1 The front is mostly made out of a glass screen and an LCD underneath it. If this part is not handled with care, the glass can shatter and/or the LCD can break.

2Almost all screws inside of the phone are of different lengths. After the screws are removed, they need to go back into the same place they were removed from or else the motherboard could get damaged. Pay attention to this during reassembly. Organize the screws when removing them!

3All lithium batteries contain chemicals that are necessary to store power. These chemicals are safely stored inside the battery as long as the battery is not physically damaged. Puncturing, damaging, or cutting a lithium battery can result in combustion (fire).

4Back-up your phone prior to the battery replacement. No data will be lost if the replacement goes as a planned but unforeseen complications can arise, although they are uncommon.  

VIDEO GUIDE

Detailed step-by-step text/image guide for iPhone 7 and 7 Plus battery replacement.

NOTE:

The first waterproof phones made by Apple are the iPhone 7 and iPhone 7 Plus. These phones have been rated by the IEC as IP67. This means that these phones have been tested and passed to be dust proof and waterproof, however, the phone's gaskets and "waterproof" adhesives degrade over time and water can potentially seep through.
The phone manufacturer's warranty does not cover liquid damage and as such, it is suggested to prevent the phones from getting wet.

Any waterproofing-effect the original adhesive may have could be compromised during disassembly and reassembly. 

Step 1

Removing the Pentalobe Screws

Turn off the iPhone.
Locate the two pentalobe screws at the bottom and remove the screws.
Place the screws in a secure area. The iPhone screws are tiny and can be blown away.

Turn off the phone.

Remove the pentalobe screws using the pentalobe screwdriver.

 Step 2

Opening the Phone - I

Place the suction cup tool just above the home button.
Do not place it directly or partially over the home button. Doing so will prevent the suction cup from adhering to a flat surface. 

Pull the suction cup gently but firmly to lift the front assembly. Lift the screen only enough to expose an opening between the front assembly the back assembly. 

When an opening has been created, use the prying tool or the tweezers to pry open the phone. Make sure to go between the frame of the screen and not on the glass. 

If the screen does not seem to lift, use a heat gun or a hair dryer and heat the 4 sides of the phone. Do not heat it too much to avoid damage. It should be just enough to soften the adhesives. If the surface of the phone is too hot to touch, you are already heating it too much.

* The tweezers can leave a tiny mark on the back assembly, be careful!

iPhone 7/7 Plus Battery Replacement - Opening the phone - 3
iPhone 7/7 Plus Battery Replacement - Opening the phone - 4

Position the suction cup just above the home button.

Lift the suction cup gently but firmly.

Insert the spudger tool just above the speakers to assist the suction cup in pulling up the screen assembly.

Insert the spudger tool carefully above the speakers and between the metal frame of the phone screen and the bottom assembly.

Step 3

Opening the Phone - II

Once an opening has been secured, use the plastic prying tool to slide between the metal frame and the bottom assembly. This will help completely separate the adhesives and the front assembly from the bottom assembly. 

Slide the plastic prying tool from the bottom and to the sides up to the top corner but do not slide at the top portion of the phone yet as there are two tabs sticking underneath the front assembly. 

Keep in mind that the front assembly flex cables are located at the right hand side of your device. Please be careful not to damage the flex cables.

iPhone 7/7 Plus Battery Replacement - Cutting the screen adhesives - 3
iPhone 7/7 Plus Battery Replacement - Cutting the screen adhesives - 4

Gently slide the prying tool along the edges of the phone to cut the phone screen adhesives.

Continue sliding the prying tool only up to the top corner.

The phone screen flex cables are located at the right hand side both at the bottom and top. 

Keep cutting the adhesives as this makes it easier to remove the phone screen.

Once the adhesives from the sides and the bottom have been cut, gently pull the screen up and downwards so that the tabs will be unhinged from the bottom assembly. It will also make room for the plastic prying tool to slide at the top. 

iPhone 7/7 Plus Battery Replacement - Opening the phone screen - 1
Phone 7/7 Plus Battery Replacement - Opening the phone screen - 2

Gently pull up the phone screen to make room for the prying tool to slide and cut the top adhesive. 

To unhinge the tabs, pull up the phone and pull downwards. 

Step 3 

Opening the Phone - III

The iPhone 7 and iPhone 7 Plus' phone screens open sideways going to the right hand side.

Keep in mind that the screen is connected to the motherboard with flex cables that are sensitive and may be damaged if stretched, bent, folded, or any physical damage. These flex cables control the ear speaker, front facing camera, LCD, touch screen, and home button.

There are two ways to proceed with the battery replacement; (a) stabilizing the screen assembly or (b) removing the screen assembly altogether. 

A. The screen is secured with a rubber band to a book, box, or similar object.
Downside: Less flexibility and less room to work with your hands. If the phone or box is moved, it can put tension on the flex cables, potentially damaging them.
Upside: Save yourself the hassle of removing the screen. The tiny screws and connectors can be a challenge to handle. 
If you opt for this option but regret it in the coming steps, you can always come back to this step and remove the screen.


B. Completely removing the phone screen.
Downside: Removing, keeping track of, and putting back the tiny screws can be challenging. The small connectors that connect the flex cables to the motherboard can also be difficult to re-connect during re-assembly. A bit of extra work.
Upside: Without the screen attached to the motherboard you can move around the back assembly as you see fit and there's no risk of putting tension on the flex cables.

There is no right or wrong option. It's a personal preference. The chocie is yours to make.

iPhone 7/7 Plus Battery Replacement - Opening the phone screen 3 - 1
iPhone 7/7 Plus Battery Replacement - Opening the phone screen 3 - 2

Open the phone screen towards the right.

Be careful not to cause too much tension on the phone screen cables to avoid damage.

iPhone 7/7 Plus Battery Replacement - Opening the phone screen 3 - 4

These flex cables can be easily damaged. 

iPhone 7/7 Plus Battery Replacement - Opening the phone screen 3 - 5

Flip the phone screen gently towards the right side. Leaving the suction cup attached will decrease the tension on the flex cables while the screen is folded.

iPhone 7/7 Plus Battery Replacement - Opening the phone screen 3 - 6

The screen can lie flat at a 180 degree angle without significant tension on the cables if positioned correctly. This is, however, a risky move.

You can secure the phone screen with a rubber band to a book, a box or anything stable. 

Step 4

Testing the New Battery

Using the tri-point screwdriver, remove the screws of the metal shield that covers the battery and the phone screen connectors. Place the screws in a secure area.
Using the plastic spudger tool, carefully disconnect the original battery's connector. 

Take out the battery from the anti-static, heat-sealed plastic bag. The battery is also wrapped in clear plastic, remove this as well.
Place the new battery on top of the old battery and connect the new battery's connector to the connector port on the motherboard. If done properly, the connector will snap into place. 

Carefully close the phone screen. Turn on the phone and check the battery health.
The battery should come at least 15% charge. If this isn't so, try to charge the battery at this point.

-If the battery charges, you can stop charging and proceed with the replacement process.
-If the battery does not charge, please contact support.

Turn off the phone after checking and disconnect the new battery's connector. 


* Keep the screws in a secure area away from gusts of wind. The screws must also be inserted back to their original slots as these have different sizes. Inserting a screw to a wrong slot can potentially damage the motherboard.

Lay the screen gently back to its original position and power up the phone.

Check the battery level and health.

If the battery level and health are okay, power off the phone and proceed to the next step.

Step 5

Removing the Phone Screen Assembly

After disconnecting the new battery's connector, carefully disconnect the phone screen cables, assuming the screen is not fixed to a solid object.

Using the Phillips screwdriver, remove the metal shield of the phone screen cable at the top part of the phone and disconnect the flex cable.

Reminder: Place the screws in a secure location and remember where these screws are to be inserted. Some of the screws have different lengths and if inserted to a wrong slot can potentially damage the circuit board.

The top metal shield have two 1.0mm screws and a 1.3mm screw. The two 1.0mm screws are installed at the motherboard side of the metal shield. The single 1.3mm screw is installed near the camera and just above the battery.

Use the tweezers to pick up and remove the metal shield. Place it in a secure area with the screws.

Use the spudger tool to disconnect the remaining phone screen cables.

The phone screen assembly is not separated.

Step 6

Removing the Taptic Engine

Using the Phillips screwdriver, remove the 3 screws holding the taptic engine (one screw on its right side, two on its left).

Using the Phillips screwdriver, remove the 2 screws holding the plastic shield covering the taptic engine's connector. 

Use the prying tool and disconnect the taptic engine's connector. 

Reminder: Place the screws in a secure location and remember where these screws are to be inserted. Some of the screws have different lengths and if inserted to a wrong slot can potentially damage the circuit board.

Use the tweezers and remove the taptic engine carefully.

Step 7

Removing the Adhesives and the Battery
(commonly regarded as the most challenging step)

The battery adhesives can be quite a task to pull out. Below are ways that we recommend to successfully remove the adhesives.

Using the tweezers or the prying tool, peel off the tabs (both the black and white tabs).

Grab the end of the adhesive (both the black and the white part – if only grabbing the black part, the strip rips easily) and pull the adhesive down and outwards from the phone, in the direction of the charging port. Before pulling the adhesive, it helps to heat lightly the back (outer) side of the back assembly with a heat gun or a hair dryer.

Do not heat it too much! If you cannot hold and keep your finger on the back assembly, it is too hot!

If the adhesive tears as you pull it, which is not uncommon, you now need to lever the battery out using the broad yellow prying tools. This is the less ideal way of removing the battery. The adhesive holds the battery much stronger than necessary so patience and a slow but steady hand are key.
Keep in mind that the battery may combust if it has suffered extensive physical damage or if it's punctured or pierced. Be extra careful in prying the battery out.

Try to lever the battery from the left side of the phone using the broad prying tool. Lever the prying tool only at the left side but just below the volume buttons.  This process can take up to 5-10 minutes. The battery might only loosen a tiny bit at a time. Be patient, move slowly and carefully. If the battery will not come loose from the adhesive, use a heat gun, a hair dryer or a warm halogen (LED is not warm enough) lamp to lightly heat the back (outer) side of the back assembly. An elevated temperature makes the battery loosen easier from the adhesive when levering.

Do not heat it too much! If you can not hold and keep your finger on the back assembly, it is too hot!



IMPORTANT:
1. Do not lever the battery up from the right hand side where the motherboard is located. By levering against the motherboard there is a significant risk of damaging components.
2. Do not lever the battery from the top left corner. The volume key cable runs underneath the battery and it gets easily damaged by the tweezers.
3. Do not puncture, damage or severely bend the battery. The battery can combust (catch on fire) if it is pierced or severely bent. If your battery is already damaged or swollen, it is extra sensitive!.

iPhone 7/7 Plus Battery Replacement - Removing the adhesives - 4

Use the spudger tool to open the adhesive's flaps/tabs.

Use the tweezers to completely open the black and white tabs.

The tabs (black and white) should be completely opened.

To soften the adhesives, heat the back side of the phone. Heat only from the volume button towards the bottom.

iPhone 7/7 Plus Battery Replacement - Removing the adhesives - 6
iPhone 7/7 Plus Battery Replacement - Removing the adhesives - 7
iPhone 7/7 Plus Battery Replacement - Removing the adhesives - 8

Gently pull the adhesives.

Pull the adhesives towards the side of the phone. Pulling along the sides instead of downwards decreases the changes of the adhesive tearing.

Continue pulling the adhesives gently. Too much pressure in pulling can tear the adhesive.

The adhesives run the length of the battery. Be patient in pulling the adhesives out.

iPhone 7/7 Plus Battery Replacement - Removing the adhesives - 9

Set aside or dispose the old adhesives.

Pull out the second adhesive gently.

iPhone 7/7 Plus Battery Replacement - Removing the adhesives - 14

Pull  and run the adhesive towards the side as well.

iPhone 7/7 Plus Battery Replacement - Removing the adhesives - 15

If the adhesives are torn, use the prying tool and gently pry the battery out.

iPhone 7/7 Plus Battery Replacement - Removing the adhesives - 16

Keep prying the battery out gently to avoid damaging the phone.

iPhone 7/7 Plus Battery Replacement - Removing the adhesives - 17

The battery is now completely removed. 

You can also use the spudger tool to pry out the battery.

Be careful when prying out the battery to avoid puncturing or bending it too much. 

After prying out, the battery may be physically deformed. Keep in mind that it may combust if it gets bent too much or punctured.

An expected slightly bent battery after prying. 

Step 8

Installing the Adhesives and the New Battery


Remove the blue plastic sheet, starting at the pointy side and place it on the battery. Align the black tabs to the bottom of the battery. Lay the strips down and press the adhesives gently. 

Remove the second, pink, plastic sheet to expose the adhesives. Gently place the battery in the phone and make sure that the battery's connector is aligned to the connector port on the circuit board.

At this point, you can stick and close the adhesives' black tabs or you can do it after reinstalling the taptic engine. 

REMINDER: The battery should be placed properly. The adhesives are very sticky and can easily stick to any surface once the wrapper is removed. You only get one shot at this.
If you don't get it right, any type of household tape can be used as substitute. Scotch tape or duct tape works well. Cut about a two inch (5 cm) piece and make a loop out of it, with it's sticky side out. If using a strong tape, such as duct tape, one loop is enough. If using a weaker adhesive, such as scotch tape, two loops are likely needed to hold the battery in place.


CAUTION: Do not connect the battery connector to the connector port just yet. The battery can be connected at Step 10 when the phone screen has been reconnected.

The adhesives are very sticky. Be careful not to touch or let anything touch the surface.

Place the new battery in the phone.  The battery connector should be perfectly aligned to its connector port in the circuit board side.

Press the battery gently but firmly.

Step 9

Reinstalling Taptic Engine.

Position the taptic engine and connect its connector. Place the plastic shield on top of the connector and reinstall the screws in the order that it was originally installed.

If you did not stick and close that black adhesive tabs, you can do so now. Remove the blue plastic sheet that covers the black tabs and press the tabs to the battery.

Remove the adhesives blue protective sheet.

Press and stick the adhesives tabs on to the battery.

Step 10

Installing the Screen Adhesive

Note: The screen adhesive is not a guarantee that the device will be completely waterproof. The adhesive is very sticky and will stick to any surface. Be careful in placing the new adhesive.

Using the tweezers or the prying tool, clean the edges of the phone by removing the remains of the phone screen adhesive. If the edges are not clean, the new adhesive will not adhere properly. 

Take the adhesives and without removing the protective sheet, try to measure and check the alignment of the adhesive to the phone.

Remove the plastic protective sheet and gently place the adhesive on the phone. Pay attention to the hole at the top right corner of the adhesive. The camera (located at the top right corner of the phone) should fit in the corner hole of the adhesive. This hole serves as a guide.

Once the adhesive has been placed, use the plastic prying tool to press on the adhesive to make sure that it has adhered well.

Finally, remove the remaining adhesive's protective sheets. 

iPhone 7/7 Plus Battery Replacement - Installing the screen adhesive - 1

If the adhesive is coming of the phone's body while removing the plastic film, guide or press the adhesive with the tweezers.

Step 11 

Reinstalling the Phone Screen.

Note: Reconnect the battery connector only AFTER all the phone screen connectors have been reconnected.

Reconnect the front assembly in a similar fashion as when you disconnected it. Hold it in place so that the top of the front assembly and the top of the back assembly are next to each other. 

Using your finger or the spudger tool, reconnect the connectors gently in their respective connector ports. Do not put too much pressure on the center of the connectors. We recommend pressing on one end of the connector first and slide your finger to the other side of the connector. If done properly, the connectors will snap into place.

Begin with the ear speaker and front camera connector in the top right side of the phone.
Proceed with the two screen (LCD, touch screen, and home button) connectors. 

Connect the battery connector. 

Once all of the connectors have been reconnected, reinstall the metal shields. Make sure that the screws are inserted to their original slots. 

There are instances when lines appear on the phone screen. It can take up to 60 minutes of use before the lines will fade. If not, please contact support.
