Introduction

Use this guide to correctly apply replacement battery adhesive strips in any late-model iPhone. Any time you remove the battery, these strips must be replaced. The strips are easily damaged if not applied correctly, so you may want to have a spare set of strips on hand if following this guide for the first time.

The larger iPhone "Plus" models use three strips instead of two, but the procedure is the same.

Before you begin, you should have removed the battery by following one of the guides below. Note: iPhone 5 and earlier models do not use any adhesive strips.

Video Overview

Image 1/3: For iPhone 5s/5c/SE adhesive strips, grab the large blue film backing instead and peel it back slightly to expose a small amount of adhesive near the flat ends of the strips. Image 2/3: Some adhesive strip sets come with no film over the ends, some use a single film, and some use two films as shown here. Image 3/3: Some adhesive strip sets come with no film over the ends, some use a single film, and some use two films as shown here.
  • If present, remove the small plastic film(s) covering the flat ends of the adhesive strips.

  • For iPhone 5s/5c/SE adhesive strips, grab the large blue film backing instead and peel it back slightly to expose a small amount of adhesive near the flat ends of the strips.

    • Some adhesive strip sets come with no film over the ends, some use a single film, and some use two films as shown here.

Notice iPhone 5s/5c/SE users:

The adhesive strips for these models do not look like the current picture above (the pink-side backing extending beyond the blue-side backing). Instead, the blue-side backing extends beyond the pink-side backing.

This means that you have to fold the blue backing just below the black tab. The instructions say to remove the film covering the tabs, but I found it incredibly difficult to remove -- possibly by design -- so I ended up leaving it on, and just cutting off the blue backing below the tabs to expose some of the white adhesion, then just applying the exposed adhesion to the back (blank) side of the battery as seen on Step 5.

I left the black tabs alone, and tucking it into the phone -- not under the batter, but to the bottom of the battery -- just like the original tabs had been done.

I also suggest reviewing the differences of the two sets of strips on iFixit.

They should post separate steps/pictures for the iPhone 5s/5c/SE adhesive strips due to these differences.

Thanks for the feedback! We made some changes to the instructions to clarify the process of applying strips in the 5s/5c/SE models.

I found it easy to align the exposed portion by putting the strips on a flat surface and lowering the lower edge of the battery onto the strips. Therefore I could see that the battery was adhering the correct portion.

I agree it was easier to lay the strips on a flat surface in order to align the battery and the strips properly.

It makes more sense to start peeling from the battery end of the blue strip. I first did it according to the instructions above, and when the blue strip released, it sprung back and its back surface touched the adhesive and wouldn't release, causing the strip to be ruined. (Apparently the back surface of the blue strip is different from the front surface). Starting from the battery end prevents this from happening.

Image 1/1: Since the top edge has no adhesive, you can move the battery freely until it is correctly positioned in the rear case.
  • With the strips facing down, align the top edge of the battery into your iPhone.

    • Since the top edge has no adhesive, you can move the battery freely until it is correctly positioned in the rear case.

    • Make sure the battery cable connector lines up with its socket on the logic board.

It's really important to make sure the battery is flush with the TOP edge of the area it goes into. I read the instructions and noted it said that, but since the photo shows the phone upside down, for some stupid reason, my brain made me lay it flush with the bottom edge, which is the "top" in the photo. When it was time to connect it before closing the phone, the ribbon cable and connector almost did not reach. I had to stretch it a bit, praying that it didn't break.

In my case aligning with the top of the case actually made the connecter just a tad to high and I had to bend the connector wire a bit to get it to connect properly. If I had placed the battery just a bit further down it likely would have fit fine. It might be best to place the battery in without the strips to get a feel for the alignment before adding the strips.

I agree with Sean Kane's recommendation. I ran into the same problem. The instructions make you place it too high.

bvc7g - Reply

agree with Sean and bvc7g. I suggest connecting the connector before laying down the battery, and then laying down the right edge first. This should ensure a neutral position for the ribbon cable.

I had to read these directions thoroughly three times before proceeding as I didn't want to screw it up on the adhesive. Went slow and it worked just fine

patrick knaggs - Reply

I second Mike's comment about placing the battery at the TOP. If you don't, you'll not only have the problem he describes but also there won't be a place to fold the end of the adhesive strip (the pull-tab for next time). You don't want to crowd the home-button/TouchID sensor cable which is right next to it.

Need to possibly redo or add instruction that match what is actually shipped now. The adhesive strips that came with the battery did not look like the one in these directions.

Richard - Reply

I would say jus watch out as you go from step 4 to step 5 - the white adhesive can become slightly detached from the backing as you push it onto the edge of the battery and then around to the back side. Extreme care here! Very good guide and equipment. Galaxy class!

Steve Cottrell - Reply

All was good, aside from the adhesive bunched up when I removed the blue backing and it started to separate from the pink backing. I had to just gingerly make sure it was all straight and kept steady like a heart surgeon until I had it smoothed down as best as possible. It all went well, but I was worried I'd end up with a big stuck ball of white adhesive in the middle of the battery plate, making it all uneven and stupid looking.

What happens if I use a different adhesive than this one?

gleeglee217 - Reply

The iPhone adhesive strips we sell (and the original Apple ones) are special since they have very strong adhesion, but they can be removed easily by pulling on the tabs on the lower edge of the battery. People have had success with our 3M double-sided sticky tape (aka sticker tape), but standard plastic double-sided tape may not have enough strength to hold the battery in place. If you want the strongest adhesive possible, you should use iPhone adhesive strips mentioned above, but if your phone isn't subject to lots of movement, you could get by with some sticker tape.

Thanks for this Jeff! I had a small problem after I followed Step8 and 9 because the battery connector attached to the replacement battery was about 1mm too long and thus aligning the top of the battery caused the connector to be 1mm too high for the socket. I had to bend the 'neck' between the connector and the battery just to align the connector with the socket.

Are the adhesive strips necessary? Mine broke and i put in the battery anyway. Should i purchase a new set and add them in?

dsesnovich - Reply

DO not follow their directions! The color of the film is wrong. Which ever film pulls off the easiest without wrinkling is the one you pull off first then apply it to the battery. Then pull the hardest plastic off next and push the battery to the phone case.

craigmatherly - Reply

If you've wrinkled the strips, it's too late—you'll have to start over with new strips. This guide uses the strips you'll get from iFixit; if you bought different colored strips from somewhere else, you can likely still use the guide, but you'll have to be a little more alert about which side is which.

Jeff Suovanen -

The strips come with a single piece of plastic covering both strips ("double strip cover") on one side, and single pieces of plastic covering each strip individually on the other side ("single strip covers"). If you pull off the single strip covers first, the double strip cover holds the two strips aligned. This makes it easy to position them.

If instead you pull off the double strip cover first, you are left with two individual strips, and have a harder job attaching them. So I think it's clear that you pull off the single strip covers first, regardless of the color of the plastic covering.

I completed this in about 25 minutes it was very straightforward I think of anybody has a problem with any of the instructions or videos they really shouldn't attempt it! You just need to take it slow and don't force anything.

Hi all,

I found an alternative method which, IMHO, works much better than the instructions outlined here. It's also a lot less hassle, worry and problems with lining up things just right. Consider this:

http://cdn.cultofmac.com/wp-content/uplo...

I found it in a November 2013 article on "Cult of Mac" titled "These Are The Secret Little Tools Apple Uses To Repair The iPhone 5s" (http://www.cultofmac.com/252956/genius-b...). As the animation above suggests, you put the adhesive sticky side down first on the iPhone frame where the battery is supposed to go, and then place the battery on top.

The advantage of this method is being able to properly place your battery so that the battery connector lines up perfectly with the logic board. You can also lift/set down your battery in the case multiple times, provided you don't push the battery down on the adhesive. YMMV.

Good luck!

One last note: Folding the pull tabs on the battery in half and trying to get them to fit like the original battery (if you're replacing the old one) is a biatch. If you try the adhesive strip method mentioned above where you put the adhesive down in the iPhone case first, you can lay them flat on the bottom of the case (onto the adhesive) and put the battery over the pull tabs.

You don't get the luxury of pull tabs when you have to change out the battery again, but you have a nice wedge to pry the battery off once you heat the bottom of the case (with a hair dryer or something related).

rskrobe - Reply

Just my opinion, but this method defeats the purpose of buying replacement strips in the first place. If you're going to bury the pull tabs under the battery, you might as well just use regular glue.

Jeff Suovanen -

It's reduculous to charge for these strips. Ifixit should include them with their premium priced batteries.

Mike734 - Reply

We currently include them with all our battery fix kits.

Evan Noronha -

Many of us don't need the kit as we already have all the tools. But everyone ordering a new battery needs the adhesive.

Mike734 -

Fair point. I'll ask our product team what they think of including them.

Evan Noronha -

i changed the battery every things ok now but i have problem whith charg it , 7 hours and the battery got 50% of charg ! its not full

newstyle - Reply

I don't want to put anything sticky and troublesome for replacing anything as I may want to tinker around with it.

Just want to ask if there are any problems if one is not to stick it back on.

Xavier Jiang - Reply

Without adhesive, the battery will be free to rattle around inside the phone. In the short-term it probably won't hurt anything—but if it's a phone you carry with you every day, it could cause issues over time. Maybe try a milder tape or adhesive if you plan to open it up again in the near future. A little double-sided Scotch tape works reasonably well.

Jeff Suovanen -

1. Be very careful not to pry near the top of the battery if the adhesive breaks during removal. It's tempting to use a long plastic probe/spudger at the top of the battery: there is more space there than on the side. Don't. The upper component cable is under the top of the battery. It's easy to catch with whatever you use to pry. I damaged mine, and now the power button, video microphone, flash, and mute switch don't work. (Luckily the volume buttons still do.) Even from the side, be careful not to pry near the top.

2. I put the adhesive on the case first. This left plenty of tab at the end of the adhesive strips, but this didn't help when I found I had a defective replacement. The adhesive tore. It's possible the adhesive is directional, and meant to go on the battery first.

3. Pulling the adhesive to the side is not recommended by 3M for their Command hooks, which use similar adhesive.

4. Replacement adhesive I got was thicker than the original.

Winston - Reply

Some posts suggest putting the adhesive in the case first. This defeats the black plastic tabs on the adhesive. Note Steps 1 & 2 in the instructions. A bit of adhesive above the black plastic strips on one side adheres to the TOP side of the battery. This positions the black plastic strips at the foot of the battery. If you put the adhesive in the case first, the black plastic tabs will be upside down, and you'll have the tabs sticking up.

Look at the black plastic tabs to see which side of the plastic coverings to remove first, Remove the side which has the bit of adhesive first.

Alterations to instructions:

1. Put long part of adhesive on the battery first, then do the black plastic tabs. Alignment of the adhesive is easier.

2. Align the side of the battery with the side of the iPhone case, leaving 1/16"/1mm at bottom, then fold the battery down into the phone. This allows for easy top and bottom alignment. Check that the adhesive will not touch the Upper Component Cable before folding the battery down.
