100% to 65% Battery Level Decrease in Two Hours

My question is: "Is anyone else seeing rapid battery level drop with iPhone since upgrading to IOS 8?"
Since upgrading to IOS 8 on Wednesday the 17th, I have experienced RAPID battery level drop between charges. I am now having to charge my iPhone 5s 32 GB half way through the morning, after lunch and when I get home. If it weren't for my Mophie Jet Pack, a car charger and a charger at my desk, I wouldn't make it through the day. Believe me, I have read every battery conservation tip out there. I have turned so many features/functions off that I'm really starting to wonder if IOS 8 is worth it for the iPhone 5S and below. If I weren't faced with a daunting downgrade process, I would do it. At least I used to be able to make it to 7 PM on IOS 7 before I put the phone on a charger or flipped on the Jet Pack.
Using the new Battery Usage report under Settings > General > Usage > Battery Usage I see that Calendar and Notes apps have taken the lion share of the battery charge over the past 24 hours, and there is a notation stating that the usage was "Low Signal" which I assume means that the phone was trying to do its thing with a poor cell phone signal. At work, however, I am completely on wi-fi and not cell. So this isn't very helpful.
On the other hand, I have an iPad Mini with Retina and an iPad 3rd Gen that have been upgraded. Neither of them have had any problems. In fact the iPad 3rd Gen still has 92% charge after sitting in my backpack all weekend long (since being charged Friday morning). So what I am seeing only seems to affect my iPhone.
I do remember similar issues with the IOS 7 initial upgrade, which were resolved with subsequent patches/upgrades.

Thanks Lawrence. We use CommonTime mSuite to integrate our Lotus Notes with iPhone's Calendar, Contacts and email using the Exchange iPhone connector, and I am one of the administrators for mSuite. I have deleted and re-added the Exchange account on my 5s running IOS 8 multiple times, and have done the same on an iPad Gen 3 and an iPad Mini. All with the same results. (The results are that email comes down, but calendar and contacts do not, and email will reload every so often.) I've deleted the account on the mNotes server a couple of times as well, to no avail. I have an old iPhone 4 still running IOS 7.1.2, and setting the exchange account up on it, immediately everything came down successfully from Lotus Notes onto the old iPhone. This is definitely an IOS 8/CommonTime issue, and CommonTime has acknowledged that there is a problem, though they have as yet no fix. The one good thing to come of this is I now know what was killing my battery. After 7 hours of use last night (regular use on Facebook and Feedly) my battery had only gone down to 83%. Other of our 46 users who have upgraded to IOS 8 have the same problem as I.

The battery level decrease

hi i m sashil recently i update the software of my x3 frm the near nokia care.Nowadays when i chat with my frens using nimbuzz n the listen 3 to 4 songs my battery level decrease.how is that should i have to change my battery

To all who has low battery problem.
please see that all apps are close and exit after use.
use always GSM mode as long as possible.
switch into 3G or 3.5G when ever necessary only.
even after wards battery goes down please see whether u r instrument get heated up.
then it may be due to some app running without u r knowledge. if u cannot trace it, switch off the phone and then remove the battery for a while and then refix.
then heating will not be there and battery can go for some time.
if all fails, try to replace the battery with a genuine Nokia one.
Also please note that I'am giving all these advise practically using and facing problems and getting rectifying the problem myself to certain extent {Presently using Nokia X6 (16GB)}

Year Old MBP - Battery only Good for Two Hours

When I fully charge the battery over night and switch the battery indicator to time the most I get is two hours. Percentage view quickly shows from 100% for a few mins to 75% a few mins later and the most I can get out of it is roughly two hours. Based on these readings do you think the battery is defective?

Well, your battery's original capacity was about 4600mAh, and it still has 96% of that: very good for a year old. So it's there, but something is consuming it. Open Activity Monitor and use it to determine what's using the most CPU cycles. If you're using your machine in a brightly lit setting, make sure your display and keyboard brightness aren't being cranked up automatically: the display in particular is a huge energy consumer. If the Web sites you frequent are video sites like YouTube and Hulu that use a lot of Flash, that will eat up your battery very quickly.

Battery on 24% for two hours with heavy usage.

This has never happened before. My battery was draining quicker than normal today and as soon as it hit 24% it stopped going down. It's been on 24% for about two hours now with heavy usage on 3g (lots of internet, lots of texting).
Any ideas what's going on?

Sounds like *+yet another+* calibration issue. I had one too today, battery was on 77% - then after half an hour of sitting idle it was on 62%! I watched half an episode of +The West Wing+ and it stayed at 62% which is unheard of, video usually drains the battery quite badly - I have since had to plug it in to sync and within about 10 minutes its on 79%.
It's probably not a faulty battery, it's just that the status display meter is giving the wrong reading. I expect you'll get the same number of hours from the battery as usual, and the next time you completely empty and recharge the battery it will recalibrate itself.

My ipod touch has a short amount of battery life of around two hours, but i installed an app that tells you how much battery life left, it said 4 hours, how come? is my ipod touch battery faulty?

my ipod touch 8gb, ios 4.3.2 has a short amount of battery life of around 2 hours, but i installed an app that tells you the battery life remaining, it said 4 hours, how come? is my ipod touch battery faulty

Some useful info would be:
What generation is it?
How old is it?
If it's older than the 3rd generation, then the battery may have run its course (or iOS 4.3 is taking a toll on the battery).
If not, then you might have some issues leaving the wi-fi on and fetching data as well as running apps in the background that abuse location services and notification. Make sure those are off, or only running when necessary. If you see a small arrow in the top right corner (that isn't the music "Play" arrow), then you are currently running a location based service that can drain battery.
Also check your brightness settings, these can really pull battery life.

Battery level decreases when charging ?

I plugged my macbook pro in to charge. It charged all the way up till ~90 something percent. In terms of duration, it said that it would finish charging in two minutes. Then 4 minutes.... 6 minutes. Then I decided to turn it off.
Now that I have turned it back on it is only at 88%.
Weird. Everything seems to work ok.

Keyboard & Battery levels query (2 week old 27" iMac)

Hi,
Keyboard battery level stuck at 100% then suddenly dropped to 67%. Turned keyboard off then on and since then the level has been stuck on 100%.
Mouse battery level indication OK as it ticks down nicely. I've been using rechargeable batteries and they are lasting better than the Apple supplied Energiser batteries despite being old and useless when used in torches / GPS etc.
This issue is not important as I have a plentiful supply of batteries - Just interested. Thanks.

HI,
Rechargeable batteries are definitely the way to go!
Try resetting the PRAM to see if makes a difference in the battery levels.

The battery of my MBA 13 "mid 2011 is lasting less than two hours after installing the Mountain Lion. Would be the OS or apps consumed much?

My MBA is consuming the battery in less than two hours after I installed Lion Mountain. The update has already been done for some time. The problem of consumption would be the same OS, according to several complaints, or were inadequately apps consuming battery?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Battery level for mouse and keyboard always 100%

The battery level shown in the bluetooth menu and in the system preferences mouse and keyboard panes constantly shows 100% and never declines. Does anyone know the solution to this to start getting realistic readings again? I've tried trashing the bluetooth plist and restarting but that hasn't made any difference.
Many thanks for any help
James

One suggestion I have is to do a "full factory reset" of your bluetooth stuff. I'm not precisely sure all that entails but here's how you do it.
1. If you don't have the XCode developer tools installed then install them.
2. Launch the Bluetooth Explorer. It can be found in /Developer/Applications/Utilities/Bluetooth/.
3. In Bluetooth Explorer's Utilities menu select Modify Software & Device Configuration. A window will be displayed with a number of checkboxes.
4. Check the first four checkboxes (Recant..., *Full Factory Reset*..., Delete link keys..., Delete global bluetooth preference...). They may already be checked for you as the default.
5, Click the Perform actions button.
6. Click Reboot NOW button.
After rebooting re-pair your bluetooth devices. Hopefully your power percentages will be fixed too. If not, I have no other suggestions.

Hi,
How old is your MBP? how many cycle batter do have ?
I will also recomend to use the software http://www.macupdate.com/app/mac/24141/battery-health-monitor
to monitor battery life.
You should be able to read everything from the software.
Please post results.

Apple Wireless Keyboard (2011) Battery Level Stuck At 100%?

I got a new iMac, the one that was released by apple in late November, and I went to system preferences > keyboard, noticing that the keyboard battery level is stuck at 100% every time I check now and then... Anyone else having this issue? Fixes? Help?

Hello:
I suggest you install a widget (mighty monitor) that gives more accurate readings.

MacBook Pro battery level indicator is stuck at 100%

Got this MacBook Pro in January of 2008. Great machine, replaced battery last spring and more recently had some sort of repair done when the screen would not activate. No problems otherwise. Now all of a sudden my battery level indicator is stuck at 100% regardless of actual battery charge level. The computer will allert me that it needs plugged in immediately or it will go to sleep, but it would be nice to have the indicator working again. Any ideas?

If it's a pre-unibody MBP with a removable battery:
1) Shut the computer down
2) Disconnect the Magsafe AC adapter
3) Remove the battery
4) Hold the power button down for 5-6 seconds
5) Reinstall the battery.
6) Connect the Magsafe adapter to power and turn the computer back on.
This will reset the System Management Controller. One of the SMC's functions is reporting of the status and remaining charge of the battery.

Bluetooth device battery levels always read 100%

Blue Tooth device battery levels always read 100%

It's a known bug. (It may suddenly drop down.) Wasn't always like this.Appeared in one of the OS updates. Get Mighty Monitor
