Luckily, replacing the battery on the iPhone 4 requires minimal disassembly. If your battery is swollen, take appropriate precautions.

For optimal performance, calibrate your newly installed battery: Drain battery below 10%, then charge uninterrupted to 100%.

  1. Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
    • Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • Power off your iPhone before beginning disassembly.

    • Your phone's rear cover may have 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 3.6 mm Pentalobe or Phillips #000 screws next to the dock connector.

    • During reassembly, we recommend you replace the 5-point screws with equivalent Phillips screws. Our Liberation Kit provides the tools and screws needed to replace the Pentalobe screws with Phillips screws.

  2. Push the rear panel toward the top edge of the iPhone.
    • 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.

    • Remove the single 1.5 mm Phillips screw securing the battery connector to the logic board (if present).

    • Use the edge of a plastic opening tool to gently pry the battery connector up from its socket on the logic board.

    • Be very careful to only pry up on the 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.

    • Pull up on the exposed clear plastic tab to peel the battery off the adhesive securing it to the iPhone.

    • If the tab breaks before the battery is freed, carefully slide a spudger under the battery tab to release the adhesive. Prying in other places may cause damage.

    • Remove the battery.

    • If your replacement battery came in a plastic sleeve, remove it before installation by pulling it away from the the ribbon cable.

    • Before reassembly, clean metal-to-metal contact points with a de-greaser such as windex. The oils from your fingers have the potential to cause wireless interference issues.

    • Perform a hard reset after reassembly. This can prevent several issues and simplify troubleshooting.

To reassemble your device, follow these instructions in reverse order. For optimal performance, calibrate your newly installed battery: Drain battery below 10%, then charge uninterrupted to 100%.

I actually had the plastic tab break off when I was trying to remove the battery. Any advice?

The plastic opening tools were amazing flimsy- the tips broke off both of them while trying to get the battery out.

The adhesive attaching the battery was very strong and the pull tab actually ripped, though it did not come off.

When I replace my battery for a new one it says accesory not permited or something like that, and I tried with every single battery I found (iphone 4 GSM, Iphone 4s..) is there something I could do? is the battery of iphone 4 CDMA Verizon different from others?

I have a Verizon iPhone 4. Got it the first day Verizon started selling them over 2 years ago. Followed the guide. Completed the task in 10 mins. The battery adhesive must have weakened some. Did not need to use pull tab at all. Just the pry tool along the outer side of battery as mentioned by other users. Thanks ifixit!! Saved me a contract slot. With a family of 4, that is a big savings.

Has anyone had trouble with the battery draining really really <i.e. 10% in 15 min> fast after removing the battery?
