Typical battery problems on the Galaxy A31
- The Galaxy A31 no longer lasts a workday – you used to easily reach 5–7 hours of screen time
- The device shuts down suddenly at 20–30 % charge and only turns back on once plugged in
- The 5000-mAh battery gets noticeably hot while charging or during 15W fast charging
- The battery percentage jumps in large steps (60 % → 20 %) – calibration is lost
- The back cover bulges in the battery area – visible swelling (a deep-discharge consequence)
- The device no longer starts after a full discharge – the battery is deeply drained
The Galaxy A31 was released in 2020. An ignored fault quickly leads to follow-up damage – see the Galaxy A31 repair overview for all options.
How does the Galaxy A31 battery replacement work?
- Battery diagnosis
Samsung service code *#0228# shows voltage, temperature, cycle count. Capacity below 80 % or > 500 cycles justifies the replacement.
- Open the back cover or display
On the Galaxy A31, models from 2021 have the battery behind the back cover. We warm the adhesive layer to 70 °C and release it carefully.
- Remove the old battery
The 5000-mAh cell is fixed to the plastic frame with pull tabs. We dissolve the adhesive with isopropanol-99, never with a screwdriver pry.
- Install certified 5000-mAh cell
Same nominal voltage (3.85 V), same capacity, same form factor. Connector onto the mainboard, adhesive on the frame, contact pressure controlled.
- Re-sealing
Frame closed with new adhesive. The Galaxy A31 has no factory IP protection – but dust and splash-water resistance is restored.
- Full charge + calibration
First charge at 25 °C to 100 %, then a full discharge and re-charge. The battery gauge is calibrated to the new cell.
Reparo works without customer access – your Galaxy A31 is picked up by courier in Vienna or sent in insured (hazardous-goods compliant shipping box).
Replace the Galaxy A31 battery – price, process and battery life in Vienna
The 5000-mAh battery in the Galaxy A31 lasts 500 to 700 full cycles under normal use – that usually equals 2 to 3 years of everyday use. After that the usable capacity drops below 80 %, which you notice through battery shutdowns at 20–30 %, a hot housing while charging or a bulging housing part. Our Galaxy A52 shows similar aging patterns, but battery cells and prices differ.
Reparo replaces the Galaxy A31 battery in Vienna for a 55 € fixed price – that is about 11 % of the original launch price (500 €). Included are certified 5000-mAh cells, calibration and 6 months warranty. If you also have display problems: see the A31 screen replacement.
Certified cell vs. Samsung original – what goes into the Galaxy A31?
