Use this guide to replace a worn-out or dead battery in your Samsung Galaxy A72.
For your safety, discharge the battery below 25% before disassembling your phone. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.
It's possible to remove the battery in the Samsung Galaxy A72 without removing the loudspeaker assembly and the interconnect cable. However the risk of damaging the interconnect cable is high and the removal procedure gets a lot easier with the cable removed.
If you do not replace the adhesive seals when reassembling, your device will function normally, but will most likely lose its water protection.
You’ll need replacement adhesive to reattach components when reassembling the device.
