iPod Touch Battery Test #1
Friday, February 12th, 20102010-02-12: Day One
08:07 AM: So, I’ve completely recharged my 1 week-old iPod Touch, 64 GB portable player, and I want to see how long it will play an Internet radio station through wifi on a single battery charge.
08:08 AM: During the test, I will not activate the screen more than absolutely necessary to keep it playing; it will just sit here on the counter, playing in screen-lock mode. Thus, the play time we get on the Touch might be longer in this “bench test” than one would get under actual usage conditions.
08:10 AM: On your mark, get set, go! I just started the iPod Touch playing KYW News Radio, and we’ll see how long it runs before going dead. KYW is a 64 kbps AAC stream, and I’m running the Touch in the same room as my wifi access point for the most reliable wifi connection. Stand by…
08:40 AM: The Touch just stopped playing, apparently due to a small interruption in the Internet connection between it, and KYW. So I had to activate the screen to press the play button again. It’s playing once again without difficulty. The test continues…
09:13 AM: Another momentary interruption that required manual intervention to correct. I noticed that the battery indicator still says that it’s fully charged. An hour and three minutes into the test now…
09:50 AM: Another interruption. Restarted. Battery indicator still says FULL.
10:25 AM: Another drop-out. Restarted. Battery indicator still says FULL.
10:25 AM: Another drop-out. Restarted the KYW station play. Battery indicator has started to drop; there’s now a thin black line at the right edge of the picture of a battery at the top right corner of the screen. Looks though like it’s still around 90 percent full.
11:55 AM: Another drop-out. Restarted. Battery indicator still says roughly 80 percent.
12:30 PM: Another drop-out. Restarted. Battery indicator still says roughly 80 percent.
12:30 PM: Another drop-out. Restarted. Battery indicator still says roughly 70 percent.
02:25 PM: Several stoppages occurred over the past couple hours and I restarted play, probably within ten minutes of each incident. But the iPod Touch is still playing and the battery still has approximately 60 percent charge left.
04:10 PM: Well, the iPod Touch is still going. Batttery level is now around 40 percent, and we’ve been running this test for eight hours now.
08:10 PM: It’s still playing. The battery looks to still have around 30 percent charge. However, over the past four hours, I’ve had to restart play numerous times. Not sure if it’s that station, the Internet, my network components here, the software, or the iPod Touch itself. These all-too-frequent cut-outs surprised me. Perhaps I’ll try the all-day-play test from a laptop running Winamp and see if it stops at all like the iPod Touch did today.
09:44 PM: A low-battery warning dialog box just appeared on the iPod Touch screen. The battery is now at 20 percent.
11:10 PM: The iPod Touch is still playing and the battery indicator shows about 20 percent charge still left. So far on the current charge, it’s played for 15 hours. However, I’ve run out of steam before the iPod did to night. So I’m turning it off now and I’ll run it out the rest of the way tomorrow. See those details below, in this same post. I’ll add them as they become available.
2010-02-13: Day Two
10:00 AM: Turned the iPod Touch back on again and resumed play of KYW News Radio. I did not charge the battery overnight. So far on this charge, the Touch has played for fifteen hours and zero minutes. We’ll add to that today.
11:00 AM: Well, the iPod Touch finally went dead. Thus, the battery lasted 16.0 hours on a charge. Pretty good, particularly since I ran wifi on it, which consumes extra energy above what’s used when just playing local music files. I’ll add a summary of the test to this post a little later.
11:05 AM: Now, I’m plugging the iPod Touch into the charger; I’m curious how long it will take to completely recharge this dead battery. Stand by…
