Frequently Asked Questions

  • How can I reduce my exposure to smartphone radiation?

    In addition to using patch’d it is also important that you follow these four easy steps to protect you and your family from the long-term effects of smartphone radiation.

    1. No Signal, No Radiation

    Not to be captain obvious, but turning off your smartphone when you are not using it is the easiest way to reduce smartphone radiation. But, when would I ever not need my phone on? Well, most likely when you go to sleep at night.

    If shutting down is too scary, consider turning off the cellular radio on your phone. Many smartphones have an ‘airplane mode’ function which shuts down the cellular connection of your phone. You can continue to use most of the normal functions of your phone whilst on airplane mode.

    Feeling bold? Switch off your WiFi so your phone doesn’t try and connect to any networks.

    2. Off The Ear

    When it comes to cell phone radiation, the vital factor is proximity to, coincidently, your vital organs – particularly your brain.

    When you hold the phone to your ear, the radiation penetrates your head and brain. It’s a literal no-brainer. Use speakerphone when talking to significantly reduce the amount of radiation absorption, or try a futuristic alternative like a headset (with no metal parts).  A Bluetooth is also preferable to holding a phone to your ear, just be sure to remove it when you’re not on the phone.

    Unsurprisingly, texting is the best way to minimise smartphone radiation. We like to think the brain is more valuable than the finger. Unless, of course, you’re a hand model. So, when a text will suffice, hold off calling.

    3. Bag it

    If you carry a phone directly against your body you may exceed the international safety standards at which the phone was tested. Yes, the standards somehow don’t cover “wearing” your phone, i.e. holding it in your pocket.

    So keep it out of your pockets and don’t clip it onto your belt, for fashion’s sake. Instead, carry your phone in a bag, backpack, or fanny-pack, for fashion’s sake.

    4. Let kids get bored

    Don’t let children make calls on mobile phones unless it is an emergency. Limit the amount of time they spend playing games or using apps on smartphones and tablets. Ensure that all devices are on airplane mode when they are being used, we promise they won’t know the difference.


  • How does patch’d work?

    The patch’d patent-pending design contains a micro- thin printed circuit board (PCB) coated with layers of specifically formulated dielectric materials. The PCB and dielectric materials act as a coupling device, channeling radiation away from the face side of the phone and the user’s head and body.

  • Is patch’d verified by accredited, independent testing laboratories?

    Yes. patch’d has been tested at independent accredited laboratories in accordance with U.S.A Federal Communications Commission (FCC) standards.

  • Is there a different patch’d for different smartphones?

    Yes, patch’d is specifically designed for each smartphone make. There are currently 3 models of patch’d available:

    • patch’d for iPhone 4, 4s, 5, 5c, 5s
    • patch’d for iPhone 6, 6 Plus, 6s, 6s Plus
    • patch’d for Samsung Galaxy S4, S5

    It is important that you select the correct patch’d for your specific phone make and model.

    We are currently working on developing patch’d for a wider range of models so we can continue to offer protection from radiation to the widest possible market.

  • How do I attach patch’d to my phone?

    Simply peel the backing from patch’d and stick to the back of your smartphone in accordance with the specific placement instructions inside the packaging.

    Make sure the back of your phone is clean and free of any dirt, dust, lint or oils from your hands before applying patch’d. We recommend using a non-abrasive cleaner such as an alcohol wipe. You should also ensure your hands are clean and the back of the phone is completely dry.

  • Can I put a protective case over patch’d?

    Yes, patch’d is micro thin (0.35mm) so it fits under most protective smartphone cases.

    However, aluminum cases or other metal cases should not be placed over patch’d as they may affect the performance of patch’d.

  • Does patch’d need to be applied directly to the phone or can it be applied on top of the phone case/ protector?

    patch’d works by coupling up with your phone’s antennas. In order for it to work properly it needs to be applied directly to the back of your phone and in the specific placement outlined in the application instructions.

  • Does patch’d only work on smartphones?

    patch’d models are customised for the antenna configuration of smartphones only.

  • Will patch’d affect the signal strength of my smartphone?

    Independent tests prove that patch’d will have minimal impact on the signal strength of your smartphone.

  • How long will patch’d last?

    Under normal conditions of use patch’d will last at least 2 years provided it has been well cared for.

  • Can I take patch’d off my phone and reapply it to another phone?

    patch’d should not be removed and reapplied to a new phone as removal may damage the internal structure of the PCB. We advise that you don’t remove and reapply to another phone as this may reduce effectiveness.

  • What happens if patch’d is accidentally exposed to moisture?

    patch’d is a sensitive piece of technology that should be treated carefully and not be exposed to moisture at any time.

  • Is patch’d heat and UV sensitive?

    Similar to your smartphone, it is not recommended that patch’d be left in direct heat or sunlight over an extended period of time as this may affect the performance of the product.
