Use this guide to replace a worn-out or dead battery in your Samsung Galaxy M31.
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.

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.

Nicely explained Excellent work…. Nice job guys…
Where can I purchase a genuine Samsung battery for the M32?
there's a gasket on the speaker connection to the back that's real easy to damage at step 2
sound leaks into the case without it, if you don't have the exact battery from samsung down to the tenth of a mm thickness the back resonates, there are no replacements (and midframe replacements don't come with it)

the battery i got didn't last long. now that i'm opening it again i see that if you go to the left corner instead of the right corner you avoid the damage that's possible with the speaker surround
