Samsung Galaxy A07 4G Battery Replacement

Moderate1 to 2 hours10 steps

If your Samsung Galaxy A07 4G shuts down randomly or struggles to hold a charge, a battery replacement is likely necessary. A swollen battery can also push against the back cover and create a severe safety hazard. This guide will walk you through safely opening the plastic back panel to install a fresh 5000 mAh power cell.

Required Tools

Heat gun or hair dryerSuction cupPlastic guitar picks or pry toolsSmall Phillips screwdriverSpudger (plastic pry tool)Isopropyl alcohol (high concentration)Replacement batteryPre-cut adhesive or double sided electronics tape
  1. 1

    Heat the back cover

    • Apply heat to the edges of the back cover using a heat gun or hair dryer.
    • Keep the tool moving to soften the adhesive without melting the plastic panel.
  2. 2

    Create an opening gap

    • Place a suction cup near the bottom edge and pull up gently to create a tiny gap.
    • Insert a plastic guitar pick into this gap to prevent the adhesive from resealing.
  3. 3

    Slice through the adhesive

    • Slide the plastic pick around the entire perimeter of the phone to cut the adhesive.
    • Be careful not to insert the pick too deeply near the power button to avoid damaging the fingerprint sensor flex cable.
  4. 4

    Remove the back panel

    • Once the adhesive is fully separated, carefully lift the plastic back cover away from the device.
    • Set it aside in a safe place.
  5. 5

    Unscrew the motherboard bracket

    • Locate and remove the small Phillips screws securing the top plastic motherboard cover.
    • Keep these screws organized on a magnetic mat because they must go back into their exact original holes.
  6. 6

    Disconnect the battery

    • Use a plastic spudger to gently pry up the battery connector from the motherboard.
    • Always disconnect the battery first to prevent accidental short circuits during the rest of the repair.
  7. 7

    Soften the battery adhesive

    • Apply a few drops of high concentration isopropyl alcohol along the edges of the old battery.
    • Wait a couple of minutes for the alcohol to dissolve the strong adhesive underneath the cell.
  8. 8

    Pry out the old battery

    • Insert a plastic pry tool under the battery and gently lift it out of the chassis.
    • Never use metal tools or excessive force because puncturing the battery can cause a dangerous fire.
  9. 9

    Install the new battery

    • Clean any leftover adhesive from the frame and apply new double sided electronics tape.
    • Press the new battery firmly into place and reconnect its flex cable to the motherboard.
  10. 10

    Reassemble the phone

    • Reinstall the plastic motherboard cover and secure it with the Phillips screws.
    • Apply fresh adhesive to the edges of the frame and press the back cover down firmly to seal the device.

FAQ

Will I lose my data during this repair?

A battery replacement does not erase your storage. You should still back up your data beforehand just in case an accidental short circuit occurs.

Why is my new battery draining quickly?

New batteries require a calibration period to sync with the software. Charge the phone to 100 percent, leave it plugged in for two more hours, and then use it until it shuts off completely before recharging.

Can I use a metal screwdriver to pry the battery out?

You must absolutely avoid using metal tools near the battery. Puncturing the lithium ion pouch will cause a thermal runaway fire and destroy your phone.

Is the phone still water resistant after this repair?

Opening the device compromises the factory IP54 rating. You must apply a high quality custom adhesive seal during reassembly to restore basic splash resistance.
