[Clip+, Clip Zip, ClipV2, FuzeV2] Improve battery life, part 2
Mihail Zenkov:
I update links to v11. v11 same as v9 but based on fresh git.
If it working without big problems - I want know which minimum CVDD2 we can set for each player. To check that you should extract sd card and play music from internal memory. Then step-by-step set lower CVDD2 in debug menu (don't change volume - it reset CVDD2). After each step switch to next track and check what you have in debug menu "SD retry stats". When you got "internal flash reinit" > 0 - check is internal memory freeze (you don't see files or can't paly it) or not (you can play next file but reinit rising as it was with sd cards).
I want know:
1. Name and variant of player.
2. On which value of CVDD2 you got reinit?
3. Is internal memory freeze on reinit or not?
4. With which value of CVDD2 you can play music for long time (> 1h) without reinit?

Just to confirm: the procedure/experiments you describe are WITHOUT SDcard, i.e. we are testing the standalone player?

yes

On a clip+ variant 0:
Installing -11, shutdown, rebooting and then playing a song I got a panic (pic 1), but this happened only once.
N.B.: sometimes the value of CVDD2 resets to 88, even if I never used the volume keys. So I checked back on the debug setting regularly.
I manage to go (step by step) down to 76. Stats stayed at 0,0,0,0. Also bookmark creation during shutdown worked. I have a long playlist running right now.
However, getting safely down to 76 is the tricky part. For instance, after the successful shutdown I had a hard time getting safely back to 76.
If you try several increments at a time, it can get stuck. Anything can happen from
not responsive at all,
WPS updating when skipping, but no playback
to crash with dc_write_callback (pic 2).
Once the stats values start to increase it almost never recovers.
What seems to work is: play song (and pause), decrease CVDD2 1 per 2sec, go back to WPS, play, skip ...
So far 75 has not worked for me.
I will report back on the playlist.

Great result! I got only 87 on first my clip zip (variant 1) and 88 for second (also variant 1) on long playing.

Should be fixed in v12. I update links.
