Battery percentages incorrect?

Has anyone else noticed that when fully charged the iPhone takes a while to go from 100% to 99% and from 99% to 98%, like it has a lot of battery and it's not draining fast? But then it can drain from 30% to 20% or 20% to 10% much faster? Is that some kind of software bug or what?

Maybe the battery sensor needs calibrating.  Leave the phone on, running an app that draws power (such as a flashlight or movie) until it shuts off, then charge it to 100%.  You should do this every month or so.

  • Incorrect battery percentage on my iPhone 4

    I have an iPhone 4 and in the past few days it has been showing the incorrect battery percentage. The other day I charged my phone all night and woke up with only %7 battery so I turned it off, but when I turned it back on I had %100. It also keeps dying when I get to only %60.

  • Bluetooth toolbar icon displays incorrect battery percentage

    For the past week or so, my macbook pro bluetooth toolbar icon has been displaying very incorrect battery percentages for my bluetooth keyboard and magic mouse.
    Using the 'ioreg' tool from teh command line, I can get correct information (both my keyboard and mouse are around 45% battery).
    See below image for the incorrect battery percentage.
    Anybody have any suggestions on how to correct this problem?
    Thanks,
    Matt

    This is a new issue with 10.6.7.  Eventually the battery percent will start to decrease.  Not much can be done until Apple provides a fix.
    There is a widget you can use in dashboard in the meantime.

  • I've seen on apple's pictures of the ipod 5th generation that it has a battery percentage. Yet i can't find out how to turn it on? does anyone know how to?

    When looking on the apple website and iTunes you can see that the picture of the ipod touch 5th gen has a battery percentage indicator but i can't seem to fing the option to turn it on?! Is there actually an option or has apple just added a feature in the photo in which the ipod dosen't contain?

    The 5G does not come with a % battery in upper right. The phtos were incorrect. You may be able to add it by:

  • Battery shows incorrect time and no notification on low battery

    Hi everyone,
    I have just purchased a new battery, of course its not an original one. The problem is that my battery meter shows the percentage incorrectly. Like it says 42% remaining, but suddenly my laptop got in to hibernation (as i set the action to perform upon low battery level reaches). Now what can be the issue? As the battery new and its working fine, i mean its giving me backup of 2+ hours. Oh, and my laptop is DV6-2157wm with Windows 7 Home Editions (64-bit).
    Waiting for your kind suggestions and tips.
    Take care,
    Regards

    Why does the time remaining on the battery meter change drastically sometimes?
    Battery life depends primarily on two things: what you do on the mobile PC while it's running on battery power, and the power plan settings that control the computer's use of power. The mobile PC's power consumption varies constantly, depending on your particular activity and how long you spend on that activity. For instance, watching a DVD consumes considerably more battery power than reading and writing e-mail. For these reasons, the battery meter often lags in reporting the charge and the estimated time remaining.
    hence battery meter is never so accurate. older the battery, chances are more of sudden drop.

    Hello Neygotsole,
    Having your device malfunction can certainly be frustrating. After reviewing your post, it sounds as though your device is experiencing multiple issues. I have located an article that can help with software issues. Have you attempted to restore the device to factory settings without restoring from a backup? Test the issue on a new installation, and make sure that it works. Then use the same article to restore from your backup to either verify it still works, or isolate the issue to the backup itself.

    Have you tried doing turning the battery level display off and then General -> "Reset all settings"? You won't loose any data and that should do the trick.

  • How do I automatically log the battery percentage and time on my Retina Macbook Pro to an excel spreadsheet? (OSX 10.9.4)

    Hello! So I own a 13" rMBP, and I'm running OSX 10.9.4.
    How do I log my battery percentage with the date, probably down to the hour, preferably to an Excel file?
    I want to track the rate at which my battery discharges, so that in the future I can compare the present rate of discharge with the past and see exactly how much my battery has deteriorated by. I'll take averages over long periods of time to account for, e.g. the fact that watching Netflix drains my battery faster than editing an essay. I also want a solution that uses negligible power in the background.
    I've spent hours looking for an app that both calculates the rate of discharge and keeps all data, but I haven't found any. Eventually I decided that hopefully it isn't too difficult to write an AppleScript or something that simply logs the system clock and battery percentage in tandem every hour or so.
    Thank you for your time!

    What Barney said.
    Here is the script to create a CSV text file with
    Date
    Time
    Current Battery Percentage as an integer
    #!/bin/bash
    batterycsv="$HOME/battery.csv"
    export GREP_OPTIONS="--color=never"
    # if you want the percentage sign too, exclude the second egrep
    battpct=$(pmset -g ps | egrep -o "(\d+)%" | egrep -o "\d+")
    datetime=$(date "+%Y-%m-%d %H:%M")
    printf "%s,%s,%s\n" $datetime $battpct >> $batterycsv
    Output on a fully charged MacBook Air to battery.csv will be individual lines of the following format:

    Can I enable Battery percentage on my iPod touch 4th generation running iOS 5.1.1 without beig jailbroken?

    You can enable battery % on ipod touch 4g without jailbreaking it you can use backup bot for itunes. Thats how i enabled it on mine. Step 1: goto http://www.icopybot.com/ibackupbot_setup.exe download and install it if you have windows. Step 2: Next create a backup of your device in iTunes and then CLOSE iTunes (or else you may run into problems later on) do not lock the backup with a password. Step 3: Open iBackupBot. Click the backup you just made Next click "Path" to sort by Path. Step 4: Look for Library/Preferences/com.apple.springboard.plist and double click it. On the registration screen that comes up, hit cancel. Step 5: Find <dict> and create a new line after it. Then add this: 
    <key>SBShowBatteryLevel</key>
    <true/>
    Step 6: Hit CTRL + S or just the save button at the top left corner of that editor window. Now close the window.
    Step 7: Right click that same backup you just edited
    Step 8: click restore
    Step 9: Done! If you don't see the changes, reboot your iPod.
    Enjoy I hope you found this useful!

  • Battery percentage indicator takes a little while to update when resuming from sleep - is this normal?

    Hi folks,
    I recently bought a new MacBook Pro with Retina (13") and have noticed a pecularity with the battery indicator that I'd appreciate an opinion on please.
    I've charged my MBPr battery to full (100% on the menu bar and green light on the MagSafe connector). I disconnect the power and close the lid which puts that MacBook to sleep. After leaving it overnight, I open the lid and and the unlock screen shows the percentage battery having gone down by a couple of percent (which I take to be normal) - e.g. 98%. However, when I unlock and get back to the desktop, it's still showing as 100%. Clicking on the battery icon, it shows as calculating the amount of time left. After about a minute or so, it tells me how much estimated time I've got left, and the percentage indicator updates to give me the correct percentage. When using it normally, the percentage indicator drops on the desktop as I would expect it to.
    Is this normal for it to give the correct percentage on the unlock screen, but then to give the original (pre-sleep) percentage when unlocked, until it has updated and worked out how much time it's got left on battery?
    I've read elsewhere that many folks have been having issues with the battery indicator since Mavericks rolled out, and there are some resets that can be done by pressing various key combinations whilst powering on. I've had the MacBook only a few days, and haven't installed anything on it - it hasn't even been connected to the internet yet - so I assumed that it should be working correctly from the off - unless there's something buggy with Mavericks causing this?
    I would normally shut down a computer overnight, but I like how the MBP instantly resumes when I open the lid. Am also wondering whether it'll take a few charge cycles before the battery reaches full capacity and is properly calibrated. The system report shows that it shipped to me having undergone only 3 charge cycles to date.
    Any opinions would be much appreciated.
    Cheers,
    Gopha

    After some more testing:
    Disabling the battery percentage indicator and then re-enabling it causes the percentage value to update to the 'correct' value. Rebooting the MacBook also causes it to update to the correct value.
    Seems like I'm not the only one with this particular issue: https://discussions.apple.com/message/24402123#24402123
    https://discussions.apple.com/message/24406197#24406197
    as a newbie to Macs and Mavericks, am I right in saying that there is currently an issue with Mavericks?

  • Why is the battery percentage on my iPhone 4S on iOS7 freezing then dropping in big 10/20% chunks?

    Since upgrading to iOS7 my 4s has been having issues with battery meter. Take today for instance, it fell steadily to 59% then dropped instantly to 39% (I was not using any apps at the time). It has now been stuck on 32% for over half an hour, I've taken photos, used YouTube and other apps in an attempt to drain it but no change.
    I've turned off all unnecessary processes, including location services and background refresh to eliminate drain. System status meter shows processor operating at 10% when no apps open so it doesn't look like background processes are draining.
    I can't rely on the battery meter when it isn't accurate, it could suddenly drop to 5% or similar without warning.
    Is anyone else having these problems?  Any ideas Apple?
    It's going to render my phone untrustworthy and inaccurate.

    Hi!
    I am having similar issue.
    I have upgraded my iPhone 4s to the new iOS 7 and since then my battery indicator is stucked at 44%. Now regardless how much I charge or how much I use, it is showing the same battery level.
    Although this get refreshed when I restart the iPhone and it shows the current battery level and then again stucks at the same percentage. This was working fine on iOS 6.1.3, but is showing issues after the upgrade.
    I have tried to restore it, reset settings by selecting Erase All Content and Settings, hard reset (power+home button for 10 sec) but still no good, it shows the same level of battery percentage at which it is since last reboot.
    Although I was having iOS 6.1.3 ispw so I downgraded it again as Apple was signing iOS 6.1.3 at that time. Now the battery percentage is working fine. Therefore its not a hardware issue for sure and is just some bug with iOS 7.
    Now I have again upgraded to iOS 7.0.3, and I am facing the same issue again. And now I can't even downgrade to iOS 6.1.3.
    If you get some tips on how to solve this, then please share the same.
