N13 Battery Warrior - Charge & Drain Tracker

Understand how your device battery performs, not just how much charge is left. Battery Warrior tracks charging sessions, battery drain, historical usage, average daily consumption, and estimated time remaining. It runs automatically in the background and turns raw battery data into clear, useful information. ## GLANCE VIEW See the essential information directly from the widget carousel: * Current battery percentage * Drain rate in percent per day * Charging status * Date of the last recorded charge ## MAIN DASHBOARD Open the widget for a complete battery overview. * Since Charge: Time since the last charging session ended * Avg. Daily: Average drain per day for the selected history period * Last Charge: Duration of the most recent charging session, when known * Empty In: Estimated time remaining before the battery reaches 0 percent The circular battery indicator changes colour when the battery falls below your selected warning threshold. ## BATTERY HISTORY Review battery trends using clear 7-day, 14-day, and 30-day graphs. Each graph shows the minimum and maximum battery levels recorded during the selected period, helping you identify unusual drain, charging habits, and changes in battery performance. Battery data is normally sampled every 30 minutes. Useful graph data usually appears after one or two days, while drain estimates become more stable after several days of normal use. ## AUTOMATIC CHARGE TRACKING Battery Warrior detects charging automatically. On supported devices, it uses charging status information to detect when charging starts and ends. It can also identify charging events from battery increases recorded between background samples. When the exact charging duration cannot be calculated reliably, the widget leaves the value unavailable instead of showing an inaccurate result. ## AVERAGE MODE Choose the history period used to calculate battery drain: * All History * Last 7 Days * Last 14 Days * Last 30 Days The selected mode applies to both the main dashboard and the glance view. ## ESTIMATE MODE Choose how Empty In is calculated: * Hourly: Uses the recent drain rate since the last charge * Daily Average: Uses the selected historical average ## DRAIN WARNING An optional warning indicator appears when the calculated drain exceeds 50 percent per day. This can help identify unusually high battery usage, incomplete history, or an unreliable short-term calculation. ## CONNECT IQ SETTINGS Available settings include: * Battery warning threshold from 5 percent to 50 percent * European, US, or ISO date format * Average Mode * Estimate Mode * Optional information screen when the widget opens ## DISPLAY SUPPORT Battery Warrior adapts its colours for supported display types. * AMOLED: Darker, muted colours to reduce unnecessary brightness and lower burn-in risk * MIP: Higher contrast colours for improved outdoor visibility ## GETTING STARTED A value of -- means there is not enough recorded data yet. * Initial values normally appear within one hour * Useful graphs usually appear after one or two days * More stable drain estimates normally require about three days Battery collection resumes automatically after the watch is restarted. Battery Warrior gives you a clear and practical view of how your watch battery charges, drains, and performs over time.

v1.8.3 * Added a new 1-day battery chart before the existing 7-day view. * The daily chart shows battery history from 00:00 to 22:00 using 12 two-hour time positions. * Added visible sample points to make daily battery changes easier to follow. * Daily chart boundaries and sample placement use local calendar time, including daylight-saving transitions. * Graph navigation now follows this order: 1 day, 7 days, 14 days, and 30 days. * Added support for a wider range of MIP and AMOLED devices.
