    Hi All,

    After reading alot of advise on here yesterday, i decided to update my iOS build to the latest one and power-cycle the device.

    Here is a screenshot of my usage, can someone please help me establish whether or not it sounds abit correct?

    If you used it to listen to music for 3 hours, it's terrible battery life. If you used it to play Infinity Blade for 3 hours, it's incredible battery life. It all depends.

    Looking at your combined usage over the course of a day is not a great way to judge if it's working properly or not because different types of usage drain the battery very differently. If you spent the day on 3G and had a low signal the whole time your usage numbers would not look very good but it would be perfectly normal.

    I was curious about my battery life so I did some simple tests. Made a phone call to my home phone on a weekend and just left it going for 30 minutes. Battery drained 8%, which maps perfectly to the quoted "up to" 6 hour talk time. Did the same test with browsing over WiFi for 1 hour, playing a 2 hour movie, playing music overnight, and simply leaving it in standby overnight. You could try this and see how your battery life compares to Apple's specs. However make sure you first drain your battery fully a few times so you know that it's calibrated properly.

    Hi mattraehl, thank you for the reply,

    I can assure you, i have not played any music, any games or anything.

    All my usage is checking emails, making calls and texting via SMS and WhatsApp. Maybe used the camera to take 2 pictures.

    I really do love this phone but i currently have so many things turned of im only using half its features just so i can work a day without it dying, Siri off, location services off, notifications off, wifi off, bluetooth off, brightness low low low, vibration off etc

    What shall i do? im at a loss.....

    That's MUCH better than my battery life. I'm usually around 1% with about 4 hours of usage.

    Well based on percentages you would get 7+ hours of 3G usage over a 30 hour period. The quoted number is 6 hours, so I imagine having all those features turned off is where the extra hour is coming from? I don't understand what your problem is, it sounds like your battery life is perfectly normal if not better than expected. If you need over 7 hours of usage and your work days last 30 hours then I guess you should get a battery pack? Or try to charge at your desk or car when you get a chance?

    Does that count for the hours its on standby to? last night it was in airplane mode all night (6 hours), i switch it to that before going to bed to save battery.

    My point is... if i enable all the features like siri, location services and notifications, i wont get nowhere near that battery performance.

    All my mail accounts are set to manual search for email to, Push is off and Fetch is off for everything.

    You turned off lots of features, so you're getting even better battery life than what is quoted. If you turn stuff back on you will probably get "normal" battery life, around 6 hours of usage over a 24 hour period. You don't need to put it in airplane mode overnight - just plug the thing in and it will be full in the morning. Your battery seems fine, not sure what else to tell you?

    It's been 20 hours since your last charge, you've used it for almost 5 hours and you still have 35% of your battery left. Seems pretty darn good to me. People are obsessed with their batteries. Turn off the % indicator. In this case, it really might help you relax a little. There doesn't seem to be anything wrong with your battery life.

    I feel bad for you guys and your battery life. Here is mine from a day ago. I would consider this average usage for me.

    -Regular checking of twitter/facebook/feeds throughout the day
    -Sporadic web browsing (I won't even try to guess a total time for this)
    -Maybe 35~50 text messages
    -One 45 minute phone call
    -About an hour of iPod playing (screen off)
    -About an hour of Pandora streaming (screen off, wifi)
    -Few pictures taken
    -2 or 3 short youtube clips
    -About half an hour of playing Flight Control
    -Wifi was on about half of the time

    On a heavier day, I'd be streaming more, browsing more, and talking/texting a lot more (I'm relaxing on break :D ). The usage would bump down to about ~7 hours. Reception also plays a large role; I rarely have less than 4 bars.

    T-Mobile with 3G service... Where do you live?

    Yes tmobile has good 3G coverage in the uk but I refuse to go with them because the idiots cap the download speed at 950kbps/sec, pretty much 1Mb/Sec which is rubbish

    In my experience they only cap it when you hit your usage limit, so instead of charging you extra they just throttle you until your next bill.

    If you don't mind paying extra for going over your data usage, T-Mobile wont be for you!

    Thanks for the replies, all of the donkey work to get the new iOS build, fully discharge the battery and disable everything has indeed helped the battery performance out huge amounts.

    It would be nice to be able to have more features enabled, but i guess until Apple release a fix, i can live with it as it is :)
