iPhone 12 battery: 2815 mAh. iPhone 12 mini: 2227 mAh. Here are 20 models, with prices.

Apple doesn’t publish battery capacity in mAh, but teardowns and replacement cells do. This is the capacity for 20 iPhone models from the XR to the 15 Pro Max, what it costs to replace in India, what the number means next to battery health, and how to choose the right battery. Plus, SE and other models are not covered here; message us with yours.

Battery capacity by iPhone model

Tap a model to open its battery listing. Capacities are the figures printed in our listings; for the iPhone 13 we give the teardown figure because the listing does not state one.

How the batteries compare at a glance

The chart shows the same capacities as bars, so you can see how the mini models fall behind and where the Pro Max models sit.

Why one iPhone shows two different mAh figures

You may see 2406 mAh for the iPhone 13 mini on one site and 2438 mAh on another. Apple publishes neither. Teardowns read the number printed on the battery, and replacement makers print their own rated figure. Expect differences of a percent or two between sources. Use the figure for your exact model as a guide to size, not as a promise of runtime.

mAh or battery health: what to look at

mAh tells you the size of the battery when it was new. Battery health tells you how much of that is left. On your iPhone, open Settings › Battery › Battery Health to see maximum capacity as a percentage. A bigger mAh doesn’t mean a healthier battery, and a smaller one doesn’t mean a worse phone. The mini models simply have less room inside.

If your health is low and your phone is draining fast, read our guide on iPhone slow or draining after iOS 27 before you replace anything.

Before you order a battery: 4 checks

1. Match the exact model, including mini, Plus, Pro and Pro Max. Batteries are not interchangeable between them.
2. Check battery health.Replace when it is clearly low or the phone shuts down, not just because the percentage fell by a few points.
3. Be careful with big claims.The space inside the phone is fixed. Treat a battery that claims far more mAh than the figure here with caution.
4. Ask about fitting.Message us with your model and city and we’ll explain how fitting works for you.
