection against solid particles such as dust, while the second number refers to protection against liquids, mainly water. Higher numbers mean better protection. For example, a device with an IP68 rating offers stronger resistance than one with a lower IP rating.
The first digit usually ranges from 0 to 6. A rating of 6 means the device is completely dust-tight. This is important in areas where dust is common, such as busy roads, construction zones, or dry seasons. The second digit ranges from 0 to 9 and describes water resistance. This includes protection against splashes, rain, and temporary immersion in water.
IP67 and IP68 are the most popular ratings found in premium and upper mid-range smartphones. IP67 means the phone is fully protected from dust and can survive immersion in water up to 1 meter for about 30 minutes under controlled conditions. IP68 offers the same dust protection but allows deeper water immersion, usually more than 1 meter, depending on the manufacturer’s specification.
For everyday users in Bangladesh, these ratings are highly relevant. Sudden rain, wet hands, accidental drops in water, or high humidity can damage phones that lack proper protection. An IP-rated phone provides peace of mind during daily use, especially for commuters, outdoor workers, and people who travel frequently.
However, it is important to understand what IP ratings do not mean. An IP68-rated phone is water-resistant, not fully waterproof. The tests are done in fresh water under controlled laboratory conditions. Real-life situations such as saltwater, muddy water, soap, or high-pressure water can still cause damage. Many users assume they can freely use IP-rated phones underwater, which often leads to costly repairs.
Another common misunderstanding is long-term durability. IP protection can weaken over time due to drops, repairs, or wear and tear. Opening the phone for battery or screen replacement may reduce its original water resistance if seals are not properly restored. This is why manufacturers often do not cover water damage under standard warranty, even for IP-rated devices.
Price is another factor to consider. Smartphones with IP67 or IP68 ratings usually cost more because of extra sealing and testing. In Bangladesh, buyers should decide whether this added protection is necessary for their lifestyle. For users who mostly stay indoors and handle phones carefully, a lower-rated or non-rated phone may still be sufficient. For users who work outdoors or travel in unpredictable weather, the extra cost can be justified.
It is also worth noting that some phones offer basic water resistance without an official IP rating. While these devices may handle light splashes, they are not tested or certified to the same standard. An official IP rating provides clearer expectations and more reliable protection.
When choosing a smartphone, IP rating should be considered alongside other features such as battery life, camera quality, and performance. It should not be the only deciding factor, but it can add long-term value by reducing the risk of accidental damage.
In conclusion, IP ratings like IP67 and IP68 explain how well a smartphone is protected against dust and water. For users in Bangladesh, where weather and environmental conditions can be challenging, an IP-rated phone can offer practical benefits. Buyers should understand the limitations of these ratings and use them as a guide, not a guarantee. Choosing the right IP rating depends on personal usage, environment, and budget.
