lol. as the screen is activated even when skipping a song: very realistic scenario ;D
So what about the real runtime of plus vs zip?!
My Clip Zip meets the Sandisk spec, if not surpases it, for battery run time *with no memory card used*. I must emphasize that.
With no memory card, I did a test of using a 128kb mp3 file playing in loop mode. I got over 17 hrs. of playing time; during the test I had my earphones plugged in and at moderate volume. Not shabby for such a tiny mp3 player.
When I plug in my Sandisk 32GB memory card, the play time for the same file (the file is in main memory, not the expansion card) goes down to 15 hrs. I also found that when there is no memory card in the Zip, power usage is practically nil. When I have the card plugged in, it drains the battery around 1%/day approxmiately. I tried this test with mine and my wife’s Zip and with different 32G cards (all Sandisk, class 4 SDHC). Apparently the player is polling if the card is in the slot when off and it uses battery; why it makes battery life go down when the player is running is beyond me but I had 2 players in my household do the same thing so it’s not a bum player.
My solution to the stand-by issue is to just remove the card from the slot when the player is off and won’t be used for several days and also to run Rockbox. The main reason to run Rockbox if you do what I do is you won’t have to rebuild the database each time when you re-insert the card then power up the player. Using stock firmware will force a database refresh each time, that could take over 10 min. if you have a full external card. That pretty much solved it for me plus I prefer Rockbox over the stock firmware. It took a bit of getting used to but after getting over the learning curve I prefer it.
