    I can tell already that the battery life using developer beta 3.1 is improved.

    I have over 30 minutes of 3g and still at 90%. Before I was at 10 minutes usage and 90%

    You might have better battery life. I hope they improve the battery percent indecator. I think that is what you are seeing. A more accurate dispaying o the amour of battery left. But yeah, updates do improve the iPhone/iPod's battery life.

    In a couple hours you decided it had better battery life, you're full of you know what. You don't know if the OS just reports back differently now or what. Just like when 2.1 came out and everyone was reporting better signal strength. But there was actually no difference when you looked into it via field test.

    Hey Jeremy, F*** off

    The battery life is better.

    There are different ways of going about this, but I do agree with Jeremy here. You've really no idea about the battery life. Whenever people do an update, they automatically scream out that they have better performance etc etc, when really... it's a placebo or the fact that they've essentially reset their device, hence the speed increase.

    iPhone os3 beta 1 has better sound quality

    I listened to one song and I swear it sounds better.

    I am a developer and just put on 3.1 beta and on my 3GS the battery life goes down at roughly 5% per hour.

    Doing a full charge as we speak and will report back my findings but I do agree with the others here just 30 mins or so does not qualify really better battery life.

    Too many things like signal strength, location, come into play.

    I think I would give him the benefit of the doubt.
    If not for
    10 minutes and already at 90%? That doesn't seem right. If it were using that much power it would only last you about 2 hours. Sounds like a problem with battery or some software stuck in a loop wasting CPU power.

    I have found it to be a lot faster on my 2g iPhone too!

    Safari is definitely snappier! (Joke...).

    It could simply be self-delusion with regards to battery life. It doesn't seem to be tested in an controlled environment either. A larger sample is necessary to get any conclusive data.

    Such an intelligent and well-put argument. Bravo, mmoran27.

    Well after 1 hour of standby and just 20 mins of use with WIFI turned on the battery has gone down from 100% to 97%

    It's a bit early to tell but I think the battery life has not improved with this beta but only time will tell.

    These are enabled on my phone

    It may not be better for everyone but it is definitely better for me

    I was getting 3.5 hours before of usage.

    This is only email and safari.

    At this rate I will get about 5 hours.

    I included a pic so it did happen.

    I think what you’re seeing is a more accurate percentage indicator, not necessarily increased battery life. I had also read somewhere there was some sort of power management package included in the 3.1 SDK but I haven’t been able to confirm as of yet.

    Whether true or not, this made me laugh out loud.

    Where bunnies are welcome.
    It would be nice if those reporting better battery life, would mention whether you're on the 3G or 3GS. I'm interested to know if OS 3.1 will help the 3G, whose battery life has much to be desired
