Signs your iPhone 12 battery needs replacing

• Battery Health under 80% in Settings > Battery > Battery Health & Charging.
• Random shutdowns, especially in cold weather or below 30% charge.
• Noticeably shorter screen-on time than when the phone was new.
• Peak performance capability messages — iOS will actually tell you if it has throttled performance to protect an aging battery.
• Swelling around the screen or back glass — stop use and replace immediately; this is a safety issue.

Why a battery swap beats buying a new phone

The iPhone 12 range still runs current iOS comfortably. If battery life is the only complaint, a £14.99–£17.99 replacement restores realistic all-day use for a fraction of the price of any new or refurbished phone — the most cost-effective upgrade available for this generation.

Fitting: DIY or professional

iPhone 12 battery replacement follows the same broad process as other recent iPhones: disconnect the battery before touching any other connector, release the adhesive pull-tabs slowly and evenly, and avoid puncturing the cell with a metal tool. If you'd rather not do it yourself, a local independent repairer will fit it same-day, usually with a workmanship warranty on top.

FAQ

How long does an iPhone 12 battery replacement take?

A confident DIY fit typically takes 20–30 minutes. Professional repairers often complete it within the hour.

Is the iPhone 12 / 12 Pro battery back in stock?

Check the product page for live availability, or contact us — we restock regularly and can confirm the next delivery.

Will a new battery fix random shutdowns?

In almost every case, yes — sudden shutdowns are one of the clearest signs of a degraded battery unable to supply peak current.

Do I need any special tools?

A standard phone opening kit (pentalobe and Phillips screwdrivers, spudgers, suction handle) covers it. No soldering required.
