    Since the 8.1 update my iPhone 6 battery life has dramatically decreased. Is anyone else experiencing this issue? I was so pleased with the battery life with 8.0.2, not WiFi though.

    Give it a few days. It will settle after a few charge cycles.

    Can you provide a screenshots of your usage stats? I can compare them to mine for you.

    yup. Plenty of people reporting this myself included. That's why i'm rocking the 8.1 beta 1 because it's the only iOS version that's unaffected.

    My battery life has improved markedly since upgrading from 8.0.2. The first day was below average but that's to be expected, of course.

    I was one of those who reported this issue and have now updated my post because it worked itself out. Give it a day, then restart the phone. Mine now works as before, and has great battery life.

    Loved my battery life on 8.0.2 and I'm not so much loving it on 8.1. Wish they could figure out how to not affect battery life with updates. It gets ridiculous.

    In most cases the problems when switching to a new iOS version are (as I had with my switch from iOS6 > iOS7):

    - rogue app process (app not updated yet to iOS8/8.1) check Settings > General > Usage > Battery usage in percentage to determine which app is using much more battery although you haven't used it at all or much.

    - settings in e-mail receiving is changed
    - background app refresh (turn it off if you do not need it)
    - location services (look carefully which apps you want to use this feature)
    - notifications (look carefully which apps you want to use this feature)
    - Facebook app

    It's a good idea to DL the app 'Battery Doctor'. It will let you optimize your RAM, free up space and display statistics. Use the app when charging... it alerts when complete. Many more features. There is also a quick boost app available to free up memory on the fly. All FREE!

    That is good app, I use it too. Only thing what's bothers me after the cleanup of memory, catche and junk files, like 10 min later I open it again and it shows me that I am low on memory again, and my phone was idle. How it fill up the memory that fast again?
    I reduced background app refresh and location services to the minimum.

    I, too, am having horrible battery life on my iPhone 5S. I've never had battery issues, and even after a reset and iCloud backup, the phone is draining quickly with the phone not being used and sitting right next to the wifi router.

    I'm not a heavy user of my phone but I would say that my battery is now draining 50% quicker than 8.0.2.

    Hoping it just a software issue.

    Out of curiosity... The guy in the Verge video demoing Apple Pay said that you do not need to open passbook or anything for Apple Pay to work. You just put the device near the payment device. Does this mean that the NFC is actively seeking a connection at all times? Since Apple Pay was activated with 8.1, does this perhaps mean that this could be causing worse battery life now?

    My wife got 5 hours usage and 24 hours standby. With around 35% battery left. iPhone 5s. I have the usual optimizations going like limited background app refresh an other stuff.

    I recently bought three iPhones, all with IOS 7.1.2. But unfortunately when I was upgrading my wife's phone from the iTunes something happened and her phone was was put in a continuous loop. So, I had to put the phone in DFU mode and restored to the latest software. I was actually po'd because they were brand new, and I had NO say in the iOS version other than the latest. But all in all, my wife is actually pretty happy with iOS 8.1 and its new features ( and so am I). I will probably update the other two phones shortly, maybe this weekend.

    The 15 hours usage is from October 6th, the other usage is from today on an iphone 6+. Big difference. Freakin sucks. I dont know what the issue is. I have done restarts and all, no change. Screw you 8.1!

    i was experiencing the same thing with my iphone 6... i was having amazing battery life on the 8.0.2 then when i updated to 8.1, battery life got super worse! i gave it a couple of days to settle in and it was still pretty bad, so i took some advice and did a reset and set up as new, after that, its been wonderful! probably even better than what i was getting on 8.0.2

    ******** app that is pointless and for the gullible and foolish. I bet you also install the screen finger print readers and x-Ray apps too.

    No and No. You can read about how NFC works and some are even powerless like in a credit card. Anyway you do not need to open passbook or unlock the device. simply hold it near the POS terminal and it will open up asking for fingerprint and BAM done. It should not be a cause of excessive battery drain.

    I posted in other threads regarding battery but going from beta 2 to release I had a minor drain as well not bad but I could tell it was not like it used to be. After an iTunes restore all was great again. I let iTunes do it all, backup, restore firmware then restore my backup and back to awesome battery again. Pretty painless. Did have to add back in ApplePay card and add back wifi networks but over all it was worth it.

    For battery, more than likely, for space, it seems like a number of people would free up some decent amounts of space with it at times, so I don't know.

    The issue here seems like you spent more time on Facebook, which is well known as a lagging battery pig. T

    he battery life comes up as a topic with EVERY iOS update, and in my experience, the differences aren't huge when you're doing comparable things. The battery life with my 5s has always averaged around 5-6 hours, and with certain games, it might go down to 3 hours. If I have it in airplane mode or do other optimizations, then I've seen the battery life go over 9 hours.

    8.1 and Battery Usage

    ImageUploadedByTapatalk1414233299.720063.jpg

    Wow this is ridiculous at 3hrs before 8.1 the battery percentage would usually be about 40+. This is absolutely insane, this ****** update messed up my damn battery. And you see that, that was the last 24 hrs, but onced I fully charged my phone and left it charging for quite a while and removed it all I was doing was pandora and playing a game but I was on pandora for a good 2 min then mainly played my game. This is crazy....
