iPhone 16 Battery Replacement Singapore
The iPhone 16 comes with a 3,561 mAh battery that Apple rates for up to 27 hours of video playback. Over time, lithium-ion batteries degrade with each charge cycle — typically losing around 20% capacity within 400 to 500 charge cycles under normal use. When your battery health drops below 80%, Apple itself recommends a replacement.
At Certified Phone Repair SG, we replace your iPhone 16 battery with a Grade A equivalent battery that restores your phone to near-original battery life. The replacement is completed in 30 to 45 minutes on the spot.

Frequently Asked Questions
How do I know if my iPhone 16 needs a battery replacement?
Check your battery health in Settings > Battery > Battery Health. If it is below 80%, replacement is recommended. Other signs include the phone shutting down unexpectedly, charging very slowly, overheating during normal use, or the battery percentage dropping rapidly.
How much does iPhone 16 battery replacement cost in Singapore?
iPhone 16 battery replacement at Certified Phone Repair SG costs $88, fully inclusive of parts and labour.
How long does battery replacement take?
iPhone 16 battery replacement is completed in approximately 30 to 45 minutes on the spot.
Will battery replacement affect my iPhone 16 warranty?
Apple’s warranty only covers original Apple repairs. Third-party repairs may void the Apple warranty. However, Certified Phone Repair SG provides its own 60-day warranty on the replacement battery.
Should I turn off Optimised Battery Charging after replacement?
After a battery replacement, it is a good idea to recalibrate the battery. Charge it fully to 100%, use it until it drains, then charge to 100% again. Optimised Battery Charging can remain on as it helps extend the new battery’s long-term health.
Will my iPhone 16 show battery health as 100% after replacement?
With a Grade A battery replacement, your battery health should reset to 100% or show as maximum capacity. For iPhone 12 and newer, a service notification may appear in Settings due to Apple’s parts pairing — this is cosmetic only and does not affect battery performance.
