OK, now this all sounds not THAT impressive somehow. 25% Power drain if we only put a little Mouse onto the Pandora? Hmm, sounds really much. 10h Gameplay is OK, I thought at 200MHz (Picodrive for example"] it could be at least 15-20h. 100h mp3-play was of course one of Craigix many marketing gags but I hoped for at least 25-50h mp3 playing. ^_^
It makes perfect sense to me.

Craigix always said "about 10 hours", so I don't know why you'd expect 15-20h[/quote]
A search engine in the wrong hands is a terrible thing
We've probably all said things we shouldn't have, or wish we could take back later, but people read what we say and, in many cases, base later thoughts, assumptions, and even orders for goods on it. At:

We have decided to stick to 27mm and a custom battery size to use every last mm of space, the battery will be ~4000mah.
According to our calculations it should work for
up to 100 hours(!"] playing mp3s. We won't know about using powerful apps until we do some further tests, but we are aiming for that magic 10 hours.
It should easily get 10+ hours running recompiled GP2X apps[/quote](I have underlined for emphasis)
Much "Gosh, WOW, OMG I want to have Craig's children" and math based on speculation given plus users experiences of 40 hour life of an iPod batter ensued. Whilst there were a few calming words from users, the general take (esp. before the thread was closed by a mod) seemed to be that this was a fantastic but credible bit of info.
This was, of course, in March last year. Perhaps before people upsized the amount of salt needed to be taken with each excited pronouncement by Craig, but still - that's where the 100 hour rumour comes from, and why people may have downsized that to a more realistic 15-25 hours to take marketing b... err, excitement into account. I think those who reckoned we could be getting less than 6 hours use out of the Pandora under any reasonable load ("reasonable" including IMHO a mouse and better keyboard but not, say, an external hard drive) were very much in the minority.
6 hours is likely to be ample for me (if only because my MP3 player is already dinkily portable and lasts forever on a single charge).
To make it complete, here is the appropriate quote from MWeston:

This is sort of the idea I had in mind when suggesting to Craig we could get 100 hours of battery life just playing music.
What I thought would be ideal is to suspend Linux to SDRAM and then put the external memory to sleep. Then, using the internal scratch pad RAM, and maybe using the DSP core and its RAM, a low power, low speed music player could be run to just play music and use the shoulder buttons to change tracks. It would be pretty basic, but most of the time, I don't even look at the display when playing music. I just put the player on random shuffle so this seems like a great idea for when you don't need any of the Pandora's other capabilities.
The alternative is to see just how little power we can use with the screen off, unnecessary features powered down, the clock speed reduced way down to whatever minimum keeps required external interfaces working, and still running Linux (since it has so many codecs supported already). This will take a while to master because I don't think current OMAP3 kernels even turn Smart Reflex features on yet.
If you look at Nokia's IT lineup you will see that OMAP is an incredibly efficient little beast. It will be possible to squeeze an impressive battery life out of 4000mAh. Just let the software mature and let the hackers do their magic
