About this app

Power Battery is the honest way to know your battery's true health — and now you can just ask. 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.

🔋 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: 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 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

📱 WIDGETS & AT-A-GLANCE
• Home-screen widgets in small, medium and large sizes
• A dedicated connected-devices widget
• Material You theming with dark and AMOLED modes
• Available in 13 languages

⭐ FOR POWER USERS (PRO)
The core app is free. Pro unlocks unlimited AI advisor chats, detailed graphs, the charge-limit alarm, custom + AMOLED + 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 — never sold.
