Does leaving an Ipod pluged in kill the battery?

I have a dock/speaker combination for my ipod. I use the ipod with these speakers as an alarm clock, so i have to leave the speakers plugged in all night. Does leaving the ipod plugged in like this kill the battery? in some places ive heard that it does, but in others ive heard that it doesnt have that big of an effect at all. Which is it?

In fact, as long as your iPod isn't hot, the battery likes being topped up.

Does closing out of your apps on iphone kill the battery?

I heard that closing out of you apps on your iphone is like when you "force quit" on your mac and it kills your battery instead of saving it.

Not true. If anything, running fewer apps will help conserve the battery.

Does leaving ipod Classic constantly docked damage the battery or the screen?

I have the iPod Classic 160GB. I rarely use it at home, I prefer to play CDs and vinyl, but use it when I'm on the go. So, when I'm at home it's constantly plugged into a docking station, with the 'charged' symbol on the screen all the time. Will this cause any damage to the screen (such as screen burn), or the battery?
Thanks

No. As long as you periodically discharge the battery when you are using the iPod then recharging it, you are using it correctly. Although most of the following relates to notebooks, some of it is quite relevant to your iDevice.

Does charging your computer too long really kill the battery?

Does charging your computer too long really kill the battery? I have some friends who claim this happened to thair PCs, and my friend's iBook G4 has about ~3 minutes of battery life because of this. Has Apple fixed this in later models or should I still only charge it until just as long as it takes for it to get filled up?

Mac power management is now, and always has been, very smart. The Mac does not over-charge its battery.
Batteries have a limited lifetime, and they eventually wear out whether they are charged daily or never charged at all. Your friend's G4 battery, if original, has lasted a very long time. It is not dying due to over-charging, it is dying due to old age.
For longest battery life, follow the recommendations in the article shldr2thewheel cited above.

Leave your Mac On or Shut it Down???...What the Genius Say?

Hi Guys!!!!!
What do you think about leaving your Mac On or shut it down when you are not using it????
Thanks.

Hi,
Sleep mode has to supply power to the RAM memory in order to facilitate rapid wake-up. On the MacBook, safe sleep is the default mode. The MacBook will wake itself up when the battery gets low, then save the memory image to a disk file before the battery runs out.
In another thread, the same question came up. Users reported sleep would use about 4% of the battery every day. That seems very reasonable since a lithium ion battery will often discharge a few percent per day just sittig doing nothing.
I turn my MacBook off when I am not using the MacBook. I am impressed at how quickly the MacBook boots up rom being totally off. If you are a heavy duty multitasking person, the obvious advantage of sleep is the applications you were usng last time are open with the files you were woking on already open when you wake up the machine.
If you worry about wearing out the battery, you can change the sleep mode with the command line tool called pmset. You can use pmset to set the default sleep mode to always deep sleep to disk. The disadvantage of deep sleep is it takes longer to wake up, but is does reduce unnecessary battery use.
This thread discusses the use of pmset:

Leaving my Mac Plugged in?

Hey guys, I have a few question about my MacBook Air. I recently got a new Mac for the 4th time but this time I got a notebook the past years I owned Desktops so I do not know that much about the battery, I know what charge cycles are but, is it fine to leave my computer plugged in all the time? I heard that new batteries do not get overcharged so Im not worried about that. My friends however told me that if I want to reduce the amount of charge cycles I should keep it plugged in but deplete a whole charge once in a while? Is this true or will keeping a battery full for a long time like a week or so damage the battery? Im trying to keep this computer in good condition like always with all of my products Im just a little too sensative with electronics. I do some work on my air like slight video editing and Photoshopping when I am not home I use Adobe Premiere CS6, After Effects CS6 and Photoshop CS6, when I render a video it depletes the battery which is annoying so I was wondering If I should plug the computer in during renders. I know I shouldnt be doing video edits on a Air but I dont have a choice sometimes.

NEVER let your Air die from lack of power, not due to battery, but doing same can cause a file corruption.
LiPo (lithium polymer, same as in your Air) batteries do not need conditioning. However...
LiPo batteries do NOT like to be dropped to close to 0% Try to keep it above 10% or so, and drop it to 10% or less as little as possible.
Contrary to what some might say here, LIPo batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity.
Same way you dont take a new car out and speed and rev the engine hard first 100 or so miles.
*Cycle count / use/ lifespan is one thing that cant be countered.
Proper treatment is another. Just because LiPo batteries dont need conditioning in general, does NOT mean they dont have an ideal use / recharge environment.

Does Apple kill the battery at a set number of cycles?

The battery on my macbook pro dropped from 47% capacity to 10% at 475 cycles and additional charge/discharge cycles do not increase that number. Coincidentally (or not) my first battery also died at EXACTLY the same number. It was still in Applecare when the first one died and the phone tech said ÿeah, that's about right."
Does Apple have a bomb planted in the battery software to force replacement at 475?

Batteries are designed to be able to have working the 80% of the capacity after 1000 charges. If your battery doesn't support that or you see that your battery is dying, the battery is defective, so you should take the computer to an Apple Store
Verrrry interesting. What is the source of this information. Is it from Apple or is it generic engineering data? I'm heading into Chicago in two days and plan to stop by the Apple store. I would LOVE to be able to quote their own specs if possible.

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.

Macbook Pro retina display 13 inch stopped charging. Charger LED also not on while plugged in. The battery fully drained off but the system can detect the charger when it was switched on.

Macbook Pro retina display 13 inch 2014 model stopped charging. Charger LED also not on while plugged in. The battery fully drained off so the system can not be started but the system can detect the charger when earlier it was switched on before draining off the charge. Charger type magsafe 60W.

Once you have examined the power inlet on the computer for dirt, and made certain that the pins on the end of the MagSafe cord are free to move in and out to make contact, there is very little you can do yourself.
You will need to visit your Apple Store (FREE with appointment) or your Apple-Authorized Service Provider (policy varies). They work on these all the time and have good expertise and lots of spare parts to try to determine the problem.

I have an iPhone 4, but the computer does not not recognize, do not recharge the battery if it is off

Did you already try another USB cable or USB port?
Did you try to reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again?

What's the fastest way to kill the battery...

hello friends. i was wondering what's the fastest way to drain my macbook pro battery so i can calibrate it? i want to kill the battery not the laptop if you know what i mean. thanks.

Turn on wifi + bluetooth and turn the brightness all the way up, and if its a new mbp, turn off the automatic video card switching in energy saver. Then just play youtube videos / movies / games (anything that uses the vid card as much as possible helps) till it goes flat.

I'm using a Rocketfish USB to Lightning cable for powering my IPAD2. But when I plug it in the battery icon beeps and comes on then goes off...then goes on...then goes...all beeping every time. Its as if its being unplugged and plugged in over and over.

I'm using a Rocketfish USB to Lightning cable for powering my IPAD2. But when I plug it in the battery icon beeps and comes on then goes off...then goes on...then goes...all beeping every time. Its as if its being unplugged and plugged in over and over. It won't stop...and its not charging....just beeping. I've check connections. Any ideas?

- While charging try resetting the iPod:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- Next try restoring the iPod via iTunes. First from backup and if still problem restore to factory defaults/new iPod.
- However, I really think that the iPod has a hardware problem and an appointment at the Genius Bar of an Apple store is in order. If defective Apple should give you a refurbished iPod.

HT1222 The new iOS 7 update is killing the battery in my iPad. I have checked online and taken measure indicted to help this - but the battery is dead within hours. I am very frustrated. Can I undo this update??

The new software update - iOS 7.0.2 is killing the battery in my iPad. I have searched online and taken the recommended measures to decrease battery use, but within hours my iPad is completely dead. It would take days to kill the battery before this update. I am very frustrated. Can I undo this update???

This typically happens when some apps on the phone were interrupted by the upgrade. When it comes back up the app tries to resume and can not. You have to find and kill that app(s).
Do you have an Exchange account?
That is usually the culprit. Go into Settings and turn off all of the toggles for the Exchange account. Then reset the phone (hold the Sleep/Wake and Home buttons and don’t let go until the screen goes dark and the Apple logo appears). When the phone powers back on, turn the toggles back on.
Do the same for all mail accounts if you don't have Exchange or that doesn't resolve the issue.
If it is not Exchange/Mail then it could be another app(s).
With iOS 7 you can control what apps run in the background. Go to Settings > General > Background App Refresh. This will list all of the apps that can run in background. Turn them all off and restart. If this fixes the problem turn on a few at a time until you find the one causing the trouble.
