Is anyone else experiencing battery life issues due to iOS 8.1.3?

I'm having this drainage problem too.
iphone 5s, already trying restore a zillion different ways, turning off every little function and still no results.
Even try some beta version (but I can't say more, because Apple will delete my posts if I say something about beta versions in this forum)I

I'm out of ideas... 😢

Here are some ideas: http://www.overthought.org/blog/2014/the-ultimate-guide-to-solving-ios-battery-d rain

Thanks LF! But i've got through all these steps (without going to an Apple Store, because it's a used iPhone and here in Brazil we don't have App Stores, except in Rio de Janeiro and soon Sao Paulo.

The odd thing, is that the drainage occur even when restore the iphone as a new device and in airplane mode.

Restore as a New phone. Do not log in to iCloud. Do not add any email accounts. Do not install any apps. If it still drains then it probably is the battery.

If it does not drain under these circumstances then log in to iCloud. Wait several hours, because iCloud needs to sync, and that uses battery power. Then charge it and check the battery life again. continue adding back features until you find the one that drains the battery. Facebook is high on the list of suspects.

Nice tip LF! I'll try that and report tomorrow! I guess that every time that I restore as new I log in my account. I'll do as you say.

Even restored as new, (without log in any account, without any app, practically all functions turned off - and in airplane mode!!!) the battery drains around 12% per hour in standby.

I've do this at 8.1.3 - 8.2beta5 and even in 8.3beta2. Same result.

I read about a bunch of people in same spot as me that even replacing the battery the problem stills. I guess the problem is something with the iOS 8.

The "Home & Lock Screen" is responsible for 75% of the consumption (according to the ios). And 15% goes to "Settings"

The problem is NOT something with iOS 8. Battery issues can and do (did) happen with any version of iOS going all the way back to 1.0.0.

Note also that the consumption figures are PERCENTAGES, not actual energy use. By definition they must add up to 100%. So if one item is 75% that means that other things are not using much energy. It says NOTHING about how much actual energy Home and Lock Screen are using. This is normally covered in 4th grade math. I hope you haven't forgotten something that basic.

The Genius Bar diagnostics showed that my battery was in perfect health, but several system processes were continuously crashing. Eventually, the Genius Bar replaced my phone since a clean install didn't solve the problem (they said "might be the logic board"). Lo and behold, the BRAND NEW PHONE with a clean install does the same thing. Sorry, but the most likely explanation is that iOS 8, or perhaps 8.1.3 specifically, is the problem.

This is not a battery issue and it's not something that can be solved by turning off auto-brightness or background app refresh...the drainage is simply too severe to be accounted for by these types of normal processes and still occurs even when these "fixes" are tried. My phone (both my old one and now the replacement), in airplane mode and sitting on my desk with the screen turned off, is now losing ~5-8% battery per hour, with standby and usage time showing almost identical (even without actually using the phone). Just a few weeks ago, my phone would lose maybe 1-2% overnight, now it loses ~50% overnight. Again, this is happening even after getting a completely new phone.

Given that this didn't start happening until 8.1.3 (at least for me), the obvious explanation is that it's a software problem.

Well...Certainly can be a battery issue. Batteries loose their capability of retaining the same amount of charge over time. But it's strange when this happen over night and in huge steps. (12% per hour drainage its unacceptable - in the conditions that we set previously - airplane, no accounts, all turned off). This is by far, not usual for a one year iphone 5s.

But let's see the facts:

*There are many reports in this same forum saying that the battery drainage ramped up just after installing iOS 8.1.x (iphones 5s, 6 and 6+).

*Some people don't solve this problem even after replacing their batteries.

Draw your conclusions.

ps. the Percentages that I report it's only to illustrate that there is no App draining battery besides the default ones (at least not in the iOS's report system). (and I report only the 2 major values, because I don't wanna bother you with the minor ones)
And by my understanding, that Percentages refers only to the "Used Charge" till that moment.

While we are seeing "facts" - My iPhone 6 on 8.1.3 goes 3 days on a charge. The best I ever did with any other iPhone and any other iOS version was a day if I was lucky. If it was an iOS 8 problem I wouldn't see this significant improvement in battery life.

Another "fact" - It isn't affecting a lot of phones. If it was you would see thousands of posts about it. Like this thread:

Almost 13,000 posts and 2 1/2 million views before it was locked. And you will notice that it was for iOS 4 on a 4S. For background, this was for an actual bug in the MS Exchange driver that only affected phones where an Exchange calendar repeating event entry was edited. It affected less than 1% of users, at a time when there were under 100 million users. Today there are 500 million. The current thread with 68 posts, many multiple from the same users, is not an indication of a widespread problem. I'm not saying there is no problem, but focusing on iOS as the culprit is not going to get you anywhere in trying to solve it, and waiting for Apple to fix it isn't going to be fruitful either.

It is not a hardware problem, and not an iOS problem. It is, as it has been for 7 years, an app, data sync or data corruption problem. It isn't new. Do this:

Restore the phone using iTunes and set it up as NEW. Do not reload a backup. Do not create any email accounts. Do not log in to iCloud. Do not log in to ITunes & App Stores, Podcasts, iMessages, Facetime or Game Center. Do not install any apps. Do not enable Photo Stream or Photo Library. ESPECIALLY do not install an app that monitors the system usage. Most of them use huge amounts of energy. Then check your usage for a few hours. If it has used more that a couple of percent you may actually have a battery or hardware problem. But it probably won't.

Next, log in to iCloud, but leave all of the switches off, and check usage again. then turn them on one at a time. But wait at least 15 minutes after turning on a switch, because it WILL use a lot of battery when first turned on until it finishes syncing. You may find that one of your iCloud features is the culprit. This usually means that there's an app on another device that is frequently updating that feature.

If you have an MS Exchange account do the same thing with it.

Proceed adding apps and checking, remembering to give each app time to sync. You may find that the problem is gone, even after all apps have been reinstalled. In this case the problem was corrupt data in one or more apps. If not, you will be able to identify the app at fault.

Did you log in to iCloud or an MS Exchange account? Keeping the phone in airplane mode can actually increase battery consumption as apps keep trying to communicate and fail.

I didn't log in to any service. Just shut down every feature that I can see in the Settings. Airplane mode consumption make sense and now I'm gonna try with only with wifi on. No apps besides the original ones. No Email Account either.

I agree with you that facing the millions of iphones in the market, this problems related here are a inexpressive amount of the user base.
I also agree that this problems seems probably like software problems. When I say "iOS bug", i meant for example some icloud service that are stucked trying to sync, or some other app or service running.

For last I want to say that I appreciate the time and effort that you put in here to help all of us!
