    Is anyone noticing any real significanct battery uptick if this feature is turned on?

    I can't say as I have the 6S Plus and haven't found any use for this feature yet. With 60 hours of standby time I doubt I ever will, lol.

    Lot 23E. Somewhere in Georgia.
    I've used it a few times doing some gaming in my 6s+ (minecraft, which is very battery hungry). I haven't measured battery difference but the phone is noticeably cooler when low power mode is enabled during gaming.

    My guess is that it significantly reduces battery consumption, but it kills a lot of functionality to do so, so I only use it selectively.

    Same here. In my worst day so far I have only made it to 20% remaining so I have yet to use the feature much. Saying this, I should have held out on a reply in this thread since I'm not able to answer the question. Ha.

    I see little use for this feature when the battery is so good on my S+.

    I'm feeling the same as almost everyone in here. This 6S+ battery is pretty hard to kill with normal usage. I can see low power mode coming in handy during an extended power outage (like Hurricane Sandy level storm), when charging phones actually became an issue. During that storm my only fallback was charging my little Android phone in the car. Now i've got a killer battery, a 3100mAH Anker external battery pack, and low power mode. Life's good.

    I have most things switched off already that low power mode switches off. The only thing it would do for me is lower CPU speed, but having a 6S+ I haven't ever needed to try. It's a nice thing to have in the locker for emergencies.

    I agree with what all of you are saying, but i did have to save battery for a few hours and i only had about 10% left. I had Auto Brightness off, brightness all the way down, grayscale on, and low power mode on. My battery lasted at least 2 hours.

    From what I know so far from a user perspective

    1) Autolock set at 30second to avoid screen left on too long.
    2) Background app refresh is disabled [this is usually a battery killer if u didnt customize what apps u like to constantly update and rely on].
    3) 3D touch for live background doesnt work.
    4) Perspective mode [the tilting phone to get a parallax/tilt effect of background] is also turned off. => Your wallpaper is in still mode.

    There was an occurrence last week at disney where I was down to under 10% on my 6s+ battery. It got down to 3% and I turned on the low power mode. Made it another hour and half doing video/camera/disney app and got back to the hotel with 1% left.

    Worked well for me.

    If I were a full day at Disney I would have considered turning it on at the start of the day. Lots of reasons to use a phone there.

    When turned on earlier it usually gives a more noticeable increase in battery life.

    On my 6, I've found that it makes little to no difference, but that may be because I take many battery saving steps already anyway, such as turning off background app refresh and push notifications. I'm pleased with the battery life I get whether low power mode is on or not.

    At what battery percentage/level have you tried enabling it?

    For testing purposes I've run my phone down from 100% all the way down to about 20% on low power mode the whole time. No significant difference than when I run it down normally.

    Interesting. I've done it like that a few times and usually would have more than an hour or so of usage and a few hours of standby by the time I'm around 20% compared to being without LPM.

    As I said, I cut out a lot of the background activity on my phone anyway. For my usage, I don't think that there's much more that LPM can cut down on.

    As do I. I don't have background refresh enabled, I only use fetch for one mail account that I have (set to 1 hour), have motions reduced, have pretty much all system location services disabled and most of the apps as well (aside from some that need it only while they are being used), etc. One of the main things that LPM cuts down on is CPU and GPU performance (in addition to lowering brightness and setting a 30 second auto-lock timeout and various other things that we mostly have enabled too).

    In front of my computer
    I used it on both my 5 and 5s for a time but turned it off as it made zero difference with battery life.

    I don't usually do anything cpu intensive so that's probably another reason why there's not a pronounced difference for me.

    Yeah, neither do I really mostly using the phone, messaging, email, Safari, a few social apps and the like. Everyone has their own experience I guess even with similar overal type of usage and setup.
