Poor wifi and battery life
I use a wifi router at home to access Internet, and it actually have to pass through two thick walls to reach my room. I usually get a signal which is 75 to 90 dbm which I believe is not great. My question is does this affect my battery backup? I feel like like when I use wifi my battery is getting grained rapidly. Its worst when I use playbook. If that is an issue, I am thinking of a wifi extender. Any thoughts ?
Note: mine is iPad 2 wifi only with latest OS.
