yes but the SQ is weak.
what about mp3 vs ogg at same bitrate. I know ogg is not exactly CBR, but a VBR format.
I want to find the best compromise for battery and also get decent sound.
I just got my clip yesterday,ordered it online from the Sansa store.I guess I could have gone to Wal-mart…
This is my first mp3 player.It arrived with no charge.I hooked it up to the back of my computer and started charging and downloading through Rhapsody.Very easy to work with.Shut it off last night,and going to work today for about 7 hours…I will let you know how things work out! The charge right now says 100 % according to the screen.I am using the factory speakers and will be playing it about 3/4 volume.

Ogg Vorbis(it’s not just Ogg) will sound better than MP3 at those middling bitrates…and VBR owns CBR anyways. However, it does use a little more battery to play Vorbis than MP3, but it should be much less demanding than FLAC.
One thing though…it’s recommended to let the player charge fully before you start really using it. They ship it with a partial charge so you can take it out of the box and play for a few minutes, but then you should charge it fully. Also, turn your screen brightness down, and shorten the backlight time if you’re terribly concerned with max battery life. The KSC75’s do take a bit of power to drive, as you figured out. My FiiO solved that problem though.
I just played it a continuous 6.5 hours at 3/4 volume,and the screen shows half used,so thats good! The only problem I find is the speaker jack goes in and out when jiggled.I also found the lock button to be a real asset.Not bad for 50 bucks!
Yep i will order my Fiio E5 today to lower the output volume and get high output power from the separated amp.
I think i’l stick with OGG Q10 VBR 320-500kbps for near-lossless SQ.
I find the FLAC battery uptime decent - 15% drained per hour with highest volume setting.
When i get my Fiio amp i will review the playback time.

Hi there,
Just bought today a brand new 8gb clip.
I only managed to play 2 hours of music on it. Initial charge was about 80%. All my music is in flac format(~900kbps). Also my pair of headphones (Koss KSC75) are high impedance (60 ohm). I preffer high volume setting at about 90%.
How much battery playback time can i expect?
My battery level dropped in about 1h playback from 80% to 60%.
Only 5h of total playback time then? Should i change to an lossy format (for example ogg) and a pair of IEM’s to maximize the battery playback time?
Is the battery drain so high when playing lossless on high volume/impedance headphones? If so, about how much in comparison with a normal situation. Lets say all tracks at 128kbps mp3 at about 50% volume with standard headphones that came with the player.
I also have the new 8GB clip and find that I get about 6-7 hours of battery life when playing FLAC files (with Etymotic ER6iheadphones). By contast, by playing 128kbps MP3s, the battery lasts at least twice as long (around 14 hours). While I understand FLAC and OGG files use more power, is there any chance a firmware update can help to close the gap in battery life between playing MP3s and FLAC files? 6-7 hours is rather disappointing.
FLAC is a memory intensive because of the ‘huge’ file size and bandwidth needed to process. Anyway, i switched to ogg VBR q5 and i scored 10 hours+.
Lossless is a bad factor for battery life. What about wave format? (uncompressed).

I have a 1GB Clip. I mostly listen to recorded books as .WAV files at 64kbps and get about 10 hrs. on the battery, playing at max volume. Not to go off topic, but I have found that my clip recharges fairly quickly so that, even when 10 hours won’t get me through a whole day, a quick session with the charger seems to do the trick. As a result, I have stopped obsessing so much about battery /charge life as when I first bought the device, which is my first digital (non-CD) player.
N.B., I have to play at max volume because I don’t hear so well. I had bought a FiiO E3 to allow play at lower volume to extend battery life, but, on balance, simply recharging turned out to be less of a hassle. Now I only use the FiiO to play the Clip through a radio.
The thing limiting the Clip’s battery life is it’s diminuitive size. Small DAP=small battery. Considering how small the battery is, it actually does pretty well- but when I decide to upgrade from my 2GB Clip, I may just go for the Fuze or some other, larger player, that has a larger battery and thus gets substantially longer run time out of a charge.

Yes, join the ranks of those who have both Fuze and Clip. I’ve certainly enjoyed having both
I’ve had almost the exact experience. Got the wife a 1Gig from Wal-Mart and it works fine. Mine is a 2Gig from B&H Photo and the charge doesn’t last and leaks badly when not in use. Maybe I’ll replace it with a Fuse or a 1 Gig. I may ■■■■ and moan to Sandisk too.

hi all ,what is specification battery sansa clip 2GB with frimware 01.01.18f?
for example:

and if battery sansa wil fault,how replace it.and how open sansa.if U have pic from openned sansa.PLz give me.
Thax
Google ‘take apart sansa clip’.
hi, I know battery voltage 3.7 v.(anything about ipod-disassemble sansa topic).but i dont know mah?
As far as i know it’s an 330mAh battery.
My 2GB Sansa Clip doesn’t hold a charge long, discharges quickly with use, and takes FOREVER to charge, even if it’s only 1/8 low. I returned my first one for the same problem; nothing different with this 2nd one. Will try returning it to another store in a nearby city to see if I can get one from another shipment. HAS ANYONE FOUND A 2GB SANSA CLIP THAT HOLDS ITS CHARGE?

Test Details:
The album was played endlessly on repeat until the battery ran out of juice and the player died (battery low). Test Results in Hours Minutes Seconds HH:MM:SS. Seconds were ignored, not significant. In any individual data sampling test there is uncertainty. Don’t be surprised at the variation. You can’t calculate to the minute exactly how long your battery will last.
Observation on battery power percentage measurement:
Power percentages through windows property and through the Clips menu vary. I’ve seen the clip at 0% but windows reports it at 11%. Use the Power% like a gas gauge. It isn’t perfectly linear and sometimes it seem to stick. Turning the Clip off and on can sometimes display a different Power%.
The Power% measures in increments. 0,7,14,21,28,35,42,50,57,65,71,78,85,92,100
Volume Control Settings used for this test:
Clips volume control appears to have approximately 40 clicks from zero volume to Max volume
0 clicks = zero Vol, 10 clicks = 1/4 Vol, 20 clicks = 1/2 Vol, 30 clicks = 3/4 Vol
==========
I don’t experience any issues with battery leakage, other than once in awhile I may leave it playing when I am wearing it, or after I unplug it from the power. The clips battery lasts an amazing long time. I stick with higher bit rate VBR MP3’s encoded with Lame’s codec. v0 or v2 settings and get around 15 hours of use ( I have never ran out of juice , as I usually plug it back in after a long day).
I may repeat a few tests in 6 months to see if the battery degrades over time. They say at 500 charges you will still get 80% battery capacity, so with normal use I expect the clip lasts a decent time. At least long enough for the next cheap mp3 player to be released with more memory.

Wow–great, comprehensive benchmarks!
(And amazing to see the Clips lasting 15-17+ hours for well-encoded MP3 files!)
>> Silver wins lasting an hour longer than the Black 8GR2 *
I don’t understand why??? I’m going to retest again<<
I think the problem is that there is a quality control issue in the manufacturing of the batteries. You could compare several Clips of the same capacities and colors, and still get wildly different results between them. i.e. there are some 2GB red Clips that play 11 hours…and some that will play for 15 hours…and some that lose charge when not even playing.
The batteries are the weak links in the Clips. You just happen to be seeing the difference between two Clips of different capacities and different colors…but you’d still likely experience those differences even if you were testing two identical Clips. They all have the same battery…and it’s just the luck of the draw as to whether any Clip has a good, mediocre or bad battery.

Yes, I agree there is battery capacity variations. They are probably all within an acceptable power range.
What I don’t understand about the tests is, the Rev 2 black clip was consistantly averaging longer play times for both ogg and mp3 formatted files. I did many and the variance was consistant with these two formats. But on the Flac encoded files, it was reversed and an unexpected result. This makes me suspect that the firmware on the Rev 1 clips are clocked at a slower rate for Flac encoding than the Rev 2 clips. It’s just suspect, I hope someone at sansa notices this, and checks.
