I would > personally cap at maybe 89%, 90% or maybe 95%. Would it be possible to use a different voltage curve during charge? At least for the player, the voltage is typically a bit higher when the charger is plugged (e.g., with full batteries the voltage is 0.10 to 0.15 volts higher when the charger is plugged). > Charger plugged icon: This will not be shown when the charger is not > plugged in.

Something similar could be created using custom chars (each being 5x8 pixels), but I guess text, like this, would be better: "Batt: hh:mm" (btw, my player is patched to show percentage instead of "Batt", but that's not very informative for the average user). -- Magnus HolmgrenReceived on 2003-06-14 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
