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.
Live battery current, watts & health tracking. No ads, no account, no cloud.
