IPhone's battery

Hey,
I bought my iphone 3g a week ago and it's amazing. But I think that there's something wrong with the battery: I used the iphone for 5h 40 min (wi-fi, music, camera, games and calls) and it was in stand by mode for 2 days 20 hours.
Is it normal to recharge it after this usage or the battery's not good?
Is it normal that the battery takes not more than 2 hours to recharge?
Thanks,
Camille

Both of those are perfectly normal.

  • Iphone 4 battery runs completely down with no use in an hour or two.

    My Iphone 4 battery, out of the blue, started running completely down in a couple hours with no use.  I would take it off the charger reading 100% and not do a thing, but the unit will get pretty warm and the battery drains.  The phone is only 3 months old and two days ago I was getting a full day to a day and a half with my ususal usage.  Anyone know what is causing this or a fix? I've tried shutting down and rebooting and for software updates?  Any advice is appreciated.
    Thanks, Josh

    One thing to try is cleaning iPhone Dock Port with a clean dry toothbrush.
    If still problem and you have Warranty or AppleCare Coverage take iPhone to Apple for resolution.
    Another is to clean the dock port again with the toothbrush and a bit of Isopropyll Alcohol, especially clean the pins which are on top of the Dock Mid Rib.
    Reset, hold both Home and Power buttons for about 10 seconds until the iPhone restarts itself, ignore the 'slide to power off' slider.
    Restore Firmware, at end when iTunes asks, Restore as New, not from backup.

  • 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

  • Iphone 4 battery sometimes drains fast -- problem with Mail app?

    My iphone 4 battery often drains too quickly, and I wonder if it has something to do with my Mail App.
    When my phone is not playing nice, it drains at least 20% overnight while on Standby, and from 100% to 30% in around 6 hours when I use it during the day. I found a fix (http://discussions.apple.com/message.jspa?messageID=11775150) that basically says to wipe your mail account and set it up again.
    This fix works, but only temporarily for me. I find that I have to keep resetting my mail every few days to get back to "normal battery" where it barely drains overnight. I only use one email account (gmail) -- could there be something going on there?
    Oh, and when my battery drains fast, nothing changes when I turn off WiFi, notifications, push, etc. I usually have my mail refresh hourly.
    Has anyone had this experience?

  • 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.

  • Is anyone else having a problem with the iPhone 4s Battery Life?  My 1 year old Iphone 4, which I gave to my wife, is holding a charge better and she has been using it far more than I've been using my 4s

    My wife preordered a white iPhone 4s for our anniversary and even though it is preloaded with the ios 5, i am a little disappointed.  The battery doesn't seem to hold a charge well at all. I have had every other iphone except the 3gs and have never had such a poor battery life.  I owned the iPhone 4 for a year, and already know all the tricks to hold on to battery life, I have adopted the habit of closing out any apps that weren't being used, my mail push notifications are set for hourly, wifi and bluetooth are turned off when they aren't needed.  I also stay away from any car chargers, use only the apple brand supplied cables, and only charge when the phone is dead.  I only would sync when the phone was about to die as well. 
    When I saw how fast I was burning through the battery, I turned off Siri, which is kind of the purpose of the new iPhone, and turned off the backing up to iCloud.  I barely used my phone today and the battery kept ticking down.  My wife, who has been stuck with an iPhone 3g for years, has been fascinated with my old iPhone 4 and has been browsing and playing games and her battery has been holding a better charge than my new phone.  I even tried turning the phone off for an hour when it was at 18% and when I turned it back on, it was at 15%. My iPhone 2, which is only being used as a touch iPod now, still has better standby time than a brand new iPhone 4s. 
    To be honest, I am usually a heavy phone user.  Throughout the day I will make and receive at least 50 calls, I browse and check websites daily and watch videos sometimes during my downtime.  But this weekend, I haven't even had the chance to put this phone through the same abuse my other 3 iPhones have had to endure. 
    I just want to know if anyone else has this problem, or if I should just return this one.   

    I had major issues with the iPhone 4s battery, however it’s resolved.
    The tech who set the phone up at the Apple store did so with little training.
    if you have a mobile me account. First go and move all your data to the cloud by going on your computer and logging in at me.com/move. The cloud has replaced mobile me, so there is no need for those two accounts
    Also make sure that for any of your email accounts you set them up to fetch, not push. My tech person set them all to have the email servers push data to the phone. The new iphone4s antenna is extremely strong so it will continually try to access stuff that is pushed–***** a lot of battery life doing this. It makes it worse if you have exchange 2010 accounts. Something about changes made to exchange really suck battery life from devices that access such accounts.
    turning of locator and the push notifications from facebook--they have a lot!

  • My iPhone 5 Battery Drains Too Quickly! Apps closed, bluetooth off, brightness, low, no notifications...What else can I do?

    My iPhone 5 battery life is terrible! The software is updated--ios 7.0.6. I have to charge my phone 2-3 times a day on some days. I have to close all apps, turn off location services, turn off bluetooth, turn off 90% of my notifications, lower the screeen brightness to less than 10-15%, and turn off all push notifications--all to get my battery to last until 6:00pm.
    I may talk on the phone 10-20 minutes a day, but check emails on my phone a few times in 10 hours. I am indoors most of the day so cold temperatures aren't at play (although if I do use my phone in the cold (less than 25 degrees), the battery drains within minutes!) If I leave  my Camera, Facebook, Maps, or the Weather Channel open in the background, my battery will go from 100% to 20% in less than 2 hours.
    I have been to the Genius Bar more than once. They replaced the battery about a year ago becasue it was bad. I returned a few weeks ago to have them checked my battery again and it tested fine. The Genius I spoke with wiped my phone and removed all data on it and reset it. Unfortunately, the problem has not been solved.
    Has anyone had similar problems? How did you resolve them?

    I set the phone up this morning as a new phone no back up.
    Brightness set to full
    No wifi
    No bluetooth
    No back ground programs running
    Fetch every 15 minutes for emails for half the day and then went to manually for second half
    3G for half day and 2g for second half
    tethering off
    thats all I can think of. My friend and I looked at all his setting and mine and they were both similar except he keeps his on wifi all day.
    we put them to exact same spec when i got to his house at 3. I had close to 50% from a full overnight charge and when I left at 7:30 I left dead and His was at 17% left still from the previous day and when I left his was at 8%
    I dont know

  • My iPhone 5 battery drain with in 3 hours when I use cellular network on and stand by time is only 2 and half day

    I Bought iphone 5 from USA  when I came to India I started it then I noticed the battery stand by time is only 3 days. And when I use cellular data then it is live only for 2 and half hour. I bought this phone in January till now I am having the same problem. I have done all the thing whatever the support center told me about restore and all stuff. After that they told me to visit any apple store but there are no store in India and I'm helpless. For my iPhone only I can't go abroad to that country where stores are. Before I used to believe that apple products are the best but this iPhone has just disappointed me. You know my friend making fun of my mobile because they are using samsung product.
    Pleade do some thing for me I have left only 2 month of warranty. other wise I will have to through this on dustbin because everywhere it is insulting me.

    Sorry, but the warranty for the iPhone is only valid in the country where you bought the device.
    In most of the cases 3rd party apps or settings caused the battery to drain faster than before the new software has been set up. Sometimes the mail app tried to connect to the mail server over and over again, deleting and setting up the mail account can solve this problem.
    In other cases social media apps did similar things to the phone.
    Here are some suggestions for getting back the normal battery life, maybe they are helpful for your problem with your iPhone 5 as well.

    iOS 6 iPhone 4s battery drain

  • 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!

  • IPhone 6 battery life draining since 8.1 update

    Is anyone else having problems with their iPhone 6 battery life diminishing since the latest 8.1 update? I notice I'm getting much less usage time per hour. For example, before 8.1, it would take about 3 hours of usage time to get to 70%. Now it only takes 2 and it gets worse after that. Here is a screenshot I took of the battery usage before the 8.1 update:
    This is pretty normal usage timings for me (it was taken Monday, October 20th). Now, here is a screenshot from today, after starting out with 100% this morning:
    As you can see, it's quite a huge difference. The weird thing is that messaging seems to take up more battery life than it used to. Yes, I do text quite a bit during the day but the frequency of this has not changed between now and October 20th. It shouldn't be using THAT much battery life. I took it to the Genius Bar yesterday to ask them about this problem and the girl told me that she saw some crashing from the Messages app in Diagnostics Information and she felt that maybe since the update, there was something causing that app to use more battery. So she suggested erasing the phone and restoring from an iCloud backup. I did this yesterday when I got home but, as you can see, the problem is no better (though there are no more crashes listed in the diagnostics information).
    I have no idea what else I can do to fix this and I'm getting really tired of having to charge this twice a day now (I used to have to do this with my iPhone 5, as well). If anyone has had a similar problem, I would appreciate suggestions. And before you ask, I'm doing all of the normal battery saving tricks, like turning off background app refresh, not having it check for mail all the time (it's manual), brightness is down, I turn wifi off when not using it, I don't leave apps open, etc etc etc.
    Any help would be appreciated. Thanks in advance!!!
    Pooja

    I turn off background refresh, mail push/fetch, and I turn off wifi and bluetooth if I'm not using them. I also minimize which apps use location services. Even when doing all of that though, the battery life became terrible on 8.1. Since updating to 8.1.1 all issues seem to have been fixed so I'm very grateful for that. I recommend anyone on 8.1 who is having issues to upgrade to 8.1.1 immediately.

  • HT4061 my iphone 4 battery went dead then when i went to charge it the plug into itunes came up as its gone into recovery for some reason, itunes is only giving me the option to restore which i dont want to do as i have photos of my babys !! help me !!

    please help!! my iphone 4 battery died then when i tried to charge it the plug into itunes came up as my phone has gone into recovery mode for some stupid reason! i have tried tinyumbrella as itunes is giving me no other option but to restore, i dont want to restore as i have very important photos of my babies that i havnt backed up yet and CANT loose!! iv tried holding the 2 buttons intogether but that doesnt work either ! there is bound to be a way around this without loosing my photos. im tamping with apple, this shouldnt happen ! aswell as worring bout loosing all my photos and now i have no phone so am paying for a contract that doesnt even work . please please please helppppppp ! x

    If your phone is in recovery mode, all the data on it, including those photos, is already lost.  Leaving important photos on a phone for any length of time, such as baby pictures, as you've found out is a terrible idea.
    You've no option but to restore your phone.

  • Solved my iPhone 5 Battery Problems: Maybe it can help you!

    Hi every one, I saw many topics regarding battery problems with the iPhone 5. I responded to one discussion describing what I did to solve the iPhone 5 battery dying fast on me. So I thought I'd make a discussion here to help out other users with the same problem.
    I would have 25-30% drop with in the hour and all I did was text a couple of my friends. I was using an iPhone 4 for the longest time, and on that phone I was able to watch videos, listen to music and use all the other features of the phone. The battery still lasted me the whole day, I was getting  worried that I wouldn't be able to use the iPhone 5 the same with out it dying on me fast.
    My friend suggested draining the battery and then charging the phone to see if any improvements were seen. I did that and I saw a small change in the battery strength. I drained the battery two more times, and that is when I saw a huge difference.
    I use my Phone as my iPod when I work out, and I run continuous music on it for 1.5-2 hours straight, along with sending texts to my friends. In this duration I would only use 15-20% which was a huge improvement from before. I would say that the battery life was on par with my iPhone 4 battery! It is such a relief, now I can use my iPhone 5 to it's fullest potential without having to worry it'll die on me fast.
    I recommend other iPhone 5 users try draining their batteries a couple of times before charging as well if they are experiencing problems.
    Hope this helps!
    Dylan

    I would let the battery completely die before I would charge it again. I would keep 3g off and only turn it on if I'm going to use it and turn it off again. Because the phone uses more power for the 3g/4g that the battery dies even faster.
    I text a lot to friends so I'm constantly texting through out the day and when I work out continously run music on it for close to 2hours. It would only drain 15-20% of the battery, which really is a huge improvement.
    I also use Siri quite often through wifi and it barely uses any battery power. Try letting the phone die until it turns off a couple of times before you charge it. That is what I did before a friend requested doing that after I was getting fraustrated with the battery power.

  • IPhone 5 Battery is a Bust and the Fixes Won't Help

    You can setup your new iPhone 5 as a new phone, and it's not going to solve the problem of battery drain. I tried both ways. First, I restored by 3Gs backup to the new iPhone 5, and then I wiped the new iPhone 5 and set it up as a new phone. There are alot of claims that this will make a substantial difference. It may have made a small difference, but in the larger context it makes none and here's why:
    The iPhone 5 battery does not perform even close to the specs claimed by Apple. There is no way you will get 225 hours of standby time. There is no way you will get 10 hours of Wi-Fi time.
    Specs: http://www.apple.com/iphone/specs.html
    I could put my new iPhone 5 into Airplane mode, then turn Wi-Fi on and have everything else turned off: Siri, Location, Nofitications, Push. At best, I might get 6 hours of surfing time. No video, just apps and web pages.
    I doubt very much iPhone 5 can even last a single work day of telephone calls, email, and web surfing. And this would be even if LTE, and everything else is turned off: Siri, Location, Nofitications, Push.
    Latest Usage Data, with no LTE, Siri, Location, Nofitications, Push. In fact, the stats below are with 1 short phone call, and in Airplane mode overnight. Usage must stand for any time the phone is simply not asleep, certainly not when an app is being used.
    Battery: 9%
    Usage: 6 hours, 27 minutes
    Standby: 1 Day, 5 hours.
    My conclusion: Apple's battery specs are not even close to performance. I really don't see how one could use the iPhone 5 as a business phone, as it could not even get you through a 12 hour day. And by 12 hour day, I mean ALOT of time when the phone is is in standby mode.

    did you have a technical question?

  • 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.

    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.
