When we buy a smartphone certified as waterproof, we often think we can relax and let splashes or even an unexpected drop in water not be a problem. However, what happens if that phone needs repair? Does that water and dust protection remain intact, or does it simply disappear without us even knowing?
This is a question many users share, especially when they need to replace their phone's screen or battery. Repairs can have a direct impact on the integrity of the device's seal, and therefore, its ability to withstand liquids. In this article, we'll delve into all the factors that influence a phone's water resistance before and after a repair, analyzing both the risks and precautions to take into account.
What does it mean for a mobile phone to be water resistant?
The water resistance of a mobile phone is determined by a IP (Ingress Protection) certification, which is usually accompanied by two numbers, such as IP67 or IP68. The first number corresponds to the level of protection against dust, and the second reflects the level of protection against water.
For example, a mobile phone with IP68 certification can, in theory, immerse yourself in water fresh water up to a certain depth (usually 1,5 meters) for 30 minutes without damage. But this does not mean that the phone is completely waterproof.The certification is applied under controlled laboratory conditions, not in real-life situations such as a drop in salt water or when the phone is already aged.
Can you lose stamina over time?
Even if the mobile phone has not been opened or repaired, the Water resistance may deteriorate with use and over timeFactors such as prolonged sun exposure, falls, contact with salt water, dust buildup on the vents, or sudden changes in temperature can disrupt the seal that protects electronic components.
Although it is not usual, Intensive use of this resistance can lead to its loss of effectivenessThat is, if, for example, the phone is frequently exposed to water due to trust in its certification, this can damage the internal seals or adhesives responsible for preventing liquids from entering.
What happens when a cell phone is repaired?
This is where we enter more delicate territory. When a waterproof phone is opened to repair any component such as the battery or screen, the hermetic seal that provided that protection is brokenEven with repairs performed by professional technicians, it's very difficult to get the resistance back to what it was originally.
At authorized centers like Apple, special adhesives and tools are used to reseal the device after a repair. However, technicians themselves often acknowledge that They cannot guarantee 100% the same resistance that the device had before being opened.It's similar to what happens with products that claim to eliminate 99,9% of bacteria: there's always a small margin of error.
Common cases that reduce the water resistance of mobile phones
Below, we review the most common situations that can compromise a phone's water resistance, whether after a repair or during regular use:
- Bumps or falls: Even a small crack in the screen or case can allow water to enter the inside of the device.
- Contact with salt water: Unlike fresh water, sea water is highly corrosive and is not covered by IP certification tests.
- Accumulation of dust or debris: Especially in speaker or microphone grilles, it can affect the sealing system without the user noticing.
- High temperature or humidity: Continued exposure to hot or humid environments may deform internal seals and impair protection.
What if the technician says he sealed it properly?
Many forums and online communities such as Apple or HTCMania reflect that even if the technician does his best and uses the appropriate adhesives, The user may notice subtle changes in the assembly of the mobile After the repair. For example, when you press the edges of the screen, you can see them compress slightly, something that didn't happen before. These kinds of details can give clues that the seal isn't perfect.
These changes They do not always imply that water will enter, But Yes, they do increase the risk in case of prolonged contact with liquids.Therefore, it's important to take extreme precautions once your phone has been repaired, even if it still has the IP certification on its spec sheet.
What to do to protect your waterproof function?
Although complete waterproofing cannot be guaranteed, there are certain tips that help maintain the best possible protection after a repair:
- Avoid unnecessary contact with liquids, even if the phone has been resealed.
- Dry the phone immediately If it comes into contact with water, using a soft towel.
- Do not charge the phone if it is wet, as this may cause short circuits in the charging port.
- Use covers or cases with additional sealing if the mobile phone is expected to be exposed to humid or hazardous environments.
- Avoid using it on the beach or in swimming pools, since salt water and chlorine are especially aggressive for internal seals.
Is it worth repairing a phone if this feature is lost?
Determining whether a phone is worth repairing based on its water resistance depends largely on its intended use and the conditions under which it is used.
For many users, Water resistance is not a determining factor in everyday mobile phone use. If you use your phone mostly indoors or under normal conditions, you probably won't notice any difference even if some of that protection has been lost.
But if you are a person who is usually in humid environments, outdoors or simply want to have extra protection against accidents, It may be worth considering whether to change the device or purchase a specialized case. to maintain a similar level of security.
It is essential that if you decide to repair your phone, you do it in a center with experience and use original spare parts and professional adhesives. This will not only affect the device's functionality, but also that fragile water barrier we all take for granted, but which can disappear with the slightest improper intervention.
Although IP-certified phones offer a certain degree of peace of mind, in practice, that protection can be compromised by multiple factors. Repairs, impacts, aging, or even simple carelessness can leave the device's interior exposed. Therefore, using your phone with common sense and not assuming that this resistance protects us at all times is essential. Taking care of your device before and after a repair can make the difference between preserving its integrity or having to deal with unexpected moisture damage. Share this information, and more users will be able to resolve their concerns about whether their phone is no longer waterproof.
