Camera Killing Battery Life?
I got my phone Monday and have been using it for around two days. In both instances, the camera was the process that consumed the most battery, according the battery usage information in the settings. Today, camera used 32% of the battery, while android sytem used 25% and Sprint Naviagation used 12%.
Why did the camera suck up so much juice, despite taking around 15 photographs?

I'll add to this
This was from 9 hours of usage. I only used the camcorder for 32 seconds. Does this look right?
I also spent time on youtube, web browsing with wifi, and browsed the market a lot. It doesnt make sense that the system is only at 9% and camera is 82% considering I used it for such a small amount of time.
Sorry for the bad quality pic, I hope you can make it out.
Thanks for the help!

To put it in perspective: The EVO has a 1500mAh capacity battery. An average LED uses ~20mA to light, but since these are bright-*** LEDs, lets call it 50mA. The flash fires for ~2 seconds. 2/3600 = .000555 hours * 50mA = 0.028mAh * 2 flashes = 0.055mAh of usage for both flashes during a photograph. This amounts to 0.0037% of the total battery capacity of the EVO.

Use some task killer application especially something like Advance Task Killer, on the other hand you may also try the Low Battery Camera -> https://market.android.com/details?i...wbatterycamera
