K, so this is my second Android phone, and the Aria I had before it I only had for two weeks. When I had the Aria I had read that if WiFi is turning itself on and off every time you lock/unlock your phone it hurts your battery life. This made sense to me cause in my experiences 3G wastes battery faster than being on WiFi, and I would think having to reconnect to the WiFi connection every time I unlock the phone is an unneeded process that I could do without as well. I checked the WiFi sleep mode setting on my Aria after I had read this, and it was already set to not go to sleep when the phone is locked.
Now, with my Captivate I've been trying to tweak it best as possible to get the most battery life out of it without killing off any major features and without using those task killer programs or anything else wasting system process just to free up some. I just remembered today to check this setting on my Captivate and to my surprise the default was set to "When screen turns off" WiFi goes to sleep. At work and home (2 places I am at 80% of my time) I am always in range of WiFi... why not make use of it?
For those that want to change this setting and are new to Android and haven't found it on your own here is how to get to it:
Settings > Wireless and network > Wi-Fi settings > hit your Menu softkey > hit the Advanced button that pops up > Wi-Fi sleep policy
From there you get 3 settings, I have set mine to Never.
I will be looking forward to see if I really do get any significantly better battery life.
