iPhone 6S Plus Battery Replacement

Before you begin the repair process, discharge the battery below 25%.

A charged smartphone battery can catch fire and explode if punctured.

Caution:

If the battery is swollen, take adequate precautions.

Do not heat the phone. Use isopropyl alcohol around the edges of the back cover to weaken the adhesive.

Use eye and hand protection when working with swollen batteries.

Switch off your device.

You can use a paperclip or a SIM card eject tool.

Insert the tool into the pin hole in the SIM card tray.

Press to eject the tray.

Remove the SIM card tray from the iPhone 6S Plus.

Unscrew the two pentalobe shaped 3.4 mm screws at the bottom of the device.

Note:

When you open the display, it will compromise the device's waterproof seals.

Before you proceed, make sure to prepare replacement seals.

Avoid exposure to liquid if you do not intend to replace the waterproof seals.

Insert the thin metal opening tool into the gap between the display and the frame.

Slide the tool along the edges of the iPhone starting from the bottom.

Remove the clips which hold the display to the metal frame by pulling it slowly slightly away from the phone's top edge.

Swing the display up from the bottom side, using the top side as a hinge to open the iPhone.

Don't fully separate the display at this point because there are still several fragile ribbon cables connecting it to the phone's logic board.

Use an object to prop the display up and keep at approximately 90 degree angle.

Note:

Do not start prying along the top edge of the phone, you risk damaging the plastic clips securing the display.

Remove two Phillips screws from the battery connector bracket

One 2.9 mm screw

One 2.3 mm screw

Remove the battery connector bracket and disconnect the battery

Tip:

Avoid damaging the device by keeping track of the precise positions of the screws during the whole repair.

You should make it a habit to test the replacement parts whenever possible

Connect the replacement battery and turn on the device

Than turn the phone off and disconnect the battery.

There are a couple of very stretchy pull tabs at the bottom of the battery

Start slowly pulling them one by one

When the tabs are removed there is no more glue under the battery

Simply remove the old battery from your device

Now we have to install new adhesive strips.

You can use the same stretchy ones like Apple does or doublesided tape like we do in this repair

Before you insert the new battery, remove the protective film from the battery

Carefully place the new battery on top of the adhesive strips

Moderately press around the battery perimeter to make it bond to the adhesive tape

Connect the battery connector cable to the logic board

Install the metal bracket

Security with two screws removed in step 3

Set the display down to the metal frame and secure the clips

Finish the repair by securing the two pentalobe screws you've removed at the beginning of the repair

Enjoy your device
