This app isn't in any of our charts yet.
Added : Temperatures and chargers. • While charging, see what your charger is actually delivering: watts, current and voltage. • New Temperature card: battery, processor, graphics, surface and charging port (where your phone shares them), and how much the battery warmed since you plugged in. • Optional temperature alarm that rings at the level you pick. • Test your chargers: a 3-minute measurement you can compare in History.
Live battery current, watts & health tracking. No ads, no account, no cloud.
Battery Monitor shows you what's actually happening to your battery, right now — not just a percentage. WHAT YOU SEE, LIVE • Real-time current draw (mA) and power (W), with a charging-speed badge (Trickle / Normal / Fast / Turbo) • Battery temperature and device thermal status • Time-remaining estimates — combined, screen-on, and screen-off — built from your own charge history, not a generic curve • A single adaptive gauge that reads Charging, Discharging, or Topped Up (recognizes OEM charge-limit features like Samsung's Protect Battery, instead of just looking "stuck") BATTERY HEALTH, TRACKED HONESTLY • Capacity estimate vs. your phone's design capacity, from a rolling average of your last several full charge cycles — with implausible sessions automatically filtered out • Daily / weekly / monthly charge-cycle history • Practical, non-alarmist tips on what actually slows battery wear (heat, voltage range, full discharges) — not fear-based "your battery is dying" messaging ALERTS THAT RESPECT YOUR ATTENTION • Custom charge-level alarm — drag the marker on the gauge to set it • High-drain alert only when current draw is well above YOUR historical average (not a fixed, one-size-fits-all number) • Overheat warning while charging PER-APP USAGE (OPTIONAL) See which apps you actually spend screen time on, with an estimated battery share apportioned from real discharge data. Requires manually granting Usage Access — clearly explained in-app, and entirely optional. BUILT DIFFERENT ON PURPOSE • No ads. No account. No cloud sync. • No internet permission at all — this app cannot phone home even if it wanted to. Everything is calculated and stored on your device. • One adaptive screen instead of separate charging/discharging tabs — you're never doing both at once, so we didn't make you flip between two views. • Available in 12 languages. WHY TRUST THE NUMBERS Battery Monitor reads directly from Android's battery and power APIs — the same low-level data your OS itself uses — and is upfront in-app about where it's estimating (like per-app battery share, since Android doesn't expose a true per-app battery API to normal apps) versus measuring directly. Battery Monitor is built for people who want to understand their battery, not just be told a percentage.
