iOS 8.1.3 drains battery on iPhone 5S much faster

No I have no battery issue with my 5S on ios 8.1.3

There is no Apple here in this user to user technical forum, so no Apple won't see this.

I'm sure that several people have noticed this besides me. Since downloading and installing iOS 8.1.3 on my iPhone 5S, my battery life is much shorter.

Yes, I know about closing open apps, turning off Bluetooth, etc. All done before the new iOS. I'm just saying that it's noticeably worse now with everything else being the same. Hopefully, Apple is aware of this and resolves it in the next update.

Please chime in if you're experiencing the same issue, so that Apple can see that it's widespread.

1. This is not an appropriate place to provide feedback to Apple. Go to www.apple.com/feedback or contact Apple directly.

2. This forum is not for conducting polls, as you are attempting to do. Please review the Terms of Use of this forum. [https://discussions.apple.com/terms-and-conditions!input.jspa]

3. None of the devices I own or manage (totals up to about a hundred or so) running iOS 8.1.3 have experienced any decrease in battery life. Your perception is flawed and your conclusions based upon insufficient evidence.

Test your battery life without bias:

Make a backup. Restore as new. Test the issue again. Here's a way to test your battery 'issue' without any bias:

• First, charge up the device to 100%. To enable the percentage indicator, go to Settings > General > Usage, and turn on Battery Percentage.

• Once the device is charged to 100%, make sure to close out all Apps that are running on the device. In iOS 7/8, you close out running apps by double-tapping the Home Button, and then swiping your finger up across the preview screen of each app to move it off the top of the screen.

• Then, turn off Wi-Fi, Bluetooth and cellular data. Settings > Wi-Fi > Wi-Fi: OFF, Settings > Bluetooth > Bluetooth: OFF, & Settings > Cellular > Cellular Data: OFF. This will not prevent you from receiving any phone calls.

• Go back to the Home Screen, and take a screenshot. Press both the Sleep/Wake button and the Home button together briefly, and you will see the screen flash white for a split-second, and an image will be saved to your Photo App Camera Roll.

• Disconnect the iPhone from the charger, and lock the screen so it is dark.

• Let the iPhone sit in this ‘standby state’ for as long as possible, preferably overnight.

• In the morning, unlock the screen, and then take a screenshot of the Home Screen again.

These two screenshots will help to document how long the device was in standby mode, and how much battery percentage was used. Then post your results.

II've got 2 iPhone 5s one with 8.1.2 and the other with 8.1.3 both drain battery fast and heat up. even after a complete restore in DFO mode with nothing on the phone. the phones are not sending any error codes either.

I have been facing the same issue as well... Even after a restore, things dont improve !!! Hopefully Apple comes out with a new update soon !

It seems that something is useing the ram. If install a memory aniliser app I've only got 4% free memory (ram) there is nothing on the phone Running or intalled

Right.

And that's why I see so many threads on this forum posting about the very same thing. With you attempting to negate every one of them.

You'd be surprised how many people jump to a faulty conclusion based upon inaccurate or coincidental evidence, especially those that lack a fundamental understanding of how the technology works.

Use the articles & procedure I provided. If the symptoms remain, then it is a hardware problem, not a software problem. If it was a software problem, then all devices running the same iOS would have the same symptoms. This is clearly not the case.

Hi Ira,

You are not the only one, I am experiencing the same issue. Phone gets warm and battery drain and I have done everything still no change. It is in fact a software issue. Hopefully next weeks update will fix this.

No, it in fact, is not. If it was an iOS issue, then all identical devices running the same iOS version would have the same symptom.

Use the procedure I posted. If the issue remains after the properly using my procedure, it is a hardware issue.

That's funny went the apple store and they scanned my phone told me hardware is good and battery is good.

I have done all the things listed and still nothing fixed the problem. So I replaced the battery in both the iPhone 5s that I have, still no different. So I replaced the charge ports= no change. I've replaced or disconnected as many hardware items as I could still no change in either phone. If it were hardware it should send an error code at least when I restore the iPhones but it doesn't.

Then it is likely some form of setting or user data. Erase your device, set it up as new, and test it again. If the issue persists, then it is hardware, because at that point, none of your settings or user data are on the device.

The diagnostics at the Apple store are of a high quality, but are not the final word. Just like the 'Check Engine' light on your care can be off, but there can still be an engine problem.

Apple isnt the final word? If my car has issues and there is no engine light on it can still be diagnosed and fixed. Apple doesn't even know what the issue is they built the device. Who Or what is the final word - go buy another??

I have set it as new still has issues.
