Introduction

Use this guide to replace a worn-out or dead battery in your Galaxy A50.

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.
You’ll need replacement adhesive to reattach components when reassembling the device.

  1. Insert a SIM card eject tool, a SIM eject bit or a straightened paper clip into the hole on the SIM tray located at the left side of the phone. Press firmly to eject the tray. Remove the SIM card tray.

    • When reinserting the cards, make sure to properly orient them in the tray.

  2. Start by switching off your phone.

    • Heat an iOpener and apply it to the back cover to soften the adhesive.

    • The adhesive of the Samsung Galaxy A50 is very strong. A hair dryer, heat gun, or hot plate may also be used if you aren't able to open the device with the iOpener. Be careful not to overheat the phone—the AMOLED display and internal battery are both susceptible to heat damage.

  3. Insert an opening pick at the bottom of your phone near the USB-C port. If you can't get between the back cover and midframe with your opening pick, you can use a suction handle or strong tape to pull up the back cover to create a gap. Slide the opening pick to the bottom left corner.

  17. The adhesive that holds down the battery in the Samsung Galaxy A50 is extremely strong. Apply some isopropyl alcohol under each corner of the battery and allow it to penetrate for several minutes to help weaken the adhesive.
    • The adhesive that holds down the battery in the Samsung Galaxy A50 is extremely strong.

    • Apply some isopropyl alcohol under each corner of the battery and allow it to penetrate for several minutes to help weaken the adhesive.

    • Alternatively, apply a heated iOpener to the display directly behind the battery for two minutes to help soften the adhesive. Repeat the process as necessary.

  18. Try your best not to deform the battery during this process. Soft-shell lithium-ion batteries can leak dangerous chemicals, catch fire, or even explode if damaged. Do not use excessive force or pry at the battery with metal tools. Insert a plastic card underneath the bottom edge of the battery and carefully slide it underneath the battery. Continue sliding the plastic card underneath the battery to loosen the battery adhesive.

    • Before installing a new battery, remove any remaining adhesive from the phone, and clean the glued areas with isopropyl alcohol and a lint-free cloth.

Conclusion

If possible, turn on your device and test your repair before installing new adhesive and resealing.

Secure the new battery with pre-cut adhesive or double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the device at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place.

To reassemble your device, follow these instructions in reverse order. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

For optimal performance, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least 2 more hours. Then use your device until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.

Great guide.. One tip… ALWAYS make sure to decharge the battery so it have no power before you do anything… example turn on wifi and stream a movie and when phone is out of power you can remove the battery.. never bend it, use heat, use fluid to desolve the glue behind battery.. never cut/damage or bend the battery and use safety glasses just in case. Battery in a mobile phone is NOT a toy

My a50 just got a black screen, I have tried the forced reboot for a couple of time it opened but returns to black screen, now I can't open it with force reboot, is this battery or something else

I have same problem in same time. On the screen, I only have a circle charging sign, but not a percentage of battery charge when it's charging normally. I think the battery's dead.

Hi Allan, It's difficult to remotely identify what's wrong with your A50. Let us know what the reason is if you can figure it out.
