i was wondering if i switched wireless and bluetooth on, if it will drain more rapidly out of my battery and by how much more?
-
It will drain your battery faster. I dont know how faster but it will. I have wireless on 24/7 but im plugged in a lot. I would give a guess and say that it will cut it down 20min.
-
so what would be the difference between WIRELESS ONLY and WIRELESS + BLUETOOTH
-
No exact number, but it will drain battery, depends on the activity, device, etc.
-
You said on. If it's just on, you're talking about a marginal battery drain. If on and active, it's quite significant. I'd estimate you burn battery 25-35% faster with active wireless connections.
-
Receiving a signal uses very little power. The battery load goes way up when you transmit.
-
I loose an extra 30-45mins when I enable bluetooth on my notebook.

I dont want to brag but with my 8600 on wireless constantly i get about 5 hours of battery. I love centrino! But again, it just all depends how fast it will.
-
I guess is also comes down to what your current config is and how big the batter is, but a general 30-45mins is a good average.

The atheros WIFI card really cuts down on battery usage, and also the fact that im using 802.11a 108mbps also cuts way down since the transmit power is only 40mW instead of 100mW which is common on 802.11g. The problem with 802.11a though is the decresed range, as long as you have a good router and wifi card there should be no problems. My Dlink router handles it fine though I get 90-100% signal anywhere in my house also i like the idea of using the 5gighz range instead of 2.4gighz much less interference since many devices like cordless phones use the 2.4gighz frequency.

I don't have bluetooth in my laptop (yet
), but my cellular phone has bluetooth. When I use it, the battery life on the phone drops dramatically.
Try to disable it whenever you are not using it.
