How does the OnePlus 5T battery replacement work?
- Battery diagnosis
OxygenOS battery readout plus our voltage measurement at the battery module. Below 80% capacity or above 500 full cycles we recommend a replacement.
- Open the display carefully
The OnePlus 5T is opened with a special suction cup, the flex cables are released, and the panel is fixed on the stand.
- Release the battery adhesive strips
The 3300 mAh cell is fixed to the frame with pull tabs. We release it with 99% isopropanol, never with a screwdriver as a lever.
- Install the certified cell
New Li-Polymer cell with identical capacity, 3.87 V nominal voltage, precise form factor. Connector to the mainboard, adhesive to the frame, contact pressure controlled.
- Re-seal the display and calibrate
New seal on the frame, panel bonded under pressure, 30 minutes curing time. Then a full charge for calibration.

OxygenOS battery health, voltage curves, charging speed with the original OnePlus Dash Charge 20W power adapter.

60 to 90 minutes of actual working time. With the Vienna pickup service usually back the same working day, at the latest the following day.
My OnePlus 5T is bulging at the back — is that dangerous?
Yes, potentially. A swollen Li-Polymer battery has built up gas pressure — the fire or explosion risk increases with every charge cycle. Switch off immediately, send the device to us, hazardous-goods disposal of the old cell is included.

My OnePlus 5T charges more slowly than before — battery or power adapter?
Often both together. An aging battery throttles the charging current as a self-protection measure, and at the same time the USB port may be corroded. Our diagnostic check (25 EUR, waived on repair) separates this cleanly.
Is the OnePlus 5T battery replacement still worth it in 2026?
Yes. 59 € for the replacement versus 99 € for a used device in comparable condition. OnePlus still supplies the OnePlus 5T with OxygenOS updates for another 1 year — the device stays secure and usable.
