iPhone 11 Battery Replacement Singapore
Is your iPhone 11 not lasting through the day? Lithium-ion batteries degrade with each charge cycle, typically losing around 20% capacity within 400-500 cycles. When battery health drops below 80%, replacement restores your iPhone to near-original battery performance. The iPhone 11’s 3,110mAh battery has to power a 6.1-inch LCD and the A13 Bionic chip, so a worn cell soon shows up as unexpected shutdowns.
About the iPhone 11 Battery
Apple released the iPhone 11 in 2019 with a 6.1-inch Liquid Retina HD LCD, the A13 Bionic chip and a 3,110mAh (11.91Wh) battery. It supports 18W fast charging over Lightning with a USB-C Power Delivery adapter, as well as Qi wireless charging.
When the battery wears out, iOS may turn on performance management to stop sudden shutdowns, making the phone feel slow. A new Grade A battery lifts that limit and restores full-day use. Because Apple pairs batteries to the logic board, Settings may show an “Important Battery Message” after the swap — the battery itself 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 at 20-30% charge |
| Battery drains rapidly from 30% to 0% |
| Phone feels warm during normal use or charging |
| Does not last through a full day on one charge |
If the screen starts lifting or the phone won’t sit flat, stop charging it right away. Don’t press on the swelling or try to open the phone yourself; keep it somewhere cool and bring it in promptly.

Frequently Asked Questions
How do I know if my iPhone 11 battery needs replacement?
Check Settings > Battery > Battery Health. If below 80%, replacement is recommended. Signs include unexpected shutdowns, rapid drain, and overheating.
How long does battery replacement take?
Completed in approximately 30 to 45 minutes on the spot.
Will battery replacement affect my Apple warranty?
Third-party repairs may affect Apple warranty. Certified Phone Repair SG provides its own 90-day warranty.
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.
