AccuBattery

AccuBattery is an Android app for tracking battery health and performance. It estimates charge capacity in mAh and wear per charge cycle, and shows live charging and discharging details such as current, charge speed, and power use. The app records charge and discharge sessions along with estimated wear. A charge alarm can remind users to unplug at a chosen percentage. The free plan provides access to historical sessions for 24 hours. Premium is unlocked through an in-app purchase and includes an overlay showing battery current and CPU usage while another app is running; its plan description says the last 150 historical cards are currently shown. Per-app drain is assigned to the foreground app, so background activity may be attributed to it. App-usage-statistics access is optional, but some per-app details are unavailable without it. Some Android devices do not supply usable battery-current data, which can prevent capacity estimates and other dependent features from working. The maker is based in Rotterdam, Netherlands.

AccuBattery combines battery estimates, live measurements, session history, and a charge alarm for Android. Device data limitations and its foreground-app attribution are worth considering when interpreting estimates and per-app drain.

AccuBattery suits Android users who want estimates of battery capacity and wear, live charging information, or a charge alarm. Its usefulness for current-dependent estimates depends on the device supplying usable battery-current data.

Overview

AccuBattery is an Android app for tracking battery health and charging behavior, with estimates of capacity and wear alongside live readings and session history. It best suits phone owners who want a clearer view of how charging affects their battery. Its usefulness depends in part on whether a device supplies the current data the app needs.

Key features

AccuBattery estimates charge capacity in mAh and wear per charge cycle, then keeps a history of charge and discharge sessions. That makes it useful for spotting patterns over time, though the estimates depend on device data and should not be treated as a direct measurement of battery health.

Live readings show battery current, charge speed, and power use while the phone charges or discharges. The charge alarm can remind you to unplug at a chosen percentage, a practical way to follow a preferred charging routine. Android notifications and an in-app alarm provide the alerts.

Per-app usage assigns realized total battery drain to the app in the foreground. Background activity can therefore be credited to the app on screen, so these figures are better read as an indication than a precise breakdown. App usage statistics access is optional, but some per-app information is unavailable without it.

Some Android devices do not provide usable battery-current data. On those phones, capacity estimates and other features that rely on current readings may not work, which is a meaningful compatibility limitation for an app centered on battery measurement.

Pricing

Free: free. The free plan gives access to historical sessions for 24 hours, making it a fit for users who mainly want current readings and recent charging context. The short history window limits longer-term comparisons.

Premium: custom pricing, unlocked through an in-app purchase. Premium adds an overlay with battery current and CPU usage while another app is running, which suits users who want those readings during other phone activity. Its historical cards show the last 150 entries; the free plan's 24-hour history access and Premium's card limit are different constraints, so neither plan offers unlimited session history.

Platforms

AccuBattery is available for Android mobile devices. It is not a choice for monitoring a desktop or a different mobile platform.

Who it's for

Choose AccuBattery if you want charging alerts, session records, and estimated battery wear in one Android app, and your device supports the current readings those features use. Look elsewhere if you need dependable per-app attribution, since background processes can skew the foreground app's drain, or if your phone does not expose usable battery-current data.

Pros and cons

• Pro: Capacity and wear estimates paired with session history help users follow battery behavior over time.
• Pro: A customizable charge alarm supports users who want to unplug at a chosen percentage.
• Con: Current-dependent features may fail on Android devices that do not supply usable battery-current data.
• Con: Foreground-app attribution can make per-app drain misleading when background processes are active.
• Con: Free history is limited to 24 hours, while Premium displays only the last 150 historical cards.

Alternatives

GSam Battery Monitor is another freemium Android battery monitor; consider it if you want an alternative focused on Android, with a free plan that contains ads.

Paessler PRTG Network Monitor is a better fit for broad infrastructure monitoring across platforms such as Android, iOS, Linux, macOS, Windows, and self-hosted systems. Its free tier covers up to 100 sensors and about 10 devices, a different scope from tracking one phone's battery.

HWMonitor suits readers who want free hardware sensor monitoring on Windows as well as Android, rather than a battery-focused Android app.

ManageEngine OpManager is worth considering for monitoring network devices across several platforms; its free edition covers three devices perpetually.

Netdata is a free community option for system monitoring across desktop, server, and web platforms, with a limit of five active connected nodes.

NetXMS offers a free open-source monitoring solution across multiple platforms for readers whose needs extend beyond phone battery tracking.

XStat is a free option for hardware sensor access on Windows 10 or 11, requiring administrator rights.

Glances is a free, open-source system monitoring tool for readers seeking broader device monitoring, with some optional features requiring extra dependencies.

Verdict

AccuBattery is a sound choice for Android owners who want charge reminders and a record of estimated battery wear and charging sessions. Its combination of live readings and history is the main reason to choose it; device support for current data and the limits of foreground-app attribution are the main reasons to look elsewhere.
