iPhone 6s with Force Touch = horrible battery life?

    With all this glory about the up-comming iphone 6s with the magical force touch AND (probably) slightly smaller battery... isn't anyone thinking that the iphone 6s will be the iphone with the worst battery live in history?

    The force touch (as I assume how it works) will use some battery-juice for the user-feedback-method (vibration). So by each force-touch usage the battery will drain faster than on the traditional method (<iphone 6s). Together with the same battery specs (or slightly worse) this will create some real ugly battery-usage!

    I really hope Apple has something up on their sleeves to tackle this and provide the iphone 6s with enough battery juice (because current iphone 6 have a rather mediocre battery live at best).

    -Just my 5 cents!

    You are probably right. I'm sure they never tested this at all while spending millions upon millions in research & development. They probably said "oh it should work decently" and left it at that.

    I'd like my nickel back!

    Why do you think iOS 9 gets you one extra hour of battery life and has a low power mode ? :p

    We have no way of knowing this, it's all hypotheticals.

    Who knows, we might see improved performance over the 6/6+ with the 6s/6s+ even with the new mechanism with a more efficient A9 chip etc - who knows.

    OP you're forgetting that the new A9 chip is more efficient than the A8. 6s battery life won't be any different than the 6.

    I think it's difficult to judge. The only fair comparable device with force touch is the watch and there has never been a model without it to compare with. I can't see it making much difference myself.

    I hope you're right. This "oh it should work decently"-thinking is what you experience in the android-universe (and I'm fed up with that). Yes, I'm planning on switching from Android to Apple.

    That's a valid point. Nevertheless, the real battery consumption is always with the display and since you will be using that force touch also often (what I assume) it might be another big battery-eater... but we will see/experience it soon :)

    Don't think anyone will know until it hits the shelves.

    1. Force Touch + Force Taptic didn't cause the rMBP battery to be worse, it remained mostly the same or more.
    2. It didn't do a bad job on the Apple Watch either
    3. iPhone already had vibration for years. Turning it off didn't cause the battery to increase much.

    A highly-specialized sensor do not eat up a lot of battery life like you think it does, it can be almost nothing in most cases. For an example, the iPad Air 2 has a more sensitive Touch sensor (120hz instead of 60Hz sampling rate) that surely sounds like it should eat up more battery life compared to the 60hz sensor in iPad Air and yet, it didn't cause any problems. Apple Watch has a lot of real-time sensors going at the same time and yet, it still can last a day for most people.

    A lot of the components are going to be more efficient in iPhone 6S, for an example, the radio chipset are being reduced from something like 6 components to 2-3 and has been processed on a 20nm process instead of 65nm process. The enough savings from this chipset would negate the extra consumption of the Force Touch sensor.

    Surely there won't be that issue, as Force Touch on the iPhone won't need to vibrate. It just measures the "depth" of the press. Or if it does vibrate, it'd be more than likely to use the built in vibrator. Even then it wouldn't be unlikely that there would be a Force Touch Settings menu which would allow you to disable the vibrations.
