seems to me mostly users who have
1} bluetooth enabled {disable it to off unless you use it all the time i use it once a month max}
2} wifi enabled like all the time
3} location and siri set to on i cant use siri it dosny understand the scots as for location services good idea for photos so leave it on sometimes for photos and google earth etc
4} use the icloud like all the time
if you push to it it pushes to you all the time disable it it is a backup
so upload once after a few months / weeks of use of the phone
then once every so often
it doesnt forget you if you forget it
and the other thing is email i found apple support sends heeps of junk mail to me costs 3g and wifi and therefore battery
use the power key to close the phone to standby after a call or etc session
saves it a few mins of use a day
i get ~ 6days this way
new run it to 0 past warnings {two weeks ago} added all apps i wanted couple of games and heeps of music via my laptop usb {it does charge also but i ran it down to zero after filling it up with apps music and tools etc...}
from a 0-100% recharge from wall {phone off} you get 5 days with 7hrs use
then a 20% to 100% charge {phone on } you get ~6days with ~20hrs total use
then well this is then
and with heavy use i have 1day 3hr
with 6hrs use {wifi 3g and texts phone calls{2{long more than 20mins each}}}
and 69% left to go...
what is seems to me is that for a given incoming signal the phone outputs far too much rf power
i use a plastic case
as the phones antennas are top and bottom
and there is issues knows for the iphone 4 antennas
so to avoid this i got a screen protector and case for £2 from ebay
i think the RF in doesnt effector the RF out
hence the phone uses far too much power
there is only unit power to concider here
1} rf TXRF mixers +PLL
2} 2X MPCU
3} 1X display and touch
4} wifi chipset
5} bluetooth {prob unified with wifi and 3g output mux}
so in terms of power only numbers 1,2,3 CAN use the sort of power drain thats going on
somepople say ohhh 3g bluetooth network etc is using the power
this is rubbish
as these simple ic's are physicaly incapable to draw that much current
they run on 3.3v and draw like a few miliamps at max in standby maybe uamps
so.. it must be the rf stages or mcpu or display sections
that has a software bug
most often induced by the user
