    man my battery life is like the same no better
    Agreed. Battery life on 3GS is comparable to what I was getting on my 3G.

    It appears that Apple are on the case! They have an APP that monitors complete usage

    Cannot paste link as i have not posted enough on the site so go to HardMac and search 3gs battery life
    How do you get that application? That would be really interesting to see. Can you just download it from the App. store?

    This is my first iPhone so I can't compare it to the 3G, but it can last half a day with 4-5hrs of data use, very little phone use. I have bluetooth & wifi turned off, brightness down to 1/5, 3G on, and today I turned off push and put the fetch setting under manual. I've only drained the battery to death the first day and since then I've been charging at 10%.

    It takes some getting used to when you unplug it at 100% and after going online for a few minutes, you're down to 98%.

    Today while taking the subway, I was reading a book on the iPhone and thought, why waste energy looking for a signal? So I put it in airplane mode while I was underground. I don't know how much battery life that saves, but I'm underground at least 40min a day.
    So basically turn off all the features of the phone to use the phone.....that's what I don't want to end up doing!

    I don't know why, but for some reason my white 16GB iphone got horrible battery life. While browsing the internet in the car on the way to work I could deplete the battery by 10%. I just yesterday upgraded to the black, 32GB version and I am getting MUCH better battery life. Seems like some quality control was not going on to make sure all these batteries are good.

    I had my music on all night and left it not charging cause I am an *****.
    Anyway when I woke up after about 12 hours of sleep I had 59% battery left.
    It's actually kind of impressive to me.

    My battery life is great. Unfortunately the battery % counter is of the devil. I really didn't pay much attention to the battery life until I found that thing.

    Is BT, WiFi, and location on? Are there any apps that you might have on in the background hogging battery life? Try reseting the device holding the home button and power button at the same time until the system powers down and you get the apple logo.

    I've got to charge my Storm daily. My best friend, who's an iphone user (3G, not S) always complains about his battery too. I think smart phones in general are tough on batteries and then when you add a large graphic rich screen, it can only get worse. I'm happy with 1 whole day on a charge thou, just got to remember to plug it in every night. Plus a spare battery helps too.

    With the 3.0 upgrade alone the battery is not a problem anymore. With the 3GS it's even better.

    Please stop complaining and also if you jailbreak your phone your battery will not last nearly as long.

    I have spent months testing this out and I'm sick of people complaining.

    Its what people tend to do

    Certainly battery life is one of the main obstacles for me to overcome in buying an Iphone

    I have had similar problems with every iphone I've had. You just have to let it run ALL THE WAY out and then recharge fully for about 3-4x. Then - voila! It'll work like a charm!

    Ok, what exactly is it about jailbreaking that sucks power? I can see how certain modules (eg multitasking) might do it. Is there consensus on this in the group? I had the same suspicion under 2.x firmware so I un-JB'ed, but I thought I'd try again when 3.0 came out. I didn't gather any empirical data on battery life with and without JB. Does any such data exist?

    Settings can help too, for example, turn off stuff not in use like wifi, gps & bluetooth. Turn down the backlight, etc

    That damn battery % meter is what's killing me. I'm checking that thing like mad, it makes it hard for me to enjoy this awesome device. I've only let it die completely 1 time though. Maybe after 2 or 3 more it will give me some better results.

    Ive just finished my initial 3 cycle drain and I have been getting some really good battery life.
    3g on, wifi on, bluetooth on GPS on, push on, notifications on, fetch every 15(8 accounts), Screen Brightness 100% with no auto feature and I am getting about 5 hours of usage,(watched 2 full baseball games over wifi, games, texting, twitter etc). I usually have 3g off, GPS and screen brightness around 40% so I am very happy. Ill report back after a day of normal use not trying to drain the battery.

    Ok after a week with the iPhone 3G S I have an important tidbit about the battery that we should all know.

    1. It charges significantly faster via the AC charger, and you may have some old iPod cables around but make sure you are using a newer cable (the ones with the short heads) for faster charge and sync and less compatibility issues.

    2. Once you start charging from AC, it will last longer. Believe it or not, from my use, it is true. I haven't been charging it via AC and the battery has been lackluster to say the least. It hasn't been any better than my 3G was (which I charged every day via AC). I haven't been charging the 3G S with AC because I've been using it a lot at my computer because it's new and I've been playing with it at home.

    After giving it a full charge last night via AC, I went out today for 8 hours (from 12pm to just now when I got home) with mild GPS usage, 3G on, iPod on for a good chunk of time... And I still have 50% battery left. It is actually very impressive compared to other days when I'd drain it to 50% just by playing with it for an hour or so in my living room.

    I believe with these batteries there will be a peak time, And also a period in which it, in a sense - warms up.

    Today I was constantly on maps, twitter, 3G network surfing the web and the phone was pretty much dead by mid afternoon. But it saved my life today- makes exploring NYC so much more easier.

    It's nice having so many people's input on this particular issue. I'm about 99% sure I'll be getting the 3GS in Sept when my bday comes around, but I want to make sure it's not something I'm going to be unhappy with. Battery life is an issue for me. When I'm in college full time, away from home, I need something reliable that will last me through the day until it can be charged again.
    Most of you may know about the Curve's battery life capabilities, and that is one thing it looks like I'm going to be missing.
    However, I've seen a lot of posts saying the life gets better over time for the 3GS. So hopefully this is true and will set my 'fears' to rest.

    Ok so im stumped. I had success with the above options turned on getting easily 5 hours of battery life.

    Today I turned off: GPS, 3G and reduced my screen to 50% with auto dimming on. I get 3 hours 20 minutes with less agressive usage. WTH?
    I have to try this again. very strange. If I have to keep everything ON to get 5 hours, sweet!

    The battery life is more or less the same in real world usage.

    I have brightness set to default (50%), wifi and 3g on constantly, as well as location services and push email turned on. These are roughly the same settings as I used to have on my old 3G, except I am running the screen at a brighter setting on my 3gs. Even with the brightness set higher, the 3gs has significantly greater battery life than my 3g (15-20% better, I'd say).
