Battery vs new phone: the real cost comparison

iPhone 14 is a current, fully-supported phone. A £17.99–£22.99 battery replacement restores genuine all-day performance for a fraction of what any replacement device costs — by far the best value fix available if battery life is your only complaint.

Fitting overview

Standard process across the range: power down, remove the two pentalobe screws by the charging port, lift the display on its hinge, disconnect the battery connector first, then carefully release the adhesive pull-tabs before lifting the old battery out. Fit the new cell, reconnect, test, then reassemble. Not confident doing it yourself? A local repairer will fit it same-day.

FAQ

Which iPhone 14 battery do I need?

Check Settings > General > About for your exact model — standard, Plus, Pro, and Pro Max batteries are all different parts.

Why is the Pro model's battery more expensive despite lower capacity?

Pro models use a more complex internal layout around the camera and sensor housing, which affects part cost independent of raw mAh capacity.

Is a third-party battery as good as Apple's original?

A genuine-quality replacement restores capacity and performance close to original specification. iOS may show a "genuine part" notice under Battery Health, which is informational only.

How long will the repair take?

A confident DIY fit is typically 20–30 minutes; a professional repairer usually completes it within the hour.
