how much battery
you have left.

Battery Life showing estimated runtimes for audio, video, streaming and standby.

Features

Everything about your battery, in one place.

No guesswork and no jargon — just the numbers your devices already know, laid out clearly.

Battery health

Your battery's real maximum capacity and charge cycle count, for your iPhone, iPad and Apple Watch, taken from the analytics files iOS already writes every day. With Pro, follow how your battery ages over time and keep the readings in sync across your devices with iCloud. How it works ›

Runtimes at a glance

See how long your device will keep going for the things you actually do — audio, video, streaming and standby — instead of a single percentage with no context.

Raw battery data

Current charge and battery capacity, read straight from the device. Tap any reading to dig into the detail behind it.

Paired devices

Apple Watch, AirPods and other connected accessories, each with its own charge level.

Custom notifications

Get told when charging passes the level you choose — and again when the battery runs low.

Widget

A widget that puts your device's runtimes one swipe away, without opening the app.

Apple Watch

Complications,
done right.

Battery Life ships a native watchOS app, so both charge levels are on your wrist the moment you raise it — no phone required.

Both batteries, one glance. Watch and iPhone charge levels side by side in the Watch app.
A complication for every face. A wide variety of styles so it fits the watch face you already use.
Kept in sync. Levels update between your devices, with a timestamp so you know how fresh a reading is.
