Meet Volt, your AI battery advisor: tap a question about your own battery and get plain-language advice built from your real health and charging data. No fake "boosting," no killing apps. Just the truth about your battery, and simple habits to make it last longer. 🤖 ASK VOLT — YOUR AI BATTERY ADVISOR (BETA) Tap a question — "Why is my battery draining fast?", "Is my charging habit healthy?", "When should I replace my battery?" — and Volt answers in clear, jargon-free language, personalised to YOUR battery health and charging history. It explains what your data means and suggests small habits that slow long-term wear. AI guidance can occasionally be imprecise, so every answer carries a clear note and a one-tap way to report it. Plus an optional weekly battery report, delivered automatically (Pro). 🔋 WHY POWER BATTERY IS DIFFERENT Most "battery saver" apps promise to magically extend your battery by force-closing apps. They can't, and they don't. Power Battery takes the honest route: it measures what's actually happening to your battery and helps you build charging habits that genuinely slow long-term wear. 📊 SEE YOUR REAL BATTERY HEALTH • Live dashboard and charge meter: level, temperature, voltage, current flow (mA) and live power draw in watts (W) • Battery health % with estimated capacity (current mAh vs. design mAh) • Real charge-cycle count — read straight from your device on Android 14+, estimated from your history otherwise, always labelled so you know which • Time-to-full and time-to-empty at a glance 🌱 MAKE IT LAST LONGER • Wear prediction: projected days until replacement, plus your wear trend over time • Care insights (Pro): a 0–100 habit score from heat exposure, time held at high charge, and deep-discharge episodes • Screen-on vs screen-off drain: see how much battery your display uses versus standby • Personalised tips that turn your data into habits that extend lifespan 🔔 NEVER OVERCHARGE AGAIN • Charge-limit alarm (Pro) with a full-screen lock-screen alert when you hit your target (e.g. 85%) — so you stop topping off to 100% • Standard alerts for full charge, low battery, high temperature and high voltage ⚡ STAY AHEAD OF PROBLEMS • Speed test: live charging and discharging rate with fast / moderate / slow classification • Connected devices: see the battery % of paired Bluetooth earbuds, watches and speakers • History + graphs across 1h, 6h, 24h, 7d and 30d (Pro) 📱 WIDGETS & AT-A-GLANCE • Home-screen widgets in small, medium and large sizes • A dedicated connected-devices widget • Follows your system light or dark theme; Pro adds Light, Dark and Material You themes • Available in 10 languages ⭐ FOR POWER USERS (PRO) The core app is free. Pro unlocks unlimited AI advisor chats, detailed graphs, the charge-limit alarm, Light, Dark and Material You themes, unlimited history, CSV / JSON export and priority support. Whether you want a precise battery monitor for everyday battery management, a way to track charge cycles and charging speed, or an AI advisor that reads your real battery data — Power Battery gives you the facts. Permissions, plainly: Bluetooth reads the battery level of your connected devices. Notifications power your charge alarm and battery alerts. Your battery-health summary is sent to a secure AI service only when you ask Volt a question or turn on the weekly report — never sold. --- Source: https://storetally.com/android/com.devstudioworks.powerBattery.pro As of 2026-11-13, from the StoreTally census.
