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.

Galaxy A50 Battery

Step 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.

Step 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.

Überhitzen das Gerät nicht, das AMOLED-Display und der Akku sind sehr hitzeempfindlich.

Nur ein kleiner Tippfehler-Hinweis: (Überhitze das Gerät nicht)

OK, korrigiert. Das kann übrigens jeder machen, iFixit ist ein Wiki.

how long should the heat pack be used for?

David Hall -

The heat pack is in the wrong position in photo - the glue that you are heating is actually all around the edge of the phone!

Step 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.

It would be much better to attempt the opening from the top of the phone as there is a delicate flex PCB antenna at the bottom just where you stick the pick in that can get damaged.

Wish I would have read your comment before, since I destroyed that cable while opening my phone... It's a cable for microphone, speaker and headphone jack. Replacing it was a real pain because it's glued but luckily I was able to find a spare.

Step 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.
Leave the opening picks in place to prevent the adhesive from resealing.

Step 5

Insert a third opening pick under the top left corner of the back cover.
Slide the opening pick along the top edge of the phone.
Leave the opening pick in the top right corner to prevent the adhesive from resealing.

Step 6

Insert a fourth opening pick under the top right corner of the back cover.
Slide the tip of the opening pick along the side of the phone to the bottom right corner to cut the adhesive.
Leave the opening pick in the bottom right corner to prevent the adhesive from resealing.

Step 7

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 :)

Step 8

Remove the 13 Phillips #00 screws (4 mm length).

To separate the screen from the mid-frame a few pointers I picked up from a video
1. use a hard pry tool such as iFixit Opening Tool
2. start on a long side about quarter way down from corner
3. work around the frame careful not hook the button assembly

Code Jason -

Step 9

Insert an opening pick between the display and the midframe at the bottom of your phone above the USB-C port.
Slide the pick along the bottom edge to release the clips.

I found it much easier to get the pick in at the sim tray. Down at the usb port the subframe is quite sturdy and just won't give.

Step 10

Continue sliding the pick along the left edge of the phone to release the clips.

Step 11

Slide the opening pick along the top edge.

Step 12

Slide your opening pick along the right edge towards the bottom right corner.

Step 13

Make sure you free all the clips securing the midframe.
Separate the midframe from the phone.

Step 14

Use a spudger to disconnect the battery by prying the connector straight up from its socket.

Step 15

Use the flat end of a spudger to pry up and disconnect the interconnect and display flex cables from the motherboard.

Step 16

Use the flat end of a spudger to pry up and disconnect the charging port and display flex cables from the daughterboard.

Step 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.
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.!!!!

Step 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.

If youve been struggling with this part for the past 30 mins (just like me), i recommend using the blue thingies from the steps where you removed the screen and backplate, worked immediately

Step 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.
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%.

Take your e-waste to an R2 or e-Stewards certified recycler.

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

Teşekkürler. Çok açıklayıcı ve anlaşılır biçimde hazırlanan değerli bir rehber olmuş. Gerçekten başarılı.

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

allan_heyz - 07/06/21

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.

inaumoski - 08/06/21

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.

Adriana Zwink -

Perfecte handleiding! ik heb deze gevolgd en binnen een uurtje was mijn telefoon voorzien van een nieuwe batterij.

Kleine opmerking nog, bij de stappen 9-13 moet je de openingsplectrum wel een beetje schuin naar beneden houden zoals duidelijk te zien is in stap 9/ Als je hem iets vlakker houdt zoals ik eerst deed dan gaan de klemmetjes niet los.

Gertjan Evertse -

Hi @Gertjan, we’re happy to hear that your smartphone is up and running again. Thanks for your feedback!

Adriana Zwink -

Can I use iPhone adhesive strips to hold down the new battery?

Thanasis Dakakis -

Sure, you can use them for your Samsung as well. Good luck with your repair :).

Adriana Zwink -

Zdravím jaké lepidlo můžu použít k nanesení pod baterku?

Bob Bobek -

Clear and informative instructions that are well illustrated. They enabled me to make a successful replacement of the battery. Thank you!

الله يبارك ماشاء الله

KADER ARAIBIA -

i had the same problem too, i replace it with a new battery and now i got a new problem that give a temperature icon when i connect it to the charger ???

michel Claes -

When refitting the back cover, what adhesive is used? Step 19 says to remove any remaining adhesive -- does that include whatever was used to hold the back cover on originally?

Mike L -

Yes, I bought pre-cut adhesive with the new battery. Removing old adhesive was really a pain in the a**. If anyone have any tips on how to remove old adhsive easily, I'd be happy to hear. i used IPA and lint free cloth, but it was a ton of scrapping and a lot of mess.
