Apple Watch Battery Prices

If your Apple Watch is not holding charge, shutting off too quickly, or struggling to power on, the battery is likely the issue. Like all lithium-ion cells, Apple Watch batteries degrade over time. Whether it is from daily charging cycles, extended periods on charge, or natural ageing, battery failure is the most common issue we see across all Apple Watch models.


At iCorrect, we replace Apple Watch batteries using original Apple batteries pulled from donor devices and tested in-house. Each battery undergoes thorough diagnostics before and after installation to ensure it meets Apple’s performance standards. We ask for 2 to 3 working days to complete the repair because curing and sealing the watch to maintain its water resistance takes time.

Our Process

A worn Apple Watch battery does more than shorten screen-on time. It can lead to slow wake-up response, connection drops, overheating, and in some cases, swelling that pushes against the screen or case. Replacing a failing battery early can prevent bigger issues, including permanent damage to the screen or back housing.


Our replacement process includes full diagnostics, a battery rundown and charging profile test, resealing to restore water resistance, and a final quality control check. We only use batteries that have passed our in-house testing and are approved for reliability and cycle health.


Whether you rely on your Apple Watch for work, fitness, or daily life, a healthy battery makes a big difference. This is one of the most valuable repairs you can complete to extend the life of your Apple Watch.

FAQs

Learn more about iCorrect, the essential repair services that we offer and the warranties that come with each repair.

How do I know if my Apple Watch battery needs to be replaced?

 If your Apple Watch runs out of charge quickly, shuts off unexpectedly, becomes slow to respond, or does not last a full day anymore, it is likely the battery. In some cases, a swelling battery can lift the screen or cause the case to separate. We run a full diagnostic to confirm the issue before any repair.

How much does an Apple Watch battery replacement cost?

Battery replacements start from £159, depending on your model. The price includes diagnostics, installation of an original battery, water resistance resealing, and full performance testing.

Do you use original Apple Watch batteries?

Yes. We use original Apple batteries reclaimed from donor devices. Each one is tested for charge capacity, thermal output, and overall cycle health. We do not use aftermarket or third-party batteries.

 How long does the battery replacement take?

We ask for 2 to 3 working days. This allows time for full testing, adhesive curing, and resealing to maintain water resistance. If your battery is swollen or the screen is lifting, additional time may be needed.

Is the Apple Watch still water resistant after a battery replacement?

Yes. We reseal every Apple Watch using high-strength adhesives that match Apple’s factory bonding process. The device is safe for showers and general water exposure, though, like Apple, we do not warranty against water damage.

Will my Apple Watch performance improve with a new battery?

Yes. A fresh battery restores energy flow and helps maintain the watch’s performance, responsiveness, and Bluetooth/Wi-Fi stability. Many clients notice faster load times, better wake response, and more consistent connection to their iPhone.

Do you test the battery before and after the repair?

Absolutely. We run a rundown test before we proceed, and post-repair, we check charge behaviour, thermal profile, and battery reporting to confirm everything is working perfectly.

What kind of warranty do you offer on Apple Watch battery repairs?

We offer a two-year warranty covering faults with the battery or our workmanship. Accidental damage or battery degradation over time is not covered, but if anything fails due to the repair itself, we will put it right.

Can a bad Apple Watch battery damage the screen?

Yes. A swollen battery can put pressure on the screen, causing lifting, cracking, or permanent screen separation. This is one of the reasons we recommend replacing a faulty battery early.

Can I walk in for same-day Apple Watch battery replacement?

No. Because of the testing, curing, and sealing required, we do not offer same-day service. We prioritise doing the repair properly, not rushing it. The process typically takes 2 to 3 working days.
