Hello everyone! My iPad 2 seems to give me 6 hours of battery life with all background apps off, Ping off, and very few notification services. However, my brightness is on its maximum. I read somewhere people get 10 hours on maximum brightness and browsing safari but I'm only getting 6 hours or 3.5 minutes for every 1% depleted. Is this normal? Also, my wifi keeps going from full to half even when close to wireless hub anywhere I go...what's the cause of this? Thanks so much!
