Sony NWZ-A10: Battery indicator / adjust Battery
Viper73:
Here is my battery benchmark from full loaded to absolutely empty.
Please rename the "battery_bench.pdf" to "battery_bench.zip" so you can unpack it (zip are not working to upload here, and the txt was too big)
In the beginning it runs very long with an battery level of 60-100%
When the battery reaches about 45% you can see that it drops to zero very very fast.
Would be great it you can can calibrate the battery level so it has an constant battery % level.
If you need any more information please let me know.
saratoga:
I committed that calibration in 56803c8. Please update to the current build and double check that the battery meter is more accurate now.
----
Using grep it looks like the curve in there was from the YPR, which has a strange battery calibration. MIght be better to just set the calibration of new devices to always read 100% until a real curve is available. More obvious that it is a placeholder value.
Viper73:
Oh, this was fast, thank you.
I installed the new update and will let you know if the battery meter is more accurate now.
Another question, this player has no really "power off" button (which is a really bad thing). But the manual says that the player will shut down automatically from standby after a few minutes. But this ist far too long i think, after 20 minutes the player is still in standby and eats my battery. Is it possible to change this time for the automatic (complete) shutdown from standby to maybe 10 minutes? Or is this what the kernel manages and is not possible to change?
saratoga:
Yes the idle poweroff setting in the menu can be set to a shorter value, however I think the default is only 1 or 2 minutes. If it doesn't shut down after 20 minutes, my question would be if it ever shuts down?
Viper73:
Do you mean the "on/off" settings in rockbox settings? This settings are working, after this time (5 minutes for example) the player shuts down to the "select player" menu. When the player is set to "hold" the player is going to the standby mode after 5 seconds. (If the player is not in "hold" mode the player restarts after 10 seconds to rockbox).
But the player does not power off completely. Even not afer one night in standby. Maybe sometime later, but this is far too long.
I want to set the time when the player is in the "select player" menu. Here i want to set the time to 5 minutes (or less) for the complete power-off (so the player is completely off and needs to reload the bibliothek when i restart the player). Can this be changed, too?
