Incorrect Daily Usage (Battery issue?)

Hi all,
As an update to the discussions about batteries, first the brief background: I have been a long-time PDA user, and am used to poor battery life. My iPhone 2G, under moderate use, would last about 2 days. Heavy use 1 day. I expected the 3G to get as bad as 1/2 that.
Yesterday I used the phone for my drive in, then holstered it at the office, taking it out to update my calendar 2x. By 4pm my battery was dead.
I had reset the usage statistics, and discovered that the iPhone reported 1 hour talk time (correct) and nearly 4 hours of "Use" (only use should have been the talk time plus the 5 minutes of calendar updates), and 7 hours of standby.
It seems to me that this battery life issue (at least in my case) is more likely a software (process running that should not) rather than hardware (damaged battery/evil Apple) problem. However, I have no clue what could be running.
I ran a full restore last night (reset all settings manually -- did not restore from my backup), and shut off location services. We'll see if it helps, and if the usage stats are now correct. In the meantime, if anyone else has any ideas as to the problem, they would be appreciated.

I found this solution:
1. Delete all email accounts
2. Select "Reset Network Settings" from Settings -> General -> Reset
3. Select "Reset All Settings" from Settings -> General -> Reset
Yes you are obviously going to lose your email setups and network settings - you will NOT lose the Photos, Calendar, or iPod songs. If you select "Erase All Content and Settings" you will lose everything - be careful.
After the phone reboots - setup your email accounts and input your network settings.
I was told by a Genius at the Apple store that if you leave "Enable 3g" on, Location Services On, Fetch New Data to Push, it's going to use up the battery quickly.
As of yesterday morning, I have 3G On and Location Services On, and at the time of this post the battery is only down about 1/4. I have not turn on Fetch New Data - In my case I have no reason to have my phone set to on.
I am not a heavy user of the phone, but before I did the above, my battery was lasting 3 - 4 hours when I was not using the phone.
This also corrected the Daily Usage issue.
Hopefully, this will help someone out there!

  • 5.0.1 update - battery issue - check usage/standby stats

    There might be more than one problem but i did find mine and fix it.  Check your usage and standby in general settings and if they are the same, then you have the same problem I had (they should not be the same).  If they are the same, that means your phone is never going in standby mode.  I fixed the problem with a complete reload.  I did not choose to restore from backup because I wanted to be %100 sure it was a fresh load of the software, so I setup as a new iphone.
    Background: I upgraded from v4 to v5.0.1 a few days ago and started having battery issues.  I went to the apple store and they did some diag test on my phone/battery and said everything checks out good.  They said my options were to buy a new battery or drain my existing batter to zero, let it set for two hours, then recharge to %100 again and see if it fixes my problem (it did not). The person at the apple store ask me if that sounded like a good plan, I said no, not really (does not make much sense), Im not buying a new battery, especially since you said mine checks out good, but i will try the recharge and see what happens.  So, I was back to square one and then a friend told me about the usage/standy thing. Maybe this is a bug in the software when you do the upgrade (or at least for me) and v5.0.1 works fine from a fresh install.  My phone battery is working great now.  Looking at my usage stats now, I have 1 hour, 19 minutes usage and 3 hours, 17 minutes standby, and %90 battery.

    Glad that a Restore as New resolved your issue...

  • A suggestion for those with battery issues:

    When I first got my iPhone, I had the same battery issues many people here are talking about, in fact I posted about it myself. Its fixed. Very fixed, and Im very happy with my battery life. Here is what I did.
    First, do not charge it using your USB connection. At least not always. Why? I dont know. I did the first few days, and couldnt get a full charge even tho system wasnt going to sleep. I started using the wall charger, and got longer battery life, but still not great. One night, I forwarded the phone to my home phone in case I got a call, and shut the phone down completely, and put it on charge. In the morning, I woke up to a 100% charged, fully glowing battery icon. The battery lasted all day with no issues. Every night after that, I just charged it on the wall charger, but did NOT shut it down to see what happened. I am still waking up every morning to a 100% fully charged battery. The battery life seems to get better daily now.
    Today, I ran wifi for about 5 hours because I forgot to shut it off. This was after going to the pool and listening to the iPod on the phone for about 2 hours. And using the phone normally throughout the day, checking mail, sms, etc. Really a full day of work, and my battery is still over 50% full. I purposely didnt connect it to anything during the day for a recharge, not the USB or wall charger.
    Good luck, hope this helps. Id be interested to know if it does.

    Here's my non-scientific experiment.
    After surprising battery drain for the first 10 days or so with not much usage, I completely drained the battery yesterday until the phone shut off.
    I plugged into AC charge and was worried when it didn't seem to even begin charging.
    I plugged into USB, assuming it needed to charge enough to at least complete a sync.
    I left it on USB until about 5-10% charge, then switched it to AC. At about 50% I needed to use it, so I did but sparingly, and put it back on charge, all the while keeping Mail on manual and WiFi off.
    I took it off once more to get it home from the office, then plugged into AC.
    I left that charging overnight.
    I never actually got the "glow", but did get the plug icon showing full charge in the status bar.
    After about 2 1/2 hours this morning, the status has not moved off of 100% (but with little usage as before).
    This is definitely an improvement already though. Hope this helps.

  • Genius Bar Feedback on Battery Issues

    Ok..so I know there are hundreds of posts regarding various battery issues. I thought it might be helpful to post feedback on my genius bar visit today regarding my battery.
    The issue with my battery is that the meter seems to be stuck at about 80% full, regardless of how much I use the iPhone or how long I charge it. I have no accurate way of knowing how much battery life I have left. I have even played 6+ hours of straight video to drain the batter and the meter never moves.
    Fortunately, my lightning bolt icon (upper right corner) does eventually change to an a/c plug which tells me that the battery is fully charged even though the big green battery is always at 80%.
    So the guy at the genius bar tried and inquired about all the usual tricks already discussed in this forum (restore, plug AC adapter to wall instead of USB, turn off wifi, bluetooth, etc). and concluded that it's most likely a software issue.
    He did say however that the the usage statistics frequently mentioned here are controlled by AT&T and that it's functionality depends on AT&T sending some sort of over-the-air signal. Don't know if I buy that.
    So, in a nutshell, they did not offer to replace the phone (not that they had any in stock anyway), but instead made a notation of the problem using my serial number and told me to wait for an Apple software update, which will most likely correct the problem. If it doesn't, then they can assume a hardware conflict and issue an replacement.
    I know this is getting long, but I would like to add that my battery life itself seems fine. I just never know what I have left by looking at any of the two meters.

    My original iPhone had poor battery performance and would not reset the usage stats. There is no Apple Store near me, so Apple support sent a service phone and I sent mine in. The service phone has good battery performance and correctly reset the stats. I was notified that the original phone could not be repaired and a new replacement was sent to me. The new iPhone has great battery performance, but no matter what I try, the usage stats won't reset. Today I was told by Apple support that they believe this is a software issue and a revision would be developed to address the problem. There is no forecast availability date. It doesn't make any sense that a signal from AT&T would have anything to do with the battery stats. The service phone charged and reset the stats before I swapped my SIM into it.

  • Semi-Scientific Test on iPhone 4S Battery Issue w/two iPhone 4Ss

    All,
    My wife and I ordered identical 16 GB iPhone 4Ss. They were set up the same way. From the very start, I could tell that her battery was outperforming mine.
    After a day of turning off and on various settings, from Location Services, to Siri, to iTunes settings, etc. I still noticed a huge gap in stand-by performance. I was losing 1% per 10 minutes, her phone was not.
    Today, we had similiar usage with similar network characteristics (WiFi, decent 3G coverage) starting from a full charge (100%). After 8 hours, her phone still had 52% remaining. Mine died on the way home from work.
    So tonight, I performed a test. I plugged both phones up and allowed them to fully charge to 100%. While plugged up, I ensured each setting on the phone were identical, including the number of Exchange accounts, brightness level, etc. At 9pm CDT, I unplugged them. My phone took a long time to get from 99% to 100%, her phone didn't. Mine also went to 99% upon unplug, her's didn't.
    Neither phone was used at all, stayed completely in stand-by mode. At 10:15pm CDT, ...her phone remains at 100%. Mine is now at 92%. That's roughly 1% every 10 minutes on my phone, same thing I saw earlier in the day.
    I think this, for me at least, confirms the diverse results folks are seeing. Some folks are seeing major battery issues, some are seeing better battery life over other iOS devices. It just so happens in our house, we have one of each. Why would two identical phones behave so differently? I've exahusted all possible options on my phone, including the recently posted attempt at deleting e-mail accounts and resetting network settings.
    Does Apple recommend that I do a restore on my phone? I am trying to do so, but I am having issues re-downloading iOS 5. If I still see the same battery drain, I believe I will take this into the Genius bar.
    I do believe it's time that Apple address this battery issue. I for one, based on experience, believe it's real, and could be a manufacturing defect. I don't know how else to explain two identical phones having vastly different stand-by results if my restore fails to fix the issue.

         After spending 2 days troubleshooting I have found my battery drain culprit. When I turn my wifi on it coninuously disconnects and reconnects to my network. This was draining my battery about 1% every 4 minutes. I went through all the turn this stuff off, reset network settings, setup phone as new, helped some but still had the issue. This morning I set mine and my wife's up the same, she went to work and was playing music on the way in. Still had 100% after 40 minutes. I was at home with wifi on and dropped to 90%.
    I charged my battery back up, turned wifi off and now after an hour still have 100%. This is with siri on, icloud on, notifications on, etc.
    Can anyone else confirn this is an issue for them. I am trying to determine if it is hardware or software related.
    Thanks

  • Iphone4s - iMessage, Call & battery issues

    I cannont receive text or picture messages via imesssage every once in a while, it never appears to be an issue when i receive from OTHER phones on other networks. I am able to send the messages though. and this issue is not consistent. it happens every now and then.
    While i was testing this, i also noticed that when i send an iMessage the receiver is seeing my email Id instead of my phone number. I donno how frequent it is, but i noticed it once.
    also, whenever someone calls me i get the call very late, i.e. just when the caller is about to reach my voicemail or disconnect. I have tested this by dialing my phone from a number of other phone including iPhone 4 & 4S from At&t
    coming to the battery issues, i ALWAYS have my time zone off(i put my clock 10 min ahead), so i dont see the issue others are facing. But once in a a while i can see the battery dropping from 80% to dead within an hour or two without any usage. I got my iPhone 4s on day 1 and this happened about 4-5 times till now. Everytime i saw this happening, i would terminate all the background apps but that dosent stop the battery from draining.
    I went to the apple store yesterday to have it diagnosed and they sent me away telling that I need to make an appointment.
    Is anyone else facing the same issues?
    Please share the solution if anyone was able to get around these issues.

    Hi,
    I had battery issues with my iphone5 ever since I updated to the latest IOS. My battery was draining really fast and my phone was really warm. What I did to solve this problem was: Go into Settings>Mail>Fetch New Data>Push,and make sure you switch push off. In that same section make sure that fetch is set as manually. This means that you have to check your emails when you want to - instead of the notifications going off every minute draining your battery.
    I hope this helps anyone with the same issue.

  • Mac Book Pro Retina 2012 Battery Issue

    guys i wanted to ask about the mac book pro retina 2012 battery issue
    is it best to leave the laptop plug in charging all the time or let the laptop battery to have a full cycle all the time?
    my usage is mainly autocad and photoshop.
    i also have window 7 install on boot camp to play battlefield 3
    my mac book aged 12 weeks adn the battery loadcycles is 78
    Battery Capacity : 8259mAh
    Design Capacity :  8460mAh
    i also read on apple support saying it's advicable not to leave the laptop charge in. i ask on some forum some plug in all the time some perform full cycle.
    so which is the best procedure ( plug in all the time / perform full cycle ) so that the battery can last for 5 years.

    so what you're saying is for heavy usage plug in the charger
    for light usage like web browsing, listneing songs, check mail,etc use battery right?
    You're right
    what's the best ideal to drain the battery ( use the battery until how many percentage ) 5% or 20% then charge it.
    in malaysia the reseller says 5%. but some says 20%
    I recommend to charge it at 20% and use all the battery until your Mac shuts down at least once a month. With this, you'll have a healthy battery

  • Another battery issue thread

    hello heres my **bleep** battery story.
    On 11/13/12  at 7pm I received my cyan lumia 920.The battery came with about 30% battery life and i played around with it for a little bit and put it on the charger. At 7am i removed the phone from the charger and went to work.  between 7am to 12 pm
    -I checked my email  3 times
    -made 3 phone calls ranging  from 3-8 minutes
    -sent 3 texted messages
    -checked twitter for maybe 5 minutes
    -took 1 picture 
    -was on this forum reading some posts for about 10 minutes
    and my battery dropped down to 52% from 100%
    i called Nokia regarding this and i was on the phone with  a rep and that phone call last 6 minutes and my battery  went from 52% to  39%.By 1pm i had about 15% left. i called att about getting a replacentment  and my  battery dropped to  9% after 4 minutes.( if i return my phone to  an att store i cant get a cyan. i have to  mail it in and be without a phone for 2-3 weeks)
    is this normal for thsi phone? did i just buy a phone with a sub par day time camera and a battery that wont last  a few hours?
    I have  
    -2 emails emails set to  sync  every hour
    -battery saver on 
    -wifi off
    -bluetooth off

    -tap to send off
    -location on
    -kids corner off
    -brightness auto
    -find my phone off
    -feedback off
    -high sensitivity off

    Hi Joeynox and Sam87,
    I too had battery issues with my new 920 when I received it, however after about two or three days and a couple of battery charge cycles, it stabilised and "broke itself in". I now get about 12 hours usage and still having 35% left after making 20 or so text messages, 2 two minute phone calls, ten minutes of Angry Birds, 15 minutes of browsing the internet, and listening to music on the phone all day, with the phone not being in flight mode.
    If you are still having problems after a couple more days, i would suggest performing a hard reset, then if that doesn't work, to take your phone back to your point of purchase at AT&T. We have had numerous complaints and they seem to affect AT&T models of the 920, may have something to do with the AT&T applications installed on it causing conflict.
    Also turn off your NFC through tap+send in the Settings, that may help....

  • Advice for ppl that have Battery Issues

    Hi everyone,
    I been using my Lumia 800 since December and recenty updated it to the latest firmware version.
    I charge my Lumia via USB every night and it lasts me for a good 13+ hours with lite/medium usage. Usage such as checking Facebook/Twitter updates, Fuse for RSS feeds, Outlook/personal e-mails, messaging, playing and download music and light gaming about 15 minutes.
    I usually leave my Wifi turned Of. Only in places I turn it on are at Wifi hotspots which I have passwords to.
    After recieving the latest firmware I hard resetted my phone and started from scratch no complaints. If you having battery issues after the firmware update this is what I recommend
    1. Perform a hard reset on your phone
    2. Charge the phone to max using USB. I heard the faster the phone charges the faster the battery will die so I charge my phone nice and slow via USB every night
    3. Run the basic applications and see how long your battery lasts you for. So run your phone with the stock apps for a day and see how good it lasts you and then slowly start adding apps. Maybe theres an app in the background messing up your battery life etc
    Give this a try and see if it improves your day to day experience I can go through a day with ligjht/medium usage but usually I charge it at night. From what I understand this update focuses on Idle time so as long as your phone is in idle it shouldn't eat alot of battery.
    Let me know what you guys think and if this helped you guys with your battery problems. If you guys have any questions you can hit me up on twitter @based_graham

    you could choose to back it up if you want. The important thing is that you do not restore after u formated your iPhone to your backups.
    Go here for learning how to disable iTunes backup:
    http://iphonefreakz.com/2008/07/27/windows-users-disable-itunes-backup-for-faste r-sync/
    for now u can choose to cancel (x) backup. sync your photos and videos and contact info and etc.
    one more point, you must reset to erase all data and content. restore alone will not fully erase your phone.

  • Ipod touch 4g cracked screen w/ warranty . battery issue too

    hey everyone
    i just came back from my long vacation, while on vacation my little 3 year old sister dropped my ipod (long story) but yeah now my ipod touch 4g 8gb is screen is cracked. the ipod still have warranty until january. is it possible to get a replacement/repair from apple?
    also on the very same ipod i have some battery issue, it takes me roughly almost 2 hours to charge my battery full and it drains like crazy! maybe 2 hours of usage and its done.
    thanks!

    An iPod that has been dropped such that it cracked the screen will no longer be under warranty. You can take the iPod to an Apple Store and hope - it's been reported that in some cases the technician has been allowed to replace the iPod under warranty even though Apple is not obligated to do so for user abuse - but you may well have to pay the replacement charge.
    Regards.

  • Q10 battery issue

    2:31 PM
    I bought a Blackberry Q10 on Wednesday. One of the reasons I bought it was for battery life, however I have been having issues with this. The blackberry loses about 10 in an hour without any usage and with email synching turned to manual. I also have task manager and there are no apps running in the background. I go to bed with 50 percent battery and wake up to a dead phone. Is there something I should do or should I send it back? I got the phone just over 2 days ago, and updated it straight away. Wifi is only on during the day. ( I posted this before but accidently clicked on accept as solution even though I didn't mean too)

  • Razr battery issues phone getting hot!

    I did the most recent update for my phone and now I am having battery issues.  I can fully charge my phone and by the end of the day the battery will be dead.  Also I have noticed it is very warm to the touch.  I don't use it much so it is not an issue of usage.  This is the second Razr I have had the first one took a crap and would shut down whenever I powered it on.  At this point I am not really impressed.  Any suggestions would be appreciated.  Thanks.

        I know how important it is to get the most out of your battery life bigback5! The latest update should actually improve your battery life.
    It sounds like you may have apps that are conflicting with the new software. I recommend running the device in safe mode for a full day to test. I have also included some great battery saving tips as well!

  • Battery issue.  Will Apple replace?

    My iPhone 3G is less than a week old and is delivering horrific battery performance. I've read all the reviews as to what is "normal", and have followed Apple's instructions to get more life (3G, push, and wifi off; my screen is at about 10% brightness) to no avail. Below is a link to a screenshot I just took. With the above settings, I was only able to get about 22 hours standby, 2 hours usage, and 22 minutes talk.
    The battery on this is absolute garbage. What is the point of buying the 3G if you can't reasonably use any of the features??
    http://www.me.com/ro/mhommes127/Galleries/100194/photo1216818979929/web.jpg?ver= 12168189790001

    Tough to say -- My battery was good for about 24 hours the first couple of charges but I have read that the battery stretches about 10 or 12 charges into its life. Lately I can get about 48 hours of standby and 3 or 4 hours of usage.
    I would keep an eye on it and after another week or two maybe go in and talk to apple.
    I picked up a griffin powerbolt car charger so I don't see any downtime due to a battery issue for me. Plus, you should consider *everything the iphone does* and charging it every day or every other day - to me - isn't really a big deal.

  • Suprise BATTERY ISSUES!!!!

    I just got the 3g in December. Since then I have heard that battery issues arise so I've been careful to wait until the phone would be completely dead before charging. I had just under a half a battery last night when I went to bed. Woke up to a dead phone. There were not any apps or music running the phone was asleep. I did a complete charge this am and used aim breifly and the phone is already giving me warning messages for a low battery. I'm by sure if this had anything to do but I noticed my usage timer and standby timer have the same reading. Shouldn't they be different times?
    CAN ANYONE HELP PLEASE? I live in PR and there arnt any Apple stores here and the one place I can take my phone to be checked is far. I don't want to be w/o a gone if I have to send it to Apple.
    Thank you

    First, carefully read this about iPhone batteries... http://www.apple.com/batteries/iphone.html
    Waiting to charge until the battery is dead is the opposite of what you should be doing... charge every chance you get. I usually charge every night, even though I only use 20-30% during the day. Continuous deep cycles will shorten the life of the battery.
    Unless your email is urgent, turn off Push and set your Fetch to Manual or the maximum time you can tolerate. Leave WiFi and Bluetooth off unless your using them. Minimize your brightness and close Safari before locking your phone.
    Also, a reset every few days should keep the iPhone running smoothly.

  • Droid RAZR battery issues

    I am having major battery issues now with my Razr. Let me explain some of the things I've observed.
    Number 1. When discharging it might drop to 99-98-97-80-40-39-38-20-4% as I witnessed today, right before my eyes while using it in a matter of a few minutes, and it gets hot too. When charging, it will charge up normally to around 30%, then jumps to 100 and says charged.
    Number 2. This seems to be a much bigger problem when using 4G. I just recently got 4G here, and ever since then, my phone is always a little warm and just eats the battery. I'd noticed this before, when traveling from here when it was still just 3G, to a 4G area. It is such a problem that when I went to Florida this past summer, I had to stop at the verizon store for them to check it out, because it was dying way more rapid than I was used to, always being on 3G at home.
    My phone is so bad now, that I dropped it from 100 to 4% in around an hour yesterday, and about 50+ minutes of that was idle and screen off. Then again later, I was using it to check the weather and it again went from 80+% to 15%, and quickly dropped to 9% in a matter of moments.
    I have changed nothing about it that would cause this level of drain. Location and everything else is off. I checked to see what is using the battery the second time it happened, and is says it is mostly screen and android OS.

    My daughter has had the exact same problem.  It worked fine since end of July when we got it as her regular two year upgrade plan until about a month ago.  She hasn't added any new apps and hasn't changed her phone behavior.  She does all the right things with turning off wifi and I've done the cache partition wipe twice and it sill does it. It gets so hot that the phone actually exhibits a warning message that it needs to shut down.  And it happens almost daily now. I've checked what's been using battery and Google Services seems to be the main culprit--with Google Play services and Location services using almost as much battery as the screen.  I've also uninstalled updates to Google Play services, rebooted and installed updates again and the overheating/battery drain still continues.  I am planning on taking her phone to Verizon and asking for a replacement.
    I've scoured the internet for answers and not sure what to do.  Hoping it's a phone issue. It seems ridiculous to have to turn off all the connectivity and functionality of a smartphone just to be able to have it work properly.
