    I just read this off of iFixit's site and it seems the 3G iPhone battery is lower in mAh than the original iPhone. 1150 as opposed to 1400. The battery pack is also supposedly smaller than the original's

    Most likely.

    Apple introduces the original iPhone. Its expensive, but well built and amazing. They establish a good name for themselves.

    The second generation is much cheaper so many buy it, but not as good in terms of quality. Apple exploits the great brand name it has built itself to sell shoddy products.

    Cute coming from someone who doesn't actually own an iPhone (and probably jumped on board with their college Blackbook/iPod Touch purchase)

    Just to throw this in here: The original iPhone had a talk time of 8 hours of 2G talk time compared to the iPhone 3G's quoted 10 hours. From that I gathered the new iPhone has better battery life?

    Perhaps it has a smaller battery but a more efficent chipset?

    well you guys would have to but the phone on edge for about a week to test the battery life for real and it does get a good 9-10 hours ON EDGE. They said 3G is 5 hours so people think the battery is less capable then the first iPhone.

    I believe it is less capable. I used to get 2 days use with my old phone with my usage pattern.

    This new phone gets maybe 1 day. That's with 3G and gps off. I even set fetch to 30 min instead of 15 min like I used to have it.

    I did an informal test myself over several days and found that the talk time was considerably better on Edge. In fact, the battery life is so bad after heavy GPS/3G usage that I usually switch to Edge only at the end of a long day. It usually works to extend the battery life considerably. If the battery IS smaller than the components are considerably more efficient.

    All that being said, it wasn't until I got an iPhone that I understood how five hours of usage from a phone could be severe limitation. I flat out never used another device like I use this phone.

    I also find that Edge isn't as slow as I thought it would be, esp since here in NYC the 3G network gets pretty saturated and slows down to a crawl. The iPhone is worth every penny I paid for it--unfortunately since its tied to the AT&T network its not worth every penny I didn't pay for (the slavery of the subsidy).

    Thats just what Apple quotes though, real-world usage is highly likely to be different

    im just sick of people complaining and not expecting a battery around 4-5 hours. I THOUGHT they were gonna have like a 4 hour 3G talk time battery. My 2 symbian Nokia 3G phones would only last 2-3 hours with data on. People have to understand that we use the iPhone for data a hell of a lot more then on other phones, well at least myself!

    *cough*

    I was the one who pointed iFixit (and through them, everyone else) to the 1150 mAh battery with that part number.

    No one still knows if that's correct.

    More interestingly, someone else has pointed out that the part number for the original iPhone's battery, relates to a 1280 mAh battery, not the 1400 mAh that was first spread around everywhere as "fact".

    1280 down to 1150 would be a much smaller difference.

    (If ArsTechnica and the other pseudo-scientific sites were real, they'd take out the batteries and do some actual amp-hour analysis on them.)

    Interesting...i wonder why the numbers are different. Here on iFixit's site their replacement battery for the original iPhone is 1350 mAh. It also looks the one Apple ships out(Pic 1)

    Another site called iPaq repair & parts says it offers a 1400mAh replacement battery and their battery also looks very much like the one that Apple ships out (Pic 2)

    Brando also claim to have 1400 mAh replacements (which is clearly marked at the top right of their battery (Pic 3)

    Finally iPod Juice claims to have a 1400mAh batter for BOTH the original iPhone & iPhone 3G. (Pic 4)

    Hard to tell which is the real thing with all the discrepancies

    i wonder why apple would put a lower capacity battery.

    maybe theres less internal room inside because of 3g and the gps chip?

    It could explain why the battery pack is thinner than the original iPhone

    My 3G iPhone barely lasts a day of use with the same usage pattern as my previous phone. I turned 3G off thinking it should bring it in line with my old phone but I still hit the 10% warning by about 8pm most nights.

    I don't think that's normal man.

    I don't get a 3G signal in my town, so I have EDGE on, with some GPS usage (I turn it off afterward), and I get better battery life than on my original. On my first gen. I would get about 5-6 hours, and on the 3G with occasional GPS I get 6-8.

    Now, if I have Push on, GPS on, and 3G on, I only get around four hours of battery life, but with everything set up like the original iPhone, I am getting better battery life.

    Have you turned off GPS? The GPS chipset seems to suck out more juice than the 3G chipset.

    The drawback to turning off GPS of course, is that it will take longer to give you a precise location fix - up to a couple of minutes - whenever you need to use location services (as opposed to it being always on and thus, always knowing where you are).

    Where do you turn GPS off? Is it just that Location Services switch?

    Yes it's the location switch.

    Is the general consensus here that if you use a 3G phone like a 2.5 G phone (Location OFF, 3G OFF, PUSH/FETCH OFF) that you will in fact get better battery life on the 3G phone than on the 2.5 phone? In other words if you cripple the 3G to work just like the original 2.5phone, do you get better battery life than the original?

    That is what Apple claims. My experience has been anything but. On my 1st gen iPhone I would typically get around 6 hours until the 20 percent warning. This was with talking, fairly heavy internet use via Wi-Fi, and and considerable amount of video watching (movies). My 3G will, at very best, last until 5 hours...total shut down.

    I am seeing roughly a 1 to 1.5 hour discrepancy between the two. I'm not happy about it either.:mad:

    I'm getting less battery life on the 3g than I was getting with the 2.5g iphone.

    I've had to adjust which features I use in a day, and bring my connector to work so I can charge it at work.

    I own several of both and that statement is just plain ridiculous.
    The build quality is better in some ways on my new 3g than my original.
    I could use either phone and I choose every day to pick up my 3g,
    although I still love my 1st gen.

    That's even if you cripple all the 3G features and use it like a first gen phone?
    If so that is deeply troubling!

    3G has, unfortunately, always drained the battery more readily than when without 3G.
