Date: Mon, 22 Dec 2008 16:06:11 +0100 I did some battery benchs, as kugel and some devs said they could help..... i did all with my sansa e280, r19396 and the default settings. 1. mp3 VBR ~192kbps, showing wps of cabbie v2: *22:28*, but its not important. 2. .ogg VBR ~256kbps, cabbiev2, showing the main menu: *19:51* 3. .ogg VBR ~256kbps, cabbiev2, showing the wps: *18:03* 4. .ogg VBR ~256kbps, showing the wps of FreeState (a complex wps). i added randomly 4 peakmeter tags to the .wps-file, in the wps 2 peakmeters were shown: *16:51* 5. .ogg VBR ~256kbps, showing an empty wps: *19:53* 6 .ogg VBR ~256kbps, showing the crippled FreeState-wps from 4., but with http://www.rockbox.org/tracker/task/8523: *18:05*. in short: runtime with a menu shown: 20h, with the cabbiev2-wps: 18h, with a complex wps: 17h, the same wps with the patch: 18h, with a empty wps: again 20h as the menu. you see that showing a wps even when the backlight is off need power. a "quick and dirty"-fix could be switching to a menu when the backlight is off, switching back when its on again. but its not the prettiest solution :) i hope this helps you a bit in improving the runtime of the players. if the devs [and of course kugel ;)] think some more benchs with other themes, patches etc. could be helpful, feel free to mail me Received on 2008-12-22 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
