I find that I need to carry my charger cord during a long busy day of phone use including emailing, app use, internet and music listening. The battery will last longer of you charge it nearer to the lowest %.
Me too. I bought a spare cord just to have with me on the run as I don't drive. Even just texting etc on the train can reduce the battery down to 70% and that's before I even get to listen to music while doing my junk mail round.
I do long (sometimes country based) walks with a friend once a week and a disadvantage of that is nowhere to charge the phone all day. (we don't drive so can't use a car charger) By the time I get home from those at 6-7 pm, the battery can be below 30%.
At least once a day. My iphone sometimes gets charged more than once a day, especially if I've been using it to play music. I have a docking station which doubles as a charger so as well as charging every night, it gets an hour or so on the docking station most days too.
I put my phone to charge over night every night. I find the batterie don't last a day only if I use internet a lot or play too many games on my phone! If I am mindful about these two activities my phone battery life is pretty good. I have a htc
