iPhone 11 Pro Max Battery Replacement Singapore
Is your iPhone 11 Pro Max not lasting through the day? When battery health drops below 80%, replacement restores your iPhone to near-original battery performance. The 11 Pro Max launched with the biggest battery Apple had fitted to an iPhone at the time, but after several years of charge cycles most units are well below their original capacity.
About the iPhone 11 Pro Max Battery
The iPhone 11 Pro Max (models A2161, A2218 and A2220) was released in 2019 with a 6.5-inch Super Retina XDR OLED display, the A13 Bionic chip and a 3,969mAh (15.04Wh) battery that supports 18W fast charging and Qi wireless charging.
You can check wear in Settings › Battery › Battery Health. Once maximum capacity falls below 80%, iOS may throttle performance to prevent shutdowns. After a non-Apple battery is fitted, an “Important Battery Message” notice can appear in Settings; the phone keeps working normally.
Repair time: 30-45 minutes | Warranty: 90 days
Signs Your Battery Needs Replacing
| Battery health below 80% in Settings |
| Phone shuts down unexpectedly at 20-30% charge |
| Battery drains rapidly |
| Does not last through a full day on one charge |
If the display of your 11 Pro Max starts separating from the frame, the battery underneath may be swelling. Stop charging, don’t squeeze the screen back down or open the phone yourself, keep it away from heat and bring it in quickly.

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.
