GPS Battery Benchmark

[gbm85]

I know some Kaiser users have tested the effect of GPS on the battery, but I haven't seen any Titan users do it, so I figured I'd give it a whack myself. If this has already been posted somewhere, I apologize.

I used acbPowerMeter 1.1 in this test. All today plugins were disabled. Backlight was set to the lowest level. Backlight always on, automatic power-off disabled. I soft-reset right before the test. For the GPS test, I opened TGPS, waited for a fix, then switched back to acbPowerMeter and reset the graph. The results:

Two minutes at idle:
52 mA minimum, 136 mA max, 80 mA average. 2 mAh used in 2 minutes.

Two minutes with TGPS in background:
198 mA minimum, 252 mA max, 205 mA average. 7 mAh used in 2 minutes.

So that should give you some idea of the impact on the battery with GPS active.
