Detailed overview: SiGN iPhone 14 battery kit

This 3279 mAh replacement battery restores the iPhone 14's original capacity, the highest of the four generations we cover.

The kit is complete: the battery, the disassembly tools (screwdriver, spudger, pick) and the adhesive strips for reassembly. Nothing else to order, beyond a little patience and a clear workspace.

The iPhone 14 has a real advantage over its elders: Apple rebuilt its insides around a metal chassis with a removable glass back. The battery is reached from the rear, directly, where the 11, 12 and 13 require opening from the screen. iFixit called it the deepest redesign since the iPhone X and raised the model's repairability score to 7 out of 10. Careful: this applies only to the standard iPhone 14. The iPhone 14 Pro keeps the older architecture, and this kit is not meant for it.

The phone itself tells you when to act: Settings > Battery > Battery Health shows the remaining maximum capacity as a percentage. Below 80 %, runtime drops off sharply and iOS eventually displays a service message.

The same kit exists for the other generations: iPhone 11 battery kit, iPhone 12 battery kit and iPhone 13 battery kit. For a newer model, see our batteries for iPhone 15 battery and iPhone 16 battery.

Frequently asked questions: SiGN iPhone 14 battery kit

🔋 Is replacement easier on the iPhone 14 than on earlier models?

Markedly so. Apple redesigned the 14's interior around a metal chassis whose glass back comes off, giving direct access to the battery, held by pull-tab adhesives. On the 11, 12 and 13 you have to open from the screen. iFixit scored this redesign 7 out of 10 for repairability, unseen since the iPhone X.

🔋 Does this kit fit the iPhone 14 Pro?

No. The internal redesign applies only to the standard iPhone 14; the 14 Pro and 14 Pro Max keep the previous generations' architecture and a different battery. Check the exact model in Settings > General > About before ordering.

🔋 At what percentage should you replace an iPhone 14 battery?

Look at Settings > Battery > Battery Health: below 80 % maximum capacity, replacement is justified. Starting from 3279 mAh, the largest reserve of the four, the iPhone 14 absorbs the first lost percentages better.

🔋 How much does an iPhone 14 battery replacement cost?

This kit is £26.50, tools and adhesives included. It is the dearest of the four generations, in line with capacity, but also the one that takes the least effort to fit thanks to the removable back.
