Confirm the fault first with a known-good cable and charger and Google's diagnostics app, then order the battery or charging port listed for the exact Pixel model. Treat a swollen battery as a safety issue. Model-matched batteries and charging ports are listed at Parts4Cells.
Is it the battery, the port or the cable?
| Symptom | Most likely cause | First check |
|---|---|---|
| Charges slowly or intermittently | Lint in the port, worn cable or worn port | Clean the port with a plastic pick; try a known-good cable |
| Not charging at all | Charging port, battery or board | Test with a known-good charger; check whether the phone boots on the charger |
| Screen lifting at one edge | Swollen battery | Stop using the phone; handle as hazardous |
| Shuts down at 20 to 30 percent | Worn battery | Check battery health in the diagnostics app |
How do you use Google's diagnostics app?
Google provides the Pixel Repair Diagnostics app on supported phones. It opens by dialing *#*#7287#*#*. Run it at intake and after the repair so both results are on the ticket.
How do you handle a swollen Pixel battery?
- Do not puncture, bend or press on it.
- Use adhesive remover and slow, even pressure instead of prying.
- Keep a fire-safe container and sand or a battery fire extinguisher at the bench.
- Recycle the old battery through a lithium battery recycler. Do not put it in general waste.
What should you test after the repair?
Charge with cable and wirelessly (where supported), check that the charging indicator appears, run the diagnostics battery test, and let the phone charge for a few minutes to watch for heat. Customers remember a repair that runs hot.
How do you keep battery stock fresh?
Lithium batteries age on the shelf too. Buy smaller quantities more often rather than a large batch. Diagnosable batteries and the full battery range can be ordered with no minimum order quantity.
