Samsung Galaxy Battery Replacement
- AMOLED kept intact
- Swollen cell removed
- PMIC tested
- Genuine cell
Your Galaxy used to last all day. Now it drops 30% before lunch, dies at 40%, or the back glass is starting to lift. We replace the cell safely, with genuine parts, and check whether the battery was ever the real problem.
Galaxy batteries aren't a snap-in part anymore. The cell is glued deep under the screen or back glass, and a swollen one can crack the AMOLED or pop the back panel. We handle that the right way, and if a fresh battery doesn't fix the shutdowns, we already know where to look next.
When you need a battery replacement
- Fast drain, the phone burns through a full charge in a few hours with light use
- Random shutdowns or restarts, often while the battery still reads 30-50%
- Swelling, the screen lifts at an edge, the back glass bulges, or the frame separates
- Won't hold a charge, it climbs to 100% then drops fast, or never reaches full
- Overheating during charging, gaming, or even idle on the desk
- Slow charging that takes hours, or charges only in fits and starts
Honest by default
Every device starts with a $65 diagnostic and a written report, exact cost and timeline before we touch it. The fee applies toward your repair.
Final cost depends on your exact Galaxy model and how it opens, screen-off access and back-off access take different work and adhesive. We never guess. Your $65 written diagnostic confirms the model, checks cycle data and the charging circuit, and applies toward the repair if you move forward.
Genuine cell vs quality aftermarket
| What matters | Genuine cell | Quality aftermarket |
|---|---|---|
| Warranty | 1 year | 1 month |
| Rated capacity | Full factory capacity | Close to factory, varies by supplier |
| Longevity | Longest lifespan | Good, with a shorter horizon |
| Board-level check | PMIC and charging IC tested | PMIC and charging IC tested |
| Best for | Keeping the phone for years | A sensible, lower-cost fix |
The cell is glued deep under the screen or back glass, and a swollen one can crack the AMOLED. We remove it the safe way and tell you which cell your quote uses before any work.
Our battery replacement process
Inspect and handle the cell safely
We check Battery Information and cycle data, then inspect for swelling. A puffed cell is a real fire and pressure risk, we discharge and remove it without puncturing or bending the pouch. If yours is swollen, stop using it and bring it in.
Open the right way for your model
Depending on the Galaxy, the battery sits under the screen assembly or behind the back glass, both set in strong, heat-activated adhesive. We warm the panel evenly and pry with controlled tools so the AMOLED and back glass survive the swap intact.
Install a genuine cell and reseal
We fit a genuine or OEM-grade battery, route the connector cleanly, and replace the perimeter and battery adhesive so water resistance and structural seal are restored, not taped back together.
Calibrate and confirm the real fix
We let the battery cycle, watch the charge curve, and verify the shutdowns are gone. If they aren't, the cell was a symptom, we test the charging IC and PMIC on the board, which is work most shops can't do in-house.

Why bring your Galaxy to WeFixed
We're an independent board-level lab, 11 years of microsoldering, not a kiosk. That matters for batteries, because a Galaxy that keeps shutting down often has a board problem hiding behind a tired cell. We can open the AMOLED panel cleanly, swap the cell safely, reseal it properly, and if the shutdowns persist, test the charging IC and PMIC right here. Honest diagnosis, genuine parts. Walk in at our Clarendon lab or ship it to us tracked from any of the 50 states.
