GPF Battery Health

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.
