Battery and infrequent use
I only use my MBA on occasional trips. What's better for the MBA and the battery? - power the MBA off leaving it connected to a power source or disconnect it from the power and charge it only when needed.
Stupid question but how do you tell if one your cores has shut down? Activity monitor?
My MBA has been great since I bought it 3 months ago, quiet and cool. Just uploaded to iPhoto then closed then a bit of browsing and it's suddenly boiling hot on the left side and the fans are at 6200. I am charging it right now but that's not happened before. I usually don't push it at all - just word processing, internet, photos.
Also, I never have it directly on my lap (as Apple states) - I have it on a thin bread board so blocked vents can't be the problem.
Thanks.

Emergency Services and infrequent use of Skype
As a member of a small remote fire brigade with no mobile coverage and unreliable landline phone, I established a Skype account with credit. The idea is to have the ability to call from a laptop via satellite Internet access in an emergency when there are no phone services. This is not a service that will be regularly used (hopefully) but remains dormant. Having to re-activate the credit defeats the purpose as this is likely to be required at a time of emergency. Is there a way for emergency services to be exempted from this rule?
Hi and welcome to the Skype Community,
Here's some really important information for you: https://support.skype.com/en/faq/FA29/can-i-call-an-emergency-number-from-skype
The most important part is that for most countries we do not actually terminate calls to emergency numbers. So you might want to revisit your set up in general.
No back to your question about credit reactivation:
This process is instantaneous: As soon as you click the reactivation link on your Skype web account page you will be able to use it right away. We don't have the capability to exclude individual accounts from that credit deactivation, I'm afraid. -
I want to store my ibook. Can I take out the battery and simply not use it for months?
Just bought a new imac and want to mothball the laptop. Can I simply remove the battery and not use it?
Do I have to recharge the battery every few months?
Can't see the point in leaving it plugged in as its not being used, yet in case I need it as a back up would like to keep it.
Any comments on proper procedure?
thanks.From Apple:
Storing Your MacBook Pro
If you are going to store your MacBook Pro for an extended period of time, keep it in a cool location (ideally, 22° C or about 71° F) and do one of the following to preserve your MacBook Pro battery life:
Discharge the battery 50 percent before storing your MacBook Pro.
When storing your computer for longer than five months, discharge the battery to approximately 50 percent and then remove it from the MacBook Pro. If you are storing your computer for an extended period, recharge your battery to 50 percent every six months or so. -
Hello i have one IPhone 4S and I use 3G net in my mobile sometime I have problem with temperature in my phone at the SIM card or battery how can I fix this problem. By update or version of 6.1.3
Could it be because the SIM card got damaged while I cut it to fit the IPhone?
Very likely. Hard to believe the carrier in Mexico doesn't have a micro-SIM card available.
Or somehow the Chinese carrier found out and locked it?
No, which is not possible.
What can I do? Get a new SIM and see if it works again?
Get a micro-SIM from the carrier in Mexico that you don't have to manually cut down. If that carrier doesn't provide one, switch to another carrier that is not so low-budget. -
My phone is lost. When I use "find my phone", it says that my phone is "offline". It has a charged battery and I hadn't turned it off. When I call my number it immediately goes to the voice mail. Does that mean someone has found it and turned it off? What should I be doing. I have used icloud to lock and send a message to my phone but if it is offline does that do anything? HELP!!
Welcome to the Apple Community.
It may be that someone has turned it off or it may be that it has been lost in an area where there is no reception. The best thing that you can do, is contact your provider and let them know that you have lost your phone, and change your iCloud password at My Apple ID -
I just got a MacBook Pro and I used Home Sharing to transfer my library from my PC. However, my PC's battery died in the middle of the process so only half of my music was transferred. The sharing option no longer shows up on the left. Do I need to start completely over and delete the content in my new library to prevent duplicates or is there a way to continue the process?

I am using iPhone 5 and tried to Erase All Contents and Settings but it is just showing an apple sign on the screen and nothing is happening now for about 3 days now. All it does is eat up my battery and still show apple sign after charging! Help!!!!
Hi DaVince Vince,
I'm sorry to hear that you are having issues with your iPhone. I also apologize, I'm a bit unclear what issues you were having that led up to the attempted Erase All, and/or exactly what behavior you are seeing now (restarting, not responding at all, etc). If you are seeing an Apple Logo screen and your iPhone does not appear to be starting correctly, you may find the following articles helpful:
If your iOS device restarts, displays the Apple logo, or powers off while you're using it - Apple Support
If your iPhone, iPad, or iPod touch doesn't respond or doesn't turn on - Apple Support

How can I use the battery and let it be perfectly healthy?
Hello everybody!
I love this forum because everyone is a great helpful person.. .. However, I'd like to ask you couple things about the MacBook battery...
I know that now the battery has been improved, it leasts longer and it can support 1000 charging cycles.
(Right now I'm performing the battery calibration)
I'd like to know how can I use the battery and let it be perfectly healthy.
For instance,
1) If I connect the laptop to the MagSafe and let it charge, when should I remove the plug from the Mac and when should I put it in charge? I don't wanna continously waste cycles and let my battery die too soon (it's too young to die! :-D ) .. I use it mainly at home connected to the MagSafe: someone tell that even if you leave the MagSafe connected after the mac has been charged it stops charging (I can see this), and others say that is not a good thing to let the mac connected to the plug for a long time... with the old model I used to disconnect the battery from the mac so I didn't have these problems but with the new one it's a long procedure...
2) I usually use to calibrate the battery once a month... Is it a good thing?
Thanks!

Old battery for home use and 1 "traveller" battery? good idea?
My powerbook is my main computer and is connected to the adapter 90% of the time.
Would there be a noticable benefit from only using the new battery if i need to go on the road and leave the current battery in the laptop for home use?
If so is it best to leave the new battery half charged when not in use?You might want to read this page on the same site as the previous link, because most of my opinions are based on sources like that one, since I am not myself a battery expert.
So what would you class as a shallow discharge? 50 or
75%?
This is going to sound stupid, but I don't really put a number on it, only because I haven't seen one. I only see the advice about shallow vs. deep discharges. But I also don't think it needs to be that precise. The most damaging percentages seem to be 0% and 100%. I am not sure there is so much difference between 50% and 75%. Also, it's pointless to finesse it around that range because if you are on battery and you need to work longer, you should work longer. Being able to use the runtime you bought is more important than ekeing out incremental runtime preservation. I think this is why Apple's advice is so general, because it will essentially accomplish the goal. ("An ideal use would be a commuter who uses her MacBook Pro on the train, then plugs it in at the office to charge.") Unplug it when you need battery, and plug it back in when you don't need battery.
As the battery will sometimes "rest" for a month or
more should i follow the apple battery care
suggestion and leave it at 50% ?
That seems fine. The page I linked to says 40%. Other sites say 40% and in the fridge. Again, anywhere in the ballpark is probably Close Enough.
Network, do you leave the battery at a specific
charge when resting?
Resting plugged in, 100% obviously, can't do much about that.
Resting and not in the laptop (short term offline), I aim for 90-95%. The only reason for that is on the site I linked to, it says "The worst condition is keeping a fully charged battery at elevated temperatures," so I figure it's easy to not have it fully charged. However, I will not drain it to 40% for short-term room temp storage, because that would require planning at least an hour ahead to charge it back up to 100% before going out the door. If you forget to do that, you walk out the door with your 40% charged battery, and that 5ucks.
Resting long-term, I'll drain to around 40%, put it in a ziploc bag, and put it in the fridge. Some say getting it down to fridge temperature isn't important, and I really don't know. But all agree, never put it in the freezer!!!!!
There is a balance here between convenience and runtime preservation. If you wanted to obsess over runtime preservation you could drain to 50% and fridge it every time you take it out of the laptop, but the reason that's totally stupid is that every time you want to use it you have to get it back up to room temperature and charge it. That's why I like to have different criteria for might-need-it-today storage (almost charged, room temp) and long-term storage (half discharged in the fridge).
The reason i'm hammering at this is that this
powerbook is nearing the end of its cycle and i doubt
i'll invest in another battery in the future.
Totally understand. That's why I looked into this stuff myself. But since I have a battery that's pretty new, and I think I can get decent runtime out of it for at least 2 years, that means it should last long until the ol' PowerBook G4 feels out of date enough for me to upgrade.
The main points here are, if you want to use your battery for its intended purpose, don't worry about micromanaging the percentages, just use it normally, don't drain it every time, keep it cool when possible. -
My iPhone 3G 16gb in white: I did all the things you mentioned, but it just keep looping the Apple logo and doesn't turn off until it is out of battery, and I am using a MacBook Pro 15inch Unibody if that does matter
If you are in Hong Kong, go to Digital Trade, 1/F, Sincere Plaza, Argyle Street, and it will cost you 120-150HKD, but before you go check that your power button and home button are working correctly, if not press as hard as you can, hope this will help.

Is there a app that will tell all apps that are running and possibly how much battery power they use?
You don't need an app to do this. Here's how you get the battery info. Go to Settings>More>Battery. This will show you all the active apps and their individual battery usage.

iPad revers back to a home screen from another page being used, IE Facebook Good battery and wifi signal. Sometimes several times in a couple of minutes. Could there be an problem with internal hardware
Hi there
My wife and I have been dealing with a very similar issue with our iPhone 5ss, all battery drain issues started after the upgrade to ios 7.03. We have performed numerous restores and have had 3 trips to the Genius Bar. Finally they gave us new iPhones (yesterday). We had hoped this would do the trick but we have the same problem on the new phones.
This morning I restored one and didn't sign into iCloud. Battery drain is now gone. And when I deleted iCloud from my wife's phone it too went back to normal. So I believe the culprit is iCloud and I am now testing various setups with iCloud to determine which app/setting is causing the problem.
Hope this helps with your phones. I will post again if I can narrow it down to something specific.
Good luck! -
I have the new iPad. Even with airplane mode on, my battery life is extremely limited. Is there a problem with the battery? I used to have the ipad2 and had no such problem.
What is your brightness setting & how many apps are open?
The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

i am using iphone 4s its under warranty , phone got automatically turn off even if has 50% battery and not get on until i connect to charger . if i go to service center will they change my phone ? and will i have to pay anything if its battery issue ???/
Take it in and see what the technicians say is wrong and then how they want to handle the iPhone. If the iPhone has a problem covered by the warranty then you should have no problems.
