Ipod 5.5gen/settings/Battery: Which mAh value?
surfer:
There is a difference in battery vapacity between the ipods of the 5gen and 5.5gen.
Which mAh value should i set in rockbox/general settings for my 5.5gen battery?
AlexP:
To be honest, it doesn't really matter. The battery capacity is only used on these players to estimate the remaining runtime (not the battery %), which isn't very accurate on them anyway.

It is accurate enough.

There is not.
There is a difference in battery capacity between the 30GB models and the 60/80GB models.

If you downloaded the right version for your player it should default to the correct setting. If you have changed the default setting google is your friend.
IIRC 30GB = 400mah and 60/80GB = 640mah.

This depends on your battery and what you consider accurate enough. Anyway, I was just explaining that the battery capacity only matters for runtime estimation, and not for anything else.

thanks for you answers!
Ok, i probably misunderstood some hints on the internet about the impeoved battery life in the newer "5.5 gen" Ipod comparing to the "5 gen". I found an article now explaining that a little more in detail:
--- Quote ---According to my source for some of this information, there are two reasons for the improved battery life in the 5.5G iPods: better power management software in the firmware, and lower power consumption by the new displays. I.e. even though the new screens are brighter, they are more efficient.

But my question here was in fact about this "estimation" of the remaining runtime, and even if it surely cannot be exact it still remains a good estimate about how much time you still have before having to charge again.
And it does make a difference if you set this value with, let's say, 300 or 600mAh.
