Hello,
playing a while with the System Status app didn't reveal unusual ongoings, except for regular errors in conjunction with the process "kbd". Does anybody know what the following intermittent warning means and whether it matters?
Regards,
Martin

IPhone 4s shuts down (battery drain) but still have charge???

Hi!
For some reasons, in the last couple of weeks, my 4S has started to shutdown. when trying to power it back up, the screen indicates that the battery is drained, but I know there is. As soon as I plug it in, it eventually powers back on, confirming that the battery was far from drained!
The first time, my battery was at about 60%, and just yesterday, it was at 19% before it just shuts off...
Anyone have a clue? or does this indicate my phone might have e defect?

Sorry about tthe triple posting. Apple's website was responding strangely and not indicating that I had posted.

Wifi/battery drain

i have updated to iso 4.0 and the battery drains when the ipod is in standby mode. this happens because the wifi is still on when it is in standby mode is there a way to make the wifi go off beside turning on airplane mode or turning wifi off?

Hello IevonBOS,
You are unfortunately another victim of battery draining when updating to iOS 4.0 on iPod (Touch?). This is a major issue that lot of people encounter at the moment and that Apple has not aknowledge yet. You'll get tons of details in this thread: http://discussions.apple.com/thread.jspa?threadID=2474499&tstart=0.
We suggest that you file an Apple iPod Touch feedback ticket and you send your information into FredCG Google docs formulaires. Everything is in the following post : http://discussions.apple.com/thread.jspa?threadID=2474499&start=705&tstart=0
Basically it is still very difficult to really root caused the source of the problem (iOS? Apps? Notifications? Wifi? etc). You'll find a short summary of what should be done in order to maximize chances to cut down battery draining here : http://discussions.apple.com/thread.jspa?threadID=2474499&start=750&tstart=0
Nevertheless you'll have to keep in mind that wifi use under iOS 4.0 seems to be much more intensive for the ipod battery than wifi under iOS 3.x.x.

My Mac Pro shuts down prematurely. Seems the battery drains almost instantaneously, once it hits about 50% or less.

My Mac Book Pro shuts down prematurely, seemingly doing a rapid battery drain when it reaches < 45%. I can only work, while on battery for approximately 15 minutes even when starting out fully charged. Although, a full charge now only reached 95% - 97%. Can't recall if it ever reached 100. Looks like the battery has about 240 cycles on it. I thought at first it was over heating, but now not so sure. Heat may be normal levels. Does this mean it is time for a new battery?

Apple menu > About this Mac > more information
scroll down to Power and click
look for Battery Health Information, Cycle count and condition.

Reset your SMC and NVRAM/PRAM

Iphone 4s shuts down when it battery life gets to about 17%. prior to IOS 7 it would shut down at about 1%. What's up? (Oh, when I plug in recharge, the battery indicates it's at 17% or so. So, I'm not referring to battery drain).

My iPhone 4s shuts down when battery indicater reaches about 17%. When I recharge, indicater shows about 17%, so apparently this isn't fast battery drain. Oh, this happens since IOS7.

See if your phone is one that Apple has noted as requiring a replacement battery: https://www.apple.com/support/iphone5-battery/

Turn off cellular for apps and they turn back on. Fast battery drain. Shuts down at 30-40%. Battery reads "0" when but rises quickly to 17

Turn off cellular for apps and they turn back on. Fast battery drain. Shuts down at 30-40%. Battery reads "0" when but rises quickly to 17 & charges. Happened after IOS upgrades. Have 3 iPhone 4S for 1-2 years & 1 iPhone 5, w/same problem.

Back up and restore using iTunes.

My computer shuts down instead of sleeps when battery drains...

Hi there!
So, I just got a new MacBook Pro (the better 15" one) in June. I've noticed, however, that when my battery drains, and the little warning comes up that says "your computer will go to sleep in a few minutes to preserve data," if I let it run all the way out, it doesn't go to sleep but just shuts down. When I reopen my computer after plugging it in, all my stuff is back, but I do have to press the power button and start it up again.
My old computer (White MacBook 2006) always actually went to sleep, and only if I let it sleep for a long time did it shut off.
Have they changed the behavior? Do the laptops only shut down, and no longer sleep when the battery is gone? Or is something wrong with my computer. I'm getting all my data back, and all the windows and stuff are still open, so that's not a problem for me, but if my computer is working incorrectly only three months after buying it, then I'd like to know...
Thanks! Let me know what further information you need to help!

Your computer is not shutting down — it's hibernating, also called "safe sleep". This is indicated by the fact that everything you were working on is undisturbed when you wake it by pressing the power button.
The contents of RAM are written to the hard drive before the machine enters safe sleep, so that if the battery drains completely before you wake it, the contents of RAM (including your unsaved work) won't be completely lost. This is different from ordinary sleep, in which the machine simply suspends all activity without writing anything to disk. If the machine went into ordinary sleep after giving you a low-battery warning and not getting any cooperation from you (i.e. you didn't heed the warning and plug in AC power), and then you didn't wake it for twelve or fifteen hours, the battery might have gone completely dead and your unsaved work would be lost.
In short, yes, this is new behavior compared to several years ago, and from what you tell us, your machine is working exactly as it's supposed to.

IOS 7.0.6 sound, powering down, and battery drain issues

Since updating my 4s to iOS 7.0.6 I'm having trouble with my sound. While I'm trying to watch YouTube videos or Netflix, one minute it will be ok then the next it will just go silent. It's almost like it thinks there are headphones in the jack but there aren't and when it does this I can't even turn the volume up or down. I've tried everything I can think of... Hard reset, killing the apps, searched in the settings, ect. I don't know what to do and it starting to really irritate the living **** out of me because it never did this before the 7.0.6 update. Also since the update I installed I've been having serious issues with my battery draining at a very rapid rate and this too I've killed all the apps running in the background, lowered the brightness, and all other battery stuff I can think of. AND on top of all of that since this new ******** update I can't even turn my phone off! I slide it to power off and it acts like its going to shut down like normally, the screen goes black and all looks good and then wouldn't you know it the apple logo pops back up about 3 seconds later with out even touching the phone.......... SOMEONE PLEASE HELP ME!!!!

I have an an iPad air and I updated it to IOS 7.0.6
- no battery draining issues
- no overheating
IOS 7.0.6 does not brick any device.

After IOS 5.0.1 upgrade - Battery drain from 100% down to 78% the following day

I had charged my iphone 4S battery to 100% and my ipad battery to 100% also: both upgrade to 5.0.1, I had plugged it out and I had left it on stand by before I go bed. The following morning I noticed iphone 4S battery down to 78% and my ipad battery down to 99%. Surprised with iPhone 4S battery drain so quickly and where is coming from? I had to re-charged it again thro car charger. Happy with iPad 2 battery.
On iPhone 4S I had turned off all notifications accept Messages, EirText Pro, WhatsApp and Tango . The Location Services is switch to off competely. I have gmail account setting to push to off and manually get the emails. iCloud switch to off.
Is there any advised on the battery issue or is Apple to issue another upgrade 5.0.2 to solved the battery on iPhone 4S?

After two days trying out the problem with my iPhone 4s battery - I had "reset all setting", set up WiFi again and disable all location completely, change the notification list. My Gmail account setting to push to off and manually get the emails. iCloud switch tooff.
I had drain the battery completely until iPhone is dead as requested - I had it off for about ten minutes before re charge fully for overnight. I noticed battery had drain rapidly during day if I use messages and emails.
The next day I had re-charged fully to 100%, then plugged it out and I had left it on stand by before I go bed. The following morning I noticed iphone 4S battery down to 84% the same.
It hadn’t makes any differences or am I missing something…

No sleep but shut down when battery drained

Hi there,
just bought a new battery for my MacBook - what happens now is that when I get the battery drained alert (10 min) my Mac quits just about 2 minutes thereafter. Unfortunately it doesn't go to sleep so I have to reboot it after connecting it to power...
Any thoughts? Thanks!

macbig, you haven't read much about recent Apple notebooks, have you? All portables since the first white MacBook has had a 'Safe Sleep' mode, which is supposed to activate automatically when battery power drops below a certain level. Active memory is saved to disk, and the computer shuts down all power draining activities. It is then essentially completely off. The difference between this and a standard shut down is that when the power button is next pressed (with a power supply connected), the system resumes after a short wait, with everything still open, just as it was left. This is very similar to a Windows PC's hibernation mode.
What the original poster here is describing is the problem I am having which brought me here. The safe sleep mode fails to activate, whether the system is active or sleeping. It instead just shuts down hard, as an older model would. In my case, this behavior has been intermittent since my original purchase a year ago. I have calibrated my battery, reset the power management unit, and all the other recommended fixes. My battery is in excellent condition, and in my case, this shutdown doesn't occur until the indicated level is actually at 0%. Nevertheless, it is a feature which is supposed to work, but doesn't. I'm hoping someone else here has experienced this and found a cure.

Battery draining down to 20% overnight??

Does anyone else have a problem with their battery? I have charged it up and then I totally switched it off (ie. not on 'sleep'). Overnight the battery drains to either dead or down to 20% without me even using it!!
Is it better to keep it constantly in sleep mode?
Any ideas or tips would be really helpful.
Cheers.

I recently performed a upgrade from 7.0.5 to 7.0.6 and I found that my phone battery drain up very fast and the battery unable charge to 100. Besides, the battery live is going down when I charging with 3G on.Any solution for my issue? Please help.

Hi, I had my iPhone 4S and I'm recently upgraded it from 7.0.5 to 7.0.6 and I found the battery drain up very fast if compare to iOS 7.0.5. Besides, I also unable to fully charger my phone to 100% now - max is 85% with phone either in airplane mode or switch off totally
May seek help from your advise on above case.
Thank you
Best regards,
Adrian

Try killing the battery (Let it drain---turning on all the settings, playing a video, and having the brightness up kills it faster), then let it fully charge from there. Let me know if that works.

Battery draining/over heating issues - 925

hi all,
ive had this issue for a while now but havnt moaned about it until now but ive just had enough of this constant issue and want some help
i have the lumia 925 and have the above simptons, i have the lumia amber update and have disabled every setting and background app the only thing i have enabled and running in the backround are -
touch display is turned on (double tap to wake)
on my home screen i have the apps - Photos, Battery, Bing news, The Weather Chanel, set as live tiles
the backround apps i have running are - Battery, Bing News, Facebook and whatsapp
apart from that all other settings are disabled or off
i can disable bing news if have to but i dont think this is the issue here as before i was having the exact problem
one time i noticed a 30% decrease in battery, not to mention the battery got really hot in hand

Hey Robert,
If it's anything like my 920, sometimes it gets caught in a CRAZY battery drain cycle. Sometimes it may get hot, sometimes not, but I always make sure that my GPS is working correctly. A lot of times it's not, and I need to reset the phone by either turning it off or holding down the power and volume down buttons.
Especially check any apps that you may have downloaded that may be using GPS. Also, if you do the power + volume down, always turn your phone off again the normal slide down way afterwards or your live tiles won't update correctly.

Multitasking on iPod Touch 4G, running iOS 6.1.2, nearly impossible. Opened, background apps do not seem to stay in memory and must "reload" every time I switch back to them. Also, intense battery drain (imo).

Let's say I'm playing Words with Friends, and also Angry Birds. I may want to go back and forth between the two. When I do so, the app that was in the background needs to reload again. There is no quick access or ability to quickly resume where I left off. And the reloading means that the app restarts from its opening screens...so if I was working on a level, I have to start all over again. And quite often, a game like Angry Birds will lag greatly when I first open it...moving almost in slow-motion.
I don't know if this is typical behavior when playing multiple games, or if I have an issue with my device. I've rebooted and even reset and restored, all to no avail.
There doesn't appear to be as much of an issue if I'm playing one game but also have the music player open, or Safari, Notes, Reminders, etc. Those will resume just fine, though there may be some lag when opening/re-opening them.
So I guess the problem seems to lie within 3rd party apps, and not the apps that are part of the iPod/iOS.
The other problem is battery drain. I do all of my music listening via Bluetooth, so I expect that to have a greater impact than if I were using plugged in headphones, and I have location services turned on. But I have most notifications turned off, all email accounts set to manual and not push, screen brightness turned down and auto brightness turned on, "ask to join networks" turned off, auto-lock is set to 2 minutes but I almost always turn off the screen immediately after setting up my music listening (since I do so at work), volume limit turned on, EQ turned off, sound check turned off,
With these settings, my battery can drain 20% or more within 10-15 minutes of game play. And these are not what I would consider memory intensive games--just Words and Angry Birds.
I've installed (and recently uninstalled) a couple of battery meters from the Apple Store as well--freebies. Carat, Battery Doctor, Battery HD, Battery Magic.
Carat and Battery Doctor seemed to offer the most pertinent and accurate information so the others were uninstalled long ago.
The Accelerate tab in Battery Doctor show the amount of memory in use, and the amount of available memory. The vast majority of the time, the memory in use is approximately 94%. I will occasionally choose to "accelerate" which supposedly frees up memory, but this "bump" lasts only a brief time and I'm not sure it's a great idea.
Even with absolutely nothing open or running, my used memory is generally still above 80%.
Carat, if anyone is familiar with it, shows a J-Score. My J-Score is 17, which means that my performance (according to Carat, anyway) is better than only 17% of the users who have Carat installed. In other words, 83% of people are getting better performance from their devices. It also has "battery hog" and "battery bug" sections. It doesn't detect any hogs or bugs.
I use my iPod Touch in rather limited ways. A typical day consists of approximately 5 hours of music listening via Bluetooth and 30 minutes to 1 hour of playing the aforementioned games. The occasional note and reminder, perhaps a brief check-in with the weather, and that's about it. And wifi is in use only when at home (there is no hotspot at work). Still, I need to charge it every day. I'd be keen to do more with the iPod if I could count on it to last more than a day.
I've read up on multiple forums and blogs for tips on prolonging a battery charge, and believe I've taken everything into account, and applied whatever I could. I've even reset the network settings and try to discharge the battery completely once a month (for supposed battery calibration).
I'm really hoping people can offer some suggestions or comments on whether this is typical behavior or if my battery is going, or even offer some additional tips.
With iOS 7 on the horizon, I'm hoping the upgrade will offer some resolutions (I've read there is better multitasking), but considering how weakly my device performs at this point, I'm not entirely convinced that an iOS upgrade will actually make any improvements.
Thanks a lot for reading.

No, the app does not have to completely restart. It gets shifted in its open state into storage. Similar to how a computer uses the hard disk when it has insufficient memory.
What complicates things is that sometimes memory does not get returned for reuse when you close an app. Thus yo should periodically double click the Home button and "delete" unnecessary apps from the multitasking dock and power off and then back on the iPod.
