Use this guide to replace the battery. Warning: This guide requires soldering.

  1. The iPod Touch 4th Generation front panel is attached to the rear case by adhesive. The use of a heat gun to soften the adhesive is highly recommended.
    • The iPod Touch 4th Generation front panel is attached to the rear case by adhesive. The use of a heat gun to soften the adhesive is highly recommended.

    • With the heat gun set on "low", begin heating the lower portion of the Touch near the home button.

    • It is suggested to heat the desired portion in a circular motion pattern to evenly dissipate the amount of heat throughout the device.

  2. Beware, as the Touch will be very hot. It may be helpful to hold it with a towel while prying. Insert the edge of an iPod opening tool between the front glass panel and the  plastic bezel near the home button.
    • Beware, as the Touch will be very hot. It may be helpful to hold it with a towel while prying.

    • Insert the edge of an iPod opening tool between the front glass panel and the plastic bezel near the home button.

    • Do not try to pry between the plastic bezel and the steel rear case.

    • Pry the bottom edge of the front panel upward, being careful not to bend the glass excessively.

    • If it is too difficult to pry up the front panel assembly, reheat it and try again.

  3. When there is enough room to grab the bottom edge of the front panel, lift it away from the body of the Touch to peel up the adhesive along its left and right edges.
    • When there is enough room to grab the bottom edge of the front panel, lift it away from the body of the Touch to peel up the adhesive along its left and right edges.

    • If the adhesive is too difficult to separate, use a heat gun to soften it before proceeding.

  4. Due to the construction of the 4th generation Touch, the digitizer cable cannot be disconnected until the logic board is removed. Use extreme caution when handling the front panel assembly, as it is attached to the rest of the Touch by the very delicate digitizer cable. Also, the display data cable is very short and is connected to the logic board near the top of the front panel assembly. If it does not become disconnected while freeing the top edge of the front panel assembly, be sure to disconnect it with an iPod opening tool before rotating the front panel assembly out of the Touch.

    • Insert the edge of an iPod opening tool under the steel mid plate near the bottom left corner of the Touch.

    • Pry upward to separate the plate from the adhesive securing it to the plastic inner case.

    • If the plate is still attached to the logic board re-warm the area to loosen the adhesive, then separate the plate from the logic board using the opening tool

    • Use extreme care, the speaker is under the area shown in photo. It is connected with very thin and short wires.

    • There is a very thin ribbon cable here that connects the volume and power buttons to the logic board. Try to work around this area like shown so not to rip the cable. Be sure to hold down this cable when lifting the plate. It could stick to the plate due to residual glue. It is extremely fragile.

    • This cable will tear very easily if you are not careful.

    • There is also adhesive under the area shown in red.

  8. Slightly tilt the steel mid plane to dislodge it from the rear case. Be careful not to tear the piece of copper tape connecting the rear-facing camera to the steel mid plane.

  24. In the next few steps, you will desolder the three battery solder joints on the logic board.
    • In the next few steps, you will desolder the three battery solder joints on the logic board.

    • Prior to desoldering the 3 leads, there may be some silicon/glue covering them. Remove as much as possible with a plastic or metal spudger (if metal, be extremely careful not to bridge the connections) before applying soldering tip to points.

  25. The battery on the fourth generation Touch is attached via solder pads with small holes that go through the battery ribbon cable and attach to flat pads on the face of the logic board. In this step, you will heat each solder pad individually while using a metal spudger to pry it up from the logic board. DO NOT bridge the connection between the solder pads both on the board and on the ribbon cable with your spudger. Shorts have the potential to ruin the logic board. Beware of overheating the board and the cable. Only hold the tip of the iron against the pad long enough to let the solder melt. Excess heat buildup has the potential to ruin the logic board or melt the ribbon cable.

    • Place the strip of tape over the end of the battery ribbon cable to cover two of the solder pads and hold the contacts down against the logic board.

    • Heat the rightmost contact until the solder below melts, then apply a small amount of solder to the contact, allowing it to flow through the two holes in the cable and down to the logic board.

    • Do not apply too much solder. The amount required for a proper bond is miniscule.

    • As soon as the solder has flowed into the joint, remove both the solder and the iron.

  29. Move the piece of tape so that it no longer covers the remaining two leads. If you are satisfied with the position of the cable relative to the pads on the board, proceed. If not, de-solder the first connection and try again.

Where do i get the best quality battery?

Dave - Ответить

Did it! Now screen is a bit funky when I press on the sides of the iPod. Although all seems good :)

Thanks iFixit!

Philipp Boulanov - Ответить

I had a similar problem when pressing on the center button. Turns out it was too much solder on the battery connector. I had to disassemble again and used some solder wick to lower the solder blobs. I suspect that the back plate must not be completely flat for you.

Joshua Belcher -

I followed this guide to the letter but the new battery only has half a charge and will not take a charge when plugged in. Any thoughts?

Bill Lee - Ответить

To clarify, does the battery show as charging when plugged in? If so, will it go from no/low charge back up to half charge? If this is the case, I would contact whoever sold you the battery and ask for a replacement.
