Battery Guardian APK for Android

Experience continuous battery telemetry: percentage, health, temperature, voltage, and a 90-day charging history while receiving configurable charge and temperature alarms. Sidtastic Tech built this Android utility to keep monitoring local battery data without online access. It records real-time stats, keeps a persistent notification for uninterrupted monitoring, and stores a 90-day log with custom alert thresholds and adjustable low-battery warnings. The app targets privacy-conscious Android users who want technical battery stats and safeguards without accounts or uploads.

Local telemetry covers the technical battery parameters you need

The app reads percentage, health, temperature and voltage in real time, and exposes battery technology and status. In addition, the tool maintains a 90-day charging history so you can spot recurring drain or charging patterns. A persistent notification keeps the monitoring service active, and the history log timestamps charge events so trend inspection is straightforward.

The monitoring approach keeps resource use to a minimum

The developer describes a lightweight footprint, and the app runs via a persistent notification to avoid being killed under memory pressure. In practice, the design keeps background activity confined to telemetry collection and alert checks, which suits both budget and flagship devices. Moreover, continuous monitoring remains available without constant foreground activity, reducing visible battery and CPU impact.

Privacy and safety are enforced by local-only operation

The app operates 100 percent offline and requires no internet permission, and the developer states zero data collection and no account sign-up. All alert processing and history tracking occur locally on the device. Safety features are notification-based: custom alarms warn of full charge, low battery, and overheating, but the app lacks system permission to interrupt charging hardware.

Simple presentation with adjustable thresholds for nontechnical users

The interface is described as clean and straightforward while still letting users set custom thresholds for full charge (for example 80, 90, or 100 percent), low battery, and high temperature alerts. Casual users can rely on default alarms, and more experienced users can tune thresholds. Despite the configurability, actions remain manual after alerts: you must unplug or otherwise respond to notifications.

Practical, privacy-focused battery monitor with a single operational limitation

Battery Guardian suits privacy-minded Android users who want local telemetry, a 90-day charge history, and configurable alarms; it keeps monitoring work constrained to the device and avoids data uploads. The single clear trade-off is operational: the app only notifies you of overcharge or overheating, it does not stop charging automatically, so users must act on alerts to prevent degradation.
