iPhone Battery Replacement Cost UK 2026: Complete Price Guide

Your iPhone battery is dying. You've checked Settings — it's showing 74% health and the phone barely makes it to lunch. Now you're wondering: how much does battery replacement actually cost in the UK?

Here's the quick answer: £59 to £169 depending on your iPhone model. That's with quality parts, a 27-month warranty, and your data completely untouched. Compare that to £699+ for a new iPhone, and the maths is pretty clear.

Apple vs Independent Repair: Price Comparison

You might be wondering why you'd choose us over Apple. Here's the honest comparison:

*iPhone 12 and later may show "Unknown Part" message after third-party battery replacement. This doesn't affect battery function or health tracking accuracy.

Did You Know?

When to choose Apple: If your iPhone is under AppleCare+ and battery health is below 80%, Apple replaces it free. Check your coverage at checkcoverage.apple.com

What's Included in the Price

When you get your battery replaced at celltech, here's exactly what you get:

• OEM-grade battery — Same capacity and chemistry as the original
• Professional installation — By technicians with 10+ years experience
• Water seal restoration — We replace the adhesive gasket on water-resistant models
• Full diagnostic check — We test charging, display, speakers, and cameras
• 27-month warranty — If anything goes wrong, we fix it free
• Data preservation — Your photos, apps, and settings stay exactly where they are

What We Don't Do

To be transparent, here's what's different from Apple:

• iPhone 12 and later will show "Unknown Part" in Settings (doesn't affect function)
• We use OEM-grade batteries, not genuine Apple batteries (same performance, different branding)
• We can't repair devices that require Apple account verification

How Long Does Battery Replacement Take?

Most iPhone battery replacements take 20-30 minutes while you wait. Here's the breakdown by model:

Newer models take longer because Apple has made the internal design more complex. The iPhone 14 onwards has a removable back glass (good for screen repairs) but more intricate battery mounting.

Is Battery Replacement Worth It for Your Model?

Here's our honest assessment of when battery replacement makes sense:

Definitely Replace

• iPhone 11-14 series — These are 2-4 years old, plenty of life left
• Battery health below 80% — You'll notice immediate improvement
• Phone otherwise works perfectly — No other major issues
• You don't need the latest features — 11/12/13 still handle everything most people need

Consider Carefully

• iPhone X or XS — Still capable, but 5-6 years old. Worth it if you're happy with the phone
• Battery health 80-85% — You might get another year without replacing
• Planning to upgrade within 6 months — Might be better to trade in now

Probably Don't Replace

• iPhone 8 or older — No longer getting iOS updates. Consider upgrade
• Multiple issues — Cracked screen + bad battery + charging problems = upgrade time
• Repair cost exceeds 50% of phone value — Better investment elsewhere

Pro Tip

Trade-in tip: If you're on the fence, check your trade-in value first. An iPhone 12 with a dying battery might get you £150. Replace the battery for £89, and that same phone could fetch £280-320. The maths often works in favour of repair-then-sell.
