About
BigBattery turns your iPhone into a big, clear charge display you can read from across the room.
• Huge battery indicator — the battery fills the screen and gets even bigger when you turn the phone sideways.
• Widgets — circular, rectangular and inline widgets for the Lock Screen, plus small and medium Home Screen widgets. They update on their own and also appear in StandBy while charging.
• Big clock — a large clock above the battery makes it a perfect nightstand display while your phone charges.
• Charge alert — choose a level from 50 to 100% and one of five melodies to know when your phone is charged.
• Charging animation — see at a glance that charging is in progress.
• Keep the screen on while charging — the screen stays awake on the charger and locks as usual when you unplug.
• Charging mode — turn on iOS Low Power Mode with a shortcut while your phone charges.
• Color styles — by charge level, monochrome or accent.
Precise to the percent: iOS reports the battery level to apps in 5% steps, so BigBattery estimates the exact percentage between steps from your charging speed.
