You will need a pentalobe screwdriver and a heat source to remove an iPhone battery safely

Removing an iPhone battery yourself is possible, but the method depends on your iPhone model and whether the battery is glued in place. Most iPhones from iPhone X onward have batteries sealed with adhesive strips rather than screws, which makes removal harder but not impossible. Older models like the iPhone 6, 7, and 8 use a simpler design with fewer barriers. The process takes 30 minutes to an hour if you work carefully and have the right tools.

Before you start, back up your phone data, power it off completely, and discharge the battery to below 25 percent. A partially drained battery is less likely to catch fire if you accidentally puncture it during removal. You will also need a pentalobe screwdriver (the five-pointed star shape Apple uses), a heat gun or hair dryer, plastic pry tools, and tweezers. Do not use metal tools near the battery itself — metal can short the contacts and cause a fire.

Key Takeaways

  • iPhone batteries are glued in place on most modern models, so you will need heat and plastic pry tools to loosen the adhesive strips underneath.
  • A pentalobe screwdriver removes the two screws holding the display assembly, which must come off first to reach the battery.
  • The battery connector sits near the top of the phone and must be disconnected before you attempt to lift the battery out.
  • Puncturing the battery during removal can cause a fire, so work slowly with plastic tools and avoid pressing down on the battery itself.
  • If the adhesive strips tear or the battery cracks, stop and take the phone to Apple or a repair shop rather than risk a battery fire.

Remove the display assembly first

The battery sits behind the display on all modern iPhones, so the screen must come off before you can reach it. Start by removing the two pentalobe screws at the bottom corners of the phone, just above the charging port. These screws are small and straightforward to lose — keep them in a labeled container. On some models like the iPhone 11 and later, you may also need to remove a small metal bracket near the speaker.

Once the screws are out, use a heat gun or hair dryer on medium heat to warm the edges of the display for 30 to 60 seconds. The heat softens the adhesive that holds the screen in place. Start at one corner and gently insert a plastic pry tool — a guitar pick or a plastic spoon works — between the display and the frame. Work your way around the edges slowly, lifting a little at each point. Do not pull the display all the way off yet; it is still connected by a ribbon cable at the top.

When the display is loose enough, carefully flip it up like opening a book, keeping the ribbon cable intact. You will see the battery underneath, along with the connector you need to disconnect. If the ribbon cable is too short to flip the display without straining it, you can disconnect it first by unclipping the small black latch that holds it in place.

Disconnect the battery connector

Before you touch the battery itself, you must disconnect the power connector. This is a small rectangular plug near the top of the phone, usually white or black, with two or three wires attached. Use a plastic pry tool to gently lift the connector straight up and away from the socket. Do not wiggle it side to side — straight up is the correct direction. Once it is disconnected, the battery has no power running to it, which makes the rest of the removal much safer.

Some newer iPhones have a pull-tab or adhesive strip attached to the connector itself. If you see a small plastic tab, pull it gently to disconnect the battery. This is the safest method because it reduces the risk of damaging the connector or the socket on the logic board.

Heat and peel the adhesive strips

iPhone batteries are held in place by two or three adhesive strips that run underneath the battery from top to bottom. These strips are designed to be removable, but they require heat to loosen. Use a heat gun or hair dryer on medium heat to warm the back of the phone for 30 to 60 seconds, focusing on the area where the battery sits. You can also place the phone face-down on a heating pad set to low for a minute or two.

Once the adhesive is warm, look for the small pull-tabs at the top or bottom of the battery. These tabs are usually white, black, or clear plastic and are meant to be gripped with tweezers. Gently pull one tab straight up at a slow, steady angle — do not jerk it. The adhesive strip should peel away from underneath the battery. If the strip tears or breaks, stop and explore more heat. A torn strip is harder to remove completely, and you risk leaving adhesive residue that can damage the battery or the phone frame.

Repeat this process for each adhesive strip. If there is no pull-tab visible, use a plastic pry tool to gently lift one edge of the battery and slide the adhesive strip out from underneath. Work slowly and do not use force. If the battery does not budge after several minutes of heating and gentle prying, stop — forcing it can crack the battery, which is a fire hazard.

Lift the battery out carefully

Once all adhesive strips are removed or loosened, the battery should lift out with gentle upward pressure. Use your fingers or plastic tweezers to grip the battery by its edges, never by the connector or the top surface. Lift straight up slowly and steadily. If you feel resistance, stop and check whether an adhesive strip is still holding it down. Do not pry the battery out with a metal tool or press down on the battery itself — both actions can puncture the battery casing and cause a fire.

As you lift the battery, watch for any remaining wires or connectors that might still be attached. Some models have a small ground wire or a secondary connector near the bottom. Once the battery is fully free, set it on a non-flammable surface like a ceramic tile or glass. Do not place it on fabric, plastic, or wood, which can catch fire if the battery is damaged.

What to do if something goes wrong

If the battery cracks, swells, or starts to smell like chemicals during removal, stop when ready and do not attempt to continue. A damaged battery can catch fire or release toxic fumes. Move the phone to a well-ventilated area or outdoors, and do not try to use it. If the battery is swollen, do not seal it in a bag or container — let it sit in open air. Contact Apple or a certified repair shop and explain what happened.

If an adhesive strip tears and you cannot remove the battery without forcing it, take the phone to a repair shop rather than risk puncturing the battery. The same applies if the battery connector is damaged or if you accidentally disconnect a different cable. Repair shops have the tools and experience to handle these situations safely, and the cost is usually less than replacing a phone damaged by a battery fire.

Frequently Asked Questions

Can I remove an iPhone battery without heat?

You can try, but heat makes the adhesive much easier to work with and reduces the risk of tearing the strips or cracking the battery. Without heat, you will likely need to explore much more force, which increases the chance of damage. A hair dryer on medium heat for 30 to 60 seconds is usually enough.

What if I accidentally puncture the battery?

Stop when ready and move the phone to a well-ventilated area or outdoors. Do not attempt to use the phone or seal it in a bag. A punctured battery can catch fire or release toxic fumes. Contact Apple or a repair shop and describe what happened. Do not try to remove the damaged battery yourself.

Do I need to replace the adhesive strips when I put a new battery in?

Yes. The old strips lose their stickiness once they are removed and cannot be reused. New adhesive strips are inexpensive and come with most replacement batteries. If your replacement battery did not include them, you can buy them separately from electronics retailers or repair shops.

Is it safe to remove an iPhone battery myself?

It is safe if you follow the steps carefully, work slowly, and stop if something feels wrong. The main risks are puncturing the battery or damaging the connector. If you are uncomfortable with the process or something goes wrong, take the phone to Apple or a certified repair shop instead of continuing.

How long does it take to remove an iPhone battery?

Plan for 30 minutes to an hour if you are doing it for the first time and working carefully. Experienced people can do it in 15 to 20 minutes. The heating and adhesive removal steps take the most time. Do not rush — a slow removal is much safer than a fast one.
