How do I use my iphone? Is my battery dying and ripe for replacement? Would it make sense for me to get an external battery pack? BatteryLogger Lite answers these questions and more by logging the battery-state on every change, and presenting the results in graphical plots. In contrast to the only logging program currently in the app-store, BatteryLogger has been designed for efficiency and scalability, allowing to store a virtually unlimited amount of datapoints, and view results for any period in the past.

Tip: Use the backgrounder application to run BatteryLogger in the background & log every change in battery-level.

There is a paid pro-version in development. The pro version will have the following advantages over the free version: - logging daemon: Even log when the program is closed! - battery load-cycle plotting and counting. (Check apple's battery wear & tear claims!) - Improved lay-out - No Ads - Additional statistics, including: Total time on, time charging, time in-use, time sleeping, and time switched off.
