Mar 10, 2015 12:38 PM in response to Gator5000eby Lawrence Finch,No, I've never worked for Apple, but I have used Apple products and developed for Macs for over 20 years, and I've owned all iPhones since the first as well as an iPad 2. And I have experienced the same problem you have in past years (not recently, thankfully, but I've seen it with several earlier versions of iOS). Which is how I know the problem is not specifically iOS 8.x. For me the problem was always my MS Exchange account, and deleting it, rebooting, and adding it back usually fixed it. From reading other threads over the years Facebook popped out as a frequent problem also, and sometimes, more recently, iCloud. The other thing that almost always causes battery problems is jailbreaking the phone, but I doubt very much that you have done that (as there is no jailbreak for 8.1.3 that I have seen, and certainly none for 8.2).
Other possible culprits are the new iCloud Photo Library, Photo Stream, and Photo Sharing. And, there are over a million apps, and any of them could be an issue.

Mar 10, 2015 2:11 PM in response to Lawrence Finchby DaltonLima,I was reading about a guy in these forums that their problem was with the icloud keychain. And after desabling this feature in 5 others Apple products, suddenly the problem go away.IPHONE 6 Fast Battery Drain Ios 8.1.1
From jay Dedapper:"
This problem cropped up for me out of the blue three months into owning my iPhone 6. One day I came home with 70% battery and the next the battery was dead. I followed most of the suggestions here about resetting, etc. but my problem was different and worth a quick check if you still have this rapid battery drain problem.
In my case the issue was related to Keychain syncing and other devices using Keychain. If you don't have other devices syncing with Keychain read no further. If you do, open Activity Monitor on any Mac on which you are linked with your iCloud account. Click on the Memory tab and search for "secd" -- if that process is running and taking more than 100MB of memory kill it. You can do so from Activity Monitor or if you prefer, but typing this in Terminal:
launchctl stop com.apple.secd
launchctl start com.apple.secd
On any iOS devices that are linked to your iCloud account go into Settings > iCloud and turn off Keychain. Now do the same on your impacted iPhone.
I had two Macs on which secd was running out of control using 15GB+ of RAM. Killing those processes and then Keychain syncing on every other device connected to my iCloud account solved my problem.
The next day my iPhone came home with 85% battery full after a day at the office. Hope this helps."

Mar 10, 2015 2:21 PM in response to DaltonLimaby Lawrence Finch,That's good information, and it's certainly a possibility. Others have reported that signing out of iCloud on a Mac resolved the problem also, and this may be the underlying cause.
Thanks for finding this!

Mar 10, 2015 5:24 PM in response to Zahir Ahmadby crichton007,I had this issue and went into the Apple store for Genius support A LOT. I'm not convinced this is the solution but it was the only thing that was really changed on my device this last time and that seemed to fix the issue: Settings --> General --> Reset --> Reset Network Settings. You can even go as far as "Reset All Settings" but the former appears to have cured my battery woes.

Mar 10, 2015 7:23 PM in response to crichton007by ohhmy,My issue revolves solely around iCloud. I logged out today and went the day where my "Usage" accurately reflected usage and "Standby" reflected standby...I have 75% battery life 15 hours later (email is on manual) however, I had to log out of iCloud.
Just logged back into iCloud and walked away from the phone for 10 minutes and "Usage" and "Standby" both increased by 10 minutes. I went one by one shutting everything off inside iCloud and then one by one turning on, event with everything "off" my battery drained. For me, it is definitely a iCloud problem. I am not logged in on my Mac with iCloud either. I can't figure if there is something else hidden that I can't find.
Back to phones and the Apple Store.

But that's not a meaningful test. When you turn off iCloud, then turn it back on it must sync all of your iCloud services with the cloud image. So until that is finished it will use continuous energy. For this test to be meaningful you need to wait an hour, and then see if it is still using energy.

Mar 11, 2015 7:10 AM in response to Zahir Ahmadby Gator5000e,ohhmy, thanks for the post. Last night I decided to try logging out of iCloud completely and see what would happen. At around 7AM this morning, I took my phone off the charger, Three (3) hours later, I am still at 100% battery level. This is after a text message and 2 short phone calls. I haven't seen this type of battery life in quite a while. I will give it until noon to see where the battery level is at and if it's still good, I will try logging back into iCloud to see what happens. I will report back after I log back into iCloud and run the phone for a while.

Mar 11, 2015 7:40 AM in response to Gator5000eby jlfunder,I have tried most of the 'cures' proposed in this this discussion with little luck. ( These are huge time wasters and some of them make me feel like I am in a Monty Python skit). But when I finally succeeded in killing the iCloud connection completely (my what dire warnings Apple lays on you if you try to get out of the cloud!), the battery life markedly improved. I hate to lose 'find my phone' but there is no hope of finding it if it is dead. KILL THE CLOUD! KILL THE CLOUD! KILL THE CLOUD!
System: iphone 5 (replaced by apple 1 year ago) iOS 8.1.2 (restored from 8.1.3)- two active exchange accounts and a 60 installed apps. JF

Mar 11, 2015 12:48 PM in response to jlfunderby DaltonLima,What do you mean by: "killing the iCloud" ?
Did you just delete iCloud login from your iphone? Or is there a way to real delete the icloud account?

Mar 11, 2015 1:07 PM in response to DaltonLimaby Gator5000e,I'm not sure what jlfunder meant exactly, but I signed out of iCloud under the iCloud tab in settings. As of 4PM, my battery level shows 96%. It's been going since 7AM this morning. Of course, I have a bunch of stuff turned off as part of my trouble shooting efforts, and I haven't used the phone much today but with similar use before signing out of iCloud, the battery level would down to 25%.
Now I wonder if the fact that iTunes has been down for a good part of today has played a role in this, but I guess I will find out tomorrow once it comes back up.

Mar 11, 2015 1:57 PM in response to Lawrence Finchby ohhmy,I think its perfectly meaningful test. It's worked for me and look at the rest of the responses. I have 3 emails in my icloud account, I don't use the calendar, I don't sync contacts, I only log into iCloud to use "Find My iPhone", its the only thing active, the second I do that it kills my battery.
I love my Apple products as much as anybody have 3 ipads, 4 iphones, 2 imacs and 2 mac pros in the house. But give it a rest that the problem is something other than Apple. I appreciate that you want to help people but this entire thread is shooting down everyone's theory and we don't know how to use our phones.

Mar 11, 2015 6:57 PM in response to Gator5000eby jlfunder,OK. What I did was go to to settings/icloud and flip all the switches to "off". When I go there now I see that I am 'signed out' and need to sign in. That is how I killed the cloud. I did this about 10 days ago and the battery life has consistently been better ever since. Currently it has been 14 hr since I charged my phone and I have 56% battery. I have used google, maps, weather, message, notes, calendar, phone, audible, calculator, streaming radio, Facebook, and lots of email without worrying about battery. Previously this would have crashed my phone in about 7 hr. I tried all the other 'fixes' discussed in this stream and nothing helped much. Obviously this is not everybody's problem. Unfortunately it is, as they say, idiopathic. But for me, iCloud was eating my lunch and I think I need to get along without it. JF

Mar 12, 2015 6:59 AM in response to Zahir Ahmadby Gator5000e,I just want to report that yesterday, my first full day not logged in to iCloud, my battery went from 100% at 7AM to 83% at midnight. Can't complain about that. Of course, I had turned off the following settings before logging out of iCloud:
-Background app refresh off.
-Spotlight Search, I choose my searches.
-Lots of location services Off to reduce GPS use.
-Limit the number of apps that use Cellular data to only the ones I really need.
-Limit the apps using notifications - only have Calender, Messages, Phone and reminders enabled. .
-No need for automatic iTunes downloads.
-Turned off Location services for diagnostics & usage, Popular near me and routing & traffic in System services,
Of course I had made these changes before the iCloud log out and it's the logging out of iCloud that made the difference. Oh yeah, and I deleted Facebook and Twitter apps from the phone completely, but I don't think that made the difference as I had not even opened them or logged into them since I received the new phone on Saturday. but you never know. Now if I need to check FB, I go through Safari.

Mar 12, 2015 9:36 AM in response to bjmcmurryby RafaelZfromCC,Thank you. After many days of troubleshooting, resetting my iCloud password my battery drain went back to my normal rate of discharge.
