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.
