How Long Does the iMac's Battery Last

Hi. How long will the iMac's battery last if you use it 8 hours (how about for 16 hours) a day and shut it down when you go to bed.
Thank you in advance.

As long as you leave the machine plugged into a live power source, even when it has been turned off it will still draw a bit of power to maintain PRAM and the clock chip, and will not use the battery.
The battery is used only when there is no othe source of power available. And, it is not recharged in the iMac.

How long does the average iPod touch last?

Not the battery, I mean the actuall iPod. How long does the average one last before it dies? How many hours?

Judging from this support site, the average iPod lasts until it falls into a toilet.
Each of my first, second, and third generation iPod Touch models are still working flawlessly. That's thousands of hours. Like Macs, they typically become functionally obsolete before any particular hardware failure ends their life.

How long does the restore form backup last?

Hello, I got exactly the same problem. I bought two iPod Nano 2 GB one for me and one for my wif and hers was just ok. Mine on the contrary got a message from itunes that was not possible to transfer the musics to my iPod because there was no space on disk. And this without using it. I installed the updater from january 2006, but when trying to connect and update it there's a huge delay and the iPod Nano screen continues with the Do not disconnect message. Then I tried to restore it but it's displaying the same message for more than two hours. I am going to shut the restore dialog box and then disconnect it from windows and try to see how it goes...
If you have any ideas please give me some help.
Tks

On average how long does your mac book battery last?

Mine runs about 1.75 hours on average while doing my best to conserve the battery. I would like to get an idea from other mac book owners how long their battery lasts, so I know if something is wrong with mine.
I know there are a number of factors that come in to play in terms of how long your battery will last. For instance, i know that if you have a lot of applications open, and if you have blue tooth device it will cause your computer to have to work harder and in essence will cause your battery to run out faster. It just seems like mine runs out real quick (1.75 hours). I have the check mark by "better energy savings" and close my applications as well.
I will also say that I did not calibrate my battery when i first got it being that this is my first laptop and i didnt know. I calibrated it about a month after i got it. However, prior to the calibration i had it hooked up directly from a power source all but one usage. Being that it took so long for me to calibrate my battery, is it permanently damaged?

A charge capacity of 4860, while being below average, is not a complete didaster and is not the cause of the 1.75 hour usage. Mosre than likely your failure to calibrate is the reason for it being below average. I does say to calibrate ASAP in the user manual that comes with your MacBook.
Now, to help with your battery time the things that affect the batery time the most are…
1) Processor performance. Make sure your Energy Saver setting are set for maximum battery savings.
2) High processor usage. The more you use you procossor the lower your battery times. So, you will get better battery performance when checking/writing e-mail and web surfing that you would encoding video. I often use a tool like MenuMeters…

… to keep an eye on my processor usage.
3) Screen brightness. This is a huge battery user and you should set this as low as is comfortable. High battery times require the screen to be set to minimum values. One spot (minimum) is the norm.
4) Wireless networking. As this is always on it does chew up more battery that you would think. Turn it off when you don't need it. I actualy created a "no networking" profile in my Network System Preference for when I want to maximise battery performance and have no need of internet/networking.
5) Bluetooth. This also consumes quite a bit of power for something that is not used much. Turn it off as much as you can when on battery.

How long does the ink cartridges 564 last in a C309a

I recently bought a used C309a printer, the first thing I did was buy new ink cartidges. The old ones were 564 so I bought them again after I installed them I have used the printer less than 15 times and most were blk. copies, I am already getting a low ink signal for the colored ink, did I get bad cartridges or do these not last very long? At this rate I cannot afford to use this printer! Any ideas as to what is wrong, also I have only had the new ink in about a week and a half.

My HP Photostat C309g printer shutdown due to low ink in 564 black photo. I had to replace the cartridge to run the printer. I have not used the Photo feature so it should not be empty. Is there a way to over-ride the printer shutdown due to low ink level ?

HT4623 Hi!My iPAD lost its charge fast !!I've got an iPAD capacity 57,1GB and it has available 55,1GB ,version 7.0.4 .I'd like to know how long does the battery last when it is 100 % charged.

Hi!I've just installed the iOS 7.0.4 operating system and the battery lost its charge at an incredibly speed.I'd like to know how long does the battery last if everything is right when it has 100% charge.Thanks!

I`m `propping` up this thread to to the top of the forums again as it`s been three months and not a single community member or Apple support personnel have replied, which I find discouraging.
I`ve tried everything - both the iOS device(s) and Apple TV have been upgraded (albeit reluctantly) to the latest versions, since iOS 7 looks like crap compared to iOS 6. Both use the same WiFi network. Bluetooth is set to `off`, as per the online tutorials on the Apple Support page.
I also tried shutting all of them down, including the router, waiting 30 seconds and turning the router, then the Apple TV then the iOS device on sequentially with 30 seconds in between each, again as per this discussion forum, and still nothing.
Why can Apple not make a technology, such as AirPlay, work with greater than 10%?
Any other ideas?
Come on, people.
Thanks,
Doug

I refurbished my macbook air 7 months ago because there was a problem with the steady state drive. Now my battery seems to be dead again. How long does the warranty last? Do I need to pay for a new battery?

I refurbished my macbook air 7 months ago because there was a problem with the steady state drive. Now my battery seems to be dead again. How long does the warranty last? Do I need to pay for a new battery?

As I wrote Apple will diagnose an Apple product even if it is out of warranty for free. That should be your first step to find out if the problem is the battery or something else.
Once you have Apple telling you a 7 month old battery is defective (if that turns out to be the case) then it becomes a game of horse trading. You'll need to speak to the tech and when he tells you there is nothing he can do you will need to speak to the tech manager and when she says most likely there is nothing they can do you go to the store manager, etc. It is unlikely (though possible) that they will give in easily you need to be firm, polite and let on that you're willing to accept a partial reimbursement.
So again the first step is to find out what is wrong.
good luck

How long does the IPhone5c battery last for without hardly any usage with about 2/3 to 3/4 left?

How long does the IPhone5c battery last for without hardly any usage with about 2/3 to 3/4 left?
Has the side affect of charging, where the battery's life gradually decreases overall with each charge, been fixed ?

Eric,
They did say 12-14 hours, but as is always the case with such estimates, they invariably quote the 'best possible scenario' and almost never mirror 'real world' conditions.
If, from a fully charged position, you simply switch on your nano, and set it to continuously play through a long set of songs, with EQ off, backlight off, modest volume (50%) don't touch it during playback, then you might just get somewhere near this figure - and if you don't then it's either not been conditioned properly or it's faulty.
If you use it like me, daily for a couple of hours, with 2 secs backlight and switch songs regularly, using fairly high volumes then 6-8 hours is more likely. It'll even drain when it's not in use, even in sleep mode, albeit very slowly. They also tend to drain more quickly before they've been through their first few charge cycles (the conditioning period).
Personally I haven't got a problem with this though I can understand why some people have. It's not very impressive in this respect. Apple should be able to come up with something much better - maybe they should talk to Sony

Until it dies.
That would depend entirely on what you do with it and how much you use it.

How to make the phone's battery last longer ?

Hi everyone,
i am wondering if there is any difference when the battery is fully desharged thus the phone swithes off , and then you plug it into the power outlet to be charged.
or if it is not fully decharged, and it has some one or two battery bars on the upper right corner of the display, and you set it to be charged, is there any signifficant difference between these two states ?
is there any official or technical advice on "How to make the phone's battery last longer " ??
thanks in advance.

It depends on the battery.
Charging the battery when there is some power in it is especially bad for NiMH batteries. The loss of power is called "memory effect" - battery "remembers" that it does not get fully utilized and over time starts supplying less power.
But new Nokias come with Li-Ion or Li-Polymer and the effect on these being charged when there is still power in them is negligible. Especially for the Li-Polymer ones.
See here about batteries and "memory effect":

http://en.wikipedia.org/wiki/Memory_effect

How long does the full charge last?

How long does the battery last on a full charge

Hi Jason,
The iPod nano (3rd Generation) has a battery life of 24 hours of music playback and 5 hours of video playback. This will deteriorate over time as the battery becomes consumed. Total charge time should be around 3 hours.

Hello i:
i wonder how long it will last..since im on the go..i prefer to use wireless keyboard rather typing at my macbook keyboard..
There is no way to answer that since battery life is a direct function of use.
and how long does the magic mouse last>>? hours??
There is no way to answer that either for the same reason.
Carry extra batteries with you or use rechargeables and carry the charger.
