IPhone 6 Plus battery life seems to drop non-linearly

I'm not sure it's a problem yet or not, but I've been watching the battery life over this first day of use, and it is very non linear, even though use has been pretty linear.
For example, after the battery indicator dropped to 90% usage I calculated out how much the battery life would be at that rate and got like 19 hours!
But at 80% usage it dropped to 13 hours.
And so on... subsequent calculations have it multiplying out to 12.5 hrs, 12.3 hrs, 11.2 hours , 9.3 hours and now at 55% battery it multiplies out to 9.2 hrs.
I wonder why the more time passes the remaining percentage seems to drop at an accelerated, rather than a linear rate. Anybody have any ideas?
Thanks,
doug

The rate of battery loss is still slowly accelerating. At this rate I expect less than 8 hours usage time.
I wrote a review of my new iPhone 6 Plus here and brought up the issue:

If anybody has any ideas, or comparative battery life results, please let me know.
Thanks,

  • IPhone 4S Battery Life: Best solutions and procedures for 1st time user: 1-Do you have a battery life issue (learn first what the usage time spec is about) 2-What can you try to remedy the situation without reading 500 pages of posts

    What follows is a grouping of some of the most fruitful procedures - from what I've seen in the biggest battery life issue thread - and some background information and discussion for solving or improving the battery life with the iPhone 4S and may be applicable also to devices on which iOS 5.0/5.0.1 has been applied. Credit goes to the respective users who contributed this information to the forum and they should be commended for doing so. This is not a final listing. The goal here is to provide a first stop sort of knowledge base document for newcomers instead of having them perusing the never ending threads where the wheel is reinvented on every page...
    Please don't post your questions, usage screenshots, or claims that it worked or not for you or anything here except PROCEDURES/DEBUG STEPS/SOLUTIONS or improvements to the procedures already listed here. Try to use point form and to be as concise and clear as possible. Hope all this helps.
    Thank you and good luck!
    General info and specs
    First, take a look Apple's battery tips, info and specs(obligatory reading for all Iphone 4S users - read it once and for all):
    http://www.apple.com/batteries/iphone.html
    http://www.apple.com/batteries/
    ... you didn't read it? loll Always remember this i.e. the definition of "usage":
    Usage: Amount of time iPhone has been awake and in use since the last full charge.  The phone 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.
    I'm still not convinced you read the links so here's what Apple has to say in terms of fine tuning your battery life:
    Optimize your settings
    Depending on how they are configured, a few features may decrease your iPhone battery life.  For example, the frequency with which you retrieve email and the number of email accounts you auto-check can both affect battery life. The tips below apply to an iPhone running iOS 5.0 or later and may help extend your battery life.
    Minimize use of location services: Applications that actively use location services such as Maps may reduce battery life. To disable location services, go to Settings > General > Location Services or use location services only when needed.
    Turn off push notifications: Some applications from the App Store use the Apple Push Notification service to alert you of new data. Applications that extensively rely on push notifications (such as instant messaging applications) may impact battery life. To disable push notifications, go to Settings > Notifications and set Notifications to Off. Note that this does not prevent new data from being received when the application is opened. Also, the Notifications setting will not be visible if you do not have any applications installed that support push notifications.
    Fetch new data less frequently: Applications such as Mail can be set to fetch data wirelessly at specific intervals.  The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose 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 that this is a global setting and applies to all applications that do not support push services.
    Turn off push mail: If you have a push mail account such as Yahoo! or Microsoft Exchange, turn off push when you don’t need it. Go to Settings > Mail, Contacts, Calendars > Fetch New Data and 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.
    Auto-check fewer email accounts: You can save power by checking fewer email accounts. This can be accomplished by turning off an email account or by deleting it. To turn off an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and set Account to Off. To remove an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and tap Delete Account.
    Turn off Wi-Fi: If you rarely use Wi-Fi, you can turn it off to save power. Go to Settings > Wi-Fi and set Wi-Fi to Off. Note that if you frequently use your iPhone to browse the web, battery life may be improved by using Wi-Fi instead of cellular data networks.
    Turn off Bluetooth: If you rarely use a Bluetooth headset or car kit, you can turn off Bluetooth to save power.  Go to Settings > General > Bluetooth and set Bluetooth to Off.
    Use Airplane Mode in low- or no-coverage areas: Because your iPhone always tries to maintain a connection with the cellular network, it may use more power in low- or no-coverage areas.  Turning on Airplane Mode can increase battery life in these situations; however, you will be unable to make or receive calls.  To turn on Airplane Mode, go to Settings and set Airplane Mode to On.
    Adjust brightness: Dimming the screen is another way to extend battery life.  Go to Settings > Brightness and drag the slider to the left to lower the default screen brightness. In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions.  Go to Settings > Brightness and set Auto-Brightness to On.
    Turn off EQ: Applying an equalizer setting to song playback on your iPhone can decrease battery life.  To turn EQ off, go to Settings > iPod > EQ and tap Off. Note that if you’ve added EQ to songs directly in iTunes, you’ll need to set EQ on iPhone to Flat in order to have the same effect as Off because iPhone keeps your iTunes settings intact.  Go to Settings > iPod > EQ and tap Flat.
    Usage specs for the 4S - http://www.apple.com/iphone/specs.html:
    Talk time: Up to 8 hours (12.5% per hour drain) on 3G, up to 14 hours (7.1% per hour drain) on 2G (GSM)
    Standby time: Up to 200 hours (0.5% per hour drain)
    Internet use: Up to 6 hours on 3G (16.6% per hour drain), up to 9 hours (11.1% per hour drain) on Wi-Fi
    Video playback: Up to 10 hours (10% per hour drain)
    Audio playback: Up to 40 hours (2.5% per hour drain)
    So a scenario of normal usage could be for example: 4 heavy hours of 3G internet browsing (66.4%), with one hour of call on 3G (12.5%) and 22 hours of standby (11%) = 100%
    A battery life issue is a problem where the drain is really out of spec either during usage or standby or both. For example, multi-% per minute drain during usage or a 10% drain per hour during standby is problematic. Browsing the internet on 3G during one hour and losing 16-17% is not.

    davidch tips (reset+full discharge recharge):
    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). 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  (tilll 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. 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!

    6. Disable Siri 'Raise To Speak' and REBOOT *( if possible use another camera to verify the                 infrared is off after the reboot).
    7. Set emails, icloud and calendars to fetch. ** test. Mines on hourly.
    8. If your in a no signal and your phone is saying "Searching..." even after 10mins, reboot while in that area and after 1-2min it should say "No Service". This mainly applies to Verizon customers and improve battery life in these areas.
    9. *optional* Goto Settings > General > Network and you will see "Hotspot.." loading something, wait a few seconds and it should say "setup personal hotspot" then exit out.
    * I notice a great improvement after disabling this and rebooting. This increased my "screen on" usage or at least helped it. Make the change.
    ** I have not tested push yet to narrow down the drain but I had this change on my phone. I believe exchange push is responsible for some stand by drain. As for icloud, haven't notice much of a difference. Just try it for a day. My email still came in fast most times. Again still testing, will report back on these..
    buxbuster tips(wifi sync, iCloud):
    These are my own tested workarounds that worked for my iPhone 4S and seemed to have worked for others as well :
    Workaround number 1. Deselect wifi-sync in iTunes and press sync.
    If that doesn't work try :
    Workaround number 2 : Remove iCloud, reset network settings. ( I guess this won't work for you since you don't have it enabled ).
    If both workarounds fail, you can always try to completely wipe your phone. That also solved some of the cases out there.
    rolandomerida tips - i.e. buxbuster and additional steps:
    Finally, I solved the syncing error loop. My contacts are syncing flawessly again between my devices and iCloud, and yes, the battery stopped draining, which is the main topic here.
    I followed instructions from buxbuster (check his workaround a few pages up!) and an additional BIG step to restore contacts and syncing, as seen in a MacRumors forum.
    This is what I did:
    1. Make a backup of your Address Book, using the vCard option (or both, it doesn't hurt). Save it for later.
    2. In your iPhone, delete iCloud account. When it asks, accept both: delete AND delete from my iPhone.
    3. Reset network settings. The iPhone will restart, then will ask you to unlock the SIM card.
    4.Turn Wi-Fi on.
    5. Add the iCloud account again.
    That's for Buxbuster's workaround. For some, it might work just like that. My iPhone repopulated from iCloud after step 5, but I still had that "server error" on iCloud. I had to do some extra steps, since my Mac was not syncing to iCloud and couldn't edit anything on my Mac or iCloud. Syncing back had to be fixed, too. If not, the syncing loop would continue from my iPhone, and the battery would drain awfully again.
    1. In System Preferences -> iCloud, I turned Contacts off. I chose "keep on My Mac" those contacts, but I got an empty Address Book after a while. And a few minutes later, iCloud contacts were empty and my iPhone also. It is scary at first! Now, before importing that vCard backup...
    2. Turn Wi-Fi off. This is important, since your contact-empty iCloud will attempt to wipe your Address Book from your Mac in seconds after importing.
    3. Import your vCard backup to Address Book. Just drag it to your blank Address Book window; it asks if you want to import "x" number of cards. Of course, say yes.
    4. Turn Wi-Fi on, and then iCloud contacts on again (System Preferences -> iCloud). It will offer to merge your newly populated Address Book with iCloud (which is empty at this point). It should upload every single contact to iCloud, and then to your iDevices. If not, a fifth step would be to import the vCard file to iCloud, but it shouldn't be necessary.
    So, with iCloud syncing working correctly, there is no battery draining! Again, that was my particular issue.
    I can't tell if this is the single answer to the widely spread battery draining problem, but it sure can be fixed with these workarounds, and yes, Apple should address the problem with a future update, for we affected customers don't need workarounds in the first place
    This is the MacRumors discussion:

    Miless tips (full 800mb release of 5.0.1 and sanitizing a restore):
    As for 4S battery life. Try doing this,
    1. Settings>Location Service ... disable all location services you do not need. In particularly Facebook because it drains the battery a lot.
    Scroll down to the bottom at Settings>Location services>System Services ... Disable Setting Time zone, location based iAds, Diagnostic & Usage.
    2. Settings>Notification>Calendar ... turn off the Notification Centre.
    3. Settings>General>Reset ... do Reset All Settings. Doing this will not wipe out your iPhone. It will just Reset the network settings, location warning, keyboard dictionary, etc... but it will clear up some corrupted data there. Generally this will help.
    Try these 3 steps first... if it still drains a lot, try the following,
    4. Drain your battery down to 1%. Then charge it up using USB from PC ... not the charger. The charger output 1.0 A ( x 5V from USB ... you get 5W power). From PC, output is only 0.5A x 5V = 2.5W power. Charging is slower but trickle charge 4S helps the battery retain its charge better. I think it takes about 3-3.5 hours to charge full from USB/PC compared to slightly below 2 hours using iPhone charger.
    If after doing the above still could not solve your battery issues (mine with iOS 5.0 was ok up to step 4, but not iOS 5.0.1).... plug you iPhone to a charger (any charger), from iPhone, access your iCloud ... set it up if you havent. Back up your iPhone data to iCloud. if you do not have enough storage (only 5GB is free), go to details and select the apps you need its data backup, choose only those you really need and leave those unnecessary ones out. Back up your camera roll to your PC/Mac manually as it could be too big to backup to iCloud.... once you have it setup, make sure you are on Wifi ...  tap backup to iCloud from your iPhone. It will take a while if the file is huge.
    Once backup to iCloud is completed, plug your iPhone to PC/Mac and launch iTunes 10.5.1 (make sure you have 10.5.1)
    Click Restore. It will automatically initiate a download of iOS 5.0.1 ipsw for iPhone 4S. Wait for the whole process to finish, ie. download, restore software/firmware.
    Once its done, do not set up your iPhone from iTunes. Set it up on your iPhone. Go through the selection. When prompted, select restore from iCloud (from your iphone backup earlier). Keep your iphone plugged into iTunes while restoring backup from iCloud. Because while restoring from iClouds, some data will be synced from iTunes if you plug in, e.g. music, video, etc... unless you bought these content from iTunes store. Apps will be downloaded from App Store from the cloud.
    Once it's all done restored. Turn off your iPhone,.. and turn it on again.
    Now, hopefully your battery wont be draining so fast anymore. Usually it wont after this. But you need to charge your battery at least 4-5 cycles to stabilize the charge on the battery. I dont know why... but battery life seems to get better and better for me after a few charge cycles after all the above work.
    Good luck. Let us know if it works for you.
    W. Raider tips (Sirii):
    Bottom line for me of things that helped battery life are:
    1. Turing off Siri and Rebooting the phone by holding the Home button and Top button down, ignoring the slider, until the phone shut down. (turn off Siri, reboot, and check top front of iPhone 4S against a lesser camera like the front-facing camera on an iPad2 - making sure the IR sensor is off)
    2. Fully draining the battery, meaning using the phone until it shuts itself off from a drained battery and then recharging it to 100% about 4, maybe 5 times. I charged it both with a Mac and a wall charger.
    Hope this is helpful!

    jmm514 remarks (Twitter):
    I may have found something. I had Twitter disabled in my notifications, but got a tweet today that popped up on my home screen. Didn't know I had this enabled. At the bottom of the Twitter notification settings is the home scrren toggle. Since disabling this, battery life seems better. Considering there is no setting for frequency of checking for tweets, it appears the phone is continually connecting to wifi to check for new tweets.
    tmksnyder comments (notifications, corrupt data in iCloud):
    For me, I found my iphone on wifi mysteriously connecting to my mac.  I eventually narrowed it down to the Apple Move Trailers app which keeps a file in iCloud.  The phone was trying to sync the file with the mac in the background even when the Movie Trailers app was closed (hitting the red x).  Based on my macosx logs the iCloud process that was trying to sync was working directly between the phone and the mac without using itunes by connecting to an https address hosted on the phone.  It was connecting every 3 minutes and failing (while phone was awake or awake during during a notification).  I also found that iCloud control panel on OSX would error if I tried to delete the file.  I fixed it by removing the App and doing a hard reset which stopped the sync.  I probably could have turned off iCloud document sync in the phone but didn't think of that.  My battery life has greatly improved while at home on wifi.    I am now at 28 hrs standby, 2 hrs 20 minutes of usage, and 68% battery.  It was ok before where I could get 20-30 hrs standby and 6 -8 hrs usage.  My usage today was phone calls, 3g surfing, and music via bluetooth in the car.
    I also found even with Itunes iMatch, if I mass updated tages, art work etc, it would hit the phone on wifi even in standby.  I was amazed.   Granted if I am not doing updates, Match won't hot the phone so this was a once in awhile event.  I could drop my percentage by 5-10% in a matter of minutes when doing updates.   I think a lot of our problems are background processes, associated with iCloud, notification, and apps.  More features means more battery.   I think the key thing is to keep track of what has recently been added or changed if battery life gets worse all of a sudden.   It may be an app that was recently installed and if possible you may want to completely remove it and not just quit it.
    With twitter, i think it uses push notifications so it doesn't need to be running and actively poll on the phone. For instance , if i quit the mail app, i still will get mail notifications and can swipe the message and load mail. Apple Push Notifications servics maintain the connection to the phone and there are likely pings or connection checks  that occur for the service on an os level not an app level.  This minimizes the load so there arent a bunch of apps all runing and constantly checking.  The notification service , if it is contacted from twitter or another service with data, will check the settings you have registered to the with the apple push service and send the notification to your phone.  No matter what, there is a drain with notifications. M hunch is once one application is configured to receive notifications, connection checking occurs betwen the push service and the phone so it knows where it is on the network. If it is implemented correctly, these checks arent frequent if you are still and more frequent as you move. The other drain is for when the noification hits and is processsed.  If i get 9 emails over night, my screen just popped up for 20 seconds or so to process each message using battery.  I would even think that just go from low power to turning n the screen uses more juice than if the device was already on and i get the message.  On nights I get no notifications, I see a 3  or 4 percent drop.  On nights with a number of notifications, i have seen up to a 10 percent drop.  Besides notifications, wifi sync and icloud will poll on the local network and use up battery if the host computer is on and running itunes or trying to sync a data file that is corrupt (which i had with the apple movie trailers app causing my phone to drain).  For me turning off wifi sync and remving a corrupt file in icloud solved my battery issues and I get over 24 hrs of standby with 6 to 9 hrs of use and this is with all the normal location services and push serivices turned on.
    See http://developer.apple.com/library/mac/ipad/#documentation/NetworkingInternet/Co nceptual/RemoteNotificationsPG/ApplePushService/ApplePushService.html for more info.  I think it has a good overview of how the notifications work.

    Well seems like that rumor of iOS 5.0.1 is finally gone the way of the dogs since developers got a beta of 5.1. So as stated earlier in the master discussion-> I suspect if you are filling up this thread with false post or creating a master set of links to various post that are unreliable you are wasting your time. Press is not going to touch the story due to poor or inaccurate sources which may be links from the master thread. This can include inaccurate information, combination of conflicting post or postings from users which may not own the device. Reputable press organizations have policies that require discloser and strict rules about what is a reliable source for a story. It is clear that many of the post in the master thread, which are links presented here are questionable. 
    Sorry to say that postings taken without any analysis of their totality have been propagated via various sites, for example sites such as http://www.2012federalbudget(dot)com. (Do not visit but I suspect that this is not the 2012 federal-budget site you would expect based on analysis of the records. There are plenty of sites like http://www.2012federalbudget(dot)com propagating questionable post in these threads.) One site for example in the discussion thread used a self signed certificate, the site had a log in to allow users to enter their OpenID. Seems many of these sites are pop and drop drupel configurations.
    So remember this is how the really bad rumor of iOS 5.0.2 got started, the 5.1 memory leak issue, iCloud Issues, call quality, address book, etc.
    Some of the postings have been very comical, I think the latest now is a dropbox issue. Seems that the length of the previous thread has resulted in various app engines of some proxy servers/tools reaching their limits.
    So I would make sure to know the source of any information you link to. Make sure you avoid entering any information to outside links such as OpenID or Apple ID, these are big prize items for anyone with malicious intent.  If you have issues and are a valid user contact APPLE CARE. (Note link is using McAfee Secure Short URL Service, and is https.)
    http://mcaf.ee/ricdt
    The original solution still represents a high level of success for users having any battery issues.
    Install 5.0.1 on your iPhone 4s. Some users posting they are still using older versions, bad fake serial numbers, etc.
    Make sure your device can run iOS 5.0.1 and is not altered.
    Make sure you use a new Sim, not some cut down version which many users admit to doing. (Again, worth confirming what people are posting.)
    Reset the device doing a hard reset and software reset.
    Let battery drain and then charge for the full cycle, which is 24 hours.
    I think you will find you will get the battery usage that APPLE has stated for the device.
    Best of luck, stay safe and thanks

  • 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.

  • Want to increase iPhone parts battery life

    Hi..Friends i want to increase my iphone parts battery life ..Please share some tips with me...

    Hmm.....
    the phone is solid state.... there's hardly any parts to wear out.
    I guess you avoid pressing the home button?  Carry a bluetooth keyboard?
    the old phone connector can wear out, but I hear the lightning connector is improved.  You do need to charge the phone regularly and you need to have it disconnected when the phone is away from the charger
    avoid water or moisture.  Potentially a problem in humid climates and having the phone in your pocket
    avoid drops or impact that can crack the screen or dent the case?
    perhaps a "bumper" or case to keep away scratches?

  • Does anyone know what's up with the iPhone 4s' battery life? Some days it last a long time and other days it drains extremely fast.

    Does anyone know what's up with the iPhone 4s' battery life? Some days it last a long time and other days it drains extremely fast.

    Not to point out the obvious, but battery life depends very much on what is running and how much the device is being used.
    If the battery lasts longer on a day you make no phone calls, but lasts less the day you make 5 hour long calls, this is to be expected.
    If however the iPhone has the same level of use on both days, with different power consumption, this would infer a background process (or App) is trying to do something (connecting to server or creating a back up etc).
    I switched off all thrid party apps from being included in my iCloud backup, which saves a huge amount of space on the cloud and allows the back up to take barely a couple of minutes.
    Battery life seems ok so far on my 64GB 4S (Bluetooth on, Wi-Fi on, Location Services on, Push notifications on, Screen set to just under half brightness with Auto Adjust on)

    ok, I will tkae that under consideration. Now I have another battery issue, after fully charging the MP3 player I noticed that the battery life drain rather quickly while it is off. I lost 9% of it's charge from taking it off the charger at midnight and then plugging it into the usb port of my computer the next morning at 10:00am. The clock is turned off so it should not be doing anything for those 0 hours.

  • Where is this magical iPhone 6 Plus battery life?

    iPhone 6 Plus users, are you getting the great battery life that most reviewers and reporters are describing with the iPhone 6 plus? I've had mine for two weeks, and while I wouldn't say the battery life is bad exactly, it hasn't been the stellar improvement overall compared to my old iPhone 5 that reports have led me to expect. Many people seem to indicate you can go a day and a half or two days with moderate usage without recharging, and I am lucky to make it to the end of the day and not get a low battery warning.
    I've fiddled with settings (background app refresh, push e-mail, deleting Facebook app altogether, turning off Pebble/bluetooth, etc.) and while it may make some difference around the edges, I'm certainly not finding that I have more than 50% battery left at the end of a day of standard usage, like some people are saying. My usage isn't light, but it certainly isn't heavy, either. I'm not watching a lot of video or playing many video games or anything during the work day. I'm probably actively looking at the screen for maybe a total of 3 hours a day.
    Are my expectations too high? Do I have a substandard battery? I am willing to change settings, but at the same time, a great part of the appeal of the 6 plus for me was not having to do that battery dance all the time. Any ideas?

    my iphone 6 plus is by far the absolute worst battery life of any phone i've ever owned. I brought my phone into apple store genius bar and showed them like 50 screen shots of my battery usage screen saying i lost like 50% over the course of a few hours of extremely light use. They basically told me "our battery diagnostic app says yur battery is fine... go away.'
    I've tried that let it die down to zero percent and then recharge thing like twice. It does nothing. Apple refuses to acknowledge that my iphone6 plus has a garbage battery. I do not trust their battery diagnostics test as far as i can throw this 1000 dollar paperweight and that is basically what this phone has been since the second i owned it,
    THis is NOT A TROLL post. I am a 100% genuine iphone 6 plus owner who truly is unsatisfied with my purchase.  This is truly 100% without a shadow of a doubt the worst battery ive ever seen on any smartphone ever and at the same time i acknowledge that there exists ip6+s with great battery life. There has to be some super dodgey stuff going on like there are just tooooo many bad batches or something. Maybe my phone was part of some rushed batch to make it in time for christmas and they were careless n heavy handed at the factory something i dunno but what i do know is my iphone 6 plus has absolutely dismal, pathetic and downright makes the phone unusable when i am out and about due to battery anxiety.
    There are way too many posts of people saying their ip6 battery is bad while other posts saying it's good. It's starting to become apparent that the iphone 6 is just extremely inconsistent and quite frankly not worth the risk really. You could get lucky n get a good 1 but you could very well get 1 like i have that literally died down from a full 100% charge down to fully dead in less than a half a day from literally zero use whatsoever. it just sat there sleeping. I didn't use it during this. It was a test to see how long it would take to die and it failed this test miserably and yet apple's useless little battery diagnostic over at genius says my battery is just fine n dandy... yeah right. Its crap. The genius dood who was totally cool n he's just doing his job/ protocol or whatever no knock to him but he just pointed me to some battery conversation tip link on apple's website and sent me on my way. I showed him screenshot after screenshot showing extremely poor battery life math and he just wasn't interested in hearing of any of it cause his all knowing battery diagnostic thingy infront of him is some all knowing crystal ball says my battery is fine and that's the end of it and the piles of screenshots i have saying my battery is dying 10 times faster than your are claiming while i had no background apps or anything whatsoever running don't mean a thing.
    I want my money back apple . Your product does not perform as advertised. 

  • IPhone 6 plus battery life

    I had played Vainglory for just 3 hour and the battery life is 10% left, is this normal to iPhone 6 plus? I used my home wifi.

    Yes!  You can't expect miracles even from modern batteries.  You gave the iPhone 6 processor and display a heavy workout.  The fact that it lasted 3 hours seems great to me.
    If you have not already, you really should look through every single Setting screen on your phone and see what services you do not actually use and disable them.  Nearly everyone can benefit from learning what is available in Settings and configuring the phone to balance needed services with functionality, battery life, and privacy.
    Have fun with your iPhone 6.  Wish I had one.

  • 6.0.1 seems to have fixed my iPhone 5 battery life. Hypothesis as to why inside...

    So after installing iOS 6.0.1, and being COMPLETELY angry with no mention of the battery drain glitch being resolved in the patch notes, I'm pleasantly surprised that I can report that my battery life is now BETTER than my iPhone 4 was. This is like a godsend! I used to see a percentage go down in less than a minute, but I've been at 94% for the past 5 minutes of usage at max brightness with all settings on like cloud, fetch, push, etc.
    My best guess as to the glitch that caused the battery drain is that something was entirely funky with the way wifi and cellular was handled, and that was the glitch that was resolved that indirectly was causing diminished battery life.
    I assume that Apple was aware of the glitch, but wanted to minimize bad publicity so they never acknowledged the problem, but worked on a fix silently. I'm not sure I agree with that approach, but the important thing is that they seemed to have fixed it, since the difference is so obvious to me that it's like night and day. Can anybody else confirm their battery life has also improved significantly?

    I've been using my phone constantly for the past half hour with all features on and max brightness and its only gone down 5%.
    It was going down over a percent a minute before with features turned off! It's so dramatic that it's hard not to notice.

  • IOS 8.3 is draining my iPhone 6 Plus battery life. how to downgrade to iOS 8.2?

    I never changed my mobile phone using habits. All that changed recently is my iPhone 6 Plus getting an iOS 8.3 update. I noticed my battery life draining quicker than the usual. It used to still have enough juice to last me until midnight, now by lunch time i am already at 63%!
    Anyone experiencing this?
    Know the proper legitimate way to downgrade from iOS 8.3 to 8.2? Prefer to have longer battery life than have this updated 8.3 in my phone. I don't feel the benefits of the upgrade to begin with.

    The rate of battery loss is still slowly accelerating. At this rate I expect less than 8 hours usage time.
    I wrote a review of my new iPhone 6 Plus here and brought up the issue:

    If anybody has any ideas, or comparative battery life results, please let me know.

  • Awesome iPhone 6 Plus battery life

    So, this isn't really a question but a comment: I'm not sure if the battery life has improved even more after that last iOS update, but my 6+ gets some awe-inspiring battery life: I had recharged the phone Sunday night a week ago, and as of right now, six days and about five hours later, I'm at 4% battery left. Now, granted, I didn't use the phone all that much, but I did stream music for one to two hours every day (Pandora, then to the Bluetooth in my car), checked email, a couple of phone calls, a few text messages, etc., pretty much typical usage for me when I'm in my office. Even considering my failry light usage, I think a full week of battery life for a modern smartphone isn't bad at all...
    That's all, just wanted to say something nice about Apple for a change... ;-)

    It's so nice to see people saying nice things about Apple products. I was able to get 12 hours of battery life with heavy use on my iPhone 6 yesterday. The battery life on iOS products is indeed nice!

  • Brand new iPhone 6 battery life dropping very fast and charging even faster

    my brand new iPhone 6 that I have just recently started using the day before has a surprisingly bad battery life. whrn first turning on the phone to use the battery life only last 1-2 hours with average use. when the battery died this morning I pluhe'd the phone into charge and the battery is charging very fast already at 25% and only being charging for about 15-20 mins. I would like to know if anyone else has experienced this problem and if it is normal or if I have just recieved a faulty iPhone 6?

    Can you check:
    1. What apps show on settings - general - usage - battery usage?
    2. How many apps have permission to use cellular data?

  • Can someone at Apple please help me with iPhone 4s battery life?

    I bought two iphone 4s 16gig's the day they were released from Sprint and am having horrible battery life. I love the phone and its features, but I have tried everything I have found in the discussion groups and in other forums online and am still getting terrible battery life from the 4s's.
    For example, I charged my 4s when I got home last night and then once it was at 100% charge at bedtime, took it off my charger in order to use that same charger to charge my ipad overnight. This morning, the fully charged 4s had dropped to 45% battery life...without ANY use whatsover overnight...! I just asked my wife how her 4s is doing today and hers is down to 63% since this morning with very, very little usage. (She hardly ever uses any of the data features, etc., only makes phone calls).
    Something really weird also happened to the battery life yesterday while I was flying home from Venezuela. I had charged my phone overnight and did not use it at all on the way to the airport, then turned it off on the plane from Maracaibo to Miami. When I arrived in Miami, I turned it on, checked my email, sent a few text messages and also some Heytell messages during my 1:45 minute layover before turning it off before getting on the plane. Our flight was delayed due to mechanical problems and I turned the phone one in order to show my seat mates how Siri works. When I turned it on, I was shocked to find the battery percentage had dropped to sixty some percent...!
    I left T-Mobile after 8+ years as a very satisfied customer specifically to get the new 4s. Was running jailbroken 3gs on T-Mobile without any problem and much, much better battery life. Needless to say, I am very unhappy with what we are dealing with. I wish someone from Apple would at least tell us what is going on or simply replace our phones if it is a hardware issue.

    You need to check out some of the other threads on battery issues (but not the very long one) in this forum.  There are a lot of suggestions from users who seems to solved the problem.
    But you won't get any Apple input here, as this is a user-to-user forum and Apple usually doesn't respond to out posts.
