Can Wireless Charging Work Through Waterproof Cases?
Posted by New Case on 1st Jan 2026
Wireless charging is now a standard convenience in many modern smartphones. For Australians who enjoy the outdoors or work in wet environments, waterproof cases offer much-needed protection. But a common concern is whether a wireless charging waterproof case can actually deliver on its promise—keeping your phone safe and letting you charge without hassle.
How Wireless Charging Works With Cases
Wireless charging uses electromagnetic induction to pass energy through the back of your phone, provided both your phone and charger support this feature. In theory, a case—waterproof or not—shouldn’t interfere if it doesn’t block too much of the wireless signal. However, real-world experience depends on several factors.
Factors Affecting Charging Performance
- Thickness: Thicker or multi-layered waterproof cases can reduce charging efficiency.
- Materials: Most wireless chargers work best with plastic or silicone cases.
- Seals and Air Pockets: Waterproof cases often rely on seals; trapped air or extra space can impact alignment.
Qi-certified chargers and cases labelled as compatible may offer more reliable results, but not all combinations are seamless.
Practical Tips for Charging Through Waterproof Cases
Choosing a case specifically described as a Qi charging case, or MagSafe waterproof case for iPhone users, increases your chances of a smooth experience. Here’s what to consider:
Case Design Matters
- Slim profiles: Smaller cases generally cause fewer issues with wireless charging performance.
- Exposed or thinner charging areas: Some waterproof cases have thinner panels at the back to encourage better contact with the charger.
Testing and Technique
- Position the phone carefully on the pad—alignment is crucial.
- Check for overheating, which can sometimes happen due to thicker casing.
- Use original or recommended wireless chargers, which often have stronger coils or higher wattage.
Are MagSafe and Qi Features Reliable in Waterproof Cases?
MagSafe technology uses magnets for easier alignment and a more secure fit, making it more dependable with thicker or rugged cases, including waterproof designs. Most reputable MagSafe waterproof cases are engineered to keep charging reliable and consistent, even with added protection.
Qi standard chargers are widely used across manufacturers. As long as a case markets itself as being a Qi charging case, and it isn’t excessively thick, charging is likely to work; though it may be slightly slower than charging without a case.
When Charging Through Case Might Be an Issue
Not every wireless charging waterproof case is equal. Charging can be unreliable in the following scenarios:
- Case is too thick, especially around the coil area
- Case has metal inserts or built-in kickstands blocking signal
- Older phone models or chargers with weaker coils
A quick diagnostic is whether your phone charges consistently on the pad, without needing to shift it around regularly. If not, a different case or charger may improve your results.
FAQ
Does using a waterproof case void wireless charging warranty?
No, as long as you use manufacturer-approved accessories, your charging gear is generally covered.
Can all waterproof cases support wireless charging?
Not always. Some cases, particularly very rugged or older models, can block charging. Look for cases labelled Qi- or MagSafe-compatible.
Will wireless charging through a waterproof case cause my phone to overheat?
Some heat buildup is normal, but excessive heat can be a sign of misalignment or a very thick case. Remove the case if your phone gets uncomfortably warm.
Practical takeaway
Wireless charging does work through many waterproof cases, but performance depends on thickness, materials, and compatibility. Choose cases labelled for wireless charging, check alignment, and be mindful of heat for a practical, hassle-free experience.
