It depends on the uses you give to your computer, because the battery will have capacity for less time if you are using professional apps than using Safari. Theoretically, the MacBook Pro with Retina display battery should have capacity for 7 hours, but as I said, this will decrease depending on the apps

i brought battery charger for my mac book from the deferent store, and before i plug it to my mac book i want to verify that is genuine product. how do i get to know that?
It should have an Apple part number at the bottom of the charger and an embossed Apple logo on the face of the adapter.
Anyone can stamp a logo on the side, of course, so I would take a good luck at the part number and do an Internet search for the part number, making sure that it's genuine Apple.
Good luck,

Is anyone else having this problem? I rely on my computer heavily for work and school and this is just not acceptable! After paying $125 for a brand new battery I would have never expected these problems.
I'm sure that if you search hard enough, you'll find someone else who has had a similar problem, but that does not mean that it is remotely normal or common. Apple definitely needs to replace the machine, but don't be afraid that the same thing will happen with the new one.
Of course, that's assuming that this wasn't a case of user error. It's hard to understand how it could be, but in my years of tech support, I've learned to never discount such possibilities. I've seen people do things like forceably shove plugs into the wrong ports, seemingly oblivious to the fact that it doesn't fit and insistent that it should. -
How many hours does a brand new battery last after fully charged. I have a late 2008 Macbook Pro.
How many hours does a brand new battery last after fully charged. I have a late 2008 Macbook Pro.
clintonfrombirmingham is right, there is no way to exactly tell. But from personal experience, a new battery on a 2008 will last for about 2 1/2 hours with a higher screen brightness and doing something taxing to the battery (like gaming or running lots of 3D programs). But if you're just listening to music with the brightness all the way down, and no programs running, you could get up to 12 hours. So for average use, it should last you a whole business day (assuming you don't use it more than 30% 0f the time). Hope this kind of gives you more of an idea of what to expect:)

è normale che il mio mac book retina 13 dopo una settimana e mezza di vita abbia al 100%di carica della batteria solo 5 ore e 19 minuti di autonomia? quando ne prevede 7 da caratteristiche di listino?
Il tempo di 2 ore della batteria è calcolata usando pochissime applicatoins aperti, uch come un browser e un client di posta elettronica, e molto 'leggero' surf del web. Significato molto pochi video, impostazione di Risparm Energia impostato per massimizzare la durata della batteria, ecc Se potrai impostare il risparmiatore risparmio energetico per la migliore durata della batteria e si usa solo il vostro MacBook Pro con alcune applicazioni aperte, si dovrebbe essere in grado di raggiungere il intero 7 ore.

HT5423 How many hours is the charging time of the iPad 4th gen?
I am charging my ipad, & noticed that its been 9 hours & still its 90 percent. I just wanna know, how many hours is the charging time of an iPad before it gets 100% full? & is it normal that the charger become hot? Hope someone can answer this question. Thank u.
Chargers, and the unit being charged where the battery is located, will get warm during charging...charging does work on the battery. If it is hot or too hot to handle then you need to decide if it is too uncomfortable and needs to be checked at the Apple store genius bar.
Nine hours is a long time to charge, but if you discharged all the way it can take 4-8 hours to fully charge.
If the charger is getting very hot and taking a long time to charge you may want to take it to the genius bar and have it checked by the techs. -
How many hours needed to charge the new iPad when connected to the wall outlet.
How many hours needed to charge the new iPad wifi 16 gb?
Yesterday it was my first time to charge and it takes around 8 hours (it was not on wifi& not on working any application)
when connected to the wall power outlet using the supplied charger,dock and the USB wire.
I,ll be waiting for urs reply.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%.
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. Also look at The iPad's charging challenge explained http://www.macworld.com/article/1150356/ipadcharging.html
Also, if you have a 3rd generation iPad, look at

New iPad Takes Much Longer to Charge Than iPad 2

I recently went to the apple store in Covent garden and had a battery replaced for my Mac Book Pro 2009 edition.
After fully charging the mac the percentage guage meter displays the battery is losing power fast. 1% increments goes down every 5 minutes even if I have only a browser which is opened and no other running applications.
My recent test after a fully charged mac book pro allowed me a maximum use time is 2 hours!
I have friends and family members who have the same model as me and their mac book when running on battery, shows that the laptop has about 6 hours use. They are able to run multiple applications and use sites such as Youtube and still get a good 4 hours of use.
Anyway, I have booked an appointment with a Mac Genius for tomorrow to look into this issue.
I thought I'd just ask the community to find out if any of you can help.
Many thanks in advance.Thank you Donald.
You are the second person to tell me this so this is more of a reason for Apple to sort out issue for me.
The team there don't believe there is an issue with the battery.
Thank you once again. -

I would like to download iMessage for my mac book pro.
I would like to download iMessage for my mac book pro OS X, 10.8.1. When I try to install imessage it says that I need 10.7. What do I have to do to get imessage installed?
It sounds like you already have iMessages setup. Did you sign into iCloud from system preferences and did you also add your iCloud account to Mail?
They should, just sign you into iMessages when you load Messages.app.
If you are only being asked to put in your AIM id (which it is really asking for your APPLE ID) then it means that you are already signed into iMessages (hopefully)
To check this, go to Messages>Preferences>accounts and choose iMessages. Make sure that it says it is enabled.
Now close out of the preferences, and then hit cmd 0, to bring up the Chat Box.
The Chat box lets you use iMessages begin a conversation with a friend in your contacts.
simply type their name into the TO field at the top of the chat box and find a contact with "IMessages" next to their name. Hover over that contact, and if a blue Talk Bubble comes up next to the name, that account is ready to receive iMessages.
Click the account and begin a conversation.
If you have setup everything correctly with your Apple ID on your iDevices as well as in Messages on OSX, you should be able to have a synced conversation with all of them.
Please note, if you were using your Apple ID with iChat before ML, then you most certainly have an AIM account and you were using it in the past. If you want a buddy list, then you should follow the prompt to sign in with your AIM account, but treat it like it is asking you for an Apple ID. Sign in with your apple id to the aim account it asks you to sign into and then you'll have your old iChat buddy list back.
iMessages does not have a buddy list associated with it. you need to organize your Contacts with their user information and then you need to use the To field in the chat box to communicate and find people with iMessages. Only gtalk, jabber, aim, bonjour, yahoo have the ability to show you a buddy list. iMessages buddy list is Contacts.app
if iMessages is not enabled, you can enable it by clicking on the iMessages account in Messages>preferences>accounts and then signing in with the same apple id you have tied to your iOS devices.
I hope this helps. -
Bought and installed a new battery for my Mac Book Pro 5.1, intel Core 2 dual, the computer makes a lot of engine noise! The noise disappears in sleep mode. What can be done?
I bought it from Other World Computer last week for $95. 3rd party, I suppose.

Two good points, in which case I believe the ethernet port can be disabled, (it can on my Pro);

Highlight the Ethernet option and click the gear icon at the bottom of the panel. There should be an option to, Make service inactive..... -
I just received my Mac book retina yesterday and the battery doesn't last more than 3 hours. I read through the other forums, but the dock doesn't seem to be draining my battery because it operates at 1% only. I keep the resolution to scaled with more space (the second to last in scaled configuration) and am using just safari with my wifi on. I turned of the bluetooth. Even with the resolution set to Best for Retina Display, the battery didn't last longer than 3 hours.Any suggestions?
I agree with Shah_Min, you SHOULD return it but try something else first as this drastically helped me...
Power down
Power on and immediately press Option-Command-P-R until you hear the initialization sound twice.
Release all 4 buttons
I do not claim to know what this does or why it helps, but I live 60 miles from the nearest Apple store so it was worth a try for me...
I immediately started getting 7 and even 8 hours of battery life without touching my settings. -
