- OxygenOS reports significantly reduced capacity in the battery settings
How does the OnePlus 7 Pro battery replacement work?
- Battery diagnosis
The OxygenOS battery display plus our voltage measurement at the battery module. Below 80 % capacity or above 500 full cycles we recommend the replacement.
- Carefully open the display
The OnePlus 7 Pro 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 4000 mAh cell is fixed to the frame with pull tabs. We loosen it with 99 % isopropyl alcohol, never with a screwdriver as a lever.
- Install the certified cell
New Li-Polymer cell with identical capacity, 3.87 V nominal voltage, exact form factor. Connector on the mainboard, adhesive on 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.
- Test and fast-charge check
OxygenOS battery health, voltage curves, charging speed with the original OnePlus Warp Charge 30W power adapter.

How long does the new OnePlus 7 Pro battery last?
With normal use the replacement battery manages 500 to 700 full cycles with at least 80 % capacity — that corresponds to roughly 2.5 to 3.5 years of everyday use.
Does Warp Charge 30W work on the OnePlus 7 Pro after the battery replacement?

Does OxygenOS stay unchanged on the OnePlus 7 Pro 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 7 Pro battery replacement take?
60 to 90 minutes of pure working time. With the Vienna pickup service usually back the same working day, at the latest the following day.
My OnePlus 7 Pro 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 rises with every charge cycle. Switch it off immediately, bring the device to us, and dangerous-goods disposal of the old cell is included.
Can I drop off my OnePlus 7 Pro 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.

Shipping from the provinces: is the OnePlus 7 Pro battery replacement safely possible?
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 7 Pro battery replacement?
No. Flash storage, OnePlus account, SIM and all apps remain untouched. We still recommend a backup — it makes the work more relaxed.
How long is the warranty on the new OnePlus 7 Pro battery?
Six months Reparo warranty on cell and installation. If a defect occurs during this time: free re-replacement, without a second diagnostic fee.
Do I lose the OnePlus warranty on the OnePlus 7 Pro through the battery replacement?
The OnePlus 7 Pro factory warranty (2 years) expired 7 years ago — there is nothing left to lose. What you get: 6 months Reparo warranty from installation.
My OnePlus 7 Pro charges slower than before — battery or power adapter?
Often both together. An ageing battery throttles the charging current to protect itself, while at the same time the USB port may be corroded. Our diagnosis (25 €, waived on repair) cleanly separates the two.
Is the OnePlus 7 Pro battery replacement still worth it in 2026?
Yes. 69 € for the replacement versus 189 € for a used device in comparable condition. OnePlus still supplies the OnePlus 7 Pro with OxygenOS updates for 2 more years — the device stays secure and usable.
