Android Battery Health | Phonecheck Help Center
Battery health is calculated using the most reliable data your device provides, with automatic validation to ensure accurate results across different Android models.
How We Determine Battery Health on Android
We calculate battery health using a tiered evaluation process designed to be accurate across different Android manufacturers and device models. Battery health is calculated using the most reliable data your device provides, with automatic validation to ensure accurate results across different Android models.
What this means for you
-
We use manufacturer-supported signals whenever they’re available.
-
If a device doesn’t expose a single definitive health metric, we safely derive one from reliable system data.
-
Our approach ensures consistent results, even when Android devices report battery information differently.
Our Approach
-
Primary evaluation: We first check for native battery health indicators provided by the device or manufacturer.
-
Secondary evaluation: If a direct health value isn’t available, we calculate battery health using validated usage and charge data.
-
Final validation: When needed, we cross-check results against low-level battery telemetry to ensure accuracy.
Result
The battery health value you see:
-
Reflects the current condition of the battery.
-
Accounts for normal battery aging.
-
Is tailored to how your specific device reports battery information.
