About this app

The whole story, the way it reads on Google Play.

Battery Health Monitor helps you understand, track, and improve your battery health with clear insights and tips you can act on.

Real-time battery dashboard

Your battery level, charging status, temperature, uptime and estimated time remaining, all at a glance.

Charge history

Every charge session is logged automatically, so you can spot the habits that wear your battery down.

Achievement badges

Earn badges like Good Start, Perfect Week, Night Owl and 80% Master as your habits improve.

Smart notifications

A nudge when you reach 80%, the best place to stop, and a warning when the temperature climbs past safe limits.

Dark mode

A dark interface that's easy on the eyes.

Why battery health matters

Lithium-ion batteries wear out over time. Overnight charging, deep discharges and heat all speed that up. Battery Health Monitor coaches you toward better habits so your battery lasts longer.

No account required. All battery analysis runs on your device.

What it does

Three ways it helps you look after your battery.

Health score & grading

Your charging gets a daily A–D score, so you can see at a glance whether your habits are helping your battery or wearing it down.

Smart charging tips

Tips for keeping the charge in the 20–80% range, plus guidance on temperature, so the battery stays healthy for longer.

Battery detail analytics

Switch between 24-hour, 7-day and 30-day views to follow your charge cycles and temperature trends over time.

Questions people ask

Short answers to the things that come up most.

How do I check my battery health on Android?

Open the app — the dashboard shows health, temperature and charge state at a glance, and the Charge Score grades your charging habits A–D each day.

Do I need an account?

No. There's nothing to sign up for. Open the app and your battery data is right there.

Does my battery data leave my phone?

No. All battery analysis runs on your device. The only thing sent out is an anonymous crash report when something breaks, so I can fix it.

Why stop charging at 80%?

Lithium-ion batteries wear faster when they sit near 100% or get drained to empty, and faster still when they're hot. Keeping the charge between 20% and 80% slows that wear, and the app nudges you when you reach 80%.

What is the Charge Score?

A daily grade from A to D based on how you charged that day, with a breakdown of which habits helped and which ones hurt.

Is there an iPhone version?

No. Battery Health Monitor is Android only.
