Sansа Clip Zip - Improve battery life

What should we change in gui boost patch to see it in mainstream?

If I understand correctly, that patches changes the current boost on scrollwheel behavior to boost on any button press and then enables it for AMSv2 targets?
I think enabling boost on scrollwheel for the fuzev2 should happen regardless, all other scroll wheel targets do it, and its probably necessary. I'm not sure about the other change to make boost happen on more types of button press, we should probably talk to other people about it. Testing on my Clip Zip playing MP3 (fast enough that there is no boosting at all) I notice that menu transitions involving album art are noticeably slower when unboosted, but otherwise everything seems comparable. I don't think boost is really necessary, but I am ok with enabling it as the cost is very low.

Yes.

Many people note low response rate with frequency scaling patch. We can boost not at all buttons, but is it have sense?

I feeling mostly same, but I don't use EQ or DB.

Yes, few minutes at boost - mostly nothing for whole playing time.

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.

To complete the information, those builds are based on the following git sources:
* delays of 19, 05 and 19, 04: Rockbox source from 2016-01-16,
* delays 19, 03: Rockbox source from 2015-12-26,
and then patched with the following patches, applied in that order:
* amsv2_scaling_v9.patch
* fix_button_clipv2_irq.patch
* fix_hold_fuzev2-2.patch (with varying delays, see above),
* rockbox-gui_boost.patch
* rockbox-restore_irq.patch
* rockbox-usb.patch
as posted in this forum,
as well as the patch
rockbox_firmware_tuner.c.diff
which is by myself and enables the maximum available frequency range
(76..108 MHz) and minimum available frequenc granularity (0.05 MHz) of
the device when the tuner setting REGION_OTHER is selected.
saratoga:
Committed frequency scaling. Do we want to do boost next? Its probably annoying to use the Fuze V2 without it.
Edit: Just realized its already enabled, but only for the scroll wheel.
