Typical battery problems on the Galaxy A90 5G
- The Galaxy A90 5G no longer lasts a workday – it used to easily reach 5–7 hours of screen time
- The device suddenly shuts off at 20–30 % remaining charge and only turns back on once plugged in
- The 4500-mAh battery gets noticeably hot while charging or during 25W 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 deep-discharged
The Galaxy A90 5G launched in 2019 as the first 5G A-series model in 2019. An ignored fault quickly leads to follow-up damage – see the Galaxy A90 5G repair overview for all options.
How does the Galaxy A90 5G battery replacement work?
- Battery diagnosis
The Samsung service code *#0228# shows voltage, temperature and cycle count. Capacity below 80 % or more than 500 cycles justifies a replacement.
- Open back cover or display
On the Galaxy A90 5G the battery sits behind the back cover on models from 2021 on. We warm the adhesive layer to 70 °C and release it carefully.
- Remove old battery
The 4500-mAh cell is fixed to the aluminium frame with pull tabs. We dissolve the adhesive with isopropanol-99, never with a screwdriver pry.
- Install certified 4500-mAh cell
Same nominal voltage (3.85 V), same capacity, same form factor. Connector to the mainboard, adhesive to the frame, controlled contact pressure.
- Reseal
Frame closed with fresh adhesive. The Galaxy A90 5G 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 recharge. The battery gauge is calibrated to the new cell.
Reparo works without customer access – your Galaxy A90 5G is picked up by courier in Vienna or sent in insured (hazardous-goods-compliant shipping box).
Replacing the Galaxy A90 5G battery – price, process and battery life in Vienna
The 4500-mAh battery in the Galaxy A90 5G lasts 500 to 700 full cycles under normal use – usually around 2 to 3 years of everyday life. After that the usable capacity drops below 80 %, which you notice from battery shutdowns at 20–30 %, a hot housing while charging or a bulging case part. Our Galaxy A52 shows similar ageing patterns, but the battery cells and prices differ.
Reparo replaces the Galaxy A90 5G battery in Vienna for a €69 fixed price – about 10 % of the original launch price (€700). Included are certified 4500-mAh cells, calibration and 6 months warranty. If you also have display issues: see the A90 5G screen replacement.
Certified cell vs. Samsung original – what goes into the Galaxy A90 5G?
For the Galaxy A90 5G we fit certified 4500-mAh battery cells that match the original Samsung specifications: 3.85 V, the same charge curve. Original Samsung service packs are only available through Samsung service centres – our aftermarket cells measurably last just as long. Price comparison of all battery repairs: Samsung overview.
