IPhone 4s with iOS 7.0.2 Battery Drains FAST!

My iPhone 4s with iOS 7.0.2 the battery drains tremendously fast! This morning it was 100% charged then just by surfing facebook and flipboard with 3G, it became 7% in the noon. I hope Apple can solve this problem! I'm very upset right now

I've pretty much proved to myself that this is a bug in 7.0.2. Since my post a few days ago I have:
Done a full restore of my iPhone with 7.0.2 - problem still persisted - draining battery at approx 23%/hour with no use, and with all the battery saving tips applied (no push notifications, no background updating etc).
Restored iPhone with 7.0 - battery drain dropped to approx 5%/hour with no use and battery saving tips applied. With push notifications & background updating turned back on, battery drain increased to approx 12%/hour which is high, but still significantly better than 7.0.2.
I would recomend everyone who is having this problem with 7.0.2 to lodge a bug report with Apple - www.apple.com/feedback - hopefully if enough of us lodge the bug report, Apple will listen and release an update.
As for downgrading, unfortunately we cannot downgrade to 6.x anymore, but you can downgrade to 7.0. It is a matter of downloading the appropriate firmware. Firmware's are available here - http://www.icj.me/ios - although that site lists 6.x, they will no longer work, so get the 7.0. That site redirects you to Apple's server for the appropriate ROM, so they are legitimate. Before you install it, you have to turn "Find My iPhone" off by going to Settings | Privacy | Location Services | Find iPhone. The installation seems to turn it back on when done, but you should probably check. Once the firmware has downloaded, you can install it on your device by going to iTunes, and holding down the option key while clicking Restore. This is on Mac - on Windows I assume you would press Alt (but if that doesn't work, try Ctl or Shift). If you have pressed the right button on your keyboard, a file browser window will appear, allowing you to choose the firmware that you just downloaded.
Once installation is complete, iTunes will tell you that there is an update available for your iPhone, just click "Later" everytime the warning appears.

IPhone 5S with iOS 8.0.2 battery draining rapidly

I have an iPhone 5S with 8.0.2 recently installed on it. Normally, I can go a whole day and have the battery around 50 - 60% when I put it back to charge it at night. However, lately, the battery has been draining so fast that it doesn't last an entire day anymore. My usage has not changed. If I look up the battery drainage for the last 4 hours, the major players are Mail (28%), Home & Lock Screen (17%), and Facebook (13%). For the last 4 days, it has been Mail (41%), Home & Lock Screen (15%), and Safari and Facebook (11% each).
I had this problem with iOS 7.1.2, and I took it in to the Apple store and was instructed to delete and install Facebook again. I did this, and it didn't help. I then restored the phone and re-installed the back up. That worked until about a week after I installed iOS 8. I tried upgrading to 8.0.2, and the drain was faster if it changed at all. I tried restoring from the backup again, and this time it didn't help. My last option would be to restore as a new phone, but I'd like to avoid this if possible. It would take more time than I really want to spend on it.
My background refresh apps are limited to just a few. I also have the Mail program set not to notify me unless I get a message from a certain account or a VIP. I also limit what can use location services. Also, since mail was consuming the battery, I tried to decrease the frequency of retrieval, and even changed it to manual. Neither option helped the battery life.
I wonder if something is wrong in the OS that is causing this. Does anyone have an idea?

Hey David Ancell,
Thanks for the question, and great troubleshooting so far. You have already taken all of the most applicable steps: optimizing your settings, viewing which apps are using energy, and configuring your notifications. Because restoring the back up of your iPhone may restore the culprit causing these symptoms, restoring as new is your best option for isolation purposes:
iOS: How to back up your data and set up your device as a new device
http://support.apple.com/kb/HT4137
After erasing and setting up as a new device, your device is now in a factory configuration. Test to determine if erasing and setting up as a new device resolved the issue. Content on the device may have caused unexpected behavior.
If the issue is still present, you may want to contact Apple Support.

IPad mini with retina very slow and battery drains fast

my ipad mini 2 is only ten months old. After getting the iOS 8 currently on ios8.0.2, wifi internet speed is only 25% of the normal speed (compared to what my imac tested), battery drains 1% every 3 minutes or so. All of these after I restored it to factory setting per Apple support suggestion. is there any fix for this soon? why is the issue only affecting some but not all users? Is there anything I can do for my ipad? I have only been using it lighty (have installed like less than ten app's) but this is still very frustrating.

If You Think iOS 7 Feels Slow Here’s How to Speed It Up
http://osxdaily.com/2013/09/23/ios-7-slow-speed-it-up/
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

My iPhone 5 with iOS 6.1.3 keeps crashing at 45%!when my iPhone nears 45% from a full charge it suddenly says the phone is 20% then 10% then 1% and then it goes dead.when I plug in the charger instead of waitin a few minutes for it to turn on,it instantly turns on and says the battery is 45%!this is OK at home where I can keep the charger plugged in but what about when im on the go?PLEASE HELP!!!

This is most likely faulty battery. Make Genius reservation or set up service and take or send to Apple for resolution under Warranty.

My iphone 5, with iOS 7.0.2, is heating and consuming the battery very fast when 3G is on, even when I'm not using it. Any solution?

iOS 7 has many multiple tasks. You can save battery life to some extent by few steps. First go to location services and bettr 'Off' them which are not needed. (Ex. Notes.. Reminders.. Etc). Also you can off few apps in 'get notifications' centre. Also usage of 3g by any mobile consumes much battery life. Better to connect any Wi-fi

IPhone 5s battery drain fast with iOS 8.1.2

I have iPhone 5s from 1 year. After updating to 8.1.2 battery draining fast. I needs charge the battery 3-4 times a day. I did the restore as new, but no change. Stopping the apps does not help. Please for advice.

I have also experienced this, but I think I have started to narrow things down. First of all, I am on an iPhone 5S 32gb, and I did NOT have any of these battery issues under 8.1.1, but since upgrading, the battery drains more quickly for sure.
What I have noticed, however, is that there are some strange correlations going on with what appears to be ridiculously severe battery drain - my phone will show 50% battery, and minutes later (of normal use, taking photos, screen at about 50% brightness, no overt internet or GPS activity) it will suddenly shut down completely. This seems to happen most WHEN IT IS COLD and I am using it outside.
When I try to turn it back on right after, I get the "plug me in" screen, as one would expect with a dead phone. However, if I wait a few minutes and let the phone warm up a bit, I hold down the power switch and on it comes, and when it comes on, the battery indicator will show 50% battery life again. I think of this as my FALSE BATTERY DRAIN problem, possibly unrelated to the actual battery life. I have only noticed this happening while running the Camera or Safari apps. Looking at my usage doesn't seem to turn up any surprises.
So Apple... what the heck is going on here? Is this an OS problem, is it an issue with your apps, with app conflicts... what is going on?
This is unacceptable. You know after being an Apple user for 35 years now I am not going to switch to Android lightly, but this is pushing me that way, and it is certainly going to keep me from updating to a newer, shinier phone until you show some commitment to supporting your users, who seem to be experiencing battery issues rather frequently these days.
Please at least show some INTEREST in being involved in this solution... I'm not seeing any indications of effort to fix this.
Thank you.

IPhone 5s IOS 8.1.1 battery drain using mail

Problem: battery drain is unacceptably high with -1% per five minutes
Description: after upgrading from IOS 7 to 8 the battery drain on my iPhone 5s (32GB) has hugely increased. Several tips on the internet have been tried from turning off several services to reinstalling the IOS none with no improvement. After reinstallation the drain was acceptable only to result in again a -1% drain per five minutes after a week.
Expected: using IOS 7 I could easily use the iPhone throughout the whole day with -1% per fifteen minutes. After installing an improved IOS one would expect similar or lower battery drain
Tests: as said, severals tips found on the internet have been tested none with any improvement. Deleting all accounts under "Settings->Mail, Contacts, Calendars" proved to be the only solution for this problem (a non-functional solution I must add since I'm using this iPhone for communication...). Even keeping the iCloud account but disabling all iCloud services did not improve the situation, only a real account deletion worked.
Question: do you know how to get battery drain back to -1% per fifteen minutes whilst maintaining my iCloud and Exchange account using IOS 8.1.1 on an iPhone 5s (32GB)?
Kind regards,
Ronald

Since upgrading my iPhone 6 to iOS 8.1, my battery has not been the same. I was able to get 9-10 hours of usage before and am lucky to get 6-7 hours. AppleCare thought that was on the low side and told me to visit my local Apple Store for a thorough diagnostic testing of the battery. My appointment is tomorrow. Will report back.

My iPhone 4 with iOS 6 is making me start to hate Apple. Any App and at any time I open and I can not view it or move for more than 2 minutes, they close themselves. During connections, it also gives this problem and the signal disappears after a few seconds back but often the person on the other end has hung up ... I can not stand it anymore, someone suggests something?
Besides these problems, there is the battery, which was bad got worse, she is not lasting more than 10 hours, even without using the phone.
Sometimes it even seems that the problem was solved, but my joy did not last long after I celebrate all the problems return, is incredible ...
thanks.
Sorry my bad Inglês.

Try a reset hold home/sleep buttons until Apple logo appears
If that does not improve try a restore

IPhone 4s with ios 6 shows full wifi signal but can't access to the internet while other idevice can

Hi everyone,
I updated my iphone 4s to ios 6 a few months ago and there was no problem until I change my sim card to other carriers last two days. This second sim card is the same sim card that I used it earlier this year with no problem. But the problem I face is when my iphone goes to sleep mode I realised that I can't receive any push notification from imessage, Whatsapp, and Line. When the phone is awake the wifi signal is back and I have to go to each application in order to get the message. I have tried the following methods but it didn't work: reset all network settings, restore as new iphone, push home and power button together, switch off my iphone, turn on airplane mode, and even change my router. At the moment I have restored my iphone as new for the 5th times.
Now the problem is worsen, after the phone is sleep for about 5 minutes and when I awake my iphone it shows the wifi signal. But I can't access to the internet at all. It shows no working internet on Whatsapp. Safari can't load any web page, the weather app can't update temperature etc. I have to switch off and switch on wifi in setting menu so that I can use the internet. And when I leave my iphone four about 5 - 10 minuetes then the problem start again. While I can't access to the internet on my iphone 4s, I used my dad's iphone 4s with ios 5.0.1 and it works just fine with the internet. My laptop can also access to the internet with the same wifi network but not my iphone.
Does anybody know what's going on with my iphone 4s? Is it the bug from IOS 6 or my iphone is broken? Please help me.
Thank you.

Any update will cause problems for a few users. And those users will rush here and post "the sky is falling" stories about their experience. The 99.99% of people who have no problems after an update won't bother to post here; indeed, most of them don't even know ASC exists. FWIW, I had no problems with iOS 7 on my 4S. Your problem is most likely not related to iOS 6, but you should probably update anyway. For addressing the battery issue see this outstanding article: http://www.overthought.org/blog/2014/the-ultimate-guide-to-solving-ios-battery-d rain

I have an iPhone 6 with ios 8.1.1 operating system. The Bluetooth pairs with my Sony car radio and works fine. However, the iPhone will not stop searching for other devices. This does not seem to affect anything, but I can't help but think it is using battery power.

One possibility:
How do you know it is searching for other devices? Because you opened Settings > Bluetooth?

How to I get itunes radio on my iphone four with ios 7

How to I get itunes radio on my iphone four with ios 7

So I was having the same issue and through guess and check I think I figured out the problem.
Essentially iTunes Radio is only available in the US, hence your phone needs to know you're within the borders of the USA.
I went into Settings > Privacy> Location Services > System Services (at bottom of the screen) and started playing around with some location systems I had turned off to preserve battery life. As soon as I turned on the "Setting time zone" function, iTunes Radio became available again.
It looks like Apple uses that system service to determine location of the phone and thus the availability of iTunes Radio.
You may have to close out the Radio app and restart (or even restart your phone) to make it work but so far so good for me.
Good luck!

Hello there, parihargs1.
To troubleshoot display brightness issues the following article provides 2 key steps:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
Of note is the following:
Display has no backlight or dark screen
Toggle the ringer switch to see if the unit vibrates. If it does, it could be that iPhone is getting power, but is not displaying any image.
Try turning iPhone off and then on again.
While connected to the iPhone charger, try to reset the iPhone.
If the low-battery screen appears, charge the iPhone.
Display does not adjust brightness automatically
The ambient light sensor brightens the display when using the iPhone in brightly lit environments, and dims the display in low light. To test this sensor, do the following:
If the iPhone is in a protective case, remove it from the case. If there is a protective film on the display, remove the film.
Verify that the Auto-Brightness setting (Settings > Brightness and Wallpaper) is set to ON, and that the Brightness level is set near the middle of the slider.
Press the Home button to return to the Home screen and then press the Sleep/Wake button to lock the iPhone.
In a bright environment, cover the top third of the iPhone to block the light, then press the Sleep/Wake button or the Home button to wake the phone. Slide the slider to unlock the phone.
Notice the brightness of the screen and application icons; they should be somewhat dimmed.
Remove the cover from the top of the display and in a few moments the display should get brighter.
If these steps do not resolve your issue please refer to the "Issue not resolved" section for your next step.
Thansk for reaching out to Apple Support Communities.
Cheers,
Pedro D.
