Battery life on IOS7: possible fix

After upgrading to iOS 7, many have reported battery life as an issue. After trying out all the usual suspects (location services, motion etc.) I plugged my iphone 4S into power, reset using the Home and Power button, and allowed the phone to restart and recharge fully.
It appears to be a battery calibration issue. Before doing this, I was losing 30% in an hour. At this time, the battery drain is down to iOS 6.1 levels and looking good.
If you've noticed your phone powering off even at 10-20%, this may help you as well.

  • Battery life with ios7 and iPhone 4s steps to make it better...

    What steps do we take for improving the battery life of iphone 4s using ios7. My iphone is becoming unusable due to the battery life...I need it to connect with my two sons and it dies in less than a day.

    There are quite a lot of threads about battery drain and iOS 7, and a lot of advices on the net basically telling you to disable everything (GPS, notifications, iCloud and so on) or to wipe your device and reinstall everything from scratch ...
    Something works, something not, but basically there is a bug in iOS causing most of the iPhones to have battery drain issues.
    Last attempt I did is to disable iCloud safari sync, since it seems to send data every few seconds.
    Standby time greatly improved, but usage time still ***** (compared to iOS 6).
    I really hope for a fix from apple ....

  • Macbook Air mid-2012 battery life issues -- a possible culprit ?

    Hi all,
    I've posted and followed a thread regarding diminished battery life for the mid-2012 MBA, when Mountain Lion was released. I never could fix the problem, was contacted by Apple but that didn't solve anything either.
    The troubles I was (and still am) having with my MBA were :
    Battery life reduced by at least 33% when I upgraded to Mountain Lion from Lion, following a firmware update.
    No change when I clean installed ML.
    No change when I upgraded, and then clean installed Mavericks.
    My battery, after 13 months of use, had its capacity reduced to 70-80%, and has now been stable for one year at 70-80% capacity. It now lasts approximately 3 to 4 hours, and has never lasted longer than 5 hours since I upgraded to ML, which was a few weeks after the laptop was purchased...
    I've tried everything that was posted on the forums, SMC resets, etc. Now to the (maybe) interesting stuff.
    I stumbled today on something interesting. I was researching my issue to see if people with the same laptop, that followed the same firmware upgrade path than I did had similar issues. Long story short, a forum post led me to something interesting, located at /System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/Plugins/ACPI_SM C_PlatformPlugin.kext/Contents/Resources
    DISCLAIMER Whatever you do, do not try to remove / move anything in this folder.
    What is interesting is that my Macbook Air has the following identifier : MacBookAir5,2. However, in the above-mentioned folder, there is no MacBookAir5_2.plist, it stops at 4_2.plist and then goes on to MBP models. Now, the question that I have is could the fact that this plist is missing be related to my battery issues ? In the sense that without this file, the kernel does not know how to properly manage the power, read the battery status / thermal sensors ?
    I would really love to fix this 2-year old issue that has been plaguing my laptop ever since I purchased it.
    Cheers,
    Hadrien

    1. Check the cycle count of the battery. It may be due for replacement.
    2. If not, follow these instructions.
    3. You can also try resetting the SMC.
    4. Make sure your system is up to date in Software Update.
    5. Make a "Genius" appointment at an Apple Store, or go to another authorized service center.
    Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

  • How do i improve my battery life with iOS7?

    SO with 6.1.3 i got about 8hours of wifi usage out of my two year old 4S. Now with iOS7.0 i only have 3-5hours of wifi usage!
    At first i only updated my phone, but i already knew that such issues may be caused by updating. That is why i already COMPLETELY restored the 4S and now i don't have anything besides my mail account on it.
    But i still only get 3-5hours out of it :/
    Why is this and how do i improve it?

    Does really NOONE know?
    I now restored my 4S, turned oof parallax, system services, location services, background refresh and push.
    But it still only get 4hours of wifi usage!
    With iOS6 that was not a problem!

  • Battery life issue related to display/graphics?

    Hi
    I bought a refurbished macbook pro last May. And the battery didn't even last 2 hours and half, which i found it weird since the macbook pro i had before(2007 model) had battery life of 3hours and half.
    a month later i bought it, i started having issues with screen. the screen started flickering/flashing randomly. i got the display replaced last week i think, but the screen is still having issues and battery life got even worse! now it lasts 1hour 45 minutes(screen brightness set at 50%) and i'm only browsing the web...
    (i asked the apple staff about it, and they said they ran a test and my battery is normal )
    it just got me thinking, if the issue is not in the battery, there must be something else that's affecting it...and maybe somehow the screen issues i'm having are related to the battery life.
    is it possible that something else is draining the battery power somehow..
    I was just wondering what people think about this... this is frustrating and i don't kno what to do...

  • New 2011 Pro - poor battery life, screen flickering

    Hello!  I recently purchased a new 2011 Macbook Pro 15" (8.2 in system profiler) and I'm having some issues with the graphics switching (I think).
    I get an average of 3 hours battery unless both Chrome and Skype are closed (no other applications).
    I tried installing gfxCardStatus to see which card was being used (integrated Intel or discrete ATI).  I found that having either of these applications open triggers the switch to discrete graphics and kills my battery.  I can use Safari instead, but I can't imagine that a browser would require the ATI card.  I can also understand Skype needing the ATI card for fullscreen video calling or something, but it runs just fine when I force it to use the Intel card, and it definitely shouldn't trigger the switch when just running in the background or messaging.
    Finally, and possibly the most strange of all, I tried running the Mac version of WoW and found it to be incredibly stuttery with constant tearing while using discrete graphics, or while using auto switching, or even without gfxCardStatus and having the system power setting to allow switching unchecked (forcing discrete to be always on).  After a few minutes, I started to see flickering all over the screen (about an inch long, 1 pixel high lines all over the screen, vibrating back and forth).  I removed gfxCardStatus and rebooted and haven't seen the problem since then (only been a day).  But the strange part.. when I forced Intel graphics (no ATI card) WoW ran perfectly smooth, even on moderate/high settings..
    I'm baffled.  In the end, this is a work computer that I use for web development, but the specs are definitely enough to play most games anyway.  My main concerns right now though are battery life and the possibility of a faulty card (the flickering).
    Thanks in advance for any input!

  • Does using bluetooth headphones dramatically decrease battery life in ipod 5

    I have a 64gb version of the Itouch 5 and recently started using jaybird brand bluetooth headphhones. At first everything worked fine but now the battery inthe Ipod only lasts 4 hours even when niot using it.  Has there been any known issues with this?

    Yes, and no. The headphones aren't sucking the battery out of your 5th Generation iTouch. USING BLUETOOTH, will. Its like running a game on your iPod for a while. It will drain the battery more quickly than with just listening to music. So running apps, bluetooth, etc, WILL shorten your battery life.
    HOW TO FIX IT:
    When you are not using the headphones, turn the bluetooth off through the general settings in your itouch. Then, while you aren't running the headphones, it won't suck the battery life out. When you use the headphones, turn bluetooth back on. Leaving bluetooth on is still leaving the iPod in bluetooth mode, which is running down the battery because it takes extra charge to run bluetooth. Hope this helps!

  • Z10 stl100 keeps powering off at 1/4 battery life

    Please assist me, I had this problem before where my phone powers off at 1/4 battery life remaining, I have fixed it but since I updated my software to 10.2 I can not seem to reset the battery meter and it is causing a problem,

    Hello,
    Depending on when you did this update, this could be normal. There is a period of time when a lot of activity is going on between the device and the network-based services to synchronize data, link contacts, etc. It has been reported that after perhaps 48 hours things "settle down" and return to normal. However, do be aware that each new OS will have a different "normal" for you when it comes to battery consumption...you must determine what is "normal for you" with this new OS and then only be concerned when things deviate too far from that new "normal".
    Good luck!

  • Terrible battery life after upgrading to Mountain Lion

    I upgraded to mountain Lion last week and now I'm getting only less than 2 hours of battery life. is there any fixes for this issue?

    Usually this means some process is using lots of CPU and hence lots of battery power.  (This certainly could happen after an upgrade if some third party software is now broken.) Have you looked at Activity Monitor (Utilities folder), All Processes, sorted by CPU?

  • Since upgrading my 4s to ios7 i cannot turn on my wifi and my battery life is halved how can i fix these probe?

    my tech nephew told me to reinstall io7 as it has been updated to resolve these problems (cannot access wifi and battery life is halved) Is this true and what's the best way to reinstall ios7?

    Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)

  • How I fixed my short battery life on iPhone 5, and ActiveSync problems at the same time.

    For anyone still having activesync or battery problems I have a potential fix:
    I've had two issues lately. 
    First, my battery life was draining at an insane rate.  iPhone5 lasted about 3-4 hours before absolutely dead from a full charge.  LTE disabled, WiFi disabled, icloud turned off...about as power efficient as I could make it, and I was hardly using it at all.  I was losing 1% batt every 2-4 minutes. 
    I solved this problem by removing my work account (Exchange Activesync) from my mail accounts.  Obviously I couldn't stay like that for very long, so after confirming it stemmed the battery issue, I tried to add it back.  Did a bunch of different methods and tests, and what ended up working for me was:
    Remove ALL accounts (Had Exchange, gmail, icloud)
    hard reset the phone. 
    After it came back up, I reset the Network Settings just for good measure. 
    In Mail control panel, make sure "Default Account" doesn't have an old mail account listed (option may be not even present if you've removed all accounts, but I was having issues earlier where even though I'd removed accounts, it kept listing them in the Default Account/Calendar sections
    Add the Account
    Open Mail
    It actually took a min or two to start populating data, I didn't think it had worked, so give it a few minutes.
    My battery life issue seems to be fixed, and my ActiveSync account works again.  I've been off the charge for about 4h 40m now, and battery is at 90%, and that's with moderate usage on LTE.
    Hopefully this helps out anyone having similar issues.  For what it's worth, I removed/readded my Exchange account several times and it never worked until I had removed all accounts (my iCloud account was the last one to be removed), so if possible, just remove everything.  I had already restored, DFU'd, and tried several other steps.  This was what worked for me.
    I have NOT added my iCloud account back yet, but will be doing this now to see if any issues reappear.

    I am experiencng rapid battery drain as well. Before checking the forums I have closed apps running in background, turned off LTE, turned off location services, turned off wi-if & turned off Bluetooth...my battery drained to 53% in 3 1/2 hours.
    This is my 1st personal iDevice so I do not understand some of the verbiage. 
    What is "disabled safari on icloud"? 
    I go to Setting - iCloud & I am not signed in
    I don't see anything in Safari Settings about iCloud
    Thank you in advance for your assistance

  • How to extend iPad's battery life? I've tried everything possible

    So basicaly I have this iPad 3 for 2 years now, and the battery keeps on draining. I'm not sure if it reached it charging times limit. I've tried everything possible, disable unneeded stuff, turn off background refresh, auto brightness etc. I've even booked a Genius Bar appointment and the person checked my iPad's calibration and it was OK, and he said its not needed and the cost (in CAD) would be about the same for a new iPad. Also charging is freaking slow too, even when I don't use the iPad while charging. Solutions will be appreciated if there's none I'll wait until the holidays and buy a iOS 8 iPad

    Could be the charger, cable or iPad. Plug the USB cable into your computer. It may say "Not Charging", however, it is charging slowly and will verify that the cable is good. If your computer/iTunes does not recognize the iPad, then the cable is probably bad.
    Try this first -  Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430
    The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
    Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.

    At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.
