Unusual Battery Behavior

Hi,
I have a white macbook that I recently bought this past June, and I am having some battery problems. My battery has always lasted ~6 hours with a full charge and the brightness on the lowest level, if I have airport on, it drops to ~5 hours. However, I recently did the firmware update, and I have also noticed that my battery levels have significantly dropped. A full charge now nets me a little over two hours? My battery says that I am at 99% but I only have two hours of life left. I don't understand this at all. The only program I have running is Safari, so it's not like I have a movie playing or something like that. I have calibrated before and I can try that again, but, I stll don't think it's going to have an impact. I just don't know why my battery has all of a sudden changed, when my use has stayed the same. Is there some way to see if a certain program is running and draining the battery? Any help here would be wonderful, thanks everyone.

Open Applications in Finder. go To the Utilities folder. Now start *Activity Monitor* and check the CPU window. In the upper right hand part of the window click the drop down and choose *All Processes*. I usually click the *% CPU* header in the bar across the window. This allows me to sort the highest use items first. This should allow you to see if anything is hogging the system.

  • Unusual Battery behavior: Possibly Obsolete??

    I have an old version PalmOne LifeDrive (TM) with a 1660mAh battery.
    1) can I replace the battery with the new standard 1850mAh without damaging my device?
    2)The battery has been charging with power rating jumping to 55% dropping to 7% etc... while charging. Is this a battery issue or is my palm going bad? I read somewhere about soft reset and did that but the problem persisted. Before I did this I have charged the battery for hours but it was dead in the field.
    Post relates to: LifeDrive

    1. You can replace the battery as long as it states it is for the lifedrive. It should not damage the device as long as it is a compatible replacement.
    2. the charging issue could be related to 3 things. The battery, AC charger or the charging circuit in the handheld.
    I would replace each item separately to see if it makes a difference. Start with the AC charger then the battery and last repair the lifedrive.
    It has to be one of the 3 that is causing the issue.

  • GS60 Pro - Erratic battery behavior

    My GS60 Ghost Pro has a strange battery behavior since I got it earlier this week.
    As an example, I did a powercfg -batteryreport and got something like this:
    16:23:34   Active    AC    98 %    53,291 mWh
    16:32:36   Active    Battery    98 %    53,280 mWh
    16:34:44   Active    AC    98 %    53,280 mWh
    17:05:58   Active    Battery    98 %    53,280 mWh
    17:06:04   Active    AC    98 %    53,280 mWh
    17:09:11   Active    Battery    98 %    53,280 mWh
    17:09:17   Active    AC    98 %    53,280 mWh
    17:18:27   Active    Battery    98 %    53,280 mWh
    17:18:33   Active    AC    98 %    53,280 mWh
    As you can see, it switches between AC and Battery by itself while being plugged in. It happens randomly. Other times charge goes to -1 mWh:
    20:52:40   Active    AC    100 %    53,860 mWh
    21:19:44   Active    Battery    -   -1 mWh
    21:19:47   Active    AC    100 %    53,860 mWh
    21:34:49   Active    Battery    -   -1 mWh
    21:34:52   Active    AC    100 %    53,860 mWh
    I have also managed to get a "Battery not detected" message while the laptop was not even plugged. Powercfg reported:
     Installed batteries
    Information about each currently installed battery
    No batteries are currently installed
    Again, the laptop was running from the battery when getting this message.
    I have tried to do an EC reset and to run the MSI battery calibration tool, but this has not fixed the issue.
    Is there anything else I can try? Or is the battery defective and I should contact MSI already?

    No, it`s really simple, hold your finger on an icon for a few seconds before they start to wriggle, and hit Delete, or "X" i`m not sure.

  • Weird Battery Behavior in 7.1.1

    Has anyone else noticed weird behavior after upgrading to 7.1.1 - on my 5s its not that the battery is draining quickly - in fact its showin 5 hours 40 minutes usage with 75% remaining - which i find hard to believe
    whats weird is standby time equals the usage time but i have turnd off and aback on the iPhone - I even did a hard reset - i have a monitor program which is showing the cpu as mostly idling at 90% or more ( although the monitor probably doesnt know about the M7 chip - it probably doesnt even know about the A7 chip too)
    The battery percentage is not going down quickly - it seems to be thr same rate as with 7.1 but i dont believe these numbers
    Im going to let the battery drain completely and do a battery calibration - that some times helps after IOS upgrades
    But i was wondering if anyone else was seeing this and had any suggestions

    The problem has always been an errant app that got stuck in a loop. It can happen any time, but is more likely to happen right after an update. My hypothesis is that the update process suspends running apps, and sometimes after the update they "lose their place" and spin their wheels trying to find it. (It's easier to say it that way then to talk about race conditions.) What will frequently fix it is to run the battery all the way down until the phone shuts off. This terminates all processes, even those that cannot be killed from the Quick Launch screen.
    You can also try to find the app; if it's email turning off any Push email accounts, rebooting, and turning them back on will frequently fix it. If it's a 3rd party app killing all apps in the Quick Launch will frequently fix it.
    Sometimes just turning off the phone for a few minutes will fix it.
    Restoring the phone as new will usually fix it, but restoring from backup may not, because the app state may be preserved in the backup.
    It really just a matter of trying things like these one at a time. One of them will work.
    Do you or Trevor have a CPU monitoring app you believe is a quality application?
    I've tried several, and haven't found any that I like. I like Trevor's answer.

  • Early 2011 MBP 17 Random Shutdown and Battery Behavior

    Hi all, new to the forums here.
    I recently purchased a refurbished early 2011 MBP 17' 2.2 Ghz i7 with 8gb and 10.7.5. Out of the box, machine looked great, but I noticed that the power cable was different than the one I had for my early 2011 MBP 15' I have for work. This raised an immediate redflag (buying from a refurb site outside of apple is always a cause for concern IMO) so I abstained from using that charger until I knew a little more. I plugged in the machine and booted it up and everything worked great. The batter was close to 100%, so after charging for approximately 20 min, I unplugged it, and the laptop immediately died. I powered it back on, and the harddrive began to spin for a few seconds, then the same result, total loss of power. Started up again, and I was able to boot into OS X and play around for a bit for a period of time before again, shut down.
    For the next few days, same story. I was able to at one point, drain the battery completely and do a full cycle charge. The first time I did this, no change in behavior. Again, a few days later, I was able to drain the battery and perform a full cycle charge, but this time, a major change in behvior. Since the second full cycle charge, I have had absolutely no power problems. I haven't really "pushed" my MBP to see if fully utilizing the CPU/RAM/GPU will produce the similar results I had early, but it appears that everything is working great.
    Here a few interesting notes to my situation.
    When I was first operating the system (when plugged in, there were no shutdowns, only while on the battery) I pulled up my system report, and noticed that my battery cycle was very low (~5). This seemed odd, because I had opted for a used battery instead of a new one.
    Prior to reinstalling Mountain Lion, my volume up key would trigger a few strange events. The screen for briefly get quite bright, then all open applications + the doc and widgets would restart (similar to killing explorer.exe in the windows task manager).
    Since performing the fresh install, I have had abslutely no issue with my MBP and I love it, its a beautiful machine. However, as I purchased refurb, I'm hesitant to proceed (I will exceed my return period in ~2 weeks) without knowing my machine is in prime working condition. I have read issues about early 2011 models having issues with batteries and GPUs, but my symptoms were dissimilar to those described by others with those particular issues.
    Any thoughts?
    I have a genius appointment tomorrow evening for a general diagnostics check, but if others have experienced these issues, I would appreciate some input.

  • Need Help with Unusual Table Behavior

    I've been asked to create a table with unusual behaviors, and I'm a little stuck on how to implement it. The table has cells with dates and blanks in it. The following rules need to work:
    1. If the cell has a date in it, then:
    a. If the user single-clicks on the cell, the cell should be selected. At most, the date could be highlighted and copied, but not changed
    b. If the user double-clicks on the cell, a popup window should appear that allows entry of detailed data about the date. This overrides the default behaviors of entering edit mode on double-click.
    c. If the user presses F2, the cell should enter edit mode and allow the user to edit or remove the date. This prevents the user from accidently changing an existing date, which is supposed to be a rare occurance anyway.
    2. If the cell has no date, then:
    a. If the user single-clicks a cell, double-clicks a cell, or uses the keyboard to navigate to a cell and then begins typing, the cell should enter edit mode and allow the user to enter a date. Once a valid date has been entered, the rules for #1 apply.
    Optional:
    The user can remove a date by clearing the date, but it would be nice if they could select multiple dates for deletion.
    Any ideas would be appreciated. Right now, I'm stuck on how to make the cell editable with a single click depending on whether there is a date already in it.

  • Please Help - Highly Unusual AddressBook Behavior

    I'm having a really strange problem with Apple's address book that I was hoping somebody could give me a hand with.
    For some reason, every time I open the address book app, no application window opens, though I do see the 'address book' app menu appear in the finder's menu bar. The only way I can get the address book application to appear is by going to the 'Window' menu and choosing the menu option 'Address Book'.
    Doing so does cause the app's main window to appear, however the problem that occurs at this point is that it doesn't allow me to click anything on the window (meaning I cannot select any of my contacts because clicking doesn't highlight them or do anything).
    In tinkering with it a bit, I've discovered that the only way I can actually select anything (and thereby even use the address book) is do the following:
    -- Choose 'address book' from the 'window' menu, wait for the un-clickable window to appear, then drag the lower right-hand corner of the window to resize the apps main window... Doing so causes the address book window to appear all white (as if it has frozen and is about to force quit itself ~ +though it's not frozen+);
    -- Then I press Cmd+W to close the white window;
    -- Finally, I then if I go to the 'window' menu one more time and choose 'address book', it hides the white address book window from view, and selecting it a second time immediately afterwards, brings the address book window to the front again and I can now click on it and use it normally...
    As I stated in my post I realize that this is a highly unusual phenomenon and I really don't expect anyone here have an answer for what the heck is going on!
    I have done the following troubleshooting steps to try to fix the issue myself, and nothing has worked:
    -- I've trashed the address book preference file
    -- I've temporarily disabled MobileMe & Google Contacts Syncing (which are both normally enabled)
    -- I've used Disk Utility repair permissions
    -- I've used Cocktail to run a battery of maintanence techniques (such as emptying caches, running daily weekly and monthly cron scripts, cycling logs, etc...)
    -- I have of course restarted several times,
    -- And I've tried restoring an old exported 'Address Book Archive' file
    Needless to say, nothing has fixed my problem!!
    I would be beyond grateful if anyone could help me out with this issue, as I've run out of options here...
    Any suggestions would be greatly appreciated... thanks for your help!

    Create a new account, name it "test" and see how your AddressBook works in that User acct? (That will tell if your problem is systemwide or limited to your User acct.) This account is just for test, do nothing further with it.
    Open System Preferences >> Accounts >> "+" make it an admin account.
    If the problem is present in the test account also, then it is systemwide. In this case try repairing this with the 10.5.5 Combo Update This is a fuller install, as opposed to an incremental "delta" update so it should overwrite any files that are damaged or missing. It does not matter if you have applied it before.
    Remember to Verify Disk before update and repair permissions after update from /Applications/Utilities/Disk Utility.
    If the problem does not appear in the test account try starting in "Safe Mode" (It will take a bit more time to startup because it runs a directory check first).
    If that works go to System Preferences >> Accounts >> Login Items and remove them. Boot normally and test. If there are still problems, go to ~(yourHome)/Library/Contextual Menu Items and move whatever is there to the desktop. Then do the same with /Library/Contextual Menu Items. Lastly, try moving /Users/Home)/Library/Fonts to your desktop and restarting.
    Log out/in or restart, if that sorts it start putting items back one at a time until you find the culprit.
    Let us know.

  • Anomalous Battery Behavior/Reporting

    Hi guys,
    I've had my 3G since the summer of 2008 and I will be the first to admit I have not taken the greatest care of the battery in this time span (I tend to charge it overnight, and this often translates to overcharging especially when it's not that low). This isn't a complaint about reduced charge capacity.
    Lately I've started to notice with the recent OS update that my battery has not been reporting its charge status accurately. I enabled battery % in the iPhone options and also pay attention to the "graphic" meter next to the percentage on the desktop.
    Here's a novel example of what is going on: Last night before bed, I checked my phone and it said the battery was at 100% and the battery graphic reflected this. I knew this was wrong because I used the phone quite a bit yesterday but nevertheless I said okay fine, I won't charge it tonight. Fast forward to 20 minutes ago. I check my phone and the battery says it is at 1% in the red, and the graphic reflects that 1% status. Shortly after, the phone shutdown b/c of low batt.
    I plug it in, it turns on and shows the lightning bolt and an empty battery with a tiny bit of red. 30 seconds later, the meter shows 30% full and is now green. 5 minutes after that, the charge meter is still green, but now says 20%.
    What should I make of this behavior?

    Hi iBook fan
    Apple recommend that the battery be 'exercised' once a month, which means fully charging it until the charger turns green, and then using it solely on the battery, until it gets so low that that your laptop goes to sleep. Then once more charge it to full, and that is sufficient to keep the battery calibrated.
    In between, you can run it either on battery or charger, however there is no need to have it on the charger all the time. But, if you are doing power intensive activities like burning disks, or performing a long operation like a backup where you don't want the power to fail, then using the charger is recommended in those circumstances.

  • Unusual Battery discharge while charging ?

    Yesterday , i had the ac adapter plugged in to my notebook (yes it was put in properly)
    but,the battery kept on discharging :/
    i noticed it just when i was going to power it off
    the battery sign up there said discharging , the battery level said (3% left),the battery sign was red
    I checked the socket etc ,everything was fine,
    i waited a minute,battery level was now 1.5 %
    thought i'd deal with it today,
    however ,today the battery seems fine
    its charging alright,(atm 15.7 %)
    any idea what would have caused this ?
    If my reply was helpful please click the "Kudos" star.
    If your problem is solved please click the "Accept as Solution" button

    Thanks for the help!
    But, it seems that the battery will go from down from 100% even when plugged in(right now it says 72%...and will keep going down until I put it to sleep). Also, when the battery is not fully charged from being unplugged for awhile, it won't charge when the computer is on (green on magsafe light). This has only started happening last month or so and seems like very abnormal behavior.
    I've owned the mac for a little over 2 years, and it has always made faint noises, but the buzzing is new--it definitely doesn't sound like a fan. It only happens when the AC is plugged in.

  • Awkward battery behavior. Any ideas?

    Ok, here's the dealio. I have a six month old MBP 15". After analyzing my battery's behavior, I think something is going on. I have smcFan Control and iStat so I'll post what these apps have on it.
    Fan Control: Currently at 73 C & 4604 rpm each fan.
    iStat: 4604 rpm each fan.
    With medium brightness, only medium browsing I get about 1:30 hrs of battery use. It takes around 3 hrs, at the least, for the battery to fully charge. The top-left portion of the MBP, top and bottom, gets medium hot to very hot. I have tried placing the MBP on a level surface to no avail. Any suggestions?

    Hi JaMore,
    The "idle" rpm on that machine is around ~2000 RPM. The fact that you're over double that would most definitely indicate an issue. In Activity Monitor, if you show "My Processes" what else is running?
    Let's try this... shut the machine down for an hour or so (or overnight to ensure it's cool) and then start it up. Let it sit, idle, on the desktop with nothing running. Do the fans immediately ramp up? If not, go to use the machine as you normally would and take notice of what you're running. If so, go ahead and make a new user account on the machine and login to that user. Does the issue persist there as well?
    The fans on Apple portable computers are typically "reactive" rather than "proactive" so the fans may run for a bit even after the load-bearing process quits.

  • Erratic Battery Behavior after 2.0 Update

    Ever since my I updated to the 2.0 firmware my battery life is horrible. I have a nearly full charge and put my ipod to sleep at the end of the day. I get up the next morning and the battery is so drained the ipod won't start up until I plug it into a computer. what gives? Do I have a defective battery? I just got this thing in May. It shouldn't be having a problem like this. I want to take it to a genius bar but I'm afraid they're just going to tell me the battery issue is from wear and tear. I do have apple care on this.
    anyone else having this problem?

    No, it`s really simple, hold your finger on an icon for a few seconds before they start to wriggle, and hit Delete, or "X" i`m not sure.

  • Sudden shutdown- then strange battery behavior?

    About a week ago I was using my 2009 Macbook before I went to take an exam. When I left it had very little battery left (it has given me a warning) but I just shut the top and left, figuring it would go into Safe-Sleep. When I came back, I found that the fan was running very loudly and that the screen was dark. When I plugged in my MagSafe charger, it didn't recognize that it had been plugged in. In an attempt to prevent the fan from burning out, I took the battery out for awhile and then put it back in again... and the fan began to run again. I figured I would let it run for a little while and eventually the fan turned off and a while after that the computer turned on.
    Ever since, I've been getting strange readings about my battery from the built-in indicator and my iStat Pro widget. When it's not plugged in, the built-in reader doesn't tell me how much battery is left, but instead lags and then tells me that it is plugged in and "Not Charging"
    Right now iStat Pro is telling me that my battery is 29% charged when not plugged in but when I plug it in it tells me that I have 10 hours of charging remaining until I reach 100%.
    I'll have this laptop for a year next week, it seems a little early for battery problems of this scale. I swear I haven't dropped it! Anyone have any ideas before I bring it in?

    My iBook seems to take a long time (15 minutes) to calculate the battery charge.

    Run it until it goes totally dead in which case the machine turns off. This does not mean to go into sleep or hibernate. Thats not dead!!
    You either have to configure power manger to not do anything in case of weak battery or boot into something else where there is no power management EG CD tool or something.
    The fully charge it and see what its says for its level. Once charged you can go into the TVT Powermanager and look at the state of the battery and also confirm/test it further.

  • Weird battery behavior

    A week ago while running on battery power my machine shutdown with no warning. I couldn't get it to power up until I plugged in the charger. My battery indicator at that time said "0" but I had been running on somewhere north of 70% when the shutdown occured. It obtained a full charge, according to the indicator, in about 20 minutes, which is unheard of for me when starting from zero.
    Today, again while running on the battery, my machine hung for just a couple of seconds when I opened it and was about to resume work. (I hadn't logged out or put it to sleep prior, but simply closed the display, which is what I generally do when security isn't an issue.) I noticed almost immediately that my battery indicator read "0" where I would have expected it to be close to fully charged. Nevertheless, the machine didn't power down, and I used it for several minutes before rebooting to see it rebooting would reset the power indicator. It didn't. I used it for a few more minutes, then did a full shutdown. When I returned to the machine an hour later, it wouldn't power up until I switched to a different battery.
    I have practically no experience with laptops and battery issues. This particular battery is less than a year old. This all reminds me of mobile phones I've had in the past that would suddenly power down or refuse to power up because the battery had become loose from use. A temporary fix for that was a business card wedged between the phone and the battery, but I don't think that's a great idea with laptop.
    Anyway, just wondering if anyone has had a similar experience?
    I'll keep you posted as the situation plays out.

    There are known issues with the MBP batteries, which resulted in Apple extending warranty coverage for batteries to two years for all Core Duo laptops (they did not extend C2Ds, but those are all still under warranty). That extension is described on the linked page below, along with the statement "Apple has recently discovered that some batteries used in its MacBook and MacBook Pro notebooks may have battery performance issues."
    http://www.apple.com/support/macbook_macbookpro/batteryupdate/
    Check your cycle count in Utilities > System Profiler > click on Power. If the Full Charge Capacity is less than 4400 mAh for a 15" MBP or less than 5000 mAh for a 17" MBP, the battery is failing. Also check the cycle count. If you have more than 300 cycles on your battery, Apple will tell you that your battery is failing normally, and you will need to buy a new one. If you have less than 300 cycles on the battery, based on the symptoms you describe they will replace if for free (as they did for my 15 month-old out-of-warranty MBP).
    Hope this helps...

    I know my cycle count is high, which has something to do with it, but lately my full charge capacity has been dropping dramatically. I did a textbook Apple battery recalibration last night following all instructions, and my full charge capacity DROPPED from 1840 to the above stated 1584. Is this normal? My cycle count is high, but it isn't as high as what would be reflected in my charge capacity, correct? Can anyone help me out or have any ideas? Is it just time to bite the bullet and buy a new battery?

    That's possible, I suppose but more likely:
    Overcharing lithium batteries is really bad. So bad that well designed devices turn off charging when the capacity is reached. At this point, I believe one of two things can happen. The device might be powered by the charger, however with the battery no longer receiving any charge, or (easier) the device can run on the battery after the charger has been disabled. The plug icon in the battery icon indicates charger not charging but connected. I think the iPhone is smart enough to run off the charger while not charging, however batteries can lose charge over time even when they are not being used.
    The computer takes longer to charge the battery so it spends less time connected but not being charged than when you use the wall plug. I've seen this on a Palm PDA as well, although a little more dramatic. I believe the Palm was not smart enough to run off the charger and instead ran of the battery. Depending on when you disconnected, it could be truly fully charged or a few % low.
