I've mentioned in another forum (here at MyMpx) that I recently got an MP5 player while in China. It's actually pretty nice and works fairly well. A couple of things I thought I'd throw out here:
Battery:
My player lasts only ~2 hours on a single charge. The battery claims (this is China, remember) to be 520ma hrs. which means this puppy would be drawing ~225ma when it's playing. That's a lot given the circuitry and devices used in the design. When I've checked the specs for how long MP players last on a single charge, I've typically seen 10-15 hours. Is this consistent with what most people find?
Unfortunately, when I plug it into a USB port (I run the audio thru some computer speakers while I'm working), it either comes up ready to transfer files or it goes into charge mode, so I have to wait for the player to charge before I can use it again. Again, is this typical? I may look into modifying the power supply/battery connections assembly one day to change this.
Clock/Calendar:
This is prob'ly one of the downsides of this player. It has a "calendar function", but there seems to be no way to set a clock...which means the calendar always reverts back to 1/1/2001 (apparently old firmware
and serves as nothing ore than a reference function for days of the week
The upside is that it does have a stop watch function (that will allow me to time how long it really takes for the battery to die....
Here are the basics of my unit.
CPU: Rockchips RK2705/6 (I think now it's most likely an '06...just lousy printing)
Flash Memory: Samsung K9GAG08U0M 16Gbx1 (2GBx8) NAND flash memory device
"Working memory": 8x16SDRAM (That's all it says
FM Stereo: SP3767 (I think this is similar to the STMicro 5767(?)
Anybody have any experience with this design that they might be willing to share.
Thanks and cheers...Steph
