Hello. I'm looking into writing an application to send the accelerometer information over a bluetooth connection, to feed the information from the n900 into my laptop. Now the problem I'm faced with is when i read the information from the accelerometer i'll have to update is every so often i.e. read it every 100ms, then after every 100ms send the information over bluetooth. Now constantly updating information every so often, would that start to drain the battery quickly?

Also at the same time I'm thinking even if it would start to drain the battery to begin with, as using timers only use processor tick's, so my code will only execute when the processing ticks rollover.
