I've got the 4G, I'm with Three, so they don't use 4G at mo, mine lasts roughly 2days normal use, or like you I've just come from an Active 2 and battery seems the same, but supposed to be better, I've heard tho that 4G gives it a belting battery wise, think I'll just keep using the Bluetooth etc, even when 4G available and keep my battery, always got my phone on me anyway. B4 anyone mentions why buy the 4G version, it was because they gave me £150 trade in from Active 2 against the 4G, but wouldn't give me anything if I bought the standard Bluetooth... strange I know 😕
