All the more reason to want greater internal storage capacity...

 

C'mon, Sansa, listen to your market! 


This may be a stupid question....but would a 16GB card require more battery power to access than the 8GB card I have now, if I was to upgrade?

It doesn't matter if it is 1, 2, 4 or 16 Gb or SanDisk, Kingston - all of them shorten battery charge even if you don't play the files on those cards. I guess it is the price we have to pay for the seamless integration of those cards in the player. Most likely it is the reason why Creative Zen is that staunch against the card integration in their devices.

Although not everyone has seen the battery drain issue with cards inserted, I have.
Glad to know I'm not alone.

Re: Sansa Fuze Firmware Update

@Reviewboy - Not scientific by any means, but my new Fuze w/o an sd card (yet) seems to have less battery drain than my previous one, which I had an sd card in from day one.

 

@Marvin_Martian - I'd also like to know more specifically about this. Is the so-called/alleged "drain" a static thing due to the presence of the sd card or is it a dynamic function related to level of data usage from the card (e.g. the player has to pull data from the card to the internal memory to 'play' it, resulting in more power usage than data from the internal memory). Clearly if it's the latter then a larger card holding a larger percentage of total data would result in increased battery usage.

Re: Sansa Fuze Firmware Update

 Robisan, IMHO the size doesn't matter in this particular case... I feel the drain  with 1Gb, 2Gb, 4Gb and 16Gb SanDisk cards.  

As I mentioned earlier I think that the drain happens due to the integration of a card in the player.

If I am right -  wouldn't it be reasonable to introduce in a future firmware (if any) a kind of function switching off seamless integration in MSC mode while using only FOLDER browsing to access the files? In case of folder browsing the seamless integration is not needed at all. It might improve the battery life.

 

For comparison I had a look at my 2-3 year old unbranded Chinese Rockchip-based  mp3 player with an external card (it uses only folder browsing - which is very fine for me) and I can't see any difference in the battery life - no matter if has a card inserted or not.

Re: Sansa Fuze Firmware Update

Adding a memory card to the player is exactly the same as adding a memory card to a computer. You are adding extra electronics that require additional power to operate (whether or not you access access or use it). Memory chips are not designed in a way that allows their data and address lines to remain connected to hot circuitry with their power lines not connected (or turned off). Doing so could damage both sides of the electronics.

 

As such, anytime you put a memory card into the player it will always drain more power from the battery than without the card.

 

Beyond that, the amount of power needed to actually access the memory (to play music from it) is very, very little. It's unlikely that you'd even be able to notice a difference in run time just based on playing all from the internal or all from the external card memory.

 

It's really only the fact that the card requires power all the time (regardless if you access it or not) that drains the battery more.

Re: Sansa Fuze Firmware Update

Interesting discussion. Anyone out there who has some numbers on battery life with and without external memory card (e.g. playing mp3 only)?

Perfect! You are the one I'm looking for because I don't own a card. Smiley Very Happy

 

I get 25hrs of mp3 playback (96kbps, volume level 75% on "Normal" scale, backlight 50% for a total of about 20min). I'm curious to see your numbers soon ...

Thing is, I have lots of different file types, and bitrates....so I don't know how scientific a comparison would be. I do have a few WMA VBR and Ogg Vorbis files that are close to your bitrate there, but those codecs use more battery power to decode than MP3. The vast majority of my files are much higher bitrate...my 4GB +8GB card has 2,224 songs on it. I'll try to remember to keep track of the time the next time I use the Fuze, but it'll take a few days to get through it. You might have to remind me though. Smiley Tongue

Only a suggestion: pick a single mp3 file and let the fuze play it back repeatedly over night or some other time you are not using it - if there is any. Smiley Wink
