Description
Apple Watch battery percentage tells you how much charge you have — not how long it will last. PowerGlass fixes that.
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 — whether that’s 4 hours or 40.
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
• Adaptive behaviour that evolves as your daily routines shift
• Multiple widgets: circular gauge, rectangular, and compact corner glance
• Power-user tools: inspect data, track learning progress, and export datasets
The more you wear 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.
