How does the iPhone 15 Plus battery replacement work?
- Battery diagnosis via iOS + measuring device
iOS reading (Settings → Battery → Battery Health) + our voltage/impedance measurement at the battery module. At < 80 % capacity or cycle count > 500 we recommend a replacement.
- Carefully open the display
The iPhone 15 Plus is opened with a special suction cup and a heated adhesive edge. The display flex cables are disconnected, the panel is held on a stand – no peeling off.
- Loosen the battery pull tabs
Since the iPhone X the battery is fixed to the frame with three pull tabs. We pull them out in parallel – with torn tabs: drip isopropanol 99 under the battery, loosen the adhesive strips without bending.
- Insert the new battery
A certified li-polymer cell (Apple-compatible) with 4383 mAh is fitted precisely. Fresh Apple adhesive strips, connector on the mainboard with correct contact pressure.
- Re-seal the display + iOS calibration
New seal on the frame, display panel glued under pressure, 30 min curing time. Then a full charge to 100 % – iOS re-calibrates the battery gauge to the new cell.
- Test + health check
We check battery health in iOS, voltage curves, charging speed, MagSafe function. Only after a full test do you get your iPhone 15 Plus back.

After 500 to 800 full cycles the maximum capacity typically drops to 80 % – reached after 2-3 years of daily use. iOS shows exactly where you stand under Settings → Battery → Battery Health.

Certified battery cell vs. original – what goes into the iPhone?
Apple battery replacement cells are not available to third parties. Our certified cells meet Apple's original specifications: same nominal voltage (3.85 V), same capacity, same charging curve.

At what Battery Health percentage is the iPhone 15 Plus battery replacement worth it?
Apple itself recommends a replacement below 80 % maximum capacity (iOS → Settings → Battery → Battery Health). In practice, battery weakness on the iPhone 15 Plus usually becomes noticeable from 85 % – sudden shutdowns or a halved runtime. At 75 % the replacement is definitely worthwhile.
Does iOS show "Important Battery Message" after the iPhone 15 Plus battery replacement?
Yes, most likely. Since the iPhone 11, Apple pairs the battery with a service chip – if the battery is replaced, iOS warns with "Unable to verify this iPhone has a genuine Apple battery". That is not a defect, your iPhone works fully – the battery lasts just as long. The message disappears by itself after a few days.
Does USB-C charging still work on the iPhone 15 Plus after the battery replacement?
Yes. The USB-C port on the iPhone 15 Plus sits on the mainboard, not on the battery. Our replacement cell supports the full 20W Power Delivery protocol. Charging with original USB-C PD power adapters in the same time as before.
Does MagSafe charging stay intact on the iPhone 15 Plus after the battery replacement?
Yes. The MagSafe coil on the iPhone 15 Plus sits under the back glass on a separate assembly, not on the battery. For a battery replacement we open from the front (display) – the MagSafe coil and the magnet rings remain completely untouched. 15W wireless after the replacement just like before.
How long does the iPhone 15 Plus battery replacement take?
The iPhone 15 Plus battery replacement usually takes 60–90 minutes of actual work at Reparo. With pickup service in Vienna you often get the device back the same working day.
My iPhone 15 Plus is bulging at the back – is that dangerous?
Yes, potentially. A swollen battery has built up gas pressure (cell chemistry at its end) – risk of fire/explosion, especially in heat. Come to us right away: hazardous-goods disposal directly by Reparo, replacement for 79 €.
Can I drop off my iPhone 15 Plus directly at Reparo?
Reparo has no on-site customer access. You book an appointment online – our courier comes to your address in all 23 Vienna districts. From the provinces, insured shipping, return shipping included in the price.
iPhone 15 Plus battery swap — what makes the larger 4,383 mAh cell last longer?
The iPhone 15 Plus battery swap costs 79 € fixed price. The 4,383 mAh cell is significantly larger than in the regular iPhone 15 (3,349 mAh) — hence the best runtime of the non-Pro models: 26 hours of video playback. Because of the larger display, however, the 15 Plus also consumes more — the net advantage in everyday use is about 30-40 % more runtime. iPhone 15 Plus battery swap with warranty: 6 months on installation, 12 months on the cell. Service chip pairing keeps the battery health display.
Is shipping from the provinces safe for an iPhone 15 Plus battery?
Yes. Battery shipping is subject to hazardous-goods class 9 – after booking we send a UN-approved shipping box. The iPhone 15 Plus arrives insured in Vienna and goes back the same way after the replacement. Regularly customers from Graz, Linz, St. Pölten, Klagenfurt, Innsbruck and Bregenz.
Is any data lost during the iPhone 15 Plus battery replacement?
No. The flash storage, iCloud account and SIM card are not disconnected during the battery replacement. Photos, iMessage, apps, settings – everything is fully retained. We still recommend an iCloud backup before any repair.
How long is the warranty on the new iPhone 15 Plus battery?
Six months on the battery cell and installation. If the cell loses more than 10 % capacity within that time: free re-replacement.
Do I lose the Apple warranty through the iPhone 15 Plus battery replacement?
The Apple original warranty (1 year) on the iPhone 15 Plus has long expired. Reparo warranty 6 months on the cell and labour.
Is the iPhone 15 Plus battery replacement still worth it in 2026?
Yes. The iPhone 15 Plus will be supplied with iOS updates by Apple for at least 5 more years. Battery replacement 79 € vs. a used device from around 450 € – plus data migration and a fresh setup.
