Replace your iPhone 4 Battery in 4 Minutes
Replacing the battery of iPhone is wasting time (to leave your iPhone in a shop, come back another day to get it back, usually the replacement may take from 3 to 7 days), money (this costs minimum $50) and knowledge (the company does not provide replacement information).
Now there is quick and easy way to replace the battery of your iPhone paying only 1/3 of the price that is sold in stores. In iphone-battery.com you will find step by step how to replace the battery easily at any iPhone model you have.
If your battery dies quickly or if the charge doesn't last very long in your iPhone, you can very easily replace it yourself. There are only 3 screws you need to remove.
Step 1 - Rear Panel
Before disassembling your iPhone, be sure it is powered off.
Your iPhone 4 rear cover may have either two #000 Phillips screws or Apple's 5-Point "Pentalobe" screws. Check which screws you have and ensure you also have the correct screwdriver in order to remove them.
Remove the two Apple's 5-Point "Pentalobe" or the two Phillips #000 screws next to the dock connector.
Our iPhone 4 Battery Replacement + Tools Kit provides all the tools needed to do the work.
Push the rear panel toward the top edge of the iPhone. (The panel will move about 2 mm.)
Pinch the rear panel with your fingers and lift it away from the iPhone. Alternatively, use a Small Suction Cup.
Be careful not to damage the plastic clips attached to the rear panel.
If you are installing a new rear panel, be sure to remove the plastic protective sticker from the inside of the camera lens and the sticker from the large black area near the lens.
Step 4 - Battery
Remove the single 2.5 mm Phillips screw securing the iPhone 4 Battery connector to the logic board.
Some devices may have two screws, one of which holds down the contact pad which is located above the screw indicated in red in the photo.
Use a plastic opening tool to gently pry the battery connector up from its socket on the logic board.
Pry from the top and bottom of the connector bracket-there isn't as much of an overhang on the sides, and you may damage the connector.
Be very careful to only pry up on the iPhone Battery connector and not the socket on the logic board. If you pry up on the logic board socket, you may break it entirely.
Remove the metal clip covering the antenna connector.
Use the clear plastic pull tab to gently lift the battery out of the iPhone 4.
Do not remove the plastic tab from the iPhone.
You may need to use a plastic opening tool to loosen the adhesive under the battery.
Remove the contact clip from the iPhone 4.
Before reconnecting the battery connector, be sure the contact clip (shown in red) is properly positioned next to the iPhone Battery connector.
Before reassembly, be sure to clean all metal-to-metal contact points on the pressure contact as well as its contact point on the rear panel with a de-greaser such as windex. The oils on your fingers have the potential to cause wireless interference issues.
