Yesterday I updated my Twitter status to say that I’m starting to like my new iphone, but I can’t believe quite how poor the battery life is.Maybe this has coincided with starting to cycle the first few miles to work before boarding the tube, I don’t know. When i started thinking that my laptop only runs for 2-3 hours and the iPhone in regular use only runs for 6 hours, I realised how basic battery technology must be. The Twitter responses were to turn off wifi and push email, lower the screen brightness – but guys (followers?), doesn’t this defeat the whole object of owning an iPhone? Of course, I’m not suggesting that I could ride my bike for 2 hours anyway!
