Part Descriptions

Front Cover

The front cover has two openings on the top edge. The large opening allows access to the headphone jack and can be sealed with the headphone jack cover. The smaller opening channels sound to the sound-cancelling feature of the iPhone and are sealed with a waterproof membrane.

The front cover also has three openings on its bottom edge. The large central opening allows access to the charging dock connector and is sealed by the latch cover on the back cover. The two smaller openings on either side of the charging dock connector allow sound in and out of the case and are sealed with a waterproof membrane.

The front surface of the front cover also includes an opening for sound transmission and this opening is also covered by a waterproof membrane.

Note Visually check all outer and inner surfaces of the front cover for damage. Check all openings and make sure they are capable of being sealed by the headphone jack cover or the latch and that the membrane are fully intact and covering the openings.

Back Cover

The back cover has a channel, which holds the O-ring, and a latch with an attached gasket. The back cover also includes two lens windows that are sealed by a plastic screen.

Note Visually inspect the back cover, the O-ring, the back latch and gasket, and the lens windows. The O-ring should fit snuggly within the channel and the gasket should be firmly affixed to the back latch cover.

Headphone Jack Cover

The headphone jack cover screws into the opening on the front cover and provides a watertight seal when you are not using Apple headphones.

The Headphone Jack cover must be screwed in tight to be waterproof.

Accepts Apple headphones.

The General Use headphone adapter screws in here to make it completely waterproof and dust-proof and works with any earphones.

Headphone Adapter

The Headphone adapter screws into the opening on the front cover and allows you to use your favorite headphones or ear buds while maintaining the watertight seal. You can use Apple headphones with the case; however, they do not provide a watertight seal.

The Camera or "Flash" Cover

No expenses spared here real professional camera grade glass lens with double coated optics.

Must be kept clean inside and out for clear pictures. Don't stick your fingers here.

Main O-ring seal

This is what keeps your iPhone safe and dry so it is really important to keep this super clean and never allow dirt, crumbs, or fine hairs to cross it.

Bottom speaker and microphone vents

Never poke or touch these. Specially designed to allow sound to pass in and out of the case and allow air pressure to equalize while preventing water entering the case.

For enhanced sound quality the back of the case is used as a speaker / bass response and on the top of the case next, to the headphone jack cover, is the noise canceling microphone vent for best sound quality.

Charge Port Door 

Seals the bottom when closed.

Never scrub or scratch the seal as you could damage its skin and ability to seal.

Squeeze the back of the charge port door.

Water Test

The first and most important thing to do is to do a water test.

This is so you can see how the case goes together and make sure you are closing it right to be waterproof.

This also verifies that everything is working correctly and it gives you the confidence to trust it with your iPhone.

Assemble the LifeProof Case

  1. Pick up the front of the case, holding it by the sides.
  2. Line up the back of the case with the front.

  1. Squeeze the top edges together with both hands: thumbs on top, fingers beneath, so that the pieces click into place.

  1. Work your way down both sides in small increments, squeezing the front and back of the case together with your forefingers and thumbs all the way to the bottom.

  1. Place the case face down on a smooth, hard surface such as a table-top. Firmly press around the entire perimeter of the case.
  2. Squeeze the front and back together near the charge port door. This area is easy to miss so check it carefully.

  1. Apply firm pressure in a rubbing motion around the inside rim of the back of the case to ensure that all internal latches are sealed.

The case should be entirely snapped closed all the way around the perimeter.

  1. Visually check the case to make sure the seam around the edges is fully closed with just a very fine evenly spaced gap between the front and back.

This is important to do every time before you put your case in water to make sure it has not come open a little from an impact or other stress to the case.

  1. Close the charge port door firmly until it snaps shut.

  1. Screw the headphone jack cover into the headphone opening so that it is tightly closed.

You are now ready to do the water test.

Test the Watertight Seal

  1. Find a container large enough to submerge the case, such as your kitchen sink.
  2. Fill the sink with water at least half full.
  3. Place the case in the water and weigh it down with something handy, but not too heavy, such as a coffee mug full of water.

A few air bubbles may escape from the waterproof sound holes.

  1. Leave the case under water for 30 minutes.
  2. Take the weight off of the case and then remove the case from the water.
  3. Shake off the excess water and look into case through the front window.

There should be no visible water drops inside although some minor condensation might appear if there is a significant difference in temperature between the water and the room.

If it looks dry inside, the case has passed the test.

If there is excessive water inside the case, open the case (following the instructions in the next section), then reassemble the case carefully and try the test again. If you are still having trouble obtaining a watertight seal, contact LifeSupport at for possible solutions.

Open the LifeProof Case

You must open the case carefully according to these instructions.

  1. Open the charge port door.

You will notice a little slot to the left of the charge port opening to help you open it.

  1. Flip the case over so it is face down with the top of the phone facing toward you and the bottom facing away from you.

  1. Place a coin into the slot and carefully start separating the front and back.
  1. Slide your fingers into the bottom area of the case just inside where the charge port door opens and also pop open the other side of the latch opening.
  2. Starting from the bottom, pull the back of the case gently away from the front of the case.

Do not peel back the case and bend it as this will damage it but support it with hand and see-saw it from side to side.

Warning Do not peel the back open at a steep angle without using your hand to support the case and keep it straight. Do not peel it off like a banana peel; this will damage the case.
  1. While applying gentle pressure to insert your fingers and palm deeper into the back of the case between the iPhone and the case back, keep the back of the case straight and slightly rock (rotate) your wrist back and forth while gently lifting the case back. The wrist rocking back and forth motion with release the latches on each side in succession.

  1. Ensure you start at the bottom and peel both sides off evenly leaving the top of the case until last. It helps to get your finger on the inside of the back to help support it so it does not bend the sides.
  2. The very last step is to peel the top away from the case at a diagonal gentle angle.

Install your iPhone

Clean your iPhone


  • Your iPhone must be absolutely totally clean before you put it in the case.

This is so you don't get ugly 'oily wet looking areas' on your touch screen.

  • Keep out all dust and damaging particles.
  • Make sure you have the clearest possible picture.

Insert your iPhone

Place your iPhone into the front cover, face down, and press firmly into front cover.

Close the Case

To close the case and complete installation, follow the steps in "Assemble the LifeProof Case" above.


  • Check the watertight seal
  • Check for fine hairs, dust, crumbs, and lint
  • Remove debris
  • Close the charge port door
  • Screw in the headphone jack cover
  • Press the home button to check your iPhone works

Operating Your LifeProof

This is really pretty simple as everything works the same as your iPhone.

IMPORTANT REMINDER Before entering any potentially hazardous situation, make sure all important data is backed up as a precaution.

All the same features work and are fully accessible:

  • Buttons
  • Silence switch
  • Camera
  • Microphone
  • Speakers
  • Charging


  1. Open the charge port latch cover.

  1. Plug in your Apple USB cable.
  2. When charging is complete remove the USB cable and snap the door firmly closed again.
  3. Clip the door firmly closed again.

Many third party USB cables are too fat to fit in into your LifeProof charge port door. We recommend only using the Apple USB cable, or you can purchase more USB cables from the LifeProof website to use with your car charger or other computer components.

Also, if you want to use it with a speaker-dock, you can use a dock extender (available from so that it fits the dock.


The headphone jack cover screws in at the top of the case. This is really important as it keeps dust and water from getting inside. It needs to ALWAYS be screwed in when you are not using headphones.

Unscrew it when you are ready to use your headphones. Be careful not to lose it. There is a Keeper that you can clip onto your headphone cable, so simply press it onto the headphone cable as soon as you unscrew it. Don't worry too much, however as there is a spare jack cover included and you can also buy more from if it gets lost.

You can plug in your Apple headphones directly into the headphone jack as most other headphone jacks are too fat to fit into the slim LifeProof case. We recommend always using either the General Use of the Swimming headphone adapters because they seal 100% of the water, dust, and other problems out of case.

Just push the headphone adapter in until it stops, then screw it firmly closed. Now you can plug any headphone into the jack at the top of the adapter.

To remove the headphone jack cover, simply unscrew it.

Remember to take the headphone jack cover out of the Keeper and screw it back in.


All buttons work the same as usual.

Silence switch

Easily switches between silent mode and ringer on.

Switches the opposite direction to the iPhone.

Use your finger or thumb pad, not your fingernail.

Volume buttons

Works the same as usual.

Power button

Works the same as usual.

Home button

Press it firmly in the center to activate.


Touch sensitivity should be very similar to the naked iPhone screen.

The touch screen will not respond underwater. This is normal. If you want to record video you will need to start and stop it above water.

Making a call

Everything works just like your iPhone.


The speaker actually enhances the bass and makes it sound better.

Play some music and you will feel the back of the case acting as a speaker.


Your earpiece works normally. Never poke or pierce the vent as this could render it not waterproof.


All microphones including the noise-canceling microphone have special waterproof vents that allow the sound to get in and out but keeps water out. It even works underwater so your underwater movies have sound.

The Four Proofs: Water, Dirt, Snow, Shock

LifeProof is designed to be used in all areas of your daily life so you can have confidence and freedom to stay connected wherever you are with whatever you're doing.

LifeProof was designed to be as thin, light, convenient, and beautiful as possible while still providing reliable protection. It is meant to provide reliable protection if cared for; however, it is not indestructible. If damaged it may no longer provide full protection against all the four Proofs. If you handle your LifeProof with respect and care, and maintain it well, it will deliver years of dependable service.

Do not subject the case to intentional impacts or abuse as this will cause excessive wear and tear and you might push your LifeProof beyond its ability to protect your iPhone. You might damage the LifeProof waterproof or dust-proof protective capabilities.

VERY IMPORTANT Before you expose the iPhone to water, dirt, snow, or shock, check the following before each outing:
  1. The entire case is undamaged-no cracks, deep scratches, dents, or rips in the silence switch, boot, or touch screen. If either the front or back of the case is damaged you can order a replacement part from the LifeProof website at a reasonable cost.
  2. Make sure the case is tightly snapped closed all the way around. Check for any uneven cracks and press closed. It is possible for the case to open slightly after impacts.
  3. The headphone jack cover or headphone adapter cable is installed and tightly closed.
  4. The charge port door is closed.


LifeProof is designed to reliably seal your iPhone against water provided you carefully follow the instructions.

During Use

Never open the charge port door, case, or headphone port while in water as it will flood the case, causing damage to your phone.

You can use all features as normal above water.


Feel free to use the LifeProof case freely in the pool, ocean, hot tub, or in severe weather.

Do not exceed a depth of 6.6 feet (2 meters) underwater. While the case has been tested to substantially greater depths, it is sensible to allow for this margin of safety to avoid disappointment.


In underwater environments, the touch screen will not respond because of how the electronics work. You can use the touch screen above water to start and stop video recording or music playback if you like.

The video camera and microphones continue to function under water.

Wireless signals do not work well under water and may fade.

When you come to the surface, some water may be trapped on the outside of the camera lens. A quick shake of the phone should remove it instantly.

It is usual to see a small stream or bubbles escaping from the microphone or speaker vents when first submerged.

After Use

Clean your case liberally with clean fresh water to rinse off all salt, dirt, sand, or chlorine. Shake off excess water and dry with a clean, soft cloth.


LifeProof is designed to IP68 international standards which keeps out all minute dust particles.

It can be used in all kinds of dirty environments:

  • Farming
  • Construction
  • Disaster
  • Beach
  • Around food and drinks
  • Children's playgrounds

Clean liberally with mild soap and fresh water to remove all dirt and mud. Shake off excess water, then dry off with a clean, soft cloth. See Care and Cleaning for more information.


  • Do not expose to temperature extremes, and if you can, keep it in your pocket.
  • Have the General Use headphone adapter installed if you are listening to music in sleet or snow.
  • Wash off snow and ice and it's as good as new.
  • Even though the case by itself can withstand temperatures from -40°C (-40°F) to 60°C (140F), Apple recommends that your iPhone should stay between 0°C (or 32°F) and 35°C (or 95°F).


Although LifeProof is designed and tested to military specifications, you should not intentionally drop your case or subject it to harsh treatment as you may get unlucky and accidentally exceed the ability of the LifeProof case to protect your phone.

Also, it is possible that shock damage to your iPhone is cumulative and an accrual of impacts that may cause failure down the road. Think of LifeProof as an airbag to help protect your iPhone when accidents happen. Treat it respectfully and with care and it will provide a long and reliable life.

If your iPhone screen makes contact with a hard object at velocity, the glass may become damaged.

After an impact or significant shock, inspect the LifeProof and ensure the entire case is undamaged - no cracks, deep scratches, dents, or rips in the silence switch boot or touch screen. If either the front or back of the case is damaged you can order a replacement part from the LifeProof website at

If your LifeProof case has experienced a very severe impact or if there are visible minor dents or scuffs we recommend performing a water test again without the iPhone to ensure all protective capabilities are intact.

Care and Cleaning


Maintain regular backups of your iPhone data, especially before entering a situation with a high chance of theft or harsh environments. Every extreme situation carries a risk of unexpected extremes that may exceed your LifeProof case's ability to protect your iPhone.

  • Avoid needless drops or impacts to your LifeProof case as damage to the case or iPhone is always a possibility.
  • Perform a water test after each serious impact.
  • Do not use abrasives, solvents, bleach, petroleum, or oxidizing agents on the case.
  • Although the screen has a scratch resistant coating, avoid placing your LifeProof screen where it can be scratched or gouged.

Avoid Temperature Extremes

  • To ensure longevity and correct operation of your iPhone, do not exceed Apple's recommended operating temperature of 0°C or 32°F to 35°C or 95°F.
  • For the case alone, do not expose the case to temperatures outside of -40°C (-40°F) and 60°C (140F).
  • Avoid allowing people inexperienced in the operation of the case to use it in water. They may open a port or do something that could result in leakage. This especially applies to children with curious fingers.


  • Do not use bleach, solvents, or abrasive polishes.
  • Do not use abrasive cleaning pads or brushes as these could scratch the optical surfaces or case finish.
  • Do not put the case into the dish washer due to the harsh chemicals and excessive heat.

Case Exterior

  • For minor cleaning, wipe with a warm, damp, soft cloth.
  • For a more thorough clean, ensure all ports are closed and wash under fresh running water.
  • Use a mild detergent as needed. Rinse thoroughly.
  • Shake excess water off and dry gently with a clean, soft cloth.
  • Use an eyeglass-safe microfiber cloth if further wiping is needed on the touch screen area.

Case Interior

  • To clean the inside of the case, open the case and remove the iPhone.
  • Use a mild detergent and soft cloth with warm fresh water to clean. Rinse well.
  • Shake excess water off and dry gently with a clean, soft cloth.
  • Use an eyeglass-safe microfiber cloth if further wiping is needed on the touch screen area inside.
  • Ensure all parts of the case are clean and dry, and check that the O-ring is correctly seated in place and clean without any lint before following the reassembly instructions.
  • To clean the O-ring, tap it out of the case, remove the O-ring, and wash it with detergent and warm fresh running water. Do not set it down on any surface. Shake to dry. Align the top corners first and press the remainder until the bottom. Never use silicone lubricants.


  • When using underwater ensure the O-ring is regularly cleaned.
  • If using in underwater situations we recommend using petroleum jelly on the O-ring and apply between 'tweeze fingers' (or three fingers put together) and reinsert O-ring.
  • Warning: Do not use silicone grease.
  • Inspect the O-ring channel to ensure it is clean as any lint, dirt, sand, or muck will cause the case to leak.

Camera Lens

  • To clean the camera lens, use rubbing (isopropyl) alcohol or methylated spirits on a cotton tip (Q-tip). Clean the inside and outside of the camera lens as needed.

Touch screen

  • Use an eyeglass-safe microfiber cloth if minor wiping is needed. For more thorough cleaning follow the instructions to clean the case exterior.
