Typical battery problems on the Galaxy A20
- The Galaxy A20 no longer lasts a workday – you used to easily get 5–7 hours of screen time
- The device shuts off suddenly at 20–30 % remaining charge and only turns back on once plugged in
- The 4000-mAh battery gets noticeably hot while charging or during 15W fast charging
- Battery percentage jumps in big steps (60 % → 20 %) – calibration is lost
- The back panel bulges in the battery area – visible swelling (deep-discharge consequence)
- The device no longer starts after a full discharge – the battery is deeply discharged
The Galaxy A20 launched in 2019. An ignored fault quickly leads to follow-on damage – see the Galaxy A20 repair overview for all options.
How does the Galaxy A20 battery replacement work?
- Battery diagnosis
The Samsung service code *#0228# shows voltage, temperature and cycle count. Capacity below 80 % or > 500 cycles justifies the replacement.
- Open the back or display
On the Galaxy A20, the battery on models from 2021 sits behind the back panel. We warm the adhesive layer to 70 °C and release it gently.
- Remove the old battery
The 4000-mAh cell is fixed to the plastic frame with pull tabs. We dissolve the adhesive with isopropanol-99, never with a screwdriver lever.
- Fit a certified 4000-mAh cell
Same nominal voltage (3.85 V), same capacity, same form factor. Connector to mainboard, adhesive on the frame, contact pressure controlled.
- Reseal
Frame sealed with fresh adhesive. No factory IP protection on the Galaxy A20 – but dust and splash-water protection is restored.
- Full charge + calibration
First charge at 25 °C to 100 %, then full discharge and recharge. Battery gauge calibrated to the new cell.
Reparo works without on-site customer access – your Galaxy A20 is picked up by courier in Vienna or sent in insured (a hazardous-goods-compliant shipping box).
Galaxy A20 battery replacement – price, process and battery lifespan in Vienna
The 4000-mAh battery in the Galaxy A20 lasts 500 to 700 full cycles under normal use – usually 2 to 3 years of everyday life. After that, 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 ageing patterns, but battery cells and prices differ.
Reparo replaces the Galaxy A20 battery in Vienna for 55 € fixed price – that is about 18 % of the original launch price (300 €). Included are certified 4000-mAh cells, calibration and 6 months warranty. If you also have display issues: see A20 screen replacement.
Certified cell vs. Samsung original – what goes into the Galaxy A20?

How long does the new Galaxy A20 battery last?

Does the Galaxy A20 have wireless charging?
No, by design the Galaxy A20 has no wireless charging – Samsung omits the Qi coil on the A series to optimise price and weight. It charges exclusively via USB-C at up to 15W.
Does the Galaxy A20 have water protection?
No, the Galaxy A20 has no factory IP rating. During the battery replacement we seal the housing with fresh adhesive against dust and splash water – avoid active submersion.
Is the display damaged during the Galaxy A20 battery replacement?
No, not with us. On Galaxy A20 models with the battery under the display, we warm the adhesive layer in a temperature-controlled way and release it without bending or pressure. If the adhesive strip tears, we renew it at no charge.

Six months on cell and fitting. If the cell loses > 10 % capacity in that time: free re-replacement. Not covered: deep discharge from being left unused for months.
Do I lose the Samsung warranty through the Galaxy A20 battery replacement?
The original Samsung warranty has expired on most Galaxy A20 devices for 2+ years. Reparo warranty 6 months on cell and labour.
