Battery Percentage Error
My iPhone 4S battery drops suddenly within a sec. It can drop from 40% to 29%, 30% to 14%....I am using the original adaptor to charge my battery. Just an hour ago when I reached home the battery is 30% and I didn't use it afterwards. My phone was in lock screen mode. After around 20 minutes when I press the home key I found that the battery level was 5%. I then plug in the apple adaptor and the battery % went up to 25% immediately but dropped to 7% after few seconds.
I hv no idea on this but just shock. The drainage problem has been occurring for few months after upgrading to IOS 7 few months ago, and the problem is getting even worser in the past two month.
I haven't turned on any location service. I visited Apple Store in Oct 2013 and had a test on my phone battery. It still had a 90% life at that moment.
Anybody knows if it is a problem on IOS 7.0.4?
Maybe you need to re-calibrate your battery.
Charge till full, play a graphics intensive game or something similar till it switches off by itself, then charge till full again.

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.

after upgrading to ios 5.1 on my iphone 3gs, the battery percentage dosent work well, it dosent move. how can i fix the problem?
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.

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!

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! -
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,
GophaAfter 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. -

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:

However, % battery is not accurate on an iPod -

Preface: Please forgive my technological ineptitude in advance. I am completely computer illiterate and have embarrasingly little tech vocabulary.
Okay. Help! While my MacBook Pro is plugged in and charging, the battery percentage is going DOWN instead of up. Yikes. If I stop using the computer, close it and let it charge, the battery percentage goes up when I check it after 20 minutes or so. As soon as I start using it while it's still plugged in however, the battery drains (goes down even though it's plugged in). I've pasted the System Report on Power below (I have no idea what any of it means), the recommendation was from another topic forum. Does anyone know what is happening w/ my laptop? It should also be noted that this is a brand new charger (60W MagSafe Power Adapter), but was still happening before with my old charger before it died (the magnetic piece detached from the part you plug into the computer). Also, it seems to be getting really hot (the new one AND old one!) Thank you for your help!!!

This is normal. When cpu/gpu intensive activities are run, sometimes computer

Why is my battery percentage going up and down while charging? It's not rapid, for example, it was on 78% for 10 minutes, jumped up to 79% for 30 minutes and then it just jumped back down to 78%

First try a Reset ( No Data will be Lost )
Press and hold the Sleep/Wake button and the Home button at the same time for at least Ten seconds... (But can take Longer)... until the Apple logo appears. Release the Buttons
If no joy... Try a Restore...

My ipad 2's battery percentage is stuck at 95%!!! Eventhough I charge 5 hours, it is still 95%...After that, I unplugged the charger, I use my ipad for 3 hours, it is still 95%!!!!! What's wrong is it?! HELP ME
You probably need to recalibrate the battery. See link below.
Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) 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 (2.5W, 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.
