🔋 Wear Battery Guardian High-resolution battery analytics, real-time drain tracking & performance scoring — all on your wrist.
Stop guessing how long your watch will last. Wear Battery Guardian is a powerful, watch-only battery intelligence suite that provides deep analytics into how your smartwatch drains, charges, and performs.
No phone required. No background data syncing. Just pure on-device intelligence.
🧠Smart Battery Intelligence Guardian doesn’t just show a percentage—it understands your usage patterns.
• Real-time Drain Rate: See exactly how many % you are losing per hour.
• Smart Trend Detection: Know instantly if your drain is increasing (↑) or improving (↓).
• Usage Mode Detection: Identifies Idle, Active, Heavy, or Unstable power behavior.
• Adaptive Predictions: Combines recent and long-term data for stable "Time Remaining" estimates.
📊 Advanced Graph Analytics Visualize your battery life with high-resolution timelines:
• Today View: 24-hour breakdown of your power usage.
• Since Last Charge: Dedicated tracking from the moment you unplug.
• Weekly History: Long-term trends to identify battery degradation.
• Screen-On vs. Idle Impact: Monitor exactly how much your screen usage affects your battery.
• Night Drain Detection: Deep analysis of power loss during sleep (11 PM – 7 AM).
⚡ Charging Intelligence Understand your watch’s charging health:
• Live Charging Speed: See charging rates in % per minute.
• Classification: Automatically detects Fast, Normal, or Slow charging states.
• Charge Cycle History: Tracks last full charge duration and average charges per day.
• Time to Full: Accurate countdowns until your battery is at 100%.
💯 Daily Performance Score Get a simple 0–100 Health Score based on your watch's daily behavior, including drain speed, temperature stability, and charging patterns. Know at a glance if your battery is "Healthy" or if you need to "Check Tips."
🌡 Hardware Health Monitoring
• Temperature Tracking: Avoid overheating with live thermal monitoring.
• Voltage & Health Status: Real-time hardware diagnostics.
• Smart Alerts: Get notified when battery hits 20% or 10% to prevent unexpected shutdowns.
🎯 Designed for Wear OS
• Watch-Only Power: Operates 100% on the watch with no companion phone app needed.
• Rotary Support: Navigate through graphs and stats smoothly using the digital crown.
• Optimized UI: Clean, high-contrast dark mode design tailored for round watch faces.
• Battery Efficient: Engineered to monitor your battery without becoming the cause of drain.
⌚ Watch Face Complications Bring Guardian's intelligence to your favorite watch face. Display battery percentage and predicted remaining time at a glance.
🚀 High-Resolution Real-Time Tracking I have overhauled tracking engine for ultimate precision.
• 1% Change Triggers: Graphs now update on every 1% battery change for real-time accuracy.
• Robust Background Monitoring: A new centralized engine ensures data is captured consistently even when the app is closed.
• Instant 'Since Last Charge' Resets: Discharging history now resets the moment you unplug, giving you a clean look at your current session.
Wear Battery Guardian is built for users who want total visibility and control over their smartwatch’s power life.
