Ipod Gen 4 battery life... Anyone done any tests yet

[kunwar]

Hi
I was wondering if anyone has done any tests yet on the battery life for the new version.

It would include stand by time where the Ipod is not turned on for a while, while the player is running in shuffle mode where the cache is accessed a lot.
with lights on the display turned off etc.

Any figures would be interesting

cheers

Funny you mention this now, I'm just charging mine up to do a battery life test today! I'm going for max life, I will just select music, artist, all and hit play, 60% volume, driving a set of Ety ER4P's, and we'll see how long it goes for.

I have not done a super scientific, double blind, control group with placebo test but......

I use mine every day feeding a set of portable speakers and also with headphones to and from work.

Using a playlist and at about 50% volume I got 11 hours and 12 minutes as a best time.

I did not set out to try that; usually I just turn it on at the begining of the day and turn it off at the end which is usually about 9-10 hours. The good news is that it is much better than my 3g which usally lasted about 6.5 hours doing the same thing

Ok, it just shut itself down, again I played it at 60% volume, VBR mp3's, continuous playback (no track shuffling or searching) driving Ety ER-4P's for 13 hours 23 minutes!

Holy! I wanna buy it now!

How does the sound quality compare to NJB3?

The 3G iPod's quality (via HP or Line) wasn't a whole lot different to the NJB3, only there was less adjustability on offer. It looks like they've cracked the problem with the 4G. Time will tell I guess...

LOL, using the exact same parameters I got 11 hours 14 minutes. My files are encoded at 192 AAC. 50% volume driving ER4P's, backlight off, and sitting on my desk all day untouched.

is response time any worse though? they say that they achieve the battery savings via better cacheing. well, one side- product could be reduced response time. for instance, the iriver mp3 cd players, in the 1.00 version of firmware, it was fairly responsive, but in later versions, which redid the cacheing algorithms for longer battery life, it would be 1-3 seconds slower.

Not that I have noticed. If anything response time seems a tiny bit faster.
