    hey guys, so i have a quick question ,since the low power mode is supposed to extend our battery lifes by quite a bit, what would happen if i always turn on Low Power Mode all the time? i dont notice any slowdowns on my 6s with the low power mode enabled, so if it'll allow me to get better battery life i might as well keep it enabled at all times?

    It would extend your battery but I would imagine that it would reduce some functionalities. I know I've read some people doing that and from what they wee saying it made some UI components less crisp like for example reduce display brightness.
    That's what I remember. I haven't done it.

    If you don't mind or aren't really affected by the things that it does to conserve power (like not using push or fetch, turning the brightness down some, disabling animations, shortening the auto-lock time, turning down the CPU power to some degree, etc.) then you are getting the extra battery savings without much of a downside.

    Certainly can experiment and see if there is a downside for you. Try it and let us know. I think one annoying thing is the lock timeout is very short. Ymmv.

    Your better off just using it when your prompted at the 20% and that last percentage will be like double the battery life

    You'll actually get more of a noticeable benefit turning it on earlier in cases when you might need to preserve as much battery as you can if you can foresee that for a particular day or time period.

    Ok I will give it a try for a few days and see

    One question regarding push notifications, I have push notifications enabled for Instagram and Facebook, my question is: is having push notifications enabled for these 2 apps lowering my iPhone 6s' battery life or it would be the same regardless if push notifications are enabled for Facebook and Instagram?

    If they appear on the lock screen and thus turn the screen on perhaps often then it can add to the battery usage from the point of view of the screen being on more often (and sound/vibration coming on perhaps). Otherwise, not really much of a noticeable impact.

    difficult to say. If you have background app refresh on (which you won't if you have low power mode, but anyway...) then notifications - both visible on lock screen and silent, invisible ones - can initiate background refreshes which can use more battery. and as C DM notes, any notifications that wake the screen will use a bit more battery too in powering the screen

    however, merely enabling notifications for them doesn't use more battery in itself, as the notifications will come through the same channel from Apple servers that is already established for other apps. it will depend on how many notifications the app sends. and you may have heard about Facebook using a lot of battery... however all that potential extra battery use should come under the app in the battery section, so you can always try it and see.

    It turns the CPU down quite a bit. I saw a little while ago someone benchmarking a 6s with and without Low Power Mode and it basically makes the A9 run like the A8. Which is a pretty significant decrease.

    To the OP. It's not really worth it to run LPM all the time because of the above. Otherwise why spend the extra money on the 6s only to basically turn it into last years 6. The better approach would be to manually turn on/off most the things LPM does on your own. That way you would get most the benefits of Low Power Mode and not throttle the A9 down.

    I'll only use it if I'm out in the wilderness with a broken leg and need to inform the authorities of my location, ie when battery power is indeed a life & death situation.

    I have background app refresh OFF and i get whatsapp, facebook messenger, viber etc notifications istantly, like it was on. so you can safely turn it off.
    I would tweak your settings and see how it goes.
    I have bluetooth off, location off unless I use maps, background app refresh off. thats more than u need to have a good battery life.
    if its not enough, then try to turn on the saving mode and see the difference.

    It turns it down by around 1/3 of its power or so. If you are mostly doing things like calling, messaging, email, safari, and a few apps that aren't heavy (like some social networking or sports or weather or the like) you likely won't notice any difference.

    Why can't the phone downclock the CPU until it's needed, should be a stock feature.

    I'm sure that is the case, however, I can only guess "low power mode" is equivalent to "power saving" on windows and locks the cpu speed to some arbitrary low number (plus other things). You can feel it as the phone feels a bit sluggish.

    It could work like Intel Turbo Boost, instead of boosting the frequency keep it the same but just down lock for low level tasks.

    I use it while I'm at work, & have no access to a charger because I'm always on the go. It doesn't really change anything to me. Id recommend keeping it on

    In that case it's probably wiser to toggle airplane mode.

    These of you that wonder why I asked this question, well I have the new 6S(not plus) and I have an Apple Watch as well so I have Bluetooth on all the time on my iPhone for it to be connected to my watch, so my battery life so far is not great at all, thanks for all the suggestions by the way.

    How do you guys cope with the rather bad battery life?

    Bluetooth is low power and shouldn't be draining the battery much. Many people don't have bad battery life. What do you typically get as your usage and standby times by the time you are basically out of power?

    It would involve a bit of switching my phone off completely, running low power mode, and short bursts of full power 'where the heck are you all??' activity.:D

    Well it should be low power but in real world usage from my experience the battery drains considerably faster when Bluetooth is on.

    I find that LPM is more seemingly power efficient once it is turned on at 20% or below, rather than at a higher percent.

    I find that I get more out of it enabling it before. It still provides savings at 20% of course, but they are more noticeable if enabled before.
