How does the iPhone 8 Plus battery replacement work?
- Battery diagnosis via iOS + measuring device
iOS display (Settings → Battery → Battery Health) + our voltage/impedance measurement at the battery module. At < 80 % capacity or cycle count > 500 we recommend a replacement.
- Open the display carefully
The iPhone 8 Plus is opened with a special suction cup and heated adhesive edge. The display flex cables are disconnected, the panel held on a stand – no pulling.
- Release the battery pull tabs
From iPhone X on, the battery sits in 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 high-quality replacement cell to Apple specification with 2691 mAh is fitted precisely. New Apple adhesive strips, connector on the mainboard with correct contact pressure.
- Reseal the display + iOS calibration
New seal on the frame, display panel bonded under pressure, 30 min curing time. Then a full charge to 100 % – iOS recalibrates the battery gauge to the new cell.
- Test + health check
We check battery health in iOS, voltage curves, charging speed. Only after a full test do you get your iPhone 8 Plus back.
Replacing the iPhone 8 Plus battery – price, process and lifespan in Vienna

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

From which battery health percentage is an iPhone 8 Plus battery replacement worthwhile?
Apple itself recommends a replacement from below 80 % maximum capacity (iOS → Settings → Battery → Battery Health). In practice, battery weakness on the iPhone 8 Plus usually becomes noticeable from 85 % – sudden shutdowns or runtime cut in half. At 75 % a replacement is definitely worthwhile.
Does iOS show "Important Battery Message" after the iPhone 8 Plus battery replacement?
Yes, probably. Since iPhone 11 Apple pairs the battery with a service chip – if the battery is replaced, iOS warns "Unable to verify this iPhone has a genuine Apple battery". This is not a defect, your iPhone works fully – the battery lasts just as long. The message disappears by itself after a few days.
Does lightning charging still work on the iPhone 8 Plus after the battery replacement?
Yes. The lightning port sits on the mainboard and is not touched during the battery replacement. Our replacement cell supports the USB-PD protocol up to 18W – the same charging speed as from the factory.
Does the iPhone 8 Plus have MagSafe?
No. MagSafe has only existed since iPhone 12 (2020). Older iPhones like yours have Qi wireless charging at 7.5W. That changes nothing for the battery replacement – we replace the battery as usual for 55 €.
