    With similar code I know the battery indicator does not work way back in DX50. But I only started to look at the battery indicator in DX90 since the latest build. I saw it go all the way down to 0% and shutdown after a couple of minutes after that.
    The latest build actually prevents DX90 from going to sleep state (which I found is contributing to the crackling noise that appears randomly). it only turns off the backlight when idle time is triggered. I believe that may have influence on how the battery indicator work on DX90.
    EDIT: Just got mine below 90% and still counting down.

    The settings don't revert every time but about 30% of the time I start the DX90.
    The delay also happens with the simple bass and treble settings.

    Thanks for the effort headwhacker. I haven't tested the battery indicator yet, but the settings haven't reverted to default a single time since I installed the new build. :)
    There are two new problems though.
    1) I can confirm that, if you change the sound settings (e.g. bass, treble, balance, etc.), the changes only take effect after skipping to the next track.
    2) When you play a song and fast forward to the end of the song (e.g. 30 secs before it ends) the album art disappears after a while and only comes back after skipping to the next song. This doesn't happen when listening to the last song of the playlist though. It is not a theme related issue.
    Thanks again for all the hard work. Rockbox keeps getting better and better. :)

    I just tested mine with the latest build. It was still 98% before the battery died...

    ok thanks for testing. Reading the /sys/class/power_supply/battery/capacity for the battery level seems to be inconsistent.
    I'm trying out a solution by reading the voltage instead. I'm just waiting till my DX90's battery is drained and see it gives a better indicator.

    Appreciate all the work so far!  Just a heads up -- the settings still reset on my DX90 as well.

    Voltage should work great.once you find your reference low V.[​IMG]
  8. headwhacker
    Actually better, I found both low and high :)

    New build ready for download.

    Starting from 0.1.7 build i spotted some weird behavior of touchscreen: when it's not on hold and turns off it still is processing touches. As I walk with it in my pocket it was quite a surprise (i don't usualy use hold, because it's preventing from track seeking: just skips a minimal interval ignoring how long you hold next/prev)
  12. headwhacker

    It's normal starting at build 0_1_7. It only turns off the backlight but prevents the system (including the touchscreen) from going to sleep. Switching between sleep and awake states contribute to the audible noise (crackling noise) that can be heard on older builds while rockbox is filling or refilling audio and pcm buffers.

    You will have to use the hold button more often now to deactivate the touchscreen :)

    That's a bummer, but nothin i couldn't live with. At least, now i know that seeking on hold was fixed somewhere along the way :D
    Btw, is it possible to make hold button toggle screen backlight (among inducing hold state)? Would reeeeeealy apreciate that :)

    Flashed newest firmware and did a factory reset but still can't get DB to fully build in Rockbox even though it does fully build in Mango. Any idea how to fix this?
  15. headwhacker

    1. Make sure Rockbox only scans your SDCard (/mnt/external_sd)

    2. In settings, the option "Gather Runtime Data" is set to "NO"

    Both of them are in Settings -> General Settings -> Database.

    If it's still not building, clear the contents of the rockbox folder in the DX90's internal storage.

    If all else failed, there there is a file/s rockbox is unable to read in your SDCard.
