Description
BAST – Your Battery Diagnostics Companion
BAST is a powerful and easy-to-use battery diagnostics tool that gives you deep insights into the condition of your iPhone, iPad or Apple Watch battery. Using Apple’s own analytics log files, BAST extracts and analyzes key data to provide detailed information, including:
- Device and operating system details
- Battery health (even values above 100%)
- Charge cycle count
- Current, maximum and minimum battery capacity
Apple Watch is supported automatically if paired with the same iPhone.
Simply import the analytics file — BAST will guide you through every step.
A built-in manual explains the process clearly and helps you get started right away.
