iPhone 16 Plus Repair – Swollen Battery Causing Constant Restarts

At BlitzinGroup UK Electronic Repairs, we recently had an iPhone 16 Plus brought into the workshop after the customer reported it was constantly restarting and becoming unreliable to use.

After opening the device for diagnostics, the issue became clear straight away — a swollen battery, often nicknamed a “spicy pillow” due to the dangerous pressure build-up inside the battery cell.

A swollen battery isn’t just a performance issue — it can become a serious safety hazard if left untreated. It can cause overheating, damage internal components, push the screen away from the frame, and in extreme cases even catch fire.

The Repair Process

Our technician safely removed the damaged battery and fitted a brand-new replacement, carrying out full testing afterwards to make sure everything was running correctly.

✅ Swollen battery safely removed

✅ New battery professionally install

✅ Device fully tested

✅ Restarting issue resolved

✅ Back to full working order

The phone is now working perfectly again with no more random rebooting.
