    I recently got a replacement iPhone 4S, after my old one got stolen. I previously had to recharge my phone every night to make it through the day, but with the replacement phone this seems to have changed to every second day (maybe even every third, but I haven't tested that much yet). I've successfully tried this twice now, which I never ever did with my previous two iPhone 4S models I had. At the end of one normal day I had 80% of the battery charge remaining, while after a day of heavy usage it still stood at around 70%, far more than the typical 50% that i had on my old iphone 4S.

    Anyone have any leads as to whether Apple is now using the 32nm A5 chip for the iPhone (as with the apple TV and ipad 2)?! Or has Apple even switched to an upgraded GSM chip?! Unfortunately I'm not curious enough to take my iPhone apart and dismantle the chip to see for myself..

    Getting too complicated. More probably to do with OS version and a fresher (less charge cycle) battery.

    Without a FCC filing it is impossible.

    So if you get better battery life it means it has an A5 chip?

    The 32nm A5 is a single-core chip. Currently the only item this has popped up in is the AppleTV.

    If I remember correctly, the A5 in the Apple TV is a dual core with one core disabled..

    I remember this as well, one core disabled. For the OP, it most likely is the new battery in the replacement phone. I'm going to have to get a replacement as my AppleCare nears its end in November date as well. It's not completely horrible just yet, but I know it's coming. I also, like many, have to charge every day and most of the time twice daily - such a pain, even with two wall chargers, a travel charger, and a car charger. SO MANY CHARGERS...

    The old one was. The new A5 (the 32nm one) is a regular single core.

    A big change came with iOS 6.1.3, significant better battery life, so I would back you up on this.

    Apple would never do that. they wouldnt release a 45nm iphone 4s, then a year and a few months later release a 32nm version to improve battery life and other things like that... 4S owners would be outraged and they would get lawsuits

    Has to do with a brand new battery/phone, and a clean install of iOS

    They did just that with the iPad 2. Plus its cost savings for Apple as the 32nm chips are cheaper to produce.
    Ps: my old iPhone was 3 months old (button damage), so I don't think the battery had much of of an impact over the course of that time.

    Lawsuits for what?

    That is how a company like Apple test a new processor out.

    They did it with the AppleTV and iPad. There are 32nm model iPad 2's being put out now that get better battery life then the original.

    That's the point of this thread.

    OP. download linpack and compare. I have an iPhone 4S from jan 2012. It's a iphone4,1-N94AP/ 2 cores.
