Apple Watch
Have you ever wondered how long your Apple Watch battery will last?
PowerGlass turns your battery percentage into a live time-remaining prediction, based on how you actually use your watch. By learning your real-world usage patterns, it shows you exactly how many hours you have left.
Your battery drain isn't constant, and neither is your lifestyle. PowerGlass continuously adapts as your habits change, keeping its predictions accurate as your routine evolves.
Key Features
• Personalised time-remaining predictions driven by your hourly usage patterns
• Dual-mode learning with separate models for Standard and Low Power Mode
• Multiple complications: circular gauge, rectangular with usage graph, corner, inline and compact
• Depletion time estimate - see the day and time you'll need to charge
• Achievements that reward consistent usage and learning milestones
• Customisable rectangular complication - choose which metrics to display
• 24-hour usage graph showing your drain pattern across the day
• Power-user tools: inspect data, track learning progress, and adjust learning speed
The more you use it, the smarter it gets - giving you confidence in every charge.
Note: In Low Power Mode, Apple Watch restricts background app refresh. To maintain learning accuracy, open the app periodically while in this mode.
