Introdução

Is your battery running out way too fast? Are you forced to recharge your S7 more than once a day? This guide will show you how to remove the tired old battery in your S7 and replace it with a new one.

Note that the video guide recommends removing the SIM card. This is not necessary, but won't negatively affect repair if you do remove it.

Before disassembling your phone, discharge the battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

If your battery is swollen, take appropriate precautions. Do not heat your phone. If needed, you can use a dropper or syringe to inject isopropyl alcohol (90+%) around the edges of the back cover to weaken the adhesive. Swollen batteries can be very dangerous, so wear eye protection and exercise due caution, or take it to a professional if you're not sure how to proceed.

  1. Opening your phone will compromise its waterproof seals. Have replacement adhesive ready before you proceed, or take care to avoid liquid exposure if you reassemble your phone without replacing the adhesive.
    • Opening your phone will compromise its waterproof seals. Have replacement adhesive ready before you proceed, or take care to avoid liquid exposure if you reassemble your phone without replacing the adhesive.

    • Apply a heated iOpener to a long edge of the phone for about two minutes.

    • You may need to reheat and reapply the iOpener several times to get the phone warm enough. Follow the iOpener instructions to avoid overheating.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the OLED display and internal battery are both susceptible to heat damage.

    I used a heat gun and heated it a little too much. The color of the rear glass is just a sticker on a clear cover. Due to this I tore the sticker off. Now the back cover is see through, which isn’t a bad thing but the repair was for a customer.

    When using the iOpener, you may need more than 30 seconds, especially in compact or low wattage microwaves. Take this slowly, though, and be extremely careful, as it is easy to overheat your iOpener. Remember, you can always heat it up a tad more, but you cannot undo overheating it.

    Jacob Pratt - Responder

    I used an adjustable heat gun and set it to 400 degrees (F). That was enough to seperate the glass without having to worry about exposure times of the heat. The front of the phone was just fine. Just be ready to use a bunch of picks to slide in between because they will be needed this way.

    They should provide two suction cups. Nothing to hold on to.

  2. When the back panel is warm to the touch, apply a suction cup as close to the heated edge of the phone as you can while avoiding the curved edge. The suction cup will not make a good seal on the curved portion of the glass. If the phone's back cover is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.

    • Lift on the suction cup and insert an opening pick under the rear glass.

    • The rear glass can break if you use too much force or attempt to pry with metal tools.

    • Due to the curved glass, you will be pushing up, rather than inserting parallel to the plane of the phone.

    • If you have trouble, apply more heat to further soften the adhesive, and try again. The adhesive cools very fast, so you may need to heat it repeatedly.

    • Optionally, once the pick is inserted, you can add a few drops of isopropyl alcohol into the gap to help weaken the adhesive in the following steps.

    Because of the metal lip around the phone the picks were to thick to get under the glass. Couldn’t get the glue loose enough with the iOpener or the glass lifted high enough with the suction cup despite using a lot of heat and stength on the suction. Ended up having to use a thin piece of metal to get the first separaration. After that the picks are ok to use.

    • Leave the pick in place and grab a second pick as you proceed to the next step. Leaving the pick inserted can help prevent the glue you just separated from re-adhering.

  5. Repeat the previous heating and cutting procedure for the remaining three sides of the phone. Leave an opening pick in each edge of the phone as you continue to the next to prevent the adhesive from resealing.

    • Do not use excessive force or pry at the battery with metal tools.

    • You will be prying against the case directly above the daughterboard and antenna cables. Pry carefully to avoid damaging either of these components.

    • You may need to reheat and reapply the iOpener repeatedly to further soften the adhesive. The adhesive is tough and it may take a few tries to get the pick started under the battery.

    • Try your best not to deform the battery during this process. Soft-shell lithium-ion batteries can leak dangerous chemicals, catch fire, or even explode if damaged.

    Can confirm. I almost had a bad, bad day…punctured the battery with a spudger accidentally

    The connector on the after market battery was a lot harder to press on than the stock one. I struggled to get it connected, so much so that for a moment I though it had the wrong battery connector.

After this is it still waterproof?

Edgar Rodríguez García - Responder

In theory, if you applied the replacement adhesive 100% correctly, it will retain its water resistant properties. However, I would never deliberately expose any device to water, as you can never be completely sure that all the seals are perfectly intact.

Jacob Pratt -

That is actually covered in the video. Did you actually watch it? If water resistant is important to you then what you would do is purchase new gasket material so that after you have opened up the phone and removed all the existing gasket you would apply the new gasket and then finish up and re-seal your phone. As to how water resistant it is after re-sealing the phone all depends on how careful you are and how exact your work is.

marketing major -

Sooooooooo why exactly did Samsung make it impossible to open the phone?

Dan Laemmerhirt - Responder

Because screws are unsightly :P… and repairing your old phone makes you not want to buy a new phone.

Jacob Pratt -

The display is coming off instead of the back panel. Do you have any suggestions if this happens?

scottrape - Responder

How much time do I hit to open back panel? I almost hit 10min using hit gun but It didn't open at all.

Jay - Responder

This was one of the most difficult repairs I have done, but it worked. First off I absolutely could not get anything except a tiny Flathead screwdriver wedged in to the glass to pry it up, which cracked the glass even more than it already was, but thankfully I was replacing the back glass as well. The battery was also glued in unbelievably well, and the battery ended up bending pretty bad when I pried it out, even with a lot of extra heat.

Overall a massive pain in the rear, but I got it all working properly now thanks to the video. I used a Wagner heat gun for this, I don’t think a hair dryer would be sufficient!

Eric Vardin - Responder

I was a bit concerned cause I was using a 300w heat gun instead of the big one in the video, but patience paid off. One tip for anyone else is to make sure the battery is at the TOP of the cutout for it, my connector almost didn’t reach. Nothing broke, phone is on and running, only concern is that I didn’t get all the old glue off, so it might not be water resistant anymore.

Note: Much harder with a screen protector, ended up needing to remove mine and now it’s got dust under it. Luckily, that’s an easy fix, just annoying.

Brian Kurtz - Responder

I wish that tip was in the installation guide as I had the same problem. I used the spudger to slide the battery up a little. It took more force then I would of thought to get the connector back on.

Robert Stoner -

I really wish she would show how to reassemble the phone. How hard is it to work with the new adhesive? I also wonder about the waterproofing after this is complete.

Todd Cooper - Responder

Working with new adhesive can be a bit tricky but there are good do-it-yourself videos that can give you some good tips on how to apply the new gasket before re-sealing the phone

marketing major -

Repair was relatively easy. The problem was with the ifixit-purchased battery which ended up swelling and cracking the rear glass. The battery purchased through them currently lasts 3 minutes off of the charger.

Matthew Martin - Responder

I feel the same way Todd. The video should show you how it goes back together as well, because I bet thats the hard part.

Marc Gale - Responder

I accidentally jabbed the old battery rather hard, pierced it. And then that battery became amazingly very super hot. I’m up where winter is cold, and I put the battery out on my driveway lest it light something on fire. Was still hot as !&&* 20 minutes later. Now I understand why they say we should never put these things in the trash or a landfill cuz they could start a fire.

David Abbott - Responder

I replaced the battery ok and the phone worked ok. Plugging the charger in, the phone reports charging - but it isn’t and the charge decreased until the phone turned off. I put the old battery in, but it is in the same state - phone reports charging, but charge is decreasing. Any ideas on what is damaged or I should replace?

Jim Logan - Responder

Try with new charger and cable

Tomás Rosales -

The guide was good but incomplete. It would have nice to have a little more info on removing the adhesive on the back panel and how to best reapply it. Since this was my own phone I was extra careful but found reapplying the back panel adhesive the hardest part. Not sure if the phone is pushing out in the top left corner or the adhesive is not doing its job. All parts and tools were purchased at iFixit.Com. I used a 800w heat gun and the iSlacks did not work. I cranked up the heat and opened case with my iPhone suction cups. Very cool to know that my apple tools can be used on an Samsung phone…lol…Wow that adhesive was strong. So what do you guys think, should I reheat new adhesive, get it soft then push down firm in that corner to get it to seat better???

Brian - Responder

Just did a successful battery replacement. The back is A LOT more fragile than she makes it look. I anticipated and bought a replacement back. Otherwise the instructions are spot on.

brookman_69 - Responder

Just finished:

I didn’t use a suction cup when taking the back off. I used a flat metal spudger and three plastic hotel room key cards (like credit cards without the bumps). I used a hair dryer and heated the phone for a minute or so. Then, when I was able to stick the spudger in right where the charging port is, I put the card in the spudgers place. After that, I was able to work my way to the left and then inserted another card when I got to the corner. As I went through, I had a pick (shaped a bit less pointy than the tip of a dart) which I would use to “cut” through the adhesive. This worked very well.

I heated it up a bit with the hair dryer and used the spudger and card and got it out without any damage.

The hardest part of this BY FAR is attaching the new battery. The ribbon cable that is attached to the new battery is slightly too short. Therefore, you need to smush the top of the new battery and its really a pain to get it in. Make sure to attach the new battery before putting it into its spot.

ploppalopp - Responder

My employer has about a dozen sales guys in the field, each with an S7. My supervisor agreed to sell me their trade-ins at carrier price. With this guide, I was successful in replacing the battery and can expect about a $150 profit. Thanks iFixit!!!

BTW, I used an iSclack, heat gun, and three picks to get the back off. Did NOT break the back glass!

JONATHAN WHEAT - Responder

An update:

The replacement battery provided to me by ifixit didn’t work. Returned it and tried another and it also didn’t work. Took it to an authorized repair shop (ubreakifix) and it worked. I would suggest that people just go to the repair shop. Saving the $20 just isn’t worth the hassle. Make sure you keep your original battery no matter what.

ploppalopp - Responder

The battery I purchased from ifixit is worse than my original battery! My old battery at least shut off at 1%, this battery shuts off anywhere from 19%-49% !!!!! I didn't do the replacement myself, a friend that owns a shop that does this type of work did it. So I know he did the job right! I'm pretty upset with this battery!!!!!!

Brady Foley - Responder

Hi Brady, sorry to hear about your battery! The battery has a one year warranty, so I suggest contacting customer support to get some help. Good luck with your repair!

Adam O'Camb -

Did you do a battery calibration? Your phone has no way of knowing what the true percentage is until this is completed.

Jacob Pratt -

Yeah the battery that ifixit makes needs to be improved. I highly recommend that you send your phones to samsung if you can deal with not having your phone for 2 weeks. If thats too much, just take them to an authorized repair shop.

andy - Responder

These instructions were pretty thorough. I used a microwaveable rice bag as a warming source. Tried a guitar pick, but too soft and flexible to start the process. Used a carpet knife instead to start, cracked the back (ordered a new one). Then used the pick to slide along edges. To get the battery out I pried and used heat and alcohol. Once I got it lifted enough, I inserted the guitar pick and slid it around under the battery. I’m glad I bought 2 batteries over the Internet from China because 1 was too wide to fit into the phone’s battery frame. The other fit. I would recommend plugging in the connector 1st as I could not quite get it lined up to connect otherwise. Also, do not screw down the battery cover before aligning antenna piece as it has clips that need to align 1st.

cds72365 - Responder

Wow. I'm not feeling good about the battery kit I just bought and am still waiting to receive. I'm almost wondering if I should just forgo the failed new battery and send it back as soon as I get it?

Justin Caskey - Responder

Hi. The battery cycle counter (Phone Info) still shows over 500 cycles after the new OEM battery was installed. Is there any way to reset it?

Thank you

Tomás Rosales - Responder

If I use the applying alcohol method to remove the battery instead of the heating method, could I reuse the battery in another frame?

Charles Albert Martins - Responder

IFixIt should thank Sam. Due to this guide I bought the Battery replacement kit and a full IFixIt pro kit.

Also, Thank you Sam.

Hola buenos días, Si la batería es nueva prueba a agotar carga original e iniciar carga completa y probar se llega a 100, también prueba con otra cargador, asegure de utilizar recambio originales o compatible de alta calidad, Un saludo

henryfiold - Responder

Excellent walkthrough. Thank you

Andrew Gordon - Responder

Very good guide. I used a heating pad on high and the iOpener to heat up the cover. Using the suction cup on its own is difficult. It’s best to order the iSlack along with the kit if you don’t already have one. It makes it a lot easier.

Amin Gangji - Responder

I did it with the iOpener, a hair dryer on level 2 and the other ifxit tools. It took about 5 attempts. Thank you.

Andreas Mehner - Responder

My hand slipped when I was removing the old battery and I saw fire come out of it lol.

No hesitation I threw it all the way across the room like a grenade and was like oh %#*@ lol.

Luckily I was able to remove it without any damage and successfully install a new one/back glass.

Used a old crappy hair dryer lol

Blank - Responder

very good guide. It was very helpful and now I am confident to do it again on another device

joe1234931 - Responder

I can’t seem to calibrate this new battery.

At first, I discharged it, and overnight it only charged to 24%.

Next, I discharged then it would only go to 75%.

Now it won’t charge past 82%.

Any ideas????

I spent so much time and money fixing this battery I want the thing to work!

Ryan Franzese - Responder

Hi Ryan,

When you discharge, and recharge it, does it charge up to the maximum you listed really fast, or does it take a long time?

Arthur Shi -

Despicable of Samsung…

Jesse - Responder

How long does it take to heat up before you can actually remove the back panel? I spent 15 minutes heating up the back with a blow dryer and had absolutely NO luck, even after the back cover was hot to the touch. It seems from watching videos that people had success with getting the back to budge open after just a couple of minutes with a blow dryer. The phone itself is getting hot, I’m applying the heat to the edges as recommended and it just seems nearly impossible. To top it off the back cover cracked when I did try to pry something underneath the cover. Any tips or suggestions would be greatly appreciated.

Eugene Smith - Responder

Hi Eugene,

The hardest part of this repair is the initial opening procedure, and the adhesive on these back covers can be very stubborn! I would suggest trying to focus the heat towards one of the long edges of the back. Once the edge is hot to the touch, apply the suction cup close to the center of the edge and pull with strong, steady force. You can try to loosen the adhesive by pulling on the suction cup repeatedly. Once you get an opening pick into the seam, proceed to heat the rest of the perimeter as you work. Good luck!
