Samsung Galaxy Z Flip7 FE Battery Replacement

The Samsung Galaxy Z Flip7 FE relies on a 4000 mAh dual-battery system to power its foldable displays. If your device shuts down unexpectedly, drains rapidly, or shows signs of swelling, it is time for a replacement. This guide will walk you through safely opening the phone and replacing both internal battery cells.

1. 1

   Heat the back panels

   • Apply heat to the lower and upper back glass panels using a heat gun.
   • Keep the temperature moderate to soften the adhesive without damaging the internal components.
2. 2

   Pry open the covers

   • Attach a suction cup to the lower back panel and pull gently to create a small gap.
   • Insert a plastic pick into the gap and slide it around the perimeter to slice through the adhesive.
   • Repeat this process for the upper cover.
3. 3

   Remove the protective shields

   • Locate the screws securing the motherboard and sub-board shields.
   • Use your Phillips screwdriver to remove them carefully.
   • Lift the shields away with tweezers to expose the internal connectors.
4. 4

   Disconnect the batteries

   • Safety is critical here.
   • Use a plastic spudger to disconnect both the primary and secondary battery flex cables from the motherboard.
   • This prevents any accidental short circuits during the repair.
5. 5

   Loosen the battery adhesive

   • Apply a few drops of highly concentrated isopropyl alcohol around the edges of both batteries.
   • Allow it to sit for a minute to dissolve the strong factory adhesive underneath.
6. 6

   Extract the old batteries

   • Insert a flat plastic tool under the batteries and gently pry them upward.
   • Never use metal tools or excessive force to avoid puncturing the cells.
7. 7

   Install the new batteries

   • Place fresh adhesive strips into the battery compartments.
   • Seat the new primary and secondary batteries firmly into their respective slots.
8. 8

   Reconnect and reassemble

   • Snap the battery flex cables back onto the motherboard.
   • Reinstall the protective shields and secure them with their screws.
9. 9

   Seal the device

   • Apply new adhesive around the edges of the upper and lower back panels.
   • Press the panels firmly into place and leave the phone under light pressure for an hour to ensure a tight seal.
