Hey all,
I've recently noticed that my iPhone 4 actually gets better battery life on 3G than on Wi-Fi, which contradicts everything I've read on the matter. On Wi-Fi, I get 4-5 hours of life, compared to 5-6 hours on 3G. I've restored my phone several times in the past and I've always had this level of battery life when using the Wi-Fi at my house, so I just assumed that was how it was. I can still easily get through the day without charging, so I'm not too concerned. I am curious though, and I certainly wouldn't mind extending the battery life and lifespan.
Using the settings Apple used in their battery tests, except on minimum screen brightness while surfing the web with Safari over Wi-Fi, I get around 6 hours of life, not the advertised 10 hours.
I have my Linksys router set to 802.11g only, using WPA2 AES security. (Maybe this has something to do with it?) I have an excellent Wi-Fi signal (router in the next room), and an excellent 3G signal (5 bars, -75 to -60 dBm) the majority of the time.
Regards,
Mike
