HD-NW3 30 hours? hell no!!

Thread Starter 
I've just bought a new DAP: Sony NW-HD3.
It's says on the box 30 hours of playing.
It doesn't even get near to 15 hours of playing...
I'm trying to save energy by disable the backlight while daylight.

Is there something bad with my unit?

Do I need to turn off the battery when I'm not using the DAP?

that 30hrs is with sony's atrac format. normal mp3s should be about 1/2 that, maybe a little more. id say 15hrs is pretty normal if youre skipping tracks, ect.

I'll do a little test in a few days to check how much time does this DAP work with mp3....
I think I'll convent my mp3 to atrac, no matter what will be the results (If that means batter battery life).

And when using recheargable batteries you need a few charging cycles before they live up to their potential.

30 hrs is under "ideal" conditions. Music recorded at atrac3plus 48kbps, no scrolling, slightly cold temperature. I have one piece of advice, DO NOT DROP IT! I had the HD1 and dropped it on the bathroom floor at school. The hard drive stopped spinning and the screen cracked, compusas replacement warranty covered it thankfully. If you want good battery life though the HD1 is a better choice over the hd3, supposedly they are rated for the same time, but the hd3 dies out before the hd1.

You're right, its no where near 30 hrs. I own an HD5 and I think I'm getting around 12-15 hrs. Most of my songs are above 192kbps mp3s and I use the menu very often. Nontheless, it definitely lasts much longer than the iPod. I only need to charge my hd5 once a week (sometimes once two weeks) under normal usage.

About 22hrs with my old HD3, Atrac 256, volume 20, no EQ

Only good thing about it mind. Bless eBay

idk guys... i can get around 20 hours with mp3, eve VBR up to 320 kbps sometimes. i do know that i did about 18 hours of bus traveling last month and never recharged my nw-hd3. there was about a week in between each 6 hour segment of the bus trips as well.

ive also got the new sony ericsson w600i phone which is supposed to have something like 15 days standby, and 9 hours talk. listening to music on the phone drains it the fastest but if you dont listen to any music the battery seems to last forever.

sony is the best when it comes to battery life in my experience.

Just to recap what everyone else has said (and get my post count up!), battery life tests are always done under ideal conditions. If you use 48kbps files rather than 96kpbs, the player can buffer twice as much music at a time, and hence the hard drive doesn't need to spin up nearly as often. Which results in longer battery life.

Also, they'll just leave it on continuous play, rather than skipping or rewinding tracks, which can also involve the hard drive spinning up.

IIRC, ogg takes up a lot more battery life, as the codec uses a lot more processing power to convert to sound (or something - it uses floating point algorithms).

For what it's worth, I had an HD3 and was very impressed with the battery life - I'd top up the charge about once a fortnight, which would usually mean about 12 hours. The battery generally wouldn't be empty at that point. On my HD5H, however, skipping through tracks takes quite a lot of battery life...

So you guys suggest that I'll convert all my mp3 to atrac and the bat life will grow?
One more thing, do I need to turn off the bat when I'm not using the DAP?

No you don't need to turn off the battery... I don't think it's drained to any noticeably extent when it's off. What you'll have to do to get maximum battery life is to convert your MP3's into 48K or 64K ATRAC3+ files.

Does (8K or 64K ATRAC3+) = (128K or 196k mp3) ?

I'd say 64K ATRAC3+ is better than 96K MP3 but a bit worse than 128K MP3. Somewhere in between.

I don't think so. I remember when I had my iAudio G3 it had a 30+ hour battery life for mp3 files.
