How To Change A Battery Ipod 4th Gen

Introduction

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

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 instance past agglutinative. The use of a heat gun to soften the agglutinative is highly recommended.
With the oestrus gun set on "low", begin heating the lower portion of the Touch virtually the domicile button.
It is suggested to heat the desired portion in a circular motion pattern to evenly dissipate the amount of heat throughout the device.

Beware, as the Touch will be very hot. It may be helpful to hold it with a towel while prying.

Beware, as the Touch volition exist very hot. It may be helpful to hold it with a towel while prying.
Insert the edge of an iPod opening tool betwixt the front glass panel and the plastic bezel near the home button.
Do non attempt to pry between the plastic bezel and the steel rear case.
Pry the bottom edge of the front panel upward, beingness careful not to bend the glass excessively.
If it is too difficult to pry up the front panel assembly, reheat it and try once again.

When there is enough room to grab the bottom border of the front panel, lift it away from the torso of the Touch on to peel up the adhesive along its left and right edges.
If the adhesive is too difficult to separate, employ a heat gun to soften it before proceeding.

Due to the construction of the fourth generation Touch, the digitizer cable cannot be disconnected until the logic board is removed. Utilize extreme caution when handling the front console assembly, as it is attached to the rest of the Touch past the very delicate digitizer cablevision.
Besides, the display data cable is very short and is continued to the logic board near the top of the front panel assembly. If it does not become disconnected while freeing the pinnacle border of the front panel assembly, exist sure to disconnect information technology with an iPod opening tool before rotating the front panel assembly out of the Touch on.
Advisedly pull the top of the front panel assembly away from the adhesive property information technology to the Bear on, minding the short digitizer cablevision connecting the ii components.

Remove the following viii Phillips #00 screws:
1 3.5 mm Phillips screw
Ii 3.0 mm Phillips screws
One two.3 mm Phillips screw
1 2.4 mm Phillips screw
Three two.0 mm Phillips screws

Use the edge of an iPod opening tool to pry the sparse steel comprehend up from the rear-facing camera.
Note the small spring located virtually the bezel next to the camera (highlighted in yellow).
Remove the steel encompass from the iPod.

Insert the edge of an opening tool under the steel mid plate about the bottom left corner of the Bear upon.
Slowly pry upwardly to split up the plate from the agglutinative securing it to the plastic inner instance.
If the plate is withal fastened to the logic board, re-warm the surface area to loosen the adhesive, and so slowly split the plate from the logic board using the opening tool.
At that place is a sparse, frail ribbon cable underneath the plate. As you pry the plate up, be very careful not to rip the cable.
This cable may stick to the plate and will tear very easily if you're not careful. Piece of work slowly and be careful not to strain the cable.

Slightly tilt the steel mid plane to dislodge it from the rear case.
Be careful non to tear the piece of copper record connecting the rear-facing camera to the steel mid plane.
Lift the steel mid plane up off the rear instance and peel off the piece of copper tape stuck to the rear-facing photographic camera.

Use an iPod opening tool to pry the headphone jack connector up and out of its socket on the logic board.

Remove the unmarried 2.6 mm Phillips screw securing the headphone jack associates to the rear instance.
The screw is at a xc caste angle. Make certain to remove it at such an angle.

Utilise an iPod opening tool to gently lift the edge of the headphone jack nearest the bombardment out of its recess.
Remove the headphone jack from its housing within the rear case.

Remove the following three screws near the top edge of the logic board:
One 2.0 mm Phillips spiral
Two ii.3 mm Phillips screws

Use the border of an iPod opening tool to gently pry, but not remove, the rear-facing camera away from the rear case.
Do not attempt to remove the rear-facing camera yet.

Use an iPod opening tool to slightly lift the edge of the logic board adjacent to the battery enough to grab it with your other mitt.
Practice not excessively curve the logic board, equally information technology is very thin and frail.
Exist very careful not to lift also much as the volume control ribbon cable is still continued and will tear very easily.
While gently lifting the logic board with ane hand, use an iPod opening tool to lift the logic board near the copper tape at the logic lath's top edge.
The logic board will be lifted fairly when the last display assembly connector has cleared the elevation edge of the rear case.

With a plastic opening tool, gently pry the iPod's speaker out of its recess in the outer case.
Do not try to completely remove the speaker. It is withal soldered to the underside of the logic lath.
Allow the speaker to rest above the battery so that you tin can proceed with battery installation.

In the next few steps, you will loosen the agglutinative from underneath the battery, the logic board, and the frame under the battery. Do this slowly, carefully, and evenly. Have care non to puncture the battery or bend the logic lath.
Use a plastic opening tool to pry up the adhesive around the iii exposed edges of the battery.
Practice not try to pry the battery out, just start loosening the adhesive.

Later on the edges of the bombardment are loosened, begin prying up the edge of the logic lath. Start at the top and piece of work your way down the side of the board.
To prevent bending/breaking the logic board, exercise not endeavour to remove the logic board, withal. The dock connector is still embedded in the frame. Again, you lot are only trying to loosen more of the adhesive.

With a plastic opening tool, advisedly push the dock connector out of its outer case recess. Work each corner evenly until the connector comes costless.
Since the dock connector is attached to the logic board, pushing information technology out of the case may cause the logic lath to begin to flex. Take extra care non to permanently warp the board.

Once all of the adhesive is freed from under the logic board/bombardment assembly, elevator the assembly upwardly from the side and carefully rotate it over to access the underside of the battery.
The logic board is still attached to the rear instance. Do not endeavour to completely separate the associates, or you will rip this ribbon cable.

Grip the copper shield located on the bottom of the battery with one paw while firmly holding the bombardment with the other.
Carefully skin the copper shield up off the battery.
Practise not rapidly peel the copper shield. Doing so may cause irreversible damage to the battery.
When installing a new battery, the copper shield must be as flat every bit possible. Otherwise the ruffled shield volition add to the thickness of the battery and LCD combined.

If necessary, utilize a plastic opening tool to peel the piece of yellowish kapton tape located virtually the bottom of the battery.

At this betoken, the battery should only be attached to the logic board by a single cable.
Rotate the battery up and away from the logic board.
Flip the assembly over to reveal the battery solder points.

In the next few steps, you lot will desolder the 3 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, exist extremely careful not to bridge the connections) earlier applying soldering tip to points.

The battery on the quaternary generation Touch is fastened via solder pads with small-scale holes that go through the battery ribbon cable and attach to flat pads on the face up of the logic board. In this stride, yous will heat each solder pad individually while using a metal spudger to pry it upward from the logic board.
DO NOT span the connection between the solder pads both on the board and on the ribbon cable with your spudger. Shorts take the potential to ruin the logic board.
Beware of overheating the lath and the cable. Merely hold the tip of the atomic number 26 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.
Start working from the outside of the bombardment ribbon cablevision. Oestrus the outermost solder pad while gently prying up from under the ribbon cable to free it from the lath. Echo this process for each of the two remaining pads, working from the exterior in.

At this indicate, the bombardment should be free from the logic board.
Remove the sometime battery from the logic lath and set it aside.

Next, use the tip of a soldering iron to flatten out the solder on the logic board solder pads. The pictures show a 'before' and 'later on' shot.
Call up not to heat up the pads likewise much.

Place the new bombardment in place and marshal the far contact with the outer solder pad. Apply a pocket-size strip of electrical tape to agree the cable against the solder pads.
Installing the bombardment upside down (with the cable facing up) will destroy the logic board.
Identify the strip of record over the finish of the battery ribbon cable to embrace two of the solder pads and hold the contacts downwardly confronting the logic lath.
Rut the rightmost contact until the solder below melts, then apply a pocket-size corporeality of solder to the contact, allowing information technology to flow through the two holes in the cable and down to the logic board.
Do not apply also much solder. The amount required for a proper bond is miniscule.
As before long as the solder has flowed into the joint, remove both the solder and the fe.

Move the piece of tape then that it no longer covers the remaining two leads. If y'all are satisfied with the position of the cablevision relative to the pads on the lath, proceed. If not, de-solder the offset connection and try again.
Solder the two remaining pads to the logic board, existence mindful of overheating the cable or board.
