A Thorough Explanation of the iPhone SE Series' Water Resistance | Comparing Each Generation and Key Points for Buying Used

The iPhone SE series continues to enjoy strong popularity due to its cost-effectiveness and compact size. While often chosen as a secondary device or a sub-phone, many users are concerned, asking, "Is the SE series waterproof?" or "Is the waterproofing still effective if I buy a used one?"
This article will clearly compare the water resistance of the SE series, from the first generation to the latest SE3 (2022), explaining how much water they can actually withstand and whether they can be used in the rain or in the bathroom. Furthermore, we'll detail key points for maintaining water resistance when choosing a used SE, and the benefits of purchasing from PRODIG, which offers reliable warranties and support.

iPhone SE Series Water Resistance

While the SE series is popular for its affordability, there are differences in water resistance among its models. First, let's understand the mechanism of water resistance and the distinctions between each model.

Differences in Water Resistance Between Original SE and SE2/SE3

  • Original SE (2016): No water resistance. It does not have an IP rating, so caution is advised regarding water exposure. It's best to avoid using it in the rain or around kitchen splashes.

  • SE2 (2020) / SE3 (2022): Both are rated IP67, meaning they can withstand submersion in up to 1 meter of water for 30 minutes. This is considered splash-resistant for everyday use, so it's safe for rain or splashes in the washroom, but not suitable for baths or seawater.

Water Resistance Level According to IP Rating

In IP67, '6' signifies complete protection against dust ingress, and '7' means it can withstand submersion in 1 meter of water for 30 minutes. However, this performance is for new devices, and its effectiveness gradually decreases with impact and age.

How Waterproof Is It? Usability in Bath or Rain

【OK】

  • Outdoor use on rainy days

  • Splashes in the kitchen

  • Temporary wetting during hand washing

【NG】

  • Prolonged use in the bath (steam can cause condensation inside)

  • Use in pools or seawater (salt can degrade seals)

  • Complete submersion

If you want to maintain water resistance, it's safer to use a waterproof case in conjunction.

Tips for Maintaining Water Resistance in a Used SE Series Device

Many people wonder, "Is the waterproofing really okay if I buy a used SE?" Here are key points to ensure you don't make a mistake.

Factors Degrading Water Resistance to Watch Out for in Used Devices

Water resistance can decrease due to frame distortion or peeling seals. Devices that have been dropped or have unofficial repair history are particularly at risk. If the inspection by a used device vendor is lax, there's a higher risk of water infiltration through invisible cracks.

Points to Check Before Purchase

  • No distortion in the frame or SIM tray

  • Guaranteed against blacklisted devices and confirmed operational

  • Battery capacity of 80% or more

  • Water resistance tested, or detailed condition rank clearly stated

It is essential to choose a used device vendor that meets these criteria.

Increased Peace of Mind with a Waterproof Case

If you're concerned about a used device, adding a waterproof case can provide peace of mind. Choosing a case with an IPX8 rating allows for safer use in the bath or during outdoor activities.

For a Worry-Free Waterproof SE

If you're buying a used waterproof SE, where you buy it is the most important factor. PRODIG ensures all devices are operationally checked, cleaned, and come with a blacklisted device guarantee, so you can choose with confidence.

PRODIG's Warranty and Maintenance Services

PRODIG offers fully functional and blacklisted device guaranteed products. Furthermore, there's a 6-month warranty post-purchase, covering free repairs for any malfunctions. The option to inspect the actual product at their Akihabara store before buying is also a major advantage.
