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.

Match the battery to your exact model and, where listed, the board revision — capacity and connector shape vary between variants. Many iPhone batteries need a Battery Health Interface transfer to clear the "Service" warning and keep the health percentage; listings note when this applies. Never install a swollen battery — replace it. Not sure which part fits, or want it installed? Our New Haven, CT shop can identify the exact part and handle the repair — book a repair and we'll take care of it.

Frequently asked questions

Why does my phone say 'Service' after a battery swap?
On newer iPhones the battery reports health through a small chip. If it isn't transferred or re-paired, iOS shows a Service message even with a new battery. Our shop can pair it during installation.
How long should a replacement battery last?
A quality replacement restores near-original runtime and typically lasts 1.5–2+ years depending on charging habits and heat. All of ours ship fresh, not old stock.
Is it safe to replace a swollen battery myself?
A swollen battery should be handled carefully and replaced promptly, never punctured. If you're unsure, book a repair and we'll remove and recycle it safely.
Do batteries come with a warranty?
Yes — every battery includes our 90-day warranty and ships same-day from our Manassas, VA warehouse.
