GPF Battery Health

Track battery health for your Apple devices. Estimate long-term degradation from usage habits and charge limits (80–100%) in a clean, minimal interface.

GPF Battery Health helps you estimate and monitor long-term battery degradation across your Apple devices using a structured, data-driven approach.

Instead of relying only on system battery percentages, the app lets you model how daily usage habits and charging strategies affect battery health over time.

KEY FEATURES

• Add multiple devices (iPhone, iPad, Apple Watch, MacBook, Other) • Set charge limit preferences (80%–100%) • Define usage intensity (daily depth of discharge, charges per day) • Track optional known cycle counts • Simulate estimated annual degradation • View projected effective capacity over time • Clean, minimal, professional interface

The app is particularly useful if you use features such as the 80% charge limit available in recent iOS versions and want to understand its long-term impact.

HOW IT WORKS

Battery degradation is estimated using usage patterns you define: – Average daily depth of discharge – Charging frequency – Charge limit behavior – Thermal stress factors

Based on these parameters, the app provides: – Estimated equivalent full cycles per year – Estimated yearly degradation – Projected effective capacity – Overall battery health outlook

IMPORTANT

This app does not access private system battery data and does not read real-time battery diagnostics. All results are mathematical estimates based on the information you enter.

GPF Battery Health is designed for users who want a clearer, more analytical understanding of how their charging strategy may influence long-term battery performance.
