Why iPhone 16 batteries cost more than older models

As this generation's newest range, iPhone 16 batteries currently carry a higher price than iPhone 11–15 equivalents — this reflects both the newer cell technology and the early-generation aftermarket pricing pattern we see with every new iPhone launch, which typically comes down over the following year as the supply chain matures.

Fitting overview

iPhone 16 introduced electrically-released battery adhesive across the range, generally safer once you know the process. Power down, remove the pentalobe screws by the charging port, lift the display, disconnect the battery connector, then release the adhesive using the correct method for this generation before lifting the old cell out. If you're unsure, a local repairer can fit it same-day.

FAQ

Which iPhone 16 battery do I need?

Check Settings > General > About — standard, Plus, Pro, and Pro Max all use different batteries.

Will iPhone 16 battery prices come down?

Based on the pattern with every previous generation, aftermarket pricing typically eases as the parts supply chain matures over the following year.

Does the new adhesive design make DIY harder?

It's different from older iPhones — electrically-released rather than pull-tab — but not harder once you know the correct process. If in doubt, book a professional fitting.

Will a new battery fix Camera Control or Action Button drain?

If the drain is disproportionate to normal use, a degraded battery is a likely cause, and a replacement typically resolves it.
