Hi folks, Just wondering if anyone can give me some sort of idea as to how 4G will effect my battery life? EE rang me tonight and have basically allowed me to upgrade to 4G without extending contract and for the same monthly cost. Would have been a fool to turn it down. I'm just wondering what the effect on battery life is likely to be? I average around 5 hrs over 3G atm but the signal is pretty poor at work. Apparently 4G coverage in that area is decent though.
