  • IPhone 5 battery drain since iOS 8.2 update

    hello,
    my name is Udi, from Israel.
    i have an iPhone 5 which i purchased in June 2013.
    since the beginning, i have always kept the battery saving "rules", including correct charging of a lithium ion battery, auto-brightness off, reduce motion on, push notifications off, background app refresh off, cellular data off when not in use, etc. etc.
    since updating to iOS 8, my battery life has decreased a little. but since updating to iOS 8.2 a few days ago, i have experienced, what is in my standards, a serious battery drain. e.g. when i sleep, with my iPhone on airplane mode at night battery decreases by ~15%.
    i have tried everything, including restoring the phone and using a backup.
    what can i do?
    will a restore from scratch (without using a backup) help?
    thanks in advance =)

    If this does not help, get your phone checked by visiting an Authorized Apple Service Provider or Apple Store next to your place, or contact Apple Support and talk to them. They can check the battery online.
    You can also visit this page to do that: iPhone - Contact Support - Apple Support
    Click on Apple Support, then on ->Battery, Power &Charging ->Battery questions and troubleshooting, and follow the instructions.

  • Iphone 4S battery drain with iOS 5.0.1

    I am experiencing just about the same battery drain with the iOS update as I did before.
    I was wondering how many of you had the battery drain problem, updates to iOS 5.0.1 and had that actually solve your battery problem.

    I have IPhone 4 and I updated the IOS to version 5. After the update the battery lasts about a day. After the update to 5.0.1 the battery lasts a day and a half. It is an improvement, but not as I expected.
    The next step is to disable configuration options like:
    - downgrade from 3G network to 2G
    - disable Data services
    - disable automatic clock
    - disable location services
    - use the phone only as a phone and nothing else.
    I will come back to tell how much the battery lasts.
    PS: the IPhone 4 is new so there is no problem with the battery itself.

  • How to fix iPhone 4s battery drain on iOS 5.0.1

                                                           Please Read this entire post for my fix
    FIRST OF ALL I MUST SAY THAT THE BATTERY THE 4S IS A BEAST!!!!!!!!!!
    I would like to add two steps to this.  I am a pure believer davidch you are unto something.  I did all your steps and i went from 100% to 81% in two and a half hours...I was saying to myself "this mess don't work!" lol....BUT I decided to do a little investigating on my own.
    I looked at my usage meter and realized that the actual USAGE TIME and STANDBY TIME were only 13 mins apart.  However i knew for a fact the phone was sitting on the couch WITH THE SCREEN TURNED OFF next to me for 2 and a half hours.  I may have picked it up once or twice after receiving a text and perhaps sending a text or two but that's it! My approximate REAL usage was around 5-10 mins. 
    Even tho I looked up in the top right corner and did not see the gps symbol, I was still curious.  So i pulled up my multitasking menu (double tap home button) and noticed that after the reset there were multiple apps still available to be selected from.  Not a surprise because we did a settings reset and not a complete content reset.  My whole idea was to selectively remove app by app from the list until i found the culprit that was running in the background causing this fiasco (our fiasco).
    IT WORKED!! I narrowed it down to the camera app. Which happened to be the last one that I eliminated.  Then i started seeing the difference between my usage and standby meter grow larger and better even tho i was checking frequenly (about every 15 mins).  I CLOSED THE CAMERA APP AT 12:30PM TODAY.  At this time my battery has dropped down to 77%.   AT 2:00 MY BATTERY LEVEL IS AT 76% What an improvement!!!!!!!!  But was the camera app the problem??? NO NO NO NO NO
    My guess is after the settings wipe all apps that were running ended up in a crash loop.  Because after that i opened up all the apps that were running previously plus some extras and as of 2:41PM THE IPHONE IS STILL AT 76%.  With approx. 3hrs of usage and over 5hrs of standby now.  With about 20 apps running including the camera app!
    I also did turn off siri raise to speak and did a reboot. Because after turning off RTS the infrared sensor on the front stays enabled until a reboot is executed.  So here are my steps mixed with davidch's that worked for me.
    For anyone new to the thread be sure to go through these steps to address the battery after updating to iOS 5.0.1:
    1. Reset all settings (settings app-> general-> reset)
    2 a. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose setup as new phone (don't worry your apps, data, contacts, mail will still be there). Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)
    2 b. If you do not get the complete new setup screen with language setup and setup as new phone or restore from iTune/iCloud backup, be sure to go back to #1 and reset all settings again (it should happen the second time)
    3. Turn off system location services timezone and iAd (settings -> location services -> system services)
    4. Fully discharge battery (until you get the spinning wheel and it shuts off)
    5. Fully recharge battery (overnight if possible)
    6. Go to General->Siri....turn raise to speak off
    7. Hold power and home together for a few seconds until the apple logo shows up. (Reboot)
    8. Double tap home button exit all apps running and you should be good to do...
    i didnt reboot after step 8 but maybe you should if you have a sprint or verizon iphone.  2:55 AND I AM STILL AT 76%  I think i am in love all over again!!!!

  • IPhone 5 battery draining after iOS 6.0.2 update even on standby mode without wifi/ 3G at all.

    My newly bought iPhone 5 was on iOS 6.0.1
    everything worked fine and i had no wifi nor battery issues at all until I upgraded it to iOS 6.0.
    i noticed some battery drainage even when i'm not using my phone at all it still drains 1-2% on standby mode with no wifi nor 3G at all in an hour,
    If i use wifi it'll drain 4-5% in a few minutes time, more serious case when i use 3G, it's literally draining in EVERY SINGLE MINUTE.

    Per designed, Wi-Fi will disconnect in sleep mode to save battery.
    If you want Wi-Fi to stay connected even in sleep mode, plugin to a wall power socket.
    No it's not "per design". It's not supposed to disconnect when locked/in sleep mode. The whole concept of having live notifications to work when your phone is locked is the standard for smartphones. Having this feature only accessable when pluging/charging the phone is rediculous and counter-productive. But it's good to know that I'm not the only one who has this issue. I hope all our issues are solved swiftly, good luck to you all

  • Iphone 5 battery drains rapidly, I have turned off apps and location even purchased a new battery, is anyone else having this problem?

    Iphone 5 battery drains rapidly, I have turned off apps and location even purchased a new battery, is anyone else having this problem? If anyone knows how to fix please let me know. I've tried the hard reset and nothing works.

    There was a run of bad batteries for the iPhone 5. Apple will replace them if your phone qualifies and you haven't tried to fix it yourself. See: iPhone 5 Battery Replacement Program - Apple Support. Unfortunately, you may have disqualified yourself if you tried to repair it yourself.
    However, rapid battery drain is only rarely caused by a bad battery. A bad battery is usually diagnosed by a battery percentage that jumps randomly. See this for advice: http://www.overthought.org/blog/2014/the-ultimate-guide-to-solving-ios-battery-d rain

  • Iphone 4s battery draining extremly fast

    iphone 4s battery draining extremly fast, how annoying is that, Battery will be drain out within 12 hrs and I just usually watch 30 mins video (not using 3G/wifi) and 10mins on Phone .
    I always turn off my Siri, Auto Detect Time Zone, 50% Brightness, NO background Apps are running and Mail is manually updated.
    Does anyone facing the same problem?

    Go to advanced and set icloud to manual I used to suffer from this because of icloud it was stuck in a loop and always draining the battery, try also resetting your network settings if it didn't work reset all settings and set it as a new phone drain the battery and charge it from 0 to 100% to recalibrate the battery , hope this works for you

  • My iphone 3gs battery drains very fast

    my iphone 3gs battery drains very fast it won't last for whole day
    i just uses mail application and  facebook for some time
    can u tell why the problem is or need to change battery

    I'm having the same problem with my 3Gs.  In my case it is not the apps int he background or the brightness, or wifi or email push.  The folks at the apple stroe tell me that there is some software glitch that shows up every few months.
    I can only get rid of it by restoring my phone as a new device.  In which case I lose all of my contacts, settings and all data.  VERY frustrating. I had recived two new phones (before applecare ran out) and have done the resotre several times.  No one can tell me what is in that creates this probelm.  I've tried differenet chargers one by one in case they are the probelm.  one int he car, one in a kitchen outlet, one at my home computer (sync) and on at my office computer (non-sync). 
    Problem just showed up again randomly two days ago,  no new apps or hardware.  battery drains from full to 0 in two hours.
    Apple, please fix.

  • IPhone 4S battery drain! after update is even worse, iPhone 4S battery drain! after update is even worse

    iPhone 4S battery drain! after update is even worse, iPhone 4S battery drain! after update is even worse

    Settings -> General -> Backroung App refresh
    Either selectively disable the ones you do not need, or just disable the feature altogether.  Esepcially for apps that would be using location services, this has the potential to be a huge battery drain.
    Also, in Privacy under Locations services, system services, disable at least the "popular near me" and "location based iAds" - both of these use location services a lot as they try to track your movements in real time.  You can disable everything in system services if you wish (won't harm anything).

  • IPhone 4S battery drain problem with iOS 7.0.4

    I have a had the iPhone 4 for a year and a half...The battery was working just fine with the iOS 6 but when updating to iOS 7..Things got a bit ridiculous, battery drains 4% in 10 minutes without WiFi. With Wifi it drains about 8% in 10 minutes with only one application used which is Safari. I usually turn off the WiFi and shutting all the applications of before putting on Standby to help in battery time efficiency. I reset all my settings as most of the tutorials say. I don't use GPS and closed most of the notification center applications that I don't use. Battery only lasts like 3 or 4 hours of continuous work with WiFi and low brightness..I'm seeking some help from Apple Technical support WHOM I tried to contact but with no answer.

  • Solution to Iphone 5 battery drain iOS 6.02

    Like many people I just bought a new Iphone 5 and noticed that the power drains very quickly compared to my previous Iphone 3GS, 4 and 4S. I tried many of the suggestions online such as turning off wireless, brightness, deleting this and that. I even tried to downgrade to ios 6.0.1 which failed as an error message showed up.
    Then I came across a youtube that solve it, the link is at http://www.youtube.com/watch?v=BkfU-OvQVp8
    Warning: Before you do anthing, read the backup/restore info in the end of this message
    Solution
    Basically what you need to do is
    to go Settings->General->Reset->Erase all content and settings
    Activate the phone as a NEW phone
    Plug into itune and setup as a NEW phone
    That's it!
    Results
    From that point on, my iphone 5 battery went back to normal. I turned on all my wireless, bluetooth, email push notifications, ie turn on all the smartphone functions as it should be. My 3G speed even improved tremendously from 500ms ping/1Mbps down/0.06 Mbps up to 99ms/9.51Mbps/0.34Mbps at the same location when I tested using speedtest.net app (several tests done. My data plan is still on 3G so I did not turn on the 4G or LTE functions of the iphone 5.
    Backup/restore
    Because you are setting up the phone as NEW, you cannot restore any data from itune. What you can do is to backup to icloud BEFORE carrying out the solution. This will backup your contacts/pictures/etc. These will then be downloaded back into the iphone from icloud after the phone is setup as new.
    However, some Apps such as WhatsApp, Apps that have data that are not icloud supported will need to be backup and restore using other methods. This depends on the Apps.
    Hence BE WARN, do your own backup and find your own restore methods because for this to work, you cannot use itune restore from backup function.
    Does it work for you?
    I hope this works for those Iphone users who is restoring their previous 3/3GS/4/4S backups from ituen into their new Iphone 5. I don't know if it works for totally new user of a new Iphone 5.
    If this works for you, leave a comment here so that it will help others.

    This is a follow-up.  I called Apple Support.  They had me go through a sequence of unplugging the phone from the computer, then rebooting the computer, unplugging and shutting down the phone, plugging in the phone while holding the Hold button to force a  restore.  It then finished the update and all is well.  I wouldn't suggest trying this without having Support on the phone.

  • 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.

  • Iphone 4s battery draining very fast and phone getting hot - downloaded ios 6 about 2 weeks back

    my iphone 4S gets discharged in few hours - started doing this 2 days back
    I downloaded ios6 about 2 weeks back
    Phone getting hot too
    battery drains even without using the phone- and phone becomes hot
    have tried turning it completely off and restarting it but still battery draining problem persists
    please guide

    I final piece for me in the jigsaw following on from this
    http://www.care4pcs.co.uk/2012/10/how-to-be-happy-gmail-user-on-iphone-or.html 
    is to turn off wifi when you do not need it. When I leave the house I turn off wifi, because the majority of the times when my iPhone has got very hot and crashed is when I am away from home. I suspect that if the iPhone is in the vicinity of public wifi (wheather secure or not secure) it will try and connect, even if you have 'automatically join known networks' set to off. This is easy of course if you have an unlimited data contract for your iPhone. I may be wrong, but it is working for me. It makes sense for me because it is another way of reducing the work the processor (and battery) has to do and therefore reduces the chance of overheating.
    Having said that, I never had this problem with my iPhone 4. I now have a 4S.
    Try it. Hope it works for you.

  • 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.
