    Horrible. Drains much faster than 8.2 ever did. I've given it 24+ hours and done a Hard Reset twice and still is horrible. Anyone else seeing this happening?

    I'm not. I know that's not helpful, but no abnormal battery drain here.

    It may help if you quantify what you mean by faster. Are you going from 100% charge to 30% in a few hours? I always find that battery usage goes up after an update because we are using our phones more to test the effects of the update. At least this time Bluetooth was not automatically turned on after the 8.3 update which is a first for me.

    My 6+ went from full charge down to 39% in about 6 hours, which was highly unusual before 8.3. However, that's most likely because it keeps timing out trying to connect via Wi-Fi to my Exchange profile at work. Good chance that it's unrelated to whatever could be causing your battery problems.

    Major software updates usually clear out the information in the software related to the calibration of the battery and all of that jazz. Usually letting the battery run out and charging it up to 100% once without unplugging after a major software update will normal it out. Also, make sure no settings that you didn't have on before were changed.

    Things to check: Privacy (location services), Background App Refresh, Mail Server Settings (Fetch, Push, etc.). Try a Reset All Settings if your battery runtime is abnormally short as there may be a process hanging in the background.

    If it's worth anything to you my battery life is roughly the same if not better with 8.3 on my iPhone 6 64GB.

    Usage time is usage time, whether achieved over 6 hours or 24.

    Mine actually seems better on 8.3?

    3pm local time here at the moment, been off charge since 7:30am and sitting at 84% still. WiFi/Bluetooth, push, all movements (background perspective display) on, about 25% brightness. Using standard stuff like SMS, Facebook/Messenger, Instagram, Snapchat throughout the day etc... *shrugs* seems good to me!

    Mine was the best on 8.2. With 8.3 it's back to 8.0,8.1 levels. Seems like Apple has 2 different teams working on different point updates. The teams must have forgotten to code share with each other.

    I've only been through one charge since I went to 8.3 and it's better than 8.2 for me. Time will tell, I've never had any issues with my 6 on iOS 8 it's always been much better than my 5S was on iOS 7~.

    Lasted about 4.5 hours on my 5S. I spent the entire battery life on setting up my replaced 5S since it wouldn't restore from back-up :mad:. Even then, I thought the battery drained a lot quicker than I hoped. However, I did a lot of iTunes restores to make the back-up restore work... Hopefully this didn't damage the battery.

    Battery life seems normal to be if not better.

    Too early to say for me as I'm still on my first charge since installing 8.3
    My initial thoughts are that it's no better or worse. Just the same.

    I also noticed this problem. The weird thing is the battery life was really good on my 6 with 8.3 beta, but after updating to the public release it got noticeably worse. I guess I'll wait a couple more day to see if it fixes itself before restoring.

    I only ever really get 10 hours out of my 6+ anyway, so your stats would be perfectly normal for me. My battery life hasn't been as good as it was out of the box ever since 8.1.2

    Worse for me!

    Since Wednesday I've had to charge my 5S by 2:00pm each day. On 8.2, I could go most of the day on moderate use.

    Seems better on my 6 Plus than 8.2. Still not as good as 8.0.3, though.

    8.1.2 and prior I used to hit 12 hours usage consistently on my 6+. There were many days I even hit 14 hours. Now since updating to 8.2/3 it's a struggle to reach 9 or 10 hours. I do a full restore and setup as new each update that's come out. 8.3 has been better than 8.2 though only slightly.

    I voiced this a while back but everybody said their battery life had been unaffected from day one. I fully agree with you.

    6 Plus

    For my 6 Plus battery life is fantastic. Right now I have:

    Screen Time 7 hrs 51 minutes
    Standby 1 day 4 hours

    43% left.

    Love it.
