Typical battery problems with the OnePlus 15
- Your OnePlus 15 no longer lasts a full working day — 6 to 8 hours of screen time used to be no problem
- The device shuts down on its own between 20 and 30 % remaining charge, especially in cold weather
- The 7300 mAh battery gets noticeably hot during SUPERVOOC 120W charging, and charging is throttled
- The battery percentage indicator jumps in large steps instead of falling steadily
- The back panel bulges visibly around the battery area — a clear sign of swelling
- The OnePlus 15 no longer turns on after a full discharge, not even on the charger
- OxygenOS reports clearly reduced capacity in the battery settings
How does the OnePlus 15 battery replacement work?
- Battery diagnosis
OxygenOS battery display plus our voltage measurement on the battery module. At under 80 % capacity or more than 500 full cycles, we recommend a replacement.
- Opening the display carefully
The OnePlus 15 is opened with a special suction cup, flex cables are released, the panel is fixed on the stand.
- Loosening the battery adhesive strips
The 7300 mAh cell is fixed to the frame with pull tabs. We loosen it with 99 % isopropanol, never with a screwdriver as a lever.
- Inserting 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-bonding the display and calibration
New gasket on the frame, panel bonded under pressure, 30 minutes curing time. Then a full charge for calibration.
- Testing and fast-charge check
OxygenOS battery health, voltage curves, charging speed with the original OnePlus SUPERVOOC 120W power adapter.

What does the battery replacement cost for the OnePlus 15?
99 € fixed price. This includes the cell, installation, calibration, bonding technique and 6 months warranty. No hidden surcharges.
How long does the new OnePlus 15 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 SUPERVOOC 120W work on the OnePlus 15 after the battery replacement?
Yes. On the OnePlus 15 the fast-charge logic sits on the mainboard and the charging chip, not in the cell. Our replacement cell supports the full SUPERVOOC 120W protocol — charging in the same time as before.
Does OxygenOS stay unchanged on the OnePlus 15 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 all remain fully intact.
How long does the OnePlus 15 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 15 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, send the device to us; hazardous-goods disposal of the old cell is included.
Can I drop off my OnePlus 15 in Vienna for the battery replacement?
No, Reparo has no customer drop-in. Battery repairs run via online booking plus courier pickup in all 23 Vienna districts. From the provinces, insured shipping in a hazardous-goods box.
Battery replacement via pickup service — how does it work for the OnePlus 15 in Vienna?
You choose a preferred time window online (9 am to 6 pm), the courier collects the device, we replace the cell in 60–90 minutes, return the same day. The courier is included in the battery fixed price.
Shipping from the provinces: is the OnePlus 15 battery replacement safely possible?
Yes. Shipping both ways is done in a UN-approved hazardous-goods box with transport insurance — regularly devices from Graz, Linz, Salzburg, Klagenfurt, Innsbruck and Bregenz.
Is data lost during the OnePlus 15 battery replacement?
No. The flash storage, OnePlus account, SIM and all apps remain untouched. We still recommend a backup — it makes things more relaxed.
How long is the warranty on the new OnePlus 15 battery?
Six months of Reparo warranty on the cell and installation. If a defect occurs within that time: free re-replacement, without a second diagnostic fee.
Do I lose the OnePlus warranty on the OnePlus 15 through the battery replacement?
The OnePlus 15 factory warranty (2 years) expired a year ago — so nothing is lost there. What you get: 6 months of Reparo warranty from installation.
My OnePlus 15 charges slower than before — battery or power adapter?
Often both together. An aging battery throttles the charging current for self-protection, while at the same time the USB port may be corroded. Our diagnosis (25 €, waived on repair) separates that cleanly.
Is the OnePlus 15 battery replacement still worth it in 2026?
Yes. 99 € for the replacement versus 749 € for a used device in comparable condition. OnePlus still supplies the OnePlus 15 with OxygenOS updates for another 4 years — the device stays secure and usable.
