Battery Replacement is one of the most common repairs for OnePlus 7. This repair involves replacing the damaged power component with a new or refurbished part. The process typically takes 30 min - 1 hour and requires moderate skill level.

🔧 Required Tools

🔩 Replacement Parts

What You'll Need

Replacement power part (OEM or aftermarket)
Precision screwdriver set (Phillips #000 or pentalobe)
Opening tools (plastic spudger, suction cup)
Adhesive strips or glue
Clean workspace with good lighting

Step-by-Step Process

Step 1:

Insert and gently push the SIM card ejector tool (or an unfolded paperclip) into the small hole on the left side of the top edge of the phone.

Press gently to eject the SIM tray.

Remove the SIM card tray from the device.

To reinsert the SIM card tray, orient the SIM card with the gold contacts facing up and the notch to the bottom right. Reinsert the SIM card by pressing the card gently into the SIM tray slot.

Step 2:

Use a heat gun to lightly heat the edges of the back to soften the adhesive that connects the back cover to the rest of the frame.

Using a heat gun, hair dryer, or hot plate will make the metal frame rather hot to the touch, so handle it with care.

Be careful not to overheat the device –the OLED display, battery and other internal parts can be damaged by excessive heat. Approximately one minute should be enough to soften the adhesive.

An iFixit iOpener, hairdryer, or hot plate can also be used to heat the edges. See the [link|https://www.ifixit.com/Guide/iOpener+Heating/25705|iOpener Heating guide] for instructions on using the iOpener.

Step 3:

Apply a suction cup to the lower portion of the phone's backing and pull firmly to create a crack between the back cover and the rest of the phone.

Insert a Jimmy tool, opening pick, or [product|IF145-101|plastic card] under the edge of the back cover.

Step 4:

Use a plastic card or Jimmy tool to slice around the phone's seam, cutting through the adhesive.

Step 5:

Remove the phone's back cover.

If you have replacement adhesive strips, remove any remaining adhesive from the device frame using the Jimmy tool.

Step 6:

Use a pair of [product|IF145-020|tweezers] to lift up the piece of black tape covering the laser autofocus and flash flex cable.

Use a pair of tweezers to lift and remove the covering on the laser autofocus and flash flex cable.

Step 7:

Use the flat end of a spudger to disconnect the laser autofocus and flash flex cable.

Step 8:

Peel off the adhesive cover for the new battery cover.

Step 9: Remove upper plate

Remove all 14 screws of the upper plate.

As soon as all screws are removed, you can take it off with a spudger.

One screw is placed underneath a white sticker. You can punch through the sticker with your screwdriver.

All of the screws are the same length, and can be removed with a PH00 bit.

Step 10: Disconnect Battery

Disconnect the battery connector with a spudger.

Step 11:

Grab the tab and gently pull the Battery out.

The Battery is glued on the bottom side.

Step 12: Battery Calibration

After installing the new battery and reassembling your device, calibration is ***highly recommended***. To calibrate the battery, charge the phone to full and allow it to continue charging uninterrupted for 2 hours, let the battery drain fully, and charge it to full without interruption one last time.

This step helps the phone recognize the new battery and to determine its' maximum capacity.
