bob, in general terms you will always save battery power when apps or
functions requiring power are turned off. that being said i have somewhere
north of 125 apps on my iPhone 4 and none of them are "off". most of them
have a notification function that is also on. i leave my bluetooth
function turned on and just turn off the headset itself. i don't make a lot
of calls and i do some texting. i primarily use my iPhone as a 'radio'. i
listen to music, podcasts, internet radio and traditional AM/FM stations
that have an internet presence. those types of things easily make up 75% of
my daily iPhone use. with rare exceptions i find that my battery easily
lasts all day. by the time i put it in the charger at bedtime it usually
has from 25-33% of it's charge left.
good luck
rich

iPhone 4S. I have not used a Bluetooth device and have a couple of
questions if I might. I use my Bluetooth headset almost exclusively for
listening to audiobooks, no music, few if any phone calls. I understand
that using a Bluetooth device will radically shorten a battery charge. To
conserve battery time should I completely turn off the Bluetooth option in
the phone or is it good enough just not to be using the headset, although it
is still turned, even though it was still connected via the Bluetooth?
Thanks in advance, Bob
