CPU usage while track recording

Did you also test battery usage while trackrecording when
a) mapsforge map is sued
b) blank map is used

imho there should be no difference at all (!) when the screen is off. Yet my tests showed case a) to use a lot more cpu.

I'm using mainly vector maps in terrain so the stats reflect using of vector maps also. There was maybe issue on version before 1.15.x, but latest, should work correctly in this way. You may also try ...

locus 1.15.2.5

sorry, but imho this is still very wrong. why does the chosen map make a difference when the screen is off? are you absolutely sure that you arent calling pointless mapsforge functions when the screen is off?

blank map, track recording with screen off, cpu at 200mhz. FINE.

mapsforge, track recording with screen off, cpu all over the range. WRONG.

hmm quite interesting. Before your test, I should for sure say, that I'm sure

, anyway I'll check it again because there should not be any difference ... may you just for my curiosity, try this also with any offline map? Thanks ....

with rmap, it looks good. just like blank map.

joeloc · December 21, 2011, 21:15:26

... and now it looks good with mapsforge as well!

grmpf. maybe you should just ignore me :/

hmm, this is similar like issue that I was discuss with rijackson here viewtopic.php?f=10&t=1440 ... it's not your problem but have to be some issue in Locus. If you discover some specific issue with some settings, tell me for sure ...

could it be related to the compass maybe? and auto-rotation of map? maybe that is called when screen is off?

anyway, i cant really reproduce the problem at the moment. so better wor on something else :-).

nono, in moment you turn off screen or screen that need compass goes away, compass is also disabled. Really, in locus is very lot of features that helps keep CPU and battery usage as low as possible. Anyway in every system are mistakes, so ...
