Ipod Battery Runtimes

Introduction

This page documents runtime tests performed by Ipod users. The intention is to test the efficiency of the different decoders operating on differently encoded input files.

For test methodology see BatteryRuntime

For comparison with the Apple firmware, see Apple's guide to Accurately determine your iPod battery life.
