When and why you might remove an iPhone battery yourself
You can remove the battery from most iPhones, but Apple does not design them for straightforward home removal — the battery is glued down, and the process requires opening the phone's case. Most people should not attempt this. If your battery is draining too fast, won't hold a charge, or swells visibly, take the phone to Apple or an authorized repair shop instead. They have the right tools, replacement batteries, and insurance if something breaks.
The only common reason to remove a battery yourself is if it has swollen enough to push the screen or back panel away from the frame — a safety hazard. In that case, power off the phone when ready, do not charge it, and get it to a repair shop the same day. A swollen battery can catch fire.
If you are straightforward curious, or you want to understand what is inside your phone, reading this guide is safer than opening it. If you do decide to proceed, understand that you will almost certainly damage the phone, void any warranty, and risk chemical burns from the battery itself.
Key Takeaways
- iPhone batteries are glued to the frame and require heat, prying tools, and careful disconnection of the display cable before removal is possible.
- Apple and authorized repair shops have the correct replacement batteries and tools; home removal almost always damages the phone.
- A swollen battery is a fire hazard and should be taken to a professional when ready, not opened at home.
- If you do remove a battery, wear eye protection and gloves, work on a non-flammable surface, and keep the battery away from water and heat.
- Reassembling the phone and resealing it requires new adhesive strips and a waterproof seal that home tools cannot replicate.
What you need to open an iPhone and reach the battery
Opening an iPhone requires a heat source, prying tools, and a way to disconnect the display. You will need a heat gun or hair dryer set to high heat, a plastic spudger or old credit card to pry with, a small Phillips screwdriver, tweezers, and isopropyl alcohol to soften the adhesive. You should also have a non-conductive surface to work on — a wooden table or cardboard box, not metal — and eye protection in case glass cracks.
The display is glued and also connected to the logic board by a ribbon cable. You cannot remove the battery without first disconnecting this cable, which means the screen must come off first. This is the step where most home repairs fail: the cable is fragile, and pulling too hard tears it. A torn display cable means the screen will not work even after you reassemble everything.
Do not use a metal pry tool or work near water. Lithium batteries can short-circuit and catch fire if punctured or exposed to moisture.
The step-by-step process to remove the battery
Step 1: Power off the phone completely. Do not just lock it. Hold the power button and volume button together until the shutdown slider appears, then slide to power off. Wait 30 seconds.
Step 2: Heat the edges of the display. Use a heat gun or hair dryer on high heat, holding it 4 to 6 inches from the screen. Work around all four edges for 2 to 3 minutes. The goal is to soften the adhesive, not to make the glass hot enough to burn your hand. Test the edge with your finger — it should feel warm, not scalding.
Step 3: Pry up the display carefully. Start at a corner and use a plastic spudger or credit card to lift the screen edge very slightly. Work your way around the perimeter, lifting a little at each point rather than forcing one corner up all the way. The display will separate from the frame, but the ribbon cable is still attached inside.
Step 4: Disconnect the display cable. Once the screen is loose enough to fold back, you will see a small ribbon cable connecting it to the logic board. There is a small black clip or latch holding the cable in place. Use a spudger to gently flip this latch upward, then slide the ribbon cable out of its socket. Do not pull on the cable itself — pull on the connector.
Step 5: Remove the battery adhesive strips. The battery is held in place by two adhesive strips running underneath it, parallel to the long sides. You will see small pull-tabs at the bottom of the battery. Pull these tabs slowly and steadily — they should peel the adhesive strips out from under the battery. If a strip breaks, use isopropyl alcohol and a plastic tool to soften the remaining adhesive and peel it away.
Step 6: Disconnect the battery connector. Before you lift the battery out, there is a small connector on the logic board that the battery plugs into. Use a spudger to gently pry this connector upward to disconnect the battery from power. This prevents any electrical current while you remove it.
Step 7: Lift out the battery. Once the adhesive is gone and the connector is unplugged, the battery should lift out freely. If it does not, there may be more adhesive underneath — use isopropyl alcohol to soften it. Do not force the battery or bend it.
Handling the battery safely during and after removal
A lithium battery can catch fire or explode if it is punctured, bent, or exposed to water. While you are removing it, keep it away from sharp tools, do not bend or twist it, and do not let it touch water. If the battery is visibly swollen, bulging, or has any cracks, do not touch it — leave it in the phone and take the phone to a repair shop when ready.
Once removed, store the battery on a non-flammable surface in a cool, dry place. Do not leave it in direct sunlight, in a car, or near a heat source. Do not try to charge it or use it outside the phone. If you are not installing a new battery right away, keep the old one in a safe place until you can take it to an electronics recycling center. Most cities have drop-off locations for old batteries and phones.
Reassembling the phone and resealing it
Putting the phone back together is not straightforward the reverse of taking it apart. The adhesive strips that held the old battery in place are now stuck to the frame, not reusable. You need new adhesive strips designed for your specific iPhone model — these are sold as battery adhesive kits and cost between $5 and $15. You also need a new waterproof seal around the display, because the original one was damaged when you pried it open.
Install the new battery by connecting its power connector first, then positioning it in the frame and pressing the new adhesive strips down firmly on both sides. Reconnect the display ribbon cable by sliding it into the socket and flipping the black latch down to lock it. Heat the display edges again to reactivate the adhesive, then press it down evenly across the entire frame.
Even with new adhesive, a home reassembly will not restore the phone's original waterproof rating. Water may eventually seep in around the display or battery edges. If water damage occurs later, it will not be covered by warranty.
Why a repair shop is the better choice
Apple charges between $69 and $99 for an out-of-warranty battery replacement, depending on the iPhone model. An authorized third-party repair shop may charge $50 to $80. For that cost, you get a genuine or certified replacement battery, proper tools, a waterproof reassembly, and a warranty on the work. If something goes wrong during the repair, the shop is responsible, not you.
A home repair risks destroying the display, logic board, or both. A cracked display alone costs $200 to $400 to replace. If you damage the logic board while prying, the phone may be unrepairable. The time and frustration of a failed repair often outweigh the money saved by doing it yourself.
Frequently Asked Questions
Can I remove the battery without opening the phone?
No. iPhones do not have a removable battery compartment. The battery is permanently glued inside the frame, and the only way to access it is to open the phone by separating the display from the body.
What if the battery is swollen and I am afraid to open the phone?
Do not open it. A swollen battery is a fire hazard. Power off the phone, do not charge it, and take it to Apple or a repair shop when ready. Tell them the battery is swollen so they can handle it safely.
Can I use super glue or regular adhesive to reassemble the phone?
No. Regular adhesive will not hold the display securely, will not create a waterproof seal, and may damage the phone's components. Use only adhesive strips designed for your specific iPhone model.
How long does a battery removal take at a repair shop?
Most shops complete a battery replacement in 30 minutes to 2 hours, depending on how busy they are. Some offer same-day service if you drop it off in the morning.
What should I do with the old battery after removal?
Take it to an electronics recycling center or a retailer that accepts old batteries — Best Buy, Staples, and most municipal waste facilities have drop-off programs. Do not throw it in the trash or leave it in a hot car.
