You can follow these steps to save battery.
1. Turn on Auto-Brightness - The iPhone has an ambient light sensor that adjusts the brightness of the screen based on the light around it (darker in dark places, brighter when there's more ambient light) to both save battery and make it easier to see. Turn Auto-Brightness on and you’ll save battery because your screen will need to use less power in dark places.
Find it in the Settings app -> Brightness & Wallpaper -> Auto-Brightness On
2. Reduce Screen Brightness -the brighter the default setting for the screen, the more battery it requires. Keep the screen dimmer to conserve more of your battery.
Find it in Settings -> Brightness & Wallpaper
3. Stop Motion (iOS 7) -It's really cool, but it also drains battery. You may want to leave it on to enjoy the effect, but if not, turn it off this way:
Settings -> General -> Accessibility -> Reduce Motion -> move slider to green/on
4. Turn Bluetooth Off- Turn off Bluetooth except when you’re using it to squeeze more juice from your battery.
Find it in Settings -> Bluetooth -> Move Slider to Off
5. Turn Off Location Services -
This allows your phone to know where you are and give you exact driving directions, give that information to apps that help you find restaurants, and more. But, like any service that sends data over a network, it needs battery power to work. If you’re not using Location Services, and don’t plan to right away, turn them off and save some power.
Find it in Settings -> Privacy -> Location Services -> Slide to Off
6. Don't Automatically Update Apps (iOS 7)-
If you've got iOS 7, you can forget needing to update your apps by hand. There's now a feature that automatically updates them for you when new versions are released. Convenient, but also a drain on your battery. To only update apps when you want to, and thus manage your battery better:
Settings -> iTunes & App Store -> Updates -> move slider to off/white
7. Auto-Lock Sooner -
You can set your iPhone to automatically go to sleep – a feature known as Auto-Lock - after a certain amount of time. The sooner it sleeps, the less power is used to run the screen or other services. Try setting Auto-Lock to 1 or 2 minutes.
Find it in Settings -> General -> Auto-Lock -> Tap your Preference
Few more things that would consume battery even when not is use are the applications that run in background.
Follow the below steps to quit all running applications.
1) Double tap on the home button on the iPhone ( this will display all apps that are running in the back ground).
2) Just click on the tiny red X to quit application ( if iPhone is running on iOS 6 and below) else just swipe yhour finger over the running app upwards to quit ( if running on iOS7).

IP4S Battery Drain Was 8% hour. Restored As NEW PHONE Via iTunes Battery Drain Now 1% per hour!

RE: iPhone 4S rapid battery drain out-of-the-box.
I had been experiencing a battery drain of 8% per hour.
Apple's software update did not make it better!
I then restored my iPhone 4S as a NEW phone and now my battery is draining at 1% per hour with all settings at maximum for battery drain.
Apple could have done more to make millions of customers happier customers.

Thanks for sharing. Restoring the phone first from backup then as new is one of the standard troubleshooting steps outlined in the User Guide. Too bad more people like you don't realize this.

I have had my iPhone about 1 1/2 years...with no problems. About 2 days ago my battery drained within an hour, I plugged it in to charge and it heated up so hot the temperature warning popped up on the screen. The phone will not hold a charge now.

I have had my iPhone 4 for about 1 1/2 years, with no problems. A couple days ago the battery drained in about an hour, I plugged it in to charge and it was not charging. After a few hours a message popped up on the screen about the temperature being too hot...the phone was very hot when I picked it up. The battery will not hold a charge and it heats up every time I plug it in. Suggestions???

Make an appointment at the genius bar. An out of warranty replacement is $149. It sounds like it may have gotten wet.

Hi!
I have an iPad 3,3 GSM. I didn't update it since iOS 5.1.1. iPad works almost a week for me. And updated it to 7.1 at last Friday.
After update my battery drains notable fast. ~10-12% overnight(~8h) in standby mode. I've tried to turn off parallax, all location services and background apps. But nothing's changed.
So I''ve found that in usage section I ve almost the same values of usage and standby time. And I realized that one thing that drains my battery is "Find my ipad" service!!! I turned off it and my ipad works as with iOS 5.1.1:
2% overnight max!! And now it's drained only 14% after 4h20m of usage with parallax turned on! (yes i've only surfed web and read a book but nevertheless)
So it's your choice what to prefer - be sure that your ipad either protected from stealing or long battery life!

I just got my apple iphone 5s and the battery drains after a hour or so wether im on the phone or not how can i change this

please help battery draining sofast I just got the phone month ago

If you have Bluetooth turned on, turn it off. If I forget and leave Bluetooth on, it drains my battery about twice as fast as when it is off.
Turn off Background App Refresh in Settings>General
Turn off any location services that you do not need on under Settings>Privacy>Location Services (I have Location Services turned on, but in the Apps list below the button, I have very few turned on - Compass, Maps, Google Earth, Google Maps, Siri, Starbucks, and Weather).
Cheers,

IPad iOS 6.1.2 update causing excessive battery drain

I have noticed in other discussions that a number of iPhone users have experienced excessive battery drain after updating to iOS 6.1.2.
I am now experiencing this problem in a big way after updating to iOS 6.1.2 on an iPad 3.   Prior to this update, my battery life was very good, dropping to only 70% to 80% at the end of a typical day of use.
After the update, which was said to be to fix a previious Mail Exchange battery drain issue (one that I was not experiencing), my battery was dropping to 30% after a few hours. It was literally like holding a bucket with a hole in the bottom and watching the water drain out.
I noticed that my Usage time and Standby time were identical, even though the ipad had been in sleep mode much of the time.   This indicates to me that something about this patch is causing the iPad not to actually sleep when in sleep mode.
The iPhone discussion forums point to a number of possible fixes, including uninstalling all emails and re-installing them all the way to a total erasure and reinstalation of everything. This worked for some, but not for all victims of this problem.
Until Apple recognizes this problem and sends out another update, one less painful solution that worked for me was to change all of my email accounts from Push to Fetch every 15 minutes.   This has stopped the problem for me, for now. so I wanted to share this in case anyone else is experiencing similar problems.
If other community members have discovered other short term or long term fixes then please do post here.
Apple, I await an update that will allow me to restore Push functionality, or instructions on what steps will work to properly restore full functionality (what to remove and reinstall etc).

Just to confirm that I have the same problem. I updated to iOS6.1.2 on Friday 1 March 2013, I have an iPad2. And Saturday morning my iPad was 0% after having nodded off on a 78% full battery. This has NEVER happened before, and has become a daily occurrence. I have now amended my Mail to fetch and hope it works.

Iphone 4S resets itself every few min - the battery drains in an hr.

My iphone 4S is resetting every few minutes as a result the battery drains in an hour.
By resetting I mean, the lock screen would show up, then the apple sign would come up like when you start your iphone, searches for the network etc. This happens every few minute even when the phone is on standby or when I am using it. If I am on the call, then the call gets disconnected because the phone is resetting.
The usage always shows "-" for both Usage and Standby with the message that the usage time will be shown after iphone is fully charged.
This started only a month ago when my phone was not on the latest os version. But now it is on the latest but the problem never did go away. It never fell out of my hand or fall into water and is barely a year old (just 10/15 days over the warranty period).
Please help!

And I should mention that I took the foll steps so far:
1. Let the battery drain out completely and charge it overnight
2. Backed the phone, then reset the phone and restored from backup.
3. Took it to the apple store and they did a different kind of restore but no luck
The only thing left for me to try to is to reset it to factory setting unless some one can suggest some other way.

IPd 3G battery drains quickly

Dear all, I used to charge and sync my iPod 3G with Mac with firewire. Recently, I found that if I plug with the Mac with Usb alone. The battery drains within one minute. To confirm the problem, I fully charged it and play song, after an hour, there were 2/3 battery left, then I plug it with Mac with USB and the battery drained in seconds. Could anyone tell if it is normal?

Battery drains no matter what I do

Hello there,
I got my iphone replaced because after 1 year of perfect service and the best of battery performance, my iphone started draining battery.
They couldn't find an answer so they replaced it.
What I got is an iphone consuming 25% an an hour no matter if in stand by or in use.
I tried every single restriction I could, including starting it as new.
Right now I don't even have my contacts in it and it's draining 1% every 3-4 minutes.
At they gwnius they've told me it takes a week for the new battery to asset.
It's been 4 days and zero improvements.
My old 4s used to last about 10 hours with a very heavy use.
This one won't make it on stand by mode for 5 hours.
I am very disappointed

IPhone wifi bug and battery drain in iOS 8.1

I have an iPhone 5s 32GB and updated it to iOS 8.1
the wifi bug is still there and my battery drains within 4 hours of normal use(no gaming)
the option to chose 2G/3G isnt there too
any help ?
Please fix these bugs soon

Power cycle the battery, let it fully drain to where your phone shuts off and then fully charge it without using it.
As for mail if you have it set to push try using manually fetch - the server will only check for emails when you open the mail app, instead of pushing the mail to your phone when you receive one.

[BUG] iOS 6 - BATTERY DRAIN : SIRI Raise to Speak/Proximity Sensor Always On/Flashing When Screen Active

Bug: Raise to Speak sensor for Siri remains on whenever the screen is active - regardless of Siri Raise to Speak Setting (enabled or disabled).
After updating to iOS 6 (via iTunes - not OTA), I noticed that my battery was taking quite a bit of a hit. Granted I was checking out the new features but aside from a very short call, nothing major in the way of activity.
I had also noticed that Siri sounded quite a bit different with iOS 6 (10A403) than with 5.1.1 (9B206). Not only did the Siri Voice change but also the responses vary between the two iOS versions.
Example: What is the weather like in Alaska?
iOS 5.1.1 response:
Here's the forecast for Juneau, Alaska through Monday
iOS 6.0 response:
Here's the weather for Juneau, AK through Monday (note: Siri does not say "Alaska", instead Siri says 'A-Kay'
With iOS 6, Siri sounds more robotic. After looking at speech rate settings and comparing between the two versions, I could find nothing different. I decided to post a video and this is where the Siri bug became interesting and tied into the battery drain with iOS 6.
Remember with 5.0.1 we saw a hit on battery drain and one of the fixes was a fix to the proximity sensor (http://hottipscentral.com/could-siri-be-hurting-iphone-4s-battery-this-little-li ght-might-mean-something/). Well, it appears this bug is back in iOS 6. When I went to do the video, I noticed that my 4s had a flashing light near the earpiece. It remained on continuously. The only time it would stop flashing was when the phone was locked and the screen inactive. As soon as I hit the lock button to bring the phone out of lock, the sensor would begin to flash again.
Give it a shot, hold up your iPhone to a webcam and see if your result is the same.
Submitting this to Apple via the feedback form. Please do the same if you are seeing the same behavior.
http://www.apple.com/feedback/iphone.html

I dont believe so Amy. Phone has not sustained any damaging drops nor any liquid spills. Was not an issue before but I figured I'd post as I believe this is a definite bug. I neglected to mention that I have my wife's 4s (5.0.1 build) which I am using as a comparison.
Based on the issues folks are reporting with the ambient light sensor, its either the proximity or the ambient light sensor causing the drain. I've turned auto brightness AND raise to speak both off and the sensor continues to flash as I described in my opening post.
If others can confirm, this will definitely need to be looked at by Apple and fixed.
I just found this - same behavior (posted 7/24/2012 on another forum - source link below).
Hi folks, remember the proximity sensor (always on bug) I reported here in iOS 6 Beta 1 bugs/feedback thread? It continues to happen in beta 3, I reported to Apple and the answer I got from them is that it behaves how it's intended to do
Thing is, when you turn Raise To Speak feature off, and use your webcam (no IR filter) to verify if it turned infrared proximity sensor off, results that it didn't. Since iOS 5 this bug has been present, power cycling, or doing a soft reset solves this issue but this solution does not apply in iOS 6. Don't have an idea on how hard it is on battery draining, but it makes no sense that this sensor stays on forever even when you turn this feature off. Unless it has to do with constantly display brightness adjust feature that we have noticed came with iOS 6 version. Doing some test of this feature (some of you commented about a brightness bug in earlier posts) I noticed that ambient light variations make that display brightness adjust accordingly to brighter or darker ambiences. Previous to iOS 6, the sensor samples the ambient light, and adjusts the brightness; it does this only once--each time you unlock the phone after waking it. Now in iOS 6 you can easily watch how brightness slider adjusts itself when display senses light variations. If you open Passbook app it raises brightness to full (it is supposed to act this way for easy reading of barcodes) but getting out of Passbook app makes that brightness readjusts itself responding to actual ambient light intensity (this adjusting task occurs slowly until brightness slider stops to right level).
I've checked and ambient light sensor and proximity sensor are separate and work differently but if Apple says that an always on proximity sensor in this iOS version is behaving how it is intended to do; all that I could think of is that it has to do with ambient light "sensing"??
