Iphone 5s battery drains faster on ios 8.1.2

Hi,
Facing problem of battery drains faster after 8.1.2 update. Phone low signals, App store low signals

PPhone low signal? Are you saying your phone is having issue getting a strong cellular data signal? If so that is why your phone is draining battery at a faster rate.

  • 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 battery drains fast after ios 7.1 update.

    Am I the only one who seems to be experiencing this? My iphone 5S battery seem to drain much faster than usual, and charge longer. I heard that the new update is supposed to increase battery life, and read comparison threads regarding other iphones that are capable of a much better battery life than mine.
    I've had my phone for 3 months, never have dropped it once or anything of the sort, if that matters. My battery drains to 50% within an hour or so after intense use on the lowest level of brightness, and I seem to lose about 5-7 percents when on standby for 5 hours or so. Is this normal? Is it perhaps due to the fact that I am mostly using 3g, and applications that require more processing such as tumblr (graphics and gifs) as well safari? I'm just worried that my battery may be draining to quick, despite the update which's supposed to make it much better according to many people.
    Thanks.

    Me too.
    I went from plugging in to charge at the end of the night, around 11pm, to barely getting through a workday with very light use.  With less than 10 hrs of standby and maybe 30 minutes with the screen even on I am rocking 15% battery life.  I'm also connected to wifi whenever at home or in the office, which accounts for over 9 hours of the standby time.
    I know people are suggesting turn off features... but eff that, 5 days ago I'd get through an entire day without any issue, under much heavier useage.  I don't want to have to turn on bluetooth everytime I get in my car and back off when I get out, I just want it to work when I turn the car on... I don't want to manually check for emails, I want it to tell me when an email comes. 

  • IPad 2  AND iphone 4 battery draining FAST since IOS 6 update!

    I have done EVERYTHING I can think of and that has been suggested all over the World Wide Web to improve the battery life of both my iPad 2 and iPhone 4 since the IOS 6 software update. Nothing works!!!! I am leaving town in a week, and I would like my phone to be working the way it did before.
    Still taking suggestions to fix this.
    APPLE please do something. I am losing faith, and I am also losing my desire to buy the new iPhone 5!
    APPLE PLEASE HELP!
    Thanks in advance!

    Have you tried closing all apps? Double tab the Home button, then tap down on an icon and hold for about 3 seconds, until the icons are moving slightly. Click on the above every App.

  • Iphone 6 battery draining fast

    Jus bought my phone and my phone battery become hot even I only use it for 5 min and the battery draining fast is it my phone battery have a problem?

    Hi Mqchew,
    I'm sorry to hear you are having issues with your new iPhone. If you have a new iPhone 6 that you are concerned may be having heat or battery issues, you may first want to try restoring it to factory condition (if you have loaded any apps or data onto it) and testing it in that default state to see if the issue persists:
    Use iTunes to restore your iOS device to factory settings - Apple Support
    If the issue persists after the factory restore, you may want to take it in to be evaluated and/or serviced. You may find the following page helpful:
    Apple - Support - Service Answer Center
    For more general temp issues, you may also find this article useful:

  • Re: Battery Drains Faster in iOS 5 ?

    Hello,
    I have marked that Battery drain faster if using apps in iOS 5 then the previous version, but the idle time is better in iOS 5.
    In my case after fully charged, my phone show 100%  if its in idle mode for 7 hours, but as soon as i start some apps the battery drains faster, like if i use the apps for 15 min the battery remains at 80%.
    Have anybody experience this ?

    @dimoff: I didn't experience the same thing with other mobiles, even of Nokia. I have Lumia 525, Moto G(Dual Sim). My wifi is always on and i use the phone without any problem for 1.5 days.
    But where as Lumia 630, without any phone calls, only idel phone it could stand only for 1 day.
    On the contrary what i have experienced is when i use 3G, battery is consulmed more tha wifi.

  • Why does my iPhone 5 battery drain faster ever since doing ios 8.2 update? And how do I fix this problem?

    Hello paula.a.williams66,
    It may help to force close all open applications, then reset your iPhone.

  • Iphone 5 battery draining fast

    My 22 month old iPhone 5 has suddenly started draining its battery really fast. It loses 70% in 3-4 hours. Nothing has changed in my usage and I haven't upgraded to IOS 7 or 8.  My serial number doesn't seem to qualify for the replacement scheme for certain phones bought in 2012/2013. Is there anything I can do?

    You're iPhone probably is working too hard.  If the iPhone is in hot conditions, the iPhone actually works to try to cool itself down.
    -Make sure it's in a cool atmosphere.
    Also, all the apps you've ever used, the phone is still running.  To clear this off in iOS.6.1, you would double tap the home button and swipe up on the apps you don't want you're iPhone running.
    Delete usless apps, songs, photos, or anything that's usless!
    Do all this and I'm sure it'll help you're battery life! Hope this helps!

  • IPhone hot, Battery draining fast, dataaccessd crashing repeatedly

    I have been having problems where I find my iPhone battery has drained more quickly than normal, and I find it warmer than normal. Digging into it, I found that 'dataaccessd' and 'ReportCrash' are starting and stopping in the pid list. I am using a $2.99 iTunes Store program called System Activity Monitor to see the pids & CPU load. The CPU load is spiking every few seconds, which I guess correlates with the heat and battery drain.
    I followed the recommendation below exactly with this afternoon's episode, and it is still running the processor and burning battery, looping through 'dataacessd' and 'ReportCrash' afterwards.
    +Have you tried this simple tip?+
    +1) Hit home button twice to bring up active applications+
    +2) click and hold down mail until the red minus sign appears+
    +3) click on the red minus sign to quit the application+
    +4) hit the home screen and re-launch the mail application+
    +This has always fixed my mail issues. Note restarting the phone does+
    +not help, you need to do the above procedure.+
    I also cycled power, and it came back up with dataaccessd still crashing & cycling with repetitive spiking CPU loads. I also turned 'push' off earlier today (Fetch New Data / Push -> Off), apparently with no effect.
    I have the EAS profile installed per http://support.apple.com/kb/TS3398 with the DefaultEASTaskTimeout at 240. And it doesn't seem to matter whether the phone is on 3G or WiFi when this condition happens.
    As usual, the "fix" was to delete my Exchange e-mail account and re-install it. After that, I don't see 'dataaccessd' and 'REportCrash' coming and going in the pid list. This "fix" works, but going through this procedure 3-4 times per week is getting old, not to mention the unpleasant surprise of finding my battery has unexpectedly drained when I need to use my device.
    This is the first log entry (earliest) today at 13:39, when dataaccessd started crashing, before a slew of 4-6 entries per minute in the log directory on my Mac (after syncing) - see below.
    Question - any ideas how to fix this ? It was happening before the latest iOS upgrades so I don't think the standard "reload the os" answer is the fix....

    dataaccessed crashing repeatedly here as well, only when syncing with Exchange Calendar, regardless of push/fetch setting. Disabling calendar on this account stops the crashes. Re-creating account doesn't help. Problems started 2 days ago. More info on the crash from iPhone console below, collected using Configuration Utility, in case it can help someone. I suppose Apple automatically receives crash dumps for their own applications through iTunes ?

  • Iphone 4s battery draining fast

    I recently updated my iphone to software IOS 8, however my phone heats up very hot and the battery does not last more than 6 hours, even when fully charged beforehand. I have followed all of the guides online on how to reduce your battery usage, but they don't seem to work.

    Had the same prob as everyone else.  18-month-old iPhone 4s had good battery life until IOS 6.1.3 update.  Started draining at 7% per hour in standby -- Siri off, location services off, etc.  Went to local Apple store last Friday.  Phone slicked and IOS restored.  Walked around the mall for 45 minutes, and battery drained 7% in that time with one email (text only) and one 1-minute phone call.  Returned to Apple store and got another appointment on the spot.  Replaced phone since I have Apple Care.  What I didn't know is that the replacement phone had IOS 6.1.2 on it (realized that when I got a prompt to install the update).  I haven't done the update and battery life is fine!  So, if you can get back to IOS 6.1.2......

  • Iphone 4 battery draining fast and yellowish blobs on the screen

    So I got my iphone 4 today. 32GB. Came home charged it full powered down for battery memory and left off for a few minutes like instructed.
    I have not done much with the phone and I am already at 85% within an hour of using it for texting. maybe 30 texts so far. Wifi off, no tethering connection made, Brightness turned to max push every 15 minutes 3G on. For a battery that is 40%n bigger it is really draining fast.
    Now I am noticing yellowish blobs on the right side vertically and a few on the top horizontally. I read in a post that it was because of not cured residue and should go away in a few days. DOES this make sense to you folks. Where does it say that on apples site.
    I am about to call a tech about this and have them send me something in writing.
    This is just frustrating as I was hoping for a great experience this year. From the let down from the white iphone to my battery being drained to now yellow blobs..man can anything else go wrong.
    What say you??????? any of you have battery issues yet

    If my past experience with iPhones and iPods is any indication, you'll find that over the next couple days as you use your iPhone the battery indicator will become more accurate. My habit (as I've done with my new iPhone 4) is to use it until the indicator shows red and then charge it fully and then do that twice more. At that point the indicator should be 'calibrated' with the battery and be more accurate. Yesterday I used my phone for about 5 hours before the battery indicator gave me 20% warning. Today I've used it as I normally would in a day and, as I always did with my G3S, I'm currently home from work with a 40% charge showing. Guess I'll have to play a little Angry Birds tonight
    I've seen nothing official from Apple about the yellow splotches but I read either at Engadget or Gizmodo this morning that a worker experienced with this process claims it is the bonding adhesive which hasn't finished curing. It has been widely reported second hand. Don't know if contacting AppleCare this early in the game will get you anywhere. Since iPhones are in short supply at this time and you have a year's warranty, I'd wait a couple days and see if the report is correct. If the yellow defect goes away it was true.

  • 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.

  • IPad 2 battery draining faster with iOS 7

    Since upgrading to iOS 7, my iPad 2's batter has been draining much faster than before the upgrade.
    One thing that might be contributing to this is how 7 revamped how it displays "open" applications.  Prior to 7 if you hit the Home button twice it would diisplay a row of icons at the bottom showing which apps were "active" or "open."  You could press an hold any icon and all icons would go int wiggle mode, and you could select certain processes and quit them.  This I did regualrly.
    Now with iOS 7, tapping the Home button twice shows large images of the last screen in the apps shown at the bottom, showing just two or three, making it a slow process to side-scroll to find an app.  Gone is the means of quitting open apps as well.  My list of open apps is pretty long and I'm sure that with so many open processes, the batter charge takes a big hit.
    I've looked in all the system settings and don't see any way to toggle or set the system such that I can quit running apps.
    So, here's my two-part question:
    1.  What steps can I take to slow the battery drain?
    2.  How can I close open apps?
    Bonus:  How to revert the ugly "open apps" display back to something that resembles previous versions, particularly how to get rid of the screenshots that take up so much room?
    Many thanks!

    PS:  There ought to be a forum for iOS issues rather than forcing users to post in hardware-specific forums.

    If the drain seems extreme there may be something else going on.
    First try a reset: Hold the Sleep/Wake and Home buttons and don’t let go until the screen goes dark and the Apple logo appears (no data will be lost)
    If that does not help, backup & Restore the iOS Software

  • FIX FOR: iPhone 4 battery draining fast, phone running hot

    I had the same issue many have reported here and in comments on blogs, where their +_battery was draining at least twice as fast_+ as on an iPhone 3GS with iOS 4.
    Some threads suggest +_this happens to iPhone 4 when restored from a 3G or 3GS_+, and indeed, that's what I'd done. A few people said that resetting to factory settings and installing everything fresh solved the issue, giving them better battery life than they'd seen on any prior iPhone.
    Many of my apps have files or settings stored in them, so I didn't want to have to set everything up again. A fresh install is a real pain.
    Deep in an iPhone 3G thread mentioning a similar battery problem after upgrading to iOS 4, someone said they'd deleted all their mail accounts, and set those up fresh, which solved the issue for them. I tried that today, and it worked.
    *_BEFORE AND AFTER_*:
    Thursday and Friday, the iPhone 4 went from 100% to 15% in under 6 hours. Today, after this fix, the iPhone 4 is at 87% after 12 hours. Thursday and Friday the phone was hot to the touch whenever I picked it up. Today it's always cool. Apps usage and movement among coverage areas on each day have been exactly the same. The only change was resetting up mail.
    *_STEPS TO FIX_*:
    Do this on WiFi so you can sync and check mail fast.
    1. Delete all mail accounts.
    2. If MobileMe user, delete MobileMe account, and remove all Calendars, Contacts, Notes, etc., from the phone (so you don't have dupes when you re-sync).
    3. Turn off phone, and back on again.
    4. If MobileMe user, add MobileMe account first. I enabled all options, even Find My iPhone (Thursday and Friday I had it off, in case it was using power). Wait long enough for contacts and calendars to sync, check to make sure. I use MobileMe mail on Push.
    5. Add back each additional mail account. I have 5. I am in a marginal coverage area, so I set these accounts on Fetch Hourly. I also have "Preview 5 Lines" (I think the default is Preview 2 Lines. This doesn't matter.)
    6. Go into Mail, go to the MobileMe Inbox, and scroll your way down letting the messages come in. You can see them come in when you see the Preview Lines update, and then scroll some more.
    7. Go into each additional mail account's Inbox, scroll your way down, letting the messages come in.
    8. Go to the combined Inbox if you use that, make sure all the messages are in.
    9. The WiFi activity spinner may remain spinning even after Mail says it is done Checking Mail. This is because other parts of mail accounts are being synced for the first time. Let the iPhone sit in Mail combined inbox until the spinner stops. Quit Mail, go back in, and watch the spinner after it's done Checking Mail. If the spinner doesn't stop after < 5 seconds or so, let Mail sit again. Once it's caught up, going into mail will Check Mail, and the spinner will stop a few seconds after as it should.
    10. You're done.
    Hopefully your phone stays cool and your battery life reflects the boost from the 20% larger battery. If not, the next step to try is Reset Network Settings, and finally try a factory reset and installing everything fresh instead of doing a restore. Hopefully you won't need to do that. I didn't.

    My iphone 4 just started to warm up and the battery is draining quick.  Closed everything and reset to no avail.  Turned off bluetooth, increased push time and checked location settings for new applications.  Weather Doodle was a bit suspicious as it had a purple direction indicator next to the setting.  The only other new app I installed was Lego instruct.  I disabled one of the 4 mail accounts I had that is having network difficulties, went to airplane mode and still I see %1 drain every 10 or 15 minutes.  I'll remove the new new apps and reset to see if it is related to the new apps.  If that doesn't work, I'll try email account reset at home wifi and see if that fixes the issues.  
    Thank you for the information.

  • My iphone 5s battery drains fast, please help

    Hello, dilith
    Thank you for visiting Apple Support Communities.
    Troubleshooting battery life can be tricky as usage, environmental and other factors play a role in how long the battery will last throughout a day.  Here is a basic guide for settings that you can adjust to possibly prolong your battery life.
    Optimize Your Settings
    Depending on how they are set, a few features may decrease your iPhone battery life. The tips below apply to an iPhone running iOS 7.0 or later.
    Enable Wi-Fi: Having Wi-Fi enabled helps consume less power when doing activities that access data. Go to Settings > Wi-Fi and log in to a Wi-Fi network.
    Adjust brightness: Dim the screen or turn on Auto-Brightness to extend battery life. Turning on Auto-Brightness allows the screen to adjust based on lighting conditions. To enable Auto-Brightness go to Settings > Brightness & Wallpaper and set Auto-Brightness to On. Adjust your brightness when indoors in a non-bright environment. You can do this by going to Settings > Brightness & Wallpaper and dragging the slider to the left to dim. After making this change, turn Auto-Brightness off and then on again to reset to the default behavior.
    Fetch new data less frequently: The more frequently email or other data is fetched, the quicker your battery may drain. To fetch data manually: Go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly. Note: This global setting applies to all applications that do not support push services. If you receive a lot of email, you can turn off push email to save your battery. Go to Settings > Mail, Contacts, Calendars > Fetch New Data. Set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive.
    Turn off push notifications: Apps with Push Notification alert you of new data, which may impact battery life. To disable, go to Settings > Notifications, choose the app you want to disable, and do the following:
    Change Alert Style to None.
    Turn Badge App Icon off.
    Turn Sounds off.
    Note: New data will be received when you open the app.
    Minimize use of location services: Apps that actively use location services, such as Maps, may reduce battery life. You can see which applications have recently used location services by going to Settings > Privacy > Location Services. Apps that have recently used your location will have an indicator next to the app’s on/off switch. If you see an app that you do not expect to be using location services, you can disable it by toggling the switch to Off. To disable location services completely, go to Settings > Privacy > Location Services.
    Use Airplane Mode in low- or no-coverage areas: Your iPhone always tries to maintain a connection with the cellular network, which may use more power in low- or no-coverage areas. Turn on Airplane Mode to increase battery life in these situations. Go to Settings and set Airplane Mode to On. Note that you will be unable to make or receive calls with Airplane Mode on.
    Viewing Usage Statistics
    Knowing and understanding your iPhone usage can help you better manage your battery life. To view your iPhone usage statistics, go to Settings > General > Usage. Under “Time since last full charge”:
    Usage: Amount of time iPhone has been awake and in use since the last full charge. iPhone is awake when you’re on a call, using email, listening to music, browsing the web, or sending and receiving text messages, or during certain background tasks such as auto-checking email.
    Standby: Amount of time iPhone has been powered on since its last full charge, including the time the phone has been asleep.
    Lock Your iPhone
    You will still receive calls and text messages when your iPhone is locked, but nothing happens if you touch the screen. To lock iPhone, press the Sleep/Wake button. You can also set the Auto-Lock interval so your iPhone will lock after a period of inactivity. Go to Settings > General > Auto-Lock and set the interval to a shorter time, such as 1 Minute.
    Extend Battery Life if Storing Your iPhone
    If you will not be using your iPhone for a while, charge the battery up to 50 percent before storing it.
