Signs your iPhone 15 battery needs replacing

• Battery Health below 80% — Settings > Battery > Battery Health & Charging.
• Unexpected shutdowns well above 0% charge.
• Fast drain during light use — browsing or messaging draining the battery noticeably faster than a few months ago.
• USB-C charging feels slower or less reliable than when the phone was new.
• Visible swelling — stop using the phone immediately and replace the battery.

Why replace instead of upgrade

iPhone 15 is a fully current phone with years of software support ahead. A £16.59 battery is a tiny fraction of any upgrade cost, and it's the single most effective fix for "my phone doesn't last as long as it used to."

Fitting overview

Power down, remove the pentalobe screws by the charging port, lift the display carefully on its hinge, disconnect the battery connector first, then release the adhesive pull-tabs slowly and evenly. Fit the new battery, reconnect, test, then reassemble. If you'd rather not do it yourself, a local repairer can fit it same-day.

FAQ

Which iPhone 15 battery do I need?

Check Settings > General > About — iPhone 15 and iPhone 15 Plus use different-capacity batteries and are not interchangeable.

Why isn't there a Pro or Pro Max battery listed?

We're still sourcing that specific part. Contact us and we'll confirm availability and timing for your model.

Will a new battery restore full performance?

Yes — a genuine-quality replacement resolves the shutdowns and fast drain caused by a degraded original cell.

Is it a safe DIY repair?

Yes, with a proper opening kit and careful handling of the adhesive strips and battery cell. If unsure, book a professional fitting instead.
