That's actually so low imo. It just plays music and doesn't connect to internet right? Should last for like a week at least.

20 hours of playback. Not 20 hours of idle.

Hmm if it's 20 hours of constant playing then that's much better

It needs a serious optimization. iPod Nano 7 lasts 30 hours with a 240 mAh battery. So with 2200 mAh, it should last like 10 days at least.

Ipod shuffle lasts 12 hours with an even smaller battery

It has a 150 mAh battery, so even with Shuffle's optimization level, 2200 mAh should still last more than a week for Tangara. I gave Nano 7 as an example because it's what I have. Of course I'm not expecting Apple level optimization but they can do much better. Otherwise 2200 mAh is an overkill for such a device.
