vr12 Posted June 12, 2004 Share Posted June 12, 2004 Just recieved 60CS, measured current draw. Here is what I got, running time calculated for 2100 mAh cells: 1. Compass is off/Demo mode - 40 miliamps or 52 hours 2. Compass is off - 76 miliamps or 27 hours 3. Compass is on - 117 miliamps or 18 hours 4. Compass is off/light 50% - 163 miliamps or 13 hours 5. Compass is off/light 100% - 200 miliamps or 10 hours Quote Link to comment
+Tahoe Skier5000 Posted June 13, 2004 Share Posted June 13, 2004 (edited) And I thought I had way too much time on my hands. Anyway, nice job getting the data. I'm sure it will come handy some time around here. Those numbers seem a bit lower than I thought... I'm guessing the Garmin specs were a bit lofty and probably with battery saver on, with no backlight at all. Edited June 13, 2004 by vw_ev Quote Link to comment
+Centex Trekker Posted June 13, 2004 Share Posted June 13, 2004 What is it when compass on/light on? Quote Link to comment
+Geo Leo Posted June 13, 2004 Share Posted June 13, 2004 (edited) Not bad. Keep in mind that even with the compass on, it will only stay on when you are not moving. It is unlikely that you would want to leave it on continously when not moving, so actual performance with the compass on should be higher if you were moving part of the time. Same with the light. It is unlikely that anyone would leave the light on continuously for that long. My experience with 2200 mah batteries with the light/compass on intermittently (normal use) has been excellent, at least twice as long as with my Legend. Probably around 20-25 hrs.

vr12 Posted June 13, 2004 Author Share Posted June 13, 2004 What is it when compass on/light on? It is when compass and backlight are both turned on. Quote Link to comment

I'm guessing the Garmin specs were a bit lofty and probably with battery saver on, with no backlight at all. Running time I calculated is for 2100 mAh NiMH, running time will be consistent with Garmins data if you take Alcaline cells which have capacity around 2700 mAh. Quote Link to comment
+jotne Posted June 13, 2004 Share Posted June 13, 2004 What is it when compass on/light on? It is when compass and backlight are both turned on. Just some math. Power drain divided down to each unit. CPU 40mA GPS 36mA Compass 41mA 50% Light 87mA 100% Light 124mA So Compass On +Light on 100% CPU+GPS+Compass+100%light 40+36+41+124=241mA and if you use the measured time for the battery life, this would get around d 8 hours.

vr12 Posted June 13, 2004 Author Share Posted June 13, 2004 I tried to measure current for "battery saver" mode But readings jumping between ~40 and ~80 miliamps (compass is OFF) very hard to average it. Looks like in saver mode it turning GPS off pereodically. Quote Link to comment
vr12 Posted June 1, 2005 Author Share Posted June 1, 2005 Just want to add: I measured current in battery saver mode 1. Normal mode 79 ma 2. battery saver 60 ma 3. Demo mode 40 ma also measured current during screen activity moving/zooming in and out - 85 ma. that means on 2500mah NiMN one can have 38 hours in battery saver mode (no backlight&compass) Quote Link to comment
+CompuCash Posted June 2, 2005 Share Posted June 2, 2005 What is it when compass on/light on? It is when compass and backlight are both turned on. cute - beat me to it !! Quote Link to comment
