Expanded iPhone 3GS Battery

Exbanded_3gs_batteryWe often see this in our workshop. It looks very worrying initially. The screen is often popping out and there is often warping of the logic board.

But in our experience the logic board is fairly hardy and replacing the battery normally sorts things out. The iPhone 3GS pictured above obviously needed a new iPhone 3GS rear case. But to my surprise with a new battery and a new rear case it working like a dream.

You do have to be a little more careful when doing the battery replacement yourself when the battery is swollen. This is because:

  • There is a build up of pressure. So when undoing screw and clips there is an increased possibility of screws or components flying out. I would recommend some sort of eye protection.
  • Due to the logic board often being warped it this situation, it often makes it a lot more difficult to get it out and even more so getting back in. The screw holes can be difficult to line back up for the same reason.
  • There is always a risk when working on electrical devices as so many things can go wrong. If you are in any doubt it probably best to get a professional to do it.

Replacing Your iPhone 3GS Battery

Step 1

Undo the 2 screws a the bottom of the iPhone 3GS using the small Philips (cross head) screw driver.

 

 

 

 

Step 2

Place the screen removal sucker on the lower part of the screen near the home button and slowly lift the screen open. Hinge the screen upwards from the home button, with the hinge point being the upper edge of the screen near the power button, use your other hand to limit how far it opens.

Step 3

Once the iPhone screen is opened you will see 3 ribbons connecting the screen to the logic board. They are labeled 1, 2 and 3. Using a small flat headed screwdriver gently pop the ribbon connectors marked 1 and 2  from the logic board.

 

 

Step 4

Ribbon cable 3 is a little different it has a little locking bar you have gently flick to the upright position, once in the upright open position the sensor ribbon cable 3 can then just be slid out.

 

 

 

Step 5

Next remove the SIM tray by using an Apple SIM card ejector or a paper clip. Then pop off the connectors in order. These are numbered 4 5 6 7.

 

 

 

 

 

Step 6

Now you will need to remove the screws as labeled in the picture. Be careful as the screw holding the camera marked number 1 on the above image has a small metal clip that needs to be removed as well.

The screw marked number 5 is underneath the warranty sticker. This will be damaged during this procedure and the Apple warranty will be voided. This iPhone 3GS is over 12 months old so is no longer covered under the manufacturer’s warranty.

 

Step 7

Gently pop out the camera by levering under the bottom edge of the camera that is attached to the rear of the logic board. Then gently leaver the logic board out from the bottom.

 

 

 

 

 

Step 8

Using the plastic spudger tool and the plastic tab, pry the iPhone battery from the back case. This can be difficult as the adhesive backing on the iPhone battery can be quite strong.

 

 

 

 

 

Step 9

Now place the new iPhone battery into the rear case. The new iPhone battery has a sticker on the back. The protective layer just need to be peeled off. Assembly of the iPhone is just a matter of repeating the above steps in reverse order.

We hope this is a help to all of you iPhone battery replacement DIYers out there.
