    Hello, I'm new to the forum, and tried posting my issue on the Apple Support Communities, but haven't gotten a response yet, so decided to try asking you guys for advice/help.

    I wanted to see if the usage of my phone is normal or if my battery is dying quicker than others?
    Sorry in advance for the really long post, but just wanted to be as specific and detailed as possible so that someone can advise on if my battery is underperforming or if the battery is normal.
    I just purchased the iPhone 6s, 64gb, which I received on Friday, but had to exchange it out for a new one on Sunday because I was having battery issues. (Phone battery went down 30% on standby within a span of 5 hours, which I know for sure wasn't normal, and the phone dying within 6 hours into the day with very light usage).
    The newer phone's battery life seems to be a lot better than the previous, but I still seem to be having issues.

    I've been monitoring my phone since Monday.
    I took my phone off the charger at 12:00AM, 100%, then went to sleep and woke up at 8:00AM and the battery was down to 93%. (Wifi was on the whole time)
    Then I turned off the wifi, left for work and I have wifi turned off all day at work.
    Got home around 5:36PM, battery is at 6%, turned my wifi back on, at 5:45PM battery went down to 3% and then I started charging it.
    So the overall usage/standby time I got by this time was Usage: 6hr, 28min / Standby: 17hr, 23min
    Then my phone charged to 100% by 8:15PM, went to bed at 11PM, battery is at 75% by this time.

    Tuesday.
    8:18AM, battery down to 66%.
    By 2:42PM, my battery is at 3% again, so started charging it.
    Total usage/standby: Usage: 5hr, 56min / Standby: 18hr, 26min
    By 5:10PM the battery is fully charged.
    5:32PM, I'm home, turned the wifi on, still at 100%
    6:45PM, 87%
    8:53PM, 54%
    8:53PM-9:22PM-Used the phone straight for 31 minutes, testing out battery life with brightness level at 50% & 80% brightness.
    9:22PM-48%
    9:35PM battery is at 45%, put it on the charger.
    Total usage/standby: Usage: 3hr, 43min / Standby: 4hr, 23min
    10:05PM, battery is fully charged, unplug, change brightness to lowest, then it's on standby until the morning.

    Now it's Wednesday,
    8:08AM, battery down to 95%
    8:40AM, got to work, 92%
    10:47AM, 72%
    12:47, 67%
    Total usage/standby: Usage: 2hr, 45 min / Standby: 13hr, 57min

    Other information about phone: Software is up to date, 9.0.1, I have good service at work, always 4 bars(T-Mobile), my brightness was at around 75-80%, sometimes 50% while charging it (if I remembered to lower it) on until Monday-Tuesday Night, Wednesday it's been set to 50% brightness, wifi calling is on at home because I do not get any service, bluetooth is turned on all day, turned off most of my push notifications and app refresh, Hey Siri is also on.

    Sorry again for the ridiculously lengthy post, and thank you to whoever read this whole thing.

    Hope to hear from someone soon. D:

    You are obsessing over this WAY too much. There is nothing wrong with your battery.

    Check your settings. It may be some app(s) that's constantly doing something in the background.

    Check battery usage to see offending apps and their % of drain
    Check Location Services to see what apps are requesting (I disable almost every app from that except actual ones I'd use location services on)
    Check Background Sync and stop any apps you want from using data in the background
    profit.

    If you use Facebook... it's always been an offender, especially since they removed the various sync options of it so you can't disable auto-refresh. Unless they just moved it and I didn't find it. If you use facebook try using the mobile page instead.

    Thank you for the response.
    Well, before I started monitoring it, I did some research, looked at other people's average hours they were getting out of their phones, and most were getting at least 8+ hours of usage.
    And yeah, I'm definitely going to obsess over it, especially if I paid 800 bucks for the phone, which isn't considered cheap to me.

    I've pretty much checked all my settings prior to monitoring it, and most of my app refresh and location services are off.

    Most of my Locations Services are off, or ticked on "while using" and those are the ones I use most of the time.

    Usage right now is at 4hr, 13min with 42% battery left.
    Top 4:
    Facebook 23%
    Safari 18%
    Snapchat 16%
    Google 10%

    Yup, most my Location Services are off or on "while using." The ones that are on, are the ones I use most frequently.
    And most of my background sync is off as well, unless once again they're apps that I use the most.
    Facebook could definitely be the culprit in guzzling my battery. It seems to be the app that's always at the top of my battery usage. :/

    -------

    Thanks again everybody for the input, really appreciate it!
    Just all in all, is my battery life acting normal? Or does it seem to be dying a little faster than it should be?

    Just finished my first full battery drain on an iPhone 6S running IOS 9.1 Public Beta 2
    Restored from iPone 6+ when received
    Little over 4 hours usage
    Little over 88 hours standby
    Screen medium bright

    I am a light user and these numbers are acceptable to me. I suspect I could easily get 8 hours usage. I do see a bit faster drain browsing, but that seems to be lessening. Lots of bluetooth music play through my car, and so far that bluetooth connection seems better than IOS 8.

    Did you setup as new or restore?

    With these types of problems do a reset all settings first. You won't loose any data, apps or saves. Just gives it a clear out.

    So just at the point I want to charge the phone after having it for a day and a half. 16 hours standby and 3.5 hours usage at 56%. Not sure how to gauge this.

    Anyone running beta software should expect battery life to vary wildly.

    On a regular 6s you should see a 10% drop in battery for every hour of use. That's Web browsing, Facebook etc. Games will rinse the battery way quicker.

    Also, your battery is new. It will get better after a few more charge cycles and no doubt you are playing with your shiny new toys way more than before.

    Your phone seems fine based on that usage, screen brightness is probably too high. Try turning that down some, but using Facebook that much will kill anyones battery.

    I restored it from my iPhone 5s.

    So my battery life is considered normal?
    I already got my iPhone 6s replaced on Sunday (received the first one on Friday), so I haven't been using the replaced one like crazy, just normally how I would with my 5s.


    I left my brightness on around 50% yesterday and today, but still not getting a lot of usage on it. But who knows, I'm probably just trippin' out because I wanted this phone to be nothing less than perfect. Too high expectations, because the battery life on my 5s was pretty decent. xD

    Sorry, I just realized you said I should be seeing a 10% drop in battery per every hour of usage. Mine drops around 20% for every hour used, so I'm guessing mine isn't normal?

    I'm curious too. I had a 6s with great battery life but a dead pixel. Returned it and got a new one and the battery isn't good. I have attached a screen shot. Suggestions?

    How much battery usage/standby were you getting on your previous 6s?
    Here's a screenshot of my mine right now too.

    I was getting to 50% 3.5 hours and even a little better. Not sure if I should give the battery a few days or even a week or just return it and gamble on another one. This screen color is great no bad pixels. I returned the dead pixel one and got a phone that was super yellow tint and now I got a great screen but seems battery might be questionable.

    Those two had FX serial and this is DN

    It really depends on your activities and provide network condition.

    I know dude. But I'm just looking for to compare some settings..

    My first battery cycle (out of box and charge 100%) lasted 9 hours and 30 minutes. After that the maximum than I reach was 6h35m.. so I guess it was some setting that modified.

    No phone is going to go 8 hours of straight usage one a single charge.

    If you want to test if your phone has a bad battery or not. Don't use it. On standby its going to drop very little. I'm talking like 10% over the course of the day. That would be my first red flag if a phone, purely on stand by, fell from 100% to 80%

    So what if you literally can't leave your phone alone for an entire day? Charge it up to full and don't use any games or streaming video or videos in general. All you will do is message, call, light social media at every hour or 30 minute interval. You don't need to reply to that text right away. You don't need to check fb every 5 minutes. I expect your battery life to go from 100% to 70% by the time you get home start using the iPad or iMac or TV and at that rate, you have a good battery.

    Battery life is hugely affected by that screen and by the CPU usage. The more screen on time you have, the more battery is drained. And the longer you have intensive apps running, the more battery is drained.
    Only the obscene background apps will hurt your battery life so micromanaging things like location and background app usage is treating the symptom not the disease because those things actually take up VERY VERY little energy, less than 1%
