Fix battery discharge problem?

I have been working with this for 2 weeks w/o success.
Lawrence Finch and others have helped.
First, I tried the battery recalibration and it seemed to work.
I could pass the " battery drain test".
That didn't last.
Now, when I redid the drain test, neither the usage time nor
standby time changed in 5 minutes - that's weird.
Next, I'll try Scotty's suggestions about Background ap refresh.
Following a suggestion, I upgraded this week to iOS 8.1
Alas, that failed, too.
After upgrading to 8.1, the problem remains.
After recharging my phone, I use for one or two calls, one or two messages.
Otherwise, it has been sitting.
During the first upgrade to 8.0.2 some weeks ago,
I added a pass code and downloaded NUMBERS, an app I use heavily on my Mac.
Could either of those be the problem?
I've searched the on-line manual for how to delete NUMBERS to no avail.
I just redid the"battery drain test" suggested weeks ago: noted standby and usage times, pushed the standby
button to put it to sleep, came back 7 mintues later. Result: no change in either standby or usage times.
Previously, I did get a result indicating a battery drain problem.
The battery is dead in 24 hours.
Should I give up and head for the Apple Store?
I'm really getting frustrated.
Thanks so much for your patience,
Thanks in advance for your help.
Many thanks for your previous responses and suggestions!!

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new).  Try each of these in order until the issue is resolved.

  • Is the 10.7.2 fixed battery drain problem ?

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

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

  • IPhone battery discharges even when turned off since iOS 5.1.1

    Since updating to iOS 5.1.1 I have had battery problems, discharging at around 4% per hour even when not used. Turning off every concieveable service and reloaded iOS as a new device unfortunately has not solved the problem. I have resorted to leaving the phone plugged in all of the time and recently started to turn it off overnight. To my surprise, the phone continues to discharge when turned off! I couldn't find this problem when I searched (apologies if I didn't search hard enougth!)

    I have been waiting for months for the next iOS to see if it would rectify my battery drain problem but I continued to have the battery discharge problem after installing iOS6 .
    My Home button has been playing up with random no responses and random double clicks, so I replaced the home button hoping that may also address the battery drain issue - no joy.
    Then I had a look to see if I had added any Apps when the problem first appeared at the time of upgrading to iOS5.1.1. (You can view Apps by date in iTunes on the iPhone Apps tab.)
    It turns out that on about the same day as the iOS 5.1.1 update I also added the Lifesize ClearSea video conferencing App. Today I disabled the App in iTunes (unchecked it) and resynced the iPhone. I believe this removes the App from the phone whilst leaving it in my iTunes so I can add it back easily. For the first time in months my phone is now cold rather than luke warm.
    Superficially at least it seems that ClearSea has been running in the background, even when manually quitted and even when the iPhone was powered OFF! I will report back in a few days to confirm this was the culprit.
    Five months with a phone that barely lasts a day has been a real pain...

  • Does 4.2 fix 4.1s battery drain problem?

    or make it worse?

    Neither. 4.1 does not have a battery drain problem, your iPhone has a battery drain problem. You need to fix the problem at its root. Every version has caused problems for some people, and it isn't a problem in the release, it is a problem with something getting corrupted during the update process. Here's the evidence:

    How to fix iPhone 5's crapy battery drain problem

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

  • When will you fix battery issues on ios 5.1.1? I have the same settings but 85% less battery life!!!

    I have read many tips about what to do for increasing battery life. However
    I hav the same setting with ios 5.1.1 that I was using with the previous
    version (ios 5.1) but with 85% less battery life time. It is so frustrating because this
    issue come back every 2 update : one killing your battery and the second
    to fix this, and it starts again... I am really sick of this.
    I am using an iPhone 4.

    Hi All – I have also experienced the battery drain issue on upgrade to 5.1.1.
    Like many on the forum I have tried ALL suggestions to resolve this issue, none of them have resolved the problem that Apple owners seem to be experiencing, it’s not in our minds as some suggest. My iPhone 4 and iPhone 3GS are working a treat under 5.1.1, in fact I believe the 3GS is running better than under 4.3.x.
    However I do think I have tracked the problem down, which I will document here, but first a list of the things I’ve tried:
    - Fully discharge battery to <5% and then back to 100% and leave charging for 3 hours after
    - Turn off all notifications
    - Turn off all location services
    - Turn down brightness
    - Turn off ALL iCloud services (effectively delete the account)
    - Reconfigure email account to ‘MANUAL Fetch’ only
    - Factory restore to fresh 5.1.1 from within iTunes and then restore from back-up
    The only thing that stops the battery discharging at around 5% every 8 hours is turning off Wi-Fi during standby mode. Prior to 5.1.1 the iPad would drain maybe 1% every 24 hours in standby mode with Wi-Fi on.
    Puzzled by this I did some research to understand what the iPad is doing whilst in standby mode with Wi-Fi on, so below is a trace from the iPad system log so that hopefully someone can look at this , identify the issue and hopefully fix it in a future ios 5.1.x release:

    These repeating messages appear approx every 30 seconds the wakeup packet contains the MAC addresses for my router and iPad, so one of them is misbehaving. This may be to do with how these have been implemented:
    http://en.wikipedia.org/wiki/Wake-on-LAN
    http://en.wikipedia.org/wiki/Sleep_Proxy_Service
    Either way I believe this is the source of the power drain issue whilst in standby with Wi-Fi turned on, perhaps this could be a router issue and that is why the issue not hitting everyone post 5.1.1?
    All the best.

  • 2nd dead iPod Touch 4G in 2 months?  Battery/charging problems!

    Hi everyone,
    It seems as of tonight that I will have to return my second iPod Touch 4G in the last two months. In both cases, it was an issue where the device would no longer charge, and became very hot on the top of the back panel when the device was turned on even for a few seconds (while not being plugged in). In the first case, the device seemed to be defective from the time I opened the box, which was confirmed at an Apple Store, but they asked me to ship it to Apple Repair to be checked out. Apple took a very long time to get a replacement to me, but was good about that problem, and I was happy with the replacement for the past month when all of a sudden tonight the new one would not change and became very hot.
    Is this an issue that anyone else has seen? I essentially only charged it off of my laptop or a wall charger unit, but it seems like the battery essentially is shorting out. I love this device, but actually need to use a PDA-type device enough that I am questioning whether I should get a replacement or go back to my old Palm TX.
    Thanks for any thoughts/feedback on my iPod Touch 4G battery/charging problems.
    Message was edited by: eliotjasper

    Most battery complaints complain about loss of charge. The iPod is designed to lose heat through the back as the battery discharges. This is most common when using the device a lot - like playing games. If yours will no loner charge, by all means return it to Apple.
    As far as being a PDA goes, it is as good as any smart phone out there. The PDA, as you once knew it, is dead and has been for 5+ years. Take your iPod to an Apple store and insist on a replacement.

  • Battery discharging faster since ipad 3 upgrade why ?

    since upgrading my ipad3 the battery discharges more quickly anyone else got this problem?

    What did you upgrade? Should be the same. Have you checked your brightness setting?
    The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
    Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
    How to Calibrate Your Mac, iPhone, or iPad Battery
    http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
    At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

  • Equium M40X -Battery discharging. Please help!

    I recently bought an Equium M40X - 149, and i couldnt understand why when the ac adapter is plugged in the battery discharges itself and the computer switches off! So i took it back to the shop and they said it is just the cycle of the battery and i would need to go into the bios to change the settings.
    I went into the bios but i couldnt find anything that i could change to stop this!! Can anyone point me in the right direction as it is inconvinient for me to keep taking the battery out when i want to use the laptop!!
    thank you

    Hello Gemma
    I dont know if I have understood you right but if the notebook is connected to AC power supply it can not be possible that the unit switches off itself. Not because of power supply. If the unit is connected to AC power supply you can remove the battery and it should work without any problem.
    Sorry but I have no explanation for this and in my opinion you should contact Authorized Toshiba service partner in your country. Explain them the problem and thay can check the unit. The warranty is valid and if there is some hardware malfunction the costs will be covered.
    Bye

    Depends on which issue you have. Apple is working on an update to address a calendar syncing problem with Exchange accounts. Do you have an Exchange account?

  • Normal Battery Discharge?

    I have and continue to have battery discharge issues with my Powerbook G4. I get conflicting answers from the Genius Bar as to whether what I am experiencing is normal or not normal.
    After a 24 hour period of my laptop being shutdown and unplugged from AC power, my battery has a 15min/7% loss. In other words, when I replug in my computer to AC power and turn it on, my computer says that my previously fully charged battery is only 93% charged and needs 15 minutes of charge time. (plus, it takes longer than that 15 minutes to actually reach the 100% charged listing).
    I just replaced my battery and the PMU has been reset.
    Anyone have any ideas? This is an intermittent problem as sometimes the battery remains charged at 100% after sitting for 24 hours and other times it does not.
    Thanks!

    Loosing 7% charge in 24 hours is not normal if the PowerBook was shut down (but would be fine if it was sleeping).
    Are you sure that the battery was at 100% charge when you turned off and disconnected the PowerBook? When using the PowerBook plugged in, the power manager allows for the charge to drop to 95% before charging again.
    The top few percents of charge may be special and hard to measure accurately. I suggest that you repeat your test, but start from a medium charge like 60%. Does it loose 7% in this case, too?

  • I HAVE FIXED THE FAN PROBLEM

    Hello from Turkey. I have just bought a 3000 n200. It's a great machine.
    As you all know, the fan gets higher and gets slower, gets higher and slower again and again.
    IF YOU SET YOUR BATTERY OPTIONS TO  ''BATTERY SAVING'' MODE
    The fan will get REST . I mean the fan will work in normal speed.
     Plus you will get much more battery life
    Try this until Lenovo engineers fixes this small problem (probably by an bios-update) 

    Hello again,
    Whenever i click on something (for example to windows media player, explorer new window etc.), the fan speeds up for 1 seconds and gets low again.
    In this review, it's is clearly told that the fan gets up and down very often.
    ''The fan on this laptop, while having the ability to spin slowly, likes to quickly ramp up at the slightest temperature increase. It also has no delay, causing the fan to quickly speed up, slow down, speed up, slow down, etc. This started to drive me up the wall when some programs were running. I am hoping a BIOS fix comes around to mellow out the fan''
    That is exactly what I am complain about.

  • OS Update & Battery Life Problem

    I thought I would throw in my two cents worth of iPhone 4 OS update. I'm experiencing many of the same problems that other folks have reported on the discussions boards...battery draining, apps closing while using them, etc. My phone is basically rendered useless at this point. I went to the apple store and their solution was to sell me a new battery for $79.00.  I said no-way, there was nothing wrong with my phone prior to the OS update and immediately after the update is when I stared having problems, so no, it's not the battery. The apple store clerk changed the settings on my phone, changed auto-lock from 4 minutes to 1 minutes, changed all my mail accounts from push to fetch, changed locations settings and any other settings that might have an impact on battery life. It helped a little bit, but did not put the phone back to the way it was prior to the OS install.
    I find it hard to believe that apple put out a product without first throughly testing it to make sure it would work on the million cellphones already out there.
    I really hope apple is listening and reading the message boards because they need to come out with a fix for this problem before people dump their iPhones in search of a phone that actually works. Can you say Blackberry?
    Thanks for listening to me vent.
    Kathy

    I am having the exact same problem! Mine was at 80% last night before I went to sleep and was dead again for the second night in a row. I am thinking about resorting. These last few updates released have been the worst ever! I almost missed an appointment yesterday morning but luckily today is Sunday and it was dead again. Have you had any luck yet?
