Samsung Galaxy S7 Edge Battery Replacement

你所需要的

  1. Samsung Galaxy S7 Edge Battery Replacement, Rear Glass: 步骤 1 中的图像 1,1
    • 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.

    • Heat an iOpener and apply it 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.

    • Once 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 adhere well 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.

    • 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.

    Suction cup does not seem to work.

    Makes it sound ridiculously easy, when in reality you have to be pulling with tons of force while also holding the phone down and on top of that you have to insert the pick in a relatively small amount of time.

    I was getting no where with the iOpener and picks alone, so I followed a YouTube video and used the iOpener as well as a hairdryer. I had to make the first cut in the ahesive with a utility/razor knife, then as soon as I was through the first part I inserted the plastic picks. The back of the phone has to be too hot to touch, ideally all around, so the iOpener alone is not enough.

    Thanks for the above comments. I was also getting nowhere with the iOpener then used a hairdryer on the non-camera end until it was hot to the touch and managed to get a Stanley knife into the gap and lifted enough to get a pick in. Plain sailing from there with patient heating and working the picks in to cut the glue. Eventually success and the back came off.

    • Once you have the pick firmly inserted into the glass, reheat and reapply the iOpener to soften the adhesive.

    • Slide the opening pick up along the side of the phone, separating the adhesive.

    • Go slowly so that the tip doesn't slip out of the seam. If sliding becomes difficult, reheat and reapply the iOpener.

    • 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.

    • Repeat the previous heating and cutting procedure for the remaining three sides of the phone.

    • Leave an opening pick on each side as you continue to the next to prevent the adhesive from resealing.

  6. Samsung Galaxy S7 Edge Battery Replacement: 步骤 6 中的图像 1,2 Samsung Galaxy S7 Edge Battery Replacement: 步骤 6 中的图像 2,2
    • Lift the glass and remove it from the phone.

    • To install a new back cover:

    • Use tweezers to peel away any remaining adhesive from the phone's chassis. Then clean the adhesion areas with high concentration isopropyl alcohol (at least 90%) and a lint-free cloth to prep the surface for the new adhesive.

    • Peel the adhesive backing off of the new rear glass, carefully line up one edge of the glass against the phone chassis, and firmly press the glass onto the phone.

    • If you're reinstalling the old back cover, or using a back cover without adhesive pre-installed, follow this guide.

    • Be sure to turn on your phone and test your repair before installing new adhesive and resealing the phone.

    • If desired, you may reinstall the back cover without replacing the adhesive. Remove any large chunks of adhesive that might prevent the back cover from sitting down flush. After installation, heat the back cover and apply pressure to secure it. It won't be waterproof, but the glue is usually more than strong enough to hold.

    • Remove the twelve 3.5 mm Phillips screws.

    • Use the small notch on the lower left of the upper antenna to pry it out of the phone.

    • Remove the upper antenna.

    • Lift and remove the wireless charging coil from the phone.

    • Lift and remove the loudspeaker from the phone.

    • Use the flat end of a spudger to disconnect the battery connector.

  13. Samsung Galaxy S7 Edge Battery Replacement, Battery: 步骤 13 中的图像 1,1
    • Prepare an iOpener and apply it directly to the battery.

    • Alternatively, apply some isopropyl alcohol under each corner of the battery and allow it to penetrate for several minutes to help weaken the adhesive.

  14. Samsung Galaxy S7 Edge Battery Replacement: 步骤 14 中的图像 1,2 Samsung Galaxy S7 Edge Battery Replacement: 步骤 14 中的图像 2,2
    • Use an opening pick to pry the battery from the bottom.

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

    I used propanol to soften the glue and it worked well. Every time I lifeted the battery a bit (you can hear the glue tearing) I added a few more drops of propanol. Be careful, the heat sink is below the centre of the battery, and I scratched mine a bit as I levered against it.

    • Lift the battery out of the case.

    • Do not reuse the battery after it has been removed, as doing so is a potential safety hazard. Replace it with a new battery.

    • To install a new battery and adhesive, follow this guide.

结论

To reassemble your device, follow these instructions in reverse order.

After completing this guide, calibrate your newly-installed battery.

How.. in the bloody !&&*.. do you use the battery adhesive? Don’t just stop with the removal. Reapplication of the adhesive is an IMPORTANT STEP!

Doug Weber - 回复

Hi Doug,

I’ve written up a short guide for the battery adhesive. You can find it here. It’s now added into the last step. Hope that helps!

1-2 hours…acturally about 30 mins! excellent tutorial

How do you replace battery with the waterproof feature still possible?

Received the package before the delivery date. Very neatly packed and good instructions. Hopefully, the battery will last a while…

Raveena Lal - 回复

How do you reattached the battery connection? The replacement battery won’t fit. I can snap the old battery back in but the new battery is very loose and keeps popping free.

Damion Waltermeyer - 回复

An important question: if i replaced the S7 Edge battery with the S7 one is there any possible issue? I plan to change it as soon as possible but I want to better understand if there can be any issue with the phone.

Andrea Canidio - 回复

I had problems! I came across your post after the repair was complete! You gave more information than the YouTube videos I was using! I struggled removing the battery since it was oversecured with glue! And I kept powering the phone back on by accident pushing the side switch during reassembly! And I got the back of the phone on but not watertight! I feel like I should have used some blue for the back, but didn't have any on hand! But it's together and working! There were better ideas from your article that would have made it less painful for me!

Thank you for a great, clear guide. Great kit from iFixit too including tools and new battery.

The only tricky part was getting the back off. Ditched the iOpener and used a hairdryer (left comment on that section). Once the back was off, took about 30 mins to dismantle, replace the battery and reassemble. Confirmed all working properly then used some B7000 glue to secure the back. Done and phone life extended another few years. Excellent.
