Not all iPhone batteries can be removed the same way. The process is very similar, but you will need to use different tools depending on the model. Also note that different models will have slightly different component layouts.
Learn how to remove the battery from iPhone 7 and above, as well as slightly older smartphones in the iPhone 6 series to get an idea of how things might differ between models. If you learn how to remove it from an iPhone, you'll probably also know how to deal with a newer version.
Removing the battery: iPhone 7 and later
Removing a battery from an iPhone may not be an easy task. It's doable at home with the right tools and steady hands, but there's always a risk of damaging your phone. Removing the battery will void your warranty, so it's always best to do so at an authorized Apple Store.
If you choose to do this at home, you will need the following tools:
- Suction cup
- P2 Pentalobe screwdriver
- 2mm screwdriver
- 6 mm screwdriver
- 3mm screwdriver
- 1mm screwdriver
- 1mm screwdriver
- 9 mm screwdriver
While the list of tools sounds scary, the process itself isn't if you approach it with caution. You need to turn off your iPhone first and then warm up the lower part of the case. Attach the suction cup to the screen and gently try to lift the bottom of the screen while using a spudger to open it.
Be careful not to force as you could damage the wiring. Once you've successfully removed all of the adhesive, turn the screen to the right like you would open a book. From there, follow these steps:
- Remove the four three-point screws from the bottom bracket display (look for a connecting ribbon)
- Remove display stand
- Remove the battery connector (the perpendicular plastic strip)
- Tear off the other plastic strip and the gray strip below
- Unscrew the smaller three-point screws holding the bracket to the second display ribbon
- Remove the bracket
- Remove the black plastic strip (the other connector)
- Lift the connector with the spudger and remove it
- Remove screws from barometric vent (black bracket in lower left corner)
- Remove the barometric vent to expose the Taptic Engine connector
- Lift the black plastic connector and remove it
- Remove the screws and remove the Taptic Engine from the case
- Peel off the adhesive strips covering the battery (you may need to reheat the adhesive)
- Remove the battery
Remember to be very careful while doing this. Everything from lifting connectors to peeling strips should be done slowly. When you remove the three bands that hold the battery, you should not risk tearing or creasing. Take it easy and try warming up the adhesive if you feel too much feedback.
Battery Removal: iPhone 6 Series
iPhone 6, 6 Plus, 6S and 6S Plus will require different screwdrivers. Have P2 Pentalobe screwdrivers on hand with 3,6mm heads for the iPhone 6 and 6 Plus and 3,4mm heads for the 6S and 6S Plus phones.
You will also need a suction cup and a spudger to lift the screen and deal with other small components.
Here is what you need to do:
- Turn off your iPhone and remove the screws next to the Lightning port
- Use the suction cup in the lower left corner of the screen
- Lift the screen while holding down the case
- Pry open the case with the spatula and lift the screen to a 90 degree angle
- Look for the battery connector bracket (it's covered with a rectangular metal piece with two screws)
- Use a Phillips #000 screwdriver to remove the screws
- Remove the connector from the motherboard
- Remove the cable holder by first removing the screws (five screws on iPhone 6, 6 Plus, and 6S Plus, and four screws on iPhone 6S)
- Disconnect the camera cable (a large connector with a cable that leads to the screen)
- Remove the remaining connectors
- Separate the screen from the rest of the case
- Peel off the adhesive strips from the bottom of the battery
- Remove the battery
As you can see, whether you have an older iPhone or a new one, the battery removal process is very similar. You may need different tools to handle the different screws and connectors, but some general guidelines still apply.
Never forcibly pull on the screen as you may break the case, cables or connectors, which could render your iPhone inoperable. If the adhesive is a problem, use a remote hair dryer to warm it up.
Always separate all connectors between the display and the screen to separate the case. Uncover the battery by unscrewing the connectors and brackets on top. Use a manual to find out exactly where the battery is on your iPhone model.
Go as slowly as possible through each step, especially when lifting the connectors and removing the battery. Damaging the battery could release dangerous chemicals, not to mention damage your phone. Remember that if you need your battery removed or changed, it's always best to take your phone to an Apple Store or mail it to an Apple Repair Center.
