Will Replacing the Charging Port Stop My Phone’s Battery From Swelling?

Replacing a battery normally does not erase the phone’s storage. Your photos and files should remain intact, although any repair carries some risk if the phone is already damaged. If the phone is still cool and stable, prioritize transferring or backing up the most important files without charging it. On many Android phones, Samsung’s transfer tools, Google Photos, or a cable to another device can help, but don’t keep using a visibly swollen phone just to finish a backup.

The technician’s advice about charging to 50% is not something I’d rely on. Limiting the charge does not make a swollen battery safe; the physical damage is already inside the cell. Ask the shop to install the correct replacement battery and inspect the phone for any damage around the back cover and charging circuitry. If the phone becomes hot, starts hissing, smells sweet or chemical, or begins smoking, move away and contact emergency services rather than handling it.

Once the urgent safety issue is handled, set up more than one backup for irreplaceable files. Cloud storage, an external drive, or a trusted computer can each work, and important app data may need to be exported in the app’s own format. But right now, the swollen battery is the priority—not the charging port and not continuing to use the phone normally.

A swollen lithium-ion battery needs to be replaced, not repaired by changing the charging port. Stop charging and using the phone if possible, because a damaged battery can vent, catch fire, or rupture. Keep it away from beds, sofas, paper, and other flammable materials, and take it to a reputable repair shop or an appropriate battery-recycling facility. The charging port may also need attention if it is damaged, but replacing it will not reverse battery swelling.
