iPhone 6S Battery Replacement In Kolkata

 

Step 1. Pentalobe Screws

Power off your iPhone before beginning disassembly.
Remove the two 3.4 mm P2 Pentalobe screws on the bottom edge of the iPhone, next to the Lightning connector.

Step 2. Opening Procedure

 

removing iPhone 6s display

 

Opening the display on the 6s separates a thin strip of adhesive around the perimeter of the display. If you prefer to replace the adhesive, have a set of new adhesive strips ready before you continue. It’s possible to complete the repair without replacing the adhesive, and you probably won’t notice any difference in functionality.
Apply a suction cup to the lower left corner of the display assembly.
Take care not to place the suction cup over the home button.

 

Step 3

Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.
Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices and is held down with adhesive.
Pulling too hard may damage the display assembly. Apply just enough pressure to create a small gap between the display assembly and the rear case.

 

Step 4

 

detaching display from iPhone 6S

 

There is a notch on the underside of the display, just above the headphone jack. This is the safest place to begin prying the phone open.
Place the flat edge of a spudger into the gap between the screen and rear case, directly above the headphone jack.

 

Step 5

 

Removing iPhone 6s display assembly

Twist the spudger to widen the gap between the front panel assembly and the rest of the phone.

 

Step 6

 

Replacing display in iPhone 6s

 

Insert the flat end of the spudger on the left side of the phone, between the display assembly and rear case.
Slide the spudger up the side of the phone to separate the adhesive and pop the clips free.

 

Step 7

Remove the spudger and reinsert it on the bottom edge, where you pried the phone open.

Step 8

Step 9

 

Removing iPhone 6S display

 

Use the suction cup to open the display, breaking the last of the adhesive.
Don’t open the display more than 90º, as it is still connected at the top by three cables that may break if stretched.

 

Step 10

Open the display to about a 90º angle, and lean it against something to keep it propped up while you’re working on the phone.
Add a rubber band to keep the display securely in place while you work. This prevents undue strain on the display cables.
In a pinch, you can use an unopened canned beverage to hold the display.

 

Step 12 Battery Connector

One 2.2 mm screw

Step 15

Remove the following four Phillips screws securing the display cable bracket:

Use the flat end of a spudger, or a fingernail, to disconnect the front camera flex cable by prying it straight up from its socket on the logic board.

 

Step 19

 

Disconnecting digitizer cable in iPhone 6S

 

Use the flat end of a spudger, or a fingernail, to disconnect the digitizer cable by prying it straight up from its socket on the logic board.
When reconnecting the digitizer cable, do not press the center of the connector. Press one end of the connector, then press the opposite end. Pressing in the center of the connector can bend the component and cause digitizer damage.

 

Step 20

 

disconnecting display data cable iPhone 6S

 

Use the flat end of a spudger, or a fingernail, to disconnect the display data cable by prying it straight up from its socket on the logic board.

 

 

Step 21

 

Removing apart iPhone 6S screen

 

Remove the display assembly.

 

Step 22 Battery

 

Removing battery adhesive iPhone 6S

 

Use tweezers to peel back the tips of the two adhesive strips along the bottom edge of the battery.
Use your fingers or blunt tweezers. Be careful when working near the battery; puncturing a lithium-ion battery can release dangerous chemicals and/or cause a fire.

 

Step 23

Pulling battery adhesives out

 

Try to keep the strips flat and unwrinkled during this procedure; wrinkled strips will stick together and break instead of pulling out cleanly.
Slowly pull one battery adhesive tab away from the battery, toward the bottom of the iPhone.
To avoid tearing the adhesive strip, be careful not to snag it against the battery or lower components.
Pull steadily, maintaining constant tension on the strip until it slips out from between the battery and the rear case. For best results, pull the strip at a 60º angle or less.
The strip will stretch to many times its original length. Continue pulling and re-grab the strip near the battery if necessary.

 

Step 24

Battery adhesives in iPhone 6S

Repeat for the second strip.
Hold down the battery as you remove the second strip, or the strip may fling the battery when it separates from the case.
If you removed both adhesive strips successfully, skip the next step.
If either of the adhesive strips broke off underneath the battery and could not be retrieved, continue with the next step below.

 

Step 25

If you successfully removed all three adhesive strips, move on to the next step. Otherwise, you will need to pry the battery from the rear case.
Prepare an iOpener and apply it to the back of the rear case, directly over the battery. Alternatively, you can apply heat using a heat gun or hair dryer.
After about a minute, flip the phone over and use a plastic card to break up any remaining adhesive behind the battery.
Do not insert the card from the right, as prying against the logic board can damage it. Also, be sure to not bend the battery, as doing so can puncture the cell and release dangerous chemicals.

 

Step 26
