    I'm on iOS 8.4.1 and battery seems to be my only reason to upgrade to iOS 9.2, so I wanted to know if the battery is better or not cuz battery on 8.4.1 is awful and pretty bad...

    This is my 6s on 9.2 a full discharge since updating yesterday and charged to 100% overnight

    This doesn't look promising, hopefully this answers your question

    Location services off, Apple Music off, spotlight off, siri disabled, 3D Touch off...

    Honestly, don't update.

    My iPhone 5s had a better battery than with iOS 9. Moreover, I need battery saver on if I want it to last 5-6 hours (What iOS 8 lasted on my iPhone without battery saver // I have everything on )

    First 2-3 days typical result in poorer battery life as your phone settles in after the update. I have been on 9.2 since B3 and B4(Final) has the best battery life I have experienced on my 6s of any iOS 9 update. I easily get 10 hours on my 6s, with everything turned on that you turned off.

    OP: The reason why your battery is probably poor on 8.4.1 is the health of your battery. Check your charge cycle count and your remaining health. It could just be a dying battery.

    I normally gauge every update by 10% of battery per hour, so far most updates have been almost on par with that besides this one.

    Thats typically what I do too. 10% = 1 hours. 9.1 was awful for me, 9.2 is better than 9.0.2 for me and 9.0.2 was about the 10% = 1 hour. Now for me its more like 10% = 1.25 hours.

    And that is running beta. Went from 9.1 Final to 9.2 B3 -> 9.2 B4. All delta, no fresh install.

    Which was the last iOS 8 version you were on ? iOS 8.4.1 was reported that it had severe battery drain issues on apple's forums

    Check your battery health as I mentioned above. You can use Coconut Battery on a Mac for free. Otherwise the only other way is some paid apps in the app store.

    How old is your 5s?

    Using while charging does nothing. Over a long time, using while charging can cause excessive heat (depending on what you are doing) which could hurt battery health. But normal use while charging doesn't mean anything.

    Its all about cycle count and health.

    Hi,
    Just for my curiosity how do you use the phone, mainly, to achieve 10% per hour? I am able to achieve 6h per charge but with a totAl stby time of almost 3 days. No switch-off overnight.
    Thanks

    Well - First off what phone are you using and what OS are you on.
    Hardware + Software combination is very important. Additionally, I charge my phone every day. If you are getting 6 hours of usage and 3 days of standby, your battery sounds pretty strong.

    I usually plug my phone in at night with 7-9 hours of usage, 14-16 hours of standby and between 25-40% battery remaining. (iPhone 6s, running 9.2B4)

    I have 6s with 9.2b4 too but i was less convinced than you about the health of my battery. When i leave it on overnight it is in aircraft mode though and it loses 2% per night. WhAt do you think?

    Sounds like you have stuff running in the background that is eating power. When I leave mine unplugged overnight, not in airplane mode, I lose at most 1%. Most of the time I lose nothing.

    Thats just poor calibration (which I'm sure is within a margin of error) of the battery meter. But assuming "overnight" is ~8(hrs) x 1(%) = 800hrs = 33.33 days standby. Thats over 3x the standby time Apple rates the iPhone 6S which is 10 days.

    That looks amazing. What are you talking about? That's about 8 hours of usage. I'd have a party if I ever got that.

    8 hours hell no, 5 hours on screen. It seems percentages in battery on iOS 9 do not drain on a consistent bases it is very sporadic.

    A phone isn't a dog that needs to settle. Same BS as cleaning Dalvik cache on Android.
