    Just been running some tests and today i have killed all apps after using them...

    ALL DAY ON 3G NO WIFI

    unplugged 10AM

    used irregelarly and not very frequently. prob couple of sms and checked twitter and facebook 3-4 times...

    check battery again about 5pm and only used 5%

    used same amounts again, checked now uk 8PM and on 90%

    normally im on about 80% so i guess this is down to me killing all background tasks after use. which makes sense. now to kerb my OCD behaviour im looking to disable multi tasking to gain this batt life and tbh i dont really need it

    im not jailbroken and running 4.1 on iPhone 4

    Many Thanks

    no and the apps "running" dont drain battery, your test is about as scientific as the mythbusters doing it. In other words your test is not scientific... you in no way proved anything because your phone may have been used a little more than the prevous test without you even thinking about it.

    This is not a valid test: battery discharge isn't linear. Also, if you move around the baseband will interfere with celltowers. Different celltowers ask for different power consumption.

    Answer to question in thread title: No.

    Advice: just don't use any apps or manually kill them (I know I can't be bothered with it: I pay the electric bill).

    Apple Multitasking doesn't run background task, the moment you exit the app, it is frozen in that state. All it does it just remember exactly were you left off in a game/app, but the app is not active in the background so it does not use up battery life.

    If you really want to preserve battery life, Turn off:
    Wifi
    3G
    Cellular Data
    Location Services
    Push Email
    Notifications
    Vibrate

    Lower the brightness
    Don't record movies (720p useless a lot of battery)

    theres no need to get sensitive and i only ran the test as i wanted to see a difference and ive noticed a 10% difference... i totally understand its not scientific nor accurate. its something ive noticed... from 11am to 7:30 i was in one district and than moved to another had wifi on but not connected as i wanted to leave everything as normal...

    im a firm believer of using devices to its max and im not complaining about the battery life just trying to maximise its potential

    this is what i thought until today where the batt life increased from killing apps, this is the only change ive made...

    Whatever everyone else says is stupid. Multitasking DOES use up my battery. And it's annoying. I could leave a few apps open, and go to sleep with 100% battery, and wake up having 82%. This never happened before iOS4.

    You have to Jailbreak it first.

    Read the posts. Several have told you you can't do it. And the guy after your post told you you have to jailbreak.

    Is there a way to disable certain apps? That would be cool.

    I repeat again and again: Apps never run in the background. All they are is frozen. Frozen. FROZEN.

    So what your saying is the apps DO run in the background and are NEVER FROZEN so your battery DIES FASTER??

    I hear now.
