P9 lite - Replacing the battery

Before the repair, you should switch off your device to avoid short circuits during the repair.

1. Press and hold the standby button until the shutdown dialog appears on the screen.
2. Tap to confirm.

1. Insert your SIM tool into the little hole on the tray to unlock the tray.
2. Remove the tray and any SIM or microSD cards.

The back cover of the Huawei P9 Lite is clipped in all around the display unit.

1. Attach the suction cup relatively far down. Then pull on the suction cup to lift the back cover.
2. Then insert the pick between display unit and backcover and pry them apart.
3. Release the back cover clip for clip around the entire device. If it doesn't work the first time, you can use a second pick or pull it a little harder with your fingers.
4. The back cover is glued to the fingerprint sensor. You can use a heat gun to slightly heat the back cover and soften the glue.
5. Once all the clips are released, you can remove the back cover.

• 9 × Phillips
• Fingerprint sensor
• NFC connector

There is a humidity indicator over one of the screws. You can try to remove it and put it back later, but it usually breaks. So you can simply pierce it with a screwdriver.

1. The cover is secured with Phillips screws. Unscrew all screws and store them safely.
2. Lift up the cover a bit.
Attention: Several cables are attached underneath.
3. The cover is clipped in, once at the camera and once at the side. Gently move the cover to release the clips. Then unfold the cover to the side.
4. Using a spudger, carefully pry off the connector of the fingerprint sensor flex cable.
5. Remove the glued contact of the NFC antenna. If necessary, heat it gently using a heat gun and then carefully pry it off using a spatula.

• Battery connector

Now disconnect the battery to avoid short-circuits.

1. Use a spudger to carefully pry off the connector of the battery flex cable.

• 3 × 2.9 mm Phillips
• 4 × 3.8 mm Phillips

The speaker is connected to the plastic cover of the lower circuit board.

The screws have two different lengths. Store the screws separately to insert them correctly afterwards.

1. Remove the Phillips screws on the plastic cover.
2. Carefully remove the speaker and the attached cover: Slide a thin tool into the opening on the lower edge of the device and pry out the speaker.
3. Now you can take out the speaker.

• Flex cable connector
• 2 × Antenna plug

The black antenna does not need to be removed when replacing the battery.

1. Use a spudger to carefully pry off the plugs on both sides of the antenna cable.

Pry very carefully, or you might tear off the sockets from the PCBs!

2. Remove the antenna cable.
3. Use a spudger to carefully pry off the connectors on both sides of the large flex cable with the arrow.
4. Remove the flex cable.

1. Slowly soften the glue underneath the battery by heating the battery with a heat gun. Never heat the battery directly.
2. Use a broad spudger to carefully lever out the battery from all sides until it comes out easily.

Distribute the hot air evenly and heat the same spot several times instead of risking punctual overheating of the battery. You shouldn't use too much force for the spudger and don't pry from one side only, as this will bend and break the battery.

1. Carefully remove the NFC antenna from the old battery.
2. Stick the NFC antenna to the same spot on the new battery before installing it.

Place the battery into the display unit and carefully press it down to make it stick. Make sure it can't move around.

• Flex cable connector
• 2 × Antenna plug

1. Insert the antenna cable into the diplay unit.
2. Connect the antenna cable plugs to both circuit boards. First position each plug above its socket and carefully press down the plug to make it click into place.
3. Place the large flex cable back between the two circuit boards.
4. Carefully connect the connectors to each circuit board. The two connectors are different. So make sure the arrow points to the mainboard (top).

• 3 × 2.9 mm Phillips
• 4 × 3.8 mm Phillips

1. Insert the plastic cover with the speaker into the display unit and press it down to make it click into place.
2. Fasten the seven Phillips screws. Be careful: They have two different lengths.

• Battery connector

1. Carefully connect the battery flex cable. Make sure the connector is aligned correctly before you press it on. It should click into place. If not, repeat this step.

• 9 × Phillips

1. Place the cover underside facing up on the battery and stick the NFC antenna contact back in place. Use the tab on the contact to position it correctly.
2. Carefully connect the connector of the fingerprint sensor flex cable to the mainboard.
3. Fold the cover onto the mainboard and press it on. Then use the nine Phillips screws to fasten it. The Phillips screws all have the same length.

1. Place the back cover on the display unit and press it down all around to make it snap into place.

1. Insert any SIM or SD cards into the tray.
2. Insert the SIM card tray back into its slot.
