How Does the OnePlus 7T Battery Replacement Work?
- Battery diagnosis
OxygenOS battery display plus our voltage measurement at the battery module. Below 80 % capacity or above 500 full cycles, we recommend a replacement.
- Carefully opening the display
The OnePlus 7T is opened with a special suction cup, the flex cable is detached, and the panel is fixed on the stand.
- Releasing the battery adhesive strips
The 3800 mAh cell is fixed to the frame with pull tabs. We release it with isopropanol 99 %, never with a screwdriver lever.
- Installing the certified cell
New Li-Polymer cell with identical capacity, 3.87 V nominal voltage, exact-fit form factor. Connector on the mainboard, adhesive on the frame, contact pressure controlled.
- Re-bonding the display and calibration
New seal on the frame, panel bonded under pressure, 30 minutes curing time. Then a full charge for calibration.
- Test and fast-charge check
OxygenOS battery health, voltage curves, charging speed with the original OnePlus Warp Charge 30T power adapter.

How long does the new OnePlus 7T battery last?

Does Warp Charge 30T work on the OnePlus 7T after the battery replacement?

Yes. The flash storage and mainboard are not touched during the battery replacement. OxygenOS, apps, photos, accounts and the Alert Slider mode remain fully intact.
How long does the OnePlus 7T battery replacement take?
60 to 90 minutes of actual working time. With the Vienna pickup service usually back the same working day, at the latest the next day.
My OnePlus 7T is bulging at the back — is that dangerous?
Yes, potentially. A swollen Li-Polymer battery has built up gas pressure — the risk of fire or explosion increases with every charge cycle. Switch it off immediately, send the device to us; dangerous-goods disposal of the old cell is included.
Can I bring my OnePlus 7T in for the battery replacement in Vienna?
Yes, but only at a booked time slot in the 22nd district, there is no open shop. Battery repairs run via online booking plus courier pickup in all 23 Vienna districts. From the provinces, insured shipping in a dangerous-goods box.

Yes. Shipping there and back is done in a UN-approved dangerous-goods box with transport insurance — regularly devices from Graz, Linz, Salzburg, Klagenfurt, Innsbruck and Bregenz.
Is data lost during the OnePlus 7T battery replacement?
No. Flash storage, OnePlus account, SIM and all apps remain untouched. We still recommend a backup — it just makes the work more relaxed.

The OnePlus 7T factory warranty (2 years) expired 7 years ago — there's nothing left to lose. What you get: 6 months Reparo warranty from installation.
My OnePlus 7T charges slower than before — battery or power adapter?
Often both together. An ageing battery throttles the charging current for self-protection, while the USB port may also be corroded. Our diagnosis (25 EUR, waived on repair) separates this cleanly.
Is the OnePlus 7T battery replacement still worth it in 2026?
Yes. 69 € for the replacement versus 159 € for a used device in comparable condition. OnePlus supplies the OnePlus 7T with OxygenOS updates for another 2 years — the device stays secure and usable.
