Battery Life: Charge Speed

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.
