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.

Results

iPod G2  
  16h 03min     MP3 (lame 3.97 --preset standard, ~200kbps) 2007-08-04 20GB model, Newertech 1600mAh battery, new PP5002 init without DEV_EN2
iPod G3  
  4h 03min     MP3 (192kbps cbr encoded with iTunes 6.0.4.2, QuickTime? 7.0.4) 2010-02-14 40GB model, 2-yr-old iPodJuice.com/milliamp 1100mAh battery. first test: i charged for a few hours using the apple firmware, tested on rockbox firmware. here are the results for that test: AndrewEngelbrecht_3G_apple-charged.txt The unit peaked at 4.096V and lost power around 3.722V.
  3h 59min     MP3 (192kbps cbr encoded with iTunes 6.0.4.2, QuickTime? 7.0.4) 2010-02-16 40GB model, 2-yr-old iPodJuice.com/milliamp 1100mAh battery. second test: i charged using the rockbox firmware for 12 hours. i fumbled around with the menus so i wasn't as efficient at starting the test, so that might be why the results show that the initial charge didn't peak as high: AndrewEngelbrecht_3G_rockbox-charged.txt Unit peaked at 4.055V and powered-off at about 3.710V.
