My battery is getting drained even when the system is off

Hi
It seems my battery is getting drained even after shutting the machine down. While shutting down the laptop it would show battery as 100% charged and after swhen I start it after day or so it would be 93-94%. I am noticing this fromquite a some time.
Could anybody suggest, what could be the possible reason for this.
My macbook is late 2011, 13 inches.
Thanks

Do you mean your iPhone was exposed to high temperature and now the battey life is very short? If so, take it to an Apple store genius bar and have the techs check the battery and see if it needs to be replaced. Lithium-Ion batteries are very sensitive to high temperature so there may be damage to your battery if it got very hot.

My battery life is draining even when IPad is powered off?

I've had my iPad2 for about 15 months now, of course just out of warranty, and within the past week the battery has gone to ****. Before a charge use to last me 4-5 days with usage and on stand-by the rest of the time. Within a night it suddenly changed to that over a 8 hour stand-by cycle that the battery would lose 30-35%. I did a restore to see if that changed anything and it didn't. Went to the Genius Bar and they ran a diagnostic test on the battery and said it was still running excellently at 100% function. He suggested a few things to help preserve battery life but couldn't replicate the problem.
I went home and did a full clean sweep, getting rid of all apps and settings and shutting off my cellular data, in case that might be the issue. Then let the battery drain down until it died. I recharged it back up to 100% over a 24 hour span. Then I just left it sitting there untouched for the next 18 hours. Over that time he battery drained 60%. I again took it to the Genius Bar and they said that was normal, I disagree and understand that standby still uses battery but 60% really? They said at this point the only thing I can do is live with it and just turn my iPad off when I'm not using it or they can replace it for $250. I don't have the money so I said I'll just live with it and turn it off. That was on Tuesday. I spent Tuesday and most of Wednesday using it very little and noticed the battery was doing well. Thursday it was charged back up to a 100% and I read and used it for a few things then went to bed at 2:30, before going to bed I turned the iPad off with a battery charge of 88% and let it be.i woke up at 1030 and just turned it on and now the charge is it 62%. Since typing this it had gone down to 57%. From my understanding this is not normal at all. The Genius Bar so far doesn't know what the issue could be other than something in the software and I am out of ideas. Is there anything you can recommend? I'd really hate to spend the $250 but at this point with no usage to very little usage the battery life won't last much more than a day.
Thanks for any help you might be able to offer and sorry for the long read.

My iphone 4s got water in the headphone port. I put my phone in rice for 24 hours and the LED light is on. It stays on even when the phone is off. How can I fix it with out spending 200 bucks at apple to have them fix it?

Short answer is you probably cannot. Once water gets inside the device and it is powered on, the damage likely is permanant.

Zen 4gb battery draining fast even when the unit is off

Hi,
I have the zen 4gb. I also have the newest firmware loaded onto it. The battery goes down fast even when off. I also notice that if I go and turn it back on after 24 hours it appears to be still in standby mode. Any ideas? Thank you.

I remember the Zen Micro power issue (bought one for my son). That one was where the player stayed in "standby" when you powered off for many hours. This enabled a much quicker start up, but also resulted in some battery drain while "off". They changed this from 24 hours standby to 4 hours, I think. My Zen Touch did the same thing, but had a big battery so the drain was not so bad. It started almost instantly from standby, vs. maybe 20 seconds from true "off". The Zen (I have a Zen 4GB) seems to have a similar feature. I am not sure how long it stays in standby mode before shutting down completely.

Ipod Touch Battery is Drained even with the Ipod Turned off? and how long the batery goes on Stant Mode?

Hy ;D I bought an Ipod touch 4G 3 mouth ago , and recently the i noticed that the battery is drained even off .... is that normal? I turn him off( with the red bar) and put out side the bed , when i Wake up tha batery is about 80% ... (no Wi-Fi on)
And How long the ipod battery goes with the stant mode ?
Thanks alot for any one

I did a test on mine.
My 4th generation model running 4.3.1 last 10 days on and in sleep mode.
At the end of 10 days I got the 20% low battery warning.
I would try a RESET on yours.
Hold down the Home button and the Sleep/Wake button at the same time until you see the Apple logo.
It will reset and restart itself in a few minutes.
See if that helps.

Why is my battery discharge completely overnight even when the device is not in use?

Why is my iPod battery draining completely overnight even when not being used and no apps are left open?

That happens sometimes when you have wifi on and some other things on. To maximize battery life see:

Playlist shuffle is working even when the button is off...Im using Ipod shuffle 4th gen*

Im using Ipod shuffle 4th gen...And I am not able to stop the songs getting shuffled....For example I want my ipod the play the songs one by one...but its not working...Its shuffling songs by default...I mean the button which stops shuffling the songs(the on off button when placed in the iddle stops shuffling songs) is NOT working....What to do?

If you are trying to play a playlist in the order shown for that playlist (in iTunes), you need to be IN the playlist on the shuffle. You may be in the main "all songs" list on the shuffle, and not a particular playlist. Note: You can have multiple playlists on 4th (and 3rd) gen shuffle, which is why there is a separate "all songs" list.
This article explains how to use VoiceOver, including how to change between playlists.

I feel like an idiot for not having spotted this - it was indeed the problem. Not sure when/how I turned this on in the first place but the issue is now fixed.
It's pretty easy to do accidentally if you swipe up the Control Center without meaning to. I also turn of my BT by accident this way every now and then.

Battery drains even when asleep.

Hi,
I updated to 10.4.1 and now my battery drains even when the computer is sleeping.
I didn't change any settings.
Any thoughts?
Thanks.

I set up my brand new ibook today and am a bit confused. I calibrated the battery tonight and it is charged 100%. I plan to use it tomorrow. Should I unplug it from the wall and let it sleep tonight? Is that the normal procedure? Then use it tomorrow and recharge the battery? Or should I shut it down completely (like I do with my PC notebook) and start it up again tomorrow?
Also - with the new ibooks, is there still the problem about maintenance scripts running in the middle of the night while the computer is sleeping?
Thanks!

Battery drain even when iPod is off and hold button is on

The battery on my 20G click wheel is draining too fast.
If I do the battery test and let it run, it goes 12 hours fine. If I want to find certain songs or what-not, it drains the battery too quick. I know it does use more battery, but it's ridiculously to the point where clicking through to a few songs drains a quarter to half of the battery. I'm not leaving the backlight on, either.
Now, the battery seems to be running when the iPod is off and the hold button is set. The other day I charged it with the lock on, unplugged it, came back a day later and saw the charge was gone. Last night, I had half a charge when I turned it off, turned the hold on, and could hear a little noise through my headphones when I turned the hold on. Today, no charge.
Any ideas, or is my battery toast? I have already restored this iPod once, so I don't think it's a software problem.

Problem: Fan at full speed all the time - even when the Mac is turned off

Hello,
my Mac mini suffers from a very strange problem. I've had it for half a year now and recently bought a new power adaptor since my old one got damaged. I plugged it in and everything was fine - until half an hour afterwards, when the fan suddenly made itself noticeable at full speed. But it didn't stop; it went on, curiously even when I shut the Mac mini down. That's right. even when the system's turned off. The noise is really unbearable and only stops when I plug off the power cord.
Any ideas why this is happening?

My Mini started doing this yesterday. I came home from work and the fan was going full blast. Even after shutting the machine down, the fan would continue to run at full speed (and it is LOUD...much louder than my full tower desktop PC with 4 80mm fans). The only way to stop the fan is to completely unplug the Mini from the power supply.
I doubt that this is due to faulty wiring as my Mini is plugged in to a very nice UPS unit that conditions the power.
Now, I'm willing to admit that this may be entirely my fault since I have upgraded my Mini with 1 GB of RAM, a Pioneer DVD burner, and a higher capacity hard drive. However, the Mini has been running 24-hours-a-day for 5-6 months since my final upgrade, so it would seem that my upgrades are unrelated to this issue. Also, since someone else is having the same problem, again, my upgrades seem unrelated.
I was told on another forum to try resetting the PMU, which I will try when I get home today. If it works, I'll post. Seems unlikely though since the fan runs even when the Mini is powered down.
If anyone has any other ideas, I'd be glad to hear them. I'm assuming that my Mini is no longer under the 1-year warranty since I have performed so many upgrades myself, so, if this problem is something that can only be fixed by Apple, then it will probably cost an arm and a leg.

My Battery indicator keeps blinking when the system is switched off.

HI,
My battery Indicator keeps on blinking when the system is switched off. When there is a AC power supply this indicattor ceases to blink. I removed the battery pack and put it back but the problem remained.
As my battery pack was old I also bought a new battery pack and charged it before using but the problem remained.
thanks...

I will be really helpful if someone can help me out in this.

Should the FW 400 port be sending power to the FW HUB When the Mac is off?

The title says it all. I am using a refurbished 2007 Aluminium 20 inch IMac and after I shut down the Fire Wire ports still power the FW 400 Hub, is this normal? I have just stopped cutting power supply with surge protector because I was having trouble getting the Imac to start and leaving its' power supply on made the start up faultless. Could the "shut down" instead of "log out" be the cause?

Hey JustSomeGuy, thanks for solving the problem. The "cause" you were curious about is the choice when stopping to choose "shut down" instead of"log out", I'm not sure what the second one[log out] would do when I wanted to start the iMac again.
PS: my USB peripherals don't get enough power when the iMac is off to have them show lights indicating power, but I believe you are right. When I had the iMac in a surge protecter, so it was cut off completely from power it had BIG problems with starting up, for some reason the iMac must have access to power to always start up as it should.

Even when I charge my Mac Pro to the full bar, the battery seems to be drained even when I am not using it. Example, after charging it full, i switched it on the next day and its 79% battery left. Is there something wrong? help please

Assuming you are disconnecting from line power, when you say switched on, do you mean it was shutdown or in sleep mode? If sleep mode the battery will still drain because sleep still keeps some things active and the battery does drain a little. However, to go from 100% to 79% charge overnight is a bit excessive in sleep mode. Unless you have some processes set to activate over night by the cron file and do things like backup the system.
What are the statistics on the battery, the apple in the upper left corner, About This Mac, More Info, System Report, Hardware, Power...things like battery Condition, Capacity, remaining charge, voltage, current.

Should I disconnect the charger once the battery is 100% full. Or can I use the laptop plugged even when the battery is full., Should I disconnect the charger once the battery is 100% full. Or can I use the laptop plugged even when the battery is full.

You can leave the charger plugged in, as you cannot overcharge...charging automatically stops when your battery is full. Once every 2 ~ 3 months, its a good idea to drain the battery to about ~ 40%, then recharge to full. Otherwise, you can charge whenever you like & leave connected whenever you like.
Try to avoid full battery discharges, Lithium batteries don't like that & frequent full discharge/recharge cycles will eventually kill your battery.
