Iphone 5s battery drains fast after ios 7.1 update.

Thing is 7.1 patched alot of security bugs, so you need the update. My 5s seems to be getting about the same as before, first few days it went down faster but with light use i got three days out of it and 6 hours usage. Here is the list of security fixes http://support.apple.com/kb/HT6162

Do a clean installation. This OTA update is just a little patch compared to the 1.X gb update, there must be something. It is convinient, but there is nothing better than a clean installation. It is a pain because you have to back up your files and delete everything, but it is the only way to have good battery life. I was being lazy until I decided to do it and now my iphone 5 running ios 7.1 has better battery life than before, it was also getting very hot. As far as I was told by an Apple Store tech if you restore from a backup make sure you use the one from iCloud instead.

I am updating here based on my last post.

Since I peformed the reset > reset all to return the 5s to its defaults and and then restored from my iTunes backup on my PC, this appears to have solved my 5s battery draining 1% every 10 mins which surfaced when I did an OTA upgrade of 7.06 -> 7.1 Proceeding forward, I have only turned back certain apps so I cannot be sure which if all / any are the culprits or if it is like I suggested, FW best practice is reset system to defaults.. etc.. YMMV. Cheers.

After trying all of the suggestions, letting battery drain, etc..etc..nothing had resolved this issue for me. Spoke to Apple yesterday who wants to replace my phone but is this going to resolve my issue?

My Iphone 4S battery is draining 2x faster after update. This is obviously an issue. Apple, when will the fix be available? Btw, I shut off my cellular connection and it still is draining 2x faster.

OK here goes once more. Things to do to get battery life as good or better than 7.0.x. 3 iPhone 5s devices are getting better battery life than before.

1. Hard reset hold both buttons until Apple logo appears.

2. Restore from an iTunes sync and backup. This made a difference for me, battery life got much better.

3. Limit push notifications to those you really need.

4. Limit location services to those you really need, and watch to see if the indicator comes up.

5. Get the app System Activity Monitor to look for a runaway process that is using a lot of CPU.

6. Suggestion by others to reset all settings.

7. Suggestion by others that iCloud may be involved, and to try to turn off some iCloud settings.

8. Limit or turn off 'background app refresh'.

9. Add apps back in carefully to identify an offending app that is causing CPU or network activity that kills battery life.

If you haven't tried every single one of these, please do not post that battery life is terrible.

I did everything, reset, hard reset, reset phone to brand new. Battery drainage is still the same. Apple jacked up something on the iOS 7.1 Software update????

Prob is better now. Seem back to pre update battery performance.

@DriftMy5.0GT did you do everything mentioned by Nathan in his message?

In my case it was a bug with an app that caused the battery drain. I also noticed that the use and stand-by time were exactly the same which is ofcourse not correct. This was all caused by this app which was using GPS tracking all the time. Unfortunately an app such as System Activity Monitor did not indicate that in my case but someone posted this solution on a Dutch forum that the previous version of the app 'Scoupy' had a bug and caused this battery drain.

- Is you use/stand-by time exactly the same?

- Also make sure that e-mail is fetched (e.g. every hour) or set to manual instead of pushed.

- Do you have a good carrier reception? Have you tried to manual set your carrier within your iPhone instead of the 'automatic'?

- Have you checked if the timezone is set to manual instead of automatic and see if this makes a difference in battery use?

If you haven't tried every single one of these, please do not post that battery life is terrible.

The OTA update needs 1.9 GB room on your iPhone, its a compressed file, its essentially the same update. Many have found resetting all settings (not wiping your iPhone) has helped. Sometimes just a hard reset helps. Make sure you have no apps running in the background and always have the phone plugged in during OTA updates and it should not cause any issues. Of course there always going to be exceptions. Also the way background App Refresh has changed in 7.1 before if the app using it was closed by swiping it up when double clicking the home button that closed the app refresh, in 7.1 the app will always refresh no matter what now, as it should do.

How do you clear data usage & history from an iPhone??

did everything you stated....still the same..pos iPhone...may have to buy a Samsung Galaxy 5S????

Replacement iPhone 5S received yesterday-tried everything. Battery down to 20% already.

Just off the phone with Apple who confirms that this is a known issue but not happening to everyone's phone? My choices given to me were to continue to get a replacement phone until it is resolved or wait until a software update comes out. How could this be? I asked if the cell phone carriers were aware and the person did not know. What kind of service is this Apple?

Well, at least they admit to knowing there's a problem, LOL. I swear, since Steve Jobs has passed, they add one update after another, ALL of which mess up my phone and/or iPad and/or iTunes...
