Sansа Clip Zip - Improve battery life
oid_maps:
I want to re-ask: Which "stress-tests" should I do to test if the delay values for fuzev2 work reliably? Or is it enough if without playing anything I see no flickering when switching to "hold"-position? (Anyway, flickerings could be that short that they wouldn't be visible with the human eye -- should there be some log data written out one could analyse afterwards?)

I am not sure if this is something relevant, but I tested the clipv2 build and experienced a short delay when navigating from WPS to file browser and then to the parent directory with a button press to the left. Music is playing and not paused. This doesn't happen with the current dev build.

saratoga:
The CPU speed is definitely much lower during normal use, on the other hand we used to run on even slower devices so I'm surprised a simple GUI like on the clip lags.
johnb:
I tested three fuze v2 builds that Oid Maps had provided me (will all saving patches active I believe and varying delays).
I have two devices, these are the results:
19_5: works with both
19_4: works with both
19_3: works fine with one. With the second the display shines through for a short time (flickers) when keys are pressed and a few secs afterwards.
I will now move on and test the builds that saratoga provided both on my fuzes and clip+es.
