5 Hour Battery Test
I left the iPod touch 5th generation on for 5 full hours by setting the Auto-Lock option to Never. During the entire 5 hour time the WiFi was left ON and the screen brightness level was set to approximately 1/3.
Mostly I read via the Kindle app. I also was in and out of a few other apps. I spent about 20 minutes watching streaming TV via the Time warner Cable app. I spent another 20 minutes watching a movie that was previously DLed via iTunes.
Battery drained only 40% going from 100% down to 60%.
I'm extremely pleased with the battery discharge time. I own or previously owned the 1st, 3rd, and 4th generation iPod touches. None of these earlier models held a charge very long, and the 4th generation was really bad about discharging in around 3 hours. The 5th generation has obviously been greatly improved and I estimate it will keep a charge all day (10-12 hours) based on my first 5 hour test.
