Drained battery with iPhone 3G 3.0 upgrade

Question

I loaded the new 3.0 software a few days ago with no problems. Today I found that my "turned off/ idle" phone in my pocket had gone to the new Apple recorder program and has been recording for 58 minutes by the time I discovered it. So unknown if this will be a source of battery drain by a program starting on its own (buggy?).

Answer 1

mine lasts a lot.
this is pretty much the daily use of my iPhone3G using 3.0 for a week.
i work from 7am to 4PM, one hour break time in that timeline , its on standby for 8 hours , on break time i pretty much make heavy use of Youtube , Safari and Mail among other Apps like IM+ and sometimes some games, after my work day i still have almost 50% of battery left.
my settings
Push is set to manual
Notifications are On and have 4 apps on it
the internet connection is always 3G
so my guess is that you guys do heavy use of your phones all day or maybe you guys are leaving the Safari , Mail and IPod apps running in the background.
test this and see if your battery lasts longer.
after every use of Safari , Mail or IPod before putting your Phone into standby do this, open safari, then press and hold the top button until you see the slide to power off option, release that button and now hold down home button (square) , after 6 seconds it will return to the home screen and Safari will be closed now ,do the same for Mail and IPod, open mail press top button until off slide , hold home for 6 seconds , then open Mail , hold top button until off slide then home for 6 seconds, now apps that don't shutdown like Safari , Mail and IPod will shutdown and the phone will use less battery while on standby. if you open them again they will again remain open and drain battery.
there was a function on 3.0 when it got announced that it would close every app to save battery, people complained about it, apple listened and removed that function. now only Safari ,Mail and IPod apps stay processing and wasting battery in the background.
