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

For optimal performance, after completing this guide, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least two more hours. Then use your iPhone until it shuts off due to low battery. Finally, charge it 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. The panel will move about 2 mm.

    • Remove the metal clip covering the antenna connector.

  7. 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.

    • 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.

Conclusión

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow the above steps in reverse order.

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

SOCRATES8181 - Contestar

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?
