はじめに

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.
    • 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.
    • 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.

  4. Insert a second opening pick and slide it  from the bottom to the top left corner to cut the adhesive. If you have trouble, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

  7. Remove the back cover.
    • Remove the back cover.

    • After installing the back cover, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.

    Very straight forward and simple replacement to do with the right tools, I used my hot air gun work station so this might have been alot easier for me then someone without one? Hair dryers work too, just in case a hot airgun station is not available to you dont worry you can do this repair without, but some form of heat will make life alot simpler :)

    • 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.

    Pro tip. i Highly recommend that you decharge the battery 100% before you even try to touch the battery. Reason is these kind of batterys do not like to be bend og damaged at all. If the battery is charged and you bend it, it can burst into flames or even explode, if you hear a hissing sound or see smoke instant push the phone away from you.. in worst case it can send out a 30cm burning flame or maybe it just make smoke and nothing happen.. So always drain the telephone of power before you try to remove the battery… Example turn on wifi and make it stream a movie or something until it run out of power is an easy way to do this ;-) No matter what i recommend to use safety glasses just in case. PRO tip.. in general if you repair any machine with a battery disconnect it and make sure it has no power.. A car battery is safe, but the kind in some electronic devices are not.. so make sure battery has no power.!!!!

  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.

  19. Remove the battery. Do not reinstall a damaged or deformed battery, as doing so is a potential safety hazard. Replace it with a new battery.
    • Remove the battery.

    • Do not reinstall a damaged or deformed battery, as doing so is a potential safety hazard. Replace it with a new battery.

    • 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.

終わりに

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
