I've bust my mp3 player now, and thought I'd kill two birds with one stone and get the Nokia 101, just 999 in BigC with MP3 player. I'm not sure what kind of battery it comes with. I heard rumours it's +1000 mah in Europe but the cheap Asian version has an 800 mah. Question is, how much juice does just playing music use, how many hours on one charge do you think?

According to Nokia's various websites (Europe, Asia-Pacific) the 101 has a BL-5CB 800 mAh battery everywhere.

I think it would be challenging to estimate the number of hours of playing time other than to say it should be less than a typically MP3 player. If it has the ability for "airplane mode", turning off the mobile phone transceivers, then it might last longer.

This website seems to indicate that the 101 does indeed have a 1,020 mAh battery available, maybe you buy a second one as back-up? And it has music playing times (26 hours for the 800 mAh battery):

Battery Power 1020 mAh (for India, China, Bangladesh, Sri Lank and Nepal) or 800mAh (for the rest of the world) USB Charging yes Music Playback Time 1980 for the 1020mAh version, 1560 for the 800mAh version minutes

My personal rule is to keep 2 backup batteries, for long trips etc.

Don't buy batteries from street vendors, it could turn out they are not even batteries. Check the prices in places like Big C.

Thank you, these are great answers! Of course, check the price of a spare battery where I buy it. Why didn't I even think of that.

But the estimated time on an 800mah, is 1560 or something, if that's minutes, it's 26 hours. Even if that was a generous estimate, it ain't bad. Thanks for the link.

OK, went to big C. They opened one up for me. It's an 800mah. They said they don't sell batteries, but directed me to JMart, who said 299 for a spare. Not too bad really.

Yesterday, I was assuming talk time would consume about the same power as mp3, though not sure if that's actually the case.
