Complete overnight battery drain when in sleep mode

When I close the lid of my Macbook Pro Retina, the battery of my MBP Retina goes down from full to zero overnnight.
Very frustrating because this basically makes that I either have to switch the Macbook off entirely, or that I have to connect it to the power supply.
No weird settings...
- Running 10.8.1
- Energy settings: default
- Power nap is turned off
- Happens with both wifi on / off
Does anyone experience the same issue? Is there a solution?

Battery condition is "normal". I have copy/pasted the information below (in Dutch only).

When in sleep mode iPhone 4 loses signal but when it's back on it searches and finds signal only recently doing this and because it's searching for signal battery not lasting very long please help

When in sleep mode iPhone 4 loses signal but as soon as its on again it searches and finds signal easily but because of this not getting calls or text msges and because it's searching for signal all the time battery not lasting

Here are some observations and a suggestion.
1) I mentioned before, that the number of views of this discussion forum is fast approaching 100,000. I suppose relative to all iPhones sold that is not a great percentage, but 100,000 still sounds pretty impressive to me. Consider also that many people probably have this same Sim problem and are not viewing this discussion forum because thay do not know it exists. How many people are REALLY experiencing this problem? Who knows. But I suspect it is more that 100,000.
2) To the best of my knowledge, Apple does not consult these forums as a guide to awareness of product performance. It may be company policy, but most of the time when I speak to an Apple employee they seem remarkably unaware of the "Top Stories" in the Apple Discussion Forum. This, despite the fact that my personal experience with customer service at Apple is excellent. So, as much as we of this discussion forum are confident SOMEONE important at Apple is reading all our posts and taking them to heart...I am not so sure.
3) I have been told over and over that the best way to gain Apple's attention regarding a problem is to post a comment on their Feedback Site. One comment about a problem is pretty worthless. 100,000 comments on the same issue, I'm guessing, will really get their attention.
4) Some folks have mentioned a recall to address this problem. Although such a thing is always a possibility, I don't see it happening. Why? When the brakes on a Toyota don't work, or that Toyata starts to accelerate without driver intention...well, that involves human life and the stakes are quite high. For many reasons you would see the automotive industry eventually be forced into a recall program under such a situation. But, a phone APPEARS to not nearly be such a life and death device. Or is it? My daughter's iPhone 4S developed a "SIM FAILURE" on the same day her car broke down in the middle of the very rural area we live at around 10:00 pm. She is 17 years old and was coming home from high school play practice. You can imagine the anxiety I and her mother felt when she did not arrive home on time. She eventually walked about a quarter mile to a house of a stranger and had to ask to use their phone to call us. Now, I am not saying that strangers where I live are not to be trusted. But, in addition to being worried out of my mind, I was not happy that an inoperative iPhone 4S caused my daughter to be put in this situation. My biggest concern now is...when will my daughter's iPhone become inoperative again due to SIM FAILURE?
5) The more folks in this discussion forum who post a comment about this issue in Apple's feedback site the more pressing this issue is going to be perceived by Apple. So, I like others, encourage all of you to do so. If this seems like a lot of effort, I offer you these few sentences below that you could just copy and paste into the feedback site.
The link to feedback site is: http://www.apple.com/feedback/
Feel free to use copy/amend/whatever the following as you wish:
Dear Apple,
I wish to register a strong concern about my iPhone's unpredictable inoperability due to failures somehow associated with it's SIM technology. For me, I do not consider this just a significant lack of convenience, but a significant safety issue. Should I need my phone in an emergency situation where it is experiencing a SIM FAILURE, I believe the iPhone will have put me at risk. I would ask you to please give fixing this problem your greatest priority and effort.
Sincerely, XXXX

Battery Drain - iMAC in sleep mode

I hooked up my 16g iPOD Touch to our iMAC, (USB connection) left it alone for a few hours-all set right? Came back to use the Touch and noticed the battery was drained. So I plugged it in again. The indicator shows it is charging, so cable is fine. I am thinking that when the iMAC goes to sleep it stops charging. If so, that bites but I understand. But why would it drain so fast? The Touch was half charged this past test and down to 20% in no time. Nothing running on the Touch.
Don't remember reading anything saying the USB port dies when in login mode or sleep. Usually don't charge it with this MAC, so sorry if this is an old problem. Usually use my MACBook or AC to charge.
Would you agree it's a sleep issue doing the battery drain?
Thanks

Yes, it because the compute is asleep.

Battery problem, anntena or motherboard? pleas help.

it could be a motherboard problem. Last month I spilled liquid on to my iphone and since I didn't have warranty for it I had to take it to a "phone doctor". He fixed it but mentioned that motherboard is working fine but he can not say for sure for how long it will last, and that I may experience some wierd problems. I'm having this exact problem the day I got my iphone back.
Well no longer but the solution still seems wierd. I turned on the "location services" because I saw in the "system services" screen that "cell network search" was turned on. I figured if I don't screw with location services, it would be okay. So, after three hours, I terminated the sleep in 10-20-30 minutes and 1 hour intervals, it seems I no longer have the problem but I'm going to sleep over it to be sure. Also make sure to turn on the "auto" option on the "carrier" menu.
I will post the outcome if I don't forget about this page.

Network disconnect when in sleep mode

Hi all.
Since I've installed Mountain Lion, any time the computer goes into sleep mode, networking do the same: I cannot download files, when the computer wakeup I have to wait the reconnection before being able to use mail, safari or ather network stuff.
I did not find any option to set, telling the computer waht to do when in sleep mode.
WIth Lion and preceding OsX this was not an issue.
Is there anything I can do?
Thanks.
Federico.

Hi,
Yes, clear "Allow the computer to turn off this device to save power" in the properties of network adapter\Power management as mentioned in the link provided by arnavsharma, and check if the issue persists.

Strange noises when in sleep mode???

Hello,
Have had my brand new 27 inch iMac for about 3 weeks now. This is my first Mac computer. When in sleep mode the iMac sounds like it wants to start up and then there is a clicking sound. Just wondering if this is normal. . .or, should I shut the computer down?
Thanks.

To me any clicking sound is not normal unless on a Mouse or Trackpad. Do not delay to have it investigated, take a look at Apple returns and refunds from here.... http://store.apple.com/uk/help/returns_refund

Phone not ringing when in sleep mode

Over last few days have had problem with iPhone 4S not ringing when in sleep mode. I have just spoken to Apple support. I had do not disturb scheduled , but this was staying on all the time , which I hadn't realised. This is a fault which should be sorted by 7th Jan. hope this helps anyone else with same problem, as I did search this site first.

This is the exact problem i'm having right now, I don't know why it's happening, but when i have it on the desk and when it's in sleep mode, I can get phonecalls and it won't ring but it won't show up as missed calls either, if i get a voice message i'll get it if i take it out of sleep mode and let it sit with full reception for a minute.
I also lose all reception while in sleep mode.

How do you prevent the computer from shutting down when in sleep mode?

How do you prevent the computer from shutting down when in sleep mode and plugged in?

Thanks tjk.
Those are great suggestions and got me looking in places I had not considered before. Unfortunately, the problem remains. The System Preferences did not have the shut down option activated and there are no parental controls active on the computer.
Any other suggestions are welcome.

QOSMIO x870 shutting down when in sleep mode

I'm not sure if this is working as intended or not.
I was working with the ECO setting to put my computer to sleep after certain amount of time. Once it was asleep for a certain amount of time, it would go into a shutdown/hibernation mode. It turns back on in the state that it was in when it went to sleep.
Also, if I have a program running and lock the computer, it will act like this as well when there is sleep time set.
I thought that I would be able to lock my computer and run a download over-night, but when I went to my computer in the morning, my computer was shutdown/hibernating. It came back up to where it was, but it appears that it hadn't continued the download for much over an hour before shutting down.
I don't think that this is intended, but I may be wrong.
I'm still digging around trying to find settings in regards to this. But I have hibernate turned completely off.
Is there some way to set the computer so that it won't shutdown/hibernate when in sleep mode and/or a locked screen?
In the meantime, I'm trying setting the ECO settings to "Sleep :: Never" to try to accomplish my download without the computer shutting down/hibernating during the process.

Thanks tjk.

Mac book air mid 2013, warms to approx 65 degrees when in sleep mode for 2 to 3 hrs?

Hello,
I have recently noticed that my macbook air mid 2013 warms up to approx 65 degs when in sleep mode for 2 hours or when I am doing my normal work. I am running Mevricks and I also use a moshi key board cover. Is it a cause of concern??

The keys without covers already transfer to a small degree finger oil to the LCD screen of the Air, even the thinnest keyboard covers place pressure on the LCD, however normally this would have no bearing unless stowed away in a pack with pressure, nevertheless causing dirt and oils is increased with covers to transfer more to the LCD, ....Macbook Air as well.
Beware of keyboard covers and using same
Beware of using thick keyboard covers on your Macbook, some pretty ones sold online are rather thick and upon closing your monitor, touch the screen and transfer more finger/hand oil to the LCD but at worst press excessively on the LCD display, especially in the case of the Air and newest Macbook Pro Retina. There is ultimately very little purposeful use of these keyboard covers if you keep your hands clean, additionally they do not protect against spills as many people presume they do; directly yes, but at the edges no. They also making typing a more challenging experience and run a fine line between 'serves no purpose' and 'possibly damaging'.
Screen covers protect against nothing and place an unwanted layer between the LCD and viewing, additionally if you dont touch same or dont have any pets that might claw at the screen there is no logical reason to have a screen shield.
dust will accumulate regardless. Realistically what are you trying to protect the screen from. The back is solid aluminum alloy, the front LCD viewing screen should never be intentionally touched.
outside of a sneeze or some debris which an extremely lightly damp cloth can remove, all else is dust. ...
Use a soft paintbrush or makeup brush for cleaning
One very useful tool for cleaning dust from the LCD screen, the hinge area of your notebook and around the keyboard, is a very soft inexpensive small paintbrush or a makeup brush. The less you wipe your LCD screen with anything like a cloth, the better. This small brush is very handy, quick, and ideal for removing dust from around and on your notebook.

OS X Lion: Fix for wireless not reconnecting when exiting sleep mode

http://www.tech-recipes.com/rx/18931/os-x-lion-fix-for-wireless-not-reconnecting -when-exiting-sleep-mode/

I have the same symptoms with a 2011 iMac and my Senheiser Bluetooth headphones.
10.7.3 did not correct this bug.
I'm also using MS Messenger and notification sounds are also buffered until the headphones are switched on.
I found other threads dealing with this bug :

"Success - in the Audio Midi Setup (Applications/Utilities) I changed the output to 2ch - 32bit Float and all the audio works well."
My headphones already had this setting, but internal speakers had 2ch - 24bit... is it a possible explanation ? Time will tell ...

Battery not charging when in sleep mode

This might sound like a dumb question but, is it normal that my shuffle does not charge when computer is in sleep mode? It's been plugged in for the last 6 hours and the amber light is still flashing. Can I change the sleep mode on my computer? surely I don't have to be working at my computer for 4 hours every time I want to charge the shuffle. thanks

You can also change your SysPrefs so that the Mac doesn't go into Sleep when you don't want it to .... for example, when you want to charge the iPod. You won't lose much by doing this; it can still be set up to shut down the display and your hard drive.
My own preference these days is to disable automatic sleep completely. If I wind up leaving for a few hours or an afternoon, I don't mind leaving it in the 'near sleep' mode that it goes into and even that happens only when I overlook putting it to sleep manually. You can do that with the remote, with the power button, or of course via the Apple Menu.

My iPhone5 battery dies when I'm not using it

My iPhone5 battery dies even when I'm not using it its like I put my phone down and it's a 10% then when I look at the battery later when I look at the battery it's like at 1% please help me thank you

Battery life seems short
Click ( www.apple.com/batteries/iphone.html) for tips on how to prolong iPhone's battery life.
Try turning iPhone off and then on again.
Connect iPhone to iTunes and restore iPhone.
If the screen shows a low-battery image, the battery is low on power and needs to charge for up to ten minutes before you can use it.
When charging iPhone, make sure to leave it charging until it is fully charged. You'll know the battery is fully charged when the battery icon in the upper-right corner of the screen looks like this .
Note: When charging using a computer, don't connect iPhone to a keyboard. Also, the computer must be turned on and not in sleep or standby mode. If iPhone is connected to a computer that's not turned on or is in sleep or standby mode, the iPhone battery may drain.

Iphone 4 battery draining while in sleep mode

I have noticed over the past few days that after putting my iphone 4 into *sleep mode* and not using it for several hours that the battery percentage is significantly lower after powering it back up. I first became aware of this after waking up to find my battery was at 50% (8 hours before I went to sleep it was 90%). Just today I was using my phone and the battery was at exactly 85%, I turn it off and an hour later I check the battery at its at 77%!!! I then go for a 45min run (leaving the phone at the house) and coming back I see that it is at 73%.
I don't know if this is a battery issue or a problem with the wifi/3g working when the phone is in sleep mode. My parents both have the 3GS and they do not experience this with their phones.
I have had this phone for 2 weeks and I don't want to have to send it back so please tell me this is a software/settings problem and not with the hardware!!
I haven't changed any settings or downloaded any apps since I got the phone (Except for the free case app). I did however sync my email address with the phone so it may be a problem with that I don't know.
I am also on the original firmware that came with the iPhone 4 I have not updated that yet.

I think it had something to do with the signal being weak. I normally keep my phone in the basement where my computer is and often there is only 1 bar or no service at all. In order to make contact with the cell phone tower the phone has to work harder therefore using more battery. I put the phone upstairs in my room last night where the is better AT&T signal and my battery has not dropped off at all.
That could be the issue. Your phone is only getting 1 signal or no service, and is trying to work hard trying to find good service in your basement. Try setting the phone on the first floor where you get good signal and see if that fixes your battery issue,.
