Is it worth replacing an iPhone battery?

Check before you spend anything

Go to Settings → Battery → Battery Health & Charging and look at Maximum Capacity. That percentage is how much charge the battery can still hold compared to when it was new.

• 90% or above — the battery is fine. If the phone is still dying quickly, something else is going on.
• 80% to 90% — you will notice it, and a replacement will help.
• Below 80%, or a "Service" message — it is worn out. Replace it.

The other signs

Battery Health is not the whole story. These all point at a worn battery too:

• The phone shuts down suddenly with charge still showing — 30%, sometimes more.
• It gets warm doing very little.
• It drops in big jumps — 60% to 20% in one go.
• It dies quickly in the cold. Worn batteries hate winter.
• The screen or back is lifting — that is a swollen battery, and it needs doing now rather than later.

Is it worth it against a new phone?

Almost always, yes. A battery replacement on most iPhones costs between £50 and £85. A new phone costs several hundred. If everything else about your phone is fine — the screen is good, it does what you need, you are not desperate for a new camera — a battery is by far the better spend.

The exception is a phone that has other things wrong with it too. If the screen is cracked and the charging port is going, we will tell you honestly whether it is worth putting money into.

What we fit

On the iPhone 12 and newer we fit genuine Apple batteries, taken from real Apple handsets, and only the best grade available for each model. On older phones Apple parts are no longer produced, so we fit the highest aftermarket tier instead.

On most models we come in under Apple's own out-of-warranty service price, and you are not posting your phone away or waiting on an appointment.

Every model and price is listed on our iPhone battery replacement page.
