## What is Battery Life?

Plug in your charger and see how fast your phone is really charging.

Battery Life is a screen made to stay on while you charge. A big flip clock, the weather, calm music and beautiful photos sit around a clear view of your charging speed and the time left.

CHARGING SPEED IN NUMBERS
- See your current charging speed in watts (W), shown large.
- Four simple grades: slow, standard, fast and super fast. Know right away how good your charger and cable are.
- Swap chargers and compare which one is faster.

TIME TO FULL
- Get an estimate of the time left until 100%.
- Phones slow down on purpose after 80% to keep the battery healthy. The estimate includes that slower stretch.

PAST 80%, EXPLAINED KINDLY
- When the number drops after 80%, it can look like something is wrong. We explain why in plain words, and show where to find your charger's real speed.
- The early speed of this charge is remembered and shown alongside.

THIS CHARGE AT A GLANCE
- Start time, how much has been added, how fast it rises per minute and a charge graph, all on the details screen.
- A USB-C animation shows energy flowing up into your phone.

A SCREEN WORTH LEAVING ON
- Flip clock, current weather, music and photos that match the time of day.
- Wake-up alarm and sleep mode included.

QUIET ALL NIGHT
- The screen stays on while you charge. After 3 minutes untouched, rest mode stops all motion. At night (midnight to 7 am), or when you seem to be asleep, the screen slowly dims so it never wastes battery while you sleep. Tap to wake it.

GOOD TO KNOW
- iPhone does not tell apps the charging wattage. On iPhone, watts are an estimate calculated from how fast the battery level rises and the battery capacity of your model.
- This app shows battery information only. It does not change your battery or charging speed.
- Available in 14 languages, including English, Korean, Japanese, Chinese, Spanish, Portuguese, German, French, Italian, Russian, Indonesian, Vietnamese, Thai and Turkish.
