    My time since last full charge:

    usage: 4 hours 30 minutes
    standby: 4 hours 30 minutes

    Can someone please explain to me the differences? How could they be the same?

    I read their description online but I'm not really following... I'm dumb I know

    Usage: Amount of time iPhone has been awake and in use since the last full charge. The phone is awake when you’re on a call, using email, listening to music, browsing the web, or sending and receiving text messages, or during certain background tasks such as auto-checking email.

    Standby: Amount of time iPhone has been powered on since its last full charge, including the time the phone has been asleep.

    It most likely means that something is running on your phone in the background if both the times are equal to each other.

    useage is anytime anything is running on your phone be it a call, txt, internet, or even an account sync that may be automatic.

    Standby is when nothing is running on your phone and it's asleep. Your standby will always include your useage as part of the calculation. For instance, if your standby is 8 hours and useage is 2 hours, then 2 hours of the 8 hours of standby are "in-use". They somewhat overlap each other and are not meant to be added together.

    As posted above, it sounds like your phone has something running in the background that is causing the numbers to be equal. Is your phone hot? It may be if it has been doing something for the past 4.5 hrs straight. And your battery will be close to dead.

    As I type this, my useage shows 1h 12min and standby shows 4h 9min and I'm at 91% battery. This means that my phone was unplugged from the charger at 100% charge 4 hours and 9minutes ago and that 1 hour and 12minutes of that the phone has been "in-use" (I was listening to music). I hope this helps. You'll likely need to do some more research as to why your phone is constantly in use. It shouldn't be.

    Hmmmmm I wonder why my phones always in use then. I am playing words with friends, texting, facebook messenger... but those aren't ALWAYS running i dont think.

    Right now it's at 68%
    5 hours 1 minute usage
    5 hours 1 minute standby

    Not really sure what could be causing this haha but my battery definitely is not doing TOO poorly given the situation

    To Find Out

    Double tap the home button and look for any open apps. These can be closed by holding the icon until the minus symbol appears, you can close all that are running that way.

    Be careful not to use the X as that will delete the app from your phone, but you will be warned before deletion.

    If nothing is running in the background at all, then you might get a more accurate picture by recalibrating your battery.

    To do this, allow your phone to go completely dead and shut itself off. Then charge to 100% as normal.

    Yeah, I've closed all apps and will check back in 10 minutes. Usage should then be 10 minutes shorter than standby I would assume.

    Also, people were saying if you had a webpage open on safari, to close that out as well because some webpages make your phone always run.

    We'll see if this does the trick. Hopefully I don't have something running in the background I'm unaware of.

    You're assuming that the problem is an app working the way it's supposed to. I'd say it's good odds that this is not the problem.

    When my wife had this problem it ended up being her work Exchange account that was constantly checking e-mail for no reason. (There's no way to set it to do that...it was just a bug.)

    Someone else had a post here the other day where he discovered that a weather app was constantly checking the location...another bug.

    My point is, there shouldn't be anything using the battery like that, so whatever is doing it is probably a bug or a glitch. Thus, simply shutting apps down might not be enough. Whatever the glitch is, it could keep on going.

    Anyway, let us know what you find after your 10 minute test. We can think up more ideas based on what you learn from that.

    Yeah the closing apps thing did not fix anything. Usage and Standby times are still the same. Weird!

    I really have no idea what it could be. I just got this phone 2 days ago, so it's really all I know in terms of battery life. I did the reset where you hold home and sleep together and it reset everything so I can't read usage and standby times anymore until I fully charge it.

    Now I'm really just trying to get a gauge but I had all apps closed, turned off my screen at 63%... it dropped to 62% in 5 minutes of me doing absolutely nothing...

    Since it's so new, try doing a restore in iTunes and not from backup.

    I usually hate suggesting that since it's a pain to re-load everything, but you're just 2 days in so it's not the end of the world.

    Once that's done don't load ANY apps or set up ANY email or accounts or anything. Check and see if you have the problem.

    Then add an email and check.

    Then add iCloud and check.

    Then add Facebook and check.

    Tedious, but you might be able to nail down the culprit this way.

    IF you still have the problem right after the restore, take it back to the Apple store and explain what you tried and what it's still doing. It may well be a hardware problem with your phone.

    I'm gonna charge to 100% this afternoon and see if it's still doing it. If it is, then I'll try the hard reset thing and follow your advice.

    I'm coming over from an HTC Evo where the battery life sucked so even this so far with the iphone is good to me haha

    Well, I charged my phone to 100% and took it off the charger and it seems as though everything's working now. I did turn off some notifications on apps that I don't really need any notifications for. I took a glimpse a minute ago and had 1 minute usage time and 9 minutes standby. Looks like that reset I did earlier worked. Hopefully it stays this way... I'll keep a close eye on certain apps that could screw it up as well.

    Then try this solution:

    Go to Settings > General > Reset > Reset all Settings (this will not erase your data at all), however it does bring up iphone and the set up page once you reset but your data is still there. I read a few blogs about this issue that you have and the reset all settings did resolve the issue.

    Make sure fully charge the phone and then reset as suggested because once you reset, you may lose the usage and standby time.
