Batteries

Buying guide How to pick the right batterie

OEM vs aftermarket battery — does it matter? Yes. Genuine OEM (or Service Genuine) batteries are the only ones guaranteed to show full Battery Health %, support paired-battery service on iPhone XR and newer, and trigger no "Important Battery Message" warning. Aftermarket batteries (typically $50–$80 less) work fine but may show "Unknown Part" in Settings → Battery Health and drop the % indicator entirely.

What is "battery pairing" and do I need it? Apple introduced battery pairing on iPhone XR (2018). The phone authenticates the battery's serial number against Apple's servers. Unpaired batteries (most aftermarket) work but display the warning above. We can perform paired-battery service for OEM swaps in-shop ($20 add-on).

Lifespan expectations: a quality replacement battery typically retains 80%+ capacity for 500 charge cycles (~18–24 months of daily use). Bring the phone in for a free battery health check if your current one drops below 80% — Apple replaces under 80% under their service pricing too.
