    Here are two pictures, the first picture being my old phone and the second one being my new one.

    I have had my new phone over a month now and the most I can squeeze out of it is 8 hours. What's going on, does this qualify for another replacement??

    Low signal really kills phone batteries. That may be why yours is so awful in the second picture.

    The first one is the same, I get low signal where I live in general so I don't think its that.

    I used to get 11-12 hours out of my 6+ on 8.1.1 with two dots of reception the whole time.
    Now I get 9-10 hours with 8.3 and the same two dots of reception. I'm not disputing that low signal strength contributes to battery drain but it's only when using the phone for calls. The difference otherwise is negligible, not hours and hours of usage time.

    What do I do? I'm really gutted about this because this phone has been perfect. Not a single crash.

    Apple watch app 3%? Do you have an Apple watch?
    You also have Bluetooth on with the second stats, but not the first. Is it possible that your usage patterns are different to how they used to be and that you are actually draining the battery at a heavier rate than you once did?

    Your bluetooth and location GPS icons are lit up. Are these on all the time or just at the time you took the screenshot?

    They seem to be on all the time actually!! Just noticed

    I will be getting a watch soon, so shouldn't I keep blue tooth on regardless?

    There's your drain then (the GPS primarily). Switch the bluetooth off and work out what it is that's causing your location services to be on all the time. It will be either an app or an iPhone system service. Experiment until you find the culprit.

    ----------

    You can do but I would switch it on when you actually get the watch. The primary battery drain will be the GPS if it's on all the time.

    Thanks a lot for your help, hopefully this will improve my battery life and get it back to where it needs to be. Turns out the biggest culprit for location services always being in use was the Apple Store app. Couple other ones too but the location symbol disappeared when I switched off Apple Store location services.

    Everything else k have just switched to "while using the app" I hope it helps :)

    Awesome. Do a hard reset and see if things improve.#

    Your usage is different in the two pics. You did a lot more web browsing in safari and that eats battery similar to watching video (that's been my experience anyway).

    I can go through about 10% per hour by surfing the Internet.

    Id call that close, considering the first show was with 2 days and the first 1 day. Now if they were both the same amount of time I would say you have a problem.

    I did a restore that didn't properly finish on a replacement iPad and the battery was awful - restored again and the battery was fine.

    First picture is useless, you can't get 24 hours usage time from any phone. So that comparison is useless too.

    No but in the first picture there was some background usage which shouldn't count to real usage. I would say you had around 10-12 hours usage in your first screenshot.

    My iPhone 6 plus replacement over twice as bad battery life


    I see, fair enough.

    Well I wanna say it's improved slightly since altering some of the "always on" location services, and switching off Bluetooth.

    I would say that your battery life is perfectly normal now.
    I'm not doing any better than that on my 6+.

    My iPhone 6+ with 8.3 have pretty good STANDBY battery life (I think): at 100%, I left it for 8 hour overnight and the next morning it was still at 100%.

    But using it (no games, no video) over 7 hours yield worst battery life. Prior to 8.3 I will have about 50% left after 6 hours of normal usage. Now with the same usage but running 8.3, I am left with 35%.

    8.1.2, 8.1.3, 8.2 and 8.3 have had worse battery life than 8.1.1 and prior for me. My 6+ performs better than ever but the battery life doesn't astound me anymore. It's just 'good'.
