I have the same iPod and i made the same mod u wanna do, with the only difference i used 2x200gb (cause I used them for the xDuoo x3). Everything works damn fine. Trust me, it worth it! :)

  Hi, where did you bought the batter with the back cover? Could you please give me a link to a seller that sends worldwide? I'm italian.   I tried on super-ipod.com but after a week the product is still on "Processing" status... Then I tried on ebay, at the seller canamyfly2013, I asked a...

I'll try that!   Yes, I knew that. I personally opened the dap and seen its capacity (2000mAh). But I'm here not to complain that, I'm here to understand why, on rockbox, when I skip a lot of songs, the battery drain is worse than the stock FW.

Ah that makes sense now.     Well I don't know how to bench it properly, I mean I could leave it playing but I won't now exactly how much time will it take to fully discharge, but I think will be almost the same as rockbox.

Guys here's my bench, with nearly 12h on continous playing. So the problem exist only when you start to skip a lot, damn.

http://pastebin.com/wvF9qtci   Guys here's my battery bench... Dang, it reachs nearly 12h on continuos playing, so the problem there is only when you start skipping songs, damn.   The only thing that I don't understand is why "Left time" shows always -1.

The only thing I hate about original FW is the update of the library bug. As I said, when I do the update of the lib, it suddenly stops, not including all my songs in "All Songs" and that's a problem for me, cause I shuffle a lot. If anyone could help, I'd be very grateful!

Well I'm going to post the bench when it'll be ready, so maybe, who wants, can work on it. I'll try to find a solution too, maybe recompiling and reconfiguring from the source, but I repeat, I'm not a programmer at all, I'm just a guy who wants a nice rockbox port with decent battery life...

The AK would be my dream ahahah! Yes, a good sound as long as you have a good pair of headphones. I have a pair of cheap xiaomi that sounds almost good but started wanting something more. I ordered a pair of Piston3 but they have to arrive yet. Any advice on a good pair of cheap in-ear or...

Quote: Yeah, just some people here had the battery drain issue and I don't know why at all. Maybe because people listen to their songs in different ways, i.e. I skip a lot of songs and this drains the battery very fast. I have my x3 since two weeks, I can't choose another one too much...

Yeah, for sure it'll be a software problem, in fact I sent a pm to XVortex telling him that I'll provide him a battery bench to fix the problem but still no response... Plus I found on the net how to modify some source file to have a more accurate battery calibration, but I'm not good ad all in...

Uhm I use almost mp3 320kbps files and just some m4a in facts.

I think so.     The only time I had the same error was everytime I tried to did things (starting playing music, browsing into foders or settings) before the processor icon was completely gone. So I think you have to leave it for some second, the time that the icon go away, and then you can...

I think the lag in the navigation exist because you have a lot of songs maybe? 'Cause it happens sometimes to me too (I have about 23k songs), but nothing tragic, I have just to wait some more seconds, then it goes. Maybe it takes more time beacause it has to build the dynamic playlist? Anyway...

Yeah, on continuos skipping, the battery drains very fast. Maybe a battery bench from rockbox could help?
