iPhone 12 Pro Max Battery Replacement Singapore
Is your iPhone 12 Pro Max not lasting through the day? When battery health drops below 80%, replacement restores your iPhone to near-original battery performance. The 12 Pro Max’s 3,687mAh battery drives a 6.7-inch OLED display and 5G modem, so an aged cell can drain noticeably faster on mobile data.
About the iPhone 12 Pro Max Battery
Released in 2020, the iPhone 12 Pro Max has a 6.7-inch Super Retina XDR OLED display, the A14 Bionic chip, 5G and a 3,687mAh (14.13Wh) battery. It supports 20W wired fast charging over Lightning, 15W MagSafe and Qi wireless charging.
As the battery ages, iOS can enable performance management to avoid sudden shutdowns, which makes the phone feel slower. A new Grade A battery removes that throttling and restores full-day use. Because Apple pairs batteries to the logic board, an “Important Battery Message” may appear in Settings after replacement — the battery works normally.
Repair time: 30-45 minutes | Warranty: 90 days
Signs Your Battery Needs Replacing
| Battery health below 80% in Settings |
| Phone shuts down unexpectedly |
| Battery drains rapidly |
| Does not last through a full day |
If the display is lifting away from the frame, unplug the phone and stop charging it. Don’t squeeze the bulge or try to pry the phone open, keep it away from heat, and bring it to us as soon as possible.

Frequently Asked Questions
How long does battery replacement take?
Completed in approximately 30 to 45 minutes on the spot.
Will battery health show 100% after replacement?
The new battery restores full capacity. On iPhone XS and later, iOS may show an “Important Battery Message” or “Unknown Part” notice and may not display a Battery Health percentage for a non-Apple battery — the battery itself works normally.
