iPod mini Battery Question

<< < (3/4) > >>

Even if that was so, it should be much more improved because of the compact flash card inside.
The battery itself is not old, for it was recently purchased. I could try a benchmark, but is there an acurate meter for the iPod? I believe it was percieved that the rockbox meter was lacking? To do the benchmark, do I:
Put it at full volume?
Play a file at what format, what filesize, and and what bitrate?
Keep headphones on it?

Thanks.

Probably doesn't matter much, just leave it at a reasonable volume.

> Play a file at what format, what filesize, and and what bitrate?
Might matter a little (but from what I understand, not much), just pick something general (mp3s or something) or have it loop through your collection.  I haven't seen a standard pick for this.

> Keep headphones on it?
Probably.

One thing you want to be careful of:  the backlight on all of the players that I know of is /very/ battery intensive.  You don't want to be pushing buttons all the time or else the backlight will keep coming on and could mess up your results.

If you're trying to compare the OF to rockbox, just be consistent between the two and you can't really go wrong.

And the most accurate meter for comparison is likely to just be: run it until it runs out of power, from a full charge.

BatteryRuntime for info on running a battery runtime test.  I'm not sure if battery_bench will work properly on your CF mini or not.

Thanks for the plugin. I'll post my results when I get them.

Personally, I think the Ipod Runtime page is also worth looking at, especially the most recent tests.  I believe it is the runtime page with the most pedantic attention to detail.

Two - a 750mah iPod mini battery is 50% larger than stock.  In my experience (take that with as large of a grain of salt as you wish) the larger the Li battery is versus stock the less reliable it is.
