How much of a battery drain, freeze or slow down remains to be seen.

Although many people think it is best to let the battery drain completely before recharging, he said, that is not, in fact, true.

While the systems draw power from the camera, neither lens appeared to speed up battery drain significantly.

No 4inch screen (harder to work with one hand for most people, more battery drain, not "retina")?

This enables adequate power, without battery drain, to be supplied to the vehicle's equipment at the scene of a major incident.

For me, battery drain isn't the issue.

The key to that was extremely low battery drain and for them to be tremendously rugged.

However, leaving it on is a battery drain and prior to 2.2, it would stop working properly if I left home and then came back.

And you don't have to worry about battery drain!

This mod has the advantage of not adding weight to the helicopter and therefore doesn't affect battery drain.
