Does 4.2 fix 4.1s battery drain problem?

or make it worse?

Neither. 4.1 does not have a battery drain problem, your iPhone has a battery drain problem. You need to fix the problem at its root. Every version has caused problems for some people, and it isn't a problem in the release, it is a problem with something getting corrupted during the update process. Here's the evidence:
New iOS 4.1 is a battery KiLLER!
iOS 4.1 drains battery
Battery Meter/Life Problems with 4.0.2
4.0.2 guzzling my battery. Your's too?
4.0.1 battery life
Battery runs out very quicky in iOS 4.0.1
Battery nearly nonexistant after 4.0 upgrade
Dead battery after few hours on standby using 4.0 software
3.1.3 battery problem
OS 3.1.3 battery issues
3.1.3 upgrade - shortened battery life?
Battery life cut after 3.1.3 update on iPhone 3G
3.1.3 Firmware is a battery killer - how do I back out this upgrade?
Poor battery life with iPhone 3G running 3.1.2
3.1.2 EXTREME battery drain - what gives?
3.1 Battery nightmare
iPhone 3GS with fw 3.1 – battery life gets even worse

  • Want to Fix iPhone 5 Battery Drain? (A Workaround)

    iPhone 5 (US - AT&T GSM - MD634LL)
    iOS 6.0.2 (10A551)
    Note: What I will detail/propose below is the implementation of a workaround to make do with what we have until Apple provides the solution.
    The hard truth to swallow for loyal Apple customers and device users is that the hardware Apple used in the iPhone 5 is power-hungry, services provided via iOS are not optimized to reduce resource consumption, and if Apple did not also include a bigger battery with the iPhone 5 then owners would be even more upset.
    So, long story short...
    Over five nights, I did some simple tests.
    The first night, I left my phone in Airplane Mode overnight - some drain while idle.
    The second night, disabled Spotlight Search indexing and left my phone in Airplane Mode overnight - minimized drain while idle.
    The third night, I turned off wifi - small amount of drain and I noticed that my cellar data usage (sent and received) increased by just over a couple of megabytes in total. Strange...
    The fourth night, I enabled logging on my router. Since all of my wireless devices are assigned static addresses, I can narrow down data hogs pretty easily and see where they are going to get data and how much data was sent/recevied. With wifi left on, many hundreds of requests were sent to push*.apple.com servers by my iPhone 5 and a couple of megabytes worth of data were sent/received. Why? Because I had push enabled for iCloud (I always set my email accounts to Manual data fetching). It seems to me that push is still not push and that iOS will check to see if updated data in iCloud needs to be fetched. Push in the iOS world is another way of saying "try to fetch data much more frequently than the periodic fetch data settings." I also looked at my OpenDNS stats since I got the iPhone 5 in early December and these servers made up a hugely massive chunk of all my internet traffic at home. It is fair to note that my wifi-only third-generation iPad makes many hundreds of requests to those servers as well, but I am guessing that the hardware used for it is not as power-hungry and I do not have BT enabled and I do not have any battery drain while idle issues with it.
    The fifth night, with both push and fetch disabled, all notifications disabled, as many location services as possbile disabled, all cellular data services disabled, Spotlight Search not indexing anything, I left wifi and cellular on and noticed that my battery drained only a couple percent while my iPhone 5 sat idle on my nightstand and only a minimal amount of cellular data was used (for what I do not know...).
    So, until/if Apple decides to do something, if you want to maximize your iPhone 5 battery's charge, then I recommend implementing the following:
    High Prority Settings
    If you do not use it, turn off Spotlight Search completely by deslecting all of the items that it can index. As with newer versions of OS X, services related to Spotlight Search indexing seem to run quite often and for extended durations of time.
    Unless you are a doctor or a very important person in another profession that must know when you get a new email, turn Push off and set Fetch to manual for all iCloud and all mail accounts. You can also go one step further and set each account to "Manual".
    Unless you connect to a very underutlized 4G LTE network, turn off LTE. I tested this change and the difference between standard 4G and 4G LTE on AT&T network in Denver metro area is negligible.
    Turn off ALL iOS System Services for Location Services. They do nothing but track you for your Apple's location-based advertising platform. For most, setting the time zone is done when the phone connects via celluar or wifi, and, my car has a navigation system with traffic data and I use Google Maps if I need navigation or traffic data when not in my car. Not a single Apple iOS System Location Service is absolutely necessary and will drain your battery.
    Medium Priority Settings
    Disable using cellular data for everything if possible. I still choose to leave it on for "iCloud Documents" and that doesn't seem to hurt things.
    Disable Location Services for as many apps as possible/reasonable. Do at least leave "Find My iPhone" enabled. Note that some other apps may require that they be able to use your location (e.g. SiriusXM).
    Disable as many Notifications (everything about Notifications - banners, alerts, badges, sounds, etc.) as possible.
    Low Priority and Typical Settings
    Reduce screen brightness as much as possible. Approximately 33% seems to suffice. Auto brightness can be left on since it seems to never really be used anyway.
    Turn off Bluetooth when you do not need it enabled.
    Turn off any automatic downloads for iTunes and App Stores, and Podcasts.
    So, yep, a total PITA. But by doing all of the above, a full battery charge lasts several days with 10+ (or more) hours of actual usage. I hope this helps anyone else that attempts to do the same. Screenshots for those unfamiliar with the key settings above are included below (everything is done via the Settings - aka Preferences - app with a "gear" logo).
    Disable Spotlight Search Indexing
    Push and Fetch for iCloud and Mail Accounts
    Turning Off LTE
    System Location Services
    Celluar Data Settings
    Notifications
    Automatic Downloads (apps, music, iBooks and podcasts) for "iTunes & App Stores" and "Podcasts"

    Hello,
    I am currently an owner of an Ipod Touch 4th generation.
    I have had battery drain problem on the Ipod Touch 4th generation.
    But, I found a solution that works for me:
    Do the IOS update (the one that is the latest, or if you already did, then proceed to step 2)
    Reset All Settings: SETTINGS>GENERAL>RESET>RESET ALL SETTINGS
    Use it until it dies (automatically shuts off)
    Plug into Charge
    Leave it 1.5 hours or longer after it reaches 100% --> Undisturbed (preferably overnight)
    Give it a few days to Calibrate
    This has helped me on my Ipod Touch 4th generation, running IOS 6.0.1
    The battery seems to give me 2 days 30 hours of standby, and 10 hours and 15 minutes of usage.
    Thats pretty good!

  • Anyone on T-Mobile UK that does NOT have the iPhone 4S battery drain

    Hi,
    Just wondered if anyone is out there who is on the T-Mobile network, and is not having battery issues with the iPhone 4S?
    Every SIM card from T-Mobile I tried in my phone gives me the drain.
    SIMs from other providers (so far, O2 and Three) appear to be fine (i.e. they FIX the battery drain problem).
    Even had T-Mobile replace my SIM, to no avail.
    Just wondering if it is the type of SIM they use?
    Please leave a note if you are on T-Mobile, and whether you have the problem or not.

    I thought it wouldn't be that, but I don't understand why when I put a SIM from another provider in, the drain immediately stops, and the phone works normally.
    I have tried completely factory restoring my phone, and not putting anything onto it, just using it on its own, with the SIM in it.
    The drain is still there, which suggests it isn't a problem with the settings for me.
    Flight mode doesn't help - drain still there. Removing SIM fixes it instantly, or, as I say, using a SIM from a different provider. This is really strange.
    Unfortunately I am tied to a contract, and can't switch providers at the moment...

    How to fix iPhone 5's crapy battery drain problem

    It's not that bad bro. Just turn LTE off when not needed. Turn notifications, push, spotlight search, wifi, etc off if you don't feel the need of them. The big drain is from LTE so I guess if you turn it off the battery wont drain that fast.

    iPhone 4S, iOS 5.0.1

    I have recently brought an iphone 4s and the battery is draining even without much use. please advice if any one is able to fix it with some patches or updates  iOS 5.0.1
    I have personally seen the problem and corrected it on numerous models now including the 4S, 4, 3GS and iPad 2s.  Corrupt system level settings created by an iOS 5 bug in the original release that caused battery recalibration issues, etc.  Just installing the update does not fix the issue in most cases (sometime it initially can be worse).  You need to clear out those settings and recalibate the battery.  For those still having the "standby battery drain" issue follow the procedure below in order.  It does fix the problem in most cases.
    Go through these steps to address the battery after updating to iOS 5.0.1:
    1. Reset all settings (settings app-> general-> reset)
    2. 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). At this point, Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)
    3. Turn off system location services timezone and iAd
    4. Fully discharge battery  (till it shuts off with the spinning wheel)
    5. Fully recharge battery (overnight if possible)
    In my experience this improves the standby battery drain issue significantly in most cases.  It reduces drain from 2-4% or more per hr to 0.5% or less. It has worked for many, many users now... not all, but most. If it does not work after a few try's you may have a real battery or hardware issue and should contact Apple.  Good Luck!

  • Is the 10.7.2 fixed battery drain problem ?

    there is no information anywhere and I wonder if this problem is fixed ?

    I wonder what percentage of users has that problem? Maybe I need to retest that one Unibody MacBook battery again with Snow Leopard, we always got poor life with Windows on it.
    I will double check also the new 2011 MBP, unfortunately, we have no reference to what is a good battery life on that one. It is a new system. It definitely had no effect on our old white MB.
    (Now I am having serious battery life problem with my 2010 Touch could that be an OS?)

  • What does this mean? Is my battery the problem or is the software an issue??

    As you can see.....it is plugged in. It shows the top right battery icon at full, but you can clearly see it's not. This is one of the problems I've been trying to get sorted out. Holding the home and power buttons are not going to help me fix this. I don't want to restore. I did that a million times. Does this mean I need a completely new battery? It won't charge, it won't turn on without it being plugged in, and when I turn the phone off...the charging screen doesn't appear. When I plug it in, the phone just boots up. Are there others who have had this same problem? I doubt updating to the lastest ios would have caused this. Please help. Thanks.

    Ok, so I turned on the battery percentage indicator. It said the battery is at 3%. I also unplugged the charger and for some reason it hasn't shut off like it usually does. Now, I am trying to drain the battery. I put on a video and it still hasn't went down to 2%.........this all seems very strange to me.

  • Iphone 3GS 3.1.2 Battery drain problem

    Hi,
    Recently i have purchased Iphone 3gs with software 3.1.2. I'm facing a serious problem of battery drain. Without doing anything, the battery drains so fast. Is there is any way to over come this problem?

    Here's what I do that usually keeps battery life accurate. Drain the battery till it's dead, charge up full and do a hard reset while it's still plugged in and it usually works. If this fixes it just keep killing the battery and charging it full. If it acts up repeat steps above. Mine works almost everytime when it starts acting up. I was just trying things and this worked. Hope this helps

  • Has ios 4.3.2 solved the quick battery drain problem?

    My 3rd generation ipod touch lasted for days on a battery charge using ios 3.1.3 form A;pril 2010 until July 2010.  After upgrading to ios 4.0 and other "updates" through 4.3.1 the battery does not last overnight when the touch is turned OFF or sleeping.  Apple has not responded to my eleven requests for help and the 'Genius?' offered no solutions except to turn off WI-FI, locations and other functions that I spent $300. to use.  The touch is now out of warranty, so IT IS TIME FOR APPLE TO RELEASE A SOFTWARE FIX FOR THE QUICK BATTERY DRAINS CAUSED BY IOS 4.xx.x. 

    Not for me.  I upgraded to iOS 4.3.2 on my iPod Touch G3 and everything worked OK, apps and all.  Then the next morning it was completely dead after putting it in standby with a full battery the night before.
    I am VERY FRUSTRATED at what 4.2.x has done to the battery life on my iPod Touch.  I use it every day and until I got 4.2.0 I could count on it being there when I needed it.  Now I feel lucky that it even turns on.
    I can NO LONGER recommend Apple phones or Touch to my family/friends until this is fixed! 
    APPLE, PLEASE FIGURE THIS OUT!

  • Duplicated battery drain problems...need help testing.

    I purchased an 80g classic about two weeks ago. The last 3 mornings I woke to find the battery completely dead. Last night I listened to a song or 2 and then pressed the stop button to turn it off. After reading other post I decided to put my ear to the back of the iPod and sure enough the hard drive was throttling at what sounded like full speed. This got the best of me so I spent about an hour messing around and this is what was noticed.
    When launching music from Cover Flow, the hard drive throttles fast the whole time while music is playing causing the battery to drain in a short time. If you launch your music from albums or by artist you will hear the hard drive throttle for about 6 to 8 seconds then go silent. This is the way it should operate.
    Next problem was the battery draining overnight while turned off. This was found simply by launching again from Cover Flow. Launch an album then turn off after song starts. You will notice that the hard drive continues to run very fast until the battery is completely drained. If you go back into menus before shutting down it will turn off properly. Again this does not occur when launching by albums or artists.
    Cover flow = battery drain and this should have been found buy Apple before releasing to the public. It would be nice if someone from Apple would comment.
    I have version 1.0.2 loaded and can’t go back to test version 1.0.1. What I am trying to figure out is this hardware or software. My guess is software but if I can’t get a good feeling about this soon the iPod is getting returned.
    Can anyone help in testing this out, launch from Cover Flow and put your ear to the back of your iPod…listen for about 15 seconds, does the hard drive continue to turn fast? When turning off in Cover Flow, does the hard drive stay on?
    Please post results and software version, thanks.

    I have a Classic 160. With 1.0.1 I had few issues. I was mostly happy, but nervous about all the issues I read in these postings. Only problems I noticed with 1.0.1 were Cover Flow was a bit slow and high rez photos would not show up in manual mode. (But there's no excuse for that is there?) Syncing and battery life were fine. Then I installed 1.0.2. Cover flow works nice and smooth, but I too woke up to a completely drained battery even though I shut the unit down. With 1.0.1 battery seemed to last forever. Now the hard drive stays on after shutting off unit. I found the only way to turn it off is by rebooting the Classic - holding down menu and centre button. For $399 Canadian dollars I am very very disgusted with Apple. Why should a consumer have to constantly check the internet for discussions and updates? And the biggest joke of all is the Apple website offers NO ADVICE, but lets their consumers do all the problem solving for them. Amazing attitude. What's wrong with being upfront and honest that the new iPods have issues? What about the person who can't surf the web all the time for answers? Their Apple iPod purchase becomes a paperweight. My 2 gig keychain MP3 player worked better than this junk. I wish I never bought the thing. For a company like Apple to let the consumer figure out the issues is just not right. Where is firmware 1.0.3????

  • 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.

  • Battery drain problem - question if auto lock is problem

    Just upgraded from iPad2 to Retina iPad. Went smoothly with cloud backup and download but experiencing sever battery drain. Went to use it 2 days ago after limited use prior evening (taking minutes in Evernote for 2 hr meeting) and had shut off. Restarted and had 2% battery and totally useless. Recharged overnight to 100% but had no demands yesterday. That evening opened up and found I had 21% remaining.
    Did battery problem search at this site, made some adjustments, and recharged to 100% for this AM. Two primary adjustments were stopping Bluetooth and Autolock changed from never (iPad2 setting) to 10 minutes and wondering if the autolock feature is the problem as discussed in the next paragraph. Others I didn't change, gmail set to fetch/manual and Cloud is push. WiFi on and disabling like suggested in some threads would be a royal PITA having to turn it back on every time and counter to the Apple vision of useability. App Store is set to advise of updates. Each of those were like on the iPad2 where had no battery problem, except I didn't activate cloud until just prior to the upgrade. IOS on both machines fully upgraded to IOS 6.01.
    Interesting discovery this AM. While I set the Auto-Lock to 10 minutes last evening, the the iPad Cover lock/unlock is set "ON". It appears that the 10 minute Auto Lock is working, however, the automatic lock/unlock is not which would explain the battery drain when set autolock was set to never. This AM as I opened it, had to manually unlock it as opposed to having the cover unlock it for me. As I close the cover and peek under the edge can still see the iPad  illuminated until the 10 minutes kicks in...then manually unlock it again. The cover I am using is the heavy duty RooCase with magnetic clip and had no problem when using it with the iPad2. (Great case by the way!) Any suggestions? Thanks.

  • Why does my iPad Mini Retina Display battery drain so quickly? I will be playing some 3d games and it says the battery is 90% but I'll turn off and turn  in back on it about 30 minutes and the battery is only 70%. Why is the reading so inaccurate?

    I will be playing some 3d games and it says the battery is 90% but I'll turn off and turn  in back on it about 30 minutes and the battery is only 70%. Why is the reading so inaccurate? I understand that 3d games on high brightness will drain my battery quickly, but why doesn't it tell be how low it is to begin with? The other night it said it was around 35% and I turned it on in the morning and it was only 3%?

    Sorry there are some typos above, but you should be able to figure out what I'm asking. Let me know if you have tha same problem, know how to fix it, or know if apple is aware of the problem and is adressing it in a future update.

  • Why does my IPod touch 5th generation battery drain quickly? Is this a defect?

    My battery seems to drain in about 3 hrs or less when I play a game, listen to music, etc( when it's fully charged too) and I'm not even using the Internet . Please help me, if this is a defect then I'll return it to apple and get another one.

    Using the battery level meter in this manner is comparable to using your car's fuel gauge to calculate miles per gallon.  The only thing that matters is the total amount of operating time from full charge to auto-shutdown.
    Use an Apple wall-mount charger and charge overnight.  Do NOT use a computer USB port.  Then, operate it normally until auto shut-down (ignore any low level alerts that may appear).  I don't play games but I expect that you'll get six to eight hours.  An irony is that doing that test to determine the total operating time is also the exact procedure necessary to calibrate the battery level meter.
    I'm not claiming that you do not have a problem.  I am stating, however, that we don't yet know whether or not a battery problem exists.
    According to Apple:
    Use Your iPad Regularly
    For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).
    Elsewhere, Apple elaborates and explains that two half-discharges (or four quarter-discharges, etc.) equals one full discharge.
