Introduction

Use this guide to remove or replace the battery on your Samsung Galaxy Note10+ 5G.

If your battery is swollen, take appropriate precautions.

For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.

This guide uses steps written for the non-5G Note10+. Some images in this guide may show minor discontinuities. They shouldn’t affect the overall guide procedure.

  1. Completely power off your phone before you begin disassembly.
    • Completely power off your phone before you begin disassembly.

    • Prepare an iOpener and apply it to the left edge of the rear cover for one minute.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.

  2. Apply a suction cup to the heated edge of the rear cover, as close to the edge as possible. If your rear cover is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken cover. Pull up on the suction cup with strong, steady force to create a gap between the rear cover and the frame.

    • Pull up on the suction cup with strong, steady force to create a gap between the rear cover and the frame.

    • Depending on the age of your phone, this may be difficult. If you are having trouble, apply more heat to the edge and try again.

    • Insert the point of an opening pick into the gap.

  3. Slide the opening pick along the left edge towards the bottom left corner to slice the adhesive. Don't insert the opening pick more than halfway into the phone or you risk damaging internal components. Leave the pick inserted in the bottom left corner to prevent the adhesive from re-sealing.
