Macbook pro (13-inch) battery life?

Hello,
I've bought a Macbook Pro (13-inch, mid 2012, non-retina, OSX Yosemite 10.10, i7 processor) 3 weeks ago and I was wondering how long the battery usually lasts and what I can do to increase battery life.
Currently it only lasts up to 5 hours, despite it promising 9 hours of battery life. This is mostly while using Google Chrome and iTunes. It feels like I'm recharging it constantly and it already has been through 23 battery cycles - at this rate my battery would only last 3 years which would be shorter than my previous laptop did and I expect more from something that cost twice as much as my previous one.
So am I doing something wrong? Is there something broken or is max 5 hours of battery life normal?
With my previous laptop I also used to take out the battery and use only the adaptor to save my battery, but as I can't remove the battery of this laptop I was wondering if leaving the adaptor in while working at home so it remains at 100% would be a good idea or would that actually be worse?
Many thanks in advance!

The battery life is stated as "up to" 9 hours, not promising 9 hours. Having said that, I would suggest using a browser other than Chrome, as it is often considered a battery hog. Also note, it is perfectly fine to use the computer with the AC power connected. As a rule of thumb, use it AC power when available, and on battery power when portability is required.

Slow i7 MacBook Pro startup and battery life issues

Hi Everyone,
My i7 2.66GHz 15" MacBook Pro with 8GB of RAM does a couple of things that worry me
1. The battery life is poor, 127 Charge Cycles, 6 months old. I'm sat on Chrome with one window open and it's reading 3hr 16 min on 83%
2. The startup into 10.6.5 is painfully slow. It seems to load up the menu bar at the top and hang mid flow, just before the battery status and time remaining appear.
Any ideas?
Thanks in advance! Mike

There seems to be a lot of unanswered questions floating around here.
Its kind of scary seeing some of these "issues" and not seeing any answers.
I just spent 3 g's on a 2011 mbp, and I am really hoping all the great things that I've learned about Apple still rein true. Those are the only reasons I bought one.
My startup is very slow as well.

MacBook Pro Snow Leopard battery life

Okay, I've been poring through the threads for days now to try to find a solution to this . . .
I have two different MacBook Pros (a 15" 4,1 and and a 17" 1,2). I've upgraded both to Snow Leopard. Each is now running 10.6.6.
After uprading, both started suffering extremely poor battery life, losing nearly 1% each minute, even when the Mac is sitting and doing nothing.
I've done all the fixes I've found (recalibrating the battery, resetting PRAM, checking for rogue processes, etc.), and so far nothing has fixed the problem. I even bought a new battery for the older Mac, and that had absolutely no effect.
Some of the threads I've seen here go back for more than two years.
Has anyone solved this problem? I'm at the end of my rope!

1% a minute?
You're quite right - this problem has existed for years. Apple bases its power estimates on a device half intensity, using Energy Saver, and SL is supposed to have better battery performance than Lion.
Something is causing your battery to die on you. Check off the following one by one to make sure there isn't another problem:
1. Are you attached by USB? If you leave your MBP attached to a USB device or Firewire cable, you can lose battery power even if your computer sleeps. Disconnect all devices when you're not using them.
2. Are you using Energy Saver? Your machine may be sapping energy by being at high intensity. Instead, opt for a monitor at half or three-quarters brightness.
3. Losing battery even while sleeping? That problem can be addressed by going to System Preferences/Bluetooth and disabling Bluetooth.
4. Are you losing battery through heat? You can lose battery capacity with a system that's hot all the time. Keep your machines as cool as possible, through energy management, getting a laptop cooler, or using free applications like Fan Control.
5. Limit your losses. Use a power cord whenever convenient to increase your real-life battery time.
6. Some applications, like Skype that are on all day, sap battery power. If one such application is on all day (or close to it), this may be part of the issue.
7. Don't upgrade to Lion. This OS demands twice as much power as SL.
I don't want to minimize the significance of the issue, but take a look at which processes are drawing power. You might want to go to Utilities/Activity Monitor at take a look at which applications are consuming your CPU.

Macbook Pro Retina 13" Battery Life - Need Advice

Hi. I bought my first ever Macbook Pro Retina 13" a few days ago. I am mainly going to be using it for college work, listening to music and watching youtube videos in my spare time. And browsing the net of course.
I was wondering what is the BEST way to charge my laptop in order for me being able to use it for a long time when its not plugged in? Do I let the battery go all the way to 1%? I did that the first two times and I am worried because I've heard its bad. Or do I let the battery drop to about 20% EVERY TIME and then charge it? Or do I charge it whenever I need to and only let the battery drop to about 20% a few times a month? I am really confused. Ive been on many different forums etc and everyone is saying something different. As I said, this is my first macbook and I don't want to ruin the battery life.
Any help would be greatly appreciated.
(Sorry if I've put this post in the wrong community.)
If you need any more info about the Macbook, ask away.

Macbook Pro (2012 April) Battery Life Reduced A Lot!

Hi guys I got a macbook pro sometime around April 2012 and the battery life just went down drastically in a couple of months i have no clue why before it used to show upto 7 hours something initially but then it started showing only 4 hours or so i feel something went totally wrong with the battery is there any way to fix it please give me some helpful suggestions thanks! By the way i must mention this today i was watching the percentage meter it makes absolutely no sense first it showed 7:08 today on 98 percent then within few minutes it went to 6:28 in 97 percent so i think somethins is very strange with the battery. Just yestarday on 99 percent it was showing 4:38 hours please help me fix it.

As others have said the battery itself is perfectly OK.
The reason your remaining charge shows only 4:38 after it has been fully charged may be explained by one or more processes that are responsible for excessive power demands. To isolate that potential cause read: Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity
Because i have turned of put harddisk to sleep as someone on forums suggested to another user that turning that off can help stop freezing problems when opening lid

MacBook Pro - late 2013 Battery Life declining

I have noticed in the last couple of weeks that my Battery life is not what it used to be. Until recently, I would be able to charge overnight, and then take to work with me and have on most of the day without being plugged into the mains and still have 30 or 40% battery left when I get home. Now it seems to decrease quite rapidly and even more so once it gets past having 40% left.
I also noticed last night that when using Chromecast to stream to my TV, it really eats up the battery.
I have a 15" MacBook Pro, SSd pro-retina - I have not yet upgraded from Mavericks to Yosemite as I read so many people having issues with Yosemite.

1. Check the cycle count of the battery against the rated life for your model. The battery may be due for replacement. If the power adapter is connected almost all the time, the battery may need replacing even though the cycle count is not too high.
2. Follow these instructions, or these for OS X 10.8 or earlier.
3. In the Energy Saver preference pane, uncheck the box marked
Enable Power Nap while on battery power
if it's shown (it may not be.)
4. You can also try resetting the SMC.
5. Make sure your system is up to date in Software Update.
6. Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

Macbook Pro (Non-Retina) Battery Life

Just recently purchased a non-retina MacBook Pro, 13" with the upgraded i7 processor. So far, it's lots of fun, just one small question/concern...
Does the battery life really suck on this one, or is it just mine that possibly needs service?
The estimated remaining battery time keeps fluctuating, which is understandable, which attempting to constantly calculate; however, I score perhaps three hours of life using only web (Safari) and iTunes (transferring songs to/from iPhone, etc.) I haven't even installed my Adobe CS collection yet, and I'm afraid it'll constantly be glued to the wall adaptor, thus defeating the purpose of an expensive, beautiful laptop.
Anyone believe this to be common, uncommon, or bizarre perhaps? I've got AppleCare, of course, so worst case scenario, I create a TM backup and send in for inspection/repair

There is an authorized Apple store not far from me, but I've only seen one technician there ever, and they'd most likely send it out for service or something anyways.
Any web browser I have attempted to use (Safari, Firefox, and especially Chrome,) is listed under "Apps Using Significant Energy.." though Firefox and Safari have only stated that when more than one tab is open, doing searches. Chrome states that upon opening the app- weird.
There is no constant video streaming, only videos on occasion, likely via YouTube; all that's one with iTunes is syncing with the external hard drive that houses the files, backups, and playing music- no iTunes Radio, Podcasts, or of the sort. Also, iTunes (almost) never shows in the Significant Energy column- only seen it there maybe once.
When using the computer, I see the calculated battery life jump from seven, to five, to three something... which reminds me more of my ancient PowerBook. haha. There has been nothing done so far other than small, meddling tasks- non-significant sized file downloading, occasional video, and the bulk of it just retooling the iTunes library- still restoring it from scratch
I just want to be certain that there's no significant energy usage hidden here. This machine has the 2.9ghz i7, with maxed 16gb RAM- would that differ anything from the original spec models that people test and claim to have some solid battery life? (I don't mean the new Retina or Air models) It seems fine when I unplug it from the wall, but drains quicker than expected. Once I start drawing and editing, I'd like for this machine to last more than an hour

Using magic trackpad affect macbook pro retina's battery life?

Hi, I just got new macbook pro 15 with retina. I was not sure how much it affects on macbook's battery while using the Magic Trackpad or Magic mouse. If it affects indeed then how much...thanks...

You are using Bluetooth if you have got a Magic Trackpad, so it affects the battery. However, it's not a big difference respecting to using the built-in trackpad or a USB mouse, so I wouldn't worry

Macbook Pro has short battery life and runs hotter after firmware update

I installed the macbook pro EFI firmware update yesterday and now my MBP runs hotter and the fan starts running earlier than it has ever done before. Also, my battery lasts 51 minutes from a full charge whereas, before the update, it lasted 2 hours (using the same programs and display settings).
Has anybody else seen this problem?
Please tell me I'm not alone with seeing this. I am hoping that there is a solution and it's better than 'buy a new battery'. The fact that my box now runs hotter with the fan on more constantly would not be solved by a new battery I think.

Also had the problem of MBP running much hotter after most recent Firmware update.
My fans have been running at 6k RPM constantly, and processor Temps have been running at 70-88°.
Following the advice in this topic, I checked the Activity Monitor, which told me both my account and my son's account (which was running but had no actual applications running) had separate Airport processes going nuts – each at approx 80-95%!
Switching off airport and logging out of my son's account almost immediately started to cool the processors, and the fans began to slow down. Switching Airport back on doesn't seem to heat things up again, but if I start to crunch numbers, it all happens over again...
So who knows why the firmware update is making these processes freak out.... weird.

I have a early 2011 Macbook pro 13 inch, I'm running Lion 10.7.4, and i want to upgrade to 10.8 Mountain Lion. Is it safe for my computer or are people experiencing problems with displays and Battery life?

Do Not post stuff about how Airplay doesnt work, because i dont have Apple TV and dont need to hear about it.

If you have an external drive equal to or larger than your internal HD, clone your internal to it with either Carbon Copy Cloner or Super Duper. Test the clone to make sure it's bootable. Then upgrade either one. Try it out first.

How long is the Battery your Macbook Pro 15 Inch (2011)

I might get a Macbook Pro 15 Inch 2011 with the 256GB SSD and the High Resolution Screen!
How much Battery Life would I get?
1) Going on the Internet
2) Running Skype
3) Playing Flight Simulator
4) Running Word
OR just list how long your battery is on your Macbook Pro!
Thanks!!!
(Will the higher resolution display affect my battery life)?

I was saying all of those combined on the newest MBP
if you're just worried about word, depending on the version, it might not even run on the computer.
And surprising as it may be, web browsing, depending on how you browse and what plug-ins you have installed, can be a very intensive task that takes up CPU and memory.
I found a very good discussion specifically about your issue but the site is riddled with ads so just google "MBP battery life 2011" without the quotes for further information. (it's very vast)
Long story short, bring your power brick with you if you take your computer out. There are also extra battery options that are said to help you charge your computer however, the magsafe power adapter is Apple propietary hardware that no one is able to make unless it's an Apple branded product so these batteries usually have a three prong plug (depending on where you're from) to pluginto with your power brick.

Is it possible to use a new battery for a MBP 15" in a MacBook Pro (15-inch Early 2008) ?

i have an old MacBook Pro (15-inch Early 2008) and my battery is as close to dead as it can be. I was wondering if I could replace it for a new battery that works for the latest models.

No, that's a 60 watt. You need an 85 watt.
